LED DMX Technology

The term LED DMX technology refers to the use of DMX512 controllers to manipulate light-emitting diodes .

A DMX controller uses EIA-485 differential signaling at its physical layer in order to adjust the amount of photons, in addition to the amount of light, released by an LED.

LED DMX technology is most common in the performing arts such as theater and dance, where the lighting is usually combined with other special effects such as a fog machine or strobe lights.

A particular LED is assigned an identification number such as “12," and by sending particular electrical signals to the identification number, LED DMX technology can adjust the brightness, color and other characteristics of the diode. For example, by programming the command “12-40%," a DMX controller could reduce the brightness of a light-emitting diode to 40 percent of the maximum output.

LED DMX technology has become increasingly popular because of the DMX512 cable’s sturdy, robust construction that protects it from damage that is easily sustained by other high-speed transmission cables.

Wireless DMX transmissions to control LEDs, in particular, are often installed in architectural lighting networks because they are reliable even up to distances of 2,000 feet .

Modern LED DMX controllers also utilize frequency hopping spread-spectrum technology together with cognitive coexistence to minimize interference with other wireless networks.
