The present invention relates to a controller (1) for a component of a lighting system, which controller has a transponder (9), a control device (10), and at least one mechanical element (11...14). The transponder (9) receives data from a transmitter by means of an antenna (8), at least when the controller (1) is switched off, and stores said data. The mechanical element (11...14) is designed to disrupt or damage the antenna (8) when the controller (1) is connected to the component. The control device (10) reads the data stored in the transponder (9) at least after the controller (1) is switched on in order to use it for controlling the component to be controlled by the controller (1).

A light source drive system and a failure reporting method thereof. The light source drive system includes a control circuit and a drive circuit module. The driving circuit module has at least one light source driving circuit connected with the control circuit through a fault transmission line. The light source drive circuit has a fault arbitration circuit, including: a detection circuit, a fault reporting circuit, a switch and a fault control circuit. The fault control circuit initiates the counting duty cycle when the fault condition occurs, and controls the switch to be on in the detection time and the switch to be off in the delay time. The fault control circuit controls the detection circuit to detect a first level of the fault transmission line in the duty cycle, and outputs the detection time of different durations of time according to the different types of fault conditions.
