How to instill illumination in the minds of the home. Programs for visualization of illumination VS Luxmeter: what can a smartphone see for illumination? The illumination of the primitive lies directly from the power of light, how to look like from the dzherela

Light meter, mabut - yakis vimiruvalny pristіy... But for the value of the control, it’s not skinny to give an impression. Kindly, I’ll guess about the illumination in the room to the workmanship. Apparatus of meanings for the definition of one of the characteristics of the light environment. Namagaєmosya reporting visvitlity of the food supply: recognition, the principle of building and attaching the methods of yogo vikorystannya.

Three of the theory

In the Internet, there is a great rogue in scientific and technical terms, as well as in light technology. One and the same attachment is called in a rational way. Tsey pristriy is a light meter, for example, it can be seen behind the light flow, I wish it was not so.

Illumination light is a characteristic of an illumination element, and speaking of the value can be deprived of a specific illumination dzherel (lamp rozzharyuvannya, gas-discharging element, light-emitting diode). The unit of the central characteristic for the CI system is the lumen (lm). The price of light is 1 candela (cd) for a solid kuti 1 steradian (SR).

Change the parameter behind an additional photometric cooler (spherical integrator) with a diameter of 1 or 2 meters or with wall integrated spheres measuring 10 cm to a meter. All this, of course, is not for a by-by-by-by-by-by-means rate, but the price of a small, small-scale attachment of TKA-KK1 to the control of svitlodiodiv to become 35,000 rubles.

Potency of light, which is going on one area, to turn around in illumination. One of the characteristics - lux (lx) - is the result of illuminating the surface of 1 m² with a stream equal to 1 lumen. The concept of "illumination" is not carried up to the illumination, but to the navkolishny midst. Svitlovy potik є the value of the post-dermal point for the dzherel, so that the lightening of the dermal point is due to the accumulation of the number of chinniks:

• number of dzherel, which is known to be in order with mice vimir;
• svitlovogo vice of the skin from them;
• vіdstanі to dzherel;
• depicting the versatility of furnishings.

What is also a luxmeter and for whom is it needed?

"Vimіrya everything, so that we do not give in to vimіru, but we do not give in to - zrobi vimіryuvanim" - a whole aphorism that is attributed to Galiley, pіdtverzhu, so enlightenment can be imіdіated. Oskilki її is one to serve as a luxury (walnut - light), then the first attachment for the illumination is called a light meter (meter - vimiryu). Stagnate as in the middle of the primacy, and in the open space. What kind of vipadas are victorious?

Installed, as weak as it is, so overwhelmingly, light is unpleasantly on the processes that pass through the brain. When there is no illumination, there is a decrease in patronage, a decrease in the concentration of respect, and a decrease in sleepiness. It is overwhelming to create light to the disturbance of the nervous system. And those, and іnshe, change their minds for the harmless vipad. To that, before the planned visits from the protection of the workers on the working missions, enter and reconsider the visibility of the working missions. GOST R 55710-2013 will establish standards of illumination (for suites) good value... Forgiven, in the office of the sanitary norms and rules (SNIP), the coverage of ma buty is from 200 to 300 lux.

The process of photosynthesis in roslin, the result of which vyroblyayutsya lively speech from the coal of the meal, to be seen in the flow of light. With a lot of growing lines, they react in a different way to the temperature drop and the level of illumination. Practically all cultural growths and a large number of vegetables grow well in the minds of the world illumination. The most vivid views are up to high temperatures and illumination. That is why it is luxuriously victorious to control and provide the necessary illumination for agricultural crops in hothouse state gifts, greenhouses, botanical gardens.

Attract that principle of robotics

The basis of any light meter is a photocell - for example, a conductor attachment, for a light meter, it transfers its energy to an electronic device, for a result, an electrical system. The power of the strum is proportional to the amount of illumination there, if there is a photoset.

The largest element of the light meter is an analog or digital indicator. At the mechanical annexes there is an electric strum, which is transformed by a galvanometer, a wicker-like collapse of the shower's arrow. Digital attachments analog signal(electric strum), with the help of an optical-electronic converter, it will be converted to digital from the displayed result on a crystal display. Structurally, offended by a university (photo-matched and re-designed) to be seen, either at the sight of self-contained elements, drawn from one another with a dart, or in the outside building.

