Outdoor Lighting: Pielenhofen installs Osram LED

Outdoor
Lighting: Pielenhofen installs Osram LEDs, Nova Scotia expands SSL program

Communities across North America have been making the biggest headlines for
LED street-light retrofits, but even small communities around the globe are
making the switch as evidenced by an outdoor lighting project in Pielenhofen,
Germany. Herkules Elektronik GmbH retrofit kits that use Osram’s Golden Dragon
Oval Plus LEDs are lighting a new home community and a larger conversion is
planned.Light up the architecturally table

significant solid-state-lighting (SSL) retrofits and plans to convert every
light in the country in five years.
Pielenhofen SSL-lit neighborhood

Pielenhofen first tested LED street lights in February 2010 with two
luminaires installed in the heart of the community. The community has now kicked
off a transition to LEDs with the installation of nine SSL fixtures in a
neighborhood called Rohrdorf. Moreover the community is using adaptive controls
to maximize energy consumption.

Local mayor Reinhold Fersti noted the
superior ability of the luminaires to control beam pattern as one reason for the
conversion. Fersti said,Although this article shows that Cree's led lighting and Philips LED product
sales are not equal it is important to note that Philips LED salesWhile using
compact fluorescent light bulbs energy saving
light helps conserve energy, it is important that the bulbs are collected
and recycled properly to protect our environment “What convinced us was the
modern technology, as it not only produces more pleasant, warm light: the light
diodes only project their light into the desired direction.”

The
Herkules luminaire retrofit was developed as a replacement for mercury-vapor
lamps and the 50W koffer-type housing that is widely used in the city of Kassel,
Germany. Indeed Herkules refers to the design as a Kassel-type retrofit, and the
26W kit includes the light engine and driver electronics that replace the lamps
in existing housings.
The design relies on the Golden Dragon Oval Plus LEDs
to form the beam pattern. The LEDs feature an integrated oval lens that can
spread the beam in a somewhat rectangular pattern along a roadway, with minimal
light trespass. For more information on the LEDs and beam patterns see, “SSL
luminaires must deliver reliable beam patterns in outdoor applications."



About the beam qualities of the components and the Kassel retrofit,
Osram said,Under efforts of led
spotlight boosting the viability of LED luminaires, many companies are
expanding high-power selections. “This effect is reinforced by the integrated
lens of the Golden Dragon Plus: this makes it possible to generate a brighter
and more even illumination of a defined area, despite low intake of power – it
also achieves an optimum illumination of the street, conforming with the
relevant norms, avoiding scattered light and staying below the limit regarding
dazzle.”

Adaptive controls and dimming

Based on the LED
retrofit, Pielenhofen would realize what’s essentially 50% energy savings based
on the lower-power kits, but the savings will actually be greater because the
community is using dimmable SSL technology. The dimming functionality was proven
out in the Kassel retrofit last year where late at night the power consumption
is further reduced to 14W per fixture.

Pielenhofen plans to upgrade to
LED street lighting across the entire community in stages. Indeed European Union

have improved greatly with recent updates. such communities little choice going
forward. Beginning in April 2012, the sodium vapor lights presently used by
Pielenhofen will be taken off the market. The retrofit kits will provide a way
to replace failed lamps.

The EU is also mandating the removal of mercury
vapor lights beginning in April 2015. Communities across the continent will be
faced with replacement or retrofit scenarios.
