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 plurality of beads is suspended in the thermally conductive liquid. The plurality of beads is configured to displace a predetermined amount of the thermally conductive liquid to reduce the amount of thermally conductive liquid held within the shell.
Claims20
A light-emitting-diode (LED) bulb comprising:
- a base;
- a shell connected to the base;
- at least one LED mount disposed within the base;
- at least one LED attached to the at least one LED mount;
- a thermally conductive liquid held within the shell, wherein the LED and the LED mount are immersed in the thermally conductive liquid;
- and
- a plurality of beads suspended in the thermally conductive liquid, wherein the plurality of beads is configured to displace a predetermined amount of the thermally conductive liquid to reduce the amount of thermally conductive liquid held within the shell, and wherein the plurality of beads is transparent or translucent.
