  • Patent number: 11652287
    Abstract: A luminaire includes a light source positioned at a first level within a luminaire housing. The luminaire also includes a trim component positioned at a second level of the luminaire housing different from the first level. The trim component extends into a room from a ceiling surface and includes an aperture antenna that receives wireless signals and transmits wireless signals. Further, the luminaire includes a communication module that communicates wirelessly with one or more devices remote from the luminaire by controlling excitation of the aperture antenna.

  • Patent number: 11268690
    Abstract: A lighting system includes a first luminaire. The first luminaire includes a first light source that generates a first light output. The first luminaire also includes a first visual feedback response source that generates a first visual feedback response output. Additionally, the first luminaire includes a first speaker that generates a first audio output. Further, the lighting system includes a second luminaire. The second luminaire includes a second light source that generates a second light output and a second visual feedback response source that generates a second visual feedback response output. Furthermore, the second luminaire includes a second speaker that generates a second audio output. The second audio output is different from the first audio output such that the first speaker and the second speaker output different audio components of a multichannel audio protocol output.

  • Patent number: 10952292
    Abstract: Certain aspects involve lighting systems in which an intensity can be selectively modified. For instance, a lighting system includes a light source and a programmable device. The programmable device is configured to detect an input resistance and cause a particular current to flow through the light source, thereby causing the light source to emit a particular lumen intensity corresponding to an input resistance.

  • Patent number: 10856384
    Abstract: Certain aspects involve lighting systems in which the color temperature of the illumination can be selectively modified. In one example, a lighting system can include a set of light sources. The lighting system can also include a switching device. The switching device can connect different light sources from the set into light-source combinations having different color temperatures, respectively. A light-source combination can include two of the light sources connected in series.

  • Patent number: 10448471
    Abstract: Certain aspects involve lighting systems in which a dimming curve of the illumination can be selectively modified. For instance, a lighting system includes a light source configured for emitting light at a target color temperature and a switch configured to receive a selection of a dimming curve from a predefined set of dimming curves. When in a first position, the switch configures the light source to adjust a lumen intensity of the light source according to a dimming adjustment signal and a first dimming curve. When in a second position, the switch configures the light source to adjust the lumen intensity according to a dimming adjustment signal and a second dimming curve that is different from the first dimming curve.

  • Patent number: 10299337
    Abstract: Certain aspects involve lighting systems relating to control of light fixture dimming. For instance, a lighting system may include a first light source that outputs a first light color and a second light source that outputs a second light color. The lighting system also includes a switching device that couples and decouples the second light source in parallel with the first light source. The switching device includes a first setting that couples the second light source in parallel with the first light source and enables a variable color dimming operation. The switching device also includes a second setting that decouples the second light source from the first light source and enables a static color dimming operation.
