Color light chain circuit with adjustable brightness and conversion frequency
Source: InternetPublisher:司马缸砸光 Keywords: Colored lights adjustable frequency triode Updated: 2021/06/23
It consists of transistors VTi ~ VT3, etc. to form a three-level multivibrator. The light emitted by the lanterns
does not flicker, but changes rapidly and smoothly, thus producing an interesting luminous effect. The frequency of brightness changes of the colored lights can
be adjusted by the potentiometer RP. If the power of each group of colored lights is 300W, choose KP5A/500V for thyristors vl~V3, and
ZP5A/500V for diodes VDi-VD4.
