Light therapy apparatus

A light therapy device comprising:

• bodies configured to be supported against a user's auricles;
• an earhole insertion member coupled to each body and configured to be inserted into the user's earhole, wherein the earhole insertion member is formed of a heat-resistant material in a tapered shape whose diameter gradually decreases toward the user's ear;
• a generator provided at a base portion of the earhole insertion member and configured to irradiate infrared light, wherein each generator comprises:
• a casing;
• and a plurality of LEDs disposed on one side of the casing, the plurality of LEDs comprising a main LED configured to irradiate far-infrared light and a plurality of sub LEDs configured to irradiate near-infrared light, wherein the main LED is disposed at a central portion of the casing and the plurality of sub LEDs are radially arranged around the main LED;
• a temperature sensor disposed on each body and configured to measure a temperature of the earhole insertion member or the generator;
• and
• a controller disposed on the bodies and configured to control the generator, wherein the controller is configured to stop irradiation of the generator when a measurement value of the temperature sensor is greater than or equal to a preset value.
