This technology responded to the need for a solution to limit the front car critical position which led PSA to reduce the size of the headlamp space in comparison with the current 407. With such a constraint, Valeo was able to propose the NEO concept to insure the headlamp's feasibility.
Driving Vision News asked 3 questions to Arnaud Perrotin, in charge of R&D at Valeo Angers.
DVN : Could you tell us how did you achieve this new concept of lighting?
Arnaud: The bulb shield is replaced by an internal lens and there are 2 reflectors:
The inboard reflector close to the bulb sends most of the light to the internal lens in order to illuminate the foreground out to 50 meters. The outboard reflector illuminates the road beyond that distance. The result is a hot spot of more than 40 Lx (25,000 cd) with an illumination of around 40 Lx at 75R and a 1-lux spread of around 35° left and right.
DVN : Do you expect a great future of this concept?
Arnaud: We do think NEO concept is a groundbreaking concept that will have promising developments in the future.
It delivers high-level lighting performances for halogen bulbs and offers a clear styling differentiation. We are looking forward to get feedback from the Peugeot 508 release to confirm our strong expectations on this technology.
