What are the main components of office 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 LED panel light seems to be just a simple lighting fixture, but due to its high market positioning, customers have extremely demanding quality requirements for this product, and the product itself involves materials, optics, structure, hardware, electronics, etc. Areas.
The main components of office LED panel lights are:
1. Panel light aluminum frame
The main channel for LED heat dissipation has a simple and elegant appearance. You can use ZY0907. The cost of stamping and opening is low and the processing cost is low. The die-cast aluminum frame can have a higher IP rating, good surface texture, and an overall beautiful appearance.
2. LED light source
Usually LED lamp beads to use 3528, and some people use 3014 and 5050. The cost of 3014 and 5050 is low, and the light effect 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 led out 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 believe in the first-line plate, and the light transmittance between qualified plates is usually the same.
4. Drive power
There are currently two types of LED drive power supplies. One is to use a constant current power supply. This model has high efficiency, with a PF value of up to 0, 95, and is cost-effective; the other is to use a constant voltage and constant current power supply with stable performance. Generally, this power supply is mainly used For export, the other party requires certification requirements, and a safety-related power supply must be used.
5. Reflective paper
Reflect the remaining light on the back of the light guide plate to improve 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.
