一符号を付して重複する説明を省略する。1 is a circuit configuration diagram showing a first embodiment of the present invention. The configuration different from FIG. 6 shown in the above-mentioned conventional example is that a passing means B formed by a switch control section 5 and a dimming control section 6 is configured. In addition, the same portions are denoted by the same reference numerals and redundant description will be omitted.

[When a (PS, ON) H-level signal is received] When this passing signal is received, the power switch SW is turned on by the action of the switch controller 5. Then, a high-frequency voltage is generated at the output of the lighting circuit unit A, and a high-voltage pulse voltage is further generated at the output end of the igniter unit 3, and the discharge lamp La reaches the rated light output lighting (100%). [When (PS, OFF) L Level Signal is Received] Next, when the passing signal is received, the switch control unit 5 maintains the power switch SW in the ON state. Then, the high frequency output of the lighting circuit section A is controlled by the control section 4 in the decreasing direction by the output signal of the dimming control section 6, and the discharge lamp L
The light output of a is dimmed.

Even if the H level or L level signal of S) is not continuously received, the dimming state is continued.

され、放電灯Ｌａが定格光出力点灯（100%）する。Then, after a lapse of a predetermined period (T2), the power supply switch SW is cut off by the action of the switch control section 5, and the discharge lamp La is turned off. Here, it is not always necessary to completely cut off the DC power supply B, and it suffices to substantially cut off the power switch SW to the extent that the discharge lamp La is turned off. Further, the output of the lighting circuit unit A may be substantially reduced to the extent that the discharge lamp is turned off. [When (PS, OFF) L level signal is received and (PS, ON) H level signal is received within a predetermined period (T2)] In this case, the dimming control state of the dimming control unit 6 is reset. Then, the discharge lamp La lights up at the rated light output (100%).

と調光点灯を繰り返すことになる。On the basis of the above-mentioned operation state, in the case of passing, the above-mentioned states are alternately repeated so that the discharge lamp La is turned on at the rated light output (100%).
And the dimming lighting will be repeated.

とができる。Therefore, since the high voltage pulse voltage is generated by the igniter section 3 only once in the above-mentioned state, the adverse effect on the life of the discharge lamp La is reduced and at the same time,
Generation of noise due to generation of high-voltage pulse voltage can also be suppressed.

Needless to say, it is only necessary to be able to change the effective value of the high frequency voltage.

変化して視覚にて認識できれればよい。In this embodiment, the case where the light output is dimmed has been described, but conversely, the case of high output lighting in which the light output is increased and the case of rated light output lighting (100%) are used. It may be passing by alternating repetition. The point is that the light output changes and can be visually recognized.

In this case, even if the L signal in the OFF state and the H signal in the ON state of the passing signal, which changes in a short time, are received, the lighting time of the discharge lamp La can be secured so that the light output can be visually recognized by human eyes. Because it is done, the utility value is high.

The configuration different from that of the first embodiment is configured such that all the passing signals (PS) are input to the dimming control unit 6 and the switch control unit 5 receives the signals from the dimming control unit 6. That is the point. Therefore, it is possible to reduce the number of times signals are generated by the switch control unit 5 and the time.

The configuration different from the first embodiment described above is an example of the passing means during the nighttime traveling in which the headlight is already turned on, and the switch control unit 5 is unnecessary.

Light control), the discharge lamp La is set to a predetermined lighting state (light output dimming) in the case of the next L level signal reception, and a predetermined lighting state is set in the next H signal reception. The output is increased from the lighting state (rated light output lighting (100%)) and the passing signal (PS)
The light output in the lighting state of the discharge lamp La is alternately increased and decreased according to the alternating repetition of the H level and L level signals.
