Industrial lighting rapid estimation method
If time permits and computer lighting software can complete indoor lighting calculations and lighting. When there is no computer at hand and the time is urgent, the following quick estimation method can be used.
1 The central speed estimation method assumes the following assumptions:
1. The maintenance lumen value irradiated on the industrial plane is half the lumen of the new light source in the new luminaire;
2. The size of the irradiated room is general, the reflection coefficient of the room surface is normal, and the dust in the room is normal (a room of a general size means the height MH'J from the working plane to the bottom of the lamp, in the room Half the minimum size);
3. For a given room, only one type of lamp is used (when the working plane is at a height of M greater than 6 meters at the bottom of the lamp, a high hanging lamp can be used. When MH/J is 6 meters, a low hanging lamp can be used).
calculation process:
1. Find the illuminance value A of the application site from the IES Industrial Lighting Recommended Value Table of the North American Lighting Engineering Society;
2. Obtain the lumen value B of the light source from the light source supplier;
3, the luminous flux of the rated light source is multiplied by 0.5 to maintain the lumen C;
4, the number of lamps N =
5, lamp interval S =
6. When using high suspension lamps, the lamp interval S is greater than the suspension height; or when using low suspension lamps, the lamp interval S is greater than 1.5 times the suspension height; then the lamp interval
If S is too large, a light source with a low power level should be selected and the third step should be repeated until the lamp interval S meets the requirements;
7, choose a suitable high suspension or low suspension lamps.
Industrial lighting cloth lamp principle
The luminaire shall be extended from the middle to the boundary. When the rows or columns of the luminaire are odd, there should be one row or column of luminaires on the centerline. When the luminaire row or column is even, the distance from the centerline to the centerline is the distance between the lamps. It should be half the lamp interval S. The distance from the nearest wall to the wall is less than or equal to 0.5S, as shown in the figure.
