Infrared LEDs deliver high pulse handling up to 5A for ADAS

Osram Opto Semiconductors has expanded its Oslon Black family for the infrared range with six new automotive IREDs.

The 850 nm versions are intended for exterior applications such as night vision, pedestrian protection, pre-field recognition and lane detection. The new 940 nm versions are suitable above all for interior automotive applications such as driver monitoring, seat occupancy detection and gesture recognition. Thanks to different wavelengths and lenses these products cover a wide range of customer requirements and can be operated at maximum pulse current of up to 5A, compared to 3A previously. The IREDs are particularly bright, with an optical output of up to 2.0 W in continuous operation. The six new IRED versions are available in different wavelengths and beam angles. SFH 4715AS A01, SFH 4716AS A01 and SFH 4717AS A01 all have a wavelength of 850 nm and a beam angle of ±45°, ±75° and ±25° respectively. SFH 4725AS A01, SFH 4726 A01 and SFH 4727AS A01 all have a wavelength of 940 nm and a beam angle of ±45°, ±75° and ±25° respectively. A high refractive index silicone is used for the lens, giving it 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.
