Description

Multilayer refraction projection lamp

Technical Field

The utility model relates to a projection lamp of multilayer refraction belongs to projection lamp technical field.

Background

The projection lamp can provide soft light, makes the sleeping room become very comfortable silence, builds the ambient atmosphere of peaceful and peaceful, also can build very romantic atmosphere, for example the little night-light of multi-functional projection that chinese patent document CN202442171U disclosed. This kind of little night-light includes base, transparent circle and semi-transparent dull polish lid, is provided with the projection film of printing the pattern in the transparent circle, and the light that sends through the luminous body on the base throws to dull polish after passing through the projection film and covers to the shadow that throws out forms exquisite pattern on dull polish covers. Further, for example, chinese patent document CN206274151U discloses a superimposed dynamic pattern projection lamp, which includes a light emitting body, a rotating table assembly, a projection film and a printing film. The light that the luminous body sent sees through the projection film of continuous rotation, on the pattern mapping on the projection film printed film, superposes each other with the pattern on the printing film again, and the pattern that the stack produced can constantly change, forms dynamic pattern effect. The projection lamp can bring people a sense of beauty and comfort, but most of the improvement of the projection lamp in the market is on the pattern and color of the projection film, so that the type of the projection lamp is single. Thus current stage polyhedral refraction lamp shade can refract light through a plurality of refraction and produce the refraction effect of illusion-colour, does not have the lamp shade of this kind of structure to be applied to projection night-light technical field at present yet.
