The invention provides a junction box with several switchable function modules. The junction box has a box container providing the input of plurality of external wires. There are several wire connectors positioned inside the box container, wherein each of the wire connector having a first opening and a second opening, each of the second openings is provided for accommodating one of the external wires. In addition, a box cover having a function module is provided for being mounted on the box container. Once the box cover being mounted on the box container, plurality of contact pins set on the box cover would be inserted into the first openings of the wire connectors then the contact pins would be in electrical communication with the external wires. Therefore, the function module, which is in connection with the contact pins, would be activated.

The invention provides an assembly comprising a locking element and a plug module (20) connected to a socket (30); the locking element (10) comprising: a fastening means (12) configured to constrain a rotation of the locking element around the centerline of the socket; a main body (13) comprising a circumference; at least one spring plate (11) coupled to the main body and freely extending along a part of said circumference; wherein the at least one spring plate is deflectable between an initial position and a deflected position, wherein in the initial position the at least one spring plate protrudes in the axial direction of the centerline, the at least one spring plate being configured to engage a base surface of the plug module and to deflect away from said initial position into the deflected position, thus enabling the rotational movement of the plug module in the first rotational direction.

There is provided an LED light with a replaceable module that is connected to an intelligent network. The replaceable module includes a driver element, communication element, and power storage such as a battery. The driver element has circuitry, such as printed circuit boards, which is uniform for mating with any connection component to provide electrical connection. The communication/control element includes communication with a voice orchestrated infrastructure and to Z-link capable systems, via a wireless network. The replaceable module fits inside the opening of a housing which includes a mount for electrical connection to standard electrical outlet. Zone control LED lighting is also provided which is likewise connected to the network for voice control.
