LED therapeutic device

A light emitting diode (LED) therapeutic device, comprising:

• a top case having a first end and a second end opposite to the first end;
• a light assembly embedded in an interior space of the top case and comprising:
• a lens coupled to the first end of the top case;
• a LED assembly close to the lens and comprising three visible light LEDs and two infrared LEDs, wherein the three visible light LEDs have wavelengths of 470 nm, 630 nm, and 660 nm, and the two infrared LEDs have wavelengths of 850 nm and 940 nm;
• and
• a reflector assembly coupled to the LED assembly and comprising five segments laterally connected to one another and oriented toward the lens, with each of the LEDs disposed in an opening within one of the five segments;
• a controller electrically coupled to the light assembly and configured to control the light assembly to emit an irradiance of 100-140 mW/cm2 when the LED therapeutic device is in contact with skin;
• a switch assembly coupled to the controller;
• a bottom case removable coupled to the second end of the top case;
• and
• a power supply electrically coupled to the controller and embedded in an interior space of the bottom case.
