摘要
Mercury metal-halide HID lamp has as a discharge-sustaining filling mercury, neodymium iodide and cesium iodide, with the gram mol ratio of neodymium iodide to cesium iodide being about 1:1. Sodium iodide may also be included as a discharge-sustaining material to supplement the foregoing materials. The lamp has a protective outer envelope which carries on the inner surface thereof finely divided phosphor which specifically is calcium sulfide activated by europium and sensitized by one of lead or tin, in order to lower the color temperature of the lamp and improve the color rendering properties thereof.
