Pulse small light bulb power saving indicator light
Source: InternetPublisher:子丑寅卯 Keywords: indicator light pulse power saving small light bulb Updated: 2020/04/26
The circuit of the pulse-type small bulb power-saving indicator
light is as shown in the figure. The difference between this circuit and Figure 18-3 is that transistors VTi and VTz are used instead of single-junction transistors
, and a small bulb H is used instead of a light-emitting diode. The pulse width and the interval between pulses
are determined by the values of capacitor C and resistors Ri and R2.
