Problems solved by technology

Therefore, the light emitted by some light-emitting diodes may not be used most effectively, reducing the light extraction efficiency of the overall light source module.
[0007] It can be seen that the above-mentioned existing light source device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Abstract

The invention relates to an endoscope light source module structure with light-emitting diodes, which comprises at least two first light-emitting diodes, at least two first lens sets, at least two reflector sets, a second lens set and a fiber connector, wherein each of the first lens sets is optically coupled one to one and arranged on a corresponding light-emitting path of the first light-emitting diode; each of the reflector set is optically coupled one to one and arranged on a corresponding light-emitting path of the first lens set; the second lens set is optically coupled and arranged on the light-emitting paths of the reflector sets; and the fiber connector is optically coupled and arranged on the light-emitting path of the second lens set. The light is transmitted in the fiber in form of beams, so the light loss rate can be reduced, the light source strength of the endoscope can be further promoted, and better illumination effect can be provided during diagnosis of the endoscope.

Description

technical field [0001] The invention relates to an endoscope light source module structure with light-emitting diodes, in particular to an endoscope light source module structure with light-emitting diodes applied to endoscope lighting. Background technique [0002] Through the combined use of the endoscope and the optical fiber, the endoscope can directly detect the lesion in the patient's body in a non-invasive manner, and can accurately and immediately transmit the image of the lesion out of the body. Generally, it can be used in several kinds of light sources for endoscopes. Because the performance and brightness of LEDs are constantly improving, and LEDs are cold light sources, they will not cause high heat when used for a long time, so they emit light. Diodes will replace halogen lamps and become a new choice for endoscope light sources. [0003] However, when the length of the optical fiber used in the endoscope increases, the transmission of light in the optical fib...
