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

Patent number: 7963665Abstract: A vehicle light having a plurality of LED light sources can be configured to be capable of preventing or suppressing emission of glaring light. An LED package with a plurality of LED light emitting elements can be provided. The vehicle light can include a plurality of LED light sources emitting light with a dominant wavelength that falls within a wavelength range of light that is emitted from an incandescent bulb and which has passed through a filter with a specified color. The respective dominant wavelengths can be different from one another. The LED package can include a plurality of LED elements emitting light that has a dominant wavelength which falls within a wavelength range of light that is emitted from an incandescent bulb and which has passed through a filter with a specified color. The respective dominant wavelengths can be different from one another.Type: GrantFiled: March 10, 2009Date of Patent: June 21, 2011Assignee: Stanley Electric Co., Ltd.Inventors: Takako Minoda, Shinichi Kojima, Hidetaka Okada

Patent number: 7959337Abstract: 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.Type: GrantFiled: January 26, 2009Date of Patent: June 14, 2011Assignee: Stanley Electric Co., Ltd.Inventors: Susumu Nakamura, Takako Minoda, Yasushi Kita, Norikatsu Myojin

Patent number: 7628508Abstract: An illuminating device able to easily visualize a pedestrian, etc. on a footway by the driver of an automobile is provided. The illuminating device has a footway side light source portion for irradiating light of spectral characteristics rich in blue-green color light to the footway, and a roadway side light source portion for irradiating light of spectral characteristics rich in green-red color light to a roadway. Further, the spectral characteristics of the light irradiated from the footway side light source portion are set such that a value Ip obtained by the following formula (1) is greater than a value IC obtained by the following formula (1) from the spectral characteristics of the light irradiated from the roadway side light source portion.Type: GrantFiled: September 25, 2007Date of Patent: December 8, 2009Assignee: Stanley Electric Co., Ltd.Inventors: Yasushi Kita, Shinichi Kojima, Takako Minoda, Naoko Takenobu
