摘要： Disclosed herein is a discharge lamp lighting device which realizes the minute control of the lighting sequence and electric power of a high-pressure discharge lamp and the control of various anti-error protecting functions by mounting a microcomputer. However, since microcomputer processing typically progresses in accordance with the programs previously recorded on a ROM, various actions of the discharge lamp are controlled in accordance with ROM-recorded data settings. To modify these settings, the contents of the ROM need to be updated. Therefore, a function for communicating with an external device is assigned to the microcomputer so that various data settings can be modified.

摘要： In a discharge lamp apparatus, a metal case has a blind-end box-like configuration, and a ceramic board and a power MOS transistor of a DC/DC converter are mounted on an internal bottom surface of the metal case while a printed circuit board is mounted on an opening side of the metal case in a state separated from the power MOS transistor and the ceramic board in a thickness direction of the discharge lamp apparatus. On the ceramic board, there are mounted a discharge lamp control circuit for controlling power to a discharge lamp by switching the power MOS transistor and an H bridge circuit for forming a voltage to be applied to the discharge lamp into a pulse shape, and on the printed circuit board, there are mounted a high-tension coil for generating a voltage to be applied to the discharge lamp, and others. With this construction, the heat developed in the discharge lamp control circuit, the H bridge circuit and the power MOS transistor conducts efficiently to the metal case.

摘要： The discharge lamp lighting circuit is structured such that positive and negative polarity voltages separately generated from two output terminals of a DC power source circuit are sent to the DC-AC conversion circuit 4. To switch these output voltage, a plurality of switch elements provided in a DC-AC conversion circuit are alternately operated by drive circuits. The resultant AC voltage is supplied to the discharge lamp. A current detection element is provided in the DC power source circuit, and the signal from the element is received by the current detection circuit to conduct current detection.

摘要： An electronic ballast for a high intensity discharge lamp combines the functions of a boost converter and a buck converter and combines the line voltage rectification with the load commutation. With such a configuration, only one controller is required, and the control signal for the controller is taken off a resistor in series with the bus capacitor. As such, the lamp power is indirectly controlled by regulating the input buck current to the buck converter portion, instead of by measuring the lamp current.
摘要翻译：用于高强度放电灯的电子镇流器结合了升压转换器和降压转换器的功能，并将线路电压整流与负载换向相结合。通过这样的配置，仅需要一个控制器，并且控制器的控制信号与总线电容器串联一个电阻器。因此，通过调节到降压转换器部分的输入降压电流而不是通过测量灯电流来间接地控制灯功率。
