Resolve the structural problems of Rectangle LED Panel Lights
At present, Rectangle LED Panel Lights is becoming more and more popular in indoor lighting, whether it is hotel, conference room, factory or office, commercial use, residential or public facilities, schools, hospitals as long as there is energy saving or high color Most of the place has been using Rectangle LED Panel Lights to replace the traditional fluorescent lamp, on the one hand Rectangle LED Panel Lights has played a role in energy saving and environmental protection, on the other hand to create a good lighting atmosphere. What is the internal structure of it?
Generally from the big side, we put a Rectangle LED Panel Lights is divided into seven components, the following we have a detailed understanding of the seven parts of it!
1, aluminum frame
Rectangular LED Panel Lights Aluminum frame appearance of the composition and the main structure of the LED cooling The general use of the general use of AL6063, aluminum extrusion, pre-cost low input, beautiful surface treatment, good heat dissipation, but if the use of die-casting frame, this will not only improve the IP protection level, And sealed light better, the overall appearance, but the higher cost of pre-injection molds.
2, light guide plate
Rectangle LED Panel Lights light guide plate is the heart of the flat light, the network design is very important, the network design is not good, see the overall light effect is very poor, generally will appear 1. The middle of the bright, both sides of the dark; 2. into the light side of the bright side, the middle dark; 3. standing in different angles, the overall brightness is inconsistent; 4. local dark area obvious. Light guide plate of the light effect of a large part of the design in the network, followed by the selection of the plate, but blindly pursue the brand plate is wrong, because many brands like Japan's Mitsubishi, most of its good plate are People ordered a good, many of the market out of the Mitsubishi plate for some 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 Yes.
3. Diffusion plate
Rectangle LED Panel Lights The role of the diffuser plate is to spread the light of the light guide plate evenly, as well as the role of shielding the network, the diffusion plate generally use the acrylic 2.0 sheet or PC material, the lower the cost of acrylic and light transmission than the PC High slightly higher, acrylic brittle anti-aging performance is weak, 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%. Acrylic transmittance at 92%, PC 88%. We can according to the needs of the choice of diffusion plate material, the general use of acrylic materials.
4. reflective paper
Reflective paper is mainly the light guide plate on the back of the light reflected in the general RW250.
5.LED light source
The general use of SMD3528 also use 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. SMD3528 high efficiency of high point network.
6. Rear cover
Sealed lamp body - generally AL aluminum, the overall texture is strong, and can play a little heat dissipation.
7. Drive the power supply
The current Rectangle LED Panel Lights has two power modes 1. Direct use of constant current power supply (this mode is high efficiency, PF value of up to 0.95, cost-effective) 2. Constant pressure with constant current 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, direct use of safety power can be shipped to various countries, the use of a wide range.
