  • Patent number: 11009195
    Abstract: An apparatus for simulating an open candle flame having a swing holder located within a casing and engaging with a connecting rod, the connecting rod pivotally and rotatably connecting to the swing holder to form a first pivot structure for allowing the connecting rod to turn about a first axis, the swing holder pivotally and rotatably connecting to the casing to form a second pivot structure for allowing the swing holder and the connecting rod to turn about a second axis. The swinging mechanism of the apparatus is able to minimize the cost and the number of parts, ease and simplify assembly, and insure the flame display stays in place after manufacturing and during transit and handling.

  • Patent number: 9958123
    Abstract: 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.
