Abstract:
1. An electronic candle, comprising: a power source; a first circuit assembly electrically coupled to said power source, said first circuit assembly comprising a first waveform generator controllable to generate a first waveform, a first pulse wave generator controllable to generate a first pulse-width modulation signal, a first wave mixer electrically coupled with said first waveform generator and said first pulse wave generator and adapted for mixing said first waveform and said first pulse-width modulation signal, a first drive circuit electrically connected to said first wave mixer, and a first light-emitting diode electrically connected to said first drive circuit and drivable by said first drive circuit to emit light in a first lighting mode; and a second circuit assembly electrically coupled to said power source in parallel with said first circuit assembly, said second circuit assembly comprising a second waveform generator controllable to generate a second waveform, a second pulse wave generator controllable to generate a second pulse-width modulation signal, a second wave mixer electrically coupled with said second waveform generator and said second pulse wave generator and adapted for mixing said second waveform and said second pulse-width modulation signal, a second drive circuit electrically connected to said second wave mixer, and a second light-emitting diode electrically connected to said second drive circuit and drivable by said second drive circuit to emit light in a second lighting mode.
