Abstract
A vehicular head lamp enables rotation of an upper reflector ( ) relative to an intermediate reflector ( ), thereby changing a dispersed light-distribution pattern (WP) with respect to a fixed reference light-distribution pattern (LP and HP). By causing a lower reflector ( ) to rotate relative to the intermediate reflector ( ), a collimated light-distribution pattern (SP) is changed with respect to the reference light-distribution patterns (LP and HP). The result of this arrangement is an improvement in visibility when the vehicle negotiates a curve.
