The new micro projector of 3M, a diversified technology company, uses LEDs from OSRAM Opto Semiconductors. The camera can be connected to mobile phones and digital cameras, opening up a new era of mobile projection. The compact, bright, and energy-saving diode is the key to developing a micro projector, which can achieve performance that other light sources cannot achieve, and the screen projection size has successfully exceeded the 1 meter mark.
3M's new pico projector, the MPro120 PocketProjector, is the size of a mobile phone and can project photos or videos onto a wall for easy viewing. This major breakthrough is due to the OSTAR SMT LED light source specially designed by OSRAM Opto Semiconductors for the individual requirements of 3M. These LEDs can project images of more than one meter depending on lighting conditions. The MPro120 can also be connected to other devices with AV input such as digital cameras and laptops.
“Small, economical and color-developing.†Wolfgang Schnabel, marketing manager of OSRAM Opto Semiconductors Germany, said: “The perfect combination of thin-film chip technology and specially developed LED housing makes it possible to emit the brightest light with minimal space. LEDs have low power consumption, which saves projector battery power and extends projector life. This is critical for mobile projection applications."
The projector is made with a 3M light engine and LEDs from OSRAM Opto Semiconductors with an energy efficiency of up to 10 lumens per watt. It is equipped with a multi-chip LED consisting of two green chips, a red chip and a blue chip. The color rendering is excellent and even meets higher standards.
Kay-Uwe Schenke, market development manager for 3M Germany, commented: “Last year, 3M was the first to introduce a miniature projector with LED technology. The new MPro120 PocketProjector is now coming to the forefront of user needs and requirements. The pocket projector developed on the screen. In addition to its full VGA resolution, its distinctive features include market-leading brightness, integrated speakers and a projection size of 20-127 cm (depending on lighting conditions). Just use a laptop or multimedia phone to easily project anywhere, anytime."
For different types of projection applications, OSRAM Opto Semiconductors has launched a full range of LED products. For example, OSTAR Compact is tailored for small devices such as cell phones, PDAs, and music players, while OSTAR Power Projection is tailored for high-performance projection applications such as home theater. This means that OSRAM Opto Semiconductors' LED product portfolio can meet all projection system requirements from 1 watt to 300 watts.
The 3M new MPro120 PocketProjector made with ultra-efficient OSTAR LEDs has made instant projection never been easier.
OSTAR SMT is the best choice for pico projectors and the underlying technology for the MPro120 light source.
