Patent number: 8480270Abstract: A headlamp aiming system is configured to include: a lamp unit; an actuator configured to displace the light axis of the lamp unit; an imaging apparatus configured to acquire the information necessary for adjustment of the light axis; and an ECU configured to control the actuator. By imaging a light distribution pattern formed by lighting the lamp unit with the imaging apparatus, and by controlling the actuator by the ECU such that the deviation between the position of an attention point in a light distribution pattern, obtained from the imaged image information, and the position of a reference point that has been set beforehand becomes the minimum or zero, an attitude of the lamp unit is adjusted such that aiming of the lamp unit can be automatically performed in a self-contained manner.Type: GrantFiled: May 27, 2009Date of Patent: July 9, 2013Assignee: Koito Manufacturing Co., Ltd.Inventor: Kiyotaka Mochizuki

Patent number: 8157427Abstract: A vehicle headlamp is provided. The vehicle headlamp includes a light source which is configured to form an additional light distribution pattern which is formed above a cut-off line of a low-beam mode light distribution pattern; a vehicle detection device which is configured to detect a presence of a front running vehicle; a road position detection device which is configured to detect an existing area of a road ahead; and a control unit. The control unit acquires information from the vehicle detection device and the road position detection device and, when the existing area includes a non-detectable area which is outside of a detectable area of the vehicle detection device, controls the light source to reduce an illuminance of the additional light distribution pattern.Type: GrantFiled: March 11, 2009Date of Patent: April 17, 2012Assignee: Koito Manufacturing Co., Ltd.Inventors: Kiyotaka Mochizuki, Naoki Tatara

Patent number: 7901121Abstract: The light distribution of a vehicle headlamp can be changed between various modes, including a basic mode and a motorway mode. In the basic mode, shaded region changeover means block a high light intensity region, and deflection control means controls a lamp optical axis Lx to a straight travel direction. In the motorway mode, the shaded region changeover means does not block the high light intensity region, and the deflection control means controls deflection of the lamp optical axis to a host vehicle lane side. A light distribution in which the high light intensity region faces a far distance ahead of the host vehicle lane can be obtained, and the host vehicle lane is brightly illuminated without dazzling a driver of a preceding vehicle or an oncoming vehicle. Accordingly, illumination suited to the motorway mode during high speed and medium speed travel can be achieved.Type: GrantFiled: October 24, 2008Date of Patent: March 8, 2011Assignee: Koito Manufacturing Co., Ltd.Inventors: Hirohiko Ohshio, Kiyotaka Mochizuki

Patent number: 7758218Abstract: A vehicular headlamp including a light amount control device that controls the amount of light from at least two of a plurality of light source units each having a light-emitting element as the light source. The light amount control device performs a contrasting control of the lamp to increase the amount of light from at least one of the light source units and decrease the amount of light from the other light source unit, thus enhancing the visibility by increasing the amount of light from one light source unit and enhancing the brightness in an area that the unit illuminates, and decreasing the amount of light from the other light source unit that illuminates an area where visibility is required less, lowering the power consumption.Type: GrantFiled: July 3, 2007Date of Patent: July 20, 2010Assignee: Koito Manufacturing Co., Ltd.Inventors: Kiyotaka Mochizuki, Takashi Hori, Naohisa Tatara

Patent number: 7618173Abstract: A vehicle headlamp includes a lamp 110 having shade switching means 140 for providing a desired light distribution pattern by blocking a portion of light emitted from a light source. Light distribution pattern switching controlling means controls the shade switching means 140 in response to receipt of an instruction of switching a light distribution pattern of the lamp. Leveling means 130 controls deflection of an optical axis of the lamp in a vertical direction. The light distribution pattern switching controlling means controls the shade switching means 140 such that a cut line is formed by a height substantially the same as that of a cut line of high beam when an instruction of switching to a light distribution pattern of “remote optically recognizing beam” is received and controls the leveling means 130 such that the cut line is formed by a height of a cut line requested for “middle beam”.Type: GrantFiled: February 13, 2007Date of Patent: November 17, 2009Assignee: Koito Manufacturing Co., Ltd.Inventors: Atsushi Sugimoto, Kiyotaka Mochizuki, Naohisa Tatara

Publication number: 20080192496Abstract: A vehicle lamp system includes lamps RHL and LHL. The lamp system can switch at least to a low beam distribution and a motorway light distribution. A light distribution switching control portion CONT for switching the light distribution based on operational information of the vehicle switches to the low beam distribution when it is determined that the vehicle speed is less than a predetermined speed in the motorway light distribution and a predetermined light distribution switching condition is satisfied. If presence of an obstacle is confirmed so as to apply a deceleration, it is possible to prevent the obstacle from being undetected by switching to the low beam distribution. Thus, it is possible to reliably keep away from the obstacle, thereby ensuring stable operation.Type: ApplicationFiled: February 4, 2008Publication date: August 14, 2008Applicant: Koito Manufacturing Co., Ltd.Inventors: Kiyotaka Mochizuki, Naohisa Tatara

Patent number: 6535222Abstract: A graphic method for preparing a surface map used to synthesize a masking layer. The proposed structures on a semiconductor surface are mapped as trapezoidal figures on a numerical grid. The first grouping step groups trapezoids into a plurality of groups based on Ymin, and groups are then internally sorted based on Xmin. A to-be-judged group is selected. A intra-group judging step uses a trapezoid as a to-be-judged figure in order of sorting, and trapezoids sorted after the to-be-judged trapezoid as a to-be-compared figures successively in order of sorting, determining if there is intersection and if so incrementally moving the to-be-compared figure, and repetitively executing an intersection judgment processing until there is no intersection or until the to-be-compared figure disappears.Type: GrantFiled: March 27, 2000Date of Patent: March 18, 2003Assignee: Shinko Electric Industries Co., Ltd.Inventor: Kiyotaka Mochizuki
