Event and arc detection in lamps |
摘要 |
A power supply system has a battery for supplying power and a lamp having a plurality of filaments therein. Each of the filaments is connected to the battery through a filament power feed line, respectively. A switch is provided on each of the filament power feed line. A fault detection circuit measures a current that flows in a non-active filament and generates a fault signal that shuts off the switch for the filament when the current flows in the non-active filament.
