Kudos to the author for writing about a necessary and important subject. Given the fact that LEDs are about to take over in hundreds of new applications in the next ten years, ranging from automobiles to aircraft to medical equipment, a primer on this subject is badly needed.
The information presented is certainly very useful, and presented in an interesting and usable manner. But the information about heat removal is missing, it appears. Since heat is the primary challenge in LED lighting, it is important, even vital, that anyone designing LED lighting understand both the heat generation and the heat removal mechanisms. After all, the selling point of the more expensive solid state lighting systems is reliability and long life, the two things that heat limits most.
I'm visiting a customer on the East coast this week. While driving, I've noticed that the city opted for LED traffic signals. They come to one's attention because about 30% of the LEDs in the lights are non-functional (the green lights are quite noticable). Is there really a longevity gain by switching to LEDs?
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
