Metrology for efficient and safe innovative lighting

Short Name: MESaIL, Project Number: ENG62

Innovative lighting: New measurements for solid state lighting

Solid-state lighting (SSL) refers to a type of lighting that uses semiconductor light-emitting diodes (LEDs) as sources of illumination rather than electrical filaments, plasma (used in arc lamps such as fluorescent lamps), or gas. The second generation of SSL products is now being developed and includes organic light-emitting diodes (OLEDs), polymer light-emitting diodes (PLED) and nano-structured and flexible LEDs. They have the potential to revolutionise the efficiency, appearance and quality of lighting. This project developed measurement solutions and an advanced metrological framework for novel second generation SSL products, covering light output and efficiency, as well as safety and lifetime aspects. A new set of metrics were developed through physiological studies to investigate safety and comfort aspects of lighting and user perception. This will enable the reliable measurement of SSL performance and encourage the use of these forms of lighting and improve energy efficiency, reduce energy bills and enable consumers to make informed decisions regarding lighting products.
