Apparatus for feeding light and heat

An apparatus for feeding light and heat comprising:

• a light source holder for a human body that can be fixed in contact with the human body, and has a cavity for the human body that is recessed from a side that contacts the human body;
• a light source for the human body that is installed in the cavity for the human body and emits light of near-infrared rays;
• a light source holder for temperature control, wherein a cavity for temperature control is formed from one side, wherein the light source holder for temperature control is formed of the same material as the light source holder for the human body, and wherein the cavity for temperature control has the same shape as the cavity for the human body;
• a light source for temperature control installed in the cavity for temperature control and emitting light of the same wavelength as the light source for the human body;
• a temperature sensor installed at the entrance of the cavity for temperature control of the light source holder for temperature control and covering the entrance;
• a power source that supplies a same power to the light source for the human body and the light source for temperature control;
• a temperature switch that is operated when subcutaneous temperature reaches a suitable temperature;
• and
• a controller that adjusts power supplied from the power source to the light source for the human body and the light source for temperature control based on a temperature measured by the temperature sensor,
• wherein the controller controls the power supplied to the light source for the human body and the light source for temperature control so that the temperature measured by the temperature sensor is maintained at the temperature when the temperature switch is operated.
