| 20090196061 | VEHICLE LIGHT AND METHOD - A vehicle cornering light can improve the visibility in a diagonally front area of the vehicle without increasing the luminous intensity of the cornering light (or light source thereof). The cornering light that is provided at or near a front corner of a vehicle and is configured to emit light for illuminating a diagonally front area of the vehicle can include a light source that can emit light with a color temperature of from 3700K to 7000K. The cornering light can emit light for illuminating a lateral area ranging from 60° to 75° with respect to the longitudinal direction of the vehicle. The light source can be composed of a first light source configured to emit light for illuminating an area partly overlapping, or adjacent to, an illumination area of the headlight of the vehicle, and a second light source configured to emit light for illuminating an area partly overlapping, or adjacent to, the illumination area of the first light source. The color temperatures of the headlight, the first light source, and the second light source are sequentially changed to be higher in this respective order. | 08-06-2009 |
| 20100232173 | VEHICLE HEADLIGHT - The disclosed subject matter includes a projector headlight using a plurality of optical units for a low beam with a high visible/visual quality. Each of the optical units can include a plurality of LED devices and a projector lens. The projector lens can include a light-emitting surface including a reflex function and a reflex surface including a light incoming surface that is located on the opposite side of the light-emitting surface. The LED devices can be located adjacent the light incoming surface, and the optical units can be located so that angles between optical axes of adjacent optical units can become substantially a same angle. Thus, the projector headlight can form various favorable light distribution patterns by changing curvature factors of the light-emitting surface and the reflex surface of the projector lens in each of the optical units and by changing the angles between the optical axes of the adjacent optical units. | 09-16-2010 |
| 20100321948 | Vehicle Light - A vehicle light can prevent the generation of glare light due to the reflection of light from a connecting surface surrounding a reflecting surface when a lens body including the reflecting surface and the connecting surface surrounding the reflecting surface is used and light emitted from an LED light source enters the lens body. The vehicle light can include a light source and a lens body. The lens body can include optical surfaces including the reflecting surface configured to form a predetermined light distribution pattern, and connecting surfaces that shape and define a structure of the lens body by connecting the optical surfaces, but that do not engage in the formation of the light distribution pattern. The connecting surface surrounding the reflecting surface can reflect part of incident light from the light source to a direction that is different from the direction by the reflecting surface and is directed to any one of connecting surfaces. One of the connecting surfaces can receive the light reflected by the connecting surface and project the light therethrough. | 12-23-2010 |
| 20100321949 | Vehicle Light - A light, and particularly a vehicle light, can prevent a reflected image of a resin injection trace (reflected in an adjacent connecting surface surrounding a reflecting surface) from being observed through a projecting surface, thereby preventing deterioration of appearance of the light. The light can include a light source and a lens body having a resin injection trace by injection molding. The lens body can include, as its surface, optical surfaces including an incident surface, a reflecting surface, and a projecting surface that are configured to form a predetermined light distribution pattern. Connecting surfaces that shape and define a structure of the lens body can connect the optical surfaces, and can be configured so as not to engage in the formation of the light distribution pattern. The incident surface can be a lens surface that can receive light from the light source to allow the light to enter the lens body. The reflecting surface can reflect the light from the light source toward the projecting surface so as to form the light distribution pattern. The projecting surface can be a lens surface that can receive the light directly from the light source and the light reflected by the reflecting surface, and project the same. The adjacent connecting surface of the connecting surfaces can be configured so as not to generate a light path from the resin injection trace via the connecting surface to the projecting surface. | 12-23-2010 |
| 20110085333 | VEHICLE LIGHT - A vehicle light can include an optical system for controlling a light distribution pattern, and the optical system is a light guide (being a lens body having an inner reflecting surface). The vehicle light can project illumination light with a low bean light distribution pattern. The vehicle light can include an LED light source and a lens body serving as a light guide. The lens body can include a light incident surface, a reflecting surface, and a light exiting surface. The LED light source can have a rearmost end light emitting point from which light beams are emitted to form a bright-dark boundary line. Among the light beams, perpendicularly incident light beams not subjected to refraction can be projected toward the bright-dark boundary line while obliquely incident light beams being subjected to refraction can be corrected to be directed in a lower angular direction than the bright-dark boundary line to be mixed with the other light beams emitted from other light emitting points of the LED light source, thereby preventing the color shading of illumination light. | 04-14-2011 |
| 20110085343 | VEHICLE LIGHT - A vehicle light can include a light emitting diode (LED) serving as a light source and an optical system for controlling a light distribution pattern of the light beams from the LED light source utilizing a light guide (such as a lens body having an inner reflecting surface). The vehicle light can project illumination light with a low beam light distribution pattern. The vehicle light can include an LED light source and a lens body serving as a light guide. The lens body can include a light incident surface, a reflecting surface, and a light exiting surface. The LED light source can have a rearmost end light emitting point from which light beams are emitted to form a bright-dark boundary line. Among the light beams, perpendicularly incident light beams not subjected to refraction can be projected toward the bright-dark boundary line while obliquely incident light beams that are subjected to refraction can be corrected to be directed in a lower angular direction than the bright-dark boundary line and to be mixed with the other light beams, thereby preventing color shading of illumination light from the vehicle light. | 04-14-2011 |
| 20110235357 | VEHICLE HEADLIGHT - A vehicle headlight can include a semiconductor light source and a heat sink to radiate heat developed from the light source. The headlight can include a mounting base board mounting the light source and attached on a radiating base plate of the heat sink. At least one of a bottom surface of the mounting base board and the radiating base plate can include a concave portion in which a depth thereof is deeper than a maximum particle size of an inclusion of a thermal conductive viscous material that spreads in the concave portion. The light source can be located at a prescribed position in an accurate fashion without a positional misalignment while the heat developed from the light source can efficiently radiate via the heat sink. Thus, the disclosed subject matter can provide headlights including a radiation structure having a high radiating performance and positional accuracy for the light source. | 09-29-2011 |
