Problems that need to be paid attention to in the design and production process of LED clean panel lights
1. The thermally conductive adhesive needs to be as thin as possible, and a self-viscous thermally conductive adhesive can be used, otherwise it will affect the thermal conductivity.
2. The selection of diffuser plates. Now many flat-panel lamps on the market generally choose a diffuser plate with a smooth surface and a matte surface. This diffuser plate has a disadvantage. In the long-term use, the dust will enter the lamp body through various ways, which will cause the lamps and lanterns to have dense bright spots.
In the early days, some people used a double-sided diffusion diffuser. This diffuser has good light guiding effect and low static electricity, which can avoid the bright spot effect of dust entering the lamp body, but the light transmittance of this diffuser is only 85-88%. , whether to choose it depends on the meaning of everyone's own design.
3. In the selection of LED lamps, try to choose lamps with high efficiency, because the side-emitting flat panel lamps have limitations in heat dissipation and luminous flux output. If the power is large, the heat dissipation will be affected, and the light efficiency is low.
4. Try not to glue the light-entering surface when sticking the reflective paper, the glue will absorb light, and it is easy to produce bright edges on the light-entering surface, but a large area of the light guide plate needs to be glued a little, otherwise there will be shadow stripes, because the reflective paper does not This is the case when it is glued tightly and loosened and warped in the lamp body.
