The efficiency of light emission in the apartment should be different. If in any room the illumination will be equally bright directional or diffused on the contrary the level of comfort is considerably reduced.
The rules of lighting
Therefore, in the premises of various purpose SNiP provides several levels of illumination
The area of a room and its height is a key factor in determining a sufficient brightness of light. Much depends on the type of lighting the key light the local functional mood lighting. The standards specify different levels of light for certain rooms.
When you create a functional lighting system, the lamp needs to emit more bright light. Mood lighting requires installation of lamps of low efficiency. The named indicators light suitable for homes high 25-3 m.
The use of led emitters you should consider their location taking into account the main parameter luminous flux. The brighter the radiation of lamps, the farther they are from each other.
To cover the entire area of the room or a separate area is recommended to calculate the appropriate number of bulbs.
Uniform ceiling light is available through the installation of different types of lighting elements. You can select different combinations of the Central lamp chandelier and spot emitters mounted in various configurations a few ceiling of the instrument main light and decorative light spot emitters in the right quantity and with suitable characteristics to be used in the organization of the main light without the use of chandeliers.
The overall intensity of the illumination lamps for rooms of various purpose is defined as
The last of these parameters depends on the installation height of the luminaires and the reflectivity of different surfaces of walls ceilings floor. For housing but only with the installation of the lamps based on diodes, the figure is 11.
The brightness levels
As an example, consider the calculation of led lighting child
F = 200611= 1 320 LM.
Accordingly, in such conditions it is necessary to use emitters which are characterized by the luminous flux of the desired value below in the aggregate it was possible to obtain a value of 1 320 lumens.
There are different formulas for calculating number of lamps and appliances. A lot depends on their type. For example, in point models usually have only one light source respectively to calculate the number of such devices need to divide the total illuminance f the figure of the luminous flux of one emitter.
If there is another task is to determine how many fixtures have multiple bulbs, it is recommended to apply the following formula
In the result, it is possible to accurately calculate the desired level of illumination and find out how to install lighting fixtures. In any case it is always better to be guided by the estimated data than to illuminate the eye.
You have to consider the type of used bulbs. They can vary in base of the threaded pin color temperature from warm to cool colors power.
In particular, the diode emitters for the home are characterized by a small load on the network from 3 to 15 watts. This is enough to provide bright light for living spaces.
Thus the number of devices will depend on the overall room lighting. But other than that should be taken into account parameters of lamp color temperature luminous flux power. To obtain uniform illumination using led fixtures need to be guided by the calculations, otherwise some parts of the room can be well lit while others too bright.
You can choose any of the existing lighting schemes. The most commonly used options with chandelier and spot lighting without the main lighting device light provide functional spotlights.
