LEDLUM aims to develop a highly integrated cost competitive light engine t echnology platform for Solid State Lighting (SSL) connected directly to the electrical power grid. For the first time LEDLUM proposes to develop an integrated system level solution for realising a highly miniaturised, efficient light engine. LEDLUM will strengthen Europe’s lighting business with advanced technology and is expected to create around 1,000 new highly educated Jobs.

Motivation:
The majority of SSL systems is using high brightness light emitting diodes (LED) as the light source. The light engine, being part of the lighting system contains
a LED module as well as a driver, which is usually rather bulky and expensive and suffer from short lifetime. Presently, the need for bully, expensive and discrete
power electronics circuits to drive the light engine is a bottleneck limiting their application space. LEDLUM proposes to address these bottlenecks in miniaturisation and integration for the different components of the driver electronics, including power switching technology, control, passive components and system Integration with the light engine. This innovative solution will significantly expand the scope and opportunity for smart and highly integrated light engines where size and increased functionalities are key requirements.

Concept:
LEDLUM will make major improvements to the volume, the weight, the lifetime and the size of the driver (electrical engine) of light emitting diodes (LED), that are used in the majority of solid state light (SSL) systems. These improvements will be made while keeping the power rating of the driver. To achieve this, the operating frequency of the driver will be increased by approximately a factor of 1,000.

Objectives:
The LEDLUM project aims to reach the following objectives:

• 90% size and weight reduction of the power electronics part in the LED driver,
• reduction of material cost by a factor of 2,
• reduction of energy losses by 45%, and
• increase of the expected lifetime from 5 to 10 years.
