PROBLEM TO BE SOLVED: To provide a small-sized and handy type phototherapy apparatus in which light emitting power is variable. SOLUTION: The device is composed of a handy type irradiation device including a filament light source 1 for emitting infrared rays of wavelength 600-1,800 nm through a light guide 23, and an electric power supply device for the filament light source. Electric power supply device has two modes, standard lighting mode (Ms) in which filament light source 1 is controlled to a predetermined standard electric current value, and modulated lighting mode (Mc) in which electric current is reduced in terms of the standard electric current value. In the modulated lighting mode (Mc), at the time of initial lighting, electric current amount is doubled. COPYRIGHT: (C)2006,JPO&NCIPI
