ABSTRACT:
A portable electronic light providing a light resembling a candle that can be turned off by blowing on the light or by generating other predetermined sounds. The electronic light comprises a sound sensor, one or more light emitting diodes, or LEDs, a light cover, a housing, and a circuit board. The circuit board includes an amplifier/demodulator circuit, a counter/oscillator circuit, a driver circuit, and a switching circuit. The sensor detects a low frequency created by blowing on the candle type light or other signal, in order to control the power circuit and turn off the light. The counter/oscillator circuit and the switching circuit cause the LEDs to turn on and off, simulating the flickering of a candle.
