IN-LIGHT is a level 1 Collaborative project funded by the European Commission under the 7th Framework Programme which aims at contributing to the improvement of the passengers comfort through the development of a new concept of bifunctional aircraft window. This new concept combines two technologies, Electrochromism and Transparent OLED lighting (TOLED).

Electrochromism technology will allow the passenger to control the amount of heat and sun-light coming through the window, switching from a transparent colourless state to a deeply coloured transparent state. Additionally, a TOLED lighting system, also controllable by the passenger, will be integrated in the window offering a very innovative type of interior ambient lighting in the cabin, with novel aesthetic effects. The technologies to be used will introduce significant breakthroughs compared to the existing smart shading system such a low manufacturing cost, compatibility with plastic substrates, low power consumption and improved performance in terms of switching speed and cyclability/lifetime.

The new smart aircraft window to be developed within the IN-LIGHT project add significant value to conventional windows and will contribute to the passengers comfort enabling a tailored cabin environment regarding heat and light transmittance as well as ambient lighting according to their individual preferences.

Coordinated by CIDETEC this project brings together 10 partners from 6 different European countries plus one partner from Canada, all considered renowned research and industrial experts in their respective sectors. Starting from November 2012, the project is expected to be completed by October 2015.
