STRAPLESS MOUNT FOR A LIGHT SOURCE AND ELECTRIC LAMP HAVING THE SAME

摘要

A medium wattage ( > 175W to 400W) metal halide electric lamp is provided having a strapless mount structure for the light source capsule (10) while reliably passing standard drop tests. The strapless mount structure reduces photoelectron emission and thus retards sodium diffusion through the light source capsule (10). Elimination of electrically conductive metal straps conventionally used to mount the light source is the main contributor to the improved performance.
