  • Patent number: 5504664
    Abstract: Illuminated jewelry connectable to a wearer as an earring, a clothes pendant or the like includes a light-emitting diode (LED) connected onto an enlarged flat base member at one end of an elongated stem. A miniature battery housing also includes a stem cavity positioned immediately adjacent and generally coextensive with the battery compartment to supportively receive and closely mate with the distal portion of the stem therewithin through the use of an intermediate semi-rigid plastic tube secured within the stem cavity. The intermediate tube frictionally acts upon the stem to hold the stem at any desired depth into the tube. The stem and housing are structured so that an electrical circuit is completed between the battery and the LED through the stem when the stem is fully inserted to the bottom of the stem cavity. In this configuration, a gap between the enlarged base member and the housing generally equal to the thickness of the wearer's earlobe or article of clothing is defined.

A miniature battery housing also includes a stem cavity positioned immediately adjacent and generally coextensive with the battery compartment to supportively receive and releasably retain the distal portion of the stem therewithin.

In this configuration, a gap between the enlarged base member and the housing generally equal to the thickness of the wearer's earlobe or article of clothing is defined. A transparent lens over the LED may be provided to enhance decorative illumination.
