What is the structure of led panel light?
With the continuous aggravation of the world's energy problems, green environmental protection is a key aspect of future industrial development planning. Government departments around the world are also making every effort to help and stimulate the development trend of various green and environmental protection industry chains. As a new emerald green light source commodity, LED has a pioneering development trend in the current environment. In the current lighting fixture sales market, the LED panel light occupies an increasingly large market share, especially in recent years, it has gradually become a lighting device that many customers and manufacturers love. LED panel light is a kind of lighting fixture, which has the characteristics of environmental protection and energy saving, brighter, no mercury, no infrared induction, no ultraviolet light, no interference signal, no pyroelectric effect, no radiation, and no flickering conditions. Lighting fixtures are light in weight, and there are various methods such as insertion and cable pulling, which are easy to install. Applicable to hotel restaurants, conference halls, processing plants or company offices, commercial activities, housing or public facilities, colleges, hospitals and other areas where environmental protection and energy saving and high color rendering index index value lighting are required. Below, we will introduce the structure, classification, characteristics, installation methods, common problems of installation, disassembly and assembly methods, quality identification methods, and maintenance precautions for everyone in detail. Let's master it together!
The structure of led panel light
Compared with other lighting fixtures, the structure of LED panel light is unique, and its key is composed of light source, backlight source, diffuser plate, reflective surface paper, driving power supply, etc. The structure of similar LED backlight products such as paper.
1. LED light source
Most LED panel light manufacturers use SMD patch series products, such as 3528 and 3014, in the application of LED light sources. The sales market that LED panel light manufacturers deal with is dynamic, and the manufacturer will select the light source that considers the design plan according to the specific needs of the customer for the product. The selection of LED light sources is extremely important to improve product characteristics, and is one of the key elements to improve the quality of LED panel lights.
2. Backlight
The function of the backlight is to convert the light emitted by the LED line light source into a light source according to optical technology, and to map the side LED light according to the business network to make the light source evenly derived from the reverse side. At this stage, the key to use packaging and printing backlight mode, the quality of the backlight will immediately endanger the chromaticity and uniformity of the product, it is required to have excellent light transmittance performance. The backlight source is the key link in the quality management of LED panel lights. The design scheme of the business outlets is not very good, the overall special effects obtained are poor, the light is uneven, and there will continue to be bright in the middle and dark on both sides, and there are bright bands on the incoming light. , It can be seen that some shadows, different viewing angles are inconsistent, etc. To improve the special effects of the backlight, the key to the design scheme of the business outlets is the quality of the board, and it is advisable to choose the board with high light transmittance.
3. Diffuser plate
The key function of the diffuser is to export the light of the backlight evenly, so that the distribution of the light is more even. When the light source hits the out-diffusion point, the refracted light diffuses out of each viewing angle, and then it is emitted from the back of the backlight source. Various out-diffusion points of different sizes and closeness are used to make the backlight source evenly and brightly. Improve the chromaticity of the backlight. It can also have the effect of blurring business outlets. The diffuser board is generally made of acrylic board or PC material, and it is almost PS raw material. The cost of acrylic sheet is lower, the light transmittance is slightly higher than that of PC, and the aging resistance is weak; the price of PC is slightly expensive, but the aging resistance is strong. After the diffuser is installed, the business outlets cannot be seen, and the transmittance should be around 90%. The transmittance of acrylic sheet is 92%, PC is about 90%, and PS is about 88%. Manufacturers can select the raw materials of diffuser sheets according to requirements. At this stage, most manufacturers choose acrylic sheet raw materials.
4. Reflective paper
The effect of the retro-reflective paper is to reflect the light overflowing from the backlight, so as to promote the flexible use of the light from the LED, try to use the transmittance close to 100% retro-reflective paper to maximize the profit of the light application and improve the LED panel light. Output chromaticity, generally RW250.
5. Outer cover
The key function is the sealed LED panel light, which is generally made of aluminum alloy plate, and can also have heat pipe cooling effect.
6. Drive power
At this stage, there are two kinds of LED driving switching power supply, one is the application of constant current power supply, this method has high efficiency, PF value is achieved, and high cost performance; the other is the application of constant current source with constant current power supply, stable characteristics, but high efficiency and low cost increase , The key to the general application of this type of switching power supply is the entrance and exit, and the other side has verification regulations. In fact, it is safe to use constant current power supply at home, because customers cannot touch the switching power supply, and the lamp body itself is applied with low safety voltage.
