Methods for measuring on a light stream

Title: Lightening

For yes, you feel comfortable in the flock at any time of the day, and more importantly, you will achieve not only high-quality natural, but also artificial lightening. It is difficult to compare it with the quality of natural light, but you can still experience everything. Tova iziskva yes you know how yes calculate the stream of light.

Why is it calculating the illumination?

Regardless of how the illuminator and the lamp crawled into it, whether it was degrading or calculating the lightening separately for each flock, for which the foreseeing of the use of the lamp, lamp, bloom and kind of cover. By itself, by correctly placing the bodies on the illumination in the correct amount, it is still possible and the effect is not comprehended. Item is needed for:

1. Convenient presto in the flock and abdomen.
2. Work for the audience apparatus for a person, depending on the task, which is performed.
3. Exceptions for painting on the viewer's witticism.

In the process of evaluation bright stream all will be taken into account:

• Illuminance, measured in lumens. Tosi parameter is considered as nai-important, ty kato influencing the top of the stamina on the light stream, which is distributing it into flocks.
• Brightness, the main meter of the apartment.
• Svetlinen intensity in candela.

Difference between natural and artificial lightening

Nay - kindly lightening for the eyes of the choveshkite is natural, that is, the day, the sutri, the evening, inclusive of tova, somehow and two from the slyntseto ass cloud.The light from the lampite is artificial, forming as a result of not being converted into electrical energy in an electromagnetic radiation. The key task is when calculating the brightening of the stainoto e and ce closer from the bushy light (regardless of the type of lamp used) to the natural light.

Calculating methods

Necessary and sufficient light flow can be counted, cato se using a single method:

1. Specific power. Izpolzva ce for the assessment of general clarification. For yes, calculate the total power, and it is necessary to multiply the standard data (specific power) by area per room. For yes, determine the correct standard indicator, and it is necessary to take everything into account: it is visible on the lamp, it is intended for the room, the distribution is on the lamp according to the wall and tavan. In this case, the trace of the calculation of ce will determine the configuration and conditions for clarification, which is more convenient and more convenient for the person.
2. Percentage on candidacy. This is where the beginning determines the location on the source to the light, which is the report of the configuration on the room and the possibility of reflecting or absorbing the light. The predicted formula is multiplied by the standard for illuminance by area per room, by the coefficient for safety and by the minimum coefficient for illuminance. All goods are divided into broken lamps, multiplying between si and coefficient on the use of the light stream.
3. Dot. Tosi method is considered suitable for any flock, maybe yes, it was used for depicting on the svetlina on the streets. For yes, they will receive the result, evaluating the illumination at separate points, above which the light falls. In this case, lighting devices can be set up as you wish.Evaluation of this izvarshva in the key for the consumer of the point. Tazi technique is especially relevant in the premises, it is darkly covered along the walls and the configuration is complicated.

These methods are not very difficult to implement, but all packs are much simpler, the same method is presented in full.

The choice of method for calculation depends, along with others, on the type of lamp used. back kjm sdzharzhanieto ↑

Simple method for calculation

The proposed option for calculating e is suitable for a flock with the correct shape - square or right-handed. Illumination is measured in Lux (Lx), calculated on a parameter for a light stream. It also consists of two stages:

1. Calculated for incompetence, the stream is light, which is necessary for illuminating a room with a defined quadrature.
2. Determination of the broy on the light source.

On parvata st'pka izchislyavame necessary parameters for the light flow for the room. Calculation is a perversion according to the formula:

Svp = X * Y * Z, kadeto

X is a normative indicator for illuminance per room. Can you please put these standards on the list by value.

Y e area per flock in m².

Z is the coefficient for the correction, reporting a high score on tavanite. Taka che for tavani with a height of up to 2.7 m tosi parameter = 1, for 2.7-3 - indicator 1.2, for rooms with tavan 3-3.5 m - 1.5, for a flock over 3.5 - coefficient 2 ...

Standards for rooms in kashchat:

1. Corridor, entre — 50-75 Lx.
2. Keeler - 50 Lx.
3. Kitchen - 150 Lx.
4. All hall – 150 Lx.
5. Children's flock — 200 Lx.
6. Sauna – 50 Lk.
7. Closet or library - 300 Lx.
8. Stulba — 20 Lk.
9. Sauna, swimming pool - 100 Lx.

Kolko Svetlina, you need it, depend on the destination, it’s for the flock

Repeat the next step to help you determine whether you are looking for a light source, in this case, use an LED lamp.Approximate indicators, according to which you can move:

Lampate power, WClear stream, Lm3–4250–3004–6300–4506–8450–6008–10600–90010–12900–110012–141100–125014–161250–1400

Just leave it alone and calculate the result. For the basin, the digit is intact, obtained at the first stage, the ripple is even divided into parameters into a light stream, for all from the lampata. As a result, the tova received the need for a broken lamp.

Try on for

Initial data:

1. Children's flock with an area of ​​25 sq. m.
2. Visochina on tavana - 3 m.
3. It is designed for 8 W lamps.

First step:

200(X)*25(Y)*1.2(Z)=6000lm

Lamp, which is still used, ca 10 W, luminous flux, declared by the manufacturer, e 900 lm. That is, the required amount is 6000/900 = 6.66. It was closed by giving an armor for 7 lamps.

