Abstract:
A light source device is provided. The light source device comprises a semiconductor light-emitting element; and a wavelength conversion member for converting a wavelength of a light emitted from the semiconductor light-emitting element. The semiconductor light-emitting element has a light-emitting peak wavelength of not less than 380 nanometers and not more than 420 nanometers. The light emitted from the semiconductor light-emitting element has a light energy density of not less than 0.2 kW/cm2. The wavelength conversion member contains at least one fluorescent substance selected from the group consisting of a (Sr1-x,Bax)3MgSi2O8:Eu2+ (0≦x≦1) fluorescent substance, a (Y1-y,Gdy)3(Al1-z,Gaz)5O12:Ce3+ (0≦y≦1, 0≦z≦1) fluorescent substance, and an Eu3+-activated fluorescent substance. The light source device has a high output and a high light-emitting efficiency.
