The light source can project an enlarged matrix light on the reflector via the imaging lens. The reflector can include a matrix reflex surface having horizontal curvatures. Each of the horizontal curvatures of the reflex surfaces arranged in columns can be configured such that the corresponding column light is extended gradually in a wider range as the corresponding column light approaches from a central column light toward both edge column lights. Accordingly, a magnification of light projected from the reflector can become gradually large as approaching from the central column toward both edge columns. Thus, the disclosed subject matter can provide vehicle headlights that can form favorable light distribution patterns for a low beam and a high beam having a bright central portion in a wide range of a smooth light distribution pattern.Type: GrantFiled: March 24, 2011Date of Patent: May 14, 2013Assignee: Stanley Electric Co., Ltd.Inventors: Takashi Sato, Masafumi Ohno

Patent number: 8439537Abstract: A vehicular lighting fixture unit can include a projector lens placed on an optical axis extending in a vehicle front-rear direction. A light-emitting element can be placed between the projector lens and a rear-side focal point of the projector lens at a position lower than the optical axis so as to emit light substantially vertically upward. A phosphor can be placed so as to be closer to a vehicle rear side than the rear-side focal point. A first reflecting surface can reflect the light from the phosphor so as to condense the light toward the optical axis. A second reflecting surface can be placed substantially vertically above the light-emitting element at a position at which the second reflecting surface does not block the reflected light from the first reflecting surface. The second reflecting surface can reflect the light from the light-emitting element toward the phosphor.Type: GrantFiled: September 8, 2011Date of Patent: May 14, 2013Assignee: Stanley Electric Co., Ltd.Inventors: Yoshiaki Nakazato, Yoshiaki Nakaya

Patent number: 8408766Abstract: The present invention relates to surfacing material which may emit radiation in response to exposure to a given light source. Such surfacing material may be polymeric based, and e.g., fiber based, and may be used in relatively low-light areas, including low-light areas as applied to vehicular applications. The fiber-based or molded materials may emit radiation in response to exposure to a selected light source and may be used in relatively dimly lit areas. The materials may also provide a visible contrast to other objects located adjacent their surface which do not emit radiation. Optical brighteners and luminous particles may be included in the materials to make them luminous.Type: GrantFiled: November 7, 2007Date of Patent: April 2, 2013Assignee: International Automotive Components Group North America, IncInventors: Ernie Wilson, Mitchell Whitesell, Sean Simmons

Patent number: 8398282Abstract: A vehicle front lighting assembly, or headlight assembly, that includes one or more variable tint electrowetting elements overlying a portion of the assembly lens surface. The variable tint electrowetting element is configured to operate to a transparent state whereby the hue of light passing therethrough is not changed, and a tinted state where the hue of light passing therethrough is changed. Alternatively, the variable tint electrowetting element is configured to operate to the tinted state and an opaque state where light is blocked from passing through the electrowetting element. The assembly may use light emitting diodes (LED) as an alternative to more conventional light sources.Type: GrantFiled: May 12, 2011Date of Patent: March 19, 2013Assignee: Delphi Technologies, Inc.Inventors: Frederick F. Kuhlman, Dwadasi H. R. Sarma, Nasser Lukmani

Patent number: 8388200Abstract: 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.Type: GrantFiled: February 4, 2011Date of Patent: March 5, 2013Assignee: Stanley Electric Co., Ltd.Inventors: Shinichi Kojima, Masafumi Ohno, Yasushi Kita, Takako Minoda, Naoko Takenobu, Susumu Nakamura, Norikatsu Myojin, Takashi Sato
