<P>PROBLEM TO BE SOLVED: To provide a vehicle lamp capable of electrically switching between a horizontally wide light distribution pattern and a light distribution pattern suitable for AFS (adaptive front-lighting system) projecting light beams leftward and rightward. <P>SOLUTION: The vehicle lamp includes: a projection lens having a light-incident surface and a light exiting surface; and a horizontally long rectangular surface light source composed of a plurality of semiconductor light-emitting devices that are horizontally disposed on both sides of a focus of the projection lens and are independently controlled to be turned on/off. The projection lens vertically converges and horizontally diffuses incident light beams to be emitted. Optical axes of the projection lens and the surface light source are each arranged to be inclined outward by an angle θ with respect to an axis extending in the fore-and-aft direction of a vehicle body so that a light distribution pattern substantially horizontally uniform in a direction horizontal with respect to the vertical axis is formed substantially in front of the vehicle body by light beams emitted from semiconductor light-emitting devices disposed on an outer side with respect to the focus of the projection lens out of the plurality of semiconductor light-emitting devices and passed through the projection lens. <P>COPYRIGHT: (C)2011,JPO&INPIT |
