Abstract

586130 Disclose is an LED driver for a traffic lantern. The driver includes a current mirror (14) adapted to control the current through an LED (18) of the lantern. A fault detector (20) is connected to an output (16) of the current mirror (14) and the LED (18) and is adapted to indicate a fault condition if the voltage measured is outside a predetermined range. A voltage sensor (26) is arranged to provide an output voltage proportional to the average voltage of other LED drivers for the lantern which are not connected to faulty LEDs. The fault detector (20) monitors the output voltage (16) of the current mirror (14) and produces first (22) and second (24) outputs. The first output (22) is fed to a fault circuit in which the first output (22) is combined with the first outputs from a plurality of other LED drivers and then compared. The second output (24) is fed to the voltage sensor (26) arrangement which is also fed an output voltage (28) of the LED (18).
