Abstract: The present disclosure provides a meteor projection structure, which includes at least one polygonal reflecting wheel, at least one laser device, at least one light-permeable sheet and at least one motor. At least one side of the polygonal reflecting wheel is provided with a reflecting surface, a light emitted by the laser device is first reflected by the reflecting surface, and then emitted by the light-permeable sheet, wherein the light-permeable sheet intersects with an emergent light path; the motor is connected with the polygonal reflecting wheel through a transmission mechanism. A meteor lamp is further provided, which includes a housing and the meteor projection structure as described above. In the present disclosure, the motor drives the polygonal reflecting wheel to rotate; when a laser emitted by the laser device passes through the rotating polygonal reflecting wheel.

Abstract: A lamp projecting a starry sky is provided. The lamp projecting the starry sky includes at least one beam generator, a reflecting member with uneven and irregular reflecting surface, a first motor, and at least one first lens. The first motor is connected to the reflecting member through a connecting shaft, the reflecting member is driven to rotate when the first motor rotates, a light beam generated by the beam generator irradiates onto a first side of the reflecting member along an incident light path, and a light beam emitted from the reflecting member forms a moving and layering nebula projection after passing through the at least one first lens. In the lamp, after passing from the reflecting member, the light beam is magnified by the lens, so that the generated starry sky will not be too bright and dazzling, which effectively enhances the layering sense of the starry sky.

Abstract: A lamp projecting a starry sky is provided. The lamp projecting the starry sky includes at least one beam generator, an interference filter configured to produce nebula effect, a reflecting mirror, and at least one first lens, the at least one beam generator is placed on a first side of the interference filter, the reflecting mirror is placed on a second side of the interference filter, the at least one first lens is located on an emergent light path of the interference filter; a light beam emitted from the interference filter forms a moving and layering nebula projection after passing through the at least one first lens. In the lamp, after multiple refractions, reflection and refraction, the light beam is magnified by the lens.
