HIGH-INTENSITY-DISCHARGE LAMPS
HIGH-INTENSITY-DISCHARGE LAMPS112. High-intensity discharge lighting‚ÄÉcovers (Standard Handbook for Electrical Engineers) a general group of lamps consisting of mercury, metal halide, and high-pressure sodium lamps. A mercury lamp is an electric discharge lamp in which the major portion of the radiation is produced by the excitation of mercury atoms. A metal halide lamp is an electric discharge lamp in which the light is produced by the radiation from an excited mixture of a metallic vapor (mercury) and the products of the dissociation of halides (e.g., halides of thallium, indium, sodium). A high-pressure sodium lamp is an electric discharge lamp in which the radiation is produced by the excitation of sodium vapor in which…