The monoblock is more beautiful to be used for prompt implementation of the events, and it is less important that it is more important in the robot. However, there is a lack of handiness when vimir in importantly accessible places, with the development of direct and re-strata during the whole show. To that, when carrying out attestation of workmanship, most often they use a photographic sensor. Easy to understand from the most popular models.

Attachment for visualization of illumination U-116

Vlashtuvannya shche radianskoy rozrobov Yu-116 in the range from 1 to 100 000 lux. It is stored in 2 parts: a selenium photocell and a sweeping galvanometer, which is used for displaying. Take care of the case at the selected viglyad, so that the hopeful banker from the house will be unaware. In front of the robot, the photo-pick is set up from re-converting the forks behind the help.

There are 2 concentric arcs on the scale. The interior is programmed from 0 to 30 lux, the size - from 0 to 100. The photocell is fitted with a light-absorbing nozzle, which can be stored from a non-transparent plastic and opaque ring. It is designated by the letter "K", vimiri with it vibrate at the indicated ranges. Є more 3 filter nozzles: M, R and T. When they are installed parallel to the base nozzle, the range of changes will increase as follows: 10, 100 and 1000 times.

Two buttons on the panel are attached for switching from one scale to the other. If the left button is turned on, it will be displayed in the ranges: 0 - 30, 0 - 300, 0 - 3000, 0 - 30,000 (with installed nozzles). When the right is on: 0 - 100, 0 - 1,000, 0 - 10,000, 0 - 100,000. arrow indicator at the zero position.

The light meter U-117 can be seen from the front without a great number of buttons. To replace the two keys for changing the scales of the settings of the equipment with five buttons for changing the ranges, for the reason that the accuracy of the settings will be adjusted. There are also buttons for micro-setting, the control of the liveness and the zero-setting knob. The life of both models is autonomous - as a galvanic element of the "Krona" type with a force of 9 V. The price of attachments from young sellers is from 6 to 10 thousand rubles.

Yak koristuvat with a lux meter?

It is safe for the photographer to know the required range of visualization, as soon as the singularity of the date:

1. Install the nozzles with the maximum glaze (K and T) on the photoset, turn off the right button, then display the maximum illumination value - 100,000 lux. At the same time, at the same time, the reaction of the imaging shock increases the level (up to 30,000 lux).
2. If the arrow does not collapse, replace the filter with a clear (P) and insert it in the same last: the right button, then the left.
3. For the duration of the day, set up a soft filter (M) and the development of analogous manipulation.
4. Even if the button is pressed, the result will be less than 5 lux, note the basic attachment. K and stop the noise.

If you want to see the value of the area overlap two scales (in the region 5 - 20 sub-scales), it is recommended to start from 5 sub-scales on the internal scale, or from 20 on the basis of the current scale. With the mark on the scales of individual values ​​of the point of the cob to the side.

Remember: the overworld illumination of the selenium photosensor can be integrated into the correctness of the day, so follow the prompted end-of-life.

Testo Luxometers

One of the most popular in Russia is the Testo 540 digital light meter (Nimechchina). The attachment of vikonaniy in one volume, a photocell of integration with the hull, for whom the vikorstanny's performance can be adjusted: an out-of-the-box wiring, which can be stored for a moment, you can use the hand to carry out one.

The shape and dimensions of the device are nagaduє stylish phone... For indication, it is shown that such a display is used, and the keyboard should be replaced by only 3 buttons: on, vibrate the system and activate (CI abo American - foot switch) and save the results. Range of vimіryuvannya: 0 - 100,000 lx or 0 - 93,000 ft.

It’s okay to go for storing in the haunted life. With this additional help, you can see the level of illumination in living rooms, schools, children's kindergartens, greenhouses, facilities for saving cartoons and so far. Getting around the device is borderline simple: by pressing the on button, the system vibrator (tricycle) and - that's it. The result is practical mittvo. To save the result, press the "mode" button.

The digital attachment Testo 545 belongs to the class of professional attachments for enlightening the middle. Svitloprymach vikonaniy okremo from the electronic unit and stay with him as a guide. See a young brother b about the most functional possibilities:

• memory for saving up to 3000 results in vimiriv;
• safeguarding the memory of the 99th month of the year;
• connected to personal computer;
• pobudova large graph of the magnitude of illumination at the boundaries of primacy;
• druku danih on the printer.

