Problems solved by technology
[0002] Existing cold light sources used in endoscopic lighting in the field of medical diagnosis mainly use halogen lamps or xenon lamps as illuminants, which have low light utilization efficiency, high heat, and serious energy waste
[0003] like figure 1 The structure of the existing cold light source is shown. The cold light source 01 is powered by AC220V. The cold light source 01 leads the light beam through the optical fiber 02 and transmits it to the endoscope 03. The disadvantage of this structure is that the cold light source is large in size and complex in structure. And it needs to be exported by optical fiber, which is cumbersome to use

Embodiment
[0023] see figure 1 , an LED hand-held cold light source, comprising a main structure handle 1, an LED light source 2 arranged in the handle 1, a power switch button 6 arranged on the surface of the handle 1, a time / brightness display button 7, a time setting button 8 and a brightness adjustment button 9. It also includes a charging base 4 and a power adapter 5. The upper part of the handle 1 is directly connected to the endoscope 3. The LED light source 2 is composed of LED lamp beads and LED chips. The LED lamp beads are installed on the handle 1 and the endoscope 3. At the docking point, the optical fiber connection part in the previous cold light source structure is omitted, making it smaller in size and more compact in structure, and it is convenient for the light emitted by the LED light source 2 to be directly used for endoscope illumination, with minimal light loss and easy to use. convenient.

The invention discloses an LED handheld cold light source comprising a handle, an LED light source, a controller, a charging holder and a power adapter, wherein the LED light source and the controller are arranged in the handle; the charging holder provides direct current; and the controller is connected with a chip arranged inside the LED light source through a circuit. The LED light source is located at the upper part of the handle, the upper part of the handle is directly in butt joint with an endoscope, the lower part of the handle is arranged in the charging holder, the surface of the handle is provided with a plurality of functional buttons, and the functional buttons are respectively connected with the controller arranged inside the handle through a circuit. The surface of the charging holder is provided with an interface connected with the power adapter, and the charging holder is hollow to ensure that the lower part of the handle can be conveniently inserted to the charging holder, thus, a safe and reliable supporting point is provided for a whole device, and electric energy can also be replenished in time to ensure normal operation of the device. The LED handheld cold light source has the advantages of high lighting efficiency, low temperature, small size, compact structure, more convenience in operation due to the adoption of a handheld type and long service life.
Description
technical field [0001] The invention relates to a cold light source used for lighting in the medical field, in particular to an LED hand-held cold light source. Background technique [0002] Existing cold light sources used in endoscopic lighting in the field of medical diagnosis mainly use halogen lamps or xenon lamps as illuminants, which have low light utilization efficiency, high heat, and serious energy waste. [0003] Such as figure 1 The structure of the existing cold light source is shown. The cold light source 01 is powered by AC220V. The cold light source 01 leads the light beam through the optical fiber 02 and transmits it to the endoscope 03. The disadvantage of this structure is that the cold light source is large in size and complex in structure. And it needs to be exported by optical fiber, which is cumbersome to use. Contents of the invention [0004] In order to overcome the above-mentioned defects in the prior art, the present invention provides a LED h...
