Lighting technology

from Wikipedia, the free encyclopedia

Lighting technology or lighting technology refers to all technical measures that serve to influence lighting conditions. In addition to lighting through the use of lights and directing daylight in buildings, this includes signaling through light . Lighting technology is also important in event technology , especially stage technology , as well as in film production and photography .

In lighting technology for events, on the one hand, the devices used are divided into conventional and intelligent lighting devices. In addition to traditional PAR spotlights, conventional effects include so-called blind spotlights , but also lens spotlights (e.g. Fresnel spotlights or, in German technician jargon, also called Fresnel lenses). The intelligent headlights include, on the one hand, the increasingly widespread swivel heads or moving heads and, on the other hand, the scanners, which are becoming less important . Strictly speaking, show lasers for the presentation of laser shows as a special form of lighting technology also belong to intelligent lighting devices. The use of LED lamps is becoming more and more important ; they are used both as conventional light (e.g. LED PARs) or intelligent light (LED video wall, surface LEDs, LED tubes). A clear assignment is difficult here. With the advent of LED technology, there is also an increasing amalgamation of lighting and video technology in event technology .

Lighting technology in event technology is also differentiated according to its purpose. Depending on whether the light is used artistically in the theater, on so-called rock 'n' roll productions (this mainly includes large concert and tour productions), at industrial events (general meetings, trade fairs and exhibitions), film and television recordings or in the Disco are used, there are very different requirement profiles. In connection with this, different terms that are traditionally based (see stage technology in the theater) are also common. In some cases, however, the boundaries of this division are blurring, for example more and more head swiveling devices are used in the theater, which was previously rather unusual.

Most lighting technology devices can produce either one or more colors from the entire spectrum of visible light. In addition, soft or hard light , wandering light, flashes or blinking can be produced. The effects and moods that can be created with it are very diverse.

The lighting technology works with light sources ( headlights ), screens and filters as well as mirrors . It is mostly controlled electronically. Bus protocols used in event technology are, in addition to DMX-512, increasingly also Artnet and related protocols. The various settings and lighting moods are changed with the help of lighting consoles . In the home and industrial installation sector, EIB has established itself as a bus system.

A specialist in lighting technology is the lighting master in image production and in the theater, or sometimes just the lighting technician or lighting technician . Lighting designers are also used for planning industrial events and concert productions. The installation of the lighting technology is usually carried out by specialists for event technology and masters for event technology .
