Well-equipped lighting is not only about the health of your eyes, but also the comfort in the room. For such purposes, it is important to make an accurate calculation of the illumination of the room with LED lamps, since they are today an alternative light source.

In order to evaluate the lighting, they use the data of the intensity of light, its brightness and illumination. The physical value of illumination is indicated in lumens and is necessarily used in the calculation formulas.

We will analyze the instructions using the example of a room with dimensions of 12 sq. m. It is important to note that this room is divided into three zones. Place the main lamp in the center of the ceiling. The working area will be illuminated by LED strips. This option is considered ideal as additional lighting.

Advice! Using LED bulbs, you will be able to create uniform illumination throughout the entire area of ​​the room.

Initial data:

• SNIP norm for a given lighting area is 150 Lux;
• room area 12 sq. m;

Let's get down to calculations.

1. We take both of these values ​​and multiply with each other, it turns out 1800 Lux. This indicator will provide uniform and full illumination of the entire room.
2. Now we find the required power of the luminaires, if 1 Watt of the luminaire produces 86 lux of light.
3. We determine the sum of the powers of all lamps by the division method. For this: 1800/86 = 20.93 W.
4. Round this value and add three more units to it. The final value is 24 watts.
5. Now we purchase lamps (4 x 4 W, 1 x 9 W). This number of fixtures will be enough to place them evenly on the ceiling and create cozy lighting for the entire room. Remember, the most powerful LED should be located in the center of the ceiling.

LED strip: do you need a calculation?

Typically, LED strips are used for individual cases, most often as a backlight. In this case, illumination calculations are not required, since one tape is able to provide the required area with a good luminous flux.

Most often, the comfort of lighting depends on what color the lamp is selected. For example, green, red and blue bulbs are suitable for darkened areas in a room. White bulbs are perfect for spacious rooms.

If you need to illuminate a large space with LED-type strips, you can use programs on the Internet, which in a few minutes will help you calculate the number of such lamps.

Spot LEDs: Semi-Experienced Calculation Method

Depending on the requirements set for the premises in the SNIP, accurate calculations of the power and the number of required bulbs are not always used. Before using them, you need to decide on the purpose of lighting, where it will be located.

For an independent method of determination, only the value of the force flux is useful to you. Such a parameter is often included in the instructions for the device. If such information is not provided, it is possible to determine independently, given that a standard 100 W incandescent lamp transmits a luminous flux of up to 1200 lm. So we need an LED light bulb with a need for 9 watts, it burns with the same brightness as a traditional light bulb. Nevertheless, you can choose luminaires with a certain power without any calculations.

Technical characteristics of LED luminaires

Light emitting diodes have become popular due to their many positive characteristics. Such funds have:

Important! When making a purchase of an LED lamp, be sure to pay attention to the first four characteristics. Operation efficiency depends on it.LED lighting.

The calculation of lighting with LED lamps is often done using a formula. For information on how to get the exact value, see our
