ams OSRAM launches new quantum dot LED to redefine high-end lighting

• Osconiq E 2835 CRI 90 (QD) expands ams’ portfolio of lighting solutions, offering outstanding quality performance in the new mid-power LED;

• Adopting proprietary quantum dot technology, the efficiency is outstanding, even at high color rendering index (CRI), it can guarantee efficiency of more than 200 lm/W;

• The world’s first 2835 packaged LED using mature quantum dot technology.

ams AG (SIX: AMS), a leading global supplier of optical solutions, today announced the launch of a new quantum dot LED, the Osconiq E 2835 CRI 90 (QD). LED technology has been evolving over the years, and the demand for high-quality, energy-efficient general lighting solutions is increasing. Manufacturers have been working hard to develop LEDs that meet this requirement, and ams is no exception. The Osconiq E 2835 CRI 90 (QD) pushes efficiency values ​​to new heights and maintains excellent efficiency even at very high color rendering indices and warm light colors. The special 2835 package brings further system advantages to luminaire manufacturers.

Quantum dots (QDs) are special semiconductor particles that emit different wavelengths of light when exposed to blue light, depending on their size. Due to their unique properties, they can be very precisely tuned to achieve the exact color temperature required, with excellent efficiency in the warm white spectrum. "We have specially developed quantum dot phosphors and are the only manufacturer on the market that can offer this technology for general lighting applications," said Peter Naegelein, Director of Product Management at OSRAM Lighting at ams. "The Osconiq E 2835 is also the only LED in its class to come in the proven 2835 package, which gives it an even, high-quality illumination that is astonishingly uniform."

The Osconiq E 2835 CRI 90 (QD) is available in a range of colour temperatures from 2200K to 6500K with an outstanding efficacy of over 200lm/W. With a power of 0.5W and a size of 2.8mm x 3.5mm, its small size facilitates compact and efficient lighting designs. Quantum dots have good absorption properties, thus reducing the number of nanoparticles required. Unlike other phosphors in general lighting, the development of quantum dot solutions is still in its infancy, but the future generations are promising. A unique feature of ams OSRAM’s quantum dot solutions is that they are protected by encapsulation, making them more robust and less susceptible to moisture and other external factors. Thanks to this special encapsulation technology, it is possible to use such tiny particles in the demanding “chip-scale” operation within the LED.

The LED also meets the strict requirements for light source efficiency in the Single Lighting Regulation (SLR), which will become mandatory in Europe in September 2021. Among other requirements, the new regulation requires a value of >50 for saturated red, the so-called R9 value. R1 to R8 are used to determine the CRI, with each R value representing a specific color.

Osconiq E2835 is also available in two other versions: a CRI 80 component for office and retail lighting solutions and Osconiq E2835 Cyan. Among them, Osconiq E2835 Cyan can produce a spectral peak in the blue light wavelength range, thereby suppressing the production of melatonin in the human body, making it ideal for human-centric lighting solutions.

The Osconiq E 2835 CRI 90 (QD) expands ams’ comprehensive portfolio of high-quality lighting solutions.
