  • Patent number: 10955120
    Abstract: A lamp has a base, a transmission mechanism, and multiple light-emitting assemblies. The transmission mechanism is mounted on the base and is rotatable around a transmission axis. The light-emitting assemblies is mounted on the base and is connected to the transmission mechanism. Each light-emitting assembly is rotatable around a rotation axis which is nonparallel with the transmission axis. The light-emitting assemblies can be rotated through driving the transmission mechanism, so as to adjust lighting effects of the light-emitting assemblies and an appearance of the lamp. Not only the lighting effects can be adjusted according to a user's need, but also the appearance of the lamp can be changed to adapt the lamp to the environment where the lamp is disposed, such that the lamp of the present invention can be widely used.
