White lighting LEDs
21 March 2012, Opto-Electronics
With its new generation of Oslon SSL LEDs, OSRAM Opto Semiconductors has improved performance and efficiency. Additionally, the luminous flux of the LED at elevated temperatures has now been stabilised. In doing so, it is possible to retain a virtually constant luminous efficacy, despite high application temperatures. Thanks to this optimisation, luminaire design is significantly simplified.
The LED provides a luminous flux of typically 98 lm in warm white (3000 K), with an operating current of 350 mA at an application temperature of 85°C in the chip. With its typical luminous efficacy of 96 lm/W, referring to the ratio between luminous flux and expended electrical output, it is among the most efficient 1 mm² chip LEDs presently on the market.
The combination of higher luminous flux and reduced forward voltage of 3,1 V equals an efficiency increase of approximately 25%, when compared with the previous generation.
The new Oslon SSL LEDs are available in warm white (3000 K) suitable for interior lighting (type EC), for instance in downlights, as well as in cold white (5000 K) for use in exterior lighting (type PC). As with the previous products in the range, the new arrivals are available in the small component size of 3 x 3 mm and offer two different lenses. Thanks to the reflectivity of the package, the light that is irradiated to the side or to the back is reflected and can be used again.
