The structure of the LED panel light source mainly includes the following materials.
1. Aluminum frame
Appearance structure, and main structure of LED heat dissipation - generally use AL6063, aluminum extrusion dies, low initial cost input, beautiful surface treatment, good heat dissipation effect, some manufacturers started to make die-casting frames, so IP rating can be made higher, and the sealing is better, the overall appearance is beautiful, but the cost of the initial investment in the mold is higher.
2. Diffusion plate
The light of the light guide plate is evenly dispersed, and the function of shielding the mesh point is also used. The diffusion plate generally uses acrylic or 2.0 material, and the cost of the acrylic is lower and the light transmittance is slightly higher than that of the PC. The acrylic is brittle and resistant to aging. The performance is weak, the price of the PC is slightly expensive, but the anti-aging performance is strong.
3. Light guide plate
The side of ultra slim LED panel light is deflected by the dot refraction to change the angle of the light. The light guide plate is the heart of the flat lamp. The dot design is very important. The dot design is not good, and the overall light effect seen is very poor.
4. Reflective paper
Reflecting the residual light on the back of the light guide - typically RW250.
5. Rear cover
Sealed light body - generally AL aluminum, the overall texture is strong and can play a little heat dissipation.
