French R&D program to test LED lighting for indoor illumination
The CITADEL program will develop measurement protocols and benchmarking analyses of LEDs, and methods to assess the aging and life expectancy of LED lighting products.
The program’s goal is to fully characterize LED lighting products, as they apply to the specific needs of buildings and tenants. The program hopes to define new measures of visual comfort and color rendering specific to LEDs, said Christophe Martinsons, head of the Lighting, Electricity and Electromagnetism Division of the CSTB.
The three-year project (started Feb. 9) has a budget of 1.5 M Euro and is funded by the French Environmental Agency (ADEME). The project was partly inspired by the US DoE CALIPER initiative.
“Like its American counterpart, CITADEL is intended to provide physical measurement protocols and benchmarking analyses. However, the scope of the CITADEL program goes beyond,” said Martinsons.
The program will determine aging methods (climatic and endurance) to assess the real-life expectancy of LED lighting products. Durability will be studied together with life-cycle analyses and total cost-of-ownership.
Lab measurements will be carried out using several types of metrology, microanalysis and aging setups. The project also includes numerical simulations, focus groups, economic calculations, as well as a complete environmental analysis.
The program’s consortium consists of the CSTB; CEA-LETI; LNE (the equivalent of NIST in the US); the Engineering School in Construction and Public Works; LAPLACE, a large electrical engineering lab(University of Toulouse and CNRS); and Philips Lighting.
The CITADEL is part of the innovation program of the “Cluster Lumière,” the French lighting cluster based in Lyon.
