The vehicle cornering lamp includes three reflector units 12A, 12B, and 12C, whose light emitting directions are respectively set to angles of 30°, 45°, and 60°, with respect to the traveling direction of the vehicle. The vehicle cornering lamp also includes a control unit 20 for controlling light emission--from the reflector units 12A, 12B, and 12C--according to the travel conditions of the vehicle. When the vehicle turns to the left at an intersection, a traveling road onto which the vehicle will turn left, and a road shoulder, are sufficiently irradiated by switching on the reflector units 12A, 12B and 12C in the order of 12A→12B→12C→12B→12A, so that pedestrians can quickly be detected. | InventorsAssigneeApplicationNo. 09/901564 filed on 07/11/2001US Classes:362/464, Condition responsive (e.g., position)362/465, Automatically adjusted headlamp beam362/466Computer controlledField of Search362/543, Plural light sources362/544, With common housing362/545, Including light emitting diode362/247, Reflector type modifier362/241, Reflector type modifiers362/465, Automatically adjusted headlamp beam362/466, Computer controlled362/240Units have common housingExaminersPrimary: Husar, Stephen F.Assistant: Lee, Guiyoung Attorney, Agent or FirmUS Patent References4225906, Luminaire apparatus with multiple light sources and methods of operating sameIssued on: 09/30/1980 Inventor: Gulliksen , et al.5404278, Vehicular cornering lamp system Issued on: 04/04/1995 Inventor: Shibata, et al.5455747, Vehicle lighting device Issued on: 10/03/1995 Inventor: Aoyama5941633, Headlight for motor vehicle Issued on: 08/24/1999 Inventor: Saito, et al.6024474, Vehicle lamp having a plurality of lamp units with a unified lens assembly with joining legs Issued on: 02/15/2000 Inventor: Tanaka6270241, Unit comprising at least one headlight and at least one indicator light, for a motor vehicle Issued on: 08/07/2001 Inventor: Collot, et al.6505962Vehicle lamp Issued on: 01/14/2003 Inventor: Gotou International ClassesB60Q 1/12 (20060101)B60Q 1/04 (20060101) Foreign Application Priority Data2000-07-11 JP |
