Abstract

PURPOSE: To improve the efficiency of lights, by increasing the rate of thallium iodide to indium iodide in weight ratios when horizontally lighting this lamp after enclosing sodium iodide, thallium iodide and indium iodide.
CONSTITUTION: A fixed quantity of mercury, rare gases for starting, NaI, TlI and InI are enclosed in a luminous tube bulb 1, to which internal both ends main electrodes 2, 2 are arranged. In this case, the weight ratios of TlI to InI are regulated in 5W10, and the quantity of InI enclosed is controlled in 0.02W0.05mg/cc. Thus, the efficiency of lights can be improved.
