Event Details

On 8 December 2015, the Intelligent Lighting Institute (ILI) of Eindhoven University of Technology (TU/e) organises the 2015 edition of its annual public outreach event. During this event we highlight recent developments in responsible research & innovation in science & technology in light & intelligent lighting and its applications in health & well-being.

During the event the audience will also be able to get better informed about recent, current, and upcoming research & innovation projects carried out by researchers related to ILI by means of a series of poster presentations

Program (Updated)

10:00   Registration with coffee/tea in Building "De Zwarte Doos", Flimzaal (Floor 1) at TU/e Science Park 

10:30   Opening & welcome
by prof. dr. I.E.J. (Ingrid) Heynderickx, scientific director of ILI

10:45   Invited talk entitled "Analogies between descriptions of light in optics, perception and design"
by dr. S. (Sylvia) Pont of Delft University of Technology

There is no vision without light and without proper light we simply cannot see certain material, shape and space characteris-tics. But what is proper light? We usually do not look at light sources, but at objects. Thus, I focus on appearance instead of lamps. Knowledge about appearance is limited to matte, glossy and translucent materials, but our world consists of more than plaster, plastics and glass. To design proper light we need fundamental understanding of the mechanisms underlying appear-ance at the spatiotemporal scales of human vision. The range of materials, shapes, spaces and available lighting technologies is endless and all affect the resulting light distributions (so-called “light fields”) and appearance of objects in it. I propose to approach this problem via limited sets representing key features in the visual information. In our research we demonstrated the feasibility of an approach in which we used so-called “canonical modes” in the optical structure, or components that rep-resent key components in the visual information, for light fields as well as materials. I also demonstrated the analogies be-tween such perception-based representations in physics, perception and design in theory, experiments and applications. This allows us to describe, measure, visualize and apply light as such and study its effects on material and shape perception. I will explain the three main components of our research: extending the fundaments with theory and methods to describe, meas-ure, and visualize light; empirical testing and framing of its visual effects on material, shape and space appearance; and doing scientifically informed design of intelligent lighting systems.

11:15   Presentation on research program "Light by Design"
by dr. J.H.M. (Jan) ten Thije Boonkkamp, program manager

11:35   Series of poster pitches related to relevant research & innovation projects

12:35   Lunch (in parallel with poster presentations)

13:40   Invited talk entitled “A new Colour Appearance Model for Unrelated Colours
by prof. dr. P. (Peter) Hanselaer of KU Leuven, Light & Lighting Laboratory

In a series of psychophysical experiments the brightness, hue and “amount of white” perception of unrelated self-luminous stimuli was investigated. Based on the experimental visual data, a new colour appearance model for unrelated self-luminous stimuli, CAM15u, was developed. It was found that, despite its simplicity, CAM15u performs as well or better than other, more complicated, CAMs. Furthermore, the brightness perception of different sized, unrelated self-luminous stimuli was investigat-ed. A significant effect of stimulus size on brightness was found, effectively modelled by a simple power function. The de-pendence of brightness on stimulus size was incorporated into the brightness prediction of the CAM15u model. It has been shown that the model can be a valuable tool to improve existing standards and guidelines describing the requirements for traffic signs, LED billboards, etc.

14:10   Presentation on research program "Bright Environments"
by dr. T. (Tanır) Özçelebi, program manager

The research within the Bright Environments research program is fuelled by the need to make the leap towards truly intelli-gent lighting systems. In planning and carrying out our research, we approach lighting systems from various perspectives of multiple stakeholders, ranging from end-users, application developers and people that need to maintain such a system to platform developers and device producers. This presentation will give the audience an overview containing some of the most interesting work that is currently being done by the members of the research program, with some highlights from 2015.

14:30   Presentation on research program "Sound Lighting"
by prof. dr. ir. Y.A.W. (Yvonne) de Kort, program manager

14:50   Break (in parallel with poster presentations)


Invited talk entitled "Healthy Environments in Offices: Living at The Edge"
by prof. Dr.-Ing. A.L.P. (Alex) Rosemann and prof. dr. ir. E.J. (Evert) van Loenen

Two recently started research projects in the research line of “Creating Healthy Environments” will be described. They focus on improving comfort, health and safety using smart and innovative designs and solutions for the built environment in hospital and office environments respectively. Solutions for healthy environments will not result from optimizing singular aspects but from a holistic approach considering multiple contributing parameters.

The overall objective of the hospital project is to gain more insight into the relation between lighting conditions on one hand, and user well-being as well as their performance in a hospital environment. The focus is mainly on staff members but will include investigations with patients as well. The expected results from this research project are addressing this lack of consideration but identifying the impact factors on the health care staff satisfaction. Recommendations derived from the research results will inform the design process and help guiding the design towards a healing environment that has a positive motivating effect on staff leading to for instances shorter hospital stays of patients and reduction of medical errors. The research is being carried out by 2 PhD students (one focusing on lighting and the other on acoustics).

The focus of the office project is on the interaction of staff with the lighting system and on their usage of the office environment. The connected lighting system of Philips which is being used in the new office building “The Edge” allows retrieving anonymous data on the usage and interaction with the lighting and climate system. Its impact on the health and well-being of workers as well as the overall strategy for efficiently operating these end uses form the research carried out by a total of 4 PhD students. The expected results and insights will contribute to recommendations for enhancing the effectiveness of a lit office environment without negatively impacting the well-being and motivation of staff.

15:40   Presentation on creative program "Openlight"
by R.V.A.Q.A. (Rombout) Frieling M.A., M.Sc., program manager

16:00   Presentation on research infrastructures and Living Labs
by dr. ir. P.H. (Elke) den Ouden, dr. ir. P.R. (Philip) Ross and dr. ir. A. (Antal) Haans

16:20   Short walk (< 5 minutes) from Building De Zwarte Doos to Building MetaForum


Reception and networking with as of 17:00 the festive opening of new Living Lab
by prof. dr. ir. F.P.T. (Frank) Baaijens, Rector of Eindhoven University of Technology

The new intelligent lighting research infrastructure annex Living Lab at “De Markthal” is a state-of-the-art infrastructure of sensors (e.g. cameras) and actuators (e.g. lights) that is accessible via an open ‘Internet-of-Things’ architecture and that serves the research purposes from various de-partments of TU/e as well as various education programs on B.Sc., M.Sc. PDEng and PhD level. This infrastructure is not only used for research related to light & lighting (in the “Sound Lighting” program), but also for research related to ‘Internet-of-Things’ based system and software architectures for digital lighting infrastructures (in the “Bright Environments” program).

18:00   (Closed)

TU/e Intelligent Lighting Institute

The TU/e Intelligent Lighting Institute (ILI) was established in 2010 to investigate novel intelligent lighting solutions that will become within our reach by the large-scale introduction of LED technology, with a special emphasis on how these new solutions might affect people. We do this in collaboration with departments of the TU/e and partners in the public and private sectors. The lighting research performed at ILI is producing unique know-how and a technological head start for the participating parties, the Brainport Region, and as part of Europe.
