Abstract:
1. A portable light heat dissipater comprising: a heat sink having a cylindrical wall wherein a portion of the cylindrical wall defines a base, the base having first and second opposing sides, the first side being on the exterior of the cylindrical wall for having a light source thermally coupled thereto, and the second side of the base and the interior of the cylindrical wall having a plurality of walls extending inwardly therefrom interior the cylindrical wall for defining a plurality of interior axial fluid passages therethrough; an elongated hollow tubular member defining a fluid passage therethrough; a pivotable joint supporting said heat sink at a first end of the elongated hollow tubular member, whereby said heat sink is pivotable to different orientations relative to said elongated hollow tubular member; a flexible sheath between the first end of said elongated hollow tubular member and said heat sink for defining a fluid passage between the fluid passage of said elongated hollow tubular member and the plurality of interior axial fluid passages of said heat sink; a fluid mover disposed in the fluid passage of said elongated hollow tubular member near an end thereof remote from said heat sink for selectively causing a fluid to move through the fluid passages of said elongated hollow tubular member and said flexible sheath and through the plurality of interior axial fluid passages defined by the walls of said heat sink; and a light source disposed adjacent to and thermally coupled to the first side of the base of said heat sink, whereby said light source is cooled by fluid moved by said fluid mover through the fluid passage defined by said elongated hollow tubular member, the fluid passage defined by said flexible sheath and the interior axial fluid passages defined by said heat sink.
