Abstract: A LED lamp for use in an existing light fixture having an electrical receptacle comprises an at least partially optically transmissive enclosure and a base having an external size that may be the same size or smaller than an external size of the electrical receptacle. A LED assembly is operable to emit light when energized through an electrical path from the base. The base comprises a universal mounting mechanism for mounting the lamp to the light fixture. A surge protector and an electrical connector are positioned at least partially in the base and are in the electrical path. A heat sink comprises a first portion in the enclosure for supporting the LED assembly and a second portion external of the enclosure for dissipating heat. The base is connected to the heat sink.

Abstract: A tube that is at least partially optically transmissive. An LED mounted on a substrate is positioned in the tube and is operable to emit light through the tube when energized through an electrical path. Pins are in the electrical path. An electrical conductor electrically couples the pins to the electrical path, the electrical conductor is biased into engagement with an electrical contact on the substrate. The substrate may be secured to the tube by an adhesive. The substrate may be secured to the end caps and be suspended in the tube.

Abstract: An LED light fixture includes a heat sink structure, at least one LED board in thermal engagement with the heat sink structure, the at least one LED board having at least one LED emitter thereon, and an on-board connector on the LED board for connecting electrical wiring to the LED emitter(s). At least one enclosing member forms with the heat sink an interior space enclosing a corresponding LED board, the rigid enclosing member defining a wiring aperture therethrough in alignment with the on-board connector. The LED light fixture also has an exterior wireway structure including a one-piece duct which has an end portion engaged with the wiring aperture and forms a channel for wires to the on-board connector. The wireway structure further includes a single-piece rigid cover secured with respect to the enclosing member and enclosing the duct.
