Ostar LED produces 3.5W optical output power

With six powerful thin-film chips and a hemispherical lens, the infrared Ostar lighting LED from Osram Opto Semiconductors produces 3.5W of optical output power at an operating current of 1A.

The beam angle and radiant intensity can be varied with standard secondary optics, which are readily available on the market.

The hexagonal shape of this component enables multiple IR LEDs to be combined to form a large space-saving matrix so that the output power can be increased.

The IR Ostar lighting LED is available in two wavelengths.

At 850nm, the SFH4750 is an optimised union of maximum spectral sensitivity for CCD and CMOS cameras with suppressed visibility for the human eye.

The SFH4751 version has a wavelength of 940nm, to which the human eye is almost insensitive.

This model is used in applications where visibility of the light source must be eliminated.

With their high optical output, both versions of the IR Ostar lighting LED are suitable for industrial lighting illumination units for CCTV systems.

These IR LEDs have a very long lifetime, even in pulsed-mode applications.

They are, therefore, suitable as light sources for intelligent transportation systems such as traffic monitoring, toll systems and automatic number plate recognition (ANTR).
