Application of Color Light-Emitting Diodes in Automotive Exterior Lighting 2024-01-5003

Trends in automotive lighting are moving toward vehicle exterior lights, which will communicate with drivers and surroundings. The small size, lower power consumption, high efficiency, and substantially long life make LEDs a leading light source in automotive lighting applications. Losses in optical power for InGaN-based LEDs can be reduced up to 45% compared to AlGaInP, and phosphor-converted color LEDs can contribute to stable light output over the lifetime. Color LEDs will fulfill different requirements such as uniformity in color and luminance. Additionally, the mixing of different colors with white will underline the exterior features and aesthetic design of vehicles.
