Philips' New Solar LED Street Light Saves Even More Electricity
Street lighting electricity consumption is significant and a major challenge in
an increasingly carbon-constrained world where electricity prices from
traditional sources will continue to skyrocket.
According to the City of Sydney, in 2008/09 the 20,000 street and park lights across the City
racked up a $3.5 million electricity bill; sparking the council to trial LED
LED street lighting offers anywhere from 50 - 80% in electricity savings. Throw
a solar panel
on an LED street lamp and the savings; both financial and environmental in terms
of emissions, are even greater.
Like other aspects of LED lighting, LED street lamp technology is rapidly
evolving. Philips recently announced what it claims to be the world’s most efficient and cost effective solar powered LED street lighting solution
based on each kilometre of roadway.
The company's latest Solar Gen2 solution allows for a lamp post spacing of up to 50 meters, much wider than with other solutions,
and an integrated solar panel that can feed clean electricity to the mains grid
during the day; offsetting consumption at night. The system also includes a
battery storage system, for true off grid applications.
Central to the Solar Gen2 is combination of new High Brightness LEDs along with
patented optics. The system incorporates an intelligent charge controller, developed by NXP Semiconductors
N.V., which maximizes battery life. Light levels can be dimmed based on a self learning intelligence and a history log.
Also incorporated is Philips LEDGINE, which allows LED modules and drivers to be
easily replaced and upgraded; future-proofing the system.
"By making Solar Gen2 as power efficient as possible, we’ve produced
something which is genuinely groundbreaking while remaining affordable in those
countries that can benefit the most from it. Harnessing the energy of the sun as
effectively as possible means reduced electricity demand and a more robust
infrastructure," says René Penning de Vries, CTO of NXP Semiconductors.
Philips sees Solar Gen2 particularly beneficial to towns and cities close to the
equator and says if used in rural areas it can help improve the lives of an estimated 1.6 billion people
without access to conventional electricity.
Philips will be focusing rolling out its Solar Gen2 street lighting
solution in South East Asia, Africa, China, India and North America.
