 How to distinguish a good LED panel light

  1. 南粤36选7开奖结果今天look at structure

    The panel light is made of Alu frame,light source,PCB board,diffuser plate,light guide plate,EVA robber Mat,back plate(for others,please see below structure),these are the most important components.

  2. look at the alu frame

    The best is to use Al6063,good Aluminum keeps good heat dissipation,the surface temperature of our panel light is lower than 35°

  4. look at the light guide plate--the most important part

    light guide plate has 3 different materials,they are pc(polycarbonate),pmma(polymethyl methacrylate) and ps(polystyrene),because pc is expensive,so most light guide plate is used by optical pmma.another important thing is,the thickness of pmma,the best is 3mm.these 2 factors make panel light uniform, durable, not easy yellowing, no dark area,and the light spot is printed by uv screen printing.some factories will make the light guide plate 2mm or delete light guide plate to reduce cost.the result is the light is not uniformity.

    when the panel light is finished,it will need at least 4-6 hours aging-test,the testing should include voltage partition testing,high and low voltage testing,switch on-off testing.etc
