Problems solved by technology

[0002] At present, the projection system of the projector mostly uses a single bulb as the light source. The light beam generated by the light source is processed by the uniform light system and then transmitted to the display device. Due to the limitation of the power and size of the bulb, the projection brightness after using a single bulb projection Limited, cannot cope with the demand for high display brightness

Abstract

The invention discloses a projector which comprises a lighting unit and a lens unit, wherein the lighting unit comprises a first white light source, a second white light source, a reflecting mirror and a light bar, and the center lines of emergent light of the first white light source and the second white light source are mutually vertical; the in-light surface of the light bar faces to the first white light source, the light bar is arranged on an output light path of the first white light source, and an axis of the light bar is parallel to the center line of the emergent light of the first white light source; the reflecting mirror is arranged on an output light path of the second white light source and used for reflecting the emergent light of the second white light source to the in-light surface of the light bar; the lens unit comprises a collimating mirror, concave and convex lenses, a biconvex lens and a biconcave lens, which are coaxially and arranged along the center line of the emergent light of the light bar. The projector can improve the light passing capacity and improve the projection brightness.

Description

technical field [0001] The invention relates to the technical field of projection, in particular to a projector. Background technique [0002] At present, the projection system of the projector mostly uses a single bulb as the light source. The light beam generated by the light source is processed by the uniform light system and then transmitted to the display device. Due to the limitation of the power and size of the bulb, the projection brightness after using a single bulb projection Limited, unable to meet the demand for high display brightness. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a projector capable of enhancing the light transmission ability and improving the projection brightness. [0004] In order to solve the above-mentioned technical problems, a technical solution adopted by the present invention is to provide a projector, the projector includes an illumination unit and a lens unit, and the...