If you use lighting lamps with a lower power, for example 4 W, put them on the wall along the perimeter, then shake 13 flasks. Comrade, direct the distribution to Svetlinat evenly. There is a ripple here and you will take a look at the used lamp, its design and interior design.

The quality for clarification is especially important for children's flock

Similar calculations can even be sent for lamps with a lit flask and fluorescent lamps, the table is even more helpful in calculating:

Power for a lamp with a pressed switch, WLL power, WLight stream, Lm205–72504010–124006015–167007518–2090010025–30120015040–501800

Izchislyavame for a single and eating flock. Lampite with a litter box you need from:

1. At 60 W - 6000/700 \u003d 8.57, round the hill - 9 br.
2. At 75 W - 6000/900 \u003d 6.66, round the hill - 7 br.
3. For 100 W - 6000/1200 = 5 pcs.

Fluorescent lamps:

• 10-12 W - 6000/400 = 15 br.
• 15-16 W - 6000/700 \u003d 8.57, round 9 bros.
• 18-20 W - 6000/900 = 6.66, round up 7 bros.

These calculations are based on the norm on the SNiP svetskite, but the experts are multiplied by the result with a coefficient of 1.5-2, depending on the decoration on the flocks and interior solutions.

Hello! For yes, do not forget to own a system, you can use special devices, such as Cromatest. Tova is a device for helping and measuring the intensity of light. Another device is a light meter, whose main component is a selenium photocell. You can do this and that you can contact a specialized company that will help you in calculating this rate.

How did tryabva and this ima foresee when calculating?

Go ahead and correct the calculations, tryabva and decide which lamp is still crawling. Check out the real options for the lamps:

1. With a hot chin.
2. Halogen.
3. Luminescent: compact or linear.
4. LED: lamps, ribbons or spotlights. In the case of an LED strip, the density of the LED is important. You can sort out the tosi parameters, which you can carefully examine the tape.

You can see that there is a stronger influence on the light source, the main thing is the diffusion of the light on the light, the softness on the use. Everything from the source to the light stream is characterized with parameters that can be used for measuring the light stream. Specifically:

• Power This is the amount of energy, some consumer lampata, in W.
• Light stream. Somehow it’s undeniable, the amount of goods is bright, some of it is good.
• Heating at a low temperature - from behind the lamps with a burner and a halogen lamp.
• Color rendering. These parameters include: color temperature and nuance. Parviyat element e from red to blue (1800-16000 Kelvin).Sennikat for the time of the lamp is fuel or cold. Toy e tosi, which determines the general perception of lightening.

Color rendering on various types of lamps:

1. A lamp with a hot plug - from 2200 to 3000 Kelvin (K).
2. Halogen - 3000 K.
3. Fluorescent lamp (fuel light) - 3000K.
4. Fluorescent lamp (byala svetlina) - 3500 K.
5. Daytime fluorescent lamp - 5600-7000K.

Important! Kolkoto low and color temperature, sensible close to chervenoto, kolko more, sensible close to blue.

Two more important parameters are the light flow and the light efficiency. The first is the amount of light, some kind of lamp is radiant, the second is the ratio of light to the flow of power - lm / W, that is, it is sharply efficient and economical.

The formula for calculating the light flux

When choosing for a specific lamp and altering it for calculations, it is important and all take into account the foresight factor:

• Location on the light bar. Option sat tavan or wall.
• Mounting height for wall mounting.
• Transparency on the nuance and presence on the decorative elements on top.
• Posoka on the light: on the mountain, over, stretch.
• Blossom on the wall, furniture: light reflecting light, tmnata absorber.

Inaccuracies and sins: how do you communicate?

Difficulties arise, sometimes in time for planned repairs, some lamps will be replaced with others, lamps will be replaced, a new cover of the mounter on the tavan and wall. Vsichko tova influencing the top of the calculation. The main problem is that the reflection coefficient on the surface is not all foreseeable. Painted on the light stream is influenced by:

1. Darken tapeti.
2. Laminate, linoleum, dark, broken off before.
3. Okchen or open tavan, negovyat look and reflecting ability.

All these points are connected with general lightening, thy cato locally, for example, in the work area on the bureau, and it is quite bright. Tova e is disassembled, ty kato in taki zoni nay-chesto montirat separate lighting devices.

For yes, don’t be mistaken, tryabva, yes, Ima foresaw how they reflect, they all bloom. Such white surfaces are reflective with 70%, others are light with 50%, blue - 30%, black - 0%.

Often, when calculating SNiP, this will be taken as a starting point, but do not take away that these developments were still in Soviet times. This is the beginning, in that moment, nyamashe is timely from the source to the light, they repeat the moment - nyamashe is especially grizha for comfort in standing in the flock and standing in the eyes.

Do not take away that there are a lot of lamps, togawa you can make technium broy, especially as you mount your own prevklyuchvatel for any group of clarification.

It’s not difficult to calculate the stream of light, but it’s important to foresee a lot of points: see on the lampata, bloom on the tavana, groan, hearth, dori syankata on the furniture. It’s important to remember that it’s better and better to find sources for light, which can and will be controlled, broken off by economics.
