Systems, components, and methods for electronic candles with moving flames
An electronic candle ( 10 ) which simulates a flickering flame is provided. The candle ( 10 ) includes a hollow shell ( 12 ), a light-emitting element ( 18 ) such as an LED and a cap member ( 20 ) having the contour of a burning flame covering the light-emitting element ( 18 ). An electromagnet is provided to swing the light-emitting element ( 18 ). The electromagnet is mounted on a bracket ( 26 ) and receives an alternating current. A holding member ( 40 ) has a dead weight ( 52 ) at one end and the light-emitting element ( 18 ) at the other end. A permanent magnet ( 54 ) is attached to the bottom of the dead weight ( 52 ) such that when an alternating current is applied to the electromagnet it creates a magnetic field for acting on the permanent magnet ( 54 ) causing the holding member ( 40 ) to swing along an axial direction of the bracket ( 26 ). The electromagnet, bracket, dead weight, holding member and permanent magnet are concealed inside the shell ( 12 ) with a neck ( 46 ) of the holding member ( 40 ) to which the light-emitting element is affixed extending out the top end ( 16 ) of the shell ( 12 ).
1. An electronic candle comprising:
a generally cylindrical shell having a hollow interior, a top end, a bottom end and a longitudinal axis;
a light-emitting element disposed at the top end of said shell;
a cap member having a contour resembling a flame of a burning candle, wherein the cap member covers the light-emitting element;
an electromagnet assembly disposed within the hollow interior of the shell adjacent the bottom of the shell, said electromagnet assembly being configured to operatively swing said light-emitting element in a pendulum manner transversely to the longitudinal axis of said shell;
a hollow bracket member mounted in the shell, the bracket member being provided with a pair of opposing openings below a top edge of the bracket member; and
a holding member mounted in the bracket member, the holding member comprising a pair of opposing swing arms extending outwardly from a lower part of the holding member, each swing arm engageable with a corresponding opening in the bracket member.
2. The electronic candle of claim 1 , comprising a screw base assembly disposed on the bottom end of the shell, said screw base assembly being configured to be engaged into a light bulb socket.
3. The electronic candle of claim 2 , further comprising an electronic circuitry means coupled to the screw base assembly for delivering electrical current to the light-emitting element and the electromagnet assembly.
4. The electronic candle of claim 1 , said bracket member having a first end, a second end, and a spool portion, said bracket member being positioned in the shell below the top end.
5. The electronic candle of claim 4 , wherein a coil of wire is wrapped around the spool portion of the bracket member proximate the first end of the bracket member.
6. The electronic candle of claim 5 , wherein the holding member has an upper part and wherein the light-emitting element is mounted in the upper part of said holding member.
7. The electronic candle of claim 6 , wherein a tubular neck portion extends between the upper part and the lower part of the holding member.
8. The electronic candle of claim 1 , wherein the light-emitting element comprises at least one light-emitting diode.
9. An electronic candle comprising:
a generally cylindrical shell having a hollow interior, a top end, a bottom end and a longitudinal axis;
a light-emitting element disposed at the top end of said shell;
a cap member having a contour resembling a flame of a burning candle, wherein the cap member covers the light-emitting element;
a holding member mounted in the shell and supporting the light emitting member, the holding member comprising a pair of opposing hollow co-axial swing arms extending outwardly from a lower part of the holding member;
an electromagnet assembly disposed within the hollow interior of the shell below the holding member, said electromagnet assembly being configured to operatively swing said light-emitting element in a pendulum manner transversely to the longitudinal axis of said shell; and
a hollow bracket member mounted in the shell in a surrounding relationship to the holding member, the bracket member being provided with a pair of opposing openings below a top edge of the bracket member, the openings being configured to pivotally engage a corresponding swing arm of the holding member.
10. The electronic candle of claim 9 , the bracket member having a first end, a second end, and a spool portion, said bracket member being positioned in the shell below the top end.
11. The electronic candle of claim 10 , wherein a coil of wire is wrapped around the spool portion of the bracket member proximate the first end of the bracket member.
12. The electronic candle of claim 9 , comprising a screw base assembly disposed on the bottom end of the shell, said screw base assembly being configured to be engaged into a light bulb socket.
13. The electronic candle of claim 12 , further comprising an electronic circuitry means coupled to the screw base assembly for delivering electrical current to the light-emitting element and the electromagnet assembly.
14. The electronic candle of claim 9 , wherein a bore is formed in the swing arms, and wherein a dowel is inserted into the bore, said dowel extending outwardly from the swing arms.
15. The electronic candle of claim 14 , wherein opposing ends of the dowel each have cap a member configured to fit into the opposing openings of the bracket member.
