Abstract
The present invention is directed to a lighting fixture thermal insulating system which incorporates the spaceage technology of layered metallized polymer insulation. The present invention utilizes a structure and combination which yields an insulation system of superior performance while being cost competitive and because of reduced space requirement creates greater freedom of design in the manufacture of lighting fixtures. The laminations of metallized polymer and a spacer material may be located above or below the mounting pan or both.
