Abstract
PURPOSE: To improve efficiency and color rendition of a luminous tube without increasing load of the tube wall, by charging prescribed molar ration of aluminum metal with neodymium metal.
CONSTITUTION: Nd and Al are contained in molar ratio of 1:5W5:1 with a starting rare gas, mercury, and one or more of iodine, bromine, and chlorine in a tube, where amount of Nd charged in the luminous tube is 0.01W3mg/cc in the volume of the tube. One or more of Na, Ca, Cs, K, Li, Tl, In, Sc, Sn, Th, and rare earth elements is included in the luminous tube if required.
