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 vehicular discharge lamp for lighting a discharge lamp using a DC power supply, comprises an OFF state detector, a DC input voltage detector and a power cutoff means. The OFF state detector detects an OFF status of a discharge lamp. The DC input voltage detector detects if a DC input voltage is within a predetermined range. The power cutoff means inhibits power supply to the discharge lamp when the OFF status of the discharge lamp is detected by the OFF state detector and the DC input voltage lying off the predetermined range is detected by the DC input voltage detector, and permits power supply to the discharge lamp upon reception of a signal indicating that the DC input voltage has returned within that range.

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.

摘要： A vehicle light apparatus 1 includes a discharge lamp 7 as a dipped (low)-beam light source and a high-beam light source or a light source of an auxiliary light (incandescent lamp) 3 as a substitutional light source of the discharge lamp. If the apparatus detects an input voltage from a power supply becoming equal to or greater than a threshold value in a state that only the discharge lamp is lit, the incandescent lamp is automatically lit on. To use the high-beam light source in place of the discharge lamp, light extinction lighting is performed or the light application direction is directed downward from the horizontal direction.

摘要： A hybrid IC of electronic circuit for a discharge lamp is disposed on the bottom of a metal case. A transformer, an inductor, a transformer, and a capacitor are disposed in a resin case. The resin case is contained in a metal case. In this instance, the transformer, the inductor, the transformer, and the capacitor are located outside the outer periphery of the IC so that the IC does not overlap on the transformer and other components. The transformer for a starter circuit has a secondary winding the inductance of which is 2.5 mH or larger, and a capacitance of a smoothing capacitor of a DC—DC converter is 0.5 &mgr;F or smaller. The switching frequency f of a MOS transistor is selected so that L2×C1 is equal to or larger than 1×10−1×f−1.68.
