Abstract
A light source is provided that includes a reflector for generating a substantially rectangular beam. The light source may include an arc lamp that includes a magnetic field generation means in the vicinity of the arc for reducing the arc diameter, or a secondary reflection means for avoiding part of the light that is generated from being obscured by the arc lamp electrodes.
