What's the difference between back-emitting LED panel lights and side-emitting LED panel lights?

The difference between back-emitting LED panel lights and side-emitting LED panel lights lies in the different lighting modes. Back-emitting panel lamp is to design reasonable LED spacing by using LED luminous angle, and achieve ideal light mixing effect with diffuser and lamp height. Emphasis on high brightness, with 595*595 specifications up to 4000lm, high efficiency products, replacing the traditional grid lamp panel. Thick, usually more than 45 mm thick. The light is uniform, and the brightness uniformity can reach above 0.9. The process requirements are relatively simple.

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).
