Abstract:
In a light-source device (10) of this invention, integrated light emission intensity from 460 nm to 500 nm is higher than integrated light emission intensity from 415 nm to 460 nm in an emission spectrum of white light. This allows provision of a light-source device which emits white light easy on a human eye.
