Abstract

A rapidly cooled LED comprises many semiconductor areas (31) on a substrate (32) connected to an electrode (33) and sealed into a thermally conductive cover (50) containing a cooling fluid dielectric (37). Operational heat is dissipated through the leads, the conductive cover and cooling fins on the substrate.
