摘要
The circuit consists of a power supply switch (2) to switch the alternating current of the circuit according to the control signal of the microcomputer (1), a pulse shaping circuit to transform the driving voltage (+B) of the switch into pulses when the switch is off, and a chroma IC to select R.G.B mode in response to the pulses. The pulse shaping circuit comprises two resistors for dividing the driving voltage (+B) and a capacitor.
