側發(fā)光面板燈和背發(fā)光面板燈的區(qū)別

1、 Advantage of our Panel Light We will compare this two kinds of lighting from: 1.Thickness 2.Heat dissipation 3.Diffuser 4.Chip Chip (PCB) stick in the bottom of the panel Lighting view Beam angle of the SMD 3014 is 120 degrees, the red point in the picture is the lighting cross point of two chips.

2、Diffuser should be lower than the red point, so that the lighting mix effect is good enough, and no dark point in the panel Thickness of edge lighting is only 15mm, because all the chips are stick on the edge of the panel (not in the back side of the panel) Light emitting of the edge panel is : 30%

3、of light should be reflect by plate (back part) to diffuser, it will loss some luminous of each chip (see the red line), it will lost 20% of luminous compare to the direct lighting Back side Front side Good heat dissipation will help to reduce the luminous degradation and extent lifespan of products

4、 Big heat dissipation area, the whole back part is the heat dissipation, (effective heat dissipation is base on the size of the heat dissipation area), heat dissipation area of direct lighting is much bigger than edge lighting) Edge lighting with narrow heat dissipation area, only the edge part is the heat dissipation. So many chip crowded in narrow edge, it is much heat than direct li
