摘要： A lighting circuit for a discharge lamp incorporates a DC-DC converter for converting DC voltage and a control circuit for controlling the output voltage from the converter by controlling the ON/OFF operation of an FET which is configured as the converter. The electric current which flows in the FET is monitored by detecting the voltage between the drain and the source to turn the field effect transistor off when the voltage level is at the reference value or higher. Thus, a pulse-by-pulse current limitation is performed. Limitation of an electric current in a switching device in a DC-DC converter of a lighting circuit for a discharge lamp is achieved while reducing the size and cost of the circuit apparatus.

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.

When the power supply control receives from the connecting condition detector a signal indicating that the discharge lamp is removed from the connecting member and also receives from the lighting condition detector a signal indicating that the discharge lamp is in the unlighted condition, the power supply to the discharge lamp is stopped.

摘要： A lighting circuit for a discharge lamp comprises abnormality detection means for detecting an input voltage and/or an input current to be input to a lighting circuit from a power supply and stopping power supply to a discharge lamp when detecting an abnormality in the value of the input voltage and/or the value of the input current.

When the state where the value of the input voltage and/or the value of the input current is equal to or smaller than the first reference value or the first reference range continues for a predetermined time or longer, the abnormality detection means stops power supply to the discharge lamp. When the state where the value of the input voltage and/or the value of the input current is equal to or greater than the second reference value or the second reference range continues for a predetermined time or longer, the abnormality detection means permits power supply to the discharge lamp.

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.
