What are the structural composition and materials of high-quality LED panel lights?

1. Aluminum frame

 The appearance structure and the main structure of LED heat dissipation-generally use AL6063, aluminum extrusion mold, low initial cost, beautiful surface treatment, and good heat dissipation effect. I went to the exhibition a few days ago and found that some manufacturers started to make die-cast frames, so the IP level It can be made higher, and the sealing is better, and the overall appearance is beautiful, but the investment in the mold in the early stage is relatively expensive.

2. Diffusion plate

Disperse the light of the light guide plate uniformly, and also play a role in blocking the dots-the diffuser generally uses acrylic 2.0 plate or PC material. The cost of acrylic is lower and the light transmittance is slightly higher than that of PC. Acrylic is brittle and anti-aging The performance is weak, the price of PC is slightly expensive, but the anti-aging performance is strong. After the diffuser is installed, the dots cannot be seen, and the light transmittance should be around 90%. The light transmittance of acrylic is 92%, and that of PC is 88%. You can choose the diffuser material according to your needs. Generally, acrylic material is used.

3. Light guide plate

The side LED light is refracted through the dots to change the angle of light to diffuse out-the light guide plate is the heart of the flat light. The dot design is very important. If the dot design is not good, the overall light effect seen is very poor, usually 1. The middle is bright, The two sides are dark 2. The light side has a bright side and the middle is dark. 3. From different angles, the overall brightness is inconsistent. 4. Local dark areas are obvious. A large part of the light effect of the light guide plate is in the design of the dots, followed by the selection of the plate, the test light transmittance is high, and the light efficiency is high, then you can choose.

5. Rear cover

Sealed lamp body-generally AL aluminum, with strong overall texture, and can play a certain role in heat dissipation

6. LED light source

 2835 is generally used and some people use 5050, 2835 light source, which has high luminous efficiency and strong versatility.

7. Drive power

Lamp driver-power supply mode 1. Directly use constant current power supply (this mode has high efficiency, PF value up to 0.95, high cost performance)
2. Constant voltage mode (stable performance, but low efficiency and high cost) The power supply has passed international certification safety testing to ensure that the operating value of the power drive is at a safe value
