  • Patent number: 10895357
    Abstract: A vehicle lamp forms an additional high-beam light distribution pattern with light emitted though a projection lens from a plurality of light emitting elements. The plurality of light emitting elements are disposed to be aligned in a transverse direction below a rear focal point of the projection lens and can be lit individually. The vehicle lamp forms an additional light distribution pattern by lighting the plurality of light emitting elements at the same time to form a high-beam light distribution pattern. In addition, the vehicle lamp forms another additional light distribution pattern where a part of the additional light distribution pattern is omitted by selectively lighting a part of the plurality of light emitting elements so as to form an intermediate light distribution pattern.

  • Patent number: 10704753
    Abstract: An auxiliary lamp for a vehicle. Ordinary headlamps are restricted by law in the intensity that they direct towards oncoming drivers. This can cause inconveniently low illumination to a side of the vehicle, such as along a line 20 or 25 degrees left of center for a left-hand driver side vehicle. An auxiliary headlamp assembly is added to provide an auxiliary beam that supplements the primary beam. The auxiliary beam increases illumination along this line, yet maintains total illumination toward oncoming drivers below allowed limits.

  • Patent number: 9316374
    Abstract: A vehicle headlight utilizes a rotationally asymmetric projection lens with its light emitting surface inclined with respect to the optical axis thereof, whereby the light emitted from the light source and projected forward through the light emitting surface of the projection lens is diffused substantially uniformly with respect to the optical axis of the projection lens, for example, uniform substantially in the right and left directions and/or the upper and lower directions. This can be achieved by designing the reflecting surface to have its optical axis inclined with respect to the optical axis of the projection lens by a predetermined angle so that light emitted from the light source and projected forward through the light emitting surface of the projection lens is made uniform with respect to the optical axis of the projection lens (for example, uniform substantially in the right and left directions and/or the upper and lower directions).

  • Patent number: 9227553
    Abstract: Method and device for adjusting lighting for a vehicle in consideration of the visibility of a curve, light having a glare effect (high beam light) being deactivated before negotiating a curve, if the curve is not visible, or optionally the illumination being increased if the curve is visible. Adjusting the lighting, in particular of headlights, for a vehicle having a first step, in which an upcoming curve is recognized, its visibility is ascertained, the visibility representing the possibility of glare, in particular to other road users, in particular to oncoming traffic, and a second step, of adjusting the lighting between the least possible glare and the best possible illumination, characterized in that the adjustment is carried out as a function of the visibility.

  • Patent number: 9108566
    Abstract: A vehicle headlamp system includes a headlamp assembly having a light source and a beam pattern panel. The beam pattern panel includes one or more regions capable of changing between opaque and transparent light-transmission states to selectively allow light from the light source to pass through the panel. The panel may be an LCD panel with a plurality of liquid crystal elements arranged in an array with the ability to provide a plurality of different beam patterns. The beam pattern may be determined and changed in real time based on information received at a system processor about one or more vehicle and/or road conditions. The headlamp system can direct a projected light beam into a curve in the road ahead and/or automatically change the direction of the projected beam to avoid shining light directly at oncoming drivers.
