LED panel lights have the following parts, so, in order to choose the right LED panel light, choosing the suitable component is the most correct way.

　　1 panel light aluminum frame:

　　Is led cooling the main channel, simple and elegant appearance, you can use ZY0907, using die stamping tooling costs, low processing costs are low; die-cast aluminum frame IP rating can be a little higher, surface texture, and overall appearance, but the initial investment cost of mold higher.

　　2.led source:

　　Usually led lamp beads used 3528, it was also used 3014 and 5050 which would be lower cost, light efficiency slightly worse, the key is its light guide network design problems.

　　3.LED light guide:

　　LED light through the side outlets refraction so that light from the front even exported the LED panel light guide plate Quality control key points. Network design is not good, to see the overall optical efficiency on the poor, the middle light will appear on both sides generally dark, or there is a light at the light into the band, or focally dark area, then there are different angles or brightness inconsistent. To improve the efficiency of light guide plate depends mainly on network design, followed by the quality of the plate, but do not need superstition famous line of the plate, the light transmittance pass between the plates is usually almost the same. General Factory is a small LED light guide plate directly buying public use, you do not need to re-proofing design, many manufacturers use the public version of the usual quality standards.

　　4.LED diffusion plate:

　　The uniformity of the light guide plate export, but also play the role of fuzzy dot. General use acrylic diffuser plate or sheet 2.0 PC material, almost is PS material, acrylic low cost and high transmittance higher than the PC, acrylic brittle weak anti-aging properties, PC prices slightly expensive, but anti-aging properties Strong. Installed after the diffuser plate can not be seen in the network, and the transmission rate to about 90%. Acrylic light transmittance at 92%, PC was 88%, PS probably also 80%, we can according to demand diffuser plate material selection, most manufacturers are using acrylic materials.

　　5 reflective paper:

　　Reflected off the back corner of the light guide plate in order to improve light efficiency, generally RW250.

　　6 Rear cover:

　　Main role is sealed LED panel lights, usually with 1060 aluminum, can also play a little cooling effect.

　　7 Power Supply:

　　There are two kinds of led power supply, one using constant current power supply, this mode efficiency, PF value up to 0.95, cost-effective; two is to use the constant voltage with constant current power supply, stable performance, but low efficiency, high cost, general use This power is mainly exported, the other required certification requirements, safety regulations require the use of a power supply. In fact, a constant current power supply for home use is safe, because the user is difficult to reach the power supply and lamp body itself using a safe low voltage.

　　8 Installation accessories:

　　Suspension wire, mounting brackets and other accessories for mounting.

　　From the perspective of quality control, to improve the optical efficiency of the additional money on the LED light source and LED light guide plate is the most effective, from the marketing point of view, the additional money to cover the aluminum frame pendant, etc. can improve product quality.
