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 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 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 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.
