Problems solved by technology

[0007] However, if figure 2 As shown, the joints of the first optical filter 11 and the second optical filter 12 and the first optical filter 11 and the third optical filter 13 are bonded by dispensing glue, resulting in two joints D
Since the refractive index of the joint D will affect the direction of light travel, the part of the first image beam R', the second image beam B' and the third image beam G' passing through the joint D will be deflected by the principle of refraction , thus affecting the image qualit

Abstract

The invention discloses a light converging module of a projector, which comprises a substrate with a plurality of insertion structures, a first light filter and a second light filter. One end of the first light filter and one end of the second light filter are inserted into the different insertion structures of the substrate respectively, and the first light filter and the second light filter are arranged on the substrate. The projector using the light converging module comprises a plurality of imaging modules. The imaging modules receive three kinds of color light to correspondingly generate a first image beam, a second image beam and a third image beam respectively. The light converging module is arranged on a transmission path of the image beams. The first light filter is used for reflecting the first image beam, and the second and third image beams penetrate the first light filter. The second light filter is used for reflecting the second image beam, and the first and third image beams penetrate the second light filter; therefore, the three image beams are converged to form a projection beam.

Description

technical field [0001] The invention relates to a light combining module of a projector, in particular to a fixing structure of the light combining module. Background technique [0002] Projectors are widely used in meetings, teaching, training and various business presentations. According to the display technology, projectors can be divided into cathode ray tube (Cathode Ray Tube, CRT) projector, digital light transmission (Digital Light Processing, DLP) projector, liquid crystal panel (Liquid Crystal Display, LCD) projector and liquid crystal silicon substrate (Liquid Crystal Display) projector. Crystal on Silicon (LCOS) projectors, LCD and LCOS projectors are currently the mainstream products. Selecting a projector is nothing more than paying attention to its projection quality, image quality, weight, lamp life and other indicators, and the projected light must be able to achieve high brightness and high stability, and the projected image must be able to achieve high res...
