  • Patent number: 11540364
    Abstract: A lighting system includes lighting fixtures and a lighting controller that sends commands and data over an AC power line to power and control the lighting fixtures. Lighting themes are uniquely programmable color and intensity that are applied to a collection of lighting groups to achieve different lighting modes instantly, without the delay that programming each lighting fixture individually incurs. The groups of lighting modules receive theme lighting information over the power line and store the theme information in memory. The lighting controller sends a single command to the collections of the lighting groups to apply the theme or a multiple of themes to run in sequence as a pattern. Each lighting module retrieves and applies the theme information associated with the pattern.

  • Patent number: 11490495
    Abstract: An LED sticker is disclosed that receives an NFC transmission from a nearby smartphone to energize LEDs in the sticker. A spiral (or loop) antenna is used in the sticker to generate power from the NFC transmission. The NFC signal is at 13.56 MHz, which is the resonant frequency of the NFC antenna circuit in the smartphone. The LED portion is formed by sandwiching pre-formed microscopic LEDs between two conductive layers to connect the LEDs in parallel. The conductive layers form a relatively large integral capacitor that is used to achieve the 13.56 MHz resonant frequency. So no additional capacitor is needed in the circuit to achieve a resonance of 13.56 MHz. This greatly reduces the design requirements of the antenna. The LED sticker may also contain an NFC tag having its own independent loop antenna and NFC chip. Various practical applications of the LED sticker are disclosed.
