Sound-light controlled LED lamp circuit

Abstract

The invention provides a sound-light controlled LED lamp circuit for simulating electronic technology practice teaching. The sound-light controlled LED lamp circuit comprises a sound voltage conversion unit, an alternating voltage amplification unit, a voltage-multiplying detection unit, a light voltage conversion unit, a voltage comparator unit, a timer unit, and an LED drive unit. The alternating voltage amplification unit and the LED drive unit are constructed with triodes, the voltage-multiplying detection unit is constructed with diodes, and the voltage comparator unit and the timer unit are constructed with integrated operational amplifiers. Through intuitive demonstration by the functional circuit, the originally boring verification experiment of an independent unit circuit becomes more vivid. Therefore, the interest of students in participating in the experiment is increased, the effect of experimental teaching is enhanced, and students can have a better understanding of the unit circuit composed of the diodes, the transistors and the integrated operational amplifiers.

Description
