Medical endoscope, medical endoscope cold light source system, and temperature control system for medical endoscope cold light source system

Abstract

The invention provides a medical endoscope cold light source system comprising a power input interface, an LED source module and a cold light source control panel. The LED source module comprises an LED light-emitting chip, a junction temperature measurement sensor and a semiconductor refrigerator sheet, wherein the junction temperature measurement sensor is used for measuring junction temperature of the LED light-emitting chip in real time and the semiconductor refrigerator sheet is used for refrigerating the LED light-emitting chip. The cold light source control panel is electrically connected with the LED source module and drives the LED source module to operate so as to acquire real-time junction temperature of the LED light-emitting chip, measured with the junction temperature measurement sensor, and to compare to preset operating temperature; when the real-time junction temperature deviates the preset operating temperature, the semiconductor refrigerator sheet is controlled to operate. The system is capable of controlling the temperature of the LED light-emitting chip in real time according to life features of the LED light-emitting chip and dissipating heat through the semiconductor refrigerator sheet, has no influence on heat dissipation effect due to changes in ambient temperature, and allows the LED light-emitting chip to operate in the optimal state. The invention further provides a temperature control system and a medical endoscope.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a medical endoscope with life warning, a cold light source system of the medical endoscope and a temperature control system thereof. Background technique [0002] With the continuous advancement of high-brightness LED technology, the cold light source for endoscope with high-power LED light-emitting chip as the core in the field of medical endoscope light source has gradually begun to occupy the market dominated by tungsten-halogen lamps and xenon lamps. LED cold light source can effectively overcome the shortcomings of existing endoscopic light sources such as tungsten-halogen lamps and xenon lamps, and is favored by users for its many advantages such as high brightness, suitable color temperature, low heat generation, and long life. The theoretical life of LED cold light sources with mature technology can reach more than 50,000 hours. However, many endoscope cold li...

Problems solved by technology

Although the above heat dissipation methods can dissipate heat to a certain extent for the LED light-emitting chip, they are easily affected by the ambient temperature, especially when the temperature difference between the LED light-emitting chip and the environment is small, it is more likely to be severely restricted.
