What are the main components of LED panel lights?
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 has been loved by many people and is a new trend in modern and fashionable indoor lighting.
The main components of LED panel lights
1. Panel light aluminum frame:
It is the main channel for LED heat dissipation. The appearance is simple and generous. You can use ZY0907. 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, but the mold cost is invested in the early stage. Higher.
2. LED light source:
Usually LED lamp beads use 3528, and some people use 3014 and 5050. The cost of 3014 and 5050 is low, and the light efficiency is slightly worse. The key is that the design of light guide dots is difficult. 3528 has high luminous efficiency and good dot versatility.
3. LED 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 the quality control of the LED panel light. If the dot design is not good, the overall light effect seen is very poor. Generally, the light in the middle is dark on both sides, or there is a light band at the light entrance, or there is a partial dark area, or there may be inconsistent brightness 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 be superstitious in the first-line brand-name plates, and the light transmittance between qualified plates is usually the same. Generally, small LED lamp factories directly buy public light guide plates for use, so there is no need to re-proof the design, and the public version used by many manufacturers is usually of good quality.
4. LED diffuser:
Lead the light of the light guide plate uniformly, and also play a role in blurring the dots. Diffusion plates generally use acrylic 2.0 sheets or PC materials, almost PS materials, acrylic has a lower cost and a slightly higher light transmittance than PC, acrylic is brittle and has weak anti-aging properties, and PC is slightly expensive, but it has anti-aging properties. Strong. 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. Reflective paper:
Reflect the remaining 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 is used, 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 other is to use a constant voltage with constant current power supply, which has stable performance, but low efficiency and high cost, and is generally used This kind of power supply is mainly exported, and the other party requires certification requirements, and a safety-related power supply must be used. 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. Install the pendant:
Suspension wire, mounting bracket and other accessories used to install and fix.
From the perspective of quality control, it is most effective to spend additional money on LED light sources and LED light guide plates to improve light efficiency. From the perspective of market sales, spend additional money on aluminum frame cover pendants, etc. Can upgrade the product grade.
