Osram adds surface-mountable Oslon Black Flat S multi-chip LEDs for ADB and matrix headlights

Osram Opto Semiconductors GmbH of Regensburg, Germany has launched the Oslon Black Flat S series, which is claimed to be the first surface mountable LEDs with up to five individually controllable chips.

Due also to the contrast ratio (of 1:65) provided by the package, they are predestined for use in ADB (adaptive driving beam) headlights, says the firm. Switchable light segments enable oncoming traffic and traffic further ahead on the road to be masked out, making driving more comfortable and safer. With improved thermal properties, the new high-power LEDs offer system benefits and are suitable as an entry-level ADB solution even for vehicles in the compact class, adds the firm. The 3.75mm x 5.7mm x 0.43mm 3-chip version in the Oslon Black Flat S series has been available since October, and the versions with four chips (in a 3.75mm x 6.9mm x 0.43mm package) and five chips (in a 3.75mm x 7.9mm x 0.43mm package) will be available from January 2017.

Osram Opto says that the Oslon Black Flat S series represents a significant expansion of its LED portfolio in this area of application. For the first time the light-emitting surface of the powerful new chips does not require a recess for contact with the bond wire and produces highly uniform light across its square format, making it easier to adapt the optics. The chips are individually controllable and offer very high contrast between neighboring chips which is 100% verifiable. These features enable oncoming traffic and traffic further ahead to be actively masked out with a high degree of contrast, says the firm. Drivers benefit from the optimum distribution of light on the road at all times.

"The Oslon Black Flat S series enables the benefits of adaptive matrix light to be offered not just on flagship models but also on cars in the entry-level and compact classes," says product manager Thomas Christl. In addition to glare-free high beam, other adaptive LED front lighting functions such as cornering light and city light can be implemented, without the need for any mechanical elements.

ADB solutions for the entry-level segment

Up to now, only the Osram Ostar Headlamp Pro had individually controllable chips. The Oslon Black Flat S series now adds this feature to the portfolio. In addition, the chips are surface mountable and are compatible with standard processes. In contrast to the Oslon Black Flat, the Oslon Black Flat S LEDs have an optimized and symmetrical contact surface design which further improves heat removal and cycle stability. This combination of thermal management and standard processing reduces system costs, says Osram. The higher possible current load of up to 1.5A provides sufficient light on the road from only three segments, and produces as much as 2000 lumen from the 5-chip version.

The new multi-chip LEDs are being presented for the first time in booth 107 (Hall A3) at electronica 2016 (8-11 November) in the Munich Exhibition Center.
