2. Distribution board - Wikipedia

   en.wikipedia.org/wiki/Distribution_board

   In a theatre, a specialty panel known as a dimmer rack is used to feed stage lighting instruments. A U.S. style dimmer rack has a 208Y/120 volt 3-phase feed. Instead of just circuit breakers, the rack has a solid state electronic dimmer with its own circuit breaker for each stage circuit. This is known as a dimmer-per-circuit arrangement. The ...

   en.wikipedia.org/wiki/Light_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 switches is regulated by some authority concerned with safety and standards. In different countries the standard dimensions of the wall mounting hardware (boxes, plates, etc.) may differ.

   A thyristor dimmer rack An electrical schematic for a typical SCR-based light dimmer Solid-state , or semiconductor , dimmers were introduced to solve some of these problems. Semiconductor dimmers switch on at an adjustable time (phase angle) after the start of each alternating-current half-cycle, thereby altering the voltage waveform applied ...

7. Lighting control console - Wikipedia

   en.wikipedia.org/wiki/Lighting_control_console

   A lighting control console (also called a lightboard, lighting board, or lighting desk) is an electronic device used in theatrical lighting design to control multiple stage lights at once. They are used throughout the entertainment industry and are normally placed at the front of house (FOH) position or in a control booth .
