Abstract
A lighting device is disclosed in the present disclosure. The lighting device includes a support assembly, an illuminant assembly, and a switch assembly. The illuminant assembly is connected to the support assembly and capable of being rotated to the support assembly. When the illuminant assembly is rotated to a position at which an angle between the illuminant assembly and the support assembly is less than or equal to a first angle threshold, the switch assembly turns to an on-state. In this way, the lighting device has a function of a switch.
