Reflective dynamic projector and starry sky lamp

摘要

A reflective dynamic projector includes a light projection device. The light projection device includes a reflective element with a reflective surface, a plurality of first light sources, and a first driving unit. There are bump textures arranged on the reflective surface which make the reflective surface to be a diffuse reflection surface. The reflective surface surrounds the plurality of first light sources and each of the plurality of first light sources is arranged towards the reflective surface; or an outer surface of the reflective element is the reflective surface, the plurality of first light sources surrounds the reflective element, and each of the plurality of first light sources is arranged towards the reflective surface. The first driving unit is connected with the reflective element or the plurality of first light sources and drives the reflective element or the plurality of first light sources to rotate.
