摘要： A vehicle light can prevent or suppress uneven luminance chromaticity or uneven intensity distribution of light caused by reflection of blue laser beams emitted from a laser light source and reflected by the surface of a metal plate located around fluorescent material. The vehicle light can include a metal plate, a fluorescent material provided on a surface of the metal plate. The fluorescent material can serve as a light source for emitting light beams as a result of excitation by a blue laser beam. A laser light source can be configured to emit the blue laser beam to be incident on the fluorescent material. A reflection suppressing member can be provided to cover the surface of the metal plate around the fluorescent material and can be configured to suppress the reflection of the blue laser beam emitted by the laser light source.

摘要： A substrate has first and second edges disposed in parallel and a principal surface connecting the first and second edges. An active layer is formed on the principal surface. A ridge-like region is disposed on the active layer along a path interconnecting a point on the first edge and a point on the second edge. The ridge-like region is made of semiconductor material having a refraction index smaller than a refraction index of the active layer, and defines a waveguide. The path is disposed along the principal surface and includes a first region on the side of the first edge and a second region on the side of the second edge. A first angle is taken between a normal to the first edge directing toward the principal surface and the first region. A second angle smaller than the first angle is taken between a normal to the second edge directing toward the principal surface and the second region. Electrodes inject current in a region of the active layer along the path.

摘要： A light diffusion sheet receives light fluxes radiated from a light radiating element at a first plane of the light diffusion sheet and scatters or diffracts the received light fluxes, and radiates the scattered or diffracted light from an opposite second plane. A light distributing member distributes the light radiated from the second plane of the light diffusion sheet along some direction. A light radiating device is provided which has a relatively large light beam spot.
