Abstract

With the continuous development and improvement of human factors lighting research, while satisfying the functional lighting of indoor spaces, people are pursuing more breakthroughs and innovations in lighting quality for health. Expanded from the traditional work surface illuminance to the spatial light distribution. This study proposed a new evaluation parameter for indoor lighting environment named as BI (Brightness Index), proposed B_av(Average Brightness) and U_B(brightness uniformity) to measure the brightness and the chiaroscuro of the indoor lighting environment. Taking the classroom as an example, the accuracy and feasibility of the parameters were verified through on-site testing and simulation. Results shew the effectiveness and application potentiality in lighting design and evaluation, can well complement and improve the current lighting environment evaluation system.
