With the development of LED lighting industry, LED backlight as a derivative of the LED plate lights, the light uniform, no glare, the structure of the fine characteristics of the people loved.
So, led flat lamp design and precautions and what? Hope that through the reading of this article, we have to help Kazakhstan.
First of all, LED Flat Panel Lights we first understand the main structure of the light source structure:
Led plate light appearance structure, and LED cooling the main structure - the general use of AL6063, aluminum extrusion die, pre-cost low input, beautiful surface treatment, cooling effect is good, a few days ago to see the exhibition also found that manufacturers began to die-casting the framework, This IP level can do a little higher, and the closure of light better, the overall appearance, but the pre-injection mold costs higher.
The light guide plate light evenly spread out, as well as play a role in blocking the network - the proliferation of the general use of acrylic 2.0 sheet or PC material, the lower the cost of acrylic and light transmission than the PC slightly higher, acrylic crisp anti-aging Performance is weak, LED Flat Panel Lights PC prices are slightly more expensive, but anti-aging performance.
Diffuse plate can not be seen after the installation of outlets, and the light transmission rate to about 90%. The acrylic transmittance was 92% and the PC was 88%. We can according to the needs of the diffusion plate material selection, the general use of acrylic materials.
Led plate light guide plate
The side of the LED light through the dot refraction to change the angle of light scattered - light guide plate is the heart of flat lights, network design is very important, the network design is not good, LED Flat Panel Lights see the overall light effect is very poor, generally appear:
1. The middle is bright and dark on both sides
2. into the light side with bright side, the middle dark
3. standing in different angles, LED Flat Panel Lights the overall brightness is inconsistent
4. Local dark area obvious.
Light board a lot of light efficiency in the design of the network, followed by the selection of the plate, but blind pursuit of the brand plate is wrong, because many brands, LED Flat Panel Lights most of the good plate are ordered to be good , Many of the market out of the plate for the scrap, the light transmission rate is not as high as their own plate, so the choice of plate does not necessarily look at the plate manufacturers, as long as the test light transmittance high efficiency OK, in fact, it can.
Led flat light reflective paper
The light guide plate on the back of the remaining light reflected - usually RW250.
Led plate light rear cover
Sealed lamp body - generally AL aluminum, the overall texture is strong, LED Flat Panel Lights and can play a little heat dissipation.
LED light source
The general use of 3528 also used 5630 and 5050,5630 and 5050 light efficiency is not high and the network design is difficult, versatility is poor, but the cost is low. 3528 luminous efficiency of high dot versatility, generally just do can be directly to buy other home light guide plate use, do not need to re-proofing design.
Drive power supply
Led flat lamp lamp drive - there are two kinds of power supply:
1, the direct use of cross-flow power (this mode is high efficiency, PF value of up to 0.95, cost-effective);
2, constant pressure with cross flow mode (stable performance, but low efficiency, high cost).
The general use of this model is to require certification of the customer design, because the lamp is 24V input low-voltage lamps, do not need to do security, LED Flat Panel Lights direct use of safety power can be shipped to various countries.
