LED Street Lights from Osram Illuminate Austrian Towns
The Austian towns of Diex and Hörbranz have had street light fixtures made by EPS Soltec installed throughout the cities in a growing effort to emphasize the benefits of solar energy and lowering power consumption. The fixtures incorporate Golden Dragon Oval LEDs from Osram Opto Semiconductors.
The Osram LEDs were developed with a unique oval lens to direct the light more accurately onto the cities’ streets. The lenses distribute the light down at an angle of 80° x 120°. This lens and angle ensure that no light is lost sideways away from the path. If you look at your own town’s lights you will see that the usual circular distribution of light from conventional street lights is usually half wasted. The towns of Diex and Horbranz consider this reduction in light pollution a big plus.
EPS Soltec used solar power to run the LED lamps. The LEDs do not require secondary optics and can be integrated in almost any lighting design. The lighting can be dimmed and the color temperature can be adapted by combining white and yellow LEDs.
