Abstract
An LED bulb includes a base, a shell connected to the base, an LED mount disposed within the shell, one or more LEDs, a thermally conductive liquid, and a liquid-volume compensator mechanism. The one or more LEDs are mounted on the LED mount. The thermally conductive liquid is held within the shell. The liquid-volume compensator mechanism moves from a first position to a second position to compensate for expansion of the thermally conductive liquid.
