With the development of the LED lamp industry, LED panel lights derived from LED backlights have uniform light, no glare, and exquisite structure. They are loved by many people and are a new trend in modern and stylish interior lighting.
1. Panel light aluminum frame
It is the main channel for LED heat dissipation. The appearance is simple and generous. ZY0907 can be used. The cost of die pressing and opening is low, and the processing cost is low. The IP grade of the die-cast aluminum frame can be higher, the surface texture is good, and the overall appearance is beautiful. Higher.
2.LED light source
Usually LED lamp beads use 3528, and some people use 3014 and 5050. 3014 and 5050 have low cost and slightly worse light efficiency. The key is the difficulty in designing the light guide network. 3528 has high light efficiency and good versatility.
3.LED light guide plate
The side LED light is refracted through the dots so that the light is uniformly led from the front. The light guide plate is the key point of the quality control of the LED panel light. The dot design is not good, and the overall light effect is very poor. Generally, the two sides of the center are dark, or there is a bright light band at the light entrance, or the local dark area is visible, or the brightness is different 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 superstitize first-line brand plates, and the transmittance between qualified plates is usually not much different.
The light from the light guide plate is evenly exported, and it can also play a role of blurring the dots. The diffuser plate generally uses acrylic 2.0 sheet or PC material. The PS material is almost. The cost of acrylic is lower and the light transmittance is slightly higher than that of PC. The acrylic brittleness and anti-aging performance are weak. The price of PC is slightly more expensive, but the anti-aging performance. Strong. After the diffuser plate is installed, the dots cannot be seen, and the light transmittance should be about 90%.
Reflect the residual light on the back of the light guide plate to improve the light efficiency, generally RW250.
The main role is to seal the LED panel light, generally using 1060 aluminum, can also play a little role in heat dissipation.
There are currently two types of LED driving power. One is to use a constant current power supply. This mode has high efficiency, a PF value of 0.95, and a high cost performance ratio. The second is the use of a constant voltage and constant current power supply, which has stable performance, but low efficiency and high cost. It is generally used. This type of power supply is mainly for export. The other party requires certification requirements and must use a power supply with safety regulations.
