Abstract
An LED lamp has an envelope that includes a globe and a case, an interior space of the envelope being divided in two by a mount closing an opening of the globe, the lamp containing, in a globe side of the interior space, an LED and, in a case side of the interior space, a circuit unit for causing the LED to emit light. The LED is thermally connected to the mount, and the mount and the case are joined to the globe such that, during light emission, at least as much heat from the LED is propagated from the mount to the globe as from the mount to the case.
