AB - It is an effective way of energy conservation to use high power LED armature  in street lighting. However, there exists some restrictions in front of the  usage of that, like overheating of LED chips and high weight of armature  case. Generally, aluminum heat sinks are attached to housing of the armature  to get effective working of LED armature. In this study, a street type high  power LED armature has been modeled numerically, transient thermal system has  been analyzed and the results have been compared with experimental results in  order to decrease the armature weigh and increase efficiency. Also, in  experimental studies thermal camera and thermocouples have been used for  thermal measurements. Finally, multi-objective optimization has been  performed to decrease the armature weight, while keeping maximum temperature  on armature between in safely working interval.
