IR Dragon Family for Automotive, Industrial and Consumer applications

IR power in a small package

You can only get this much power from IR DRAGON, OSRAM Opto Semiconductors' strongest infrared emitter. Besides stellar performance in a small package, the IR DRAGON offers a long service life and high power in continuous driving mode thanks to its excellent thermal design. It operates at wavelengths designed to support CMOS and CCD camera applications.

The IR DRAGON benefits are unique in the infrared galaxy

Intergalactic performance

Thinfilm technology allows the IR DRAGON to achieve a wall-plug efficiency of approx. 35%. This corresponds to approximately half the value that can be achieved using semiconductor lasers and is superior to using spontaneous emitters.

A star in reliability

The IR DRAGON also has an extraordinarily long lifetime in DC mode, showing extremely stable behaviour. Furthermore, the package demonstrates a very good thermal design.

A galaxy of applications

The wavelength is designed for all CMOS/CCD camera applications. The IR DRAGON is also qualified for automotive applications.

SMT package:

  • The package comes with two wavelengths: 850 nm and 940 nm (strongly reduced red glow)
  • It’s also available with our new Nanostack technology which means nearly twice the optical output of our standard version
  • The IR DRAGON demonstrates high efficiency in a very small package with an emission area of 1 x 1 mm
  • The package is characterized by low thermal resistance and allows a maximum DC current of 1 A
  • Naturally, IR DRAGON is RoHS compliant and qualified for automotive applications

The IR DRAGON is suited for all infrared illumination projects. With this product, you can leap into a new galaxy of applications. The following examples are based on infrared illumination:


  • Pre-crash sensor
  • Seat occupancy
  • Driver assistance systems


  • Surveillance system (CCTV)
  • Machine security systems


  • Night vision flashlights for camera

Max. forward current (DC mode): 1 A
Thermal resistance: 9 K/W
Active chip area: 1 mm²
