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. The projector includes a lighting unit and a lens unit; the lighting unit includes a first white light source and a second white light source whose center lines ofthe outgoing lights are perpendicular to each other, a mirror, and a light stick; the light incident surface of the light stick faces the first white light source, the light stick is disposed on theoutput light path of the first white light source, and the axis of the light stick is parallel to the center line of the outgoing light of the first white light source; the mirror is disposed on the output light path of the second white light source for reflecting the outgoing light of the second white light source to the light incident surface of the light stick; and the lens unit includes a collimating mirror, a meniscus lens, a biconcave lens, and a double convex lens which are arranged coaxially along the center line of the outgoing light of the light stick successively. The invention canenhance the light passing ability 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...
