Abstract
The invention discloses a multi-spectral lighting method applied to minimally invasive surgery with an LED light source. The LED multi-spectral light source includes a housing, a power supply, a drive circuit board, an LED module, a heat-conducting substrate, a heat sink, a cooling fan, and an optical focusing lens group. , light guide, switch, touch screen control area and power input interface. The power supply and drive circuit board are located inside the casing, the LED module is packaged on the heat-conducting substrate, and the heat-conducting substrate is vertically installed inside the casing. One end of the heat sink is connected to the heat-conducting substrate, and the other end is connected to the cooling fan. The side of the substrate away from the cooling fan, the light guide is set in a horizontal direction, the end of the light guide away from the optical focusing lens group passes through the casing and extends outward, the switch is set on the outer wall of the casing, the touch screen control area is set on the side of the switch, the power supply The input interface is arranged on the side of the shell away from the switch; the drive circuit board, the LED module, the power supply, the cooling fan, the switch, the touch screen control area and the power input interface are electrically connected.
Description
technical field [0001] The invention relates to the field of multi-spectral light source design, and is typically applied to the light source for intelligent robot image recognition and medical image recognition. More specifically, the present invention provides a multi-spectral illumination method applied to minimally invasive surgery with an LED light source. Background technique [0002] Generally, the representative methods for realizing multi-spectral light sources are as follows: [0003] One is the method of coaxial conjugation of dichroic mirrors, such as the principle disclosed in CN201821575340.7, a multi-spectral light source system, "Each LED emits light of different wavelengths, and then passes through the dichroic mirror to make the light of different wavelengths The light is coaxially conjugated, so that it can be irradiated to the same position, and a fiber optic probe is installed at this position to export the light." The dichroic mirror of this method nee...
