20100110710 | VEHICLE HEADLAMP - A vehicle headlamp with improved vibration proof of a movable reflector is provided. The vehicle headlamp has: a holder; an upside movable reflector and a downside movable reflector; light sources; and a drive unit. The drive unit is made up of a motor and a drive force transmission mechanism. The drive force transmission mechanism rotates the upside and downside movable reflectors in reverse directions, respectively. As a result, the vehicle headlamp can improve the vibration proof of the upside and downside movable reflectors. | 05-06-2010 |
20100110711 | VEHICLE HEADLAMP - A vehicle headlamp is provided with: a fixed reflector having reflecting surfaces, a respective one of which is made of a parabola-based free curved face; movable reflectors having reflecting surfaces, a respective one of which is made of a parabola-based free curved face; and semiconductor-type light sources, a respective one of which has a light emitting chip shaped like a planar rectangle. When the movable reflectors are positioned in a first location, a light distribution pattern for low beam is obtained on the reflecting surfaces of the fixed reflector. When the movable reflectors are positioned in a second location, light distribution patterns for high beams are obtained on the reflecting surfaces of the fixed reflector and the movable reflector. As a result, the vehicle headlamp enables downsizing, weight reduction, power saving, and cost reduction. | 05-06-2010 |
20100165653 | VEHICLE HEADLAMP - A vehicle headlamp is provided with semiconductor-type light sources, lenses, a reflector, light shading members, prism members, and a switching device. When the light shading members are positioned in a first location by means of the switching device, a light distribution pattern LP for low beam, having one or more cutoff lines, is illuminated. In addition, when the prism members are positioned in the first location by means of the switching device, a light distribution pattern HP for high beam is illuminated. As a result, the vehicle headlamp can achieve downsizing, weight reduction, power saving, and cost reduction. | 07-01-2010 |
20100165654 | VEHICLE HEADLAMP - A vehicle headlamp is provided with: a main reflector having a convergent reflecting surface; a semiconductor-type light source; a projecting lens; an auxiliary reflector having a parabolic reflecting surface; a shade and a light shading member that are structured integrally with each other; and a switching device. By means of the switching device, the shade and light shading member, which are structured integrally with each other, are switched and positioned in a first location and a second location, thereby allowing light distribution patterns for high and low beams to be switched and illuminated toward a forward direction of a vehicle. As a result, the vehicle headlamp becomes capable of achieving downsizing, weight reduction, power saving, and cost reduction. | 07-01-2010 |
20100194276 | VEHICLE HEADLAMP - A vehicle headlamp is provided with: a fixed reflector having reflecting surfaces made of parabola-based free curved faces; movable reflectors having reflecting surfaces made of parabola-based free curved faces; and semiconductor-type light sources having light emitting chips shaped like a planar rectangle. When the movable reflectors are positioned in a first location, a light distribution pattern for low beam is obtained. When the movable reflectors are positioned in a second location, light distribution patterns for high beams are obtained. When the movable reflectors are positioned in a third location, light distribution patterns for daytime running light are obtained. As a result, the vehicle headlamp can achieve downsizing, weight reduction, power saving, and cost reduction. | 08-05-2010 |
20120188783 | VEHICLE HEADLAMP - An AFS-type vehicle headlamp is provided, and includes a bearing holder adapted to hold a bearing that is inserted into an upper support shaft of a lamp unit. The bearing holder is formed integrally with a fixing portion for a bracket, a bearing holding portion adapted to hold the upper support shaft, and a spring portion adapted to compress a tip end of the upper support shaft. The fixing portion includes the bearing holding portion adapted to hold the bearing on a flat plate member in such a manner that a center of the bearing is positioned in a plane that includes the flat plate member. | 07-26-2012 |
20120188784 | VEHICLE HEADLAMP - A vehicle headlamp includes: a lamp unit including an upper support shaft and a lower support shaft that are coaxially formed each other; a bracket adapted to support the lamp unit via a ball bearing in the upper support shaft and via a slider in a lower shaft support portion; an actuator including a mechanism portion adapted to drive the lower support shaft of the lamp unit, the actuator being movable in a forward and backward direction with respect to the bracket; and a spring portion that is fixed to the bracket, and is adapted to compress a tip end of the upper support shaft. | 07-26-2012 |
