DISCUSSION CONCERNING THE LUMINANCE FROM MOTOR VEHICLE HEADLIGHTS

BETRACHTUNGEN ZUR LEUCHTDICHTETECHNIK BEI DER KRAFTFAHRZEUG-SCHEINWERFERBELEUCHTUNG

Conditions of visibility during the hours of darkness depend on the luminance and its distribution in the field of view. In the current methods of assessing lighting performance of motor vehicle headlamps there is a lack of quality criteria based on luminance parameters. The attempt is made to create an evaluation system for headlamps on the basis of luminance. This involves the fixing of the assessment range, definition of the quality criteria (mean luminance, longitudinal and lateral uniformity) and special density coefficients. The results of initial measurements are reported. /TRRL/
