Victoria Falls Bridge
Architectural Project in Zimbabwe illuminating the whole bridge, generating > 60% energy saving.
Details
The LED products used were 12 X Philips CK Reach PowerCore RGB Generation 2 LED spotlights.
It's important to note that 6 of each of the LED flood lights are positioned at the feet and sides on either end of the Bridge (Six in Zambia and Six in Zimbabwe). With the use of the CK Philips Data Enabler Pro, SSLI merged the line voltage and control data allowing communication with each spotlight on a single standard cable, dramatically simplifying installation and lowering the total system cost.
The RGB controller -Philips CK iPlayer3 and City theatrical -DMX Wireless emitter –VERO are positioned on the Zimbabwe side of the bridge and all information is communicated digitally across the 198m Gorge to a VERO DMX Wi-Fi receiver that communicates with the floodlights positioned on the Zambian side thus eliminating the need for the running of expensive cable across the bridge span.
The Floods lights have been installed with versatile optics that allow for exchangeable spread lenses allowing for multitude of applications. In this project the beam angles range from:
• 5 degrees aimed at the middle point of the bridge from either side;
• 8 degrees positioned under the bridge spans;
• 13 degrees aimed at the midway of the bridge;
• And 23 degrees beams aimed at the main bridge spans.
Benefits
The LED Floodlights each use at full capacity 290 watts of power yet they are able to throw the light up to 665 feet (202.7 meters).
The Total Power consumption of this solution is <3,8 kW. Thus consuming >60% less energy than the 800w High Pressure Sodium lamps which traditionally illuminated a portion of the Zimbabwean side of the bridge base.
The Lamps and the control solution are capable of producing a dynamic colour palate of 18,5 million colours. The Philips CK Colour reach power core produces a saturated, cost effective colour due to the fact that the unit is made with high performance LEDs that offer saturated colour at a significantly lower cost of installation, operation, and maintenance than traditional light sources.
The solution has also been designed to illuminate the Bridge in the colours of celebrated International recognized days such as:
• World Breast cancer day - the bridge will be Pink (4th February)
• World Aids day - the bridge will be Red (1st December)
• World Diabetes day - the bridge will be baby Blue (14 November)
• World environment day - the bridge will be green (5th June)
• Zimbabwe Independence Day (18th April)
• Zambian Independence Day (24th Oct)
