Abstract: An illustrative light fixture provides an emitter housing and a driver housing in a single fixture with an airflow channel defined between the emitter and driver housings. The airflow channel minimizes thermal conduction between the emitter and driver housings, and maximizes thermal convective cooling for at least one of the emitter housing and driver housing. The emitter housing includes vertical fins extending into the airflow chamber. The left and right sides of the emitter and driver housings define top and bottom edges that are respectively coplanar with the top and bottom edges of the vertical fins.

Abstract: A modular light fixture includes an elongate light fixture base having a longitudinal axis and a plurality of light fixture modules. Each light fixture module includes a housing having an open face, and a light emitting device positioned inside the housing. The modular light fixture also includes a light emitting device driver configured for driving the light emitting devices. The light fixture modules are independently mounted to the light fixture base and extend perpendicularly from opposing sides of the light fixture base with the open faces facing a common direction to produce an initial light distribution pattern. Each light fixture module has a housing adjustment feature for independently pivoting the light fixture module about a pivot axis parallel to the longitudinal axis to modify the initial light distribution pattern. The modular light fixture includes a planar configuration in which the light fixture module housings are oriented along a common plane.

Abstract: A light fixture includes a housing enclosing a light source. The housing defines an opening therethrough. A plug, which is receivable within the opening, includes a face having a central knockout portion. A perimeter of the knockout portion defines an opening size smaller than an opening size of the opening. According to alternative configurations, the plug may be removed from the opening or only the knockout portion may be removed from the plug while leaving a remainder of the plug in the opening. As such, different sized openings through the light fixture housing may be provided for installation of various light fixture accessories.

Abstract: An illustrative lighting system provides a single light housing and an associated lens cover that together interchangeably receive one of a selection of heat sink trays and one of a selection of light reflectors. Each of the selection of heat sink trays includes a different number and/or orientation of light emitter packages. Each the selection of light reflectors includes openings and surfaces matching the number and orientation of light emitter packages for one of the selection of heat sink trays.

Abstract: An illustrative mounting arm for a light fixture provides multiple tilt angles based on the selected orientation of components of the mounting arm. The mounting arm includes a first and second arm portion, each having opposite ends oriented at different relative angles to provide the multiple tilt angles for the light. A support end arm or second arm portion connects directly or indirectly to a wall or other support structure. An intermediate or first arm portion couples between the second arm portion and a mounting pad portion of the light fixture. Each of the first and second arm portions are rotatable in orientation, thus changing the orientation of the angle ends, each combination of possible arm portion orientations displacing the light fixture and therefore the illumination pattern at a different elevation angle relative to the support structure.
