LD 10149 SILICON NITRIDE COATINGS IN METAL HALIDE LAMPS TO REDUCE SODIUM LOSS ABSTRACT Metal halide lamps are provided which have better lumen maintenance and concomitant lower operating voltage rise over the life of the lamp when a coating comprising silicon nitride is deposited on one or more metal lamp components of a metal halide lamp or on such components and the arc tube's outer surface. When deposited on the outer surface of the arc tube, silicon nitride acts as a barrier to sodium diffusion, thereby retarding or reducing the loss of sodium from within the are tube. When sodium nitride is deposited on metal lamp components, the coating reduces the emission of photoelectrons from such metal lamp components that are exposed to ultraviolet radiation from the arc tube. A method for reducing sodium loss in metal halide lamp is also provided.
