Abstract

PURPOSE: To reduce the consumed power of a lamp, by decreasing the inside diameter of a luminous tube to reduce the power-factor of the lamp.
CONSTITUTION: The high-voltage mercury lamp has consumped power of 75 to 1000 W and a voltage not higher than 145 V. The inside diameter d (mm) of the tube and the consumped power WL (W) of the lamp are related to each other as d≤18.5W0.15L-30 so that the power-factor of the lamp is reduced. Thus, the consumed power is decreased. As a result, the consumed power can be reduced without replacing the lamp by another one as the existing lighting device is used. The scatter in the luminous intensity due to intermittent lighting and the change in the light color of the lamp are eliminated.
