The ends each have metal electrical contact rings, one for the anode and one for the cathode. The body has two different diameters with a step in between at the middle that is formed into the ceramic. A standardized anode heat sink for lesser-powered conventional one inch modular lamp bases is fitted to the base and makes thermal contact to the ledge underside of the step in the ceramic. Thus two dissimilar orthogonal heat transfer interfaces are formed, one radial which is metal to metal, and one axial which is ceramic to metal. A standardized cathode heat sink for the same lesser-powered conventional one inch modular lamp bases is relieved for about half of its inside length to accommodate the 1.4 inch reflector diameter and is fitted to the front.Field of SearchHaving heat conducting pathFor electrode within an envelope WITH OPTICAL DEVICE OR SPECIAL RAY TRANSMISSIVE ENVELOPE Plural diverse optical devices Reflector Electrode forms part of envelope Greater than 760 torr Envelope with particular structure Coated or laminated Having particular electrode structure Cathode or anode Using liquids or fluid flow directing means With cooling means With air circulating means Thermal conduction Through support means | |
