Patent ID: 8779444

Claim:
An electrically driven L.E.D. lamp assembly ( 20 ) comprising; a substrate ( 22 ) being thermally conductive, a coating ( 24 ) disposed on said substrate ( 22 ) and being electrically insulative for electrically isolating said substrate ( 22 ) and having a low thermal resistance for transferring heat to said substrate ( 22 ), a plurality of light emitting diodes ( 26 ) secured to said coating ( 24 ) with each of said light emitting diodes ( 26 ) having a pair of LED electrical leads ( 32 ), a circuit ( 40 ) being electrically conductive and disposed on said coating ( 24 ) in discrete and electrically conductive spaced lengths ( 42 ) spaced from one another by said coating ( 24 ), a lead coupling agent ( 44 ) disposed about said LED electrical leads ( 32 ) and said circuit ( 40 ) for securing said LED electrical leads ( 32 ) to said circuit ( 40 ) to electrically interconnect said light emitting diodes ( 26 ), said circuit ( 40 ) including a foil tape ( 46 ) electrically interconnecting said light emitting diodes ( 26 ) to one another and having a tape portion ( 48 ) and a coupling portion ( 50 ), said tape portion ( 48 ) comprising a sheet of metal extending continuously along said predetermined lengths ( 42 ) spaced from one another by said coating ( 24 ) and being electrically conductive with said LED electrical leads ( 32 ) to electrically interconnect each of said LED electrical leads ( 32 ) to an LED electrical lead ( 32 ) of an adjacent light emitting diode ( 26 ), and said coupling portion ( 50 ) disposed axially along said tape portion ( 48 ) between said tape portion ( 48 ) and said coating ( 24 ) to secure said tape portion ( 48 ) to said coating ( 24 ) whereby electricity driving said light emitting diodes ( 26 ) is conducted through said tape portion ( 48 ) between each of said interconnected light emitting diodes ( 26 ) and heat generated by said light emitting diodes ( 26 ) is transferred from said light emitting diodes ( 26 ) through said coating ( 24 ) to said substrate ( 22 ) for dissipating the heat.
