specific Embodiment approach

[0052] refer to figure 2 and Figure 4 , as a specific implementation of the optical path system provided by the present invention, there are at least three monochromatic light sources 1, the light processing components 2 are distributed along a preset path, and the light combining element 3 includes a dichroic mirror 302 and a first reflector 303 . A plurality of dichroic mirrors 302 are provided, and a plurality of dichroic mirrors 302 are successively arranged on the light-emitting side of the adjacent light processing assembly 2, and the difference between the number of the light processing assembly 2 and the dichroic mirror 302 is one; the first reflecting mirror 303 It is arranged on the light exit side of the light processing component 2 at the other end of the preset path, and is used to reflect the light emitted by the corresponding light processing component 2 .

[0053] The dichroic mirror 302 located at one end of the preset path is used to transmit the light em...

Abstract

The invention provides a light path system and a projector, and belong to the field of projection equipment. The projector comprises monochromatic light sources, light processing assemblies and lightcombining elements. The number of the monochromatic light sources is multiple, and the monochromatic light sources emit light of at least two colors. The multiple light processing assemblies are in one-to-one correspondence with the multiple monochromatic light sources, and the light processing assemblies are used for enabling light rays of the monochromatic light sources to form images; the lightcombining elements are in one-to-one correspondence with the light processing assemblies, and the light combining elements are used for receiving light emitted by the light processing assemblies andcarrying out light mixing processing. According to the light path system and the projector provided by the invention, a complex light path structure of color separation first and then color combination in a traditional light path system is not needed, the number of optical elements is reduced, the structure of the light path system is simplified to a great extent, the situation of excessive lightloss is avoided, meanwhile, a dark field can be set for each path of light, and the contrast ratio is improved.

Description

technical field [0001] The invention belongs to the technical field of projection equipment, and more specifically relates to an optical path system and a projector including the optical path system. Background technique [0002] A projector is a mechanical device that restores the image and sound recorded on a film with a screen and a loudspeaker. However, there are many optical elements in the optical system of the traditional projector, which cause more light loss during the light transmission process, so the optical system of the projector needs to be simplified. Contents of the invention [0003] The object of the present invention is to provide an optical path system to solve the technical problem in the prior art that there are many optical elements in the optical path system, resulting in more light loss during light transmission. [0004] In order to achieve the above object, the technical solution adopted by the present invention is to provide an optical path sy...
