SSL system Reliability: Graphical approach
Failure of a complex SSL system always consists of multiple root causes at component level, and multiple interactions of these multiple failure modes. Hence, we provide a graphical statistical based framework to approach SSL system reliability prediction.

The multi-scaled failure mechanism of SSL system
Because the diversity and complexity of the LED lighting product design, it results in system failure modes which can occur in various value chains, and interact with each other.

Testing method for SSL products
The SSL reliability is a multi-function, multi-disciplinary, multi-scaled, multi-technologies, multi-materials and multi-interfaces. Nowadays the “Trial-and-error” is mostly applied. It causes the long “time-to-market” without the guarantee of “first time right”. Due to lacking of the fundamental research upon the SSL reliability and modeling methods, it causes of about 3B (usd) annual losses.
