  • Patent number: 11002424
    Abstract: A system can configure a luminaire for providing illumination of a selected color temperature, a selected lumen output, or a selected photometric distribution. The luminaire can comprise at least two light sources that have different illumination characteristics, for example different color temperatures, different lumen outputs, or different photometric distributions. The system can configure the luminaire to operate a first of the two light sources, a second of the two light sources, or both of the light sources based on an input. When the luminaire is configured to operate both of the light sources, the luminaire can produce illumination having a color temperature, a lumen output, or a photometric distribution that is different than either of the two light sources.

  • Patent number: 10986713
    Abstract: A retrofit lamp is to be used with a ballast. A shunt switch is provided in parallel with an output load and is adapted to shunt input terminals of the lamp using pulse width control so as to tune the current through the lighting element. This current control is used to enable compatibility with different ballasts and to provide dimming control. A detection circuit is used to detect an abnormal drive condition of the retrofit lamp and the pulse width control of the shunt switch can then be overridden by holding the shunt switch at a stable state for a certain duration. This prevents overload conditions and avoids DC signals in the event of component failures.

  • Patent number: 10985930
    Abstract: The invention relates to a PoE system, which comprises a powered device (2) and a power sourcing device (1). The power sourcing device comprises one or more ports (12) and the powered device is connectable to a port of the power sourcing device by an electrical conductor (13) for conveying the sourced power along with data. The powered device comprises an interface for providing a measure of its energy consumption within the PoE system and, if it does not have the ability to measure its energy consumption, is adapted to negotiate with the power sourcing device whether the power sourcing device has the ability to measure the energy consumption of the powered device and to provide the measured energy consumption to the powered device for provision via the interface. This can make the PoE system more flexible and allow for a single “point of contact” for providing energy usage feedback.
