DVN publish today the report on SAE Show. As a sample, we reproduce a part of one of the lectures. It is the lecture of Rainer Visteon from Visteon, who presents a new LED headlamp with low beam, high beam and DRL.
The multifunctional design achieves an optimum balance between requested light performance and challenges to reduce power consumption and offer a styling differentiation
General features of the headlamp
Optical system efficiency >60%
LED low beam lighting performance
The low beam is very homogeneous and widely spread.
Hot Spot = 32 Lx
Luminous Flux = 618 Lm
Lighting output between halogen (300Lm-500Lm) and HID (800Lm-1,200Lm)
Low beam reflector : Butterfly concept
LED high beam lighting performance
The beam is very contrasted in order to get the best visibility
The efficiency is around 67%
Hot Spot = 98 lx
Luminous Flux = 673 lm
Two Concepts are developed to answer styling and packaging requests:
