摘要： A light source device can include a solid-state light source configured to emit blue light as excitation light and a phosphor section which is excited by the excitation light from the solid-state light source and which emits fluorescent light longer in wavelength than the light emitted from the solid-state light source. In the light source device, a wavelength selective member configured to transmit the excitation light from the solid-state light source and to reflect the fluorescent light from the phosphor section can be provided between the phosphor section and the solid-state light source. The size of the wavelength selective member can be less than the size of the phosphor section which can be greater than the size of the excitation light spot irradiated with the solid-state light source.

摘要： A light source can include: a light source that emits light of a predetermined wavelength within a wavelength region covering the wavelength of ultraviolet light and that of visible light; and a wavelength conversion layer containing a fluorescent material of at least one type that is excited by excitation light from the fixed light source to emit fluorescent light of a wavelength longer than that of light emitted from the fixed light source. The fixed light source and the wavelength conversion layer can be spaced from each other. The light source device can employ a reflection system of extracting at least fluorescent light from an incident surface of the wavelength conversion layer through which excitation light from the fixed light source enters the wavelength conversion layer. The wavelength conversion layer can have a surface structure with depressions or projections.
