ABSTRACT:
A focusing arrangement has a lens disposed adjacent a lamp, a sensor for detecting a parameter which varies with a focal position of light focused by the lens, and a controller for adjusting the position of the lens based upon an output from the sensor in a manner which modifies the focal position of the light by the lens and maximizes the parameter detected by the sensor.
