Different from other LED lights applications, such as LED tubes, LED bulbs, LED panels did not follow the traditional appearance design. In fact, they are derivatives from LED backlighting technology. Pushing the boundaries of traditional design concept made LED panel lights fully develop their own advantages and wide spread all over the world.
LED panels can emit even rays, no glares, more delicate structures, very popular in offices, hospitals, luxury hotels and some other high-end leisure and entertainment. Their elegant appearances made them the No.1 for lighitng designers or interior designers. This article will give a small talk about the basic construction of LED panels.
Aluminum frames:
Aluminum frames are the main cooing sections for LED panel lights, simple but elegant. The most commonly used model for panel frames is ZY0907, which costs much less in metal mold and stamping. The die-casting aluminum frames can be designed into different IP levels (IP67 tops).
LED lighting sources:
The normally used LED chips for LED panel lights are 3528 (35mm x 28mm), 3014, and 5060. Here panel manufacturers have to do some tradeoff. 3014 and 5060 are relatively cheap but with poor lighting efficiency. Most of manufacturers prefer to use 3528, not for a good lighting efficiency but the designs of light grids is much easier for them compare with 3014 and 5060.
LED light guide plate (LGP):
LGP is a key design point for LED panels. The working principle is guiding the light (generated by side mounted LED chips) thought the LGP evenly. A poorly-designed LGP will cause an uneven light distribution. Most of the light will concentrate on the center while other areas are much darker. Even worse, the entire panel presents bright-and-mark streaks, which is very ugly. In order to increase the lighting efficiency, designers should create a competent LGP. The next factor needed to be considerate is plate quality. However, designers would not pay much attention on this part, since the luminousness of different plates only impacts very tiny influences on total effects. Generally, small sized LED companies prefer to use finished plates from other factories rather than design and produce their own LGPs. By doing so, they can save a large amount of money.
