摘要：The present invention relates to a driver device () for driving a load (), in
particular an LED unit comprising one or more LEDs, said driver device comprising inputterminals () for receiving an input voltage (V) from an external power supply (), outputterminals for providing an output voltage to the load () for driving the load (), a converterunit () for converting the input voltage (VI ) to a converted voltage (VI ) and for providingthe converted voltage (VI ) to internal connection elements () of the driver device (), asignal control device () for applying an electrical signal (I) to at least one of theconnection elements (), and a detection circuit for detecting a phase angle of the inputvoltage (VI ) by measuring a voltage drop of the converted voltage (VI ) caused by theelectrical signal (I).
