Title Analysis of light pollution from floodlighting: Is there a different approach to floodlighting? Type Journal Article
Year 2017 Publication Light and Engineering Abbreviated Journal
Volume 25 Issue 1 Pages 75-82
Keywords LED lighting
Abstract The research which was prepared for this paper was inspired by a real floodlit object. The main distinctive feature is connected with the directionality of its lighting. The „Sezam” building was one of the first to be illuminated in the opposite way to the usual manner of floodlighting. The analysis, based on the measurement of horizontal illuminance on the pavement in front of the building andof theluminance on the facade, leads to some very unusual conclusions. It goes deeper than merely the assessment of the phenomenon of light pollution in the context of floodlighting. Additionally, a short survey about the preferences of lighting directionality in floodlighting and the general concept of light pollution was conducted on a group of over a dozen people. It turned out that people are quite aware of the phenomenon of light pollution and they rather prefer illumination from floodlighting to be from bottom to top.

Title Several biological benefits of the low color temperature light-emitting diodes based normal indoor lighting source Type Journal Article
Year 2019 Publication Scientific Reports Abbreviated Journal Sci Rep
Volume 9 Issue 1 Pages 7560
Keywords Human Health; Lighting
Abstract Currently, light pollution has become a nonnegligible issue in our daily life. Artificial light sources with high color temperature were deem to be the major pollution source, which could induce several adverse effects on human's health. In our previous research, we have firstly developed an artificial indoor light with low color temperature (1900 K). However, the biological effects of this artificial light on human's health are unclear. Here, four artificial lights (1900 K, 3000 K, 4000 K and 6600 K) were used to evaluate some biological changes in both human (in total 152 person-times) and murine models. Compared with other three high color temperature artificial lights, our lights (1900 K) presented a positive effect on promoting the secreting of melatonin and glutamate, protecting human's eyes, accelerating would healing and hair regeneration. These systematical studies indicated that the proposed low color temperature (1900 K) light could provide several significant benefits in human's daily life.

Title Light affects heart rate's 24-h rhythmicity in intensive care unit patients: an observational study Type Journal Article
Year 2019 Publication Nursing in Critical Care Abbreviated Journal Nurs Crit Care
Volume 24 Issue 5 Pages 320-325
Keywords Lighting; Human Health; Heart Rate; ICU; Circadian Rhythm
Abstract BACKGROUND: Intensive care unit (ICU) patients experience two affronts to normal 24-h rhythms: largely internal events such as medication and external factors such as light, noise and nursing interventions. AIMS AND OBJECTIVES: We investigated the impact of light variance within an ICU on 24-h rhythmicity of three key physiological parameters: heart rate (HR), mean arterial blood pressure (MAP) and body temperature (BT) in this patient population. DESIGN: Patients were assigned to beds either in the 'light' or 'dark' side within a single ICU. An actigraph continuously recorded light intensity for a 24-72-h period. METHODS: Measurements of HR, MAP and BT were recorded every 30 min. RESULTS: HR, MAP and BT did not follow 24-h rhythmicity in all patients. Higher light exposure in the Light Side of the ICU (122.3 versus 50.6 lx) was related to higher HR (89.4 versus 79.8 bpm), which may translate to clinically relevant outcomes in a larger sample. Duration of stay, the one clinical outcome measured in this study, showed no significant variation between the groups (p = 0.147). CONCLUSIONS: ICU patients are exposed to varying light intensities depending on bed positioning relative to natural sunlight, affecting the 24-h rhythm of HR. Larger, well-controlled studies also investigating the effect of relevant light intensity are indicated. RELEVANCE TO CLINICAL PRACTICE: Light is a variable that can be manipulated in the constrained environment of an ICU, thus offering an avenue for relatively unobtrusive interventions.

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.
