The distribution of the illuminance has an important role to play in the development of new headlamps. As an alternative to the conventional methods of assessment, IAV has developed a bird’s-eye view technique intended to reduce the time and effort required while providing the necessary degree of precision.

Problem

Vehicle lighting is of tremendous significance for a brand’s characteristic design and makes an undisputable contribution to vehicle safety. Accordingly, interest in an evaluation system for headlamps in particular is on the increase. With these evaluation systems, assessment is in most cases based on isolux lines or the luminous flux in certain specific ranges. A standardised method has been published in CIE document TC4-45. Here, a headlamp’s beam pattern is determined as a single component on a photogoniometer and illuminance distribution on the road is computed by simulating light under fitted-headlamp conditions. This means that illuminance distribution is based on...
