Low energy consuming LED’s used to illuminate an artwork on top of Cape Town famous Signal Hill that symbolises the transition from past to future and that will act as a beacon of hope for all to see.
The artwork unveiled this week on top of Signal Hill by Sun International called the “Sunstar” is designed by artist Chris Swift and forms part of a project themed “the PharoX”. It is a five storey high tetrahedron star shape that incorporates old fencing reclaimed from the Robben Island prison. The structure is lit by using global leaders in LED lighting NTL Lemnis Pharox brand of LED’s. This result is a spectacular cohesion of structure and light in the form of an “X” shape viewed from different angles, thereby serving as new beacon for the whole of Cape Town to see. At night the Illuminated structure is seen clearly by incoming aircraft, as well as citizen and visitors to Cape Town as far as 25km’s away.
The design, a third expose` where the artist has collaborated with local African subsidiary NTL Lemnis Africa by incorporating the use of their Pharox LED’s in his artworks, delivers a significant display of many symbolisms continuing on the theme of using our past to move to future, representing a crossroad in the South African democracy and the significance of combining sustainable energy solutions and historical pieces – the result is sure to be a piece that will draw a lot of attention and discussion over the coming months. Most importantly it serves as a reminder of our past and the significance that Signal Hill played to those incarcerated at the infamous Robben Island.
Previous projects by Swift include a Christmas tree using the same fencing, discarded cable drums and Pharox LED bulbs in 2012 at the South Africa Museum in Cape Town, as well as, a successful art exhibition by the artist using Pharox LED tubes with the theme “The Void: Positive/Negative spaces” held in 2013.
From a sustainable energy and technology use perspective – the combination of using the low energy consumption, high performance and weatherproof Pharox LED strip lights with a completely off-grid PV generation platform engineered and provided by well-known Eldo Energy, enables the artwork to shine during night without consuming any grid supplied electricity, and with minimal impact on the surreal surrounding of Signal Hill.
Francois van Tonder, CEO of NTL Lemnis Africa: “ As global leaders in the field of LED lighting since 2005, it pleases us tremendously that our Pharox brand of LED’s feature in this and other artworks, the technology was selected based on our reputation for high quality and high performance LED products with very low energy consumption. As a company credited with the first mass rollout of LED bulbs in Europe of nearly 3 million Led bulbs initiated by our holding company in 2009, as well as the achievement of a world-first LED Carbon Credit offset project accredited here in South Africa in 2012, our interests lie not only in bringing excellent LED lighting technology to the South African consumer, but also to contribute meaningfully in the non-commercial sphere. Further as part of our sustainable social investment initiatives and as a result of this project, we will continue with our donation of Pharox LED bulbs and lighting products to various projects like the Masikule PHP 800 (People’s housing Project) started in Khayelitsha in 2012 - we also dearly thank everyone involved in the project.”The Sunstar sponsored by Sun International and forms part of Cape Town’s World Capital Design 2014 initiative, and in collaboration with the City of Cape town and the Robben Island Fence Company and Trust, will serve to be a beacon of hope – and of light over the coming months.
Wearable devices are still in its early phases, where manufacturers can be creative in design. Ritot, a Ukraine-based startup has abandoned screen designs, who needs a LED or OLED screen displays if all the information you need can be projected onto your wrist?
Be warned, though, the company currently does not have a workable prototype, so all images advertising the smart watch on Indiegogo are nothing more than 3D rendered images of the final product. Nonetheless, the implications of the proposed smart watch design could go far.
LED stands for Light Emitting Diode.
LED Illumiation, as well as CFL illumination (Compact Fluorescent Lightsin Spanish CFL), has come to revolutionize the market of lighting given its high efficiency , and sometimes, given by regulations that prohibit or discourage the manufacture of incandescencent light bulbs. The principle is similar to the ionized gas tubes, thanks to the action of a diode.
The first LED application was on indicators of electrical panels and electronic components. In a second phase they were used as ornamental lighting that could be found in some Christmas decorations and lantern-based lighting system.
LED bulbs mimic the effect of a classic bulb through a cluster of up to 200 small lighting units, whose purpose is to be able to be screwed in conventional caps. The beam produced by these small units is expanded with diffusers and lenses that spread the beam according to the desired lighting effect. This is so because unlike incandescent lighting systems, LED lighting is essentially unidirectional, which resulted in its domestic use being limited to study lamps.
"Lumen employs energy-saving technology with LED tiles that boast the lowest power consumption in their class. To offset some of the carbon emissions on Lumen, Absa is building one of the largest rooftop solar photovoltaic farms on top of Absa Towers North in South Africa.
Johannesburg is set to take its place alongside the world's most iconic cities with 'Lumen' which will become an instantly recognisable global landmark transforming the city's skyline.
Absa, a member of Barclays, today switched on the world's largest Light Emitting Diode (LED)display. This world first will transform the Absa Towers building in Johannesburg's CBD making it an instantly recognisable icon in the city's skyline. The technological innovation is an integral part of a wider ten-year inner city rejuvenation project that Absa has embarked on and shows its commitment to the City of Johannesburg as a leading centre for business on the African continent.
Crowning the 29 storey-high Absa Towers building, each of the four giant LED screens is almost twice the size of a basketball court (40 metres long and 18 metres high), and can be seen from a radius of up to 1.5 kilometres from the ground and 2.5 kilometres in the air.
The screens -collectively dubbed Lumen - are bigger than those that make London's Piccadilly Circus and New York's Times Square instantly recognisable. Lumen features the most advanced LED technology used on this scale making it a world first.
The newest addition to Johannesburg's skyline is indicative of Absa and Barclays' commitment to cutting-edge innovation technology* and urban regeneration.
Lumen follows the development of Absa Towers West, a five star green-rated building that is the head office of Absa and Barclays Africa and is the latest step in the Group's regeneration programme**.
The rejuvenation of the Absa campus will ensure an enhanced environment not only for customers and employees, but also for other businesses and entrepreneurs in the CBD. It also reinforces Absa and the wider Barclays Group's commitment to the City of Johannesburg and will make a significant contribution to the city's 2040 Growth and Development Strategy and its vision for a World Class African City of the Future.
Bobby Malabie, Absa and Barclays Africa Group Executive for Marketing, Communications and Public Affairs, says: "Africa is made up of some of most dynamic and fastest growing economies in the world. Our investment in Lumen is a vote of confidence in Johannesburg as one of the leading cities on the continent. We have committed to building and running the Go-To bank in Africa and we believe that Johannesburg is the perfect base from which to do so.
"Lumen is a significant step in a ten-year project that will regenerate and revitalise the Johannesburg CBD and supports Absa and the Barclays Group's fundamental value of Stewardship. This value is underpinned by the notion that no matter which realm we are active in, we will always leave things better than we found them. Supporting this notion, Lumen will become a landmark that will not only be instantly recognisable in Johannesburg, but on the world stage.
"As we progress and grow our business across the 13 African countries that we have operations in, Lumen will become the beacon from which we will share our stories of how we are helping people achieve their ambitions - in the right way."
Lumen employs energy-saving technology with LED tiles that boast the lowest power consumption in their class. To offset some of the carbon emissions on Lumen, Absa is building one of the largest rooftop solar photovoltaic farms on top of Absa Towers North in South Africa.
To offset the remaining carbon emissions Absa is also rolling out a programme run by Absa Insurance and Eco Navitas to subsidise solar geysers by 60% to more than 750 households This is the first time a programme to subsidise solar geysers has been launched in South African and represents a community investment of about R3.85 million.
