Alternative calculation method will improve thermal analysis of LEDs
May 17, 2013
Up until now, thermal analysis of white LEDs has been an imperfect science. Too often LED lamp and luminaire manufacturers rely on insufficient, inaccurate or intangible data to determine the thermal performance of the LEDs in their applications, and, as a result, may over-engineer their heat sink design. ...

Dangers of Aftermarket Counterfeit Battery Packs
Wed, 22 May 2013 13:28:00 +0200
The continuing growth of portable handheld devices has spawned a healthy selection of aftermarket battery pack suppliers. Both the OEM and end user pay a price when counterfeit battery replacements are chosen. The quantifiable impact of imitation battery packs to the OEM includes increased safety risks for their ustomers, greater product returns due to non-performing batteries, reduced customer satisfaction, and reduced revenue for batteries supplied by the original manufacturer. This paper details some of the safety issues observed in counterfeit battery packs and presents options to implement a prevention program to control the aftermarket ecosystem.
