ABSTRACT:
A primary color lamp comprises a glass envelope with a krypton arc doped with metal halides. A cesium bromide or cesium iodide solution is included with lithium iodide (LiI) to produce red light, thallium iodide (TlI) to produce green light and indium iodide (InI) to produce blue light. The solution controls the vapor pressures of the lithium iodide (LiI), thallium iodide (TlI) and indium iodide (InI) and allows them to be balanced for light amplitude output. No mercury is used in order to eliminate a corresponding yellow light output and the filter complications that result in a system that operates on the primary colors.
