Packaging compact OSRAM latest chip stacking technology help infrared

OSRAM Opto Semiconductors launched infrared Platinum Dragon, light emitting area is small, but very high brightness. The LED thin film chip area is only 1 mm2, using the chip lamination technology, just a driving current of A, the output power can reach about 1 W, which is almost the current standard chip of two times. Equipped with different standards of the two optical element, the LED can produce different visual angle and radiation intensity, especially suitable for applications requiring high brightness, small volume light source, such as a pedestrian protection system and vehicle night vision system.

The new Platinum Dragon can have such a good brightness, mainly due to the special thin film chip. It is not only a P-N junction, but there are two interfaces, one of the links or "stacked" at the top of the other, so that the output power of light to achieve nearly two times the traditional infrared thin film chip. OSRAM Opto Semiconductors Germany headquarters infrared components Marketing Manager for Harry FELtges said: "we can launch the infrared Stack Dragon so quickly, thanks to our experience in the development of laser technology in the stack. In addition, the new LED uses infrared package form is the same as other infrared Dragon components, so it can be used not only in design, without requiring any changes to the "1 A operating current positive voltage is 2.9 V, so it can be used for the voltage range of standard LED driver. The infrared LED emission wavelength of 850 nm, just in the CCD and CMOS camera maximum spectral sensitivity and the visibility of the visually impaired.

Small area, high brightness infrared Platinum Dragon, is the ideal lighting solution for small space applications. Because only a few infrared LED can provide the same optical output power, so the vehicle night vision system, pedestrian protection system and pre crash sensor can also become more compact. In industrial applications, the high power infrared LED can be used for closed-circuit television (CCTV) camera lighting components, can also be built into the license plate automatic recognition system (ANPR). Three dimensional camera technology is another feasible application, will gradually be widely used in the game platform and television and other consumer devices, in order to achieve gesture recognition. This type of application requires a high frequency (20 to 50 MHz), and the new infrared Dragon can easily achieve this requirement.

Stack Dragon infrared small area, high brightness, achieve the performance of the optical output unprecedented, open up new possibilities for future applications. Source: OSRAM
