Lighting system with high power LEDs, light management structure, and large-area electronics in the LUMENTILE™ European Project

LUMENTILE™ (LUMinous ElectroNic TILE) is an EU funded project within the Horizon 2020 program. The goal of LUMENTILE™ is the development of a new product (called, in itself, "LUMENTILE™") to be brought to the market by year 2019: a luminous tile with novel functionalities, capable of changing its colour and interact with the user. Applications include interior/exterior tile for walls and floors covering, high-efficiency luminaries, and shows/advertising under the form of giant video screens. The integration of electronics and photonics technology inside a structure like the one proposed in LUMENTILE™ and their interaction with ceramic, represent the biggest challenge in the project. In this paper we will offer an overview of all the involved electro-optical elements, presenting the challenges and the design solutions to overcome them.
