Lighting delay-off circuit using thyristors Part 3
Source: InternetPublisher:aytwartoofyoroo Keywords: Thyristor delayed lights off Updated: 2020/07/10
(3) The third circuit of the lighting delay-off circuit using thyristors is shown in Figure 2-45. When turning off the light, turn off the switch SA, apply lloV voltage to both ends of the bulb, and emit dim light. After
a period of delay, the bulb goes out. The delay time is determined by R3 and c1.
