A photo-therapy device emits photo-therapeutic radiation to treat. living tissue. The device incorporates an array of emitters, the photo emissions of which is dependent on their temperature. Temperature feedback is provided to a voltage supply that supplies current to the emitters, to regulate the voltage supply level and the temperature of the emitters. Additionally, the wavelength of the radiation is dependent on the temperature of the emitters, so the wavelength is moved closer to an optimum wavelength for absorption by the tissue by controlling the temperature of the emitters. Furthermore, the useful life of the emitters is extended by pulsing the emitters on and off by sequentially applying an activation signal to one group of emitters at a time. Also, the device can operate on a wide range of voltage input levels since it utilizes a switching regulator, which can convert a voltage level in the range to the level required to drive the array of emitters. The photo-therapeutic infrared light may be used to treat insect bites and to relieve headaches in human beings. The infrared light emitters may be incorporated into a mouthpiece for treating gum tissues.
