PROBLEM TO BE SOLVED: To provide light therapy equipment which suppresses raising of the temperature of light absorption filters by arranging the two or more light absorption filters between a light source and a light outgoing port and differentiating the respective wavelength regions of absorbing light by the two or more light absorption filters. SOLUTION: In the light therapy equipment where the light source 2 is arranged in a casing 1 and light of a prescribed wavelength outgoes from the light outgoing port 8 of the casing 1, a light-incident side filter 12 and a light outgoing side filter 13 of different wavelength ranges for absorbing light are provided between the light source 2 and the light outgoing port 8, and the light-incident side filter 12 absorbs light of a shorter wavelength side than the light outgoing side filter 13.
