  • Publication number: 20180324929
    Abstract: Techniques are disclosed to operate a luminaire so as to reduce glare experience by an occupant within an area illuminated by a luminaire. The luminaire includes individually operated light sources. An image capture device is deployed for capturing an image of an area. Operatively coupled to the luminaire and the image capture device is a computing system. The computing is configured to reduce glare by adjusting a light intensity of a light source of the luminaire. These adjustments are based on, for example, a position of an occupant within the area and a direction in which the occupant is facing relative to the luminaire, and/or a position of an indirect glare source.

  • Publication number: 20180302161
    Abstract: Techniques are disclosed for projecting visible cues to assist with light-based communication (LCom), the visible cues referred to herein as visual hotspots. The visual hotspots can be projected, for example, using a luminaire that may be LCom-enabled. The visual hotspots may be projected onto the floor of an area including an LCom system. The visual hotspots can be used for numerous benefits, including alerting a potential user that LCom is available, educating the user about LCom technology, and assisting the user in using the LCom signals available in the area. The visual hotspots may include images, symbols, cues, characters (e.g., letters, words, numbers, etc.), indicators, logos, or any other suitable content. In some cases, the visual hotspots may be interactive, such that a user can scan the hotspot to cause an action to occur (e.g., launch an application or website).

  • Publication number: 20180292520
    Abstract: Systems, methods, and software for determining whether or not a monitored space is occupied by one or more humans and/or animals. In some embodiments, one or more radio-frequency (RF) receivers monitor(s) one or more RF frequencies for changes in received signal strength that may be due to changes in occupancy of the space being monitored. The received signal strength is analyzed using nonparametric online change-point detection analysis to determine change-points in the received signal(s). One or more statistical measures of the received signal(s), such as mean and variance, are used in conjunction with the change-point detection to determine a probability that the occupancy of the monitored space has changed. In some embodiments, additional sensors and/or machine learning can be used to enhance the performance of the disclosed occupancy-detection methodologies.

  • Patent number: 10094527
    Abstract: A projection headlamp (12) has a reflector (28) reflecting light emitted from a light engine (20); a projector lens (30) projecting reflected light from the reflector (28); and a shutter (22) disposed between light engine (20) and projector lens (30), the shutter (22) having an upper edge (44) defining a cut-off to generate a low beam pattern by obscuring a portion of the projector lens (30) from the reflected light and to selectively emit the reflected light through the projector lens (30) in a low-beam light distribution pattern. The shutter (22) further includes a partially light-transmissive shutter bump (56) extending above the upper edge (44) which attenuates light emitted from the projector lens (30) in a predefined area of the low-beam pattern. Light intensity at the 0.86D, 3.5L NHTSA test point (112) is attenuated to below maximum photometric intensity (12,000 candela), avoiding glare.

  • Patent number: 10097265
    Abstract: Techniques are disclosed for position-based actions using light-based communication (LCom). LCom signals can be used to encode or otherwise provide data which in turn can be used to help determine the position of a device receiving those LCom signals. Therefore, LCom can be used to facilitate various actions based on, for example, the position of an LCom receiver determined using data received via the LCom signals. There are numerous use cases for position-based actions using LCom, such as security applications, check-in applications, payments based on location, permissions, and access to information that can all be tied to a location. Actions may include temporarily disabling or enabling the LCom receiver hardware or software (such as disabling device cameras in high security areas), providing another security layer as a result of knowing the device position, and using the LCom receiver position as a part of a larger process.

  • Publication number: 20180288839
    Abstract: A constant output current LED driver is disclosed. The driver is capable of operating with a wide range of input direct current (DC) voltage, and is configured with a full bridge inverter, an auxiliary circuit, and a voltage current converter. The full bridge inverter and auxiliary circuit collectively operate to provide a phase shift controller for the LED driver system. The LED driver operates under zero voltage switching (ZVS) for all switches in the LED driver circuit for all of the input voltage levels and for all of the output voltage levels. By maintaining ZVS in all conditions, the system can operate at very high frequency and be compact yet still achieve high power density. The resulting topology is applicable for a wide range of constant output current LED drivers. Switchable loads other than LEDs can also be driven.

  • Publication number: 20180285650
    Abstract: Techniques are disclosed for detecting changes in occupancy as well as the number of occupants within an area. Detection of one or more occupants entering or leaving the area may be accomplished using a sensor having a quantity of pixels. The pixels may be configured to receive thermal energy emitted from one or more objects present in the area, including from one or more occupants. In response to receiving the emitted thermal energy, the sensor may be configured to create thermal images of the area. These thermal images may include a plurality of thermal intensity values associated with one or more pixels of the sensor. Two or more thermal images can be compared to identify a change in thermal intensity values. A change in the occupancy of the area may be determined by based on the identified change in thermal intensity values.

  • Patent number: 10075234
    Abstract: Techniques are disclosed for emitting position information from luminaires. Luminaire position information may be emitted via a light-based communication (LCom) signal that comprises data including the position information. The data may include relative and/or absolute position information for the luminaire and may indicate the physical location of the luminaire. Relative position information for the luminaire may include coordinates relative to a point of origin within the environment. Absolute position information for the luminaire may include global coordinates for the luminaire. In some cases, the absolute position information for a luminaire may be calculated using position information for the luminaire relative to a point of origin and the absolute position of the point of origin. The data may also include an environment identifier, which may indicate a map to use for the interpretation of position information for the luminaire. The techniques can be used for both stationary and mobile luminaires.

The disclosed techniques can be used, for example, to reduce the time, labor, and expense associated with programming and re-programming a luminaire with a luminaire position, and to increase the flexibility of navigation system installations. In some cases, the disclosed techniques can be used, for example, to improve the precision of a luminaire position programmed into a newly installed luminaire.

    Abstract: Optical components for lighting devices and lighting devices including such components are described. In some embodiments the optical components are in the form of a lens that alter the distribution of light produced by a lighting fixture. In some embodiments, the lenses are in the form of a downlight to wallwash lens which, when placed in a downlight fixture, convert the light distribution to that of a wallwash fixture, e.g., causing the downlight to produce an off-axis light distribution, without changing the fixture. The lens includes a body with a light source facing side and an opposite room facing side having two optically active regions, each including structures that redirect a portion of light received through the light source facing side and incident thereon. The first region includes structures that redirect, via refraction, and the second region includes structures that redirect, in part via total internal reflection.
