摘要： An LED light source device and an illumination device using the same, including vehicle lighting devices, can have a light weight and thin profile and can form a desired light distribution pattern while employing a simple configuration. The light source device can include a plate shaped light guide member made of a material that is transparent in a visible range. The light guide member can have a front surface serving as a light emitting surface and having a plate shape, and a rear surface having a luminance control element for controlling a luminance distribution on the light emitting surface. A point or linear light source facing towards an end surface of the light guide member can be provided. The luminance control element controls light reaching the element from the end surface of the light guide member and configures the luminance distribution on the light emitting surface, the luminance distribution being obtained by reducing a light distribution pattern to be projected (and in some cases horizontally and vertically reversing the pattern).

摘要： A reflecting plate in form of dual half-ellipses comprises a first ellipse having a first focal point and a second focal point, and a second ellipse having a first focal point and a second focal point. The first ellipse and the second ellipse commonly share the first focal point. A cross-section of the reflecting plate is designed in such a form that the dual half-ellipses are aligned with each other, and that contours of the first ellipse and the second ellipse are divided by a straight line, which includes the commonly shared first focal point and the other focal points. The reflecting plate encloses the line light source by the dual half-ellipses and reflects a light from the line light source toward the diffusion plate arranged above by specular reflection and by diffused reflection. As a result, uneven brightness is eliminated at the boundary of the reflecting plate designed in form of dual half-ellipses.

摘要： A vehicle lamp can include a light source unit including a light guide plate with a light emission surface, and a point or line light source opposed to one end face of the light guide plate. The light guide plate can be made of a transparent plate-like material. A convex projection lens can be configured to focus light emitted from the light source unit and project the light forward in a direction of light illumination. The light guide plate can have a prism array on a rear surface thereof extending with a serrated cross section from the one end face to the opposite end face of the light guide plate, and in a direction parallel with the end face. The prism array can include a plurality of prism surfaces, with each prism surface being obliquely formed so that when light enters the light guide plate from the light source side and impinges thereon, a substantial amount of the light can be totally reflected into small angles of incidence to the emission surface. The projection lens can be disposed such that a focus thereof on a light source unit side is located on the light emission surface of the light guide plate.

摘要： The disclosed subject matter includes providing a surface light source device using a plurality of different color light-emitting chips that can emit light with uniform color and a LCD unit having the same qualities. The surface light source device can include a light guide having a light incoming surface and a light-emitting surface, and light sources including the light-emitting chips located adjacent the light incoming surfaces. The light-emitting surface can include a light-mixing area that is spaced a distance L away from the light incoming surface, and the widest interval between the adjacent light-emitting chips is configured to be L/27 or less. Light emitted from the light sources can generate a mixture light with very little color variability in the light-mixing area, and the light can be emitted from the light-emitting surface other than the light-mixing area. Therefore, the LCD unit that includes a LCD located toward the light guide can illuminate the display with uniform color light.
