Patent ID: 8686623

Claim:
A light emitting diode (LED) bulb comprising: a base; a shell connected to the base; a thermally conductive liquid held within the shell; a plurality of LEDs; and a plurality of LED mounting surfaces disposed within the shell, wherein each LED is mounted to one of the LED mounting surfaces, wherein the LED mounting surfaces face different radial directions, and wherein 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, the at least three different orientations comprising: a first orientation in which the shell is disposed vertically above the base; a second orientation in which the shell is disposed on the same horizontal plane as the base; and a third orientation in which the shell is disposed vertically below the base; wherein the LED mounting surfaces are portions of LED mounts, and wherein the LED mounts are finger-shaped projections, wherein the finger-shaped projections project into the thermally conductive liquid held within the shell.
