Reliability Management of a Light-Emitting Diode for Automotive Applications

Abstract

In the last years, the automotive industry are using more and more light-emitting diodes (LEDs) in automotive interior and exterior applications such as dashboards, ambient lighting, rear-turn indicator, daytime running light and headlamps. Safety applications like drowsy driver warning or night vision systems are meanwhile already established in the midsize premium car segment. Not only visible LEDs but also infrared (IR) emitting LEDs and visible laser components are demanded from the market for new innovative light designs. Especially the design of headlamps and rear lights is established as distinctive feature for car set maker. The focus in this chapter is to give an overview about the reliability management for automotive LEDs and explain the benefits for automotive industry to get full support from LED manufacturer.
