In recent years, LED panel lights have gradually moved towards schools and various indoor lighting places. Today, Xinjie lighting, the LED panel light manufacturer, will take you to uncover the veil of LED panel lights and gain an in-depth understanding of LED panel lights.

Classification of LED panel lights

There are two types of LED panel lights: direct-lit and side-lit.

The side-emitting LED panel light has the advantages of light weight and thin body, easy installation and transportation, etc. The disadvantage is that it is easy to emit unevenly; the advantages of the direct-lit LED panel light are sufficient brightness and cost control. The disadvantage is that glare is inevitable and there are dark areas. The lamp body is heavy, and the transportation and installation are relatively inconvenient.

The price of the side-emitting LED panel light is more expensive than that of the direct type, because the technology of the side-emitting LED panel light is relatively complicated, which is determined by the product structure of the side-emitting LED panel. Both are complicated, which makes it difficult to control product yield and product uniformity.

The structure of LED panel light

The structure of LED panel light mainly includes driving power supply, aluminum substrate, frame, diffuser plate, light guide plate, lamp beads and other components.

1) Power supply: constant current power supply mode with high efficiency

LED lights have two driving power modes, one is constant current power supply, which has high efficiency, PF value as high as 0.95, and high cost performance; the other is constant voltage and constant current power supply, with stable performance, but low efficiency and high cost.

2) Diffuser plate: different materials have different light transmittance

The function of the diffuser plate is to evenly disperse the light of the light guide plate, and it can also play the role of blurring the dots. The materials used for the diffuser plate of the LED panel light mainly include acrylic, PC, PS, etc. The light transmittance of acrylic is 92%, that of PC is 88%, and that of PS is about 80%. The light transmittance of acrylic material is higher than that of PC, and the cost is lower, and its anti-aging performance is weak; while PC material is expensive, but anti-aging Strong performance.

3) Light guide plate: The plate has a great influence on the light efficiency

The function of the light guide plate of the LED panel light is to refract the light parallel to the direction of the light-transmitting plate into the direction perpendicular to the light-transmitting plate, and the light that is refracted by the light-guiding plate to the back of the LED panel light is reflected by the reflective paper. In this process, it is necessary to reduce the light decay as much as possible. Generally speaking, the light efficiency of the LED panel light guide plate depends to a large extent on the dot design, followed by the choice of the LED panel light guide plate plate.

4) Frame: Frame strength affects durability

The frame is an important part of the LED panel light, and the high-strength frame makes the panel light more durable. The side frame of the LED panel light is made of different materials, and its heat dissipation performance is also different. According to statistics, the current frame materials of LED panel lights mainly include aluminum alloy, steel, PC, A6063, aluminum-plastic, steel and other materials.

Advantages of LED panel lights

The main advantages of LED panel light include soft light emission and no glare: LED panel light has a very soft light-emitting method. The side light-emitting method commonly used at present, the light emitted from the surface of the lamp body is very uniform, so the light emitted is not at all. dazzling. Used in various fields, it can effectively eliminate glare. LED panel lights have gradually become the best product to replace traditional grille light panels in the LED era due to their good uniformity of illumination, higher CRI, uniform and soft light, and comfort. They will be used in schools, hospitals, hotels, offices and other indoor lighting fields There will be more and more room for development.

The above is the whole content of LED panel lights brought to you by Xinjie lighting today. I hope this article can help you understand the composition, advantages and classification of LED panel lights.
