Abstract
PURPOSE: To provide a switching circuit for lighting apparatus, highly reliable, durable, promptly responsible and easy to adjust intensity of lighting, in which on-off control of an semi-conductor switching element is achieved in relation with on-off operation of a heat-sensitive thyristor that is thermally connected with a heater generating a quantity of heat related with the output of means for detecting intensity of light.
