With the development of the LED lighting industry, the LED panel light derived from the LED backlight has uniform light, no glare, and exquisite structure. It is loved by many people and is a new trend in modern and stylish indoor lighting.
Main components of LED panel light
 1. Aluminum frame for panel light:
It is the main channel for LED heat dissipation. The appearance is simple and generous. ZY0907 can be used. The mold opening cost is low and the processing cost is low. The IP level 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 use 3528 for LED lamp beads, and some people use 3014 and 5050. 3014 and 5050 have low cost and slightly lower light efficiency. The key is the difficulty in designing the light guide network. 3528 has high luminous efficiency and good versatility.
3. LED light guide plate:
  Reflect the side LED light through the dots to make the light evenly lead from the front. The light guide plate is the key point of the quality control of the LED panel light. If the dot design is not good, the overall light effect will be very poor. Generally, there will be dark sides in the middle, or there will be bright bands in the light entrance, or local dark areas may be visible, or inconsistencies in brightness at different angles. To improve the light efficiency of the light guide plate mainly depends on the design of the outlet, followed by the quality of the plate, but there is no need to superstition the first-line brand plate, and the light transmittance between qualified plates is usually almost the same. Generally, small LED lamp factories directly buy common light guide plates for use, so there is no need to re-proof the design. The public version used by many manufacturers is usually of good quality.
4. LED diffuser:
   Evenly extract the light from the light guide plate, and also play a role of blurring the dots. The diffuser board generally uses acrylic 2.0 sheet or PC material. The PS material is almost the cost. Acrylic has a lower cost and a higher light transmittance than PC. Acrylic is brittle and has weak anti-aging properties. The price of PC is slightly expensive, but anti-aging properties Strong. After installing the diffusion plate, the dots cannot be seen, and the light transmittance should be about 90%. Acrylic light transmittance is 92%, PC is 88%, and PS is about 80%. You can choose the material of the diffuser plate according to your needs. At present, most manufacturers use acrylic materials.
 5. Reflective paper:
  Reflects the residual light on the back of the light guide plate to improve the light efficiency, generally RW250.
6. Rear cover:
   The main function is to seal the LED panel light, generally 1060 aluminum, which can also play a role in heat dissipation.
 7. Drive power:
There are currently two kinds of LED drive power supplies. One is to use a constant current power supply. This mode has high efficiency, with a PF value of up to 0.95, which is cost-effective. The second is to use a constant voltage power supply with constant current and stable performance. This type of power supply is mainly for export. The other party requires certification requirements and must use safety-compliant power supplies. In fact, it is very safe for families to use constant current power supply, because users are difficult to access the power supply, and the lamp body itself uses safe low-voltage electricity.
8. Install the pendant:
  Suspended wires, mounting brackets, etc. are used to install fixed accessories.
From the perspective of quality control, it is most effective to spend the additional money on the LED light source and the LED light guide plate to improve the light efficiency. From the perspective of marketing, spend the additional money on the aluminum frame cover pendant, etc. Can improve product quality.
