Abstract
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.
