OSRAM LEDs power SA street lights
23 November 2011
News
BEKA has launched its latest range of street lighting products, under the brand name LEDlume, which take advantage of LED technology supplied by OSRAM Opto Semiconductors. All variations of these luminaires are equipped with Oslon SSL LEDs and are designed to improve the energy efficiency and durability of lighting in streets across the African continent.
Oslon SSL LEDs are particularly compact, with housing dimensions measuring 3 by 3 mm, and thus enable a great variety of design possibilities. With a light colour of 4500 K and a colour rendering index (CRI) of 70, the luminaires ensure pleasant street lighting conditions.
An additional benefit of the modern LED street lighting is the high efficiency of Oslon light diodes – their light yields more than 100 lm/W at 350 mA. As a consequence, the LEDlume uses approximately 50% less energy than legacy technology. Optionally, the street light can be furnished with the ambient light sensor SFH5711, also from OSRAM, which automatically adapts the brightness of the luminaires to the ambient light or to customer-specified preferences. Thus, by dimming or intelligent switching of the luminaires, even more energy can be saved.
BEKA’s LEDlume is available in numerous versions, ranging from 16 to 90 W power consumption. Depending on the version, between 12 and 60y Oslon SSL LEDs per luminaire are required. Thus, the street lights comply with the special requirements of the African continent. For instance, the 12 and 24 V versions are also suited for operation with solar power.
Furthermore, the thermal conditions of the continent have also been taken into account: the luminaires are designed for ambient temperatures of 35°C, and as a result, in spite of the high temperatures, the durability of the LED is not affected. Lasting more than 50 000 hours, the average durability of the LED also complies with the L80 standard. This means that once the service life of the luminaire has expired, it will still generate more than 80% of the original brightness.
