Abstract

The invention discloses a starry sky projection lamp, and belongs to the field of projection lamps. The starry sky projection lamp comprises at least one light beam generator, an interference sheet used for generating a starry cloud effect, a reflector and at least one first lens, the light beam generator is arranged at one side of the interference sheet, the reflector is arranged at the other side of the interference sheet, the at least one first lens is located on an emergent light path of the interference sheet, and a light beam emitted from the interference sheet passes through the at least one first lens to form a moving star cloud hierarchical projection. According to the starry sky projection lamp, the light beam is amplified through the lens after being refracted, reflected and then refracted for multiple times, so that the generated starry sky is not too bright and dazzling, the soft feeling of the pattern transition position is better, and the layering sense of the starry sky is effectively enhanced.

Description

technical field

[0001] The present invention relates to the field of projection lamps, in particular to a starry sky projection lamp and a nebula generation method used for the starry sky projection lamp. Background technique

[0002] The star projection lamp is a projection device that can produce dynamic nebula effects. It is often used in homes, cars, entertainment venues, etc. as ambient lights. Star projection lamps usually produce dynamic nebula effects by irradiating light beams on a rotating interference disk, and can even simulate actions such as stars blinking.

[0003] Chinese Patent Literature Publication No. CN101276523B discloses a projection device for producing a moving starry sky and cloud-like effects, including a device for producing cloud-like effects using at least one incoherent light source, and a device for producing motion-like effects using at least one coherent light source. Devices for the starry sky and devices for regulating and supplying elect...
