A lighting apparatus has an upper hub, a base, a lower hub, and a pair of illumination devices that are pivotably supported at the upper hub, with each illumination device being pivotable up and down towards each other, as well as being rotatable. A telescoping shaft assembly has an inner shaft and an outer shaft, with the inner shaft telescopically received inside the outer shaft, the inner shaft having an upper end that is secured to the upper hub, and the outer shaft having a lower end that is secured to the base. A plurality of legs are connected to the lower hub and the base for pivoting motion therebetween.

Imitation candle devices and systems with enhanced features enable simulation of a realistic candle flame using multiple angled light sources that illuminate a surface area of a movable imitation flame element in a controlled manner. In some implementations, the imitation candle devices further include a color detection module that adjust the color of the imitation candle device based on a sensed color of the surface a surface that the candle rests upon.

An electric candle device that resembles a real was candle includes an outer shell with an uneven edge around the top of the outer shell. The device includes one or more light emitting elements positioned within a cavity inside the outer shell and that emit beams at a non-zero angle with respect to a longitudinal axis of the electric lighting device to provide illumination from within the cavity in an upward direction and reaching above the top surface after passing through the opening. An optical element is positioned to receive light from the one or more light emitting elements and to direct the received light toward the top surface. The optical element has a focal point to change one or both of a size and direction of the light received prior to projecting the light in the direction of the top surface.

A display article (10) includes a plurality of display areas (12, and 13a to 13c). Display areas adjacent to each other differ in at least one of an average hue, an average brightness and an average chroma and a first object to be displayed (21) is formed by a combination of the plurality of display areas (12, and 13a to 13c). At least one of the display areas (12, 13a to 13c) includes a Fourier transform hologram (20R, 20Y) configured to convert incident ray from a point light source or a laser light source into a second object to be displayed.

A light fixture includes a platform, a trunk support, a light source assembly, and a finial. The trunk support is coupled to and extends upwardly from the platform. The trunk support defines an elongated cavity therein, exterior surfaces facing away from the elongated cavity, and an end opposite the platform. The end defines an opening to the elongated cavity. The light source assembly includes light sources and wiring in electrical communication with the light sources. The light sources are coupled to exterior surfaces of the trunk support, and the wiring extends from the light sources, into the elongated cavity, and out the opening in the end of the trunk support. The finial caps the top end of the trunk support. The finial is coupled with the wiring extending out the opening in the end of trunk support to maintain electrical continuity with the light source assembly.

Described are systems and methods for providing improved indoor reception of OTA (Over-the-Air) broadcast signals. The systems described include antenna systems with one or more network interfaces for providing a transport stream received by an antenna to a network.

Methods, systems and devices associated with an electronic candle are disclosed. In one example aspect, an electronic candle includes a mounting frame that includes a first connector and a power supply assembly that is detachable from the mounting frame. The power supply assembly includes a second connector that forms a coupling mechanism with the first connector. The power supply assembly further includes an energy storage, a first power source configured to charge the energy storage, and an electrical connection interface configured to connect the power supply assembly to a second power source. The electronic candle also includes a light-emitting assembly that is removably coupled to the mounting frame configured to operate using power provided by the power supply assembly, and one or more controllers configured to control an operation of the light-emitting assembly.

According to embodiments of the present invention, a flameless candle is claimed, depicted, and described. The candle has a hollow interior region, an inner surface having an radius, and an outer surface having an outer radius. The candle also has a riser located within the hollow interior region. A lamp (e.g., LED) is also located in the interior region and above the riser. A light shield is located within the hollow interior region. The light shield is below the lamp and has an outer bound with a radius. The light shield also has a sloped portion. The light shield may have a reflector. The radius of the outer bound of the light shield is less than the radius of the inner surface of the candle shell. The sloped portion of the light shield slopes downwardly towards the outer bound.

A luminaire includes a housing, a downlight that includes one or more first light sources configured to emit a first light downwardly from the housing, a waveguide, and one or more second light sources. The waveguide is formed of a portion of an optical material and characterized by opposing planar faces joined by one or more edge faces about a periphery of the optical material. The waveguide forms at least a portion of an uppermost optical surface of the luminaire. The one or more second light sources are coupled with the housing and configured to emit a second light into the optical material through at least one of the one or more edge faces. The waveguide is configured to emit at least a portion of the second light upwardly from an upper one of the planar faces.

A table lamp has a lighting head with an asymmetrical light output. The lighting head is reversibly mountable to a support structure, so that the light output can be adapted to be optimised for positioning on either side (left or right) of a table.
