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.
Claims20
A lamp projecting a starry sky, comprising:
- at least one beam generator;
- an interference filter, configured to produce a nebula effect;
- a first motor connected to the interference filter through a connecting shaft;
- the beam generator is placed on a first side of the interference filter, a light beam generated by the beam generator irradiates onto the first side of the interference filter along an incident light path;
- a reflecting mirror, placed on a second side of the interference filter;
- after the interference filter is irradiated by the light beam, a light in the light beam passes through the interference filter after being subjected to 1) a reflection, or 2) a refraction, a reflection and a refraction in sequence, or 3) a refraction, multiple reflections and a refraction in sequence under action of the interference filter and the reflecting mirror;
- at least one first lens, located on an emergent light path of the interference filter;
- the light beam emitted from the interference filter forms a moving and layering nebula projection after passing through the at least one first lens.
