History of the development of computer lights

Computer lights in the late 1970s and early 1980s began to appear on the television stage, initially used in some large outdoor concerts abroad, based on PAR lights, through motor control to produce swing and color change of the beam to the mid-late 1980s, computer light technology has been further developed, It has become a major leap in the development history of stage, film and television, and entertainment lighting. The computer lamp is equipped with a miniature computer circuit, which can receive the signal sent by the console and convert it into an electrical signal to control the mechanical part and achieve various functions

1. First-generation computer lights (1980s)

Simple function, limited movement and effect changes.

The control signal is not unified, and different manufacturers use different control protocols, and the universality is poor.

It is usually controlled by the manufacturer's own console and is limited by electronic technology.

2. Second-generation computer lamp (1987 DMX512 communication protocol)

The control protocol is unified to DMX512, which promotes the development of technology.

Manufacturers specializing in lighting consoles and computer lights have appeared.

With the advancement of technology, the power of the shaking head lamp is increased, the moving accuracy is improved, and the function of color change and pattern is enhanced.

3. Third-generation computer lights (early 21st century)

With the limitation of DMX512 communication protocol, network control technology is applied.

Art-Net network control protocol appeared, supporting two-way data transmission.

The lamps are equipped with monitoring and feedback chips and sensors, and can be upgraded through the network software.

4. Fourth-generation computer lights (digital computer lights)

Combined with digital display technology, complex effect changes are realized through digital layer processing.

Equipped with a media server, offering thousands of effects to choose from.

The application of network transmission control technology enhances the flexibility of lighting design and operation.
