  2. TRIAC - Wikipedia

    en.wikipedia.org/wiki/TRIAC

    A TRIAC (triode for alternating current; also bidirectional triode thyristor or bilateral triode thyristor [1]) is a three-terminal electronic component that conducts current in either direction when triggered. The term TRIAC is a genericised trademark.

  3. Dimmer - Wikipedia

    en.wikipedia.org/wiki/Dimmer

    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 ...

  4. Lighting control console - Wikipedia

    en.wikipedia.org/wiki/Lighting_control_console

    Many memory consoles have a bank of faders. These faders can be programmed to control a single channel (a channel is a lighting designer's numerical name for a dimmer or group of dimmers) or a group of channels (known as a ""submaster""). The console may also have provision to operate in analog to a manual desk for programming scenes or live ...

    en.wikipedia.org/wiki/0-10_V_lighting_control

    0-10V dimmer In production lighting this system was replaced by analog multiplexed systems such as D54 and AMX192 , which themselves have been almost completely replaced by DMX512 . For dimmable fluorescent lamps (where it operates instead at 1–10 V, where 1 V is minimum and 0 V is off), the system is being replaced by DSI , which itself is ...

  6. Thyratron - Wikipedia

    en.wikipedia.org/wiki/Thyratron

    Rare Z806W relay tube used in elevators. Low-power thyratrons (relay tubes and trigger tubes) were manufactured for controlling incandescent lamps, electromechanical relays or solenoids, for bidirectional counters, to perform various functions in Dekatron calculators, for voltage threshold detectors in RC timers, etc. Glow thyratrons were optimized for high gas-discharge light output or even ...

  7. Light switch - Wikipedia

    en.wikipedia.org/wiki/Light_switch

    Two light switches in one box. The switch on the right is a dimmer switch. The switch box is covered by a decorative plate. The first light switch employing "quick-break technology" was invented by John Henry Holmes in 1884 in the Shieldfield district of Newcastle upon Tyne. [1]

  8. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

  9. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
