Use color-changing light-emitting diodes as fuse indicator circuits
Source: InternetPublisher:石榴姐 Updated: 2015/12/10
Shown in the figure is a fuse indicator circuit used in a single-phase AC circuit. The LED in the picture is a color-changing light-emitting diode. When the fuse FU is normal, both light-emitting diodes in the LED light up in orange; once the fuse in the fuse blows, the right one of the two-color light-emitting diodes loses power and does not light up, and only the left one Still lit in red.
