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 facilitate a flow of the thermally conductive liquid from the LED mount to an inner surface of the shell.
Claims21
A light-emitting diode (LED) bulb comprising:
- a shell;
- at least one LED mount disposed within the shell;
- at least one LED attached to the at least one LED mount;
- a thermally conductive liquid held within the shell, wherein the LED and LED mount are immersed in the thermally conductive liquid;
- and
- a liquid displacer immersed in the thermally conductive liquid, wherein 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, and wherein the liquid displacer is configured to facilitate a flow of the thermally conductive liquid from the LED mount to an inner surface of the shell.
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 LED mount are immersed in the thermally conductive liquid;
- and
- a liquid displacer immersed in the thermally conductive liquid, wherein 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.
(canceled)
A method of making a light-emitting diode (LED) bulb having one or more LEDs, comprising:
- placing a first locator ring with a shell of the LED bulb;
- attaching displacer segments to the first locator ring;
- attaching a second locator ring to the displacer segments, wherein the second locator ring is larger than the first locator ring, wherein the first locator ring, the displacer segments, and the second locator ring form a liquid displacer within the shell;
- filling the shell with a thermally conductive liquid, wherein 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.
