Abstract:
1. A light-emitting diode (LED) bulb comprising: a shell; one or more LEDs disposed within the shell; a thermally conductive liquid held within the shell, wherein at least a portion of the thermally conductive liquid is in contact with the shell; a central protrusion disposed within a central portion of the shell; and a liquid-volume compensator mechanism disposed, at least partially, within the central protrusion, wherein the central protrusion includes an opening configured to fluidically connect the liquid-volume compensator mechanism to the thermally conductive liquid, and wherein the liquid-volume compensator mechanism is configured to compensate for expansion of the thermally conductive liquid.
