I recently purchased a Fenix PD35 850 lumen LED flashlight and it comes with a warning label that it becomes hot to the touch after running on full for a period of time. After that time period comes, the micro-circuitry powers it down to the next highest setting (and so on) in order to prevent damage. Good article on the subject.
Great discussion on the finer points of LED design considerations. Also, in addition to price drop, in many cases LED's can also offer the advantage of longer life over the other technologies that they are replacing.
I agree. This Mentor Graphics LED Thermal/Performance analysis software package would have been great to use when I was developing LED lighting fixtures while working at Hunter Fan. This data would have served as a baseline while taking actual thermal and lumen measurements using an Integrating Sphere. Management of thermal and lumen performance of LEDs is quite a challenge especially when you have to add the SMPS (switching mode power supply) LED drivers heat dissipation data using a per-square inch pcb in to the overall thermal equation. Nice article!
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
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.
