  • Patent number: 10030831
    Abstract: A flame simulator can include a light beam source, a range limiter, a light beam mover, a power supply, a power control circuit, and a flame screen. The light beam source can be adapted to project a movable beam of light with a circular, oval, elliptical, or otherwise round, cross-sectional shape and with an intensity, shape and/or color that mimics a flame (e.g., a candle flame) when the beam strikes the flame screen. The light beam mover can generate beam movement and the range limiter can limit the range of movement so that the beam stays mostly on the flame screen in a region bounded by the typical range of movement of a flame being simulated (e.g., a candle flame moving in response to ambient air currents). The light beam mover can cause the illumination provided by the beam to dance on the flame screen with variations in position and shape that mimic a dancing flame (e.g., a candle flame being blown about by air currents). One or more of the flame simulators can be incorporated into an imitation candle.

  • Patent number: 8974075
    Abstract: A flashlight has a casing having a front end, a light source axially secured in the housing inward of the front end, and a two-part connecting sleeve forward of the light source and having a rear part secured in the housing and a front part. Interengaging formations couple the parts together for only limited axial movement relative to each other, but lock them rotationally and prevent axial separation beyond a predetermined limit. A lens is mounted in the front part. A head sleeve secured to the front part extends axially rearward over the front end of the casing so that relative axial movement of the front and rear parts axially shifts the lens relative to the source.

  • Patent number: 8960961
    Abstract: A lamp with functions of adjusting an illumination direction is disclosed. A substrate is disposed on a base and includes a through groove. At least one light source is disposed on the substrate. An electronic control unit is disposed in the base. A telescopic member is disposed in the base and is connected to the electronic control unit. The electronic control unit drives the telescopic member to elongate and shorten. A flexible light guiding sheet is connected to the telescopic member. When the electronic control unit drives the telescopic member to elongate, the flexible light guiding sheet protrudes onto the substrate via the through groove of the substrate and deflects toward a specific direction, changing the illumination direction of the light source.

  • Patent number: 8926137
    Abstract: An electronic lighting device may comprise an enclosure, a light-emitting element, a flame sheet and a swing mechanism. The flame sheet is movably supported or suspended on the enclosure, and may comprise an upper sheet which is of a flame-like shape. The upper sheet is configured to be exposed above the top of the enclosure. Light from the light-emitting element intersects with the surface of the upper sheet so that the light projects onto the surface of the upper sheet. The swing mechanism is disposed beneath the flame sheet and can apply a force on the flame sheet to actuate the flame sheet to sway or swing. By the present application, a visual experience of true fire can be achieved and an interestedness and appreciation can be improved. A method for manufacturing the same is disclosed.
