Lighting uniformity is a key factor in traffic safety, and it could even result in energy savings for light installations. However, highly uniform horizontal road lighting for motorized vehicles may not be optimal for pedestrian roads. Therefore, it is important to evaluate the way in which pedestrians experience road lighting uniformity. Accordingly, we employed a qualitative approach to examine pedestrian road lighting uniformity. Visual analyses were used to exemplify and discuss the perceived uniformity. The case studies were performed on three pedestrian roads with similar light installat

Road lighting uniformity is an essential lighting quality parameter for motorists and pedestrians and varies with lighting design parameters. Increased road lighting uniformity may result in benefits, such as increased reassurance and perceived safety for pedestrians or an increased overall visual perception. However, no previous study has investigated how road lighting uniformity varies with lighting design scenarios or how the uniformity of various lighting design scenarios affects other essential parameters, such as energy performance and obtrusive light.

Modern high-accuracy light microscopes use the lighting system proposed by August Koehler which provides full and uniform lighting of studied objects. However, such lighting systems have large dimensions. In light of the global trend towards minimisation of instrument dimensions, this work consisted of reduction of the size of a Koehler type lighting system: calculations were made for light source and CCD selection; such components of the lighting system as collector and condenser were designed for minimum of spherical aberration; uniformity of illumination of a studied object was assessed.

Even distribution of natural light is crucial in creating optimal visual comfort in classrooms. Many classrooms in tropical areas experience lighting imbalances, with areas near windows receiving excessive light, while others lack lighting. This study aims to evaluate the effectiveness of passive design strategies in improving the uniformity of natural lighting through a computational simulation approach. The research subjects include elementary, junior high, and senior high school classrooms in Makassar City, South Sulawesi. Modeling was conducted using Ecotect Analysis 2010 software, compari

In order to improve the comfort of classroom users and improve the lighting environment of university classrooms, this paper puts forward different optimization schemes based on computer simulation. Dialux, a lighting environment design software, is used to numerically simulate the lighting environment of university classrooms. The classroom lighting scheme is optimized and different solutions are proposed. Through computer simulation, the effect of lighting is compared and analyzed, in order to find the most beneficial scheme for students’ mental health, which provides the basis for intellige

Artificial lighting is a crucial component of office environments and a significant energy consumer. Effective lighting design in offices must balance the well-being and visual comfort of workers with energy efficiency. Therefore, designers need more focus on lighting design for providing more eye-comfort space for workers who spend most of their time in office. This study examines various artificial lighting distributions and fixtures concerning their potential for energy savings and visual comfort. Utilizing a quantitative research approach, both literature review and simulations were conduc

A good lighting environment for roads at night is essential for traffic safety. Accurate and timely knowledge of road lighting quality is meaningful for the planning and management of urban road lighting systems. Traditional field observations and mobile observations have limitations for road lightning quality evaluation at a large scale. This study explored the potential of 0.92 m resolution JL1-3B nighttime light remote sensing images to evaluate road lighting quality in Nanjing, China. Combined with synchronous field measurements and JL1-3B data, multiple regression and random forest regres

The artificial lighting level and visual comfort of drivers for a high-speed train cab are evaluated by using computer simulation technology. The simulation model is established first, and then some lighting quality indexes, such as illuminance, illuminance uniformity and glare, are analyzed based on related design standards. Considering the effects of environmental lighting on drivers physiology and psychology, the analysis on environmental psychology for driver of the cab are conducted also. The evaluation method proposed in the paper is significant for improving artificial lighting design o

In addition to supporting visibility, parking lot lighting should enable people to feel safe and secure while they are walking through a parking lot at night. Previously published research has indicated that perceptions of safety and security under outdoor illumination are correlated with perceptions of scene brightness, which in turn are influenced by the light level in the lot, by the spectral distribution of the illumination, and the uniformity of illumination. However, the interactions and interplay among these factors are not well understood. To address this knowledge gap, two laboratory

Abstract Multi-spectral imaging is commonly used in biomedical field to detect and recognize targets, which are in a low contrast with their background. Highly integrated multichannel light-emitting diode (LED) devices enable tuning the spectral contents of the illumination in an accurate and compact fashion, and hence make multi-spectral lighting more easily achievable even in a microscope. Besides the light source, the light mixing system is also a key to realize it. Existing light mixing devices available for multi-spectral LED lighting systems are both costly to manufacture and intricate i

The use of skylights in buildings introduces natural light into the interior space, thereby reducing the reliance on artificial lighting and aligning with the principles of low carbon and environmental sustainability. To ensure optimal indoor lighting quality, it is essential to optimize the arrangement of skylights to strike a balance between high average illumination and uniformity of illumination.
