A Voltage controller thyristor based dimmer rack An electrical schematic for a typical SCR-based light dimmer. A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, triodes for alternating current, silicon-controlled rectifiers or insulated-gate bipolar transistors, which converts a fixed voltage, fixed frequency ...
Dimming fluorescent ballasts and dimming LED drivers often use 0–10 V control signals to control dimming functions. In many cases, the dimming range of the power supply or ballast is limited. If the light output can only be dimmed from 100% down to 10%, there must be a switch or relay available to kill power to the system and turn the light ...
Since semiconductor or solid-state dimmers switch quickly between a low resistance "on" state and a high resistance "off" state, they dissipate very little power compared with the controlled load. Most recently, software programmable internal dimmers can use signals from the same switch that turns lights on and off to control dimming.

Digital Addressable Lighting Interface (DALI) is a trademark for network-based products that control lighting.The underlying technology was established by a consortium of lighting equipment manufacturers as a successor for 1-10 V/ 0–10 V lighting control systems, and as an open standard alternative to several proprietary protocols.
