New conversion technology delivers outstanding efficacy even at high
color rendering indexes with the Osconiq S 3030 Quantum Dot
Opto Semiconductors, a world leader in the optoelectronics
industry, will showcase its first Quantum Dot LED in booth #1701 at LIGHTFAIR
Dots (QD) are nanometer-sized semiconductor particles and are
approximately 10,000 times smaller than the diameter of a human hair.
Due to their very small size, the light that is re-emitted when blue LED
light hits the nanoparticles depends on their size. For example, QD
particles that are roughly three nanometers in size produce green light,
while particles around seven nanometers emit red light. This innovative,
tunable light conversion technology is featured for the first time in
Osram’s Osconiq S 3030 QD mid-power LED. It will lead to more QD LEDs
for the general lighting market in the future. The Osconiq S 3030 QD was
specially developed to enable customers to design luminaires with high
efficacy and excellent color rendering for area lighting and downlight
When manufacturing conventional white LEDs, the main objectives are
efficacy and product quality. Achieving both at the same time is
particularly challenging, especially with very high color rendering
indexes (CRI). QDs can solve this problem. The great advantage of using
these nanoparticles is that the existing LED manufacturing processes
remain the same. QDs are simply used instead of conventional phosphors
when the converter material is applied.
More than a year ago, Osram acquired Pacific Light Technologies (PLT), a
leading company in the development and manufacturing of high-performance
optical nanomaterials. The PLT QD technology enables Osram to begin to
close the efficacy gap that exists between CRI 80 and CRI 90 LEDs today.
The new Osconiq S 3030 includes a specially developed QD phosphor
solution that enables CRI 90 to achieve an outstanding efficacy value of
173 lm/W at 3000 K – a best-in-class value for 0.2 W high-performance
LEDs. The compact dimensions of 3.0 mm x 3.0 mm and the low thermal
resistance enable simple system design. The Osconiq S 3030 QD is also
available in various color temperatures from 2700 to 6500 K.
Another unique feature of the PLT QD technology is that the Quantum Dots
are encapsulated to protect them from moisture and other external
influences that pose the greatest risk to the functionality of an LED.
The special encapsulation technology allows the QDs to reliably master
the demanding conditions of on-chip operation within the LED component.
EdisonReport recently announced that the Osconiq S 3030 QD is a Top 10
MUST SEE item at this year’s LIGHTFAIR International in Philadelphia.
The product, along with other Osram lighting technologies, will be shown
in booth #1701.
