Abstract

PURPOSE:To grasp the life of a discharge lamp proir to lighting-up and prevent overload on a high-frequency light-up circuit by sensing temp. rise of discharge lamp electrodes or the high-frequency lightup circuit, and thereby controlling this lightup circuit. CONSTITUTION:A fluorescent lamp 1 consists of a glass bulb 2, in which four parallelly arranged vertical pipes are in communication with three horizontal pipes, and a base thereto 3. Four lamp connection pins 4 are installed at the end of this base 3, while two bosses for hooking 5 at the side face of the base 3. High-voltage pulses impressed between the drain and source of a transistor Q1 are consumed by a surging absorber SZ1 to generate heat, that is sensed by a thermistor TH1, and when heat emission of the SZ1 exceeds a certain level of temp., a high-frequency lightup circuit consisting of Q1, oscillator IC1, SZ1, etc., is broken.
