Abstract: A light source and method for making the same are disclosed. The light source includes a plurality of Segmented LEDs connected in parallel to a power bus and a controller. The power bus accepts a variable number of Segmented LEDs. The controller receives AC power and provides a power signal on the power bus. Each Segmented LED is characterized by a driving voltage that is greater than 3 times the driving voltage of a conventional LED fabricated in the same material system as the Segmented LED. The number of Segmented LEDs in the light source is chosen to compensate for variations in the light output of individual Segmented LEDs introduced by the manufacturing process. In another aspect of the invention, the number of Segmented LEDs connected to the power bus can be altered after the light source is assembled.

Abstract: A light source that is adapted to replace existing fluorescent tubes in an existing fluorescent light fixture is disclosed. The light source includes a plurality of LEDs mounted on a heat-dissipating structure, first and second plug adapters that mate with the florescent tube connectors of the fluorescent tube the light source is to replace, and a power adapter that converts power from a fluorescent tube ballast presented on the first and second plug adapters to DC power that powers the LEDs. The light source is powered from the output of the existing fluorescent ballast. The light source can utilize the existing metallic enclosure as a heat-radiating surface and/or direct air heat transfer from the surface of the heat-dissipating structure.
