For the lighting of the thermal Pantheon in Villa dei Cedri we decided to install the full stainless steel 316L version of Ego and Ego Maxi with full colour RGBW LEDs. The plan needed a control by DMX protocol associated to device programmability via RDM protocol once it was installed.
Such a technology allowed to organize the lamps so as to arrange three concentric circles of large diameter with all the lamps having a unique control system so that you can control them as a single pixel. Each light source, therefore, can create a different colour from the others, controlled by a scenic program managed by a computer.
In addition to this technical aspect and due to the project conditions in place, the design studio request was to avoid watertight distribution boxes inside the tanks. Then we had to provide long wiring of over 30 meters going from each single projector to external technical compartments, accessible out of water.
To overcome the limit of DMX connections, which require the Daisy Chain, or the Ad Hoc DMX connection "enter/ exit", 8-channel SPLITTERS have been developed, that is electronic boards dedicated to the reconstruction of the DMX signal and its amplification, which actually work as a central point of star connection to the various lamps.
This way, the sum of the cable lengths - which would have exceeded the total length expected by the physical layer RS485, that is that of the DMX - have been traced back only to the output from each single lamp.
This special kind of connections made with removable connectors inside IP67 boxes has guaranteed a clean design that allows you to operate at any time on the single lamp simply by detaching it from the complete system.
The use of latest generation multichip LEDs combined with Colour Mixing lenses has allowed us to get bright colours and a uniform lighting without any compromise.
