Patent ID: 8628199

Claim:
A light source device comprising: a first excitation light generation section having a first solid-state light source array having first solid-state light sources adapted to generate a first excitation light, and a first collimating lens array having first collimating lenses disposed so as to correspond to the first solid-state light sources, and adapted to roughly collimate the excitation light generated by the first solid-state light sources; a second excitation light generation section having a second solid-state light source array having second solid-state light sources adapted to generate a second excitation light, and a second collimating lens array having second collimating lenses disposed so as to correspond to the second solid-state light sources, and adapted to roughly collimate the excitation light generated by the second solid-state light sources; an excitation light combining section adapted to combine the first excitation light and the second excitation light; a light collection optical system adapted to collect the first excitation light and the second excitation light combined by the excitation light combining section at a predetermined light collection position; and a fluorescence generation section located in a vicinity of the light collection position, and having a fluorescent layer adapted to generate a fluorescence from at least a part of the first excitation light and the second excitation light collected by the light collection optical system, wherein the excitation light combining section is adapted to transmit the first excitation light and reflect the second excitation light to thereby combine the first excitation light and the second excitation light with each other.
