Design and Thermal Analysis of High Power LED Light

In the development of lighting technologies, light emitting diode (LED) technology plays an important role due to its high efficiency. LED lightening is future indoor and outdoor illumination solutions that all around world there a widespread transition save energy have better quality via LED-based solutions. On other hand, cooling power crucial factor utilize in performance. addition, finned heat sink could not be efficient based on geometry usage areas powder, rain muds effects. this study, un-finned armature consisting aluminum sheet metal was designed using computer-aided-design (CAD) program. Furthermore, manufacturing sinks from plates with bending machines enables increase variety armatures cheaply according design requirements. Then, thermal analysis system conducted for case natural convection under different electrical powers ambient temperatures by commercial finite element (FEA) program: SolidWorks Simulation. As result analysis, ultimate sizes were obtained minimize junction temperature LED. Finally, experimental studies carried out verify feasibility numerical they good agreement.
