Sustainable Lighting – The Case for LEDs
LED lighting, (or solid state lighting) is a rapidly expanding market for niche lighting applications,
and is now making inroads into the general lighting market. Yet LED lighting is being faced with the very same consumer criticisms that plagued the introduction of CFL’s, that of poor light quality and high initial costs.
If LED lighting is to become the standard in lighting, these criticisms must be addressed, along with other issues such as power quality, and compatibility with existing light fittings in order to offer superior artificial lighting both in aesthetics and energy efficiency.
In this paper, the potential energy demand reduction that could be attained with more efficient lighting
practices is described. Following that a brief look at the qualities of LED lighting is discussed, and finally, the prospects of LED lighting in the future are assessed.
