ams OSRAM Presents New Quantum Dot LED

Quantum Dots (QDs) are special semiconductor particles that emit light in different wavelengths de- pending on their size when blue light hits them. Their unique properties allow very precise adjust- ment of the desired color temperature and outstanding efficiency values in the warm white color spectrum. "With our specially developed Quantum Dot phosphors, we are the only manufacturer in the market that can offer this technology for general lighting applications," said Peter Naegelein, Di- rector Product Management Illumination at ams OSRAM. "The Osconiq E 2835 is also the only available LED of its kind in the established 2835 package and impresses with extremely homogene- ous illumination."

The Osconiq E 2835 CRI 90 (QD) is available in a color temperature range of 2200 to 6500 K and achieves outstanding efficiency values of over 200 lm/W. The space-saving dimensions of the 0.5 W component of 2.8 mm x 3.5 mm enable particularly compact and efficient luminaire designs. The good absorption behavior of the Quantum Dots reduces the amount of nanoparticles required. Un- like other phosphors in general lighting, Quantum Dot-based solutions are still in their infancy in terms of development – with a very promising future of what can be achieved in upcoming product generations. A special feature of Quantum Dots from ams OSRAM is that they are encapsulated in a protective package that makes them more robust, protecting them from moisture and other exter- nal influences. This special encapsulation technology makes it possible to use the small particles in demanding "on chip" operation within an LED.
