Abstract
An LED bulb includes a shell, one or more LEDs, a thermally conductive liquid, and a liquid-volume compensator mechanism. The one or more LEDs are disposed within the shell. The thermally conductive liquid is held within the shell. The liquid-volume compensator mechanism is configured to compensate for expansion of the thermally conductive liquid.
