Abstract:
1. A lamp assembly adapted for use with a vehicle that includes a steering linkage system, said lamp assembly comprising: a base; a lamp unit; a driving device mounted to said base, and including a transmission axle that is coupled to said lamp unit, and a drive unit for driving said transmission axle to rotate in opposite first and second directions relative to said base such that said lamp unit is movable to a selected one of a default position, where said lamp unit has an illuminating direction parallel to a vehicle axis, and left and right limit positions, where the illuminating direction of said lamp unit forms left and right limit angles with the vehicle axis, respectively; a detecting device including a detected component provided on said transmission axle, and a default sensing component provided on said base and cooperating with said detected component so as to generate a default position signal when said lamp unit is at the default position; and a control device coupled to said driving device and said detecting device, said control device being adapted to be coupled to the steering linkage system and being further operable in response to user manipulation of the steering linkage system so as to control said driving device to move said lamp unit according to angular displacement of the steering linkage system, wherein said control device is operable so as to control said driving device to restore said lamp unit to the default position under a predetermined condition with reference to the default position signal regardless of the angular displacement of the steering linkage system.
