摘要： Lamp units for radiating a beam ahead of a vehicle in a light distribution pattern are housed in a lamp body. Illumination of the auxiliary lamp units is controlled based on driving conditions. Illumination control means extinguish light through dimming by gradually decreasing voltage applied to the light sources. When the applied voltage has dropped to a threshold value, the applied voltage is controlled to zero immediately. Compared to when the lamps remaining in an illuminated state are suddenly extinguished, a change in, quantity of light is mild, and no uncertainty arises. Below a threshold value where the applied voltage gradually drops to the threshold value and a change may arise in the filament crystalline structure due to annealing at a transition temperature, the applied voltage approaches zero. Hence, the filament does not pass from the transition temperature while being rapidly cooled, thus avoiding filament crystalline structure change.

摘要： A vehicle headlamp includes a lamp body having a hollow portion opening forward, a support member supported tiltably in the lamp body, and a plurality of reflectors supported side by side in one of the vertical and lateral directions by the support member. Each reflector is made to support a corresponding light source and least one of the reflectors is pivotably supported by the support member in the horizontal direction. In one embodiment, a lower reflector is pivotable in the horizontal direction and a low beam is formed by an upper reflector and the light source supported by the upper reflector. In this embodiment, the upper reflector does not have any portion that does not affect luminous distribution.

摘要： The lighting directions of a plurality of lamps RL and LL are controlled independently or integrally corresponding to a running condition. When a vehicle changes a running direction, the direction of the optical axis of one of the lamps is deflected earlier in the running direction and the direction of the optical axis of the other lamp is maintained in a straight running direction in a running condition in which other cars or obstacles might be present in the straight running direction of the vehicle, and the direction of the optical axis of the other lamp is deflected with a delay upon receipt of a further steering operation. It is possible to carry out an illumination in the running direction and the straight running direction of the vehicle. In particular, the invention is very effective for maintaining the safety running of the vehicle on an intersection road or at time of a lane change.

摘要： A vehicle light apparatus which serves to change a lighting range of a lamp L for illuminating a forward part of the vehicle corresponding to a steering angle of the vehicle comprises lighting range control means for turning the lighting range into an opposite direction to a current steering direction when steering is returned into a straight running direction. When a steering angular velocity is greater than a predetermined value, a lighting range for illuminating an opposite side is increased following the return of the steering into the straight running direction. A next curve or the course of an intersection road can be illuminated prior to the steering operation in a running condition on an S-shaped road or an intersection road in which right and left turns continue. Thus, the vehicle light apparatus is very effective for maintaining the safe running of the vehicle on a curved road and an intersection road.

摘要： A vehicle light apparatus comprises a controller 10 for changing a lighting range of a lamp L for illuminating a forward part of a vehicle corresponding to a steering angle of the vehicle and for controlling the lighting range of lighting means corresponding to a steering angular velocity of the vehicle. Alternatively, there is provided lighting range control means for changing a lighting range of lighting means for illuminating a forward part of the vehicle corresponding to a steering angle of the vehicle and for controlling the lighting range of the lighting means based on an operation of a turn signal lamp of the vehicle. It is possible to decide a running condition of the vehicle from the steering angular velocity or the operation state of the turning signal lamp and a vehicle speed, thereby rapidly controlling a change in the lighting direction or the lighting area of the lamp L in a running direction. Consequently, it is possible to carry out an illumination in the running direction prior to a steering operation. Thus, it is effective for maintaining the safe running of the vehicle on a curved road and an intersection road.