Tsey prilad vikoristovutsya in the process of enlightening the day, building, streets, roads and other large masses. The price of the Testo 540 lux meter can be adjusted from the price of the Yu-116 (close to 10 thousand), and the Testo 545 is sold for 35 thousand rubles.

The light meter is one of the available and effective water-hour devices for adjusting the illumination parameters of the object. Yoho vicarious will provide you with a comfortable mind for people like in a vortex situation, as well as in everyday life. Thanks to the support of the statute to help you zorієntuvatisya, you can choose from the necessary options for a reasonable price.

What is the best way to spend a day of illumination? It has been reported that the nasty (or navpaki, zanadto is good) light through the eye slick injected into the brain's work processes. I as a heritage, to the camp of people. Lack of illumination drove, decrease in patriotism, and become drowsy. Zanadto yaskrave svitlo, navpaki, zbudzhuh, when connected to additional resources in the body, winking and developing knowledge.

To carry out the illumination of the working missions at the same time, from the moment to the noise, the pilot of the obstruction, the change - according to the Sanitary Rules (sanitary rules and regulations). Doctors singled out that there was a regular lack of illumination of the victim, a decrease in hospitality, and a decrease in the concentration of respect. Tobto є all change your mind for the harmless vipadku.

The filthy light is injected and is alive and well: roslini, tvarin. Those that grows rotten to grow rotten without light are a fact. Alle the lack of illumination and food injected, so it goes. Tastes: the destruction of growth and development, the decrease in productivity, the loss of mass gain, the destruction of the function of production.

What kind of illumination?

Illumination is the value of the light flow rate up to the area, as it falls. Moreover, the fall is perpendicular to the area itself. Enjoy in suites, lux. One suite is available for one lumen to square meter of surface. Lumen is the unit of light flow. Price for systems of international monitors. In England and America, there are some lumens per foot per square. Abo foot candela. The illumination of the light from the jerel is the force of one candela from the edge of one foot from the surface.

Europe has a standard for the illumination of working applications. The axis of the recommendation is: illumination in the office, it is not necessary to look at other details, but it is close to 300 lux. It’s a working process that lasts a day at a computer or for dressing from reading rooms, it is recommended to cover about 500 lux. Likewise, the illumination is transmitted at the meeting rooms. Not less than 750 lux at the side, they are de-readable and read the technical chair.

Visvitlennya buvaє natural and piece. Dzherelami of natural illumination є, zeros, sun, misyats (more precisely, the illumination of a dream with it), rose to the sky (such a poetic name is vicoristovuyutsya to navigate in the protocols in the form of illumination). Dzherelami piece coverageє, of a kind, form and structure, lamps and lamps, light displays of computers and mobile attachments, screens of televisions too.

Name one of the illumination (luxury), the name of the attachment, and the name of the one - the light meter. A mobile portable attachment for visualization of illumination, the principle of robotics is identical to the photometer.

Potency of light, tap on a photocell, sound like an elec- tron ​​at the contact of the inspector. Fixes for a complete photocell fix conduct an electric strum. The axis is the magnitude of the struma in direct proportion to the illumination of the photocell. Win and be seen on the scale. In analogue lux meters, the scale is graduated in lux, the result is shown in the direction of the arrow.

Infection on the change of analogue to come digital, attach for a vimir of illumination. Stink the result of vimіrіv vivodit on the liquid crystal display. The vimiruval part of the bagatokh is located in the surrounding building and is tied with a nasty attachment. It allows you to spend time at important places. The staff of the set of light filters can be adjusted between each other. At the same time, it is shown that there is a lot of multiplication on the singing performance. Failure of a light meter, but not more than 10% is to blame for GOST.

How to be held in the form of illumination?

The stagnation of any methods of visualization of illumination is uncomfortable without a light meter. Moreover, the rule is to be met: horizontal position... Yogo vstanovlyuyut at the necessary points. Derzhstandards have schemes for rosttashuvannya tsikh points and methods of їkh rozrakhunkіv.

Earlier in Russia, GOST 24940-96 was used for enlightenment. Tse interdepartmental standard in the form of illumination. At the same time, GOST has such an understanding, such as: illumination, average, minimal and maximum illumination, cylindrical illumination, efficiency of natural illumination (KEO), efficiency of spectral performance.

