Abstract

See full text

A system simulating an open candle flame is provided in the present invention. In a preferred embodiment, the present system comprises a gyro-levitation unit including two spinning wheels with axes mutually perpendicular to each other to allow a two-degree of rotational freedom resembling the open candle flame motion caused by air flow in its surrounding environment. A mechatronics based actuator made of a bi-metal is employed to disturb the equilibrium of the gyroscope by exerting an actuating force against the gyro-levitation unit. Electric current controlled by a dedicated electronic unit flowing through the actuator allows reciprocal linear motion aligned with the visible light pattern of the candle flame. Varying light intensity of the candle flame is obtained as a combination of two light sources with one transmitted to a flame display through an optical device by total internal reflection and another one by projecting on its sideway.
