ams OSRAM launches third generation of OSLON Compact PL LEDs
ams OSRAM GmbH of Premstätten, Austria and Munich, Germany has introduced the third generation of its OSLON Compact PL family of automotive LEDs, boosting brightness by 8% from the second generation. By producing the luminous output required by safety specifications with fewer LEDs, the new LEDs are said to offer manufacturers of automotive forward lighting greater value and new design options.
As compact LEDs housed in a robust ceramic package, the OSLON Compact PL products are a common component of forward lighting assemblies across all segments of the automotive market, from budget to premium. ams OSRAM has supplied about 100 billion LEDs in vehicles since 1990. OSLON Compact PL products are said to provide reliable, standards-compliant light output for high- and low-beam headlamps and for daytime running lamps.
Since 2017, ams OSRAM has increased the luminous efficacy of the OSLON Compact PL product family by 33% (24.6lm/W). The increasing efficacy enables car makers to reduce the climate impact of operating vehicle lighting systems. The higher brightness of the new OSLON Compact PL also gives lighting equipment designers a wider set of options for the choice of components in the optical assembly, such as light guides.
“Higher optical power output from the same footprint means that automotive OEMs can now do more with less,” notes product marketing manager Florian Fink.
Multiple variants give design flexibility
The new AEC-Q102-qualified OSLON Compact PL is based on ams OSRAM’s UX.3 chip. It is certified for corrosion robustness to Class 3A.
The single-chip variant produces a typical luminous output of 440lm, compared with the second generation’s 405lm. The OSLON Compact PL is also available in 2-, 3- and 4-chip variants, and with a light-emitting surface area of up to (1150μm)2.
Two package options are available. The three-pad version includes one isolated thermal pad for increased heat dissipation. The two-pad version has larger pads to provide a more stable bond with a low-cost aluminium PCB.
The six products in the third-generation OSLON Compact PL series are:
- KW CWLPM3.TK – single 1150μm chip, two-pad LED, typical 455lm output;
- KW CELNM3.TK – single 1030μm chip, three-pad LED, typical 440lm output;
- KW CWLNM3.TK – single 1030μm chip, two-pad LED, typical 440lm output;
- KW2 CFLNM3.TK – dual 1030μm chip, four-pad LED, typical 880lm output;
- KW3 CGLNM3.TK – triple 1030μm chip, four-pad LED, typical 1320lm output;
- KW4 CHLNM3.TK – quad 1030μm chip, four-pad LED, typical 1760lm output.
The OSLON Compact PL is available to order now for volume production.
