Ultra-compact yellow LED for extreme demands in headlamps
The yellow Oslon Compact LED from Osram immediately opens up new design options for turn indicators in vehicle forward lighting. With package dimensions of 1.5 mm x 1.9 mm x 0.7 mm the new version is so small and yet so powerful that it is ideal for use in light guide applications. This high-power LED, based on indium gallium nitride (InGaN), offers extremely impressive output of more than 120 lumen even at high currents and application temperatures of 100° C (Tj in the chip).
The yellow Oslon Compact is an addition to the two white versions and is ideal for front turn indicators. Thanks to its compact design it can be used in particular to create light guide solutions. Light guides themselves measure less than 10 mm in diameter so the LEDs have to make full use of the available area by being packed very close together. "For turn indicators or daytime running lights, the new Oslon Compact is suitable especially for light guide solutions, just like the other members of the product family", said Andreas Geistreiter, Marketing LED Automotive at Osram Opto Semiconductors. "Thanks in particular to its high luminous efficacy and compact size it represents a further step in the direction of miniaturization and greater freedom of design, opening up such possibilities as quasi-3D effects. This special design element is of huge interest in the premium automotive segment, and thanks to the new Oslon Compact it is now easier for set makers to achieve."
Plenty of light – even at application temperatures of 100° C in the chip
The yellow light from the new LED is not generated directly but by ceramic conversion from a blue chip, known as C² technology. This technology, in combination with UX:3 chip technology, is what is behind the exceptionally high output and thermal stability of the Oslon Compact – especially at high currents and temperatures. At room temperature and 700 mA, the LED achieves a typical brightness of 140 lm. At application temperatures of 100° C (Tj in the chip) the Oslon Compact still achieves the impressive figure of 120 lm.
