Abstract: A light fixture includes a LED assembly and a housing. A lens assembly comprises a lens and a first end cap and a second end cap. The end caps are releasably connected to the housing such that the lens and the end caps are releasably mounted to the housing as a unit. The end caps may be releasably mounted to the housing by a deformable, resilient first engagement member that releasably engages a second engagement when the lens assembly is moved relative to the housing in a first direction. A force is created between the first engagement member and the second engagement member sufficient to hold the lens assembly in the housing and low enough that the lens assembly is removable from the housing by pulling the lens assembly in a second direction opposite to the first direction.

Abstract: A LED lamp includes an at least partially optically transmissive enclosure and a base. A LED assembly comprising at least one LED is located in the enclosure and is operable to emit light when energized through an electrical path from the base. A heat sink comprises a heat dissipating portion that is at least partially exposed to the ambient environment and a heat conducting portion that is thermally coupled to the at least one LED. The heat sink is connected to the base by a snap fit connector comprising a deformable first member on one of the base or heat sink engaging a second member on the other one of the heat sink and the base. A retention member holds the first member in engagement with the second member. A seal is positioned between the heat sink and the base, the seal being compressed between the heat sink and the base.

Abstract: A lamp has an optically transmissive enclosure and a base. A tower extends from the base into the enclosure and supports an LED assembly in the enclosure. The LED assembly comprises a plurality of LEDs operable to emit light when energized through an electrical path from the base. The tower and the LED assembly are arranged such that the plurality of LEDs are disposed about the periphery of the tower in a band and face outwardly toward the enclosure to create a source of the light that appears as a glowing filament. The tower forms part of a heat sink that transmits heat from the LED assembly to the ambient environment. The LED assembly has a three-dimensional shape. An electrical interconnect connects a conductor to the heat sink where the conductor is in the electrical path between the LED assembly and the base.

Abstract: A LED lamp includes an at least partially optically transmissive enclosure and a base connected to the enclosure. A plurality of LEDs are located in the enclosure and are operable to emit light when energized through an electrical path from the base. An optical interface is positioned in the enclosure for electrically isolating a live electrical component and for receiving at least a portion of the light. The optical interface includes a light modifying property for modifying a characteristic of the portion of the light.
