Abstract:
A method for generating a momentary peak emission of luminous flux by an incandescent lamp, including:(a) applying a capacitive discharge across a first electrode and a second electrode of said incandescent lamp,(b) setting the ratio of the values of the peak voltage of said capacitive discharge with respect to the nominal direct current voltage of said incandescent lamp at about equal to 3.2, and(c) with respect to the repetition rate of said capacitive discharge, setting the time constant and extent of the discharge of said capacitive discharge resulting in equal values of the momentary peak and nominal direct current temperature of the filament of said incandescent lamp,whereby the ratio of the values of said momentary peak emission of luminous flux with respect to the nominal direct current luminous flux emission of said incandescent lamp is generally greater than 2:1, and the service life compared to the nominal direct current service life of said incandescent lamp is only moderately reduced.
