Oslon Compact LED permits unique, signature headlight design using smallest high-power LED available
Osram Opto Semiconductors announces the prototype of the Oslon Compact, currently the smallest high-power LED available to the automotive market. A prototype is being unveiled at the SIA Vision 2012 Conference in Versailles, France (October 9-10).
ThanOne LED for all designs
Now, the extremely small size of the new Oslon Compact, combined with its high light output, enables a single LED type to be used as the default light source for all automotive forward lighting applications. The light points in the headlight can be placed in any arrangement, for example, and customized designs can be developed to give different vehicles a unique appearance. The small size of the Oslon Compact LEDs means they can be grouped very close to one another so they can even be used for light guide solutions and adaptive front lighting systems (AFS).
Reducing LED design to the bare essentials
This compact design has been achieved by reducing the LED to its bare essentials. The entire LED package is not much larger than the actual light-emitting surface of the chip. The platform is Osram Opto Semiconductors’ ThinGaN UX:3 chip technology, which involves transfer to a silicon carrier and removal of the original silicon substrate to provide high luminous efficacy even at high currents. The prototype showcased at SIA-Vision measures only 1.5 x 1.9 mm² and produces 200 lumens from 700 mA. The clear white light from the chips is achieved through OSRAM’s C2 technology which converts blue light with the aid of ceramic conversion.
The solution the market demands
“The development of the Oslon Compact is a direct response to changing market requirements in the automotive sector, where there is a need for high-power LEDs that are more compact and more cost-effective than previously,” said Mike Godwin, Director Visible LEDs. “We have been able to adapt the reliable chip and package technologies that have proven so successful in the Oslon Black Flat and Ostar Headlamp Pro LEDs to fit this smaller design so that we can supply the market with the solution it requires.” The introduction of this space-saving solution makes a substantial contribution to the adoption of LED technology in the forward lighting sector and makes these efficient and durable lighting solutions available as standard for more vehicle models – not just in the high-end sector.
