Scavengers for reducing contaminants in liquid-filled LED bulbs

摘要

A liquid-cooled light emitting diode (LED) bulb which includes a base, a shell connected to the base forming an enclosed volume, and a plurality of LEDs attached to the base and disposed within the shell. The LED bulb also includes a volume of thermally-conductive liquid held within the enclosed volume. A scavenger element comprising a scavenger material is attached to the base and is exposed to the thermally-conductive liquid. The scavenger material is configured to capture contaminants in the thermally-conductive liquid.

1. A method of making a liquid-cooled light emitting diode (LED) bulb configured to capture contaminants, the method comprising:
attaching a shell to a base to form an enclosed volume; attaching a plurality of LEDs to the base, the plurality of LEDs disposed within the shell; completely filling the enclosed volume with a thermally-conductive liquid; and attaching a scavenger element to the base, the scavenger element comprising a scavenger material that is configured to capture contaminants in the thermally-conductive liquid, wherein the scavenger element is attached in a location that exposes the scavenger material to the thermally-conductive liquid.
