Patent ID: 7637629

Claim:
A xenon short-arc lamp system, comprising: a first and a second short-arc lamp anode heatsink ( 106 , 104 ) having substantially different heat capacities from one another, and both having similar outside form factors and made of extruded finned aluminum, wherein, the first heatsink ( 106 ) includes a split ( 107 ) and a clamp ( 110 ) to close a gap in the split for securing it to a lamp ( 102 ) screwed with a matching base stud ( 112 ) into a base adapter ( 108 ) for cooling, and the second heatsink ( 104 ) includes a single, coaxial, female threaded machine screw hole ( 105 ) to directly accept and secure it to lamp ( 102 ) with matching base stud ( 112 ) for cooling, wherein the tighter and more intimate connection of said lamp ( 102 ) and its base stud ( 112 ) to the second heatsink ( 104 ) has a significantly better heat transfer characteristic than that of the first heatsink ( 106 ); and a base adapter ( 108 ) providing for said lamp ( 102 ) to be accommodated by the first heatsink ( 106 ) by accepting its base stud ( 112 ) directly in a screw hole ( 114 ), and for presenting a cylindrical lamp base format of a conventional xenon short-arc lamp with standardized cylindrical dimensions to the first heatsink ( 106 ) for clamping; wherein, said lamp ( 102 ) and base adapter ( 108 ) when screwed together approximate said cylindrical lamp base format of said conventional xenon short-arc lamp and can functionally replace it, and said lamp ( 102 ) and base stud ( 112 ) can be screwed directly into the second heatsink ( 104 ) and operated at a substantially higher power than heatsink ( 106 ).
