With the development of the LED lamp industry, the LED panel lamp derived from the LED backlight has uniform light, no glare, and exquisite structure, which has been loved by many people and is a new trend of modern fashion interior lighting.
First, the main components of the LED panel light
1. Panel light aluminum frame:
It is the main channel for LED heat dissipation. It has simple and elegant appearance. It can use ZY0907. It has low cost for mold stamping and low processing cost. The IP grade of die-cast aluminum frame can be higher, the surface texture is good, and the overall appearance is beautiful. Higher.
2. LED light source:
Usually, the LED lamp bead uses 3528, and some people use 3014 and 5050. The 3014 and 5050 have low cost and the light effect is slightly worse. The key is that the design of the light guiding dot is difficult. 3528 high efficiency and good versatility.
3. LED light guide:
The side LED light is refracted through the dots to evenly lead the light from the front side. The light guide plate is the key point for the quality control of the LED panel light. The design of the dot is not good, and the overall light effect seen is very poor. Generally, there will be darkness on both sides of the middle light, or there may be a bright band at the entrance light, or a partial dark area may be visible, or the brightness may be inconsistent at different angles. To improve the light effect of the light guide plate mainly depends on the design of the mesh point, followed by the quality of the plate, but there is no need to superstitiously the first-line brand plate, the light transmittance between the qualified plates is usually almost the same. The general small LED lamp factory is directly used to buy a common light guide plate, so there is no need to re-sample the design, and the public version used by many manufacturers is usually qualified.
4. LED diffuser:
The light of the light guide plate is evenly extracted, and the function of the fuzzy dot can also be played. The diffuser board generally uses Acrylic 2.0 sheet or PC material, which is almost PS material. Acrylic has lower cost and light transmittance higher than PC. Acrylic brittle anti-aging performance is weak, PC price is slightly expensive, but anti-aging performance Strong. The diffuser plate cannot see the dots after being mounted, and the light transmittance is about 90%. The acrylic transmittance is 92%, the PC is 88%, and the PS is about 80%. You can choose the diffuser material according to your needs. At present, most manufacturers use acrylic materials.
5. Reflective paper:
Reflecting the residual light on the back of the light guide to improve the light efficiency, generally RW250.
6. 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.
7. Drive power:
At present, there are two kinds of LED driving power sources. One is to use constant current power supply. This mode has high efficiency, PF value is up to 0.95, and cost-effective. Secondly, constant voltage with constant current power supply is used, and the performance is stable, but the efficiency is low and the cost is high. This kind of power supply is mainly for export, the other party requires certification requirements, and a safe power supply is required. In fact, it is safe to use a constant current power supply in the home because it is difficult for the user to access the power supply, and the lamp body itself uses a safe low voltage power supply.
8. Install the pendant:
Suspension wires, mounting brackets, etc. are used to mount fixed accessories.
From the perspective of quality control, it is most effective to increase the light efficiency in the LED light source and the LED light guide plate. From the perspective of market sales, the additional money is spent on the aluminum frame cover pendant. Can improve product quality.
