AN006 Reliability and lifetime of LEDs

of customer expectations over the expected lifetime. In other words, the LED does not fail during its lifetime under the given environmental and functional conditions. The reliability of the products is thus based on the chain of the materials, the manufacturing process and the function of the component (Figure 1).