In 2012, Russia has banned the government, the national standard for illumination, GOST R 54944-2012. For all guests, to understand what happened before, to give: emergency illumination, security illumination, robust illumination, reserve illumination, evacuation illumination, evacuation illumination. In both GOSTs, the lectures describe the methods of illumination.

Vimiryuvannya is carried out okremos from piece and natural illumination. With a whole slew of stitches, the thigh did not fall on the butt; Tse will change the result. In addition, as all the necessary information is broken down, on the basis of the results obtained, according to special formulas, the required parameters must be provided, and a general estimate must be made. In order to eliminate the parameters to compare with the standard, and to be careful about those who have enough coverage of the given primacy of the reading.

On the skin type of vimіrіv in the skin prіnіshennі chi dіlyantsі vulytsі remember the okremiy protocol. The estimated protocol is seen in the skin of the skin, and in the whole object. Tsyogo demand "GOST. Vimiryuvannya illumination "maє buti vikonano for the rules.

How much light is needed?

Until the end of the day I show you how colder the light will lower the level of sleepiness, and will reduce the concentration of respect. Explain the process of strangling with short praises (ultraviolet, blue color) melatonin. A hormone that regulates additional rhythms. And as much of the light of the future will be scorched, we will help to fit in with depression. Do not overdo it in the head. And then from one extremes you can spend up to іnshoi, otrimati the disturbed sleep. Visiting with cold light throughout the day, we'll be peaceful. At the same time, if you have enough illumination, you don’t mind napruzhuvati zir abo, navpaki, wry.

Mortals, navpaki, more dimly muffled light of warm tones. Winning a feeling of weakness, as a result of the repair, going to sleep. It is necessary to have a unique kind of bright and bright sleeps of light, especially a cold tone.

Significantly, one-time damage to health rules not to cause serious damage to health. It’s a matter of regular problems because of the deterioration of the functions of the body. Such a ric, like a light only for the first glance, to be built with a dibny. Periodic control over it, in the form of illumination necessary.

The theme of the pulsation of illumination and norms of the illumination parameter is discernible for the year.

How do you manage the pulse rate?

Experiments have confirmed that light will inevitably pour into our health. Weak illumination in the workmanship is a common cause of health problems, decreased concentration, sickness in the psyche, and a decrease in preference.

Overwhelmingly, light, navpaki, is an agile factor and can cause stress.

The most beautiful solution is to ensure the correct coverage, as the guarantee of the optimal performance.

Normal level of illumination is clearly regulated by skin types. For a number of parameters, they have their own norms and rules that are necessary for the nobility.

The whole control function has a sanitary and epidemiological service.

Visibility: who can get it?

The nominal illumination of the numerical rotation is the price of the illumination, going down to the area down to 90 degrees from the size of one single area.

As soon as the light falls down, the illumination parameter changes.

Otrimaniy indicator changes in direct proportion to the guessed vishche kutu.

One vimiru rivnya illumination - luxury. At the same time, there is one suite for one unit of light flux (lumen) per square meter.

If I look at a physical single system, then the only thing in the world of illumination is a photo. In tsomu 1 ph = 10,000 lux.

The parameter of illumination changes in proportion to the strength of the light, so it looks like the dzherel itself. What is given is an object that is illuminated, that is, the lowest is illumination.

For example, the United States and England are one of the only illumination companies. There it is accepted vikoristovuvati "foot-candela". The whole parameter shows the strength of the light, like the one candela, the object on the display is one foot of the light.

Theoretically, there are more than a few types of odinits of vimiriv, ale, zazvychay, stinks are old, not known by the international system of chi є vychayni old of the main parameter (luxury).

Enlightenment of application: basic methods and application

In order to provide a level of illumination, you can choose one from the lower points - a flash meter, an exponometer and an exponometer, a light meter or a photometer.

The head attachment from the group, the main parameter of real illumination (natural piece) is a light meter.

Stinks of analogs and electronic ones. Analogs are not included, they are no longer a rarity.

Yogo can be set up for revision of new buildings:

• vimіryuvannya rіvnya illumination for the hour of attestation (revision) of working missions;
• knowledge of the indicators of illumination and of the correctness of the parameters for the installation of the elements of the illumination;
• control of compliance with the level of illumination with respect to quiet norms;
• analysis of illumination parameters for the conformity to rotor parameters during the period of work carried out from the installation of illumination elements.

