Title Half a century of Lighting Research & Technology: A bibliometric review Type Journal Article
Year 2019 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology
Volume in press Issue Pages 1477153519857788
Keywords History; Lighting; Review
Abstract Lighting Research & Technology (LRT) is an influential journal in the field of light and lighting dating back to 1969. To celebrate its 50th birthday, the current study explored its bibliometric characteristics and mapped the bibliographic information graphically through VOSviewer software. This analysis found that the number of papers has steadily increased during recent years. The most productive and cited country was the United Kingdom. The most productive and cited institution was Rensselaer Polytechnic Institute. The most prolific author was Steve Fotios and the most cited author was Mark Rea. The journal most cited together with LRT was Leukos. LRT has become more and more international and interdisciplinary over the last five decades. Suggestions for the development of LRT are provided. Develpoments over the last 50 years have turned LRT into one of leading journals in the light and lighting field, one which has a bright future.

Title Evaluation method and reduction measures for the flicker effect in road lighting using fixed Low Mounting Height Luminaires Type Journal Article
Year 2019 Publication Tunnelling and Underground Space Technology Abbreviated Journal Tunnelling and Underground Space Technology
Volume 93 Issue Pages 103101
Keywords Lighting; Vision
Abstract Low Mounting Height Luminaires (LMHL) are used in many cities on viaducts, cross-sea and cross-river bridges due to their unique advantages. However, the flicker effect is an important factor that needs to be considered in road lighting using fixed LMHL. At present, there are not many researchers in the field of international lighting. Previous types of road lighting design were based on the method of the tunnel lighting flicker effect. At the same time, the flicker effect is mainly based on the subjective feelings of people but is not quantified. In this paper, the Flicker Index (FI) is calculated by measuring the parameters of streetlamps to evaluation flicker effect. Secondly, the suggestion to offset the flicker effect in CIE 88-2004 “Guide for the Lighting of Road Tunnels and Underpasses” is to limit the speed of the vehicle and adjust the road light spacing to avoid the flicker sensitive area on human eyes, while ignoring the essential problem of how the flicker effect is generated through the energy level of the stimulating optical signal. Two factors affecting the strength of the flicker effect are proposed: energy ratio and duty cycle. The duty cycle, in time, refers to the proportion of the strong and weak flashing signals during the period; in space, it refers to the proportional relationship between the length of the luminaire and the distance between the lamps, which is related to the running speed of the vehicle. It is consistent with the CIE recommendations for flicker. Thirdly, the essence of the flicker effect is the problem of the energy level of the stimulus signal. This study investigated the reduction in the brightness of the light source, hence reducing the energy of the visual stimulation signal to the human eye in order to judge the degree of fatigue in human vision. The experimental results show that the degree of fatigue in human vision decreases when the brightness of the experimental light source decreases. Therefore, the key to changing the flicker effect of LMHL is to reduce the contrast between the surface brightness of the luminaire and the brightness of the spatial background.

Title Analysis on Luminance of Outdoor Signboards of Commercial Areas in Seoul at Night Considering Light Pollution Type Journal Article
Year 2015 Publication Journal of The Korean Society of Living Environment System Abbreviated Journal J. Korean Soc. Living Environ. Sys
Volume 22 Issue 4 Pages 583-595-589
Keywords Lighting; Light pollution; Commercial areas; Night-time lighting; Outdoor Signboards; Luminance; outdoor lighting; artificial light at night; signs; LED signs; LED billboards
Abstract As the city is commercialized, the number of stores is increased and it also makes outdoor billboards’ number increased accordingly. And signboards on the street make pedestrians unpleasant, making light pollution by light reflection. In this study, we measured the luminance to target the outdoor signboards of commercial area in Seoul. On the basis of the obtained results, the External system showed high luminance values, and the luminance values of Letter-type system were lower. Furthermore, the measured value at the midnight time was higher, and we considered that the more floating population bring about the high luminance value of the External system. The signboards of External system should be avoided, the Letter-type system should be recommended.
