Patent ID: 7329999

Claim:
A lamp lighting circuit for a rare gas fluorescent gas lamp having electrodes, in which at least one of the electrodes is provided on an external surface of a discharge container, and a fluorescent layer is provided inside of the container, and an excimer light generated by discharge is used, the lamp lighting circuit, comprising: an oscillation circuit; a power control circuit having a power control element; a boosting transformer that generates a high voltage applied to the rare gas fluorescent gas lamp according to switching of the power control element, in which the oscillation circuit and the power control circuit are connected to a primary side of the boosting transformer, and the rare gas fluorescent gas lamp is connected to the boosting transformer; wherein the power control element is controlled by the oscillation circuit, and transmits power to a boosting transformer; and an output control circuit that controls lighting of the rare gas fluorescent lamp, wherein the lighting circuit has a malfunction prevention circuit that inactivates lighting operation of the lamp after the power is lit until the output control circuit starts normal operation.
