Patent number: 8506146Abstract: A vehicle head lamp includes: a light source; a reflector that reflects light emitted from the light source; a condenser lens that irradiates the light reflected by the reflector forward; and a shade that blocks part of the light reflected by the reflector to obtain a desired light distribution. The shade includes a main shade that has an opening for passing overhead sign light irradiated forward and upward and a sub-shade that is provided so as to be inclined rearward and downward from an upper edge of the main shade in order to obtain a cut line of the light distribution, and the reflector has an OHS reflection area used to project part of the reflected light toward a lower surface of the sub-shade and that allows the light reflected on the lower surface to pass through the opening of the main shade as the OHS light.Type: GrantFiled: January 11, 2011Date of Patent: August 13, 2013Assignee: Koito Manufacturing Co., Ltd.Inventors: Masao Kinoshita, Akinori Matsumoto, Tomoyuki Moritani, Takahiro Suzuki

Patent number: 7695176Abstract: A projection-type vehicle headlamp includes a lamp body, a front cover forming a lamp housing together with the lamp body, a light projection unit accommodated inside the lamp body, and a cover extending in a forward direction from the light projection unit. A louver is formed on a portion of the cover where light from the light projection unit is irradiated so as to allow irradiated light to pass through the louver.Type: GrantFiled: September 17, 2007Date of Patent: April 13, 2010Assignee: Koito Manufacturing Co., Ltd.Inventors: Sumito Ohtaki, Kohji Shimakura, Noriyuki Konagai, Akinori Matsumoto, Tomoyuki Moritani

Patent number: 7350948Abstract: A vehicle headlamp includes a projection lens which is placed on an optical axis extending in a front and rear direction of a vehicle, a light source which is placed behind a rear focal point of the projection lens, a reflector which reflects light emanated directly from the light source in a forward direction and toward the optical axis, and a light-dark boundary forming plate which is placed between the projection lens and the light source. The light-dark boundary forming plate extends rearward and obliquely downward from a vicinity of the rear focal point of the projection lens, and a light-dark boundary forming portion is formed on a front end portion of the light-dark boundary forming plate. The light-dark boundary forming portion shields a part of the light reflected from the reflector and forms a cut-off line of a light distribution pattern.Type: GrantFiled: December 28, 2006Date of Patent: April 1, 2008Assignee: Koito Manufacturing Co., Ltd.Inventors: Naohi Nino, Takayuki Iwaki, Tomoyuki Moritani, Akinori Matsumoto

Patent number: 7008093Abstract: A first shade 32 is properly moved to vertically shift the position of a cutoff line, and furthermore, a lighting unit 20 is properly tilted in a vertical direction to displace a whole light distribution pattern in the vertical direction. Consequently, a light irradiation is carried out with a light distribution pattern at an irradiation angle corresponding to a vehicle traveling situation. In that case, a second shade 34 is properly moved to form a dark portion in a central part on the lower end of the light distribution pattern in a predetermined size if necessary. Consequently, the amount of a light irradiation on a short-distance region can be controlled finely, and a road surface on this side can be prevented from becoming too bright in a high-speed travel and a light reflected by the road surface which causes a glare can be prevented from being generated in a rain travel.Type: GrantFiled: April 22, 2004Date of Patent: March 7, 2006Assignee: Koito Manufacturing Co., Ltd.Inventors: Kiyotaka Fukawa, Tomoyuki Moritani, Masahito Naganawa

Patent number: 6695466Abstract: In a headlamp having a single filament bulb or discharge bulb, there is provided a movable shade that can appear from a reflection mirror located above the single filament bulb. In a usual condition, the movable shade is pulled at the back of the reflection mirror located above the single filament bulb. Then, a light emitted from the single filament bulb is condensed by the reflection mirror and irradiates a very long distance thereby to make a high-speed traveling possible. On the contrary, when it is rainy or foggy, the movable shade is protruded in the front of the reflection mirror. Then, a part of a light emitted from the single filament bulb is shielded by the movable shade, and the road surface in 20-40 m front of the vehicle is darkened thereby to reduce surface reflection from the road surface.Type: GrantFiled: October 11, 2001Date of Patent: February 24, 2004Assignee: Koito Manufacturing Co., Ltd.Inventors: Masahito Naganawa, Tomoyuki Moritani, Akinori Matsumoto, Takayuki Iwaki
