What is the difference between back-emitting LED panel lights and side-emitting LED panel lights?
Aug 30, 2021
The back light panel light is designed to use the LED light angle to make a reasonable LED spacing, and cooperate with the diffuser and the height of the lamp to achieve the ideal light mixing effect. Emphasis on high brightness, 595*595 specifications can reach 4000lm, high luminous efficiency product, replace the traditional grille lamp panel. Thicker, usually more than 45mm in thickness. The light output is relatively uniform, and the brightness uniformity can reach above 0.9. The process requirements are relatively simple.
The side-emitting panel light uses the light guide plate technology to design the light guide plate mesh points according to the arrangement of the LED lamp bead and the light-emitting angle of the lamp bead, so that the light passes through the light guide plate to achieve the effect of uniform brightness. The brightness is low, generally within 3000lm with 595*595 specifications; it can be applied to some occasions where the ceiling is low. Thinner, the thickness is within 15mm. The surface uniformity is poor, and the brightness uniformity is up to 0.85. If the treatment is not good, there will be more obvious bright edges around. The cleanliness requirements of the workshop are high, the process control is not good, and the yield rate is low (mainly dust causes the bright spots in the light guide plate).
The LED panel light is a high-end indoor lighting fixture. Its outer frame is made of aluminum alloy and anodized. The light source is LED. The design of the entire lamp is beautiful, simple and luxurious. It not only has a good lighting effect, but also brings people. The feeling of beauty.
The LED panel light has a unique design. The light passes through the light guide plate with high light transmittance to form a uniform plane luminous effect. The uniformity of illumination is good, the light is soft, comfortable and bright, which can effectively relieve eye fatigue. The LED panel light can also prevent radiation and will not irritate the skin of pregnant women, the elderly, and children.
