The Design of Adaptive Ambient Noise Sound and Light Controlled LED Lamp Based on Integral Mode V-PWM Converter

In this paper adaptive ambient noise sound and light controlled LED lamp based on integral mode V-PWM converter is proposed. This converter can complete the integral way of weak voltage amplification and pulse width modulation at the same time, it has the characteristics of good performance of anti-interference, high magnification, high conversion accuracy, simple circuit etc. Adaptive ambient noise sound and light controlled LED lamp is designed using this converter. This LED lamp can work in various occasions with high noise, such as toilet assembling with fan, corridor etc. It has stable work, simple circuit and low cost.
