の光導電素子と、該第1の光導電素子によりオン・オフ
されるスイッチング回路と、該スイッチング回路のオン
時間設定用のコンデンサと、前記スイッチング回路によ
ってトリガされるトライアックと、前記第2の光導電素
子によりトリガされるSCRと、前記トライアック又は
SCRがオン状態にある時点灯する電球よりなり、瞬時
に暗くなる場合に一定時間だけ点灯させると共に、徐々
に暗くなる場合或いは前記時間経過後は前記照明の半分
の明るさで再び明るくなるまで点灯させる様にしたこと
を特徴とする照明回路。1st and 2nd whose resistance value changes depending on the intensity of light with the power supply section
a photoconductive element, a switching circuit that is turned on and off by the first photoconductive element, a capacitor for setting the on-time of the switching circuit, a triac triggered by the switching circuit, and the second photoconductive element. It consists of an SCR triggered by a conductive element, and a light bulb that lights up when the triac or SCR is in the on state, and it lights up for a certain period of time when it gets dark instantly, and when it gets dark gradually or after the above-mentioned time has elapsed. A lighting circuit characterized in that the lighting is turned on at half the brightness of the lighting until it becomes bright again.
