Abstract:
An electrically driven light-emitting-diode (LED) lamp assembly comprising;an electrically insulating circuit board (12) having opposed first and second surfaces (14 and 16), electrically conductive circuit traces (18) on said first surface (14) of said circuit board (12), a plurality of LEDs (20, 22 or 24) each having a pair of electrical leads (26) in electrical engagement with said traces (18), each of said LEDs (20, 22 or 24) including a heat sink (28), a heat dissipater (30) disposed in parallel relationship to said circuit board (12), said assembly characterized by said circuit board (12) presenting a hole (32) therethrough and around each LED (20, 22 or 24), and said heat sink (28) of each LED (20, 22 or 24) being disposed in thermal contact with said heat dissipater (30) for conveying heat from said LEDs (20, 22 or 24) to said heat dissipater (30).
