Dual AC-LED/DC-LED Lamp With Alternating Power Sources

摘要

A lighting device includes two different types of light emitting elements and two different types of power sources for selective illumination. In particular, the lighting device has AC-LEDs and DC-LEDs that are illuminated by an AC power source and a DC power source, respectively, without the need for current conversion. The AC-LEDs and DC-LEDs may be disposed within a LED lamp which is installable in any preexisting light fixture.
