  • Patent number: 10842003
    Abstract: An entertainment system plays out audio and/or visual media into a region, wherein the media further comprises metadata specifying an optimal ambience setting for the media. A lighting system controls ambient lighting in the region, the lighting system comprising one or more luminaries, and the one or more luminaires comprising at least one moveable luminaire. Further, a controller determines one or more positioning instructions to specify a target position of the at least one moveable luminaire in order to achieve the optimal ambience setting specified in the metadata, and output the one or more positioning instructions in order to cause the at least one moveable luminaire to be repositioned. The controller then controls the ambient lighting by varying one or more light characteristics of the ambient lighting based on the metadata, such that the ambient lighting corresponds to the playing out of the media.

  • Patent number: 10820389
    Abstract: An analogue dimmer driver for driving an LED lighting element (54) to generate coded light comprises an output component (54) which provides a primary current (ipr), a capacitor (53) connected to the output component, a switch (S1) via which the lighting element is connectable to the current source in parallel with the capacitor. Switching is performed by periodically opening and closing the switch to code information into light generated by the lighting element. The output component has an input configured to receive a dimming signal. Responsive to a change in the dimming signal: i) the primary current is increased so as to increase the average power of the generated light and ii) the duty cycle of the switching is increased by an amount sufficient to prevent the peak level of the current though the lighting element when the switch is closed (ipr+idis) from exceeding a predetermined level (inom).
