  • Patent number: 5018053
    Abstract: The present invention discloses illuminated jewelry which is adapted for use as an earring, lapel pin broach, tie clip, cuff link, etc. A light source, such as an LED, is molded with a non-conducting, light transmissive material, which is preferably faceted to provide multiple reflected images of the illuminated light source. A power source, such as a small battery, is held by a retainer which provides electrical contact with one terminal of the power source. A lead finding is pivotally secured to the retainer at one end, and is secured at the opposite end to the light source. A lead post is secured to the light source, and positioned to contact the opposite terminal of the power source to energize the light source when the retainer is moved to a closed position. When the retainer is moved to an open position, the circuit between the power supply and the light source is broken. A biasing means is disposed between the retainer and the lead finding, to urge the illuminated jewelry open and closed positions.
