A safety starter circuit for a gas discharge lamp includes a series arrangement of a glow switch starter, a resistive element, and a thermally controlled switching element. The thermally controlled switching element is in a heat transfer relationship with the resistive element so that the thermally controlled switching element is effectively heated by heat generated in the resistive element. The thermally controlled switching element is designed to make a transition from a conductive state to a non-conductive state when its temperature exceeds a predetermined cut-off temperature. The thermally controlled switching element is arranged in a gas-tight casing. |
