Abstract: A lighting device includes one or more LED modules, each of which includes a group of LED sets positioned on a substrate. Each LED set includes two or more sections, optionally under a single lens. The sections are individually controlled by a controller of the lighting device or an external controller. The beam spread, beam shape, or both of the light emitted by the device may be controlled by selectively activating the sections of each LED set.

Abstract: A lighting device includes one or more LED modules, each of which includes a group of LED sets positioned on a substrate. Each LED set includes two or more sections, optionally under a single lens. Each section is configured to emit light of different luminescent properties, such as different colors or different color temperatures. The color, color temperature or other characteristics of light emitted by the device is controlled by selectively activating the sections of each LED set.

Abstract: A lighting device control system includes a lighting device that includes a communication interface, an optical radiation source, and a fixture controller. The system also may include a gateway controller that is in communication with the lighting device and one or more other lighting devices. The fixture controller or gateway controller identifies that a portable electronic device is in a proximate communication range. The fixture or gateway controller also receives a light operation request from the portable electronic device. The light operation request includes one or more settings for one or more optical characteristics of light that the optical radiation source may emit. The fixture controller determines whether the portable electronic device is authorized to implement the request. In response to determining that the device is authorized, the fixture controller will cause the optical radiation source to emit light that exhibits the optical characteristic(s).

Abstract: A system controls lighting devices at one or more light-enabled facilities, each of which includes gateway controller at each facility. A facility's gateway controller pairs with a portable electronic device when the portable electronic device arrives at the facility. The gateway controller portable electronic device receives light operation requests from the portable electronic device upon arrival, or from the remote server before arrival. Each light operation request adjusts various hardware settings of the lighting devices to alter the optical characteristics of emitted light at various times. The system also may use geolocation data to identify and schedule lighting services at various light-enabled facilities in a geographic area.

Abstract: A system for controlling lighting devices at one or more light-enabled facilities includes a portable electronic device with an app that communicates with a gateway controller at each facility, and/or a remote server. The portable electronic device pairs with a gateway controller upon arrival at the facility. The portable electronic device may receive available scenes from the gateway controller upon arrival, or from the remote server before arrival, and it may select scenes for the gateway controller to implement. Each scene will adjust various hardware settings of the lighting devices to alter the optical characteristics of emitted light at various times. The system also may use geolocation data to identify and schedule lighting services at various light-enabled facilities in a geographic area.

Abstract: A system of networked lighting devices includes a central controller and a group of lighting devices. The central controller includes a processor, first and second communication interfaces, various lighting devices and a communication link. The first communication interface includes input ports and a multiplexer configured to receive signals from the input ports and combine the received signals into a multiplexed signal. The second communication interface includes one or more antennas and is configured to receive the multiplexed signal from the multiplexer and transmit the multiplexed signal via the antenna(s). Each lighting device includes a fixture controller, one or more lighting modules, and a communication interface. The communication link transmits the multiplexed signal between one or more of the lighting devices and at least one of the communication interfaces of the central controller.

Abstract: A recessed light fixture includes an LED module, which includes a single LED package that is configured to generate all light emitted by the recessed light fixture. For example, the LED package can include multiple LEDs mounted to a common substrate. The LED package can be coupled to a heat sink for dissipating heat from the LEDs. The heat sink can include a core member from which fins extend. Each fin can include one or more straight and/or curved portions. A reflector housing may be coupled to the heat sink and configured to receive a reflector. The reflector can have any geometry, such as a bell-shaped geometry including two radii of curvature that join together at an inflection point. An optic coupler can be coupled to the reflector housing and configured to cover electrical connections at the substrate and to guide light emitted by the LED package.

Abstract: A light module includes a heat sink and one or more light sources coupled within a heat sink cavity formed therein. The heat sink includes an internal surface surrounding the cavity. The internal surface includes a mounting region, a reflector region extending from the perimeter of the mounting region to a distal end, and a decorative region extending from the distal end to a second distal end. The light module includes multiple mounting pads coupled circumferentially around a portion of the heat sink. The mounting pads are configured to facilitate the heat sink being coupled within different housing diameter sizes. The light module includes a trim ring integrally formed with the heat sink and extending radially outward from one end of the heat sink.
