OSRAM on electronica 2006

Orientation sensor SFH 7710 - The only way is up!
 
There is no need to rotate digital pictures to view them thanks to the tiny SFH 7710 SMT orientation sensor from OSRAM Opto Semiconductors. It reliably detects whether a photo has been taken in portrait or landscape format and forwards this information to appropriate software, which then automatically displays the photo in its correct orientation.

The SFH 7710, which measures 4.4 x 4.4 mm and is just 1.8 mm high, is the first optical orientation sensor of this size in SMT technology. It is housed in a plastic package and is suitable for standard solder processes. More cost-effective than existing MEMS sensors (MEMS = Micro-Electro-Mechanical System) and with very low power consumption it is ideal for widespread use in mobile terminals such as mobile phones, PDAs and digital cameras.

The orientation sensor has an integrated light barrier comprising an IR emitter and a detector. In the detection field of the light barrier there will be a movable object, in either portrait or landscape format depending on the orientation of the mobile terminal. If the terminal is then rotated the object will move out of the detection field of the light barrier. The sensor sends the information as to whether the object is within or outside the detection area as a unique signal via a digital output. Appropriate software then processes the signal and rotates the contents of the display if necessary. A photo for example will immediately appear in the correct position for viewing. There is no need to bother about realigning it after downloading. The sensor operates on a supply voltage of 2.5 V and has a current draw of less than 50 µA on average.
 
OSTAR Headlamp - with or without optics: When LEDs conquer headlights...
 
...there will be no limits to a designer's ingenuity. These compact light sources will give designers untold freedom. With OSTAR Headlamp and, at a later date, with OSTAR Headlamp Hot Spot, OSRAM Opto Semiconductors is targeting headlights that work with reflection systems and those with projection systems. Both LEDs will be qualified according to automotive standard AEC-Q101 and easily achieve the brightness level of halogen lamps.

Each of the two high-power light sources is equipped with five tightly packed ThinGaN chips which together produce light with an extremely high brightness level. For a typical forward current of 700 mA the OSTAR Headlamp achieves 250 lm, and the OSTAR Headlamp Hot Spot as much as 350 lm. Four of these LEDs are therefore sufficient to generate as much light as a halogen lamp. A larger number would be needed to produce the same level as a xenon lamp.
 
Without optics the LEDs meet the requirements of reflection systems. The light from these surface emitters can be injected perfectly in customer-specific optics. In the Hot Spot version a special lens is used as the primary optics to focus the light. 
The two models have a high colour temperature of 5600 K that is closer to natural daylight than other headlight sources. In particular this improves visibility at the edges of the illuminated zone because the human eye is better at perceiving objects in daylight white light than in other light colours. The LEDs provide concentrated light from a small surface area and are therefore ideal for use in headlights.
 
Customer-specific lenses enable a wide range of designs to be produced. OSRAM can provide application support on request. Robust, vibration-proof and moisture-resistant, these light sources generate white light in the ECE and SAE standard range. They can easily withstand the extreme temperatures in headlight applications (-40 to +125°C operation temperature).
 
The LED Light for you network is growing fast
 
Only six months after it was launched by OSRAM, the LED Light for you (LLFY) network now has about 25 certified partners from all around the world. The network offers lighting designers and architects high-quality advice and support for current and future projects in the three core areas of optical, thermal and electronic solutions.
 
Thanks to rapid increases in luminous efficacy and their familiar benefits such as long life and small dimensions, LEDs are now being used more and more for general illumination. The range of applications includes everything from backlighting to traditional luminaires. Many users however lack experience of using these relatively young light sources. OSRAM has therefore brought together the combined expertise of certified partners on the LLFY internet platform, providing a starting point and tips on using LEDs for general illumination. The platform also gives the latest information on all the components needed to create lighting solutions with LEDs.

Since the platform was launched in April 2006 OSRAM has already certified 25 partners worldwide. The main criteria for certification are core competence and a commitment to LEDs for general illumination. "The customer must be able to rely on the quality of the services offered", said Volker Härle, Director of LED Marketing. LLFY already offers a balanced portfolio of companies, from highly specialised comparatively small regional firms to international enterprises in the focus regions of Europe, Asia and the countries in the North American Free Trade Agreement (NAFTA).
 
Partner events and workshops on optical, thermal and electronic solutions give employees in the participating companies the opportunity to make personal contacts and thereby benefit from an exchange of know-how. Joint advertising campaigns will follow. www.ledlightforyou.com

Ordering LEDs is as easy as clicking a mouse
 
OSRAM Opto Semiconductors' new Internet Light Shop offers LEDs of all shapes and sizes. The shop will be open in time for the Electronica fair. At www.osram-os.com/lightshop even small quantities of any of the wide range of products can be purchased. The Light Shop is intended for potential customers such as developers, architects, lighting planners, universities and private individuals who only want small quantities of these semiconductor products.

Simply click on the "Buy Here" button for the product you want and you will be taken to the website of our sales partner. This is RS Components for Europe and Asia, and Digi-Key in the NAFTA region. These two distributors have geared themselves up to handle small quantities of the OSRAM products.
 
Visitors to the fair can obtain information on the new Light Shop either at the OSRAM stand (A4.107) or at the stands of our sales partners (RS Components A6.257, Digi-Key A5.276).
 
Virtually the entire range of products from the specialist semiconductor producer will be available: LED families, infrared components, high-power laser products for the end consumer market, OLED displays and a wide range of LED displays for indoor and outdoor applications.

OSRAM's bright presence
 
OSRAM Opto Semiconductors is lighting its 160 m² stand at this year's Electronica fair entirely with high-power LEDs. The semiconductor lighting company is using this lighting concept to demonstrate the enormous advances in the brightness of light emitting diodes and their suitability for general lighting applications.

The stand has four distinct areas - Business, Living, Lounge and Wellness. The Business area is lit by daylight white LED light sources to help visitors concentrate and pay attention, whereas the other areas have warm white LEDs to create a pleasant relaxing atmosphere. The 120 LED spotlights, each equipped with six OSTAR Lighting LEDs, are capable of delivering up to 1760 lumen each, depending on the white tone. This exceptional brightness is primarily thanks to new technologies such as ThinGaN and Chip Level Coating, without which modern high-power products such as OSTAR Lighting would not be possible.
 
In the Wellness area white high-power Golden DRAGON LEDs are used in conjunction with a wide-angle ARGUS lens to backlight the floor coverings of matt glass and white artificial grass. The principle is known from scalable displays. A small viewing window is provided so visitors can see the backlighting system. Impressive lighting effects on the steps and acrylic banisters round off the overall lighting concept. When people approach the steps a light barrier comprising IR sensors activates an exciting lighting scene.
 
With their high output, LEDs are being used for more and more applications in general room lighting. Advantages such as long life and small dimensions - combined with greater freedom of design - will ensure a permanent place for semiconductor light sources in this sector.
