EXPANDABLE LIQUID VOLUME IN AN LED BULB

摘要

An LED bulb includes a base, a shell, a plurality of LEDs, a thermally conductive liquid, and a liquid- volume compensator mechanism. The thermally conductive liquid is held within the shell. The plurality of LEDs is disposed within the shell, and immersed in the thermally conductive liquid. The liquid-volume compensator mechanism is disposed within the LED bulb. The liquid-volume compensator mechanism is configured to compensate for expansion of the thermally conductive liquid. The liquid-volume compensator mechanism moves from a first position to a second position. A first volume is provided for the thermally conductive liquid in the first position. A second volume, which is greater than the first volume, is provided for the thermally conductive liquid in the second position.
