AN INNOVATIVE ultra-minimalistic LED luminaire has been installed in the library of a Danish university.
The Tracy radical linear system was created by LED iBond and uses the unique properties of aluminium composite plates to integrate LEDs into an ultra-slim, ultra-efficient package.
It consists of two thin layers of aluminium, bonded by a PE core, resulting in an overall thickness of just 6mm.
At the Technical University of Denmark’s (DTU) Smart Library, the numerous traditional light fixtures have been replaced with the Tracy which varies the colour temperature as well as light intensity depending on user needs and time of the day.
The library at is the heart of the student environment at the campus, just north of Copenhagen and occupying more than one square kilometre.
Here the 11,000 students study and meet in project teams around the clock.
DTU wanted the users of the library at a later stage to be able to interact and change the lighting in the individual areas, while at the same time achieving significant energy savings.
As the extensive rebuilding included brand new ceilings and a new ventilation system, the Tracy was customised to the construction of the building and the needs of the users.
It’s now installed on three floors of the library and includes three kilometres of light rails and 7,250 LED spots.
The light installation can be regulated in brightness and colour temperature during the day.
The aim is to create the most suitable conditions in relation to the needs of the users and to follow the daylight throughout the day.
This means that the light is more warmer in the morning, becoming cooler at mid-day and again changes to a warmer light at the end of the day.
The luminaires are divided into zones based on where the students and the administrative staff are located.
In the zones where students are reading, talking or working in teams, the luminaires are designed in two parallel Tracy lighting rails with two sets of LED, with different colour temperatures, to establish both a natural light and a focused reading light.
In the outer zones and the walking zones the lighting rails are mounted individually and are dimmed based on the incoming daylight.
The project establishes an infrastructure for a future IoT Living Lab.
The focus is to achieve an optimal indoor climate, which covers lighting in the same way as heating, ventilation and sound, and hereby testing the different technologies for an optimal interaction.
LED iBond recently appointed Light on Line as its London and South East distributor in the UK.
