1. Panel light aluminum frame:
It is the main channel for led heat dissipation, the appearance is simple and generous, ZY0907 can be used, the cost of mold stamping is low, and the processing cost is low; the IP grade of die-cast aluminum frame can be higher, the surface texture is good, the overall appearance is beautiful, but the initial investment cost Higher.
2, led light source:
Usually LED lamp beads use 3528, others use 3014 and 5050. 3014 and 5050 cost is low, the light effect is slightly worse, the key is the difficulty in designing its light guide dots. 3528 light effect high point versatility.
3, LED light guide:
The side LED light is refracted through the dots to evenly lead the light from the front side. The light guide plate is the key point for the quality control of the LED panel light. The design of the dot is not good, and the overall light effect seen is very poor. Generally, there will be darkness on both sides of the middle, or there may be a bright band at the entrance light, or a partial dark area may be visible, or the brightness may be inconsistent at different angles. To improve the light effect of the light guide plate mainly depends on the design of the mesh point, followed by the quality of the plate, but there is no need to superstitiously the first-line brand plate, the light transmittance between the qualified plates is usually almost the same. The general small LED lamp factory is directly used to buy a common light guide plate, so there is no need to re-sample the design, and the public version used by many manufacturers is usually qualified.
4, LED diffuser:
The light of the light guide plate is evenly distributed, and can also function as a fuzzy dot. The diffuser board generally uses Acrylic 2.0 sheet or PC material, almost the PS material, the cost of acrylic is lower and the light transmittance is slightly higher than PC, the acrylic anti-aging performance is weak, the price of PC is slightly expensive, but the anti-aging property Strong. The diffuser plate cannot see the dots after being mounted, and the light transmittance is about 90%. The acrylic transmittance is 92%, the PC is 88%, and the PS is about 80%. You can choose the diffuser material according to your needs. Most manufacturers use acrylic materials.
5. Reflective paper:
Reflecting the residual light on the back of the light guide to improve the light efficiency, generally RW250.
6, the rear cover:
The main function is to seal the LED panel light, generally using 1060 aluminum, which can also play a role in heat dissipation.
7, the drive power:
There are 2 kinds of led drive power supply, one is to use constant current power supply, this mode has high efficiency, PF value is up to 0.95, cost-effective; the second is to use constant voltage with constant current power supply, stable performance, but low efficiency, high cost, generally use this The power source is mainly for export, and the other party requires certification requirements, and a power source with safety regulations must be used. In fact, it is safe to use a constant current power supply in the home because it is difficult for the user to access the power supply, and the lamp body itself uses a safe low voltage power supply.
8, install the pendant:
Suspension wires, mounting brackets, etc. are used to mount fixed accessories.
From the perspective of quality control, it is most effective to increase the light efficiency in the LED light source and the LED light guide plate. From the perspective of market sales, the additional money is spent on the aluminum frame cover pendant. Can improve product quality.
