This dissertation discusses the introduction of LED lighting in urban spaces as an example of innovative public … producers and users, but also urban observers. A series of six ethnographic case studies demonstrate how LED lighting was …

model of the LED lighting system was first derived. A 96W high-power LED luminaire was designed and built in the present … LED lighting system is of a multiple-input–multiple-output (MIMO) system with two inputs (applied voltage and ambient …

Light-emitting diode (LED) lighting offers greater energy efficiency than conventional lighting. However, if the heat … sink of LED lighting was optimized with respect to its fin-height profile to obtain reliable cooling performance for high …-power LED lighting applications. Natural convection and radiation heat transfer were taken into consideration and an experiment …

LED lighting has the potential to provide energy savings, and in many countries, there are policies to encourage its … light electric power in LED lights is still generated as heat, the sole use of LED lighting in a building could have a … negative effect on the cooling load. In this paper, we study the heating properties of LED lighting and establish a management …
