Patent ID: 7740380

Claim:
A high intensity solid state lighting apparatus comprising: an elongated axial thermal transfer member having first and second opposed ends and a longitudinal axis, said member being formed of a solid material having a thermal conductivity along said axis that is substantially greater than its thermal conductivity in a first plane transverse to said axis, having a thermal conductivity in a second plane transverse to the first plane that is substantially the same as its thermal conductivity along said axis, and being formed of a highly oriented pyrolytic graphite material comprised of a plurality of generally parallel graphene layers that are generally parallel to the second plane of said axial thermal transfer member; at least one light emitting diode (LED) mounted at said first end of said axial thermal transfer member so that heat generated by said LED is conducted along said axis toward the second end of said axial thermal transfer member, and an optic element mounted relative to said LED for receiving light emitted by said LED and distributing said light into a desired angle of illumination.
