MINIATURE METAL HALIDE LAMPS: Ⅱ. A STUDY OF FLICKER AND FLARE

摘要

Of the many factors that influence stability (lamp design, lamp thermal balance, ambient conditions, orientation, and ballast operation) we specifically identify two that have a significant effect in low wattage metal halide lamps: 1. The presence of cold pockets along the cathode shank produces erratic flaring and contributes to flicker. 2. Addition of cesium iodide to the halide dose significantly reduces flicker noise related to arc termination.
