Patent ID: 7625103

Claim:
A light emitting apparatus comprising: a mounting substrate that includes a peripheral portion and a central portion; a plurality of solid state light emitting elements on the mounting substrate; a housing that provides a first thermal conduction path for at least some heat generated by the solid state light emitting elements; by being in contact with the peripheral portion of the mounting substrate a first thermal conduction apparatus that provides a second thermal conduction path that is different than the first thermal conduction path to the housing for at least some heat generated by the solid state light emitting elements; by being in contact with the central portion of the mounting substrate and a second thermal conduction apparatus that provides a third thermal conduction path to the housing that is different than the first and second thermal conduction paths for at least some heat generated by the solid state light emitting elements by being in contact with an intermediate portion of the mounting substrate that is between the central portion and the peripheral portion.
