Osram Opto Semiconductors has increased the output of its IR Oslon Black LED family by more than 70 percent compared to the standard version. This was achieved by combining the latest chip design with an optimized package and Nanostack technology, in which each chip has two emission centers arranged one above the other.
Depending on the type of external optics and the application, the new infrared light emitting diodes (IREDs) – the SFH 4715AS and SFH 4716AS – can provide illumination over a distance of more than 100 meters (109.36 yards), which makes them even better light sources for many camera-based applications, said Osram.
Thanks to their high optical output of 1.37 watts (W) at 1 ampere (A), the IR Oslon Black Stack components are the most powerful IREDs from Osram Opto Semiconductors, said the company. Targeting surveillance camera applications, the IREDs also are well suited for a variety of other industrial camera-based applications such as 3D process control cameras to determine the distance from an object by measuring the propagation time.
Technical data for SFH 4715AS/SFH 4716AS:
|Package size||3.85 mm x 3.85 mm x 2.29 mm/ 3.85 mm x 3.85 mm x 1.51 mm|
|Optical output at 1 A||1.37 W|
|Centroid wavelength||850 nm|
|Efficiency||typically 43 %|
|Thermal resistance||max. 9 K/W|
|Beam angle||90° / 150°|
The package dimensions of the Oslon Black Stack components remain the same at 3.85 mm x 3.85 mm x 2.29 mm or 1.51 mm. They also still offer a choice between beam angles of 90 and 150 degrees, providing for drop-in replacement.
