This paper presents electricity utilization and saving potential assessment for residential lighting demand side management program. The assessment involves combined Baseline Energy Use method and Analytic Hierarchy Process which represent technical and customer preference approaches, respectively. Residential lighting load curve and lamps’ share of ownership are estimated based on the first me...

The production of high quality animations which feature compelling lighting effects is computationally a very heavy task when traditional rendering approaches are used where each frame is computed separately. The fact that most of the computation must be restarted from scratch for each frame leads to unnecessary redundancy. Since temporal coherence is typically not exploited, temporal aliasing ...

In China, the manufacturing of lighting products is very labour intensive. The approach used to check quality and control production relies on operators who test using various types of fixtures. In order to increase the competitiveness of the manufacturer and the efficiency of production, the authors propose an integrated system. This system has two major elements: a com...

We are doing research and development of an intelligent lighting system. In the intelligent lighting system, the algorithm which controls lighting fixtures is important. In this research, we examine how to grasp the position relation between the lighting and the illuminance sensors with sufficient accuracy, and we propose a lighting control algorithm which estimates accurate position relation b...

Accurate assessment of people's preferences for different outdoor lighting applications is increasingly considered important in the development of new urban environments. Here a new method of random environmental walking is proposed to complement current methods of assessing urban lighting applications, such as self-report questionnaires. The procedure involves participants repeatedly walking b...

Lighting design plays a crucial role in indoor lighting design, computer cinematograph and many other applications. Computer-assisted lighting design aims to find a lighting configuration that best approximates the illumination effect specified by designers. In this paper, we present an automatic approach for lighting design, in which discrete and continuous optimization of the lighting configu...
