Abstract
A lighting apparatus is provided with a swivel device, a leveling device, a distribution light changeover device for switching the light distribution between a main-beam and a sub-beam, and a controller coupled to the devices via signal transmission paths. The controller controls the devices in accordance with a traveling condition of a vehicle. When an abnormality of the swivel device, the leveling device or the signal transmission paths is detected, the controller forcedly switches the light distribution to the sub-beam. The light distribution is also switched to the sub-beam when the swivel device or the leveling device stops at the dazzling position, thereby preventing the dazzling.
Claims12
A vehicle lighting apparatus comprising:
- a swivel device for changing an irradiation direction of a lamp in a horizontal direction;
- a leveling device for changing the irradiation direction in a vertical direction;
- a distribution light changeover device for switching a distribution of a light of the lamp between a main-beam and a sub-beam;
- and
- a controller coupled to the swivel device, the leveling device and the distribution light changeover device via signal transmission devices, and controls the swivel device, the leveling device and the distribution light changeover device in accordance with a traveling condition of the vehicle,
- wherein the controller is capable of detecting an abnormality of each of the swivel device, the leveling device and the signal transmission devices, and
- when the abnormality of one of the devices is detected, the controller switches the distribution of the light to the sub-beam by actuating the distribution light changeover device.
