  • Patent number: 9420650
    Abstract: Some embodiments relate to dimmer control circuitry for LED lighting, comprising: phase control circuitry to control the supply of voltage to at least one LED load, wherein the phase control circuitry comprises an AC switch to selectively provide voltage to the LED load for a first portion of a half cycle of an AC supply voltage, and a drive component to drive the AC switch so that the AC switch remains on for the first portion of the half cycle; and load switching circuitry to couple a dissipative load to an output of the AC switch during a second portion of the half cycle, wherein the second portion overlaps with the first portion.
