  • Patent number: 9930762
    Abstract: A controller included in a lighting control device causes a transmitter to transmit a dimming rate which is determined by schedule information stored in a storage when power saving is not instructed via a power saving instruction signal. When power saving is instructed via the power saving instruction signal, the controller calculates a dimming rate for causing a luminaire to emit light at a brightness lower than in the case of the dimming rate determined by the schedule information. When the calculated dimming rate is a dimming rate which causes the luminaire to emit light at a brightness lower than a predetermined dimming rate, the controller causes the transmitter to transmit the predetermined dimming rate.

  • Patent number: 9872352
    Abstract: A power supply circuitry compatible with both source type dimmer controls and sink type dimmer controls is provided. The power supply circuitry includes an internal voltage source, a dimmer control type detection circuit, and a configuration circuit. The dimmer control type detection circuit detects a type of a dimmer control that is electrically coupled to the power supply circuitry. The configuration circuit can turn off the internal voltage source upon determining the dimmer control is of the sink type and turn on the internal voltage source upon determining the dimmer control is of the source type. Thus, the internal voltage source may generate a voltage as the dimming control signal. The dimming control signal is fed to a microcontroller that may, for example, generate a series of pulse signals that is provided to a power converter of a load (e.g., light-emitting diode luminaries) based on the dimming control signal.
