Title IoT-Enabled Light Intensity-Controlled Seamless Highway Lighting System Type Journal Article
Year (down) 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 (down) 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.

Title Lighting for Heritage Building: A Case Study of the Lighting Design Applied on St. George’s Church in George Town, Penang Island Type Journal Article
Year (down) 2020 Publication Awang M., Meor M Fared M. (eds) ICACE 2019. Lecture Notes in Civil Engineering Abbreviated Journal
Volume 59 Issue Pages 113-119
Keywords Lighting
Abstract Light is one of the critical aspects of architecture, yet it is one of the understated elements in our daily lives. Light has a significant spot to form events, activities, and memories. Scientific studies have shown that appropriate and proper lighting does not only affect human health but daily human moods as well. Nowadays, lighting fixtures play essential roles in architecture and markets. A proper lighting fixture helps to highlight the structure, textures, and form of the shape of a building. However, the designers tend to focus more on the art aesthetics rather than the conservation ethics, such as the colorful design and the attractive lighting fixtures on the building, while the prime concern should be on realizing the impact of the lighting fixture toward the environment. The objectives of this study are to highlight the issues of the lighting system of the heritage building and suggest some recommendations to meet the requirements for the heritage building for better lighting design. The data for this research was collected using the quantitative method. Thus, as a result, it is found out that lighting design highlights the historical building, and therefore, attracts tourists, which benefit the economy. However, improper lighting installation leads to a negative impact on the society and human health.

Title A Research on the Improvement of Visibility Using Low Deck Lighting in Bad Weather Type Journal Article
Year (down) 2020 Publication Journal of the Korean Institute of Electrical and Electronic Material Engineers Abbreviated Journal
Volume 33 Issue 3 Pages 186-193
Keywords Lighting
Abstract We investigate a fog-detection CCT control system using low deck lighting as a solution to the forward visibility of pole-type street lamps employed on existing roads. The lighting standards were met with a light source that has less compared with those of pole-type street lamps. The results show that the transmission rate was increased by changing the color temperature by automatically recognizing fog in bad weather and minimizing the phenomenon of lighting. In addition, it was allowed to create a safer and more comfortable driving environment for drivers owing to flicker or light pollution of existing pole-type street lamps. As a result, if lighting is used at a lower level than pole-type street lamps, the accident rate caused by securing the driver's forward visibility can be reduced sharply and existing problems can be resolved.
