Abstract
A light emitting diode (LED) bulb has a shell. An LED is within the shell. The LED is electrically connected to a driver circuit, which is electrically connected to a base of the LED bulb. The LED bulb also has a heatsink between the shell and base. A thermal break partitions the heatsink into an upper partition adjacent the shell and a lower partition adjacent the base.
