A lamp projecting a starry sky is provided. The lamp projecting the starry sky includes at least one beam generator, a reflecting member with uneven and irregular reflecting surface, a first motor, and at least one first lens. The first motor is connected to the reflecting member through a connecting shaft, the reflecting member is driven to rotate when the first motor rotates, a light beam generated by the beam generator irradiates onto a first side of the reflecting member along an incident light path, and a light beam emitted from the reflecting member forms a moving and layering nebula projection after passing through the at least one first lens. In the lamp, after passing from the reflecting member, the light beam is magnified by the lens, so that the generated starry sky will not be too bright and dazzling, which effectively enhances the layering sense of the starry sky.

A light box includes a light passing cover printed with an image. The image is being logically divided into two-dimension blocks. The light box includes multiple light tubes. Each light tube includes a tubular housing, an elongated LED bar, and a controller. The elongated LED bar is being enclosed by the tubular housing. The elongated LED bar has multiple LED modules divided into multiple LED sections. The multiple light tubes is being disposed behind the image of the light passing cover. The multiple LED sections of multiple light tubes is being corresponding to the two-dimension blocks of the image respectively. The controller controls the multiple LED sections separately according to a stored script. The stored script indicate a timing sequence for controlling the multiple LED sections for illuminating the two-dimension blocks of the image according to the stored script.

The fixtures may be independently addressable. The fixtures may be magnetically supported by a fixture support. A brace may join two or more fixture supports without reducing space available to support fixtures. The brace may join a fixture support to a fixture support accessory. An accessory may include a variable-angle junction. The fixture may include articulating joints for controlling the direction of a beam. The fixture may include a lens having an electrically controllable beam spread angle. The fixture may be stowable in the fixture support. The fixture may be slidable along a cord to adjust a height of the fixture. The fixture may include an extendable ring. The system may coordinate motions of the fixtures to follow a target. The fixture may include an elongated board. The elongated board may include a non-polar power socket.

The lighting management system includes: a judgement unit configured to judge whether or not a lighting state around a vehicle based on a first lighting apparatus and a second lighting apparatus meets a first reference for a light amount and a second reference for at least one of a lighting range, a lighting color, and a flashing state; a first control unit configured to control the light amount of at least one of the first lighting apparatus and the second lighting apparatus so that the lighting state is brought to meet the first reference; and a second control unit configured to control at least one of the lighting range, the lighting color, and the flashing state of at least one of the first lighting apparatus and the second lighting apparatus so that the lighting state is brought to meet the second reference.

The present disclosure discloses a lamp for water mist in the shape of a flame, which includes a base, wherein a water tank is arranged on the top of the base, an ultrasonic atomizer is provided at the bottom of the water tank, an upwardly protruding component is centrally arranged at the bottom of the water tank, a plurality of supporting blocks are arranged at the bottom of the spacer plate near the through hole, and a baffle plate is arranged between the supporting blocks and the protruding component, a channel is formed between the spacer plate and the baffle plate, and a plurality of LED lights are provided on the top of the water tank, a housing is provided outside the water tank, the top part of the housing is provided with a top cover having a lamp hole.

Disclosed is a lighting assembly for providing electrically configured light distributions and illumination patterns. The light distributions can be pre-configured and stored in a memory device or adjusted once installed in an environment by use of a wired or wireless controller or control device. The lighting assembly comprises at least one primary transmissive optical element and multiple light sources arranged in two or more independently addressed electrical channels spatially arranged on a common plane of the lighting assembly housing. Each light source channel is both physically separated and electrically adjustable in order to control light input into the optical element and subsequently adjust the light distribution output of the lighting assembly. The lighting assembly can be used to provide a wide range of symmetric and asymmetric lighting distributions for direct or indirect lighting as well as focusing or defocusing a projected beam in a spotlight or downlight configuration. The lighting assembly is therefore useful in a wide range of typical indoor and outdoor lighting applications including downlighting, spotlighting, wall washing, cove lighting, retail lighting, warehouse lighting. It is also possible to produce useful tunable white or color related lighting effects wherein different color temperature variants of white or different colors, such as red, green or blue might have different lighting distributions.
