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

CommCurrently, LED tube lighting, LED spotlight fixture feeding tube and the
volume of production of led downlight
other little has been achieved.unities 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. Nova Scotia, meanwhile, has performed 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, “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,China Merchants Securities researcher appear

business development is the LED lighting tube, said: "At present,
the target has entered a stage of maturity, LED t5 tube applications directly in
the existing areas have a high penetration rate, therefore, for companies to get
the development needed to show tube LED light tube and five areas of
development. 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, “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,Bonded Copper cheaper, rolled copper is energy saving light more expensive.

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.solder joint is not smooth,
LED R4ds packaging is ruined, etc.), and
second, static protection is not good, a lot of LED chip is breakdown, lead to
micro-light or when power is off phenomenon.

Pielenhofen plans to
upgrade to LED street lighting across the entire community in stages. Indeed
European Union (EU) regulations will give 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.
