Main Components of Led Panel Light From:www.lgiled.com Reporter:pamela Date:2013/10/8 19:42:32 Tags:led-bulb-lowes led-downlight-fittings
1 , led 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 light:
Usually led lamp beads used 3528 , it was also used 3014 and 5050.3014 and 5050 , low cost, light efficiency slightly worse, the key is its light guide network design problems. 3528 high luminous efficiency point common good .
3, LED light guide plate :
LED light through the side outlets refraction so that light from the front even exported the LED panel light guide plate [ 2 ] 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 diffuser 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 , the rear cover :
Main role is sealed LED panel lights , usually with 1060 aluminum, can also play a little cooling effect .
7, the drive power :
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, the installation hangs :
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.
