A white paper showing how the FLS1000 Photoluminescence Spectrometer is used to investigate the emission properties of a phosphor coated indium gallium nitride white light LED using both steady state and time-resolved electroluminescence spectroscopy.
MKS Instruments’ new Ophir FluxGage FG1500 measurement system for LED luminaires enables the photometric measurement of large-size street and industrial luminaires, LED flat panels, and troffer lights
In 1907 English engineer Henry Joseph Round was testing the rectifying current behaviour of SiC crystallites and noticed that a faint yellow light was emitted from the SiC; this was simultaneously the first reported observation of the phenomena of electroluminescence spectroscopy and the first successful operation of a light emitting diode (LED). The work of Round was expanded on by a few others in the early 20th century, but it would take many decades for LEDs to become efficient enough for practical use.
LpS is Europe’s leading international lighting technologies conference and exhibition for design, testing and production of lighting systems, controls and equipment. Now in its 8th year, LpS brings you the greatest minds in lighting together to tackle this year’s key topics of humanising technology, the transformation to the connected world and creative approaches to adapt to the disruption of the lighting industry.
