Osram Opto’s Oslon SSL LEDs used in BEKA’s new LEDlume street-lighting luminaires

Osram Opto Semiconductors GmbH of Regensburg, Germany says that its Oslon SSL LEDs are being used in all variants of the LEDlume, the latest family of luminaires from street-lighting maker BEKA (Pty) Ltd of Johannesburg, South Africa, which are designed to improve the energy efficiency and durability of lighting in the streets of the African continent.

In 2010, BEKA equipped its luminaires for the World Cup stadia in South Africa with LEDs supplied by Osram Opto. For the new LEDlume street lights, Oslon SSL LEDs are particularly compact, with housing dimensions of 3mm x 3mm, enabling a large variety of design possibilities. With a light colour of 4500K and a color rendering index (CRI) of 70, the luminaires ensure aesthetically pleasing light conditions on the streets of Africa, it is claimed.

A benefit of the LED street lighting is the high efficiency of Oslon LEDs, which yield more than 100lm/W at a drive current of 350mA. As a consequence, the BEKA LEDlume uses about 50% less energy than the existing technology. The BEKA LEDlume can also be optionally furnished with Osram Opto’s SFH5711 ambient light sensor, 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 on or off, more energy can be saved.

The BEKA LEDlume is available in versions ranging from 16W to 90W power consumption, incorporating 12-60 Oslon SSL LED per luminaire ired. The street lights thus comply with the specific requirements of the African continent. For example, the 12V and 24V versions are also suitable for operation with solar power. The special thermal conditions of the continent have also been taken into account: the luminaires are designed for ambient temperatures of 35 degrees Celsius 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 so that, once the service life of the luminaire has expired, it will still generate more than 80% of the original brightness.

“The consistently high quality of our products, as well as our good relationship with BEKA, is what this project and many other joint projects have been based on,” comments Ryan Hunt, country manager at Osram Opto Semiconductors in South Africa, on the renewed co-operation with BEKA.
