What are the materials of LED panel light power supply?
At present, LED panel light power supplies are widely used in various fields. I believe everyone is interested in knowing what materials are made of LED panel light power supplies. After all, it is related to what we should pay attention to in use. , In order to allow everyone to use the LED panel light power supply reasonably in the future, the editor will take you to understand what materials are composed of the LED panel light power supply?
The composition of LED panel light power supply:
1. LED light guide plate, the side LED light is refracted through the dots so that the light is evenly exported from the front, the light guide plate is the key point of the quality control of the LED panel light. Generally, there will be light in the middle and dark on both sides, or there will be bright light bands at the incoming light, or local dark areas may be visible, or there may be inconsistent brightness at different angles.
To improve the light efficiency of the light guide plate mainly depends on the design of the dots, followed by the quality of the plate, but there is no need to be superstitious about the plates of the first-line famous brands. The public version used is usually of acceptable quality.
2. Aluminum frame of panel light: It is the main channel for heat dissipation of LEDs. It has a simple and elegant appearance. ZY0907 can be used. The cost of die stamping is low, and the processing cost is also low; the IP level of the die-cast aluminum frame can be higher, the surface texture is good, and the overall Beautiful, but the initial investment in the mold cost is high.
3. LED light source: Usually LED lamp beads use 3528, and some people use 3014 and 5050. 3014 and 5050 have low cost and slightly poor light efficiency. The key is that the design of their light guide points is difficult. 3528 has high luminous efficiency and good dot versatility.
Fourth, driving power supply, there are currently two kinds of LED driving power supply, one is using constant current power supply, this mode has high efficiency, the PF value is as high as 0.95, and the cost performance is high. The second is to use a constant voltage and constant current power supply, which has stable performance, but low efficiency and high cost. Generally, this power supply is mainly used for export. The other party requires certification requirements and must use a power supply with safety regulations. In fact, it is very safe to use a constant current power supply at home, because it is difficult for users to access the power supply, and the lamp body itself uses a safe low-voltage power supply.
5. LED diffuser plate: The light of the light guide plate is evenly exported, and it can also play the role of blurring the dots. The diffuser plate generally uses acrylic 2.0 sheet or PC material. The PS material is almost the same. The cost of acrylic is lower and the light transmittance is slightly higher than that of PC. Acrylic is brittle and has weak anti-aging performance. powerful.
After the diffuser is installed, the dots cannot be seen, and the light transmittance should be about 90 percent . The light transmittance of acrylic is 92 percent , PC is 88 percent , and PS is about 80 percent . You can choose the material of the diffuser according to your needs. At present, most manufacturers use acrylic materials.
Reflective paper: Reflect the residual light on the back of the light guide plate to improve the light efficiency, generally RW250.
Rear cover: The main function is to seal the LED panel light, generally using 1060 aluminum, which can also play a role in heat dissipation.
