In general, the brightness of LED lights depends on the size of the interior of the house and the height of the ground.

Under normal circumstances, LED20W may illuminate an area of 20-30m. Usually, the height of the lamp and the ground, the illumination angle of the lamp, and the light output angle will all have a certain impact on the brightness of the LED lamp.

First of all, the LED light is mainly made of light-emitting diodes and other materials as the light source. Generally, the semiconductor LED can be fixed on the bracket by using materials such as silver glue or white glue, and then the silver wire or gold wire is connected to the chip and the circuit board, and epoxy resin is used around it. Resin sealed, can play a certain protective role.

It is recommended that in the process of using led lights, it is necessary to regularly check whether the lamps, lines and other materials are abnormal, and repair them in time to avoid danger.
