Abstract

The invention discloses an LED light source for medical endoscopic spectral staining illumination. The LED light source comprises an LED light source assembly, an LED driver, a combined controller, a power supply, a fan, an air pump, a light-guiding rod and a combined color lens; a white light LED has the wavelength of 400-780nm, a red light LED has the wavelength of 617-630nm, a green light LED has the wavelength of 520-530nm and a blue light LED has the wavelength of 450-460nm. The invention further discloses an illumination method. The illumination method comprises the following steps: mixing lights of the white light LED, the red light LED, the green light LED and the blue light LED; controlling the color temperature and the intensity of the white light LED, the red light LED, the green light LED and the blue light LED for illumination. During the application of a high-color temperature and high-color rendering index white light source used by a high-definition electronic gastrointestinal endoscope as well as an intelligently-arranged pigment spectral light source for special diagnosis to conventional endoscopic observation and treatment as well as early cancer observation and diagnosis of a digestive tract and other organs, needs are met.

Description

technical field [0001] The invention relates to a medical device, in particular to an LED light source used for spectral dyeing illumination of a medical endoscope. The invention also relates to an LED lighting method used for spectral dyeing lighting of medical endoscope. Background technique [0002] Traditional cold light sources for endoscopes are divided into halogen, xenon lamp, LED and other light source drive devices. Among them, the cost of the halogen lamp light source is relatively low, but because the color rendering index is not high, it can only meet the general endoscope lighting requirements. The color temperature and color rendering index of the xenon lamp light source It can basically meet the lighting needs of endoscopes, but its high cost, high energy consumption and short life also restrict its application in endoscopes. Although the current general LED lighting technology has made great progress, its color rendering index It is still difficult to meet ...
