    Abstract: Lamp assemblies for illuminating interior or exterior spaces of a vehicle are provided. In one implementation, a lamp assembly includes a housing having a frame, the housing being adapted to at least partially cover a light device installed within the housing. Light radiating from the light device passes through an opening in the frame. The lamp assembly further includes a lens adapted to be removably connected to the frame of the housing. When connected to the housing, the lens is adapted to refract the light radiating from the light device through the opening in the frame. When the lens is connected to the frame of the housing, a shortest path between the light device and the lens is defined by a z-axis. The lens may include one or more slide components to allow the lens to slide into or onto the frame along an x-axis that is perpendicular to the z-axis.

  • Patent number: 10384142
    Abstract: Embodiments herein use multiple different transmission modes of a line-of-sight (LOS) communication system (e.g., an infrared (IR) or visible light communicate system) to simulate user actions that correspond to different distances—e.g., a melee attack versus a ranged attack. A toy device may include various sensors that detect user motion which is then used to identify a user action. If the user action is a melee attack, then the attack should affect only targets that are close to the toy device. To simulate this difference between user actions, the toy device uses a first LOS transmission mode which may have a limited range to send an instruction to a target device. Conversely, if the user action is a ranged attack, then the toy device uses a second LOS transmission mode which has a greater range than the first LOS transmission mode to send the instruction.

  • 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.

The lens is moveable along the axis, preferably positionable at least at three axial positions. The first such axial position is the distance from the LED light source corresponding to the focal point of the lens. The second axial position is the distance from the gobo corresponding to the focal point of the lens. The third axial position is a distance from the LED light source corresponding to less than the focal point of the lens. In one embodiment, the lighting device includes a recycling collar having a central opening through which the axis extends. In another embodiment, the projection lens is a TIR lens.

  • Patent number: 9028100
    Abstract: The adjustable LED lens has a body having a light incident surface and a light-emitting surface respectively mounted on two opposite sides of the body. The light-emitting surface has a concave tapered surface. The adjustable LED lens is mounted on a holder. A distance between the adjustable LED lens and the holder is changeable. An LED is mounted on the holder, wherein a light generated by the LED passes through the light incident surface and the light-emitting surface of the body. The concave tapered surface of the light-emitting surface increases a light distribution angle to increase an illumination range and decrease a glare. The distance between the adjustable LED lens and the LED is changeable to adjust a light shape as desired.

    Abstract: An electronic lighting device may comprise an enclosure, a flame sheet and an electrically powered driving mechanism. The flame sheet may be movably supported or suspended on the enclosure, and may comprise a first portion which is of a flame-like shape. The first portion may be exposed above the top of the enclosure. Light from a light-emitting element may intersect with the surface of the first portion so that the light projects onto the surface of the first portion. The electrically powered driving mechanism may be disposed adjacent 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.

  • Patent number: 9004729
    Abstract: An internal IR filter assembly for an illuminator has a lamp disposed within a reflector with a face plate. A spring-biased IR filter is shaped as a hollow sleeve telescopically disposed over the lamp. A fixed cylindrical pedestal has one end coupled to the face plate. A sliding cylindrical mount is coupled to the IR filter and telescopically disposed over the fixed pedestal. A gear drive is engaged to a driven gear or hub. A motor is coupled to the gear drive to selectively and reversibly rotate the gear drive. The driven gear is coupled to the sliding cylindrical mount of the IR filter to selectively and reversibly translate the IR filter with respect to the lamp. At least one rod is coupled to the driven gear to prevent the rotation of the driven gear. The rod is slidable within the illuminator but rotationally fixed relative to the illuminator.

    Abstract: A light bulb includes a base, light guide, and light source. The base is configured to mechanically mount the light bulb and receive electrical power. The light guide includes light input regions, at least one of the light input regions associated with an optical modifying characteristic, the light guide configured to propagate light by total internal reflection. The light source is located adjacent the light input regions. The light source and light input regions are variably positionable relative to one another to vary location at which light is incident on the light input regions such that light emitted from the light source is selectively apportioned between the light input regions. A characteristic of the light output from the light bulb is modified based on the optical modifying characteristic of the at least one of the light input regions and the relative positioning of the light source and light input regions.

    Abstract: A luminaire having a tubular body that fits into a ceiling mounted sleeve that allows azimuthal rotation of a light beam. The luminaire features an upright tubular heat sink connected to a fixed base having a downward portion inclined at an angle where an LED chip is affixed. The chip is sandwiched in place by a reflector holder having a rim that centers a rotating reflector that admits light from the LED and forms a beam. The angular inclination of the reflector is additive with the angle of the inclined portion of the base allowing vertical angle adjustment of the beam independently of the azimuthal adjustment.

    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.
