Incandescent lamp step-down circuit
Source: InternetPublisher:桂花蒸 Keywords: incandescent lamp buck circuit diode Updated: 2020/12/23
Adding a diode or capacitor to the circuit uses the unidirectional conductivity of the diode to allow only half a cycle of alternating current to pass through, thus saving electrical energy.
Capacitors are not energy-consuming components, but they have a voltage-reducing effect, which can reduce the power of incandescent lamps with tens of watts to a few watts.
