Abstract
An LED bulb has a base, a shell connected to the base, and a thermally conductive liquid held within the shell. The LED bulb has a plurality of LEDs mounted on LED mounting surfaces disposed within the shell. The LED mounting surfaces face different radial directions, and the LED mounting surfaces are configured to facilitate a passive convective flow of the thermally conductive liquid within the LED bulb to transfer heat from the LEDs to the shell when the LED bulb is oriented in at least three different orientations. In a first orientation, the shell is disposed vertically above the base. In a second orientation, the shell is disposed on the same horizontal plane as the base. In a third orientation, the shell is disposed vertically below the base.
