A lamp assembly includes a base, a support arm coupled to the base, a housing coupled to the support arm, a mirror supported by the housing, a light arrangement supported in the housing, wherein the base, the support arm, and the housing are reconfigurable between a first configuration where the housing is located vertically above the base and a reflective surface of the mirror is parallel with a worksurface, a second configuration where the housing is located vertically above the base and the reflective surface is perpendicular to the worksurface, and a third configuration where the housing is located at least partially rearward of the base and the reflective surface is substantially perpendicular to the worksurface. The lamp assembly may further include a support member configured to cooperate with the base to support a personal communication device, and a rotatable portion of the housing which controls a light intensity.

Apparatus and methods for deployment of fixtures. The apparatus may include a system for controlling deployed fixtures. The system may receive user commands different devices in different formats. 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 utility model discloses a projecting device for generating a light effect of a galactic starry sky, including: a light-emitting assembly including at least one first incoherent light source and at least one first condensing lens, the first condensing lens being arranged on an illuminating surface of the first incoherent light source; a film assembly including a film sheet provided with a galactic starry sky pattern, the film sheet being arranged on the other side of the first condensing lens relative to the first incoherent light source; and an imaging assembly including at least three lenses, the three lenses being an imaging lens, an adjusting lens, and a wide-angle lens arranged sequentially in a projection direction of the film sheet, respectively. The technical solution of the utility model effectively improves practicality of the projecting device by setting a plurality of functional lenses.

A jewelry lighting lamp has a lighting part, a rotating part and a mounting part, the mounting part has a lamp barrel which accommodates the lighting part and rotating part. The rotating part has a driving motor, which drives the lighting part to rotate along the central axis of the lamp barrel; the lighting part has a main light source arranged on the central axis and one or more secondary light sources arranged around the main light source, the main light source and the secondary light source are driven by the rotating part to rotate along the central axis circumferentially. A jewelry lighting method using the jewelry lighting lamp is also provided. By varying luminance, the lamp solves the problem of visible light and shadows at the edge of the aperture when there are main and auxiliary light sources with different luminance.

The LED grow-light system includes one or more grow-light canopies with linear LED light bars to provide upward and/or downward lighting in a central illumination area. The LED grow-light system or grow-light canopies are preferably constructed using T-slot interconnects that lock into T-channels of the T-slot bars and/or T-slot light bars and the LED grow-light systems are housed in a controlled modular grow-light containers that include sky-light structures and/or light tubes that allow the controlled modular grow containers to be stacked or placed next to each other and minimize the footprint for growing plants.
