Abstract
A portable personal headlamp utilizes an array of light-emitting diodes on the front face of a circuit board. Arc-shaped projections on the front face of a finned heat sink are in heat-conducting relationship with printed conductors on the rear face of the circuit board, which partially surround one lead of each light-emitting diode.
Claims7
A portable light comprising:
- a housing composed of a synthetic resin;
- a printed circuit board mounted within the housing, said printed circuit board having a front face and an opposite back face;
- a plurality of light-emitting diodes mounted on said printed circuit board and disposed on said front face of the printed circuit board, each said light-emitting diode having a lead which extends through the printed circuit board and is connected to a printed conductor on said back face of the printed circuit board;
- a metal heat sink having a front side and a back side, said heat sink having a plurality of projections on the front side thereof, each said projection being associated with a different one of said light-emitting diodes, and each said projection being in heat-conducting relationship with the printed conductor to which the lead of its associated light-emitting diode is connected;
- and
- a set of heat-dissipating fins on said back side of the metal heat sink.
