LUMINANCE-BASED EVALUATION INDEX FOR NON-UNIFORMITY OF LIGHTING ENVIRONMENT

A Quantitative Evaluation Method for Luminance Non-uniformity of a Large LED Backlight

This report describes a quantification method for luminance non-uniformity of a large LED backlight. In experiments described herein, participants subjectively evaluated artificial indistinct Mura images that simulated luminance non-uniformity of an LED backlight. We measured the luminance distribution of the Mura images. Then, the measured luminance distribution was converted into S-CIELAB, in...

Luminance Metrics for Roadway Lighting

Road lighting and headlights: Luminance measurements and automobile lighting simulations

This paper focuses on lighting dimensioning and lighting quality of traffic lighting. The work considers the factors that are important in creating optimal lighting conditions and luminous environment for night-time driving. The work is based on simulating, measuring and analyzing traffic lighting. The work introduces a new method for road luminance measurements and analysis. For simulation of ...
