Vehicular lamp system
First Claim
1. A vehicular lamp system comprising:
- shading means for partially shading light emitted from a lamp to vary a light distribution pattern;
shaded region changeover means for changing a shaded region using the shading means; and
deflection control means for controlling deflection of a lamp optical axis in a lateral direction, whereinthe shaded region changeover means is operable to change between a shaded state where a high light intensity region of an illumination region of the lamp is shaded and an unshaded state where a high light intensity region is not shaded, and the deflection control means is operable to laterally deflect the lamp optical axis in accordance with the shaded or unshaded state of the high light intensity region due to the shaded region changeover means.

Abstract
The light distribution of a vehicle headlamp can be changed between various modes, including a basic mode and a motorway mode. In the basic mode, shaded region changeover means block a high light intensity region, and deflection control means controls a lamp optical axis Lx to a straight travel direction. In the motorway mode, the shaded region changeover means does not block the high light intensity region, and the deflection control means controls deflection of the lamp optical axis to a host vehicle lane side. A light distribution in which the high light intensity region faces a far distance ahead of the host vehicle lane can be obtained, and the host vehicle lane is brightly illuminated without dazzling a driver of a preceding vehicle or an oncoming vehicle. Accordingly, illumination suited to the motorway mode during high speed and medium speed travel can be achieved.

7. A vehicular lamp system comprising:
-
a shade operable to partially shade light emitted from a lamp to vary a light distribution pattern; a rotational shade device operable to change a shaded region using the shade; and a deflection control device operable to control deflection of a lamp optical axis in a lateral direction, wherein the shade is further operable to change between a shaded state where a high light intensity region of an illumination region of the lamp is shaded and an unshaded state where a high light intensity region of an illumination region is not shaded, and the deflection control device is further operable to laterally deflect the lamp optical axis in accordance with the shaded or unshaded state of the high light intensity region. - View Dependent Claims (8)
