Description of the invention: [Technical field of the invention] The present invention is an endoscope light source module structure with a light-emitting diode, in particular, an inner view of a light-emitting diode used for endoscope illumination Mirror light source module structure. ', [Prior Art] The use of endoscopes in conjunction with optical fibers allows the endoscope to directly detect lesions in the patient's body in a non-invasive manner, and to correctly and immediately transmit images of the lesions from the body. . Generally, it can be applied to several kinds of light sources of endoscopes. Since the performance and brightness of the light-emitting diodes are constantly improving, and the light-emitting diode is a cold light source, it will not generate high heat when used for a long time. The problem, therefore, the light-emitting diode will replace the 4-lamp lamp and become a new choice for the endoscope light source. However, when the length of the fiber used in the endoscope increases, the transmission of light in the fiber will cause breakage, so that the light extraction efficiency decreases with the length of the fiber, resulting in insufficient light intensity at the end of the fiber to achieve illumination. In order to achieve sufficient illumination of the Brahman, more than a few LEDs are needed. However, while increasing the number of light-emitting diodes used, it also increases the volume of the light source mode in the overall endoscope. The volume that causes the cost of the endoscope to increase is also limited. Therefore, how to increase the size of the light source module without changing the volume of the light source module can reduce the limitation of the fiber length application. A light source I is disclosed in U.S. Patent No. 6,832,849, "Light Dissipation Device, Light Source Device, Light Dispersion Early 7L, and Optical Connection Structure", which is used to provide a light source in the form of a beam, and the light source device includes: _ light source material group, which is composed of a plurality of fiber bundles or glass tubes and a single or a plurality of light-emitting diodes, and a casing, which is coated with a first light source lens and a second: direction light exiting Inside. The first light source lens is configured to enable the light source to guide the light emitted by the light-emitting body to be parallel and to the same mother light. The second source lens is used to cause refraction from the first source light source and to be concentratedly projected into the light source guiding unit.仃 Ο , , , , , , , , 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前 先前However, when there are a plurality of light-emitting diodes in the light source module, each of the light-emitting diodes and the surface of the light-emitting diode are not the same, and the same lens combination is used on the light-emitting path of the light-emitting module. Therefore, it is possible that the secret of the diode may not be obtained the most efficient efficiency of the overall light source module. ❹ [Summary of the Invention] The invention of the invention is a structure of an endoscope light source module with a light-emitting diode. The source is a light-emitting diode as a (four) mirror light source, and an optical fiber connector is used. . Also set the lens group and the mirror group so that each can be concentrated; The light that is emitted can increase the efficiency of the light to the fiber and the amount of the light source. Therefore, it is possible to provide an adequate illumination of the endoscope without increasing the number of endoscopes and the volume.

Convex lens 31. Since the convex lens 31 has the effect of collecting light, the light emitted from the light source module can be concentrated. When the light source module is composed of a plurality of light emitting diodes 20, for example, two or three light emitting diodes 20 are used. The first lens group 30, the second lens group 50, and the third lens group composed of the plurality of convex lenses 31 can be made by the plurality of convex lenses 31. After 70 or the fourth lens group 80 12 .201000064, it is gathered into a light beam. As shown in FIGS. 9 and 10, the first lens group 30, the second lens group 50, the third lens group 70, or the fourth lens group 80 may be formed by arranging at least one convex lens 31 and at least one concave lens 32, for example, one. The convex lens 31 is formed by alternately arranging three concave lenses 32. The lenticular lens 31 can condense the light and the concave lens 32 to diverge the light, so that the light emitted by each of the light-emitting diodes 20 in the light source module passes through the first lens composed of the corresponding concave lens 32 and the convex lens 31. After the group 30, the second lens group 50, the third lens group 70, or the fourth lens group 80, they can be gathered to form a light beam. Therefore, by the arrangement of the plurality of convex lenses 31 or at least one convex lens 31 and at least one concave lens 32 in the first lens group 30, the second lens group 50, the third lens group 70 or the fourth lens group 80, it is possible to gather each The light emitted by the LEDs 20 thus produces a collecting/concentrating effect, which makes the light more concentrated and enhances the light intensity of the endoscope light source module 10. © <Third Embodiment> Fig. 11 is a cross-sectional view showing an embodiment of an endoscope light source module structure 10 of the present invention. As shown in FIG. 11 , the embodiment is an endoscope light source module structure 10 having a light emitting diode, comprising: a fourth light emitting diode 24; a fifth lens 90; and an optical fiber connection. 60. The fourth light-emitting diode 24 is used as a light source of the endoscope, and the fourth light-emitting diode 24 is thermally coupled to a heat sink 25 to help the fourth light-emitting diode 24 to dissipate heat. 13.201000064 The fifth lens 90 is attached to the fourth light emitting diode 24. Further, the fifth lens 90 is fixedly coupled to the light-emitting surface of the fourth light-emitting diode μ by optical glue. The fifth lens 90 can be a convex lens 31. The light condensing effect of the convex lens 31 can cause the light emitted by the fourth light emitting diode to be concentratedly projected onto the optical coupling surface of the optical fiber connector 60. The fiber optic connector 60 is optically coupled to the light path of the fifth lens 90. By the arrangement of the optical fiber connector 6〇, the light emitted by the fourth LED ❹24 can pass through the fifth lens 9〇 and the fiber connector, and can be coupled to the optical fiber to provide an image of the endoscope. Lighting source.
