Abstract:
A liquid-filled light emitting diode (LED) bulb including a base, a shell connected to the base forming an enclosed volume, a thermally conductive liquid held within the enclosed volume, a support structure connected to the base, and several LEDs attached to the support structure. The thermally conductive liquid has an oxygen content of at least 5 cubic centimeters of oxygen per liter of the thermally conductive fluid.
