Osram Opto Semiconductors has introduced two new high-power versions of the Osram Ostar Projection for projectors with a brightness of up to 1700 lumen. The Osram Ostar Projection LEDs offer high luminous flux from the available chip surface. Between 1000 and 8300 lumen can be produced depending on the color and the LED version. An antireflex coated glass cover instead of the usual lens, together with external optics, ensures that the light is well bundled, the vendor said. The two new LEDs can be used in office projectors with brightness levels of up to 1700 lumen. At the heart of the product is a 2-square millimeter LED high-current chip based on thin-film and UX:3 technologies. The two LED versions contain two (P1W) or four chips (P2W) with a total luminous area of 4- and 8-square millimeter, respectively. The two new Osram Ostar Projection LEDs will be premiered at the 2014 International CES. Volume production is due to start in March, Osram said.

Osram's Dragon Dome provides a focused beam of high-power Infrared LED (IRED) with a range of more than 100 meters. It has a compact design and does not need an external lens. With its wavelength of 850nm, this LED can be used as a light source for security surveillance tasks such as CCTV, the vendor said. The Dragon Dome SFH 4783 emits its light within a narrow (��12 degrees) beam angle. From a current of 1A, it achieves a total radiated power of 430 milliwatts (mW), and therefore a radiant intensity of 2.3 watts per steradian (W/sr). At this radiant intensity, the beam of light will have a usable range of more than 100 meters, depending on the sensitivity and field of view of the camera. Radiant intensity is measured in W/sr and indicates the light output within a solid angle segment. The high total radiated power of this IRED is made possible by the thin-film technology, which enables the light to be extracted efficiently from the chip, Osram said.
