A “life cycle thinking” approach to assess differences in the energy use of SiC vs. Si power semiconductors

Wide bandgap (WBG) semiconductors have the potential to provide significant improvements in energy efficiency over conventional Silicon (Si) semiconductors. While the potential for energy efficiency gains is widely researched, the relation to the energy use during manufacturing processes remains insufficiently studied. This question is especially relevant for Silicon carbide (SiC) semiconductors, as there are some […]

Literature Summary of Lifetime Testing of Light Emitting Diodes and LED Products

A summary of the literature on lifetime definitions for LEDs and LED products, including a look at failure mechanisms, accelerated life tests and test methods for estimating lifetime, and provides some recommendations. There is currently no agreement as to which test method can best estimate the lifetime of LED lighting products and the report thus addresses a key issue for regulators and industry interested in deployment of LED technologies
