Abstract
A lamp including a reflector and a light source for illuminating a target area in which the light rays on the target and have a small average local divergence. The reflector and light source are configured so that the predominant portion of the light rays which strike the target area do not cross the axis of the reflector. The reflector may be segmented and the light source is located so that various points on the target receive radiation which is reflected from a different number of segments with points near the periphery of the target area receiving radiation from a greater number of segments than those near the center of the target.
