Abstract

This paper takes the Higbie-Levin daylighting studies and other illumination analyses using area-sources and corrects them using a new angular and rectangular equation. This new area-source equation points out the implementation deficiencies found in the Higbie-Levin equations of source plane and illuminance point by evaluating any arbitrarily located illuminance point without the need for multiple equations or superposition in either angular or rectangular forms.

Ce document reprend les études d'éclairage à la lumière du jour de Higbie-Levin et autres analyses d'éclairage utilisant le concept zone-source et les corrige en appliquant une nouvelle équation angulaire et rectangulaire. Cette nouvelle équation zone-source souligne les problèmes d'application relevés dans les équations Higble-Levin de plan-source et point d'éclairement en évaluant tout point d'éclairement arbitrairement choisi sans nécessité d'équations multiples ou de superposition en formes angulaires ou rectangulaires.

Este documento toma loa estudios de iluminación diurna de Higbie-Levin y otros análisis de iluminación utilizando el concepto de área-fuente. y los corrige aplicando una nueva ecuación angular y rectangular. Esta nueva ecuación área-fuente subraya los problemas de aplicación encontradas en las ecuaciones de Higbie-Levin del plano fuente y del pounto de iluminancia, evaluando cualquier punto de iluminancia seleccionado arbitrariamente sin necesidad de ecuaciones múltiples o de superposición en formas angulares o rectangulares.
