New design tools bring large-area LED products on the market with speed, quality and lower costs
VTT Technical Research Centre of Finland develops novel LED light sources based on large, flexible and transparent substrates in collaboration with the Finnish companies Flexbright and Lighting Design Collective. An easy-to-customise LED foil suitable for mass production enables the introduction of the large area lighting and display technologies to applications such as vehicles, greenhouses, shopping centres and architectural lighting.
The three-year European project Delphi4LED develops design and simulation tools for LED structures to better meet the needs of the rapidly evolving lighting industry and end users.
Heat management is a key factor dictating the performance and reliability of LED lighting solutions. The operation of LED components is also affected by their electrical and optical characteristics. Combining all of these properties is difficult using the existing design tools.
In Delphi4LED project new simulation models are being developed to consider the above factors in a simplified form. This saves on computing capacity, enabling a more comprehensive design than is currently possible.
