One of the lighting delay-off circuits using 555 time base integrated circuit
. The circuit is shown in Figure 2-46. A delay circuit is composed of a 555 time base integrated circuit
and a resistor and capacitor. When the lamp is not used in this circuit, the transformer
T is still energized and consumes energy. The delay time is determined by Ri and C2.
