Reconstruction of Illumination from Area Luminaires

This paper is concerned with the e cient reconstruction of illumination from area luminaires. We outline a 2-pass scheme; a lightpass, tracing ray bundles from the luminaires followed by a general eyepass ray trace phase. Special attention is paid during the rst pass to the reconstruction of shadows, both umbral and penumbral regions, for general luminaire geometries with no practical restricti...

Intelligent Lighting Control Using Correlation Coefficient between Luminance and Illuminance

An intelligent lighting system which provides required illumiancne at an appropriate location is proposed. This system does not have the centralized control device and also it is controlled by each intelligent lighting’s autonomous operation. Also the intelligent lighting system can contribute to energy saving. In this research, a new algorithm is proposed. For rapid converges it uses the corre...

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 ...
