Optoelectronic technologies for lighting in automotive: state-of-the-art and perspectives

This article explores the advancements and potential of LED (Light Emitting Diode) based lighting, adaptive front lighting (AFL), laser lighting, and organic light¬emitting diode (OLED) technologies in automotive applications. AFL systems, using matrix LEDs and advanced sensors and control mechanisms, dynamically adjust the headlight beam pattern to optimize visibility and safety in various driving conditions. The development of the LED package allows an easier and efficient integration in new lighting systems. The benefits of AFL systems based on Digital Micromirror Devices or LED matrix not only improve illumination range while reducing glare, but also enhance communications and awareness of the vehicle on the road. Laser lighting offers high-intensity illumination, longer reach, and is able to provide higher energy efficiency when high luminance is needed. OLED technology, with its thin, flexible, uniform, and segmented light sources, represents an exciting opportunity for automotive lighting design and dynamic communications. In this work we will summarize the current status of innovations in automotive lighting underlying their strengths, weaknesses, future prospects, and opportunities.
