According to a recent study, many solid-state lighting (SSL) products do not fulfill the claimed specifications and a deep market penetration of LED modules is at risk. The main problems are decreasing light intensity and varying light chromaticity due to aging and temperature, as well as poor uniformity of large-area luminaires and poor lighting quality. The main objective of the LASSIE-FP7 conso ...

The lighting industry worldwide faces a paradigm shift as a new era of lighting appears at the horizon: that is Solid State Lighting (SSL). Light emitting diodes (LEDs) based on inorganic semiconductors are mercury-free, have a long lifetime and instant on/off, can be colour tunable and most important: they will become the light source with the highest energy-efficiency in the near future. Thus, L ...
