ABSTRACT:
A high reliability portable incandescent illumination system for use in applications which require a reliable, high output light source such as heliport markers, runway lights, warning lights, road hazard and obstruction lights. The required elements of the invention are a battery to provide an energy source, a DC/DC converter to step up the battery voltage to a level required to drive a high output light source. The DC/DC converter is driven by a controller which generates a pulse stream to the DC/DC converter based upon inputs from a soft start circuit, a filament temperature sensor, an optical spectrum sensor, a power sensor and a filament break sensor. The optical spectrum sensor is coupled to the light source by a fiber optical element. An improvement in results in the performance of portable beacons by using high voltage lamps with low voltage batteries via voltage step-up electronics.
