Abstract:
1. A light source comprising: a rod comprising a luminescent material; the rod having a first end opposite a second end, an elongated top surface opposite an elongated bottom surface, and first and second side surfaces disposed between the elongated top surface and the elongated bottom surface; a metal base having a raised spine having a contact surface adapted to contact substantially all of the elongated bottom surface of the rod; a fin having a first fin end, a second fin end, and an edge adapted to contact substantially all of the elongated top surface of the rod; a spring configured and positioned to apply a force to said fin to push the edge against the elongated top surface of the rod whereby the elongated bottom surface of the rod is held in thermal contact with the contact surface of the spine of the metal base; a plurality of light emitting diodes which emit first light of a first color; the plurality of light emitting diodes positioned adjacent the first and second side surfaces of the rod such that the first light of a first color enters the rod through the first and second side surfaces and is absorbed by the luminescent material which in response emits by fluorescence second light of a second color different than the first color which second light is transmitted along said rod to said first end and second end; and wherein the rod is temperature regulated by transmission of heat from the rod to the spine of the metal base.
