LED Panel Lights Of The Eight Major Parts Detailed
LED panel lights of the eight major parts detailed
With the development of LED lighting industry, as LED backlight derived from the LED panel lights, the light uniform, no glare, exquisite structure, LED panel light has been a lot of people love, is the modern fashion interior lighting new trend.
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 investment in mold costs Higher.
2.LED light source:
Often 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 difficult. 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, LED panel light the general will appear on both sides of the dark side of the dark, or there is a light band into the light, or visible local dark areas, or appear different 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.
4.LED Diffusion Board:
The light guide plate light evenly derived, but also play a role in fuzzy network. 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, LED panel light 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%.
5. Reflective paper:
The light guide plate on the back of the remaining light reflected to improve the light 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, LED panel light but low efficiency, high cost, This power is mainly exported, the other request for certification requirements, the need to use safety power supply.
8. Install the pendant:
Hanging wire, mounting bracket, etc. for the installation of fixed parts.
From the point of view of quality control, it is most effective to increase the luminous efficiency to spend extra money on the LED light source and the LED light guide plate. From the point of view of the market sale, LED panel light the additional money is spent on the aluminum frame cover pendant Can improve product quality.
