20090231866 | VEHICLE HEADLAMP APPARATUS - A vehicle headlamp apparatus is provided. The vehicle headlamp apparatus includes a lamp unit, a first additional lamp unit which forms a first light distribution pattern, a second additional lamp unit which forms a second light distribution pattern overlapping with the first light distribution pattern, and a controller. The first light distribution pattern includes at least one first partial region, and the first additional lamp unit adjusts a luminous intensity of a light to be irradiated toward the first partial region. The second light distribution pattern includes at least one second partial region which partially overlaps with the first partial region, and the second additional lamp unit adjusts a luminous intensity of a light to be irradiated toward the second partial region. The controller controls the first additional lamp unit and the second additional lamp unit to adjust the luminous intensity of the partial regions. | 09-17-2009 |
20090231873 | VEHICLE HEADLAMP APPARATUS - A vehicle headlamp apparatus is provided. The vehicle headlamp apparatus includes a low beam lamp unit which forms a low beam distribution pattern having a cutoff line along an upper edge thereof, and an additional lamp unit which forms an additional light distribution pattern including an area above the cutoff line of the low beam distribution pattern. The additional lamp unit is configured such that a luminous intensity of at least a portion of the additional light distribution pattern increases toward a horizontal line from above. | 09-17-2009 |
20130314936 | VEHICULAR HEADLAMP - A vehicular headlamp includes: a plurality of semiconductor light emitting element chips; and a reflector that has a reflection surface with a paraboloid shape, and that reflects, by the reflection surface, light from the semiconductor light emitting element chips so as to send the light in a headlamp beam direction of the vehicular headlamp, wherein the plurality of semiconductor light emitting element chips are arranged along a plane perpendicular to the headlamp beam direction, and a focal point of the reflection surface of the reflector is disposed in or near an area between the semiconductor light emitting element chips that are next to each other. | 11-28-2013 |
20140042325 | OBSTACLE DETECTING DEVICE - An obstacle detecting device includes: a light source having both LED units each for emitting visible light and an infrared light unit for emitting infrared light; and a rotating reflector configured to be rotated in one direction around a rotational shaft while reflecting the visible light and the infrared light emitted from the light source. The rotating reflector is configured, by its rotating movement: to emit the visible light from each of the LED units as an irradiation beam such that a first light distribution pattern is formed by scanning with the irradiation beam; and to emit the infrared light from the infrared light unit as an irradiation beam such that a second light distribution pattern is formed by scanning with the irradiation beam. | 02-13-2014 |
20140043805 | OPTICAL UNIT - An optical unit includes: a light source having both a first light emitting element for emitting light having a first color and a second light emitting element for emitting light having a second color that is different from the first color; and a rotating reflector configured to be rotated in one direction around a rotational shaft, while reflecting the light having the first color and the light having the second color, which have been emitted from the light source. In the rotating reflector, a reflecting surface is provided such that a predetermined light distribution pattern is formed with the light having the first color and the light having the second color, which have been reflected by the rotation of the rotating reflector, being superimposed one on another. | 02-13-2014 |
20140092618 | OPTICAL UNIT - An optical unit includes a lens through which light emitted from a light source enters from behind and the light emits frontward as an irradiation beam. A rotation lens moves periodically, and a front part is scanned with the irradiation beam, so that a predetermined irradiated region can be formed. The rotation lens may be configured such that the lens rotates about a rotation axis connected to a drive part and such that the direction of light, which emits from the light source and is then refracted when the light passes through the lens, varies periodically. | 04-03-2014 |
20150092435 | VEHICLE HEADLAMP - A vehicle headlamp includes a light source, a projection optical member, a light deflector, and a tube shaped housing. The projection optical member projects light, which is incident on the projection optical member, ahead. The light deflector includes a plurality of optical devices that are arrayed. The optical devices are individually switchable between a first state and a second state. In the first state, the optical devices reflect light emitted from the light source to a direction other than a direction towards the projection optical member. In the second state, the optical devices reflect the emitted light towards the projection optical member. The light deflector is disposed inside the housing. The projection optical member is disposed in an opening portion of the housing. A first portion, of the housing, intersecting a path of a light beam incident on the light deflector is transparent. | 04-02-2015 |
20150191115 | VEHICLE LAMP AND METHOD FOR CONTROLLING THE SAME - A vehicle lamp that can form a light distribution pattern required therefor effectively even with the existing DMD is provided. A vehicle lamp | 07-09-2015 |
