To improve design of a lighting device. A lighting device includes optically transparent glass plates provided on side faces and placed on an optical path of light emitted from a light source, where some or all of the optically transparent glass plates contain an optically transparent battery adapted to drive the light source; and an optically transparent glass plate that contains a transparent conductive film by being provided on a bottom face, wherein the optically transparent battery is placed in contact with a pair of transparent conductive film layers, which are connected to the light source. The pair of transparent conductive film layers are formed in a pair of parallel linear grooves formed in a surface of the optically transparent glass plate on the bottom face, and a tabular positive tab and negative tab of the optically transparent battery fit in respective ones of the pair of grooves.

A flame simulating assembly is provided with a reflected flickering light that includes only one light source. Light from the light source passes through a rotating flicker element onto one or more reflectors, or mirrors, that reflect light up onto a simulated fuel bed and the some of the light is reflected off of the flicker elements towards a flame screen to create a simulated flame. The dipping flicker elements creates a fluttering light effect due to the flicker elements “intermittently dipping” into the light path. This fluctuating light is reflected onto the logs and ember bed in front and creates a dancing effect, which simulates glowing embers.

Systems and methods for shaping and energizing fluids to generate luminous fluid sculptures are disclosed herein. The disclosed methods comprise one or more steps of sculpting one or more fluids into a pattern or shape using one or more forces selected from the group consisting of mechanically generated turbulence, controlled movement through a shaped chamber, application of a magnetic field, vibration, and gravity to generate one or more sculpted fluids, and one or more steps of energizing the fluids using one or more sources of nonvisible energy selected from the group consisting of chemicals, heat, electrical current, and nonvisible electromagnetic radiation so that the fluids emit visible light. The color of the visible light emitted may be controlled by modulating various color-control factors. The methods comprise at least two non-simultaneous steps, where the non-simultaneous steps may be any combination of sculpting and energizing steps, to generate dynamic luminous fluid sculptures.

An article comprising natural stone and method for forming the article are provided. A counter-relief is formed at a back of the natural stone. A light-transmitting reinforcing material is bonded to the back of the natural stone at the counter-relief to reinforce the natural stone at the counter-relief. A front of the natural stone is carved to form a relief at the front. The relief is positioned opposite to the counter-relief. The thickness of the natural stone between the relief and the counter-relief is reduced by the carving to allow light to transmit through the natural stone from the back to the front to illuminate the relief.

A flame simulator includes a light beam source that projects a beam of light, a flame screen, a light beam mover that imparts movement to at least a part of the light beam source, and a range limiter. The light beam source includes a light source adapted to produce light and at least one light conditioner adapted to act on the light from the light source to produce the beam of light with a color, size and shape that mimics a flame when the beam strikes the flame screen. The range limiter is operatively associated with the light beam source so that the beam of light, when being projected, strikes at least a portion of the flame screen and causes illumination of the flame screen by the beam of light.

A moon Lamp is disclosed, which includes a base, a support seat and a lampshade assembly disposed above the support seat. A drive assembly for driving the support seat to rotate is provided in the base, a first groove is defined in an upper part of the base, and a first through hole is defined in a center of the first groove. The support seat includes a rotating shaft, a mount and a support bracket. The main control board and the lamp bead are arranged inside the spherical lampshade through a rotary connection between the support seat and the drive assembly of the base, and the drive assembly drives the support seat to move so as to drive the lampshade assembly to move, so that the moon Lamp presents different lighting effects and increases its use scenes.

A lighted artificial tree includes a first tree portion including a first trunk portion, first branches joined to the first trunk portion, and a first light string. The first trunk portion has a trunk connector and a first trunk wiring assembly, the first trunk wiring assembly is electrically connectable to the first light string and the trunk connector, and at least a portion of the first wiring assembly is located inside the first portion. The second tree portion includes a second trunk portion, second branches, and a second light string. The second trunk portion has a trunk connector and a second trunk wiring assembly, the second trunk wiring assembly electrically connectable to the second lighting string and the trunk connector. The second tree portion may be mechanically coupled and electrically connected to the first tree portion by coaxially coupling the first trunk portion to the second trunk portion.

An article comprising natural stone and method for forming the article are provided. A counter-relief is formed at a back of the natural stone. A light-transmitting reinforcing material is bonded to the back of the natural stone at the counter-relief to reinforce the natural stone at the counter-relief. A front of the natural stone is carved to form a relief at the front. The relief is positioned opposite to the counter-relief. The thickness of the natural stone between the relief and the counter-relief is reduced by the carving to allow light to transmit through the natural stone from the back to the front to illuminate the relief.

An LED diffusing assembly having a housing, a plurality of LED lights, and an LED control circuit. Each of the plurality of LED lights has a fixed intensity. Once activated the LED control circuit activates and deactivates each LED light at different times and for different intervals to create a flickering effect.

An apparatus, system, and related methods for light reflection with grooved surfaces are provided. The light reflection apparatus with grooved surfaces has a first surface with a quantity of grooves therein. A second surface has a quantity of grooves therein. The grooves in the second surface have a different angular shape, different size, different angular orientation, or a different unit density than the grooves in the first surface. At least one light source emits light on the first and second surfaces. As a direction of the emitted light changes relative to the first and second surfaces, the quantity of grooves in the first or second surface reflect the light independently of one another.
