Title Social Impact of Connected Landmark Lighting: A Social Sensing Approach Type Journal Article
Year 2020 Publication IEEE Internet of Things Magazine Abbreviated Journal IEEE Internet Things M.
Volume 3 Issue 1 Pages 64-67
Keywords Lighting; Society
Abstract The benefits of using light emitting diode (LED) lighting for landmarks extend beyond energy savings to the use of illumination for creating visual identity, placemaking, and increasing tourism. While measuring energy consumption is possible with metering technologies, thereby quantifying savings in energy costs, quantification of the social impact of landmark lighting is not straightforward. Measuring and monitoring social impact metrics is key to stakeholders investing in new connected LED lighting systems or upgrades of conventional lighting in order to realize the benefits of lighting that are beyond energy sustainability. We consider social sensing as an approach to quantifying social impact of landmark lighting. Using lighting at the Empire State Building and Bay Bridge as case studies, social sensing querying and data analytics aspects are presented. A number of practical lessons and technical directions for the use of social sensing in connected landmark lighting are then laid out.

Title Quantification assessment of light pollution of façade lighting display in Shenzhen, China Type Journal Article
Year 2020 Publication Optics Express Abbreviated Journal Opt. Express
Volume 28 Issue 9 Pages 14100
Keywords Lighting; Instrumentation
Abstract In this work, we investigated 39 façade lighting displays, all of which consisted of tri-chromatic light sources, namely blue-, green-, and red- light units, in Shenzhen, China. We extracted the spectral characteristics of the mean peak wavelength/full-width at half-maximum,and proposed universal spectral models. We further established the ‘chromaticity-performance’ relation to quantitatively assess the impact of light pollution on typical species based on corresponding action spectra. The findings provide a low-cost, fast and precise approach to assess light pollution of complicated light environment, and may help reduce energy waste and adverse environmental consequences associated with light pollution.

Title IoT-Enabled Light Intensity-Controlled Seamless Highway Lighting System Type Journal Article
Year 2020 Publication IEEE Systems Journal Abbreviated Journal
Volume in press Issue Pages in press
Keywords Lighting; Economics
Abstract Motivated by enormous highway-lighting energy consumption, smart lighting development is crucial to better manage available resources. While existing literature focused on ensuring cost-effective lighting, an equally important requirement, namely the visual comfort of motorists, is almost disregarded. This article proposes a novel Internet of Things-enabled system that can be intelligently controlled according to the traffic demand. Cooperative relay-network architecture is the central element that leverages upon placement of cyber-enabled lampposts to allow for sensing-exchanging highway traffic information. Data accumulation is exploited to automate adaptive switching on/off the lighting and provide backtracking detection of faulty lampposts. From the service provider’s perspective, we envision to deploy low-cost highly durable sensing and network components to significantly cut down the operating cost. From the road user’s perspective, the relay-network is envisaged to provide seamless driving experience where sufficient lighting is always perceived along the road. A critical analysis quantitatively evaluates the seamless driving experience considering car arrival rate, outage probability, and device malfunction probability. A road occupancy-based cost estimation analysis demonstrates the effective cost reduction of the proposal compared to existing systems. Furthermore, the performance of chosen communication modules under different setups is assessed through simulation, suggesting appropriate protocol for different highway traffic conditions.

Title Leaving lights on – A conscious choice or wasted light? Use of indoor lighting in Swedish homes Type Journal Article
Year 2020 Publication Indoor and Built Environment Abbreviated Journal
Volume in press Issue Pages in press
Keywords Psychology; Lighting
Abstract Promoting resource- and energy-efficient home lighting through technology and behaviour change requires an understanding of how residents currently use lighting and what they want from it. However, users' needs and desires relating to lighting in homes are poorly understood, as research is still limited. This paper aims to provide a fuller picture of residents' experiences with their home lighting. Interviews about how residents perceive the character of lighting and luminaires and lighting use suggest that home lighting has nine capabilities: to enable vision; to facilitate visual tasks; to display objects; to send a message; to support a particular atmosphere; to shape the architectural space; to offer a visual aesthetic experience; to maintain or change rhythmicity; and to evoke memories. Secondary data confirmed five of them. The identified capabilities relate to behavioural goals, psychological wellbeing and social needs. We conclude that seemingly wasted light in people's homes, i.e. lights left on in unoccupied rooms, can serve a purpose for the residents, such as avoiding visual or aesthetic discomfort, making the home inviting, benefitting people outside and providing safety. Findings have implications for the further development of new lighting technologies and design, energy-saving campaigns targeting residents and for urban outdoor environments.
