摘要： A lighting circuit, which is lit with a voltage with a square wave, has a DC booster circuit, a bridge type DC-AC converter and an inductor provided at the subsequent stage of the DC-AC converter. A metal halide lamp is connected in series to the inductor. Another inductor and a capacitor are provided between the DC booster circuit and the DC-AC converter. A series circuit of a resistor and a diode is connected in parallel to the second inductor. This structure generates a resonance voltage having a high peak value to compensate for a re-ignition voltage of a discharge lamp which is produced when the polarity of the square-wave voltage is switched, thereby preventing the lighting failure of the discharge lamp immediately after the lighting starts.

摘要： Disclosed is a lighting circuit for a vehicular discharge lamp, which can accurately and promptly detect an abnormal status to thereby improve the reliability and safety usage. When a lighting switch in the lighting circuit is set on, a batter/voltage is boosted by a DC booster circuit and then converted into an AC voltage by a DC/AC converter before being supplied to a metal halide lamp. When power supply continues with the lamp in an open-circuit state or a short-circuited state, a fire may be set or an electric-shock originated accident may occur. An abnormality detector for detecting an abnormal status is provided to cope with such a problem. The abnormality detector detects the output voltage of the DC/AC converter, very close to the lamp voltage, determines that the lamp in the open-circuit state when the detected level is equal to or above a predetermined value and determines that the lamp in the short-circuited state when the detected level is equal to or below a predetermined value. The abnormality detector sends an abnormality detection signal to apower cutoff relay circuit to open its relay contact on the power line to cut off power supply to the DC booster circuit. The short-circuited state/of the lamp can also be determined by monitoring individual voltages applied to both terminals of the lamp and comparing those voltages with each other.

摘要： Disclosed is a lighting circuit for a vehicular discharge lamp which controls current limitation in accordance with the status of the discharge lamp to thereby suppress an increase in consumption current when a source voltage drops. In the lighting circuit, when a lighting switch 5 is set on, a battery voltage is boosted in a DC booster circuit and is converted into an AC voltage by a DC/AC converter before it is applied to a metal halide lamp. The DC booster circuit has a chopper structure having an inductor and a field effect transistor (FET). A control signal from a control circuit is sent to the FET. The control circuit has a V (voltage)-I (current) controller for controlling the lighting and a PWM (Pulse Width Modulation) controller. The lighting circuit further has a current compensator to prevent an excessive current from flowing through the FET at the beginning of the lighting or when the battery voltage drops. This current compensator monitors the status of the lamp, produces a signal of a sawtooth wave corresponding to this status, and superimposes this signal on a current detection signal, thereby restricting the peak value of the current flowing through the FET and the average current with the help of the slope compensating function of the PWM controller. Thus, current limitation is controlled so that when the lamp current is large, the degree of current limitation is increased.

摘要： Disclosed is a lighting circuit for a vehicular lamp which cuts off power supply to the discharge lamp when the discharge lamp flickers due to the expiration of its service life or the like, thus ensuring safety for an approaching vehicle. In the lighting circuit for a metal halide lamp, when a lighting switch is set on, the battery voltage is boosted by a DC booster circuit and is then converted into an AC voltage by a DC/AC converter. This AC voltage is applied to the metal halide lamp. An abnormality detector is provided to detect that the lamp gets into a flickering state. When the output voltage of the DC booster circuit becomes greater than a threshold value after a predetermined wait time elapses from the point at which the output voltage has exceeded the threshold value, the abnormality detector determines this situation as abnormal lighting and sends a signal to a power cutoff relay circuit to stop supplying the battery voltage to the DC booster circuit.
