ABSTRACT:
A lamp assembly includes improved thermal management properties provided by a thermal shield received about the neck region of a reflector. This reduces the temperature in the seal region of the light source. Additionally, the thermal shield can be incorporated into a modular housing to provide a contained lamp assembly. The module includes cooling fins that effectively reduce the temperature of the module without adversely effecting the light output. Alternatively, the housing is operatively connected to an external, secondary heat sink.
