Osram Ostar Projection Cube LED: A Giant Leap for Smartphones and Cameras

Double the system brightness for embedded projection thanks to a new green LED component from Osram Opto Semiconductors. An integrated miniature projector that can display images on a much larger surface than existing displays is the next giant leap for smartphones and cameras. This is known as embedded projection and uses LEDs as the light source. The greatest challenge so far for lighting technology has been the limited efficiency of the green light emitting diodes. This is because high brightness is essential if the projected image will be seen with ambient light. The Osram Ostar Projection Cube from Osram Opto Semiconductors is the perfect answer.

Efficient LEDs for red and blue light have been available for some time but LEDs that produce green with acceptable output have been rare. The new Osram Ostar Projection Cube from Osram Opto Semiconductors has now plugged this important gap. At 110 lumen per watt (lm/W) it is much more efficient than all other previously available green LEDs in the embedded projection sector.

For the first time, the Osram Ostar Projection Cube enables high output to be achieved in embedded projectors. "The new LED almost doubles the brightness in smartphone applications so embedded projectors with a system brightness of up to 25 lumen are possible", said Wolfgang Schnabel, Marketing Manager Projection at Osram Opto Semiconductors. This means that the image is clearly visible even with ambient light and, thanks to the efficiency of LED technology, the projector can also be used in mobile applications with limited battery capacity.

Lots of light in a small space
The new green LED is available in two versions – with a 1 mm edge length chip and with a 0.75 mm edge length. The Osram Ostar Projection Cube is therefore suitable for all standard imager formats in mobile terminals. The two LED versions are also very bright. Depending on the size of the chip, they produce 260 lm at 700 mA and 2.3 W or 130 lm at 350 mA and
1.2 W.

This high luminance from a small surface area is made possible with the aid of special encapsulation. This sharply defines the light surface so the light is emitted from this defined surface without package reflections. With an area of 3.8 x 4.1 mm² and a height of only 0.6 mm the new LED enables extremely low-profile projection units to be designed – ideal for modern smartphone and camera designs. Osram Ostar Projection Cube does not have a glass cover, which means that external optics can be placed very close to it and the light can be used efficiently.

Francis Nguyen from Osram Opto Semiconductors will present this new LED at the Projection Summit 2012 in Las Vegas during his talk on the "Evolution of LEDs used in Picoprojectors" (June 11, 2012).

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon.

The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.
