In recent years, LED panel lights have slowly moved towards schools and various indoor lighting places. Today, the LED Panel Light Supplier will take you to uncover the veil of the LED panel light and learn more about the LED panel light.
Someone once predicted that the lights of the future will have no specific shape, and that the lights of the future will become part of the building, which you cannot easily identify at a glance. As for the panel light, some people say that it is a major performance of the lighting in this field at this stage.
LED panel lights are widely used in offices, schools, hospitals, shopping malls, homes and other places due to their good uniformity of illumination, higher display index, uniform and soft light, and comfort. They have become the best alternative to traditional grille lamp panels in the LED era. Good product.
LED Panel Light
The structure of the LED Panel Light mainly includes the frame, diffuser plate, light guide plate, lamp beads, drive power, aluminum substrate and other components.
The frame is an important part of the panel light, and the high-strength frame makes the panel light more durable. The side frames of LED panel lights use different materials, and their heat dissipation performance is also different. According to statistics, the current frame materials of panel lights mainly include aluminum alloy, steel, PC, A6063, aluminum plastic, steel and other materials.
The function of the diffuser plate is to evenly diffuse the light of the light guide plate, and can also play the role of blurring the dots. The materials used mainly include acrylic, PC, PS, etc. It is understood that acrylic has a light transmittance of 92%, PC is 88%, and PS is about 80%. Acrylic material has a higher light transmittance than PC, and has a lower cost, and its anti-aging performance is weak; while PC material is expensive, But the anti-aging performance is strong.
The function of the light guide plate is to refract the light parallel to the direction of the light transmission plate into the direction perpendicular to the light transmission plate, and the light which is refracted by the light guide plate to the back of the panel lamp by the reflective paper is reflected. In this process, it is necessary to reduce the light attenuation as much as possible. Generally speaking, the light effect of the light guide plate depends largely on the dot design, followed by the choice of the plate.
LED Lights have two drive power modes, one is a constant current power supply, this mode has high efficiency, with a PF value of up to 0.95, which is cost-effective; the other is a constant voltage with constant current power supply, which has stable performance, but low efficiency and high cost.
There are two types of LED panel lights, direct type and side light.
Side-emitting panel lights have the advantages of light weight and thin body, convenient installation and transportation, but the disadvantage is that they are easy to emit unevenly; the advantages of direct-lit panel lights are sufficient brightness and cost control advantages, but the disadvantages are inevitable glare, dark areas, and body It is heavy and relatively inconvenient for transportation and installation.
The price of side-emitting LED panel lights is more expensive than that of direct-type lights, because the technology of side-emitting LED panel lights is relatively complicated, which is determined by the product structure of side-emitting LEDs. Side-emitting LED panel lights are more expensive than direct-type technology and craftsmanship. All are complicated, which makes it difficult to control the product yield and product uniformity.
LED panel luminaires have a very soft light-emitting method. At present, the commonly used side light-emitting method, the light emitted from the surface of the lamp body is very uniform, so that the light emitted is not glaring at all. Used in various fields, it can effectively eliminate glare.
LED panel lights are gradually becoming the best product to replace traditional grille lamp panels in the LED era with their good uniformity of illumination, higher CRI, uniform and soft light, and comfort. They will be used in schools, hospitals, hotels and other indoor lighting fields. There will be more and more room for development.
