Abstract

PURPOSE: To prevent an operation of discharge from being stopped after starting, by forming a bimetal piece of the bimetal switch into specific shape, and arranging an operation of the bimetal switch in such manner with the temperature of closing lowered below that of opening.
CONSTITUTION: A bimetal switch 17 is constructed by a bimetal lead 18, connected to a heating resistor 16, a fixed contact 20, connected to a fixed lead 14 and a bimetal contact 19, and a bimetal piece 21, connected to the bimetal contact and with its another end facing to the bimetal lead 18. The bimetal piece 21, with a length of center portion (b) in the lengthwise direction made longer than a length of both edge portion (a) in the lengthwise direction, is provided with a recessed part in its surface. With this discharge lamp made in conduction, the resistor 16 generates a heat, to make the bimetal piece 21 intending to expand, with the recessed part becoming a convex shape, and the bimetal piece 21 and the lead 18 are opened to induce a high voltage in the stabilizer, and the lamp is started. And then, the bimetal piece 21 is not contacted to the bimetal lead 18 at all immediately after starting by heat radiation of a luminous tube 3, and a going out failure of the discharge lamp can be eliminated.
