| 1. A forced air cooling unit for a light source, said unit comprising
a longitudinal housing having opposite side walls and a longitudinal centerline;
a heat sink suspended between said walls parallel to said centerline, said heat sink having a first face and a second, opposite,
face, and
a base suspended between said side walls opposite said second face so as to define therewith an internal chamber, said base
including a plurality of similar sections positioned end to end parallel to said centerline, each section having a first portion
extending substantially perpendicular to said second face and dividing the internal chamber length wise into separate compartments
and a second portion extending substantially parallel to said second face, a cooling fan mounted to the second portion of
each section proximate to the first portion thereof and a vent opening in the second portion of each section distal to the
first portion thereof so that each fan circulates air only within the corresponding compartment.
