Abstract: A luminaire includes a body, with first and second surfaces that define an elongate interior cavity between the first and second surfaces, the elongate interior cavity being sized to receive one or more elongate light sources; an elongate lens that is removably securable to the body to at least partially cover the elongate interior cavity; and at least one lens retainer disposed at a first end of the elongate interior cavity, where the lens retainer includes a frame including a first frame end and a second frame end, at least a first spring lever disposed between the first and second frame ends, where the at least first spring lever is biased towards a second end of the elongate interior cavity that is opposite the first end of the elongate interior cavity; where the elongate lens is snugly retainable on the body using the bias provided by the spring lever.

Abstract: A luminaire (100) and a lens retainer (160) are disclosed. Such a luminaire may include: a body (110), with first and second surfaces (115, 120) that define an elongate interior cavity (125) between the first and second surfaces, the elongate interior cavity being sized to receive one or more elongate light sources(130i-n); an elongate lens (135) that is removably securable to the body to at least partially cover the elongate interior cavity; and at least one lens retainer (160) disposed at a first end (127) of the elongate interior cavity, where the lens retainer includes: a frame (165) including a first frame end (167) and a second frame end (169), at least a first spring lever (170) disposed between the first and second frame ends, where the at least first spring lever is biased towards a second end of the elongate interior cavity that is opposite the first end of the elongate interior cavity; where the elongate lens is snugly retainable on the body using the bias provided by the spring lever.

Abstract: Multiboard power connector (1) including a housing with a plurality of insertion points to receive multiple circuit boards. The circuit boards, received into the insertion points (12), come into electrical contact with two rails, the rails carrying opposing charges. The rails comprise a first rail and second rail. The first rail defines a longitudinal axis and a first plurality of terminals, while the second rail is divided into at least two portions that are disposed on opposite sides of the first rail, with a second plurality of terminals extending from the two portions. The first plurality of terminals and second plurality of terminals alternate on each side, such that a plurality of terminals, one from each rail, is disposed adjacent to each insertion point. A circuit board, being received at the insertion point, thus contacts one terminal from each rail and thus receives power.

Abstract: The invention provides a troffer-based lighting arrangement (100) comprising end plates (1100) and a lighting unit (1200) configured between said end plates (1100), wherein the lighting unit (1200) comprises a grounding point (1207) and head ends, wherein the end plates (1100) are associated with the respective head ends via connectors (1300), wherein the lighting unit (1200) and end plates (1100) are in physical contact with each other for providing grounding continuity between the lighting unit (1200) and the end plates (1100), and which connectors (1300) comprise head end locking tabs and end plate locking slots (1103), wherein the locking tabs reside in the respective locking slots (1103).

Abstract: The invention provides a troffer-based lighting arrangement (100) comprising a troffer, a lighting window (140), and a lighting window retainer (150) configured to retain said lighting window (140) attached to said troffer, wherein the lighting window retainer (150) comprises a part (151) configured to host part of said lighting window (140), and wherein the lighting window retainer comprises a retainer opening (152), wherein the troffer comprises a troffer opening (132), and wherein the retainer opening (152) and the troffer opening (132) are configured in gaseous communication with each other.

Abstract: The invention provides a troffer-based lighting arrangement (100) comprising end plates (1100) and a lighting unit (1200) configured between said end plates (1100), wherein the lighting unit (1200) comprises a grounding point (1207) and head ends, wherein the end plates (1100) are associated with the respective head ends via connectors (1300), wherein the lighting unit (1200) and end plates (1100) are in physical contact with each other for providing grounding continuity between the lighting unit (1200) and the end plates (1100), and which connectors (1300) comprise head end locking tabs and end plate locking slots (1103), wherein the locking tabs reside in the respective locking slots (1103).

Abstract: A vandal resistant lighting fixture including a base with a first side wall and a flange extending from the first side wall; a cover having a second side wall having interior and exterior peripheries and a cap extending from the second side wall, the cap having an opening through which light from an illumination source may pass; a securing mechanism rotatably securing the cover to the base when the cover is rotated in a first direction relative to the base to a secured position; and/or a magnetically operable latching mechanism having latched and unlatched positions. With the cover in the secured position, the latching mechanism prevents rotation of the cover in a second direction opposite the first direction when the latching mechanism is in the latched position. A corresponding magnetic key may be configured to provide a magnetic force to toggle the latching mechanism between the latched and unlatched settings.
