    Abstract: Two-layer lighting control network systems and methods are disclosed. Embodiments include client lighting devices having a first type of radio for receiving wireless control signals, a lighting controller including a second type of radio, and a hub lighting device having a second type of radio for wireless communication with the lighting controller and a first type of radio for communicating with the client lighting devices. The first wireless network includes the first type of radio of hub lighting devices and the first type of radio of client lighting devices, and the second wireless network includes the second type of radio of the lighting controller and the second type of radio of the hub lighting devices. In at least one embodiment, client lighting devices are lamps having the first type of radio. In other embodiments, hub lighting devices are light fixtures having the first and second types of radios.

    Abstract: Example embodiments include modular lighting fixtures and methods for forming the same. 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.

    Abstract: Luminaires that simultaneously illuminate a support surface (for example, a floor) and the surface to which the luminaires are mounted (for example, a ceiling) and methods for manufacturing the same are disclosed. 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.

    Abstract: An illustrative wireless controller for a lighting fixture includes an actuator module, a control module, and optionally a sensor module. The control module includes a radio, an antenna, a user interface, and a controller. A control housing defines an enclosure for the control module and defines a male fitting for mounting the control housing to an opening defined through the light fixture housing. The actuator module includes an AC-to-DC converter, a power monitoring circuit, a load switching circuit, and a dimming control circuit. An actuator housing defines an enclosure for the actuator module and for mounting the actuator housing inside the fixture housing. The control module receives wireless lighting control signals, decodes the wireless lighting control signals, and controls the actuator module based on at least the decoded wireless lighting control signals, to control the electrical power supplied by a power converter to a lighting fixture lamp.

    Abstract: An illustrative bi-level dimming controller for coupling to a dimming control input of a lighting driver includes a dimming preset selector for setting a preset dim level, and a dimming control circuit having variable impedance and providing a constant dimming voltage output for a preset dim level, even if the current supplied to or impedance coupled to the dimming controller changes. The dimming control circuit is responsive to the preset dim level to drive a dimming voltage output proportional to the preset dim level. The dimming controller may also include a dim enable circuit responsive to a detection signal to selectively couple and uncouple the dimming signal output with the dimming control input of the lighting driver, thereby providing switching between a preset dim level and a full light level. The detection signal may be electrically isolated from the dimming voltage output.
