|An Overview - Advanced Packaging for Solid State Light Emitting Diode (SSLED) Lighting|
|Keywords: Solid State LED Lighting, thermal management, low cost|
|Implementation of advanced packaging concepts in SSLED lighting has the potential to make a huge positive impact on worldwide energy and environmental concerns. In US Department of energy studies (ref 1), it has been estimated that, on the average, 2.1 quads of energy (the equivalent to 55 million tons of oil) could be saved annually by the nationwide implementation of SSLEDs for general illumination. This paper will present an overview of the issues for current SSLED lighting technologies, and how advanced packaging and integration concepts can address these concerns. In traditional lighting sources, the majority of the heat generated is dissipated by radiation. However, in SSLEDs the heat has to be conducted away from the source. Without adequate thermal management to minimize the junction temperature of the solid-state device, both performance and lifetime will be adversely affected. Cost is another major factor preventing the widespread use of SSLED lighting. Currently LED lights cost 50 to 100 times more than traditional lights. Despite the considerably longer lifetime of an LED light, the average consumer is not willing to pay the higher upfront cost. The key to addressing these concerns is having a packaging solution that will provide adequate thermal management at a lower price. Some of the packaging solutions used by the industry, and some advanced concepts that could be used will be presented. *Sandia is a multi-program laboratory operated by Sandia Corporation, a Lockheed Martin Company for the United States Department of Energy under contract DE-AC04-94AL85000.
