| 摘要 |
This invention discloses a light therapy apparatus which has a curing effect by means of light irradiation and which less stimulates an irradiated portion. The light therapy apparatus according to this invention has a light source (2) and a spectrofilter (5) for substantially blocking, of spectrum components of light emitted from the light source (2), those other than a spectrum component within a predetermined range, and radiates light transmitted through the filter. The spectrofilter (5) has characteristics of transmitting a first wavelength component having a wavelength of about 280 nm to 400 nm and a second wavelength component having a wavelength of not less than about 700 nm, while substantially blocking a wavelength component at least between the first and second wavelength components.