The light meter itself is based on a simple principle. A photocell is installed in the middle of the annex. If there is a new direct light flow, in the middle of the conductor element, there will be a straining flow of electronics.

As a result, є the electric strumu winnings. The value of the remaining proportion of the strength of the light, when the photocell is attached to it.

As a rule, the male parameter of the images on the scale of attachments.

Regarding the type of fixation of the control element (sensor), the lux meter is of two types:

• zhorstka fixation of the sensor (to be displayed in the form of a central unit, monoblock);
• with a wine-type sensor, which can be connected behind an additional flexible cable.

For carrying out simple tests, there is enough simple attachment- light meter for monoblock form, without additional options.

Yaksho is required clarification more parameters when carrying out professional training, more beautifully using more folding attachments - with the option of calculating the average parameter and memory.

A great plus is the storage in the luxmeter of special lighting. With this additional help, you can more accurately calculate the parameter of the power of the light, which can be entered from the lighting attachments with different types of color.

Besides, attachment with a wine sensor to show a greater accuracy of vimiryuvan, and even on them there are men who are called officials.

At my own house, the appearance of the RC-display on current models will significantly forgive the process of displaying from the annex.

So just put, like the exposure meter and exposure meter, get stuck in the photographic technique.

Їхн enterprise - fixation of parameters in illumination, exposition and quality. Knowing the magnitude of the number of indicators, the photographer can reach the ideal quality of the photo.

There are two kinds of vistas in front of your room. The stench is calling and internal.

Head of flash meter - Vimіryuvannya rіvnya illumination in the process of photography. As an additional element, the lighting attachment of the impulse type is fixed.

New cameras have a flash meter already installed. Yogo zavdannya - regulation of the drudgery of the photographic sleepers is fallen asleep from the level of illumination.

At the professional studios you will be prompted to pick up a wine-type flushmetry. Їх specialty - explicitness exact systems Indication, building fiksuvati yak fall, and the first view of the promenade of light.

A multimeter (photometer) is a progressive and modern type of flash meter. Yogo plus - the building of the functions of the expo-meter that we have guessed will be attached.

Coefficients of the pulsation of illumination: the day and the norms

It is no secret that all illumination should be given a viprominuyut of an unreasonable illumination, small amount kolyvan. The whole effect of the ghosting of the eyes, ale of yogo action on the health of people, and duzhe suttava.

At the same time, the light is not safe because of the fact that it is impossible to recognize it, but the result of this can be sleepiness, weakness, depression, anxiety in the robot's heart, discomfort, and also the result.

Coefficient of pulsation of illumination is a parameter that adjusts the force of the change in the light flow, so that it can be straightened to one surface of the clockwise passage.

The rate of performance is on the lookout for a simple formula - the maximum illumination parameter in the singing interval of the hour minus the minimum indicator for the same interval of the hour.

Otrymane the number must be distributed to the middle parameter of illumination and multiply by 100%.

Varto vrahuvati, according to the sanitary rules for setting the upper limit on the parameter of the pulse rate.

In the organization of the work organization, the guilt is not guilty of the workmanship for 20%. At the same time, there is a great view of efficiency in the foreman, we have the lowest parameter.

So, for the offi- cials and administrative buddies, they depend on respect, the zorova pratsya is stressed, the efficiency of the pulsation is not guilty of more than 5%.

At the same time, a light stream of pulsations up to 300 Hz is taken into the field, even this frequency parameter simply cannot be absorbed by the human organism and cannot be infused into it.

Coefficient of pulsation: special features of the period

To increase the frequency of the pulsation of illumination, we can quickly forgive і effective fit- Vimirnik of illumination, pulsation and yaskravosti.

Its functionality allows for the following:

• the level of quality of monitors and attachments of piece coverage;
• level of illumination of the room;
• pulsation of illumination of all types of monitors;
• pulsations of light, which appear in the presence of small children.

The principle of the main group of attachments (pulse meter, brightness meter and light meter) is to control the level of light for an additional photo sensor, if it is received by the signal, and the result can be displayed on the RK display.

Luxmeter-Pulsemeter-Yarkomir Ekolayt-02.

In order to make sure that you have a function of pulsation, you can take two paths - to conduct an independent analysis of your speed with a computer program.

