What Are The Main Components of LED Panel Light?

1. Aluminum frame of LED panel light


It is the main channel for the LED to dissipate heat and it has a simple and generous appearance. It uses open die stamping at a low price and the processing cost is also low. The IP level of the die-cast aluminum frame can be higher. It has a good surface texture and a beautiful appearance. However, the early investment in the mold is relatively high.


2. The light source of LED panel light


In general, 3528 is used for LED light beads, and 301(permanent redirection) and 5050 are also used by some people. A LED desk lamp uses LED or light-emitting diodes as the light source. LED is a solid-state semiconductor device that can directly convert electricity into light, and the LED lighting technology it uses is the third-generation lighting technology.


3. Light guide plate of LED panel light


The side LED light is refracted through the dots so that the light can be uniformly exported from the front. The light guide plate is the key for the quality control of the LED panel light.


The LED light-emitting diode is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. The heart of the LED is a semiconductor chip, with the negative end attached to a holder and one end connected to the positive pole of the power supply to enclose the entire chip in epoxy resin.


In general, a small led panel light suppliers directly purchase public light guide plates to use, and it does not need to re-proof the design. The public plates used by many manufacturers usually have qualified quality.


4. Diffusion board of LED panel light


The light of the light guide plate can be evenly exported, and it can also play the role of blurring the dots. In general, the diffusion board uses acrylic 2.0 sheets or PC materials, or PS materials. The cost of acrylic is lower and the light transmittance is slightly higher than that of PC materials, but it has weak anti-aging performance. The price of PC materials is slightly expensive but with great anti-aging performance. The dots cannot be seen after the diffusion board is installed, 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 diffusion board material based on your needs. Currently, most manufacturers use acrylic materials.


5. Reflective paper of LED panel light


The light efficiency can be improved by reflecting the remaining light on the back of the light guide plate with generally RW 250.


6. Rear cover of LED panel light


The main function is to seal the LED panel light. In general, it uses 1060 aluminum, which can also play the role of radiating.


7. Drive power supply of LED panel light (a device that can provide power to electronic equipment)


Currently, there are two types of LED drive power supplies. The first type uses a constant current power supply, which has high efficiency with a PF value of up to 0.95. And it is cost-effective. The second type uses constant voltage with a constant current power supply, which has stable performance but low efficiency and high cost. In general, the second type of power supply is mainly used for export and it should have certification requirements that can be provided to the other party to ensure a safe 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 light body uses safe low-voltage electricity.
