課程簡介

As LEDs are gradually setting standards in automotive head-lighting, we already have seen examples of laser headlamps touted as the future of high end automotive lighting. A diode laser pumped remote phosphor based white light source can much better than LEDs in terms of luminance and design flexibility. Diode lasers need smaller optics and hence, can offer sleek and unprecedented design possibilities.

However, the 445 nm commercial blue laser diodes have a limited external quantum efficiency in the range of roughly 30% and heat management is a crucial issue for stable performance and durability.

Also, the remote phosphor module is a very important component of the so called laser headlamp and the selection of the phosphor depends on its optical and thermal properties. This talk will focus on some latest developments and highlight the potential and challenges of laser headlamp technology.
