Liquid-cooled led lamp

Abstract

An electrical device, preferably a light bulb having an electrical base, comprises a container having a sealed interior, an electrical component contained within the sealed interior; a liquid filling the sealed interior; and a pressure relief member. The pressure relief member has an interior tubular passage. The tubular passage has an inlet which is in fluid communication with the liquid. The tubular passage is filled with liquid from the inlet partially toward an outer end of the passage. The remainder of the passage is filled with gas. The pressure relief member provides relief from increases of pressure caused by heating the liquid. Preferably, a heat sink is provided for the electrical component and contacts the liquid coolant. The pressure relief member may be located either in the sealed interior or outside of the container.
