Abstract

The visual tasks consist in perception of presence (detection) of objects. If the luminance of the object to be detected is high enough (related to its environment) to achieve 99% detection probability at a distance that is longer than the stopping distance of the vehicle accidents can be avoided. The state of the art in front lighting systems are adaptive driving beam) modules using LED pixels. Developing efficient glare free high beam systems is on the one hand to eliminate glare by dimming luminous intensity, on the other hand to increase the luminous intensity and thereby the visibility of the visual field of the driver. Hence, the question to be asked is, how the light intensity for every angle segment (pixel) should be defined in order to prevent glare, and more importantly, to detect the objects for relevant eccentricities with a high probability.
