LED lighting for HDTV broadcasts in the ratiopharm arena in Ulm
Modern HDTV transmission quality and super slow motion. To be able to exploit the full technical potential of these two TV standards, high performance cameras require professional, intense light. For example, for super slow motion, cameras record at around 300 frames per second. However, conventional lighting usually pulses at 50 Hertz. And this can be seen clearly on recordings of about 200 frames per second or more. The picture flickers, meaning the material is unusable.
The SiCOMPACT FL MIDI S of the OSRAM subsidiary is the world's first floodlight allowing sports lighting using LED technology, which not only meets current standards, but also offers light suitable for HDTV for high speed recordings. The SiCOMPACT FL MIDI S was developed especially for this requirement. A special ballast ensures that it works without pulse control and can also be dimmed. A world first in the illumination of sporting arenas!
The SiCOMPACT FL MIDI S was very successful in practical testing at the Plazamedia TV studio, the production company of the German channel Sport1. The result: Under the Siteco LED lighting, the highspeed recordings do not flicker, even at 1000 frames per second.
The ultramodern lighting solution has been used for the first time at the ratiopharm arena in Ulm, the new home of the major league basketball team ratiopharm Ulm. A total of 350 SiCOMPACT FL MIDI S illuminate the court, the stands and the stairways.
The ultramodern lighting solution also meets the requirements of the International Basketball Association (FIBA) for transmissions suitable for HDTV. Besides a vertical lighting strength of 2000 Lux, a high level of uniformity and good color reproduction are guaranteed.
Individual, energy efficient use for lighting of events
At the same time, the lighting installation can be used flexibly for all kinds of events. The SiCOMPACT FL MIDI S can be controlled individually using DMX and can be infinitely dimmed. At the same time, it only use as much current as is actually required for light.
In the test, the SiCOMPACT FL MIDI S also supplied suitable light for HD recordings at 300 frames per second, even with a 30 % power reduction. In addition, the luminaire need scarcely any maintenance. Compared to conventional lamps with a service life of 4,000 to 8,000 hours, the SiCOMPACT FL MIDI S can manage a service life of around 50,000 hours.
