1. Aluminum frame: Appearance structure, and the main structure of the heat dissipation of Round LED ceiling panel light - generally using aluminum extrusion die, the initial cost is low, the surface treatment is beautiful, and the heat dissipation effect is good. I went to the exhibition a few days ago and found that some manufacturers began to do die casting In this way, the IP level can be made a little higher, and the sealing is better, and the overall appearance is beautiful, but the cost of the initial investment in the mold is high.

2. Diffuser plate: The light of the light guide plate is evenly diffused, and it also plays the role of blocking the dots - the diffuser plate 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 brittle anti-aging 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 about 90%. The light transmittance of acrylic is 92%, and that of PC is 88%. You can choose the material of the diffuser according to your needs, and acrylic materials are generally used.

3. Light guide plate: The side LED light is refracted through the dots to change the light angle and scatter - the light guide plate is the heart of the Round LED ceiling panel light. The dot design is very important. If the dot design is not good, the overall light effect you see is very poor. Generally, 1. The middle is bright, and the two sides are dark. 2. There are bright edges on the incoming 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 network, followed by the selection of the plate, but it is not right to blindly pursue the brand plate.

4. Reflective paper: Reflect the residual light on the back of the light guide plate—usually RW250.

5. Rear cover: sealed lamp body - generally AL aluminum, the overall texture is strong, and can play a little role in heat dissipation.

6. The light source of Round LED ceiling panel light generally uses 3528, and some people also use 5630 and 5050. 5630 and 5050 have low light efficiency and difficult dot design, poor versatility, but low cost. 3528 has high luminous efficiency and strong versatility. Generally, it can be used directly by buying other light guide plates at the beginning, without the need for re-proofing and design.

The above is the content of the structure of the Round LED ceiling panel light. I think everyone has a comprehensive understanding now.
