The invention discloses a wireless power supply small night lamp. The wireless power supply small night lamp comprises an independent spherical lamp body and a base. A wireless electric energy radiating circuit and a groove for containing the small night lamp are formed in the base, a wireless energy receiving circuit, an energy storage and an LED lamp body are fixed to a support in the sphericallamp body, a resonance coil of the wireless electric energy radiating circuit in the base rightly faces a containing cavity, that is, the resonance coil of the wireless electric energy radiating circuit in the base can rightly face the spherical lamp body, and when the spherical lamp body is arranged in the containing cavity in the base, charging can be conducted on the spherical lamp body throughwireless electric energy transmission. When a user needs to go to the bathroom at night, only the spherical lamp body needs to be grabbed, and after a vibration switch in the spherical lamp body detects shaking, the energy storage is controlled to output electric energy to drive the LED lamp body to achieve illumination; and the user carries the spherical lamp body to go to the bathroom, illumination can be provided all the way, and therefore the inadaptation feeling caused to the user when an indoor illuminating lamp is turned on is avoided.
