ABSTRACT:
An incandescent radiation lamp features a novel design which provides for an infrared beam of higher radiance than similar lamps. The higher radiance beam is accomplished by a surrounding reflective screen which internally focuses the generated radiation back upon the bulb filament of the lamp. The focused radiation is then redirected by reflection from the filament, and is emitted from the lamp as an intensified beam through a small window in the surrounding reflective screen.
An added benefit of the new design is the improvement in the thermal efficiency of the lamp, so that less power is required for its operation.
