Lighting Emitted Diodes (LEDs) are currently being used in advanced lighting designs, mainly in the leisure industry, due to the technological advantages that they offer. Nevertheless, there have been key problems related to the adoption of LEDs in contemporary lighting design schemes. These include the photometry and colorimetry of LEDs, the limited available standards against which to compare and evaluate LEDs, the inadequacy of uniform definitions, and also the lack or inconsistency of data in the LED supply chain. In light of the above, the thesis aims at examining the implications of using LEDs in the illumination of the leisure industry, given the latest technological advancements. To achieve this goal, the thesis defines the Supply Chain of the LED industry. It discusses the flow of information between LED manufacturers, LED module manufacturers, luminaire manufacturers, lighting designers and end users. It analyzes the kind of information that each of these groups expects and receives from the other groups of the Supply Chain, for different kinds of LED applications. The thesis also discusses the importance of data availability to meet different lighting parameters in LED applications. Finally, the thesis notes the necessity for standards that ensure quality, reliable and comparable data. And it also provides guidelines on various issues that need to be taken into account when designing with LEDs. The thesis adds value to the lighting community by addressing issues not covered by previous research. In fact, it puts the whole “puzzle” of the LED lighting industry together by analyzing its different “pieces”: the market of lighting products, lighting design, standards availability, and end user requirements in the leisure industry. The originality of this research is related to the fact that it discloses the flow of information within the lighting industry and the way that the available knowledge is handled and distributed. The novelty of the thesis is also related to the fact that it reveals how information and data availability influence the adoption of LED technology and the decision making in regard to LED products for different kinds of applications. Through that, the thesis contributes to the lighting community by setting the importance of ‘quality’ lighting parameters when designing with LEDs, and by developing guidelines on how to handle the very fast changing technology of LEDs.