Most popular attachments for calculating pulsations - "Ecolight - 01 (02)" and "Lupine". As long as it is necessary to analyze the data on computers, it is possible to use special software - "Ekolait-AP".

The main idea of ​​the annexes for the detection of pulsations is the quality of photocells, the type of battery life and sensitivity.

Maximum pulsation efficiency May light bulbs(The one parameter can be up to 100%). Lamps reheat and luminescent lamps and may have lower pulsation efficiency.

For example, the first rate of pulsation is not more than 25%. At the same time, the price of the light was not very important, but it could also use expensive lamps and might have a high efficiency of pulsation.

Standards of illumination

The current skin type will have its own norm of illumination, and the limit of permissible pulsation efficiency will be established.

For example, for a sales area in a grocery store, the maximum parameter of the pulsation efficiency is 15%, and the level of illumination is 300 lux, for used materials, sports goods and sanitary equipment - 10% and 200 lux, for one used dishes - 20% 200 lx, for primaries - 20% and 300 lx and also.

Apparently, its own standards of illumination are for child cages, living quarters, medical pledges, car washes just.

How to reduce the pulsation of visibility?

In the rest of the rock, it is all the more important to control the pulsation, how to enter from the dzherel illumination.

When the parameters are enforced, all the normalization (reduction) is used.

Implementation of one of the offensive methods:

1. Vikoristannya illumination annexes, scho work out of a changeable strum (the frequency is more than 400 Hz).
2. Installation of a ballast compensating attachment at the svitnik, as well as connecting lamps with zsuvami. For the first lamp, there is a characteristic strum, which is vidsta, and for the other, it is viperdzhalny.
3. Installation of simple svitlnik_v on a different phase (triphase mesh is required).
4. Stagnation of svitilnik_v from EPRA.

The vibration of one of the options, in addition to which it is possible to reach the optimal parameter of the pulsation rate, to lay down the minds of the implementation for the skin of specific types.

Є If the fixtures are not connected to one of the three phases, the installation can be stopped before the lower phases by the foldable devices.

Buy special lighting fixtures from EPRA. Ukhnya perevaga - compliance with sanitary standards. At the same time, it is possible to mount the EPRA as soon as the annexes are ready.

Coefficients of pulsations and standards of illumination: basic documents

The main document, in which all the vimogues are spelled out, are as follows: 52.13330.2011 ).

Win buv voices at 2011 rotsi і є SNIP 23-05-95, de spelled out the keys to the laws of the country and international standards, energy efficiency and technology safety.

The Zvodi rules are of the greatest importance to the efficiency of pulsation and illumination in different types primischen - zhitlovyh, industrial type that huge.

The control of illumination and the level of pulsation of piece illumination is not only necessary for the formal attestation of the workmanship, but rather the planned conversion from the side of the sanitary station.

It is very important for the health of people, and even seeing from the indicators, how to live, can bring to the destruction of self-esteem all the sportsmen who are in the home.

Yak inheritance, the rate of return will decrease, the profitability of the company will decrease and the income will drop.

5 / 5 ( 1 voice)

On the front panel of the vimiryuvach є transfer buttons, that plate with a diagram, which clinks the buttons and attachments, so that you can select the vimiryuvan ranges.

Adjustment of magnetoelectric systems for two scales: top 0-100 and bottom 0-30. On the skin scale, the dots indicate the ear to the range of vimiryuvan: on the 0-100 scale, the point is above the 20 mark, on the 0-30 scale, the point is above the 5 mark. A plug for attaching a selenium photocell was mounted on the bicniy stintsi body of the vimirnik.

The selenium photocell is located in the plastic case and must be connected to the cord with an outlet to ensure the correct polarity of the connection. To reduce the cosine error, attach the attachment to the photocell, store it with naphtha, wicker plastic, light it up, and opaque plastic ring, which has a small folding profile. The attachment is designated by letter K, applied to the її internal bik . This nozzle does not stagnate independently, but at once with one of three: one of the three nozzles, which may cause the designated M, R, T. Expansion of ranges in vimir.

The light meter is graduated without attachments in the main range of vimiriv (5-30 LK; 20-100 LK) ) I can’t take the guesswork out of it, but it is allowed, equal to ± 10%.

