Abstract: A retrofit light fixture for retrofitting an existing strip-style light fixture includes a housing, a light emitting diode, a driver, and a bracket. The housing includes a top portion, a side portion, and an end cap, and the housing defines an interior space. At least one of the top portion and the side portion define an elongated opening. The bracket includes a locking flange configured to selectively engage with a portion of a housing of the existing strip-style light fixture. The bracket is slidably coupled to the housing with a fastener that extends through the elongated opening. The bracket is selectively repositionable between a disengaged orientation and an engaged orientation, and the bracket is configured to interface with a portion of the existing strip-style light fixture and thereby secure the retrofit light fixture in place when selectively repositioned into the disengaged orientation.

Abstract: A light fixture includes a housing with a channel configured to contain a driver for driving one or more light emitting diodes located outside the channel. The housing includes slots configured to receive and secure a lens. The light fixture further includes a removable channel cover, tabs located along the length of the channel and adjacent to the channel on the housing, and a lens bar having a first flange configured to secure the lens and a second flange configured to be inserted underneath the tabs. The lens bar is secured in place with the second flange underneath the tabs by the channel cover which prevents the lens bar from moving laterally with respect to the tabs. The slots, the first flange, and a flange running the length of the light fixture perpendicular to the slots are configured to cover the edges of the lens when installed.

Abstract: A retrofitting kit for retrofitting an existing troffer light fixture having a troffer housing includes a door assembly and a retainer. The door assembly includes a housing and a light source within the housing. The retainer is fixed to the housing of the door assembly and configured to engage at least one of the troffer housing and a T-bar of a ceiling system to thereby selectively secure the door assembly within the ceiling system. The retainer is positioned such that the engagement between the retainer and the at least one of the troffer housing and the T-bar of the ceiling system is direct.

Abstract: A retrofitting kit includes at least one of an adapter bracket and a retainer configured to engage at least one of an existing troffer light fixture and a T-bar of a ceiling system and a door assembly configured to be held in the ceiling system by the at least one of the adapter bracket and the retainer. The door assembly includes a lens, a housing configured to hold the lens, the housing including one or more sidewalls disposed around a periphery of the lens, where the one or more sidewalls extend upward, away from the lens to define a cavity, and a plurality of LEDs having primary light axes extending inward into the cavity. The plurality of LEDs are coupled to the one or more sidewalls and positioned to illuminate the lens from behind with a uniform distribution of light when engaged.

Abstract: A lighting fixture includes a core member, a first elongated lamp extending outwardly from the core member, a second elongated lamp extending outwardly from the core member, a cap coupled to at least one of the first elongated lamp and the second elongated lamp, and a connector selectively coupling at least one of the first elongated lamp and the second elongated lamp to the core member. A space is defined between the first elongated lamp and the second elongated lamp. The first elongated lamp and the second elongated lamp are positioned such that the space at least one of (a) allows debris to pass therethrough and (b) increases the heat transfer coefficient of the first elongated lamp and the second elongated lamp by at least reducing an overlap between boundary layers, developed from natural convection, associated with the first elongated lamp and the second elongated lamp.

Abstract: A retrofitting kit for retrofitting an existing troffer light fixture having a troffer housing. The kit includes an adaptor bracket and a door assembly. The adaptor bracket includes a channel configured to rest on a T-bar of a ceiling system between the T-bar and the troffer housing, a slot configured to receive a portion of a troffer door assembly, and a latch surface configured to engage with a latch. The door assembly includes a latch configured to engage the latch surface of the adaptor bracket, a hinge configured to interface with the slot of the adaptor bracket, a housing including the latch and the hinge, and a light source within the housing.
