U.S. Department of Energy (DOE) Lighting Program Manager Dr. James
Brodrick sent out a recent fact sheet from his office on Solid-State Lighting (SSL) that speaks to just how important Light Emitting Diode (LED) lighting will
be to the collective energy futures of building owners across the United States.
Dr. Brodrick recently told the Tennessee-based Edison Report
that, "long life has been touted as a key advantage of LEDs, but
understanding and communicating how LED products fail and how long they last
can be challenging. The U.S. Department of Energy has come out with a new SSL
Technology Fact Sheet, Lifetime and Reliability, to help users gain a better
understanding of typical causes for LED product failures, the difference
between lifetime and reliability, and methods for measuring and reporting
lifetime and reliability."
The fact sheet points out that LED system performance is more
affected by interactions between system components than most conventional
lighting systems and the failure of any system component can lead to product
failure.
The DOE concluded that the dependence of LED package
performance on other components will continue to require that discussions about
lifetime be focused at the luminaire, and not component or even lamp level, as
lamp performance in different luminaires can vary. Additionally, as with many performance
attributes, LEDs have the potential to best other technologies in terms of
longevity, but choosing the right product requires some understanding of
expected failure mechanisms, lifetime, reliability, and serviceability, as well
as asking the right application-specific questions.
Dr. Brodrick notes that the accurate portrayal of LED product
lifetime and reliability is important for consumers, manufacturers, and the
lighting industry as a whole.
