Osram adds to Oslon Black infrared LED family for automotive applications, boosting pulsed current to 5A for improved road safety

Osram Opto Semiconductors GmbH of Regensburg, Germany is expanding its Oslon Black family with six new infrared LEDs (IREDs) for automotive use.

The 850nm versions are intended for exterior applications, enhancing advanced driver assistance systems (ADAS) such as night vision, pedestrian protection and lane detection technologies. The new 940nm versions are better suited for interior applications like driver monitoring, interior cabin monitoring and gesture recognition. Due to a dynamic range of wavelengths and lenses, these products cover a wide array of customer requirements and can be operated at up to 5A in pulsed mode (compared with 3A previously).

The IREDs are intense, with an optical output of up to 2W in continuous operation, and deliver various wavelengths and beam angles.

The SFH 4715AS A01, SFH 4716AS A01 and SFH 4717AS A01 all have a wavelength of 850nm and beam angles of ±45°, ±75° and ±25°.

The SFH 4725AS A01, SFH 4726 A01 and SFH 4727AS A01 all have a wavelength of 940nm and beam angles of ±45°, ±75° and ±25°.

A high-refractive-index silicone is used for each lens, giving the IREDs a particularly low profile so that only very little light is lost from the sides. The maximum operating temperature of the IREDs is 125°C.

The high optical pulse outputs and wide range of integrated lens options allow system designers to select the right IRED for virtually any application without installing secondary optics, says Osram. Infrared light sources with a wavelength range <900nm are perceived by the human eye as a red glow. This is largely suppressed at 940nm. Like the rest of the Oslon Black family, the new IREDs offer what is claimed to be outstanding performance, long lifetime and excellent thermal properties.

“With this product line within the Oslon Black family we can cover all IRED-based lighting applications inside and outside the car,” says Walter Rothmund, marketing manager ELS at Osram Opto. “The exemplary performance and compact dimensions of the IREDs give engineers maximum freedom of design, and end customers benefit from a new level of road safety,” he adds.
