July 24, 2008[Engineering Essentials] Designing Multichannel HBLED Systems
High-brightness LEDs (HBLEDs) are increasingly becoming the light source of choice in both general and specialty lighting applications. Advances in LED technology have led to higher lumens per watt. Improvements are also being made in package size, color options, color rendering index (CRI) ratings, binning, and temperature stability. LEDs bring flexibility, efficiency, and intelligence to any lighting application. A typical application of such...

July 24, 2008[Engineering Essentials] Beyond The $10 Million Light Bulb
Signed into law in January, the Energy Independence and Security Act of 2007 directs the U.S. Department of Energy (DOE) to establish the “Bright Tomorrow Lighting Prizes” (L Prize) competition. This contest is designed to spur the development of ultra-efficient, solid-state lighting products to replace the common light bulb. Specifically, the DOE hopes to replace the 60-W incandescent lamp and the PAR 38 halogen lamp. It also calls for a...

July 24, 2008[Ideas For Design] Use A Boost Converter To Create An Auto-Dimmable LED Flashlight
Due to their light output and long life, high-brightness LEDs are well-suited for use in flashlights. Typically, the LEDs are driven with a constant current. So when the battery voltage drops, the flashlight just stops working. In some situations, this could be dangerous. It would be nice to have a flashlight that would automatically dim when the battery voltage drops. Just like a traditional flashlight, it would indicate a low-battery condition and...

July 24, 2008[Engineering Essentials] Secret Sauce And Sandpaper
Continually improving white LEDs depends to a great extent on proprietary improvements in the chemistry and art of phosphor deposition. Cree considers that part of its intellectual property very secret. However, McClear was willing to talk about a recent breakthrough in backend processing, one that he figures the competition will catch onto fairly quickly. In fact, the development has to do with the LED diodes themselves. In normal practice, when the diodes on a wafer are...

July 24, 2008[EEPN In Electronic Design] Early Warning Is In The Air For Effective Thermal Management
For today’s makers of high-reliability equipment, increased performance requirements have meant packing more and more hardware onto boards and stuffing higher-density boards into shrinking chassis. As a result, the power density (power dissipated per unit area) of electronic products, measured by the ability to dissipate heat, has skyrocketed, increasing by a factor of 20 to 50 in the last few decades. More and more, hot new products mean hotter chips and...

[Technology In The News] iPhone Adds 3G Functionality, Drops Cost
iSuppli – After a teardown of the iPhone 3G, iSuppli Corp. confirmed a significant drop in bill of material (BOM) costs, indicating a cheaper end product than last year’s 2G iPhone. At $174.33, the BOM and manufacturing cost of the new iPhone is markedly less than the $227 that iSuppli estimated for the first-generation, 8 Gbyte 2G version in June 2007. This strip down results in about $100 less for consumers, totaling $499 for the iPhone 3G, whereas last year’s model called for $599.

July 10, 2008[Technology Report] MEMS The Word... In Consumer Electronics
Demand for devices that can sense motion, orientation, and location is surging, and it runs the gamut from the hottest video games to critical medical technology. With accelerometers and gyroscopes based on microelectromechanical systems (MEMS) rapidly maturing, that demand is being met. Many of the latest consumer products include one or more MEMS IC functions that measure and control factors like movement, position, force, and even temperature. As a...

[Design View / Design Solution] Smart Optics Push Camera Phones Out Of The “Dark” Ages
Since the introduction of the camera phone in 2001, having a camera in a cell phone has transitioned from being an added feature to a standard item. Today, more than 80% of cell phones have at least one camera. Camera-enabled phones offer the convenience of having a camera that’s permanently on and, quite literally, “on-hand” for every occasion.

[TechScope] "Friend" Your Picture Frame
We’re barely keeping up with the social networking technology that Web 2.0 applications require. Yet already, designers and marketers alike are buzzing about Web 3.0, even though nobody seems to be able to specifically define what that means. Nonetheless, most experts predict high-speed, wide-bandwidth applications that will be able to deliver content wherever and whenever you want it, regardless of format or platform. Web 3.0 will even come to devices as mundane as, say, picture frames.
