Osram Opto Semiconductors GmbH of Regensburg, Germany has launched the Oslon Black Flat S series, which is claimed to provide the first single-LED solution for adaptive front-lighting systems (AFS) in vehicles. AFS enables the direction of the light beam to adjust when cornering for example, providing optimal visibility by illuminating the side of the road in addition to in front of the vehicle. This also protects oncoming traffic from glare through the adaptive driving beam (ADB).
The Oslon Black Flat S series is claimed to comprise the first surface-mountable LEDs with up to five individually controllable chips. Switchable light segments enable oncoming traffic and traffic further ahead to be masked out, making driving more comfortable and safer. With their improved thermal properties, the high-power LEDs offer system benefits and are suitable as an entry-level ADB solution even for vehicles in the compact class, reckons the firm.
“Increasing visibility and reducing glare, adaptive front-lighting systems like Adaptive Driving Beam enhance safety and comfort for both drivers and traffic participants,” says product manager Thomas Christl. “ADB is one of the most advanced AFS developments. Drivers virtually drive with an always-on high-beam light distribution while other drivers on the road only experience low-beam glare,” he adds. “With camera integration, ADB detects other vehicles or obstacles and either dynamically shadows out these vehicles in order to prevent glare or illuminates these obstacles to ensure safety.”
The Oslon Black Flat S combines benefits from both the Oslon Black Flat package and Osram Ostar Headlamp package. Featuring Osram Opto’s new chip technology with notchless chips, optical design can be simplified and further brightness improvements are made possible, says the firm.
The Oslon Black Flat S has an optimized layout of thermal pads that help to dissipate heat effectively, ensure light homogeneity and further improve second level reliability. As an surface-mount (SMT) package it is possible to integrate these new functionalities and improved features easily and cost-efficiently using standard SMT processes, claims the firm.
