no. 1 Embodiment
[0063] This embodiment provides a light source device, which can be applied to the illumination of an endoscope or other equipment. Such as figure 1 As shown, the light source device includes a first light source module 1 , a second light source module 2 , a first light combining sheet 3 , a light intensity detection module 4 , a light source control module 7 and a light source drive module 8 .
[0064] Among them, the first light source module 1 is used to emit light of the first color transmitted along the first optical path, such as white light; the second light source module 2 is used to emit light of the second color transmitted along the second optical path, such as blue-violet light, that is The colors of the first color light and the second color light are different, and the directions of the first light path and the second light path are also different; the first light combining sheet 3 is located at the intersection of the first light path and the second light path, ...
no. 2 Embodiment
[0074] The difference between this embodiment and the above-mentioned embodiment is that, as figure 2 As shown, the first light source module 1 includes a first light source 11 for emitting light of a first color. The second light source module 2 includes a fifth light source 15 for emitting light of the second color. The first color light and the second color light respectively emitted by the first light source 11 and the fifth light source 15 can also be beam expanded and shaped by optical equipment, the optical equipment is a lens group, and the optical equipment can also be a converging lens and a converging lens. All optics.
[0075] Optionally, the first color light is white light, and the second color light is blue-violet light. Of course, the present invention is not limited thereto. In other embodiments, the first color light can also be yellow light, the second color light can also be blue light, etc., or the first color light can also be red, green and blue light...
no. 3 Embodiment
[0083] The difference between this embodiment and the above-mentioned embodiment is that, as Figure 4 and Figure 5 As shown, the first light source module 1 includes a second light source 12 , a third light source 13 , a fourth light source 14 and a first light combining assembly 21 . Similarly, the second light source module 2 includes a fifth light source 15 for emitting light of the second color; but not limited thereto, the first light source module 1 can also be two light sources of different colors, four different In the case of multiple light sources such as light sources of different colors, the second light source module 2 may also include two light sources of different colors, three light sources of different colors, and the like.
[0084] Wherein, the second light source 12 is used to emit the first light; the third light source 13 is used to emit the second light; the fourth light source 14 is used to emit the third light; the colors of the first light, the seco...
