Method for the operation and expansion of a network of lights Described herein is method for the operation and the expansion of a network of lights, each light in the network including a control module which is assigned to a group, each control module being in communication with a group controller as well as control modules in the same group. The network can be expanded by installing new lights with their associated control modules (19), and each new control module scans its environment and transmits environmental information to a central server (20) where the environmental information is analysed and the new control modules are allocated into groups (21). After allocation to a group in which control modules may be moved from one group to another or a new group is formed, the new control modules are available for normal operation. This process is repeated for each new light and associated control module.

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.

A multiway switching device may comprise a wireless device in communication with a relay and a manual switch of the device. A toggle state of the relay may be indicative of an electrical configuration between conductors and rectifier circuits of the multiway switching device. The wireless device may receive, from the manual switch or from an external device, a signal indicative of a modification to the toggle state of the relay. Based on the signal, the wireless device may cause the modification to the toggle state of the relay. The wireless device may cause output of a status signal indicative of the modification to the toggle state of the relay.

The present disclosure provides an intelligent music lamp string. The intelligent music lamp string includes a human body sensing module, a control module, a music control module and a lamp string. The human body sensing module is configured to sense a human body and output a sensing signal when the human body is sensed. The control module is configured to receive the sensing signal and output an enable signal and a control signal according to the sensing signal. The music control module is configured to receive the enable signal and play a predetermined music according to the enable signal. The lamp string is configured to receive the control signal and start to work according to the control signal, a duty cycle of the control signal in each cycle corresponding to beats of each section of the predetermined music.

An intrinsically safe (IS) luminaire disposed in a hazardous environment provides visible light and serves as a primary, auxiliary, back-up, and/or charging source of IS DC power for external devices disposed in the hazardous environment, such as process control devices and equipment. The luminaire includes a power converter that converts received power into DC power, an IS barrier that converts the DC power into IS DC power native to or utilized by a recipient external device, and a power distribution port via which IS DC power is delivered to the external device. In some configurations, the luminaire monitors communicates statuses, alerts, and/or other information corresponding to delivering IS DC power to one or more external devices to a host and/or portable communication device. The luminaire may include multiple IS barriers of same and/or different IS ratings, and may dynamically control activation/deactivation of the IS barriers and/or usages thereof.

A computer-implemented method performed by a device connected to a light and at least a first sensor is disclosed. The method includes: setting a first condition for activating the light; setting a second condition for deactivating the light; transmitting a first signal to the light to activate the light when the first condition is met; transmitting the second signal to the light to deactivate the light when the second condition is met; setting a third condition for activating the first sensor; receiving a signal from the first sensor; if the light is deactivated and the third condition is met, activating the light; and if the light is activated and the third condition is met, keep the light activated.
