With the development of LED lighting industry, as the LED backlight ramifications LED panel light, its light uniformity, no glare, delicate structure to give a lot of people's favorite, is the new trend of modern fashion indoor lighting.

The main part of the LED panel light


1. The panel light aluminum frame:

Is the main channel LED cooling, Simple and elegant appearance, you can use ZY0907, using die stamping low mold costs, 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:

Typically LED lamp beads using 3528, 3014 was also the use of low cost and 5050.3014 and 5050, slightly worse luminous efficiency, the key is its light guide network design problems. 3528 light-efficient outlets common good.


3.LED light guide:

The sides of the LED light refracted through the network so that uniform light derived from the front, the light guide plate is the key point LED panel light quality control. Network design is not good, to see the overall effect on the poor light, usually appear in the middle on both sides of dark light, or light into the Department has occurred with light or dark areas visible locally, and then there are different angles or brightness inconsistent. To improve the efficiency of light guide plate depends mainly on the design of the network, followed by the quality of the plate, but it is not necessary to superstition famous line of the plate, the light transmittance between the plates is usually qualified almost the same. General small LED lights are a direct factory to buy the common use of the light guide plate, you do not need to re-proofing design, many manufacturers use the public version of the usual quality standards.


4.LED diffusion plate:

The homogeneous light guide plate export, but also play the role of fuzzy outlets. 2.0 diffusion plate is generally used acrylic sheet material or PC, PS handicap is lower cost materials, acrylic and high light transmittance higher than PC, acrylic weak brittle anti-aging properties, PC prices slightly expensive, but the anti-aging properties strong. Diffusion plate mounted on the network can not see the future, and the transmission rate to about 90%. Acrylic light transmittance of 92%, PC is 88%, PS probably also 80%, we can choose the diffusion plate material according to the needs, for most manufacturers are using acrylic material.


5. Reflective paper:

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


6. Rear cover:

The main function is to seal LED panel light, usually with 1060 aluminum, can also play a little cooling effect.


7. The drive power:

There are two kinds of LED driver power supply, one constant current power supply, high efficiency of this mode, PF value up to 0.95, cost-effective; the second is to use a constant voltage with constant current power supply, stable performance, but low efficiency, high cost, generally use this is the main power outlet, the other requires a certification request shall use of safety power supply. In fact, home use constant current power supply is very safe, because users are difficult to reach power, and the use of light itself is safe low voltage.


8. Install the pendant:
Hanging wire, mounting brackets for mounting and other accessories.
From the point of view of quality control, to improve the light efficiency of the additional money in the LED light source and LED light guide plate is the most effective, from a marketing point of view, the additional money in the aluminum frame cover pendant, etc. you can enhance product quality.
