Doubling driver visibility with laser-based headlights

CS International 2016; 1,2 March 2016, Brussels, Belgium

At CS International 2016, BMW's Abdelmalek Hanafi will be presenting a paper on 'Doubling driver visibility with laser-based headlights'. 

This will be one of 34 presentations spanning five sectors delivered by industry-leading insiders at the international conference on compound semiconductor devices which will be held on the 1st and 2nd March 2016, Brussels, Belgium.

These talks will detail breakthroughs in device technology; offer insights into the current status and the evolution of compound semiconductor devices; and provide details of advances in tools and processes that will help to drive up fab yields and throughputs.

Hanafi's presentation will look at how modern vehicular lighting systems (VLS) are intended to improve safety on the road by providing the adequate visibility to the drivers under different driving conditions from within a compact housing, whilst simultaneously reducing the impact on the environment and meeting the consumer demands in terms of styling and low cost. 

Using high-power GaN-based blue laser diodes that pump a yellow phosphor in a remote position, BMW developed a new high-brightness white point-like source having a peak brightness of over 1000 cd/mm², which is ten times than that of high-power white LEDs. By integrating this new light source in a VLS, BMW was able to double the range of the visibility while increasing the VLS's efficiency, keeping its size compact and fulfilling the required light fluxes and intensities. 

This illumination method is not restricted to the automotive sector, but it can be generalised to sectors, where efficiency and compactness and/or specific lighting distributions are required.

Keynote presentations at the conference will include:

James Klein (Qorvo) At the core of 5G
Daniel Fernandez:  EU Project SPEED (Silicon carbide wide band-gap devices for energy applications)
Abdelmalek Hanafi (BMW): Doubling driver visibility with laser-based headlights
Yanning Sun (IBM):  III-V/Si integration: Moore and more
Carlos Algora (Technical University of Madrid):  Perspectives of concentrator photovoltaic technology
