LED panel light with its illuminance uniformity, display higher, light uniformity, comfort and other features, is widely used in offices, schools, hospitals, shopping malls, home and other places, to become the LED era to replace the traditional grille lamp plate the best products.
LED panel lamp using a luminous uniform reflective panel and sealed design, LED Surface Panel Light with efficient light guide plate, and aluminum alloy materials. The luminous effect is even, the illumination is higher.
LED panel light type thin, heat dissipation function is complete, low power, less heat.
LED panel light can be adjusted according to different needs and changes in the environment light color, not only without radiation and dazzle the production, LED Surface Panel Light and can protect eyesight, light color more moderate.
In LED panel lamp, LED light source is a kind of high hardness resin luminous body rather than tungsten wire glass and so on, it is not easy to damage, LED Surface Panel Light so its anti-vibration force is relatively high, the environment temperature adaptability is strong.
LED panel lamp can be controlled by the external controller for various dynamic programs, which can regulate the color temperature and adjust the shading degree.
At the same time, LED panel lamp lighting technology is a green lighting technology, the product does not contain mercury, waste less, the manufacturing process is almost non-existent pollution; Semiconductor lighting has the characteristics of recyclable and recyclable, LED Surface Panel Light which plays an important role in the sustainable development of economy and society.
The structure of LED panel lamp mainly includes frame, diffusion plate, guide plate, lamp bead, driving power supply, aluminum base plate and other parts.
1. Frame: Frame strength affects durability
The frame is an important part of the panel light, and the high strength frame makes the panel lamp more durable. The frame of the LED panel lamp uses different material, LED Surface Panel Light its heat dissipation performance is also dissimilar. According to statistics, the current panel lamp frame materials are mainly aluminum alloy, steel, PC, A6063, aluminum, steel and other materials.
2. Diffusion PLATE: Different material transmittance
The effect of the diffusion plate is to disperse the light of the guide plate evenly, also can play the role of the fuzzy dot, the material that uses mainly has acrylic, PC, PS and so on.
It is understood that acrylic transmittance in 92%, PC for 88%, PS probably 80%, acrylic material transmittance is higher than PC, and low cost, while its anti-aging performance is weak, but PC material price expensive, but anti-aging performance is strong.
3. Light Guide PLATE: The effect of the plate is very big
The effect of the guide plate is to reflect the light in the direction of the guide plate perpendicular to the direction of the transparent plate, and reflected by reflective paper to reflect the light on the back of the panel light. In this process, but also to reduce the light attenuation as much as possible, in general, LED Surface Panel Light the light efficiency of the guide plate depends largely on the design of the DOT, followed by the selection of plates.
4. Power supply: High efficiency of constant current power supply mode
LED lighting has two types of driving power mode, one is constant current power supply, this mode of high efficiency, pf value of up to 0.95, cost-effective; LED Surface Panel Light the other is constant voltage with constant current power supply, stable performance, but low efficiency, high cost.
