    en.wikipedia.org/wiki/Wireless_light_switch

    Dimmer light switch with RF-based remote control [1] A wireless light switch is a light switch that commands a light or home appliance to turn itself off or on, instead of interrupting the power line going to the light fixture. There are different ways to communicate between the switch and the fixture: [2]

    The box needed to output radio frequency signals (compatible with a television's antenna input), composite video, and stereo audio. It had to include a remote control, and be compatible with universal remotes. The units had to support both a 4:3 center crop of a 16:9 transmitted image, and a letterboxed rendition of a 16:9 transmitted image.

    en.wikipedia.org/wiki/RDM_(lighting)

    Remote Device Management (RDM) is an addition to the DMX512 control protocol for stage lighting equipment, introduced in 2006. DMX512 was developed in the late 1980s as a standard protocol for lighting consoles to communicate with dimmers , but has since been used for more complex applications, including the control of intelligent lighting ...

    en.wikipedia.org/wiki/Reconfigurable_antenna

    A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...

  6. Dimmer - Wikipedia

    en.wikipedia.org/wiki/Dimmer

    Dimmer in a residential application with RF-based remote control. Non domestic dimmers are usually controlled remotely by means of various protocols. Analogue dimmers usually require a separate wire for each channel of dimming carrying a voltage between 0 and 10 V. Some analogue circuitry then derives a control signal from this and the mains ...

  7. Lighting control system - Wikipedia

    en.wikipedia.org/wiki/Lighting_control_system

    A major benefit of lighting control systems is reduced energy consumption. Longer lamp life is also gained when dimming and switching off lights when not in use. Wireless lighting control systems provide additional benefits including reduced installation costs and increased flexibility over where switches and sensors may be placed. [3]

  8. Light switch - Wikipedia

    en.wikipedia.org/wiki/Light_switch

    This "quick break" technology is still in use in almost every ordinary light switch in the world today, numbering in the billions, as well as in many other forms of electric switch. The toggle light switch was invented in 1916 by William J. Newton. [2] As a component of an electrical wiring or home wiring system, the installation of light ...

  9. DMX512 - Wikipedia

    en.wikipedia.org/wiki/DMX512

    Typically a dimmer has a starting address that represents the lowest-numbered dimmer in that pack, and the addressing increases from there to the highest-numbered dimmer. As an example, for two packs of six dimmers each, the first pack would start at address 1 and the second pack at address 7. Each slot in the DMX512 packet corresponds to one ...
