    Abstract: A troffer light fixture has a housing with a LED assembly positioned in the housing. The LED assembly includes at least one LED array comprising LEDs of at least two different colors. The LED assembly includes a first LED array having a first LED on a first string and a second LED on a second string and a second LED array having a third LED on a third string and fourth LED on a fourth string. A wide lens covers the LED array. A reflector assembly has a first reflective surface and a second reflective surface reflecting light from the at least one LED array laterally across the width of the wide lens. Alternatively, the LED array may be approximately one-half the width of the wide lens and the reflector may be eliminated.

    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 lamp includes an enclosure that is at least partially optically transmissive and a base. One or more LEDs are located in the enclosure and are operable to emit light when energized through an electrical path from the base. A heat sink having 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 transfers heat from the LEDs to the ambient environment. The heat sink includes fins that are located in the enclosure. A housing is press fit between the heat dissipating portion and the heat conducting portion and forms part of the heat sink. The housing is thermally coupled to the heat sink and is made of thermally conductive material and is at least partially exposed to the ambient environment. The housing defines at least a portion of the enclosure.

    Abstract: A light fixture includes a LED assembly and a housing. A first end cap is permanently connected to the troffer. A lens assembly comprises a lens covering the LED assembly and a second end cap, the lens having a first end connected to the second end cap and a second end releasably connected to the first end cap. The second end cap is releasably connected to the housing such that the lens and the second end cap are releasably mounted to the housing as a unit. The lens has a first longitudinal edge and a second longitudinal edge where a first magnetic strip is attached to the first longitudinal edge and a second magnetic strip is attached to the second longitudinal edge. The first and second magnetic strips are magnetically adhered to the housing.

    Abstract: The LED lamp has an enclosure defined by a housing and an optically transmissive exit surface. A base is connected to the enclosure. The housing is connected to the base at a proximal end and diverges as the housing extends away from the base to a distal end. The optically transmissive exit surface is connected to the distal end of the housing. A LED board is positioned transversely to a longitudinal axis of the enclosure adjacent the distal end to define a first interior space and a second interior space. A passage communicates the first interior space with the second interior space. A first aperture and a second aperture in the enclosure communicate the first interior space and the second interior space with the exterior of the lamp.
