    A fluorescent fibre solar concentrator (FFSC) design and trial run / Wang Chen

    A fluorescent fibre solar concentrator (FFSC) design and trial run / Wang Chen by Wang, Chen

    Published 2009
    “…The wavelength test and the CIE color analysis present a satisfactory match in color between the FFSC light output an the natural light.Since the sun light is free, even though the luminous efficacy as 0.6431m/W is lower than the normal electrical light sources, FFSC does not consume any electricity when operating. …”

    An efficient self-configurable driver for color light emitting diode

    An efficient self-configurable driver for color light emitting diode by Shaheer Shaida, Durrani

    Published 2021
    “…It can be seen, the previous techniques had improved the luminous efficacy of LEDs by using n-level driving techniques but at the trade-off of losing efficiency with the introduction of resistors (variables in series) to create a bi-level phenomenon for the driver. …”
