Abstract

PURPOSE: To make the promotion of highly prolonging a life of the lamp, with a start efficiency heightened as well of discharge, by providing a starter, where an angle made between the direction of one contact of the thermal switch opening and closing and the contact plane of another contact is made below a specific angle.
CONSTITUTION: A contact 12a of a bimetal 13 is made of round rod material, and protruding in perpendicular to the direction the bimetal 13 moves. And a contact 12b of a fixed contact plate 14 is made of round rod material folded into V-letter shape, and arranged in the direction of perpendicularly intersecting with the contact 12a in an attitude with the contact 12a put between. That is, an angle θ1, θ2 made by the direction of the contact 12a switching and the contact plane U1, U2 of the two contacts X, Y of the contact 12b is less than 30 deg. In such constitution of the thermal switch, a speed of the bimetal becomes faster, and a discharge lamp of long life can be provided without cansing a welding of the contact.
