With the development of the LED lighting industry, the Back-lit Panel Light, which is derived from the LED backlight, has uniform light, no glare, and exquisite structure. It has been loved by many people and is a new trend in modern and fashionable indoor lighting.

The main components of Back-lit Panel Light:

1. The Back-lit Panel Light aluminum frame is the main channel for LED heat dissipation. The appearance is simple and generous. The cost of stamping and opening by mold is low, and the processing cost is low; the IP rating of die-cast aluminum frame can be higher, the surface texture is good, and the overall appearance is beautiful. However, the cost of investing in molds in the early stage is relatively high.
2. Back-lit Panel Light light source usually uses 3528 LED lamp beads, and some people use 3014 and 5050. A led desk lamp is a desk lamp that uses LEDs or light-emitting diodes as light sources. LEDs are solid-state semiconductor devices that can directly convert electricity into light.
3. Back-lit Panel Light light guide plate: The side LED light is refracted through the dots so that the light is uniformly exported from the front. The light guide plate is the key point of Back-lit Panel Light quality control. The led light emitting diode is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. Generally, small Back-lit Panel Light factories directly buy public light guide plates for use, and do not need to re-proof the design. The public version used by many manufacturers is usually of good quality.
4. Back-lit Panel Light diffuser:
The light of the light guide plate is uniformly led out, and it can also play the role of blurring the dots. Diffusion plates generally use acrylic 2.0 sheets or PC materials, but PS material is almost the same. Acrylic has a lower cost and a slightly higher light transmittance than PC. Acrylic is brittle and has weak anti-aging properties. PC is slightly expensive but has anti-aging properties. powerful. After the diffuser is installed, the dots cannot be seen, and the light transmittance should be around 90%. The light transmittance of acrylic is 92%, PC is 88%, and PS is about 80%. You can choose the diffuser material according to your needs. At present, most manufacturers use acrylic materials.
5. Back-lit Panel Light reflective paper reflects the remaining light on the back of the light guide plate to improve light efficiency, generally RW250.
6. The main function of the back cover is to seal the Back-lit Panel Light, usually 1060 aluminum, which can also play a role in heat dissipation.
7. Back-lit Panel Light driver power supply currently has two kinds of LEDs. One is to use constant current power supply, this mode has high efficiency, the PF value is as high as 0.95, and it is cost-effective; the other is to use constant voltage with constant current power supply, which has stable performance but efficiency. Low and high cost. Generally, this type of power supply is mainly used for export. The other party requires certification requirements and must use a safety-related power supply. 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 safe low-voltage electricity.
8. Back-lit Panel Light installation pendant, suspension wire, installation bracket and other accessories used for installation and fixation.
From the perspective of quality control, it is the most effective to spend additional money on Back-lit Panel Light and Back-lit Panel Light to improve light efficiency. From a marketing perspective, spend the additional money In terms of aluminum frame cover pendants, etc., the product level can be improved.
