Portable light |
摘要 |
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.
