Emerald has been working with show business for over 25 years and is a pioneer in the field of multimedia visualisation. The latest highlight is a multimedia chandelier using RGB LED technology. For this design, almost four thousand independent digital diode modules were arranged in two circles in 104 light hoses.
The chandelier features its own control system that enables previously recorded light scenes to be played. It can also be used for live shows, as well as shows where the chandelier is synchronised with other lighting and decorating elements in the gallery such as a fountain. By equipping it with a series of water nozzles, it is also possible to combine water and light to allow for various animations. The entire system is supplemented by a timer.
Another system enables monitoring of the data transmission to the customer’s separate remote network. This allows the shows to be controlled from the gallery at the venue or from anywhere in the world via a remote network. Virtual private network technologies and tunnel encryption with strong cryptographic methods are used to secure the data transmissions.
LAPP in Poland advised the customer and found solutions precisely tailored to their ambitious needs. Two things were particularly important to the customer with regard to the cables. Firstly, the cable packaging should prevent any errors during installation. Secondly, a wide selection of insulation colours should be available to enable rapid identification of the individual circuits. LAPP was able to fulfil both of these requirements. The H05V-K and H07V-K single cores used were packaged in separate and clearly labelled boxes.
Cables from the same group were also used for the connection solutions inside the control cabinet, as the copper conductors are made of thin wires (in accordance with IEC 60228 class 5). As a result, they are highly flexible, have very small bending radii and require very little space for connections. The control cables were fixed in the control cabinet with SKINTOP® ST-M conduit glands. The high protection class IP68 was achieved using a neoprene ring. One great aspect of the conduit glands in this SKINTOP® series is a wide sealing area. This was achieved using special lamellas in the housing design. Inside the head, there is an integrated anti-vibration system which protects the element from twisting out.
Every light in the chandelier can be controlled independently. This enables their colour and light intensity to be adjusted in real time. The image refreshing period can be up to 25 ms, which enables smooth colour transitions. Many special transmission standards and protocols (DMX, ART-NET, TCP-IP) were employed for the design of the chandelier. Data is transmitted using UNITRONIC® LAN 500 S/FTP Cat.6A data cables. UNITRONIC® LiYCY (TP) data cables were used for the DMX protocol. This type of cable features shielding made of tin-plated copper wires, thus offering excellent interference resistance. So, let the show begin!
