Abstract

The invention relates to a light merging device which comprises a first color selective mirror, a second color selective mirror and a third color selective mirror, wherein the second color selective mirror is arranged on a first side of the first color selective mirror and forms an included angle with the first color selective mirror, the third color selective mirror is arranged on a second side of the first color selective mirror, the second side of the first color selective mirror faces back to the second color selective mirror, and the third color selective mirror is approximately parallel to the second color selective mirror. The second color selective mirror and the third color selective mirror are mutually staggered for a distance along the first color selective mirror.

Description

【Technical field】 [0001] The present invention relates to a light combining device, and more particularly to a light combining device with a dichroic mirror. 【Background technique】 [0002] figure 1 It is a schematic diagram showing a conventional light combining device 100 . Such as figure 1 As shown, the light combining device 100 includes a first dichroic mirror 102 (dichroic mirror) and a second dichroic mirror 104 arranged crosswise. The blue light IB can be reflected by the first dichroic mirror 102 and pass through the second dichroic mirror 104, the red light IR can be reflected by the second dichroic mirror 104 and pass through the first dichroic mirror 102, and the green light IG can pass through the first dichroic mirror 102. The color mirror 102 and the second dichroic mirror 104 can achieve the effect of turning the color light from different directions to be output along the same direction. [0003] please refer again figure 2 The enlarged schematic diagr...
