Abstract
Official abstract text for this publication.
In an exemplary embodiment, a laser light source device includes a laser light source that emits laser light from a laser emission aperture. The laser light source device also includes a condenser lens disposed in front of the laser light source in a laser emission direction to collect the laser light. The laser light source device also includes a fluorescent member disposed in front of the condenser lens in the laser emission direction to receive the laser light collected by the condenser lens and to emit light of a different wavelength from that of the laser light. The laser light source device also includes a light guide that forms a light path of laser light from the laser light source to the condenser lens.
First claim
Opening claim text (preview).
What is claimed is: 1. A laser light source device comprising: a laser light source for emitting laser light through a laser emission aperture thereof; a condenser lens disposed in front of said laser light source in a laser emission direction to collect said laser light; and a light guide covering said laser emission aperture so as to guide said laser light, said light guide having a reflective surface, and said reflective surface extending from said laser light source to sai…
