To achieve the colorful effects of stage par light, precise and dexterous control mechanisms and corresponding controls are required. From manual to mechanical control, to modern electromechanical control, to current computer and network control, control technology is constantly changing and developing.

The control of candles, oil lamps, and gas lamps in the era of flame light sources is mostly manual and mechanical. The Sabatini dimmer in the 17th century used a rope to move the hood on the light source to adjust the brightness of the light source. In the electrical age, transformers were used for voltage regulation for a long time, but they were generally controlled manually. The speed is slow, the equipment is cumbersome, and the efficiency is low. Therefore, the mechanical dimming effect of par light is poor and labor-intensive.
In the late period of the electric light source era, electronic technology developed rapidly. Par light control also tends to be electronic. The initial electronic control is analog, which is an early resistance dimmer. Although it can make up for the labor-intensive shortcomings of mechanical dimming, it has low efficiency and low accuracy and is not suitable for large performance stages. With the emergence and development of digital integrated circuits, the digital control technology of par light is gradually applied to the lighting stage. The early thyristor electronic dimmers were later used for linear voltage regulation of triodes. At present, most of them use high-efficiency triode PMW voltage regulators.
The computer industry is growing at an astonishing rate, and the use of Ethernet and TCP/IP for dimming control means that there are a large number of off-the-shelf low-cost and numerous networking products and software resources, such as switches, cables, fiber-optic and wireless connectivity products, and remote control and monitoring technology. The traditional par light is controlled by the protocol, the main specification is 512 channels per channel, and the speed is 250 kb/s. It has always performed well in the par light industry, but with the increasing number of channels in lamps, it has exceeded expectations. To overcome the limitations of the protocol, a control protocol based on Ethernet technology is proposed. This enables multiple DMX data chains to be transmitted over a single network cable. The most direct benefit that can be obtained is the realization of functions such as transmission bandwidth, transmission distance, reliability, and two-way communication. This means that more devices can be connected at the same time in a network, and the connection distance is longer, the network transmission control protocol makes the dimming control quality and reliability higher, and the two-way communication makes the remote monitoring and control of the device more effective, so it is cheaper to build a large-scale and reliable dimming network. This is an inevitable result supported by modern computer network technology.
