  • Patent number: 11240897
    Abstract: Two-wire dimmer operation includes controlling conduction of power to a lighting load. In one aspect, based on a conduction angle adjustment, power supply voltage is monitored and a maximum conduction angle is established based thereon. In another aspect, a dimming level signal is received and a dimming level for a dimmer is set based on the received dimming level. The dimming level signal indicates a desired dimming level for a dimmer, and a maximum value for the dimming level signal is based on a dimmer power supply voltage. In yet another aspect, based on detecting an adjustment to increase a conduction angle of a dimmer, the conduction end angle is increased and the conduction start angle is also increased. This results in a net increase in the conduction angle for controlling operation of the dimmer.

  • Patent number: 10568185
    Abstract: Two-wire dimmer operation includes applying first and second control pulses to a switching circuit controlled between ON and OFF states, the first control pulse beginning at a first starting time and extending for a first duration of time that ends at a first ending time, and the second control pulse beginning at a second starting time, after the first ending time, and extending for a second duration of time that ends at a second ending time, detecting levels of current provided to a lighting load during the first duration of time and during the second duration of time, comparing current levels determined based on applying the first and second control pulses, based on the comparing, ascertaining a load type of the lighting load, and selecting, based on the ascertained load type, parameters that control dimming operation of the dimmer.

  • Patent number: 9916946
    Abstract: A dimmer switch includes a housing having a frame having a single actuator opening therethrough. The opening has first and second portions. A controllably conductive device is disposed in the housing for adjustably controlling electrical power to a load. A pivotable toggle actuator is accessible through the first portion of the single actuator opening and pivotable between a first and second positions by a user. A slidable dimmer actuator is accessible through the second portion of the single actuator opening. The slidable dimmer actuator is slidable linearly within the second portion of the single actuator opening anywhere between first and second positions by a user. The pivotable toggle actuator is operable for controlling the controllably conductive device to turn on and off power to the load, and the slidable dimmer actuator is operable for controlling the controllably conductive device to adjustably control the level of power to the load.
