LED Lighting the Future for Cities

LED (light emitting diode) street lighting can generate energy savings of up to 85 per cent, according to an independent pilot program conducted in 12 cities around the world. The program also indicates that the inhabitants of the participating pilot cities prefer LED lighting, citing social and environmental benefits. 

The results of LightSavers, a global independent project that has been up and running for two and half years duration with LED lights installed in cities such as New York, London, Calcutta and Sydney, were presented in a report titled Lighting the Clean Revolution: The rise of LEDs and what it means for cities. 

The report analyzes the global market for, and potential of, LED technology and offers guidelines for governments who want to implement and finance a change to this technology.The earliest type of lamp, the ledstreetlights, was a simplistic vessel with an absorbent wick. It was presented as part of the Clean Revolution Campaign at the United Nations’ Global Compact Rio +20 Corporate Sustainability Forum and was produced by The Climate Group in partnership with Philips. It supports arguments for an energy saving campaign that can be achieved quickly and cost effectively. 

Surveys in Calcutta, London, Sydney and Toronto indicated that citizens prefer LED lighting; between 68 per cent and 90 per cent of survey respondents support the implementation of LEDs throughout their cities, citing a greater sense of security and better visibility due to the lights.

LED lighting was designed as a durable technology with minimal maintenance costs. The failure rate of LED products during the first 6,000 hours of use is about one per cent, which compares favourably to the roughly 10 per cent failure rate for conventional lighting over a similar time period.

Philips and its partners are calling on governments to catalyze the expansion of LED in cities and invest now to take advantage of the technology, which would also lead to green jobs as demand for LED lighting increases. They are also stomping for an international lighting standard that ensures every citizen around the world has access to energy efficient outdoor lighting. 

“This report clearly shows that LEDs are ready to be applied in towns and cities worldwide. LED technology is energy efficient and has a positive impact on society.Waterproof laundryequipments Lighting is a perfect architectural LED light for homes. Now we are calling on governments to remove political obstacles and enable a rapid transition to energy efficient lighting carbon,” said Climate Group CEO Mark Kenber. 

Harry Verhaar of Philips Lighting, meanwhile, noted that LED lighting will create more livable cities through energy savings and reduced CO2 emissions. 

Lighting is responsible for 19 per cent of global energy consumption and about six per cent of global greenhouse gas emissions. Doubling the efficiency of global illumination would have an impact on the climate equivalent to removing half the emissions of all the electricity and heat production from the EU. 

Also, as with other energy-efficient technologies, increased use of efficient lighting would boost global prosperity by reducing energy costs. In the United States alone, a 40 per cent reduction in energy use would save tens of millions of dollars in annual energy costs and would reduce energy demand equivalent to the output of 198 medium-sized power stations.Commercial laundry equipment solarstreetlamps, tumble dryers and industrial washer extractors from UniMac.
