Abstract

Light emitting electronic jewelry, an earring for example, includes an earring post having a light emitting diode supported thereon. The diode is connected in an electrical circuit including a battery means. In one form of the invention, the electrical circuit includes an integrated circuit and a capacitor electrically connected between the integrated circuit and light emitting diode such that the diode is caused to flash on and off. In another form of the invention, the electrical circuit includes a mercury switch electrically connected between the diode and battery so as to make and break the electrical connection therebetween in response to movements of the wearer. The battery and electrical circuit components may be supported within a casing suspended from the earring post.

Claims

1. A light emitting electronic earring comprising,

an earring post adapted for securement to a wearer'"'"'s earlobe,

a light emitting diode operatively supported on said post,

a battery means, and

an electrical circuit,

said light emitting diode and battery means being electrically connected in said circuit such that said light emitting diode is illuminated at times by said battery means,

said electrical circuit comprising a mercury switch electrically connected between said light emitting diode and battery means so as to make and break the electrical connection therebetween in response to movements of the wearer'"'"'s earlobe,

a casing,

said battery means and mercury switch being supported in said casing,

said electrical circuit including elongated conductor chains electrically connecting said light emitting diode to said mercury switch, said casing being suspended from said post by said conductor chains.

2. The earring of claim 1 further comprising a clasp removably engageable on said post, one of said conductor chains being discontinuous and having a first portion electrically connected to said post and a second portion electrically connected to said clasp whereby said post and clasp are operative as an on-off switch for said light emitting diode.

3. The earring of claim 1 wherein said first contact and said other contact are arranged in closely spaced relation as a pair of contacts and further comprising a plurality of said pairs of contacts disposed in spaced apart relation about the periphery of said insulator.

4. The earring of claim 1 wherein said quantity of liquid mercury is disposed in clearance relation from said contacts when said surface is horizontally disposed, thereby effecting a normally off condition for said mercury switch.

5. The earring of claim 1 wherein said earring post is of the pierced earring type and has interior and exterior ends, said light emitting diode being supported on said exterior end.

6. The earring of claim 1 wherein said mercury switch comprises a support surface within said casing, a first contact electrically connected to one of said battery means and said light emitting diode and disposed adjacent said support surface, at least one other contact electrically connected to the other of said battery means and light emitting diode and disposed adjacent said support surface, and a quantity of liquid mercury supported on said surface within said casing for electrically connecting said contacts when support surface is inclined toward said contacts.
