Detailed explanation of 8 major components of LED panel lights
With the development of the LED lighting industry, LED panel lights, which are derived from LED backlights, have uniform light, no glare, and delicate structure, which have been loved by many people and are a new trend in modern and fashionable indoor lighting.
1. Panel light aluminum frame:
It is the main channel for LED heat dissipation, with a simple and elegant appearance. ZY0907 can be used. The cost of mold opening and processing 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, but the cost of the mold 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 its light guide points 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 can be exported evenly 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 will be very poor. Generally, there will be a bright middle and dark sides on both sides, or there will be a bright light band at the incoming light, or a local dark area may be visible, or there will 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 superstitious the first-line famous brand plate, the light transmittance between qualified plates is usually almost the same.
4. LED diffuser:
The light of the light guide plate is evenly exported, and it can also play the role of blurring the dots. The diffuser plate generally uses acrylic 2.0 sheet or PC material. The PS material is almost the same. The cost of acrylic is lower and the light transmittance is slightly higher than that of PC. Acrylic is brittle and has weak anti-aging performance. powerful. After the diffuser is installed, the dots cannot be seen, and the light transmittance should be about 90 percent .
5. Reflective paper:
Reflect 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 is used, which can also play a little role in heat dissipation.
7. Drive power:
At present, there are two kinds of LED driving power supply, one is to use constant current power supply, this mode has high efficiency, PF value is as high as 0.95, and the cost performance is high; the other is to use constant voltage and constant current power supply, with stable performance, but low efficiency and high cost, generally used This kind of power supply is mainly exported, and the other party requires certification requirements and must use a power supply with safety regulations.
8. Install the pendant:
Suspension wires, mounting brackets, etc. are used to install and fix accessories.
From the perspective of quality control, it is most effective to spend additional money on LED light sources and LED light guide plates in order to improve light efficiency. From the perspective of market sales, spend additional money on aluminum frame cover pendants and other aspects Can improve product quality.
