Lumen Effectiveness Multipliers For Outdoor Lighting Design
Perhaps one of the most fascinating and important subjects to be addressed in our industry over recent years is the effect of lamp spectral distribution on visibility. In the past, it has been widely accepted that under virtually all circumstances where artificial light is used, lighting level calculations could ignore spectral effects. In IESNA and CIE practice, recommended lighting levels do ...
متن کاملLamp Color and Visibility in Outdoor Lighting Design
Figures for the United States indicate approximately 40,000 road fatalities per year. Per 100,000 miles driven, the nighttime accident rate on unlighted highways is roughly three times that during daylight hours. While this is partly alcohol and fatigue related, the major factor is believed to be the reduced visual performance of the driver under night conditions. Statistics for other countries...
متن کاملHierachical Lighting Simulation for Outdoor Scenes
Lighting algorithms for outdoor scenes suffer from the sheer geometric and lighting complexity of such environments. In this paper we introduce an efficient, hierarchical solution to the problem of outdoor illumination. Data structures and sampling algorithms are presented, permitting the integration of complex and natural objects in a hierarchical radiosity simulation system. This new approach...
متن کاملComputer-assisted lighting design and control
This dissertation shows that computer-based lighting control systems can support the lighting design process considerably better than traditional consoles. It describes the Lula Project, a new software package for lighting design and control, that implements this level of support. Lula’s focus is on the conceptual ideas behind a lighting design rather than the concrete lighting fixtures used to...
