Testing LEDs in a Climate Controlled Environment

Though they are a relative latecomer to the world of lighting technology, light-emitting diodes (LEDs) are quickly making up for lost time. Since their invention in 1962, LEDs have been applied in a wide range of lighting applications, including traffic signals, automotive panel lighting, aviation lighting, remote controls, DVD players and other household appliances, just to name a few. LEDs’ functionality and longevity have led to a substantial and growing market share. In fact, a recent study presented at the University of Chicago says that LEDs will capture 60 percent of the global lighting market over the next decade. However, in order to reach that market share, LED lighting devices are subject to an important technical challenge – consistency in the brightness and quality of the light emitted from LED bulbs.
