Abstract

PURPOSE: To reduce the change of characteristic due to the change of lighting angle, by properly regulating the amount of mercury encapsulated in the light emitting tube and the ratio of scandium atom in scandium halide and sodium atom in sodium halide against said mercury.
CONSTITUTION: Scandium halide and sodium halide are encapsulated together with rear gas and mercury in light emitting tube 1, where the amount of encapsulated mercury per 1cc of inner volume of light emitting tube is made more than 2.8mg, while the atomic ratio of scandium atom in scandium halide against the mercury is made to be 0.005W0.11 and the atom ratio of sodium atom in sodium halide against the mercury is made to be 0.61W2.0.