The procedure for identifying the meaning of information

Against the tensioned buttons, you must select the most suitable nozzles (or without nozzles) for the best range of vimiryuvan. When the right buttons are pressed, against the application of the most significant ranges of 10, then the scale is 0-100. When the buttons are pressed against the application of the most significant ranges of vimiryuvan, multiples of 30, then the scale is 0-30. The indicated attachment in the pods, behind a scaled scale, is multiplied by the weakening factor, so that the attachments lie down, they freeze, and the indications on the attachments M, P, T.

For example, on the photocells the attachment K and P is installed, the left button is pressed, the arrow shows 10 sub-lines on a scale of 0-30. Vimiryuvana illumination of the road 10 * 100 = 1000 LK.

To remove the correct light meter readings, protect the selenium photocell from the background illumination, as it is not visible to the vibrating nozzles. Also, if the amount of illumination of an unidentified person, repair the image by installing the K, T nozzles on the photocell.

For a quick joke, the range of vimiryuvan, which is shown to be shown in between 20-100 pods on a scale of 0-100 and 5-300, comes in the following order: place the CT nozzles last; Up to P; Until M and with the skin attachment, press the right button from the sprinkler, and then to the left.

Even with the K M nozzles and the push-button pressure, do not reach 5 pods per 0-30 scale; with a photocell.

When illuminated, place the photocell horizontally on the working device, and view the camera, which is also horizontally rotated, to move the photocell, for the most part, if you didn’t use it on the photocell.

When the vimir is finished:

see the photocell from the light meter;

attach the T nozzle to the photocell;

put the photocell in the case.

Dana statty є shifting statti Luxmeter App versus measuring device:
Chi є smartphones suitable for measuring illuminance?

For smartphones there is a free program that will lay down our life. Є free software for lighting technicians. Ale chi means, how can you use a smartphone for visualization?

We will supply food all the more and more often, for which the benefit is obvious. Also, these programs bezkoshtovnі or the cost is not much dear. Bulo b miraculously replace the lux meter, which is fallen from the virobnik and the accuracy, from 100 to 2000 Euro. (Alyekspres is not working and showing sumi navit less than 10 EUR), for a supplement for a smartphone, like and so є may be skinny.

Since it is an accredited lighting laboratory, we can just laugh at the idea of ​​\ u200b \ u200bimaging illumination for an additional smartphone. Tim is not the least, we had a great idea to finish the tsikava, which sponded us to conduct an experiment. In such a rank, we have thought of shukati development programs for new operating systems. We wanted to s'yasuvati, for some of the stench we were able to change in proportion with a light meter from our laboratory.

Apparatus for securing

For the whole test, they were victorious. iPhone models, as well as: Sony, Samsung and Nokia.

Secure program
We have installed the following programs, most of them without a frame:

Standard attachment

We carried out control tests for the additional light meterPRC Krochmann (Model 106e, special model, class A)І, vividly, the attachment of the buv vidkalibrovany.

Vikoristovuvanі dzherela svitla

For the whole test, three different dzherel lights were selected:

· low voltage halogen lamp

· compact luminescent lamp(Color temperature: 2700 K)

· LED (color temperature: 3000 K)

Do not be quickened by the article we have lost only LED dzherelo.

Our test setup

The test was passed in a dark primitive without a piece that is naturally light. For the installed dzherel lights, the illumination on the air was set at 100 lx, 500 lx and 1000 lx (mabut all the same 2000) on a horizontal surface. For the sake of the photometric head of the light meter, the bullet is welded perpendicularly to the axis of the svitnik.

Then, the smartphones themselves have been made use of with small supplements, so the front camera and the sensor of brightness were used by the satellites. The sensor or the frontal camera was removed exactly at the same point, before the photometric head of the luxmeter was removed.

So bully roztashovani all outbuildings, for a blame iPhone s paid supplement"Luxmeter Pro Advanced" is a program for visualizing the illumination of the transmission of light from the surface. For a whole lot of supplements it is possible to complete a lot of nalashtuvan, including tip and dzherel light, go to dzherel light, etc.

So it is with victorious programs that you can calibrate. The calibration was carried out on a preliminary basis to the instructions, and it was 100LK.

Assessment

Before the hour of our test, they sat down, so I would like to calibrate in deyakie dodatkiv and it could be as high as the singing value, without going into the distance. Tse became through those that were crooked with yakim, the value of the boom was great, or the value of 100lx did not get up, but at the end of the day LightMeter by whitegoods for iPhone 5, the value for the calibrated distance is set to a maximum of 34lx.

