The invention discloses a light emitting diode (LED) cold light source of an endoscope. A first support frame is installed at one end of a sealed outer shell and is located inside the sealed outer shell. The bottom of the first support frame is fixedly connected with a substrate. An LED is installed on one side of the substrate. A radiator is installed on the other side of the substrate. A lamp condenser lens set is installed at the hanging end of the support frame. A second support frame is installed at the other end of the sealed outer shell and is located inside the outer sealed shell. A secondary light-gathering optical lens set is installed at the hanging end of the second support frame. A fiber interface is installed in the sealed outer shell and is located in the bottom of the second support frame. An optical fiber is arranged in one end of the fiber interface in an inserted mode. An optical light ray receiving device is installed at the other end of the fiber interface. The LED cold light source of the endoscope has the advantages of being reasonable in design, simple in structure, high in lighting brightness, and small in amount of generated heat, and long in service life.
Description
technical field [0001] The invention belongs to the technical field of LED lighting and relates to an endoscope LED cold light source. Background technique [0002] With the progress of society and the development of science and technology, endoscopes are widely used in clinical or medical research as the most commonly used medical equipment, but traditional endoscope lighting sources have high heat generation, short light source life, frequent replacement, and Disadvantages such as insufficient lighting brightness.
