Abstract:
Reducing the consumption of electricity is one of the principal areas of current research into energy saving technologies. Within this area is the effort to reduce the demand for electricity for lighting purposes. To consider just the domestic requirements, during 2011 domestic electricity consumption in the UK was 30% of a total electricity demand of 374TWh. Of this figure of 112TWh some 13TWh were used for lighting alone. This thesis describes research made in this area, in particular the manufacture of lighting luminaires making use of High Brightness Light Emitting Diodes (HBLEDs). The thesis outlines and demonstrates a methodology for the design, testing and subsequent manufacture of complete luminaires which make suitable, low energy consumption alternatives to conventional lighting using filament lamps and fluorescent fittings. Work has been done in the areas of:Thermal management, Power supply design, Luminaire design, Performance simulation in software, 'Remote phosphor’ luminaires in which LEDs with blue light outputs are used to provide blue light which is converted to usable white light by phosphor laden acrylic plates employed in luminaires for both wavelength conversion and light diffusion, Luminaire performance measurementIt is shown that substantial savings in energy (over 50%) can be made by using HBLEDs in lighting luminaires whilst producing satisfactory lighting for a variety of purposes.
