ams OSRAM’s third generation of OSLON Submount PL LEDs boosts brightness in automotive forward lighting
ams OSRAM GmbH of Premstätten, Austria and Munich, Germany has launched the next generation of its OSLON Submount PL family of LEDs, offering higher brightness and more design flexibility to manufacturers of automotive forward lighting modules and products.
Based on internal data, the third-generation OSLON Submount PL LEDs are about 9% brighter than the second generation, giving automotive manufacturers the potential to reduce the system cost of new headlamp designs. With the introduction of the new Gen3 products, the OSLON Submount PL family is expected to maintain its strong market position in standard static headlamps for entry-level vehicles and electric vehicles.
The OSLON Submount PL Gen3 family features variants with one of two options for the light-emitting area (LEA), giving headlamp makers the flexibility to meet different customer specifications in a product with a single board layout:
- the (1030 μm)2 LEA option provides a balance between high luminance and high efficacy;
- the (1150 μm) 2 LEA option is optimized for efficacy.
‘These new LEDs are equally applicable to static headlamp designs, in which the light source is mounted directly on the heatsink, eliminating the need for a high-performance PCB, and to standard modules, in which the LED is mounted on an open-frame housing,” says Philipp Puchinger, product marketing manager for Automotive Forward Lighting. “In both cases, the introduction of the latest generation of OSLON Submountv PL LEDs gives automotive manufacturers a roadmap to higher efficacy and lower system costs.’
The new LEDs maintain the characteristics of quality and value offered by earlier generations of the OSLON Submount PL product line, says the firm. They are supplied in tightly specified single-color bins, enabling manufacturers to streamline their inventory and to simplify the assembly process. The LEDs also offer high thermal stability and a uniform beam pattern characterized by homogeneous color-over-angle radiation.
The OSLON Submount PL Gen3 products are available for sampling now with a (1030 μm) 2 LEA. The part numbers are KW2 C2LNL3.TK (two-chip module) and KW3 C3LNL3.TK (three-chip module).
Versions with a (1150 μm) 2 LEA will be available for sampling from December. Part numbers are KW2 C2LPL3.TK (two-chip module) and KW3 C3LPL3.TK (three-chip module).
