High power version of the OSRAM Ostar LED is the highlight of the projector source for the system output up to 1700 lumens projector Projection

December 17, 2013 - China News - OSRAM Opto Semiconductors for brightness up to 1700 LM projector applications launched OSRAM Ostar Projection high power version of the two. Thanks to the optimized product design, these two versions are able to produce high luminous flux from the effective chip surface. Their luminous flux ranges from 1000 LM to 8300 LM, depending on the color and LED version. These two new LED was coated with anti reflective coating glass instead of ordinary lens, combined with external optical elements, effectively ensure the emitted light is able to bundle together. Therefore, they are very suitable for the use of a variety of additional optical components to achieve efficient lighting.

These two new light-emitting diodes produce high luminous flux, enough to be used in the brightness level of up to 1700 LM in the office projector. Product center is a high current LED chip mm - 2, it's top film technology and UX:3 technology based on the manufacturing and. The two version of LED contains two chips (P1W) and four chips (P2W), the total luminous area were 4 mm and 8 mm - L.

LED projector uses red, green, blue three LED as light source. Three LED pulse drive (color sequence mode), so the projector does not need to use the traditional light bulb projector color filter. These two new LED using technology to achieve high output Green Chip Technology and the latest OSRAM C - conversion, so the high light output. The brightness of the light emitted by the P2W version is 1000 LM (blue), 2500 LM (red) and 8300 LM (green). These high brightness levels require up to 32 A (per chip of 8 A) current pulses, and the need to optimize the product design and effectively dissipate the heat generated.

In order to support such a high current, P2's four high power chips are connected in parallel, said Stefan Morgott, head of the projector application division at OSRAM's headquarters in semiconductor, germany. Only in this way, the new OSRAM Ostar LED in order to generate the maximum brightness from the chip, the real light source of a large imager Projection. In fact, this opens up new applications for LED projectors in offices and classrooms. "

High degree of new LED

OSRAM Ostar Projection allows the light to be transmitted as efficiently as possible through the optical system, while the optical system is limited by the amount of optical expansion. It retains the optical expansion of the light-emitting diode two, and then with the external optical components, can produce a very narrow beam. The amount of optical expansion describes the relationship between the light emitting surface and the projection surface.

In order to keep the thermal resistance and rising temperature of LED at a very low level, the chip is mounted directly on the copper plate, rather than the traditional LED package. The utility model is fixed on the copper plate by screws, and is helpful to improve the connection between the heat sink and the radiating fin.

These two new OSRAM Projection LED will be held on January 7, 2014 to 10, the international consumer electronics show, the first appearance of the technology, mass production is scheduled to start in March, in.
