摘要： A lighting circuit converts the output voltage of a DC booster circuit to an AC voltage which is in turn supplied to a discharge lamp connected between AC output terminals. The lighting circuit comprises a short-circuit detector for detecting a change of a DC voltage from the DC booster circuit to a square-wave voltage when short-circuiting between one of the AC output terminals and ground occurs, and sends a detection signal via a hold circuit to a power cutoff relay circuit. As a result, a relay contact in the power cutoff relay circuit is opened to inhibit the operation of the lighting circuit.

摘要： A lighting circuit for a discharge lamp includes lighting control circuit for controlling the lighting of a discharge lamp, ignition means for supplying a trigger pulse to the discharge lamp and a socket. Power is supplied to the discharge lamp via terminals of the socket and terminals of a connector section of the discharge lamp. The socket and the connector section are respectively provided with connection terminals which are to be connected together while the discharge lamp is connected to the connecting member. When those connection terminals are not connected together, the supply of power and the supply of the trigger pulse to the discharge lamp are inhibited. This prevents problems (damaging insulation, an electric shock and the like) from arising when the lighting circuit is activated while the discharge lamp is not connected to the lighting circuit.

摘要： In a lighting circuit, a battery voltage is supplied via a DC booster circuit to a DC-AC converter where the voltage is converted to an AC voltage with a rectangular waveform. This AC voltage is supplied to a discharge lamp. At this time, the DC-AC converter controls the frequency of the rectangular wave output from the DC-AC converter in accordance with a signal sent to a bridge type driver from a frequency controller. A lighting detector is provided to detect if the discharge lamp has been lighted. Upon reception of a signal from the lighting detector, the frequency controller sets the frequency of the output voltage of the DC-AC converter in the pre-lighting period of the discharge lamp higher than the frequency of the output voltage of the DC-AC converter after the lighting of the discharge lamp and restricts the inversion of the polarity of the output voltage of the DC-AC converter until a predetermined time passes sfrom the point of the activation of the discharge lamp.

摘要： A discharge lamp lighting circuit which, in turning on a discharge lamp, when an abnormal condition occurs in a discharge lamp or in the present discharge lamp lighting circuit due to a transient cause, can resume the power supply to the discharge lamp at the time when the present transient abnormal condition cause disappears. The discharge lamp lighting circuit includes lighting control for controlling the lighting of a discharge lamp, an abnormal condition detector for detecting an abnormal condition occurring in the discharge lamp or in the discharge lamp lighting circuit, and a protection circuit which receives a signal from the abnormal condition detector to thereby stop the power supply to the discharge lamp. The protection circuit is composed of first protection unit and second protection unit. When a permanent abnormal condition is detected in the discharge lamp or in the discharge lamp lighting circuit, the power supply to the discharge lamp is cut off by the first protection unit and such cutoff condition of the power supply is also held. Also, when a transient abnormal condition is detected in the discharge lamp or in the discharge lamp lighting circuit, the power supply to the discharge lamp is cut off by the second protection unit and, after then, when the present abnormal condition is no longer detected, the power supply cutoff condition is removed to thereby resume the power supply to the discharge lamp. Further, while the power supply to the discharge lamp is being cut off by the second protection unit, the operation of the first protection unit is prevented from cutting off the power supply to the discharge lamp and holding such power supply cutoff condition.
