Abstract

PURPOSE: To provide a less power consumption, simultaneously with a stabilized lamp characteristic obtained, by means of specifying leading particulars of the luminous tube.
CONSTITUTION: With a lighting made by a 300W lag-phased stabilizer, and the dimension of a luminous tube 1 made to dcm for inside diameter, lacm for distance between electrodes, and lccm for distance from the point end of electrode to the end sealed part, if assumed α for the lamp power lowering factor when lighted by the 300W lag-phased stabilizer, the lamp is made into a shape to meet a condition of 1.5≤d≤1.9, 5≤300(1-α)/(πdla+4πlc 2)≤10, 0.1≤ 4πlc 2/(πdla+4πlc 2)≤0.5, 0.1≤lc/la≤ 0.4.
