LED ceiling light engineering application knowledge

First, the LED ceiling light fixture spacing and the number of lamps required for lighting are calculated as follows:

1) £=2m, L=2m, work = 2m. Illumination height = 25 × the distance of the luminaire from the wall, that is, the illuminating height is 25 times the distance of the luminaire from the wall.

2) The illumination power density requirement is l~5W/rri2. Total lamp power = area of ​​the illuminated surface × (1~5). Number of lamps = total lamp power / single lamp power.

Second, the installation notes

1) The position where the luminaire is installed must have sufficient capacity to withstand 10 times the quality of the drive.

2) The working power of the luminaire is AC, should be away from the easy access of the crowd, and the grounding of the luminaire must be done.

3) The cable connector is waterproof and moisture-proof. When installing, tighten the fixing screw on the connector. Check that the female end of the connector has a waterproof rubber ring. This rubber ring can ensure the connector has good waterproof performance.

4) Pay attention to the connection between the power cable and the signal cable. If the signal cable is connected to the mains, it will cause the lamp to burn out. Since the power of the luminaire is relatively large, the appropriate power supply line should be selected according to the actual power when the power cord is laid, and the power supply should be separated.

Proper installation and use of LED ceiling lights is the first step to ensure safety.
