Abstract
A solid-state LED lighting lamp (SSL-LED lamp), based on AC or DC-emitters, which runs under a high AC or DC voltage, with high light generation capability, high reliability and long lifespan, is disclosed. A plurality of AC or DC-emitter chips are integrated on a thermally conductive submount and the electrically conductive element pathways on the submount provide electrical interconnections between the mounted chips and also between the individual LEDs on each chip. The conducting elements also provide redundant current paths at the AC or DC-emitter chip level and individual LED level. Depending on the detail design, the LED SSL-lamp may be directly powered by an AC voltage (i.e. 110/120V or 220/240V power grid) or a high DC voltage. With this design, the LED SSL-lamp can provide sufficient illumination to replace the incandescent or florescent light bulbs for general lighting purpose. The distributed emitter array design ensures the heat dissipation. The redundant current path design ensures the long lifespan and high reliability.
