Objective

The European lighting industry aims at reducing cost, at continuously improving product performance while reducing time to market and enlarging the product.
The main challenge for the design in of LED components into lighting systems is the temperature and current dependence of their performance.
In order to achieve a good design of LED systems, a modular, multi-physics based modelling approach is needed – this way allowing the freedom for LED component integrators to use such models in any kind of luminaire designs. In order to overcome those key challenges, seamless integration of the LED in the product development chain is necessary. For that a bridge, in the form of standardization, has to be established between the semiconductor industry and the LED component integrators.
In order to achieve this, the following tools have to be provided:
• Generic, multi-domain model of LED chips
• Compact thermal model of the LED chips’ environment
• Modeling interface towards the luminaire
The goal of the project is to develop a standardized method to create multi-domain LED compact models from testing data.
The objectives are:
• Define set of LED model equations that can be implemented into a FEM/CFD tool, for the purpose of self-consistent multi-domain simulation of LEDs thermal, electrical and light output characteristics.
• Provide interfacing between measurement tools, modelling tools and simulation tools to allow the application of the compact LED models.
• Prove the benefits of the use of compact models in the development process to reduce development times and cost.
This will lead to an industry standard in the lighting industry.
Achievement of this project is expected to boost time to market of LED products cut by 1/3, cut development cost by 50%, reduce Cost of Non-quality by 25%. The European lighting industry is offered a unique competitive advantage, necessary to catch the 30-40% speed of growth of its LED market and tape into potential new markets.

Periodic Reporting for period 1 - DELPHI4LED (From Measurements to Standardized Multi-Domain Compact Models of LEDs)

Reporting period: 2016-06-01 to 2017-05-31

Summary of the context and overall objectives of the project

Objectives
The goal of the project is to develop a standardized method to create multi-domain (thermal-electrical-optical) LED compact models from testing data.

The key objectives are:
• Define set of LED model equations that can be implemented into a FEM/CFD tool, for the purpose of self-consistent multi-domain simulation of LEDs thermal, electrical and light output characteristics.
• Provide interfacing between measurement tools, modelling tools and simulation tools to allow the application of the compact LED models.
• Prove the benefits of the use of compact models in the development process to reduce development times, cost and prepare for the digital revolution.

See Led characterization and Compact Model creation

Relevance and Impact
The European lighting industry faces a couple of key challenges due to the introduction of LED:
• On the market side, it is necessary to speed up development time, improve quality of current LED products and enable towards value-added activities in order to gain competitive advantage.
• On the development side, LED lighting has different challenges than conventional lighting applications. New characterisation procedures have to be defined as well as new standardization in order to boost LED adoption.
This will lead to an industry standard in the lighting industry.

Achievement of this project is expected to boost time to market of LED products cut by 1/3, cut development cost by 50%, reduce Cost of Non-quality by 25%.
The European lighting industry is offered a unique competitive advantage, necessary to catch the 30-40% speed of growth of its LED market and tape into potential new markets.
Delphi4LED provides first mover advantage to the European LED ecosystem in providing tools and methods for integration into Digital Manufacturing chain. Thus ensuring a long term competitive advantage.

Technical Innovation
In order to achieve a good design of LED systems, a modular, multi-domain based modelling approach is needed – this way allowing the freedom for LED component integrators to use such models in any kind of luminaire designs.
In order to overcome those key challenges, seamless integration of the LED in the product development chain is necessary. For that a communication bridge, in the form of standardization, has to be established between the semiconductor industry (LED
supplier) and the Lighting industry (LED component integrators).

In order to achieve this, the following tools have to be provided:
• Generic, multi-domain model of LED chips
• Compact thermal model of the LED chips’ environment
• Modeling interface towards the luminaire

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)
