Abstract
A system includes a switch-mode power supply for drawing low and constant current from a power source. The switch-mode power supply may charge an energy storage element with low and constant current. In a normal condition, a current driver may cause the illuminator to emit electromagnetic radiation as a plurality of flashes. In the normal condition, the system may include an average power that is less than or equal to a threshold value associated with the illuminator. In a fault condition, the illuminator may continuously emit electromagnetic radiation, at low current. In the fault condition, the switch-mode power supply may supply low and constant current to the illuminator. Similarly, in the fault condition, the system may include an average power that is less than or equal to a threshold value associated with the illuminator.
