Thermal design of an led system: A special lantern for Turkish historical mosques

In this study, LEDs are used to design a modern lantern for the interior lighting of Turkish historical mosques, aiming at achieving substantial energy savings and preserving the historical texture of the mosque at the same time. One of the most important methodologies in designing a lighting system with LEDs is the thermal design aspect. For the application of the system, the thermal design process of the modern mosque lantern is elaborated in detail; photometric measurements of selected LEDs are made, thermal simulations are carried out, the design approach is ameliorated according to the results of the simulations, a prototype is produced and verification measurements are performed. The resulting system provides a satisfactory thermal performance which translates into a long lifetime and sustainability. Thus, the study forms an important example of how an ancient system can be turned into an LED lighting system to be used in the lighting of a historical place of worship.
