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.

An integrated ceiling device includes a housing retaining an electronic assembly, a heat sink having a central opening, a light source coupled onto the heat sink, the housing is coupled with and disposed at least partly above the heat sink, and a central vertical axis of the housing aligns or is in proximity with the central opening of the heat sink.

A reflector and of a holding-plate slidingly attach to each other to form a flangeless trim assembly. The reflector may be removably attached to a spackle-frame. The spackle-frame may be installed within ceiling drywall around a hole for a downlight. The holding-plate may be attached to a lighting module. In a default resting configuration, a top of the reflector butts up against a bottom of the holding-plate because springs push these two parts towards each other. When an opposing force is applied that is greater than the spring's force, then a variable gap is formed between the reflector and the holding-plate, but while the reflector and the holding-plate are still attached to each other. This gap may be used by human finger(s) to both disengage the reflector from the spackle-frame and to pull down the reflector, the holding-plate, and the lighting module from the spackle-frame—all without tools.

Light systems, systems and apparatus related thereto that aids in the installation and removal of a luminaire as well as eliminates gaps formed in a housing for the light system. The light system includes a spring-loaded attachment system for a light system, a mounting system in which a luminaire can be arranged therein that includes interchangeable plates to accommodate various size and shape luminaires, and a light-blocking rotatable housing assembly for a recessed luminaire.

A junction box can include an enclosure defining a first enclosure end and a second enclosure end, a cavity extending into the enclosure from the first enclosure end towards the second enclosure end, the first enclosure end defining an opening to the cavity; a mounting insert removably positioned within the opening; and a locking collar removably coupled to the first enclosure end, the locking collar being repositionable on the first enclosure end between a tightened configuration and a loose configuration, the locking collar securing the mounting insert to the enclosure in the tightened configuration.

A junction box for a light fixture. The junction box is configured to be mounted to a desired surface within an environment and includes a housing, a bracket coupled to the housing, an internal cavity defined by the housing and the bracket, a driver disposed in the internal cavity, an adapter removably disposed within the internal cavity, and a cover removably coupled to the adapter to selectively close the internal cavity. The cover includes an opening configured to receive a portion of the light fixture to removably couple the light fixture to the junction box. When the cover is coupled to the adapter, the adapter retains the driver in the cavity and prevents access to the driver, and when the cover is removed, the adapter is removable from the cavity, thereby permitting access to the driver.

A downlight apparatus includes a light source, a light housing and a stop unit. The driver box is used for storing a driver. The driver is connected to an external power source to generate a driving current to the light source. The driver box has a wall with an installation escape. The light housing has a light holder and a rim. The light source is stored in the light holder. The rim defines a light opening for a light of the light source to escape. The stop unit is fixed to the installation escape. The stop unit has a switch holder and a wire holder. A manual switch is placed in the switch holder and an enlarged wire head of an power wire is placed in the wire holder. An operation part of the manual switch is exposed outside the driver box. The manual switch is connected to the driver for adjusting a setting of the driver.
