The EARTO Innovation Awards 2016 was presented in Brussels, Belgium, by Jyrki Katainen, European Vice-President for Jobs, Growth, Investment and Competitiveness. LED light bulbs last longer and offer better light quality than any other types of traditional lighting. Replacing all traditional lighting with LEDs would reduce Europe's energy consumption by 9 % saving 65 billion of dollars and avoiding 42 tons CO2e per year. Today, their use is limited because of their high costs.
Leti and Inac teams joined effort to develop an affordable technology called wireLEDTM. Researhers developed a larger and cheaper to facilitate high volume production at low cost. In fact, materials used reduces by two third current 2D LEDs material cost. Furthermore, while 2D LEDs need specific manufacturing requirements, this new technology is fully compatible with existing silicon foundries. On balance, 3D LEDs should be about four times cheaper to produce than regular LEDs.
In going 3D, LEDs produce three times more light with lower risk of defects. This technology also follows the advanced semiconductor industry which makes 3D LEDs easy to integrate with existing electronics. Furthermore, while today's LEDs require expensive phosphors to produce white light - reducing efficiency levels - 3D LEDs are phosphor-free and offer better performances, such different types of color temperature and multi-coloured light.
- Opening up a wide range of possibilities
These LEDs can be deployed anywhere - at home, in public buildings or cars. So far, Ikea and Valeo have already shown interest in this technology.
