Abstract

An LED bulb includes at least one LED mount disposed within a shell. At least one LED is attached to the at least one LED mount. A thermally conductive liquid is held within the shell. The LED and LED mount are immersed in the thermally conductive liquid. A liquid displacer is immersed in the thermally conductive liquid. The liquid displacer is configured to displace a predetermined amount of the thermally conductive liquid to reduce the amount of thermally conductive liquid held within the shell. The liquid displacer is also configured to be compressible, where the liquid displacer is compressed in response to expansion of the thermally conductive liquid.
