 With the development of LED lighting industry, as LED backlight derived LED panel lights, the light uniform, no glare, fine structure, has been a lot of people love, is the new trend of modern fashion interior lighting.

 With the development of LED lighting industry, as LED backlight derived LED panel lights, the light uniform, no glare, fine structure, has been a lot of people love, is the new trend of modern fashion interior lighting.

The main part of the LED panel light

1. Panel light aluminum frame:

Is the main channel of LED cooling, the appearance of simple and generous, you can use ZY0907, the use of mold stamping die low cost, processing costs are low; die-cast aluminum frame IP level can be higher, the surface texture is good, the overall appearance, but the early put mold costs Higher.

2.LED light source:

Usually LED lamp beads use 3528, it was also used 3014 and 5050.3014 and 5050 low cost, light effect slightly worse, the key is its light guide network design difficulties. 3528 luminous efficiency of high network point of good versatility.

3.LED light guide plate:

The side of the LED light through the network refraction of the light from the front evenly derived, light guide plate is the key to LED panel light quality control. Network design is not good, see the overall light effect is very poor, the general will appear on both sides of the dark side of the dark, or there is light into the light band, or visible local dark area, or there are different angles of brightness inconsistencies. To improve the light efficiency of the light guide plate mainly by the design of the network, followed by the quality of the plate, but no need to superstition brand-name plate, qualified plate between the light transmission rate is usually almost the same. General small LED lights factory are directly used to buy a common light guide plate, you do not need to re-proofing design, more manufacturers use the public version is usually qualified.

4.LED Diffusion Board:

The light guide plate light evenly derived, but also play a fuzzy dot role. Diffuse plate generally use the acrylic 2.0 sheet or PC material, almost the PS material, the lower the cost of acrylic and light transmission than the PC slightly higher, acrylic brittle anti-aging performance is weak, PC price is slightly more expensive, but anti-aging performance Strong. Diffuse plate can not be seen after the installation of outlets, and the light transmission rate to about 90%. Acrylic transmittance at 92%, PC 88%, PS probably also 80%, we can according to the needs of the diffusion plate material selection, the majority of manufacturers are using acrylic materials.

5. Reflective paper:

The light guide plate on the back of the remaining light reflected to improve the luminous efficiency, usually RW250.

6. Rear cover:

The main role is to seal the LED panel lights, generally with 1060 aluminum, but also play a little heat dissipation.

7. Drive power:

There are two kinds of LED drive power, one is the use of constant current power supply, this mode is high efficiency, PF value of up to 0.95, cost-effective; Second, the use of constant pressure with constant current power supply, stable performance, but low efficiency, high cost, This power is mainly exported, the other side requires a certification request, the need to use a safety power supply. In fact, the use of household constant current power supply is very safe, because users are difficult to access to power, and the lamp itself is the use of safe low voltage.

8. Install the pendant:

Hanging wire, mounting bracket, etc. for the installation of fixed accessories.

From the point of view of quality control, it is most effective to increase the light effect by adding additional money to the LED light source and the LED light guide plate. From the point of view of the market sale, the additional money is spent on the aluminum frame cover pendant Can improve product quality.
