摘要: A vehicle light can improve the visibility (noticeability) for pedestrians, roadside obstructs, other vehicles and the like in actual traffic environments. The vehicle light can be configured to project light beams with a predetermined white color, and can include a light source with a color temperature range of 4500 K to 7000 K. The light source emits light beams including four color light beams represented by four coordinate values of predicted colors including red, green, blue and yellow in the a* b* coordinate system corresponding to the CIE 1976 L*a*b* color space. The four coordinate values in the a* b* coordinate system can be encompassed by respective circle areas having a radius of, for example, 5, and each having center coordinate values of (41.7, 20.9) for red, (−39.5, 14.3) for green, (8.8, −29.9) for blue and (−10.4, 74.2) for yellow, for example.

摘要: 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.

摘要: 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.

摘要: 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 be identical. 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.
