  • Patent number: 10154553
    Abstract: An LED driver uses a switch mode power supply either to provide a regulated LED current (in a first mode) that connects directly to the LED arrangement or a regulated LED voltage (in a second mode) to an LED output terminal. An auxiliary power supply is either based on an auxiliary secondary side (i.e. an auxiliary secondary side winding) when in the first mode, or it is based on the regulated LED voltage when in the second mode. The LED driver further comprises an input adapted to receive a standby command for the driver, wherein the main controlling unit is adapted to control the driver in the second mode when receiving the standby command for the driver. In this way, the driver has a single shared stage which can operated in a regulated current (i.e. constant current) mode to drive the LED arrangement directly or a regulated voltage (i.e. constant voltage) mode. It can adaptively change between modes to improve the standby power efficiency. When the load is turned on (e.g.
