Lighting device for projecting a starry pattern

A lighting device projecting starry pattern, comprising:

• a light emitting assembly comprising at least one first non-coherent light source, a light-reflection medium, a first condensing lens, a driving device, a driving gear and a driven gear, wherein
• an inner wall surface of the light-reflection medium is formed by mutually connecting a plurality of irregular light-reflection surfaces;
• the first non-coherent light source is arranged in the light-reflection medium;
• the first condensing lens is arranged above the light-reflection medium;
• the driving gear is connected to the driving device;
• and the driven gear is arranged on the light-reflection medium and is engaged with the driving gear to drive the light-reflection medium to rotate;
• wherein the lighting device projecting starry pattern further comprises a film assembly comprising at least one second non-coherent light source, a condensing piece, a film sheet, a dial assembly and a second condensing lens;
• wherein the second non-coherent light source is arranged in the condensing piece;
• the film sheet is fixed on the dial assembly;
• the dial assembly is arranged above the condensing piece, and is provided with a projection hole corresponding to a pattern of the film sheet in a light emitting direction of the condensing piece;
• and the second condensing lens is arranged above the projection hole.
