Lighting in Design November-December 2015

2015 is the International Year of Lighting and Bres- cia, a city in northern Italian, has undertaken an energy savings project, replacing all the traditional lamps in public lighting with LEDs. The project should be completed within 2016. In what is a standout success for AEC, ITALO luminaires have become a benchmark in public lighting and over 16 000 Italo luminaires have been specified for Brescia, which will turn into a Smart City. AEC is well known for its technical proficiency, and the company’s extraordinary production set- up has contributed to this latest success since completely automated assembly lines guarantee quick response times. Brescia covers an area of 90.34 km 2 and has about 195 500 inhabitants. At present, the city consumes more than 18 million kWh of electrical energy each year. With new LED lights, the city forecasts a 40% reduction in annual energy con- sumption, leading to savings of around € 8 million for municipality coffers in just 10 years. Opto Semiconductors has added the Soleriq L 38 filament LED to its product range. The long thin shape of the LEDs provides the basis for filament lamps which, in terms of their appearance and emissions characteristics, aremore than a match for their incandescent lamp predecessors. Soleriq LEDs offer uniform colour appearance and a quality of light that is ideal for aesthetic lighting applications. Each Soleriq L 38 has a length of 30 mm and a diameter of 1.8 mm. This shape, which is similar to that of a conventional filament, plus an emis- sion angle of 360 ° and an excellent quality of light, Filament LEDs from Osram

LED lighting means greater efficiency and savings. In addition, LED lamps have a longer life cycle leading to fewer damaged lamps and less maintenance. The city has calculated that every year fewer than 2500 lamps will get burnt and less than 10 000 will be replaced. Energy efficiency, longer life cycles and reduced maintenance costs impact on the environment. A 40% decrease of consumed energy every year leads to a reduction of carbon emissions. LED lon- ger life will also avoid the production of more than 1.5 tons of RAEE (electric and electronic waste) every year. The replacement of the old lamps will remove any mercury trace and other polluting substances according to reference standards. Last but not least, ITALO’s state-of-the-art optics will guarantee a better lighting for citizens’ safety.

The Soleriq L 38 offers high brightness. It is available in three versions with 90, 130 or 140 lu- men (lm). These values enable all previous lamp wattages up to 60W to be replaced with equivalent LED filament solutions. The driver voltage needed for the LED filament lamps can also be adjusted. All versions have an extremely high luminous ef- ficacy of 150 lm/W and provide warm white light (2500 to 4000 Kelvin). Thanks to the good colour rendering index of over 80, the Soleriq is ideal for indoor lighting.

makes it perfect for use in LED lamps of all wattages that mimic the appear- ance of classic light bulbs. Soleriq L 38 LEDs are offered in different MacAd- am* groups according to their colour, forward voltage and brightness – at a temperature of 85°C, which closely
