摘要： A light source device has a light shielding member having an aperture, a light source arranged on one side of the light shielding member, and a converging member arranged relatively with respect to the light source and the light source to thereby converge light emitted from the light source in the aperture or in a vicinity of the aperture. Another type of light source device has a single light source, and a converging member for converging light from the light source to thereby distribute the light to at least two points. Still another type of light source device has a light source, and a reflecting mirror arranged to enclose a side of a light emission direction of the light source, the reflecting mirror reflecting light emitted from the light source in a direction except the light source so that the light is radiated outside.

摘要： A headlight having an ellipse group reflecting surface as a main reflecting surface and a projection lens further includes a second reflecting surface, a third reflecting surface, and a ring-shaped lens. Direct light from a light source reaching to a space between the main reflecting surface and the projection lens is reflected by the second reflecting surface backward. The reflected light from the second reflecting surface is further reflected by the third reflecting surface, and then is adjusted with the ring-shaped lens. Light directly emitted from the light source and being ineffective in the conventional headlight can be collected using the second and third reflecting surfaces, and forwarded in an illumination direction by passing through the ring-shape lens such that the shape of the light is controlled to provide an appropriate shape, thereby contributing to the formation of light distribution characteristics and increase in the light intensity.

摘要： A LED symbol signal with LEDs arrayed to correspond to a desired symbol. Light from the LEDs is directed onto corresponding optical segments of a multiple collimating zone element and directed into a forward direction/distribution. A mask defines the desired symbol. The optical segments and or a diffusion surface on the cover or multiple collimating zone element(s) diffuses the display aspect, obscuring the individual LEDs. A diameter of the optical features of the diffusion surface is smaller than a diameter of the optical segments. The LED symbol signal may be configured for retrofitting into an incandescent lamp signal housing.

摘要： The present invention relates to a multi-angle reflector for use in a backlight unit. The back light unit comprises a plurality of lamps, a multi-angle reflector and a diffuser. The multi-angle reflector comprises a plate and a plurality of reflecting protrusions. The plate has a top surface toward to the lamps. The reflecting protrusions are respectively disposed on the top surface of the plate. Each reflecting protrusion has a reflecting surface. The reflecting surfaces have a plurality of reflecting angles corresponding to the top surface of the plate so that the light from lamps are adapted to reflect to the diffuser according to the reflecting angles. Therefore, according to the invention, the reflecting angles of the reflecting surfaces on the reflecting protrusions can be adjusted so as to suit to various actual conditions. The lights are uniform and the utility of the lights is improved. Because the reflecting protrusions are small, the reflector can be made into a thin type. For the whole structure, the thickness of the backlight unit is decreased.

摘要： A vehicular lamp which radiates a light by indirect illumination using a plurality of LED light sources which has a thin structure while providing sufficient light output to the front of the lamp, even in the case where the lamp is mounted in a wrap-around portion of the vehicle body. Respective Fresnel lenses which form light from respective LED light sources into parallel light fluxes are arranged so as to align the directions of the parallel light fluxes upward, and the parallel light fluxes are then reflected toward the front of the lamp by a reflector. The reflector is separated into sub-reflectors for every area which the parallel light fluxes from the respective Fresnel lenses strike, and the sub-reflectors are arranged in a stepped configuration extending in a lateral direction of the reflector from the front of the lamp toward the rear of the lamp. Accordingly, it is possible to form the reflector so as to wrap around to the rear of the lamp while the reflected light from the respective sub-reflectors is radiated toward the front of the lamp.

摘要： A zoom strobe device is provided with a light emitting unit, which includes a light source and a reflector and a light collecting lens that collects the light emitted by the light emitting unit. The light emitting unit and the light collecting lens are movable relative to each other in a direction of an optical axis of the light collecting lens. The light collecting lens is configured such that a light emitting unit side surface has a positive power, and a surface opposite to the light emitting unit side surface (i.e., the object side surface) has a negative power. The light collecting lens has a positive power as a whole.

摘要： A sheet-like light source device comprising a plurality of bar-shaped light sources, a diffusing plate for diffusing light emitted from the light sources, and a reflecting plate capable of mirror reflecting the light emitted from the light sources to the diffusing plate side. The reflecting plate is provided in a position opposite to the diffusing plate with respect to the light sources. The reflecting plate has at least one convex portion formed in parallel with the light sources in a space between the two adjacent light sources. It is possible to decrease or remove shield printing which has conventionally carried out over the diffusing plate, thereby enabling manufacture of a back light having a high efficiency.
