Patent ID: 7639219

Claim:
A method for creating a bright strobed light comprising over-driving at least one super-luminescent light emitting diode having a maximum forward continuous current rating, into forward biased conduction with a current of at least five times said maximum forward continuous current rating, and further comprising providing: (a) a circuit for over-driving said at least one super-luminescent light emitting diode; (b) a power supply that provides a pulse width modulated signal; (c) an analog memory connected to said power supply; (d) a pulse generator comprising a window comparator engaged with said analog memory and responsive to a portion of said pulse width modulated signal; and (e) a power driver controlled by the output of said pulse generator and operably connected with said at least one super-luminescent light emitting diode and with said power supply so as to energize said at least one super-luminescent light emitting diode with a current having a magnitude above said maximum forward continuous current rating; and applying a pulse width modulated signal from said from said power supply to said circuit.
