How to calculate the room illumination - 99 photos of the

Without artificial sources of lighting in the modern world simply can not do. They create comfort and allow you to use the room in the dark.

Not everyone knows that there are certain standards for calculating the required amount of light in a particular room. Many people make a mistake when limited to one source.

As a rule, it is the overhead light from a large chandelier or lamp, this is wrong at least because it creates a heavy strain on the eyes. Let's figure out how to calculate the illumination of the room.

The need for lighting

In addition to being able to comfortably move around the room and work, after the sun sets below the horizon, light is also necessary for our health. Due to insufficient lighting, problems such as:

  • Great strain on the eyes and deterioration of the functioning of the visual organ. May lead to a noticeable deterioration of vision, consultation with an ophthalmologist and wearing glasses is required;
  • Deterioration of general well-being;
  • Excessive irritability;
  • Decreased immunity and increased cases of colds;
  • Sleep disturbance;
  • Decreased performance;
  • Mood impairment.

You should also pay attention to the fact that the greatest negative impact will be on children, because they are hard to resist external influences.

Lighting is very important, in addition to the interior, it affects the person. That is why it is important to know how to calculate the required number of light sources.

Types of light sources

Starting calculations, it is necessary to find out what are the sources of light. With natural light everything is clear - we can not affect it, except when we buy a house or apartment.

We can take into account at what time of day the room will be filled with light as much as possible, and at what time it will be impossible to do without lamps. Artificial light sources are lamps, chandeliers, floor lamps, which are familiar to us all. They use different types of lamps:

  • Incandescent lamp (with tungsten base), power from 20 to 200 W;
  • LEDs (lamps and ribbons), power from 2 to 30 W;
  • Fluorescent, power from 5 to 80 watts;
  • Halogen;
  • Neon

The power of these lamps is comparable to each other with different energy consumption, that is, LED lamps or lamps will be the most economical, despite the fact that they have a rather long service life.

Artificial light sources are used to create 2 types of lighting:

  • General - a large lamp or chandelier, located under the ceiling and illuminating the whole room;
  • Combined - the whole system of small llamas and lamps, which provides room zoning, while providing different power and intensity of light.

Work areas are lit much more than rest areas.

Thus, to calculate the illumination it is necessary to take into account the power, location and intensity of the light sources.

Illumination calculation

Examples of the calculation of lighting can be very diverse, try to understand how exactly the process occurs.

So, the first thing you should know that when calculating the principle of rounding fractions is used (up).

For example, it will look like this. If, in the end, a value of 37 W is obtained, then it would be better to take not 1 light bulb for 30 W, but two for 25 W.

It should also be noted that the shades that prevail in the room have a large role. If there are many dark colors, it is best to use bright lights.

220-How to calculate illumination

To calculate specific values, it is necessary to use the spot formula: N = (S * W) / P, where N is the number of luminaires, S is the area of ​​the room in m2, W is the power of the lamps, which will create optimal lighting W / m2; P - power of 1 luminaire.

The values ​​obtained may fluctuate, but they will be as close as possible to the optimal number of lamps.
