Led flat panel lamp installation method 1 there are embedded LED flat panel lamp, ceiling type, hanging three installation methods, the first to determine which installation mode is. 2, prepare sharp nose pliers, welding, AB glue, multimeter, etc.

Embedded installation method: suitable for integrated ceiling installation, this installation method is often used in offices, stores, kitchen rooms and other occasions, but also the most common installation method, first remove a ceiling, put the driver of the LED panel lamp on the side of the ceiling, and then connect the power cord, and then put the board lights above, the installation method is relatively simple.

What is the structure of LED flat panel lamp?

1. LED flat lamp, including aluminum alloy shell (radiator and lamp slot), LED lamp strip, diffusion plate, light guide plate, reflector or reflective film and rear cover.

2, led panel lamp is composed of the following components: ① rear cover plate this rear cover plate is mainly used to seal the lamp body, for metal aluminum material, generally with 1060 aluminum, the overall texture is strong visually, because it is aluminum, it can also play the role of heat dissipation.

3. The design of LED panel lamp is unique. After passing through the light guide plate with high light transmittance, the light forms a uniform plane luminous effect, which has good illuminance uniformity, soft light, comfortable and bright, and can effectively relieve eye fatigue.
