A device and system for simulating the flicker of candle flame is provided by
the
present invention. A series of independent charging and discharging circuits are
provided that produce power waveforms having duty cycles that vary from a highest
duty cycle to a lowest duty cycle. The power waveforms are provided to a series
of LEDs arranged in a vertical stack. The lowest duty cycle power waveform is provided
to the highest LED in the stack and the highest duty cycle power waveform is provided
to the lowest LED in the stack. An approximately flame shaped housing that is partially
translucent is positioned around the vertical stack of LEDs such that the light
from the LEDs is visible while the LEDs themselves are not. A solar panel and an
associated rechargeable battery are used to power the device.
