Abstract UHP‐lamps are standard for high efficient projection systems. All short arc lamps show arc instabilities. Optical integrators can successfully suppress visual effects but they are of limited use for small displays. A new technology is presented here which stabilises the lamp arc directly and keeps the good maintenance of the lamp.
