Light in Transition

One word that characterizes the situation in the lighting industry during the recent years is “transition”. This transition to a new era is caused by changes in the symbiotic relationship between technological development, lighting design and, of course, sustainability principles. Lighting digitization together with the widespread use of LED lamps has led to increased device connectivity and interactivity offering a wide range of possibilities. LiFi, Internet of Things, Power over Ethernet and wireless sensors have transformed the traditional luminaires into smart devices capable to connect in a network transmitting information. As light is now enriched with information, it is possible to increase energy savings through smart controls and also to include additional functions, such as dynamic operation according to the users’ expectations and needs. The aforementioned developments allow not only the manipulation of a luminaire’s emitted luminous flux but also the color temperature of the light source. This is the core concept of the Human Centric Lighting which affects health, well-being and productivity, providing proper lighting when and where is needed. Fortunately, it seems that in this new era the focus of lighting design has just moved from spatial aspects to human aspects.

Furthermore, the use of artificial lighting in the built environment during nighttime can affect not only the visual performance and the wellbeing of humans, but also the environment. As architectural lighting is focusing into highlighting building facades and exterior areas, new formed legislations are trying to minimize the negative effects of the irrational use of artificial lighting. The lack of lighting design and energy consumption restrictions for exterior areas such as building facades, sports and recreation areas, have increased the use of lighting installations. Nowadays with the advent of energy efficient luminaires (LED) and state of the art lighting controls, the need for a better living environment should be promoted along with environmentally friendly lighting design techniques.

It is therefore of urgent importance that the new and often contradictory lighting trends are thoroughly examined and this is exactly the scope of this International Conference. IC-LIGHTS will try to highlight the role of lighting in the built environment, including the corresponding positive and negative issues that have recently emerged and document the current trends of lighting design for interior and exterior places. Case studies of highly remarkable lighting practices and exceptional lighting projects are also welcome.

Overall, the emerging developments on Lighting, Interactivity, Heritage, Health, Technology and Sustainability create specific skills and competences requirements for the human capital that works or would like to work in these areas. These topics are at the core of the ECOSLIGHT- Environmentally Conscious Smart Lighting EU-funded project (612658-EPP-1-2019-1-EL-EPPKA2-SSA). Therefore, one of the objectives of the conference is to contribute to the identification of those needs.

Call for papers

The conference invites submissions of extended abstracts (1000-1500 words) of work related to the conference themes discussing evidence-based, theoretical and conceptual research, as well as innovative case studies from both researchers and practitioners coming from different disciplinary backgrounds. Submissions will be reviewed by the members of the international programme committee and ranked on the basis of the originality of the research presented in relation to conference themes, clarity of presentation, the quality of the contribution made by the research, the validity and rigour of the methodology chosen, the significance of the results presented and the overall contribution to the understanding of archaeological practices in a changing world. The extended abstracts will form a book of abstracts that will be freely downloadable through the website.

An option for submitting short papers (3000-4000 words) after the Conference dates is also included. Successful short papers can form a discrete publication with ISBN depending on the amount of papers received. Authors that wish to submit a short paper will be notified for publication options at the Conference.

All submitted papers will be reviewed by experts in the field covered by the conference topics.
