Abstract

This invention relates to a self-rotation projection lamp. The self-rotation projection lamp comprises a machine shell and a projection device; the machine shell comprises a shell body and a support which is arranged in the shell body; the projection device is arranged in the shell body, and comprises a motor, a driving gear, a light-emitting unit, a gear set and a film roll set; the motor is arranged on the support and can drive the driving gear to rotate; the light emitting unit is arranged on the support; the gear set is rotationally engaged with the driving gear; and the film roll set is arranged on the gear set. When the self-rotation projection lamp is used for projection, the driving gear and the gear set are driven to rotate through the motor, the film roll set on the gear set is made to rotate, the light ray emitted out of the light-emitting unit can be projected into rotating patterns through the rotating film roll set, the interestingness of dynamic changing is achieved, theself-rotation projection lamp can be applicable to cheerful and lively holidays or party occasions, and the practicability of the self-rotation projection lamp is improved.

Description

technical field [0001] The invention relates to a self-rotating projection lamp, in particular to a self-rotating projection lamp which rotates a film sheet through gears to project a rotating pattern. Background technique [0002] Most of the machines used to project patterns on the market are projection lamps. The existing projection lamps include a casing, a light-emitting unit, a film, and a lens element. The casing has a projection port, and the light-emitting unit is located on the The inside of the casing and facing the projection port, the film sheet is arranged inside the casing and in front of the light-emitting unit, the lens element is arranged in front of the film sheet, when the projection When the lamp is projecting a pattern, the projection lamp projects a stationary pattern on a background. [0003] However, the patterns projected by the existing projection lamps are still, and there is no mechanism to rotate the film, so the projected patterns always prese...
