Abstract
A portable battery powered high intensity lighting system that produces solar quality illumination at four to six times the efficiency of comparable incandescent lighting systems includes a light head and a power source. The light head contains an HID (high intensity discharge) arc lamp. A sealed enclosure containing a ballast is attached immediately adjacent to the lamp assembly. The ballast enclosure is preferably potted with a thermally conductive epoxy.
Claims15
A high intensity discharge lamp assembly, comprising:
- a) an hermetically sealed glass envelope containing a mixture of ionizable elements and/or compounds;
- b) a sealed ballast container mounted adjacent to said glass envelope;
- c) an electronic ballast contained in said container, said ballast having an input and an output;
- d) an anode disposed in said envelope and electrically coupled to one pole of said ballast output;
- e) a cathode disposed in said envelope and electrically coupled to another pole of said ballast output;
- and
- f) coupling means for coupling said input of said ballast to a DC power source.
