摘要： A lighting circuit for a vehicular discharge lamp has a DC voltage booster circuit, a control circuit, and a voltage drop detector. The booster circuit boosts an input voltage from a DC voltage input terminal to provide an output voltage to be applied to the discharge lamp. The control circuit functions for varying the output voltage of the DC booster circuit to effect lighting control including constant power control of the discharge lamp. The voltage drop detector detects a DC input voltage applied to the booster circuit. In response to a signal received from the voltage drop detector in accordance with a drop of the DC input voltage, the control circuit performs voltage boosting control to set power supplied to the dicharge lamp lower than the rated power. It is therefore possible to suppress an increase in current consumption and a consequent increase in generated heat when the DC input voltage drops. Further, the lighting circuit for a vehicular discharge lamp has a protection circuit which cuts off the supply of the DC input voltage to the DC voltage booster circuit when it is detected that the DC input voltage has dropped too low to maintain the lighting of the discharge lamp, and allows the DC input voltage to be supplied again to the booster circuit when the DC input voltage has been restored to or greater than a predetermined value. It is therefore possible to prevent the circuit elements from being deteriorated or destroyed due to an abnormal reduction in DC input voltage.

摘要： A lighting circuit for a metallic halide lamp for vehicular headlight applications is disclosed. Included are a pair of input terminals between which a battery is connected for feeding the lamp via a normally open relay switch which is closed upon energization of an associated relay coil. The relay coil is connected in series with an operator actuated lamp switch and a protection switch, so that both lamp switch and protection switch must be closed to energize the relay coil and hence to close the relay switch. The protection switch is automatically opened to deenergize the relay coil when the battery develops overvoltage or when the lamp will not glow upon closure of the lamp switch. In an alternate embodiment, the protection switch is also opened in response to the development of overcurrent or overvoltage by a d.c. voltage booster circuit included in the lighting circuit.

The booster circuit boosts the input voltage from a DC voltage input terminal to provide an output voltage that is converted into an AC voltage to be applied to a high-pressure discharge lamp. The voltage detector detects the output voltage of the booster circuit. The current detector detects an output current of the booster circuit. The control circuit applies a control signal corresponding to signals from the voltage detector and the current detector to control the output voltage of the booster circuit. The control circuit, the voltage detector and the current detector constitute a feedback system for the booster circuit.
