What's the difference between back-emitting LED panel lights and side-emitting LED panel lights?
The side-emitting panel lamp adopts the light guide plate technology, and the light guide plate dot is designed according to the arrangement of the lamp beads on the LED lamp plate and the light emitting angle of the lamp beads, so that the light can pass through the light guide plate and achieve the effect of uniform brightness. The brightness is low, generally within 3000lm, and the specification is 595 * 595; Can be used in some places with low ceilings. Thin, the thickness is within 15mm. The surface uniformity is poor, and the brightness uniformity is as high as 0.85. If not handled properly, there will be obvious bright edges around. The workshop has high cleanliness, poor process control and low yield (mainly due to dust causing bright spots on the light guide plate).
