Plural Load Device Regulation Patents (Class 315/294)
  • Patent number: 11013077
    Abstract: An LED driver has outputs to drive LEDs in groups of different colour temperatures. An input is configured to receive setpoint information, and a control device is configured to determine a combined LED setpoint intensity for the groups and a combined LED setpoint colour temperature for the groups, from the LED setpoint information. If the LED setpoint intensity is above a threshold, the control device operates the LED driver outputs to mix the LED group outputs to jointly achieve the LED setpoint intensity and the LED setpoint colour temperature. If the LED setpoint intensity is below the threshold, the control device selects a single LED group, operates the LED driver output associated with the selected LED group to drive that one LED group at the LED setpoint intensity, and operates the remaining LED driver outputs to drive the remaining LED groups at zero LED intensity.

  • Patent number: 10652986
    Abstract: A method and system for allowing automatic provisioning of a LED lamp in a dimmer system. The dimmer powers the lamp through a switched AC line. A wireless link serves for information exchange between the dimmer and the lamp. When the lamp is turned on by the dimmer, it starts a short waiting period in which it expects to wirelessly receive from the dimmer a provisioning message including a dimmer identification, which it saves to identify dimming messages the dimmer. Another aspect of the invention is disclosed in the above dimmer system, wherein the lamp comprises a backup battery. The dimmer wirelessly informs the lamp upon voltage drops at its input caused by user OFF actions and/or by AC supply outage. The lamp is configured to assume backup mode only upon detecting, based on the above information, a voltage drop at its input caused by an AC supply outage.

  • Patent number: 10622887
    Abstract: A zero current detector control circuit controls a voltage applied to a zero current detector (ZCD) input of a power factor corrector integrated circuit (PFC IC) that produces a driver output having an on time and an off time. The zero current detector control circuit includes a voltage detection input circuit coupled to a rectified AC input voltage. The detector control circuit generates a control voltage applied to a control terminal of an electronic switch. When the rectified AC input voltage has a phase angle in a first portion or in a last portion of a half-cycle, the electronic switch conducts to connect a capacitor to the ZCD input of the PFC IC. The capacitor causes the fall time of the trailing edge of a pulse applied to the ZCD input to increase, which causes the off time of the driver output of the PFC IC to increase.
