Some include light emitters and base members with mounting locations for the light emitters, the light emitters and base members being combinable in varying combinations with each combination producing a different lighting effect. Some embodiments include a light guide, such as a planar light guide, that receives and redirects light from the light emitters. Additional embodiments include a reflector with portions that are positioned near a mounting location where no light emitter is mounted when the reflector is mounted to a base member. Further embodiments include a reflector with portions that are positioned near the mounting locations when mounted to a base member, the portions being easily removed, such as with an unpowered hand tool, to avoid interference with a light emitting member mounted adjacent to where the removable portion would be if not removed from the reflector.

Embodiments include luminaires that divide the light from a single light emitter (which may include one or more light sources such as LEDs) into a portion directed toward the luminaire's mounting surface and a portion directed toward the support surface. Some embodiments utilize a planar light guide with the light emitter mounted adjacent one edge, which in some embodiments is the internal edge of an aperture formed in the planar light guide. In some embodiments, one surface of the light guide includes grooves that internally reflect light toward the support surface while allowing a smaller amount of light to exit the light guide toward the mounting surface, and may be grouped according to the distance separating adjacent grooves.

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: Embodiments of the present disclosure provide multi-mode phase control dimmers for lighting devices, particularly for use with wireless lighting control systems. The disclosed universal dimming devices include a load-type detection circuit for determining whether the load for connected lighting devices has an inductive characteristic. The system automatically detects the load characteristic and self-adjusts its phase-cut dimming mode in response. The disclosed solutions require minimal additional components to provide load-type detection beyond those components already included in typical phase dimming applications, particularly in a wireless lighting control environment, thereby minimizing cost. The disclosed solutions have improved reliability by detecting multiple characteristics detected for each of a plurality of AC cycles in order to reliably distinguish between load types.
