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 signal guide for a sensor device is disclosed herein. The signal guide can include a base having a number of proximal apertures, where at least one of the proximal apertures is configured to be disposed proximate to at least one transceiver of the sensor device. The signal guide can also include a body disposed adjacent to the base, where the body includes at least one main channel, where the at least one main channel is configured to transmit at least one signal between the at least one main channel and the proximal apertures. The signal guide can further include a distal end disposed adjacent to the body opposite the base, where the distal end includes at least one distal aperture, where the at least one distal aperture is configured to transmit at least one signal between the a main channel and an ambient environment.
Abstract:
A signal guide for a sensor device is disclosed herein. The signal guide can include a base having a first proximal aperture, where the first proximal aperture has a first cross-sectional profile, where the first proximal aperture is configured to be disposed proximate to a first transceiver element of the sensor device. The signal guide can also include a body disposed adjacent to the base, wherein the body comprises a first main channel that adjoins the first proximal aperture. The signal guide can further include a distal end disposed adjacent to the body opposite the base, where the distal end includes a first distal aperture that adjoins the first main channel, where the first distal aperture has a second cross-sectional profile, where the first distal aperture is configured to be disposed proximate to an ambient environment.
Abstract:
A sensor device is disclosed herein. The sensor device can include a sensor having a first mode of operation and a second mode of operation, wherein the sensor, when in the first mode of operation, transmits a first plurality of signals during a first period of time, and wherein the sensor, when in the second mode of operation, receives a second plurality of signals during a second period of time.
Abstract:
A lighting system can comprise an edgelit panel, for example a lightguide that may have a panel or slab shape with an edge that receives light from an array of light emitting diodes extending along the edge. The lightguide can guide the received light towards an opposing edge of the lightguide and gradually release light to provide illumination. An optic can manage light that reaches the opposing edge of the lightguide, for example via softening, spreading, concentrating, or diffusing the light. The optic can be mounted to or integrated in the opposing edge of the lightguide.
Abstract:
A lighting device includes a plurality of light emitting diodes (LEDs) configured to emit a light. The lighting device further includes a color controller configured to repeatedly assert and deactivate a control signal to control whether one or more LEDs of the plurality of LEDs are turned on or turned off. The color controller asserts the control signal for a first time period and deactivates the control signal for a second time period, where a color of the light emitted by the plurality of LEDs depends on the first time period and the second time period. The color controller changes the color of the light emitted by the plurality of LEDs by changing one or both of the first time period and the second time period.

Abstract:
A recessed light fixture includes an LED light source and a reflector extending 360 degrees around a center line of light output from the light source. A cross-sectional geometry of the reflector includes a bell-shaped curve with two radii of curvature that join together at an inflection point. One of the radii defines a top portion of the curve, which is disposed above the inflection point and reflects light in a concentrated manner to achieve desired light at higher angles. The other radii defines a bottom portion of the curve, which is disposed below the inflection point and is more diverging than the top portion.
