Abstract: The present invention relates to LED assemblies used to replace bulbs in streetlights or similar illumination sources. The LED assemblies are self contained and comprise modules for the function and control of the LED assembly. The LED assembly can include additional capability for sensors and for communication external to the LED assembly. The LED assembly can include advanced features that can be remotely activated. The LED assembly fits within the same volume as the bulb it is replacing and therefore does not require the removal or addition of other hardware during the replacement of the bulb with the LED assembly.
