Luminaire having an improved thermal management arrangement

A lighting fixture comprising:

• a fixture support member;
• a high intensity light source connected to said support member;
• means for energizing said light source, said energizing means being connected to said support member;
• reflector member connected to said support member and being disposed at least partially around said light source so as to direct the light output of said light source in a predetermined pattern, said reflector member having at least one opening formed therein;
• a sleeve member connected to said support member and being disposed in at least a partially surrounding manner to said light source and at a position between said reflector member and said light source;
• wherein said sleeve member is constructed of a light transmissive material and has an opening formed at the upper end thereof, said sleeve member being effective such that a portion of the heat generated by said light source can be channeled through said sleeve member opening and away from said reflector member thereby;
• and,
• wherein said opening of said sleeve member is smaller in size relative to said at least one reflector opening, said sleeve member opening and said reflector member opening being disposed relative to one another such that a space exists therebetween, said space being effective such that an air flow can occur between said reflector member and said sleeve member, such air flow travelling through said space.
