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.
0-10 V lighting control. 0–10 V is one of the first and simplest electronic lighting control signaling systems, used as an early fluorescent dimming system. [ 1 ] Simply put, the control signal is a DC voltage that varies between zero and ten volts. Two standards are recognized: current sourcing and current sinking.
Pulse-width modulation(PWM), also known as pulse-duration modulation(PDM) or pulse-length modulation(PLM),[1]is any method of representing a signal as a rectangular wavewith a varying duty cycle(and for some methods also a varying period). PWM is useful for controlling the average poweror amplitudedelivered by an electrical signal.
DMX512 is a standard for digital communication networks that are commonly used to control lighting and effects. It was originally intended as a standardized method for controlling stage lighting dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols.

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 ...
October 12, 2024 at 2:37 PM. A dog whose rescue from Hurricane Milton floodwaters went viral this week is now safe, dry and “decompressing,” according to the Florida animal shelter now in ...
The Labor Department reported Thursday that applications for jobless claims jumped by by 33,000 to 258,000 for the week of Oct. 3. That's the most since Aug. 5, 2023 and well above the 229,000 ...
