Claim:
1. A system for resembling an open candle flame comprising a holder and a base, said holder comprising a gyro-levitation unit, an optical device, a first light source, a flame display, a weight, and a mechatronics based actuator; said base comprising a second light source, a processor and a power source, wherein said gyro-levitation unit comprises at least one outer gimbal mounted on sidewall of the holder and at least one inner gimbal physically mounted with said optical device to enable orthogonal axis of rotation; one end of said optical device is physically connected with said flame display and another end of said optical device is physically connected with said weight; said mechatronics based actuator is positioned below said weight and at a space between said optical device and said second light source; said first light source is mounted at sidewall of the holder providing sideway illumination to said flame display while said second light source is positioned on said base providing upward illumination through said optical device to said flame display such that intensity of a flame image displayed on said flame display is a combination of said illuminations from the first light source and the second light source; said mechatronics based actuator, said first light source, and said second light source are modulated by Pulse Width Modulation (PWM) signal generated from said processor such that dynamic motion of said mechatronics based actuator aligns with the variation pattern of brightness of the combined illuminations from the first and the second light sources.
