Abstract
An LED lamp has dual modes of operation from fluorescent lamp fixtures. A first circuit powers at least one LED in a first mode of operation when first and second power connector pins at a first end of the lamp are inserted into power receptacles of the fixture that are directly connected to power mains. A second circuit powers at least one LED in a second mode of operation when the second power connector pin at the first end of the lamp and a third power connector pin at a second end of the lamp are inserted into power receptacles of a fixture powered from an electronic ballast. First and second conduction control means permit the second circuit to power at least one LED during the second mode of operation.
