What is the main components of Edge lit LED panel lights
The main components of Edge lit LED panel lights are:
1. Aluminum frame of panel lamp
It is the main channel for LED heat dissipation. It is simple and generous in appearance. Aluminum 6063 can be used. The cost of stamping and die opening is low and the processing cost is low; The IP grade of the die cast aluminum frame can be higher, with good surface texture and overall beauty, but the cost of the early investment mold is higher.
2. LED light source
Generally, 3528 led beads are used, and 3014 and 5050 are also used. 3014 and 5050 have low cost and slightly poor light efficiency. The key is that it is difficult to design the light guide dot. 3528 has high light efficiency and good versatility.
3. Led diffuser
The light of the light guide plate can be uniformly led out, and can also play the role of blurring the dot. Generally, acrylic 2.0 plate or PC material is used for diffusion plate, and PS material is the worst. The cost of acrylic is lower and the light transmittance is slightly higher than that of PC. the brittle and anti-aging performance of acrylic is weak. The price of PC is slightly expensive, but the anti-aging performance is strong. After the diffuser plate is installed, the dot cannot be seen, and the transmittance should be about 90%. The transmittance of acrylic is 92%, that of PC is 88%, and that of PS is about 80%. You can choose the diffusion plate material according to your needs. At present, most manufacturers use acrylic materials.
4. LED light guide plate
The side LED light is refracted through the dot to make the light uniformly led from the front. The light guide plate is the key point of the quality control of the LED panel lamp. If the dot design is not good, the overall light effect will be very poor. Generally, there will be bright in the middle and dark on both sides, or there will be bright light bands at the light entrance, or visible local dark areas, or inconsistent brightness at different angles. To improve the light efficiency of the light guide plate, we mainly rely on the design of the dot, followed by the quality of the plate. However, there is no need to superstition about the plate of the first-line famous brand. The transmittance of the qualified plates is usually almost the same. Generally, small LED light factories directly buy public light guide plates for use, so there is no need to re proofing design. The public version used by many manufacturers is generally qualified.
5. Reflective paper
The residual light on the back of the light guide plate is reflected to improve the light efficiency, generally rw250.
6. Rear cover plate
The main function is to seal the LED panel lamp, generally using 1060 Aluminum, which can also play a role in heat dissipation.
7. Installation of pendant
Hanging steel wire, mounting bracket and other accessories for installation and fixation.
8. Driving power supply
At present, there are two kinds of LED driving power supplies. One is the use of constant current power supply. This mode has high efficiency, PF value as high as 0.95, and high cost performance; Second, the constant voltage and constant current power supply is used, which has stable performance, but low efficiency and high cost. Generally, this power supply is mainly used for export. The other party requires certification, and must use a power supply with safety regulations. In fact, it is very safe to use constant current power supply at home, because it is difficult for users to access the power supply, and the lamp body itself uses safe low-voltage power.
