Infrared Lighting LED supplies 3.5 W of optical output power.

Press Release Summary:

With 6 thin-film chips and hemispherical lens, Infrared OSTAR LEDs are available in 2 wavelengths. At 850 nm, SFH4750 is optimized union of maximum spectral sensitivity for CCD and CMOS cameras with suppressed visibility for human eye. SFH4751 has 940 nm wavelength to which human eye is almost insensitive, making it suited for applications where visibility of light source must be eliminated. Beam angle and radiant intensity of both models can be varied with standard secondary optics.

Infrared OSTAR Lighting LEDs Provide Compact, Powerful and Efficient Radiance

Sunnyvale, CA, April 16, 2009

Open design allows for precision adjustment with external optics

With six powerful thin-film chips and a hemispherical lens, the new Infrared OSTAR Lighting LED from OSRAM Opto Semiconductors produces 3.5 W of optical output power at an operating current of 1 A. The beam angle and radiant intensity can be varied with standard secondary optics which are readily available on the market. The hexagonal honeycomb shape of this high-power component enables multiple IR LEDs to be combined to form a large space-saving matrix so that the output power can be increased many times. Major applications for the IR OSTAR Lighting LED include industrial lighting for camera-based surveillance systems such as CCTV and intelligent transportation systems (ITS).

The IR OSTAR Lighting LED is available in two wavelengths. At 850 nm, the SFH4750 is an optimized union of maximum spectral sensitivity for CCD and CMOS cameras with suppressed visibility for the human eye. The SFH4751 is a version with a wavelength of 940 nm, to which the human eye is almost insensitive. This model is used in applications where visibility of the light source must be eliminated. "We were able to bring the infrared OSTAR Lighting quickly to market because of the synergies among the various technologies at the product development stage," said Harry Feltges, Marketing Manager for Infrared Components at OSRAM Opto Semiconductors. "The package is the same as our popular white OSTAR Lighting, so our customers can take advantage of the shared thermal and mechanical designs."

With their high optical output, both versions of the IR OSTAR Lighting LED are good choices for industrial lighting illumination units for CCTV systems. These systems are used to improve public safety on the streets, at railway stations, at airports and in schools, and also to protect museum exhibits against theft. 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).
