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 the lighting made by a 1000W lag-phased stabilizer, and the dimension of a luminous tube 1 made to dcm for inside diameter of the luminous tube 1, lacm for distance between electrodes and lccm for distance from the point end of electrode to the end sealed part, and if assumed α for the lamp power lowering factor when lighted by the 1000W lag-phased stabilizer, a shape of the tube is made to meet the condition of 2.4≤d≤3.0, 5≤1000(1-α)/(πdla+4πlc 2)≤10, 0.1≤4πlc 2/(πdla+4πlc 2)≤0.5, 0.1≤lc/la ≤0.4.
