Abstract

The utility model provides a panel lamp. The panel lamp comprises an LED light source, a light guide plate and a diffusion plate, wherein the LED light source comprises a plurality of independent controllable light sources, the light of the LED light source enters the light guide plate, and the diffusion plate is arranged on one side of the light guide plate and is parallel to the light guide plate. According to the panel lamp, due to the fact that the independent controllable light sources are adopted, mixing of the light emitted by the independent controllable light sources is achieved through the guide light plate, dodging is then carried out on the mixed light through the diffusion plate, and finally even light can be emitted; the current of a power circuit can be adjusted to adjust the light emitting intensity, light in different colors at different color temperatures can be obtained after light mixing, and the brightness of the emitted light can also be adjusted.
