A light source is provided with a digitally addressable lampshade that includes a plurality of regions of controllable opacity. Systems and methods are described for controlling the digital lampshade. In an exemplary embodiment, an addressable lampshade effects a time-varying pattern of changes to the opacity of the regions to generate a lamp identification pattern. A lamp is identified from the patterns by a camera-equipped mobile device. The mobile device then causes the identified lamp to generate a position-determining pattern of light. The mobile device determines its own position relative to the lamp based on the pattern of light received by the camera. The mobile device then instructs the digital lampshade, according to user input, to allow illumination or to provide shade at the determined position of the mobile device.

A lighting device is disclosed in the present disclosure. The lighting device includes a support assembly, an illuminant assembly, and a switch assembly. The illuminant assembly is connected to the support assembly and capable of being rotated to the support assembly. When the illuminant assembly is rotated to a position at which an angle between the illuminant assembly and the support assembly is less than or equal to a first angle threshold, the switch assembly turns to an on-state. In this way, the lighting device has a function of a switch.

Lighting devices, systems, and methods for selectively activating S cones and L+M cones in a human retina and for regulating the phase of circadian rhythm in a human subject.

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 light-emitting unit includes a plurality of lenses; and two or more light-emitting devices covered by each of the lenses, and the two or more light-emitting devices covered by one lens of the lenses are electrically separated from each other.

Provided is a light-emitting device with reduced in-plane luminance variation. The light-emitting device includes a main substrate, a plurality of light sources, a plurality of lenses, and one or more light reflection members. The main substrate includes a central part and a peripheral part that surrounds the central part. The plurality of light sources are each disposed on the central part of the main substrate. The plurality of lenses are disposed to correspond to the plurality of light sources respectively. The plurality of lenses apply optical effects to beams of light from the plurality of light sources respectively. One or more light reflection members are each disposed on the peripheral part. The light reflection members each have reflectance that is higher than the reflectance of the main substrate.

Apparatus and associated methods relate to a water dispensing lamp (WDL). In an illustrative example, the WDL may include a base module disposed on a horizontal plane, and a fluid dispensing stem coupled above the horizontal plane along a vertical axis. The fluid dispensing stem, for example, may include an electrical pump and a dispensing element. For example, the electrical pump may be configured to pump fluid out of the dispensing element towards the base module. In some implementations, the WDL may include a lamp shade coupled to the fluid dispensing stem. Various embodiments may advantageously conceal the dispensing element by the lamp shade unless a viewing angle between the horizontal plane and a viewing axis is larger than a predetermined viewing angle threshold.

Illuminated top furniture including an illuminated top portion and a support portion. The illuminated top portion includes a support layer, at least one light source, a light diffusion layer and an upper protective layer. The at least one light source is mounted to the support layer. The light diffusion layer is positioned on a side of the at least one light source that is opposite the support layer. The upper protective layer is positioned on a side of the light diffusion layer that is opposite the support layer. At least a portion of the upper protective layer is transparent such that light emitted by the at least one light source is visible through the upper protective layer while the light diffusion layer obscures the at least one light source so that the at least one light source is not visible through the upper protective layer. The support portion is attached to the illuminated top portion to support the illuminated top portion above a ground surface.

The present invention relates to a polar light projector, including a housing and an upper cover which form a containing cavity, the containing cavity is internally provided with a light-emitting lamp path component, a laser lamp path component, a main control board, a horn and a cavity bracket, the cavity bracket is provided with a motor fixing groove and a limiting wall, the light-emitting lamp path component is arranged in the limiting wall, a motor is placed on the motor fixing groove and is fixed through a fixing lug, a refracting surface of an optical lens is formed by splicing a plurality of curved striped prisms. The refracting surface of the optical lens makes a light path of the light-emitting lamp path component form a aurora pattern that is projected to the outside, and a drive component is arranged to drive an aurora sheet to rotate, thereby presenting a dynamic aurora.

A free-standing accessory stand that includes a ground support portion and an enclosure is provided. The enclosure is disposed about a central axis of the accessory stand. The upper surface faces away from the ground support. The accessory stand includes a retractable accessory support that has an outer surface projecting away from the enclosure in a first configuration. A mounting space is provided along the outer surface of the retractable accessory support above the upper surface of the enclosure. The outer surface is retracted in a second configuration.
