As Se en at ITS A 2 01 3! Why Light Roadways? Among the chief reasons for installing roadway lighting, according to guidance from the Illuminating Engineering Society (IES, 2000), is the potential for lighting to contribute to improved nighttime safety. And the logic that roadway lighting provides drivers with improved visibility and in turn greater distance and longer time to respond to potent...
متن کاملEvaluation of Combination of Natural and Artificial Lighting Condition in Primary Schools (Case Study: Baneh City of Kurdistan Province, Iran)
Background & Aims of the Study: Promoting the health and safety is an important part of the fundamental mission of schools and one factor in designing and operating schools that always has been important is lighting. As students spend considerable hours in the classroom and school, lighting should be designed appropriately and in accordance with the standards, to protect them...
متن کاملRoadway Lighting Design Methodology and Evaluation
Theoretical methods are usually performed for ideal conditions to determine the illuminance and luminance but other design limitations should be considered in the real world. Also the visibility level is calculated by using background and target luminance under ideal conditions. In reality, there are many factors, which are very difficult to predict and include in lighting design equation. Huma...
متن کاملIntelligent Luminance Control of Lighting Systems Based on Imaging Sensor Feedback
An imaging sensor-based intelligent Light Emitting Diode (LED) lighting system for desk use is proposed. In contrast to the traditional intelligent lighting system, such as the photosensitive resistance sensor-based or the infrared sensor-based system, the imaging sensor can realize a finer perception of the environmental light; thus it can guide a more precise lighting control. Before this sys...
متن کاملHDR-VDP-2: A calibrated visual metric for visibility and quality predictions n all luminance conditions
Visual metrics can play an important role in the evaluation of novel lighting, rendering, and imaging algorithms. Unfortunately, current metrics only work well for narrow intensity ranges, and do not correlate well with experimental data outside these ranges. To address these issues, we propose a visual metric for predicting visibility (discrimination) and quality (mean-opinion-score). The metr...