Vіdhilennya from etalonnyh vіdalonnyh vіdlіvі viskі (reached 113% of Samsung Galaxy S5 with the addition of "Lux Light Meter" from Geogreenapps). When the reference value was set to 500 lux, a value of 1.063 lux was displayed on the smartphone display. Naynizhche vіdhilennya in vіdskotki (3%) bulo is fixed with the victorian iPhone 5 and programs " LightMeter by whitegoods " ... When the reference value is set to 500 lux, the whole smartphone shows 484 lux. However, we can’t run a single application, but the message of a smartphone with a specific program will always show the correct value. When the illumination was set to 100lx, and when the display was installed on the same smartphone, the display reached 89% and the settings were shown at 11lx.

We were given a tendency to see a tendency, which means that it is displayed on the outbuildings of Sony, Samsung and Nokia. iP hone the value is displayed lower than the standard values. Average display of the reference value, which is displayed in all programs on Android smartphones and on Windows phones Phone , boules in the middle by 60% of the standard values.

Average visualization of all meanings iPhone it was 60% lower than the standard values. We also remembered that the development programs installed on smartphones from Samsung and Sony showed close values. Obviously, in these models, a sensory sensor, not a camera, is used for visualization.

In deyakim Samsung models you can switch to the mode engineering menu- for an additional set of combination keys * # 0 * #. Vibrating the menu item "Light sensor", you can learn about the illumination without installing programs. So we'll get the program set up for a whole lot of problems. Tim is not the least, all of the values, which are represented by multiple outbuildings, are also seen from 37% to 113% of the reference value. Galactica Luxmeter "and" LightMeter by whitegoods ". It’s a pity, і here we were cheated on. Diagram showing how many smartphones, like testuvals, showed absolutely different results in different ways.

Mi podozryumo, as the cause of the chicks є vikorystannya vіdminnyh one of one component, but koristuvach doesn’t help with the popped vikorystannі, but it will become smudged in case of average porosity.

How do you get the dynamism of the high-speed output from the reference value?

As soon as you start a victorious smartphone with one and the same add-on, you can wait until you can get it right, if you already know that you can see the standard value.

Do you want to see the same thing, do you see meaning on the yak? In order to be able to see it on the power supply chain, we carried out an update of illumination at 10 lx, 100 lx, 1000 lx and 10,000 lx for an additional iPhone 5, which was installed on optical lavas in our black room. The growth of quality can be set even more precisely by regulating the appearance between the dash of light and catch. Yak dzherelo viprominuvannya know vikorystovyvsya svitlodіne dzherelo light with a temperature of 3000 K.

Many tests saw two different programs shown. As shown, the value of the data is seen one form of one - in some cases it is up to 358% (the value is from 12 lx to 55 lx with a reference value of 100 lx), which are susceptible to at least some of these

With victorian programs " Galactica Luxmeter180% REF at 10 Lux and 50% lower REF at 10,000 Lux.

With victorian programs " LightMeter by whitegoods displayed for 10 lux. With a reference value of 100, the visibility slipped 88% down the side, and with 10,000 lux, 59%. The meaning of all the applied boules is so meaningfully lower. For all the meanings, the boule is shown as the lowest.

In general, we vyyavili vyyavili, so vimіryuvannya carried out for an additional front and back chamber show the value. Do not show 0 lx for the duration of the program until the end of the program, do not use any light on the camera, and it is closed with a dummy plug.

Visnovok

The results are to show that you may have less to do with the help professional possession... It is equipped with a calibrated sensor, which is a guarantor that the assessment of illumination will be carried out according to the sensitivity of the human eye.

In addition, let me allow you to conduct an assessment of the illumination of the fallow from the bottom of the exchange. Smartphones can’t destroy neither one nor the other, nor can the stench be able to show its function.

Unimportant to those who store the store, how the stench can replace the professional attachments, the odds in their supplements є різні smart functions type of caliber, ale colibruvannya is not allowed to stand exact values... And if it is worthwhile, then all one is recognized as a result of the loss of life. Navigate with the victorian of the same program and the identical smartphones to come up with the results of the same.

To that, it's a pity, let's program marne for the sake of it - just to navigate in order to correct the information about illumination.
