WAVE-DRIVEN ELECTRONIC CANDLE

A wave-driven electronic candle includes an illuminator, a power supply for providing the necessary working voltage, a signal receiver, and a controller including a signal amplifier for amplifying a wave signal received by the signal receiver, a signal regulator for selecting a series or part of the waveform from the signal amplified by the signal amplifier, a filter for removing noises from the selected waveform, and an output amplifier for amplifying the filtered waveform signal for output to the illuminator to control the illuminator to flash.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1shows a wave-driven electronic candle in accordance with the present invention. The wave-driven electronic candle2comprises an illuminator29formed of LEDs (light-emitting diodes), a power supply25electrically connected to the illuminator29to provide the illuminator29with the necessary working voltage, a signal receiver26that can be a sound receiver (microphone)27for converting a sound signal into an electrical signal and/or a radio signal receiver28for converting a radio signal into an electrical signal and is electrically connected to the power supply25to obtain the necessary working voltage, and a controller20electrically connected in series between the signal receiver26and the illuminator29for controlling the illuminator29to flash according to the sound signal or radio signal received by the signal receiver26. The controller20is also electrically connected to the power supply25to obtain the necessary working voltage. Further, the controller20comprises an input amplifier21electrically connected to the signal receiver26for receiving a wave signal from the signal receiver26and amplifying the wave signal, a signal regulator22electrically connected to the input amplifier21for picking up a series or part of a waveform from the wave signal outputted by the input amplifier21, a filter23electrically connected to the signal regulator22for filtering the amplitude and/or wavelength and/or frequency of the waveform outputted by the signal regulator22, and an output amplifier24electrically connected in series between the filter23and the illuminator29and adapted for amplifying the filtered waveform signal outputted by the filter23and outputting the amplified waveform signal to the illuminator29, driving the illuminator29to flash.

In conclusion, the invention picks up a surrounding sound wave or radio wave signal and processes the signal for controlling an illuminator to flash. The design of the wave-driven electronic candle in accordance with the present invention is more practical and more attractive and less tedious to the eyes.
