Abstract:
The disclosure discloses a multi-source homework lamp comprising: a first lampshade and a second lampshade connected to a shaft, wherein the first lampshade and the second lampshade are rotatable around the shaft; main lights disposed inside each of the lampshades; and a control unit for controlling the luminance of the main lights and controlling the rotation of the first lampshade and the second lampshade, thereby controlling the angle between the two. In the multi-source homework lamp according to the disclosure, by a design of the two-piece main lights with the angle being variable, the illuminance is caused to be more uniform, and the illumination range and the illumination luminance of the homework lamp may be adjusted more conveniently.
