Osram launches yellow Oslon Compact LED for vehicle front turn indicators

Osram Opto Semiconductors GmbH of Regensburg, Germany says that its new yellow Oslon Compact LED opens up new design options for turn indicators in vehicle forward lighting. With package dimensions of 1.5mm x 1.9mm x 0.7mm, the new version is small and yet so powerful that it is suitable for use in light guide applications. Based on indium gallium nitride (InGaN), the high-power LED offers output of more than 120 lumen even at high currents and application temperatures of 100°C (junction temperature, Tj, in the chip).

The yellow Oslon Compact is an addition to the two white versions of the Oslon Compact and is suitable for front turn indicators. Due to its compact design, it can be used in particular to create light guide solutions. Light guides themselves measure less than 10mm 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 (DRLs), the new Oslon Compact is suitable especially for light guide solutions, just like the other members of the product family,” says Andreas Geistreiter, marketing LED Automotive at Osram Opto. “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.”

The yellow light from the new LED is not generated directly but by ceramic conversion from a blue chip (C2 technology). This, in combination with UX:3 chip technology, is behind the Oslon Compact’s high output and thermal stability – especially at high currents and temperatures. At room temperature and 700mA, the LED achieves a typical brightness of 140lm. At application temperatures of 100°C (Tj) the Oslon Compact still achieves 120lm.
