摘要： A light source device includes: an excitation light source which generates excitation light; a phosphor wheel having a phosphor which is excited by the excitation light to generate fluorescent light; and a mirror which guides excitation light from the excitation light source to the phosphor wheel to emit the fluorescent light from the phosphor wheel as illumination light. The phosphor wheel further includes a diffusion/reflection portion which diffuses and reflects incident excitation light, and the mirror has a first region which reflects the excitation light and transmits the fluorescent light and a second region which transmits the fluorescent light and diffused excitation light. In the mirror, the fluorescent light transmitted through the first region and the fluorescent light and the diffused excitation light transmitted through the second region are used as illumination light.

摘要： A light source device includes an excitation light source that generates excitation light, a phosphor wheel including a phosphor segment that generates fluorescent light by excitation of the excitation light, and a mirror that guides the excitation light from the excitation light source to the phosphor wheel and emits the fluorescent light from the phosphor wheel as illumination light. The phosphor wheel further includes an anisotropic diffusion and reflection unit that diffuses and reflects incident excitation light such that an optical path for the incident excitation light and an optical path for the diffused excitation light after incidence of the excitation light are not overlapped. The mirror includes a first region that reflects the excitation light and transmits the fluorescent light and a second region that transmits the fluorescent light and the diffused excitation light which the anisotropic diffusion and reflection unit has diffused and reflected.

摘要： Provided is a light source device where the number of optical components is reduced without lowering an efficiency for light utilization. The light source device includes an excitation light source which generates blue laser light as excitation light, a phosphor wheel including a phosphor which is excited by the excitation light from the excitation light source to generate yellow fluorescent light, and a mirror which guides the excitation light from the excitation light source to the phosphor wheel and transmits the fluorescent light from the phosphor wheel, wherein the mirror includes a first region which reflects the excitation light and transmits the fluorescent light and a second region which transmits the fluorescent light and diffused excitation light which is diffused and reflected in the phosphor. The yellow fluorescent light and the diffused excitation light passing through the mirror are mixed to generate white light.

摘要： A vehicle lamp includes a phosphor which receives laser light (excitation light) emitted from a semiconductor light-emitting element to emit visible light, a reflector which reflects the visible light (illumination light) emitted from the phosphor forward, and an absorbing member which absorbs excitation light regularly reflected by a surface of the phosphor. A metal plate on which the phosphor is disposed to be inclined to cause the excitation light regularly reflected by the surface of the phosphor to be incident on the absorbing member. An upper end portion of the reflector is disposed at a position lower than a vertical position of the phosphor to prevent the regularly reflected excitation light from being incident on the upper end portion.
