Introduction to the Product Knowledge of Panel LED Lamp
Application Areas of LED Panel LED Lamp
LED panel LED lamp are widely used in offices, schools, hospitals, shopping malls, homes, and other places due to their good illumination uniformity, higher color rendering index, even and soft light, and comfort, replacing traditional grille lights in the LED era as the best product.
Product Structure of LED Panel LED Lamp
The structure of LED panel LED lamp mainly includes frame, diffuser, light guide plate, lamp beads, driver power supply, and aluminum substrate.
Frame: durability is affected by the strength of the frame
The frame is an important part of the panel light, and a high-strength frame makes the panel light more durable. Different materials are used for the edge frame of LED panel LED lamp, and their heat dissipation performance varies. According to statistics, the current frame materials for panel LED lamp mainly include aluminum alloy, steel, PC, A6063, aluminum-plastic, and steel materials.
Diffuser: different materials have different light transmittance
The diffuser's role is to evenly diffuse the light from the light guide plate and also to blur the dot. The materials used for it mainly include acrylic, PC, PS, etc.
It is understood that the light transmittance of acrylic is 92%, PC is 88%, and PS is about 80%. Acrylic has higher light transmittance than PC and lower cost, while its aging resistance is weak; PC material is expensive but has strong aging resistance.
Light guide plate: the plate has a great influence on the light efficiency
The light guide plate's role is to refract the light parallel to the direction of the light guide plate perpendicularly to the direction of the light guide plate, and reflect it out by the reflecting paper from the light guide plate to the back of the panel light.
In this process, light attenuation should be reduced as much as possible. Generally speaking, the light efficiency of the light guide plate depends largely on the dot design, followed by the choice of plate material.
Power supply: constant current power supply mode has high efficiency
LED lights have two driving power supply modes, one is a constant current power supply which has high efficiency with a power factor of up to 0.95, and high cost-performance; The other is a constant voltage with constant current power supply, which has stable performance, but low efficiency and high cost.
