Osram launches new generation of Oslon Compact PL and Oslon Black Flat S LEDs

Osram Opto Semiconductors GmbH of Regensburg, Germany says that, through significant leaps in their performance, the latest versions of its Oslon Compact PL and new versions of its Oslon Black Flat S LED product families are targeted at further increasing the market penetration of LEDs in headlights (both high-beam and low-beam).

In a few years, LEDs will be the predominant light source in car headlights, since their compactness and energy efficiency in particular are major advantages over conventional technologies, says Osram Opto. LEDs also make it easy to achieve the brightness values required by manufacturers. In recent years, technical advances have contributed to the increasing popularity of LED-based headlamps. Due to their compact dimensions, LEDs allow enormous freedom in design. Now LED makers are looking to improve the already very high level of quality, in terms of brightness, energy efficiency and thermal performance.

Osram Opto is hence launching a new generation of 1- to 4-chip versions in the Oslon Compact PL product family. Like their predecessors, the ceramic components have an electrically insulated pad that makes it much easier to dissipate heat from the package. Higher current is therefore possible, which allows the 1-chip version to achieve a brightness of 395lm at 1A with a chip area of 1mm2. Due to the very small dimensions of 1.9mm x 1.5mm x 0.73mm, the product is suitable for ADB (adaptive driving beam) systems and in extremely space-saving system designs.

In addition, the Oslon Black Flat S family has been expanded to include 1- and a 2-chip versions. The special lead-frame-based components feature a high contrast values (>1:200) and very low thermal resistance, allowing for higher currents. The 1-chip variant reaches a brightness of 395lm at 1A. The square lighting surface of the UX:3 chip makes optical design particularly easy for headlight manufacturers, claims the firm.

The different technology concepts of the Oslon Black Flat S and Oslon Compact PL enable users to choose the best possible combination of LED and PCB for their systems, says Osram Opto. Due to the luminous efficiency values of up to 130lm/W at 1A, headlights with smaller heatsinks or even without heatsinks are conceivable in the future, leading to a potential reduction in system costs.

“LEDs such as the Oslon Compact PL and the Oslon Black Flat S will lead to an increasingly high penetration rate in vehicles, including small- and mid-sized cars,” reckons Florian Fink, marketing manager Automotive Exterior at Osram Opto. “We always work in close cooperation with our customers to constantly improve our established product families and to push the limits of achievable brightness values even further in future,” he adds.

The package dimensions remain the same in the new product generations of the Oslon Compact PL and Oslon Black Flat S, allowing headlamp manufacturers to exchange the products.
