Osram boosts output of Oslon Black IR LEDs again for longer-reach surveillance cameras

Osram Opto Semiconductors GmbH of Regensburg, Germany says that it has increased the output of its IR Oslon Black family for the second time in six months, making the new SFH 4715AS and SFH 4716AS the most powerful infrared light-emitting diodes (IREDs) yet from the firm.

Compared with the standard version, the increase in optical output of over 70% (to 1.37W at a current of 1A), has been achieved by combining the latest generation of chips, an optimized package design and, most importantly, Nanostack technology, in which each chip has two emission centers. Depending on the type of external optics and the particular application, the IREDs can provide illumination over a distance of more than 100m, making them better light sources for many camera-based applications.

"The new Oslon Black Stack generates more light and can therefore provide even better illumination over large distances than the previous versions," says Dr Jörg Heerlein, marketing infrared at Osram Opto. The power IREDs are the preferred light sources for surveillance cameras, adds the firm. Depending on the type of camera and the number of integrated IREDs, distances of more than 100m can be illuminated with infrared light.

In addition to their main application in surveillance cameras, the IREDs are also suitable for many other industrial camera based applications, notes Osram Opto, for example, in 3D process control cameras to determine the distance from an object by measuring the propagation time.

The Oslon Black Stack's package dimensions remain unchanged at 3.85mm x 3.85mm x 2.29mm or 3.85mm x 3.85mm x 1.51mm. There is also still a choice between beam angles of 90° and 150°, so replacement is straightforward.
