摘要：Driver circuitry is coupled between a power supply and at least one LED in asolid-state lighting fixture, such that a non-isolated direct current (DC) path exists
between the power supply and the at least one LED. The driver circuitry is configured toreceive an AC input voltage and generate a driver output current for driving the at leastone LED from the AC input voltage. By using driver circuitry that is non-isolated from theat least one LED in the solid-state lighting fixture, the efficiency of the driver circuitry maybe increased, while simultaneously reducing the cost and complexity of the drivercircuitry compared to conventional driver circuitry.
