LEDs by Seoul Semiconductor lighten the anniversary installation at the Roman Forum

April 21, 2011
Date Announced: 21 Apr 2011 Rome immerses his birthplace in new light. Before the birth of Christ the Romans built two temples among the seven hills of Rome, at the latest with the construction of these temples the Forum Romanum was born, considered as the centre of political, economic and cultural life. After the Forum Romanum has literally seen a dark era, a LED light installation now illuminates the buildings on the occasion of its founding anniversary.The eternal city has a new, old attraction: as part of the celebrations for the 2762. Founding day of the "eternal city" the city fathers decided to illuminate the Roman Forum in noble light again: A modern LED illumination has one of the major attraction of Italy shine in a new light.Staging at nightThe light installation was designed by the architecture firm Terzi & Annunziata from Rome on behalf of the order of the Roman Superintendenture for cultural heritage. The technical part was executed by the Italian company DTS. "We started with the installation of the light elements in early April 2009 and finished it on time on 20th of April," recalls Silvano Latteo, President of DTS. "A total of 55 light units from different series are used, all of them with LEDs by Seoul Semiconductor because of their high reliability, great efficiency and excellent colour homogenity. Most of the lights were installed on the ground, but some as well in 35 meters height at the Column of Trajan. We have placed particular emphasis on the use of the light elements in such a way that they form a link between the various monuments. The lamps consist of a number of combined, small light units: LEDs (Light Emitting Diodes). Therefore, different colour shades can be combined which intensify the atmosphere of the buildings. Considering the light systems that have been installed at the Roman Forum this means 36 LEDs have been combined in one case: 24 white diodes are augmented with twelve amber diodes in order to create a warm lighting. Thanks to modern technology, the color temperature can be selected between 3200 and 5600 Kelvin. In comparison to the sun: according to the international norm medium sunlight has 5500 Kelvin. Eco-friendly lighting systemsThe Korean company Seoul Semiconductor supplied the LEDs to illuminate the Roman Forum: “For the Roman Forum we use the light units P4 diodes from our Z-Power Series. The high durability and low energy consumption are an ideal basis for a permanent lighting," said Manuel Zarauza, Managing Director at Seoul Semiconductor. "The LEDs are also free of toxic substances like mercury and emit no harmful infrared or ultraviolet rays."Thanks to these specifications the diodes used in Italy meet the Restriction of Hazardous Substances (RoHS). In addition to the non-lead implementation this directive also means that no other contaminants such as cadmium, mercury, chromium and brominated flame retardants are used either - a fact not only welcomed by the industry association BITKOM, but also by the environment.Advantage of the LED: durabilityLEDs are generally more durable than conventional incandescent bulbs: The life of LEDs exceeds the conventional bulbs by a factor of 130. Although, this impressive life-time will not be sufficient to light the city that is supposed to live forever at least as long as people live but continuous operation is possible for more than eleven years, based on a calculation of lighting of 24 hours per day; a value which is impossible to achieve with conventional light bulbs. Moreover, the diodes emit more than five times as much light per watt. Compared to filament lamps, LEDs save up to 86 percent of energy. It was no coincidence that DTS has chosen Seoul products for its lights, according to Latteo: "We have a long and successful relationship with Seoul Semiconductor. The company has extensive experience in providing innovative technologies.” Following the successfull project on the Forum Romanum both companies have extended their cooperation with the lighting of the historical Basilica di San Pietro fuori le mura. In fact the technology from the Korean manufacturer has been used for an extensive list of lighting spectacles so far. Among other prestigious projects, Seoul Semiconductor LEDs were used to light the Eiffel Tower in Paris as well as the Olympic Games 2008 in Beijing. At the 16th Asian Games 2010, Seoul Semiconductor LEDs provided the right light for the opening ceremony. By the way Rome and Seoul have been connected for the last eleven years not only through technology, but as well through a city partnership (since 18th of March 2000). If the LEDs at the Roman Forum had been installed at the beginning of the partnership, they would still glow in continuous operation for the anniversary that has just been celebrated.About Seoul SemiconductorAccording to the 2011 LED market reports issued by IMS Research in the U.K. and Strategies Unlimited in the U.S., SEOUL SEMICONDUCTOR is the world’s fourth largest LED supplier, holding more than 6,000 patents.
