Abstract

PURPOSE:To raise a lamp voltage in a simple constitution, by providing a metallic plate concentrically with an electrode conductor at the end face of an end cap. CONSTITUTION:The end part of a luminous tube 3 is air-tightly sealed by an end cap 8 through which an electrode conductor 11 is extensibly provided. A metallic plate 9 is concentrically provided almost being closely attached to the end face of said end cap 8. Then the heat of a lamp during its lighting is accumulated in and reflected from the metallic plate 9 to raise the coldest point temperature of the luminous tube 3 and a voltage of the lamp.
