Consumerizing Solid State Lighting (CSSL) is an Eniac Project.

LED (Light-emitting diodes) lamps are a fast emerging technology which is considered as the true alternative to the Compact Fluorescent Lamp (CFL). Many commercial products are now available for professional application; however there is rarely any LED retrofit product which meets all the expectations of consumers in terms of price, light output and other functionalities at the same time.

The Consumerizing Solid State Lighting (CSSL) project aims to develop and demonstrate affordable Smart Solid State Light sources for consumers via both technology and application routes. The proposed CSSL project works vertically across the entire value chain from LED die, light source, consumer luminaires, controls and dimmer companies aiming to achieve substantial cost reduction. The CSSL project will also work with the energy companies to both gain valuable end user insights and explore new business model that would further promote and develop the consumer LED retrofit market.

 

 

In order to achieve drastic cost reduction on system level, the CSSL project will investigate the technology to grow GaN epilayers for LED purpose on large size silicon wafers, which has the potential to ultimately cut the cost of packaged LED die by half. An inline inspection tool will also be developed which when used in combination with a defect source analysis (DSA) tool will help to improve the LED yield during the semiconductor manufacturing process. In addition, the MCLED architecture, chip configuration and driver topology will be extensively studied and optimised to enable the lowest overall system cost option, namely, system-in-package. Finally, as LED light sources are digital, light sources, implementation of Digital Smart Lighting concept via integration of sensors, actuators and controls for dimmability and controllability, will utilize the full potential of the digital source and offer more functions to the consumer, which could be perceived as additional features when compared with the traditional light sources.

 

Multiple LED retrofit lamp, luminaries and system level demonstrators will be delivered during the project execution to show the research and development achievements. User perception tests and field tests of comparable LED retrofit products and demonstrators will also be carried out yearly in order to verify and optimise the overall LED retrofit system architecture.

 

The proposed CSSL project will have profound impact on many European industries such as microelectronics, dimmer and control, equipments and tools and material industry etc, and provide new business growth opportunities and promoting cross industry cooperation. The CSSL consortium will enable the consortium partners to secure a leading position in the emerging domain of consumer LED retrofit. The project will strengthen Europe’s position in the technology competition of spurring lighting manufacturers to  develop high quality, high-efficiency LED products to replace the ordinary light bulb. The results will have a direct impact on energy saving, sustainability and improve the quality of life in Europe and worldwide.
