What you must know about panel lights

LED panel lamp is widely used in office, school, hospital, shopping mall, home and other places because of its good illumination uniformity, higher indication, uniform and soft light, comfort and other characteristics. It has become a better product to replace the traditional grid lamp panel in the LED era. The structure of LED panel lamp mainly includes frame, diffuser, light guide plate, lamp bead, driving power supply, aluminum substrate and other components.
1. Frame: the strength of the frame affects the durability
The frame is an important part of the panel lamp. The frame with high strength makes the panel lamp more durable. The frame frame of LED panel lamp uses different materials, and its heat dissipation performance is also different. According to statistics, the current frame materials of panel lamps mainly include aluminum alloy, steel, PC, a6063, aluminum plastic, steel and other materials.
2. Diffuser: different materials have different light transmittance
The function of the diffusion plate is to evenly disperse the light of the light guide plate, and also play the role of blurring the dot. The materials used mainly include acrylic, PC, PS, etc.
It is understood that acrylic transmittance is 92%, PC is 88%, PS is probably 80%, acrylic material transmittance is higher than PC, and the cost is low, and its anti-aging performance is weak. PC material is expensive, but it has strong anti-aging properties.
3. Light guide plate: the plate has a great influence on the light effect
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 refracted by the light guide plate to the back of the panel lamp is reflected by the reflective paper. In this process, the light attenuation should be reduced as much as possible. Generally speaking, the light efficiency of the light guide plate largely depends on the dot design, followed by the selection of the plate.
4. Power supply: constant current power supply mode, high efficiency

There are two driving power modes for LED lamps. One is constant current power supply, which has high efficiency, PF value up to 0.95 and high cost performance; The other is constant voltage and constant current power supply, which has stable performance, but low efficiency and high cost.
