What are side-emitting panel lights and direct-emitting panel lights
Side-emitting panel lights mainly use light guide plate technology, and design the light guide plate dots according to the arrangement of the LED lamp bead and the light-emitting angle of the lamp bead, so that the light can achieve the effect of uniform brightness through the light guide plate. The direct light panel light uses high-brightness LEDs as the light source and adopts a direct light distribution design, which has the characteristics of high light efficiency, uniform light output, safety and reliability, low power consumption and long life.

The side-emitting panel light is better or the direct light is better, which can be seen from the following aspects:
1. Light effect. Compared with the side-emitting panel light, the direct-emitting panel has high lighting efficiency. The light emitted by the LED light source is directly irradiated through the diffuser. There is no other cut-off between the light source and the diffuser, so there is no light transmission. The lumen value of the whole lamp It is also relatively high. The light source of the side-emitting panel is not in the same direction as the light-emitting surface of the lamp, and the overall light efficiency is low.
2. Heat dissipation. The quality of heat dissipation will directly affect the life and light attenuation of the lamp. Among the side-emitting panel lights and the direct-emitting panel lights, the side-emitting panel lights have ideal heat dissipation. The position of the LED light source is different from the direct-lit type. The light source is attached to the outer bracket, and the outer bracket participates in the entire heat dissipation process, thereby solving the heat dissipation problem.
3. Weight. Compared with the direct-emitting panel light, the position of the side-emitting LED light source is different from the direct-down type. The light source is attached to the outer bracket, and the outer bracket participates in the entire heat dissipation process, thereby solving the heat dissipation problem.
4. Cost. The side-emitting flat-panel lamp increases the cost due to the addition of the light guide plate.
