A light-and-shadow decoration includes a main decorative object, an omnidirectional rotation mechanism, and an electrical control unit. The main decorative object includes a three-dimensional structure and has one side that is provided with a retaining seat. The omnidirectional rotation mechanism includes a support axle, a rotation base, and a projector. The support axle has two ends each provided with a universal-joint ball. The rotation base and the projector are respectively connected to the two ends of the support axle. The projector has one side on which a lighting cover is mounted. The electrical control unit includes a power supply portion and at least one light-emitting element. Light from the light-emitting element transmits through the lighting cover to project to the outside. As such, the omnidirectional rotation mechanism enables rotation of the light source relative to the main decorative object and the support axle for adjusting a projection direction thereof.

A method and apparatus for quick, safe, and easy installation of electrical fixtures in the building construction field, including connecting the fixture to a mounting mechanism for structural support and electrical service. A coupling mechanism is attached to or incorporated into the fixture. The coupling mechanism has built-in electrical leads that are designed to connect with the electrical leads on a fixture-facing interface of the mounting mechanism. Electrical leads on the coupling mechanism are connected via wire or other electrically conductive material to the electrical components in the fixture.

A lighting fixture includes a housing, a first light source, a light guide plate, and a second light source. The housing has an inner cavity and a mounting hole, the mounting hole communicates the inner cavity with an external environment of the housing, the light guide plate is installed in the mounting hole. A side of the light guide plate faces the inner cavity, the other side of the light guide plate faces an outside of the housing. The second light source projects second light to the light guide plate, the second light is capable of being projected to the outside of the housing through the light guide plate. The first light source projects first light, and is configured such that the first light is projected to the outside of the housing through the light guide plate, and the housing is a non-light-transmitting housing.

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.
