Abstract

Various components for artificial candles and other lighting devices are described that can be used to create a realistic flame effect in the devices. The devices include a flame piece or element that extends upwardly from a body of the device. A light source can be disposed with respect to the flame piece such that the flame piece is illuminated. A variety of drive mechanisms could be disposed within the body of the device that can cause movement of the flame piece with respect to the body or housing. The flame piece can be coupled to a body or housing of the device using various components to suspend at least a portion of the flame piece within the body or housing.

Claims

1. An electric lighting device, comprising:

a candle body;

a flame-shaped piece at least partially disposed within the candle body;

a light source disposed within the candle body such that light is emitted on the flame-shaped piece;

an agitator configured to cause movement of the flame-shaped piece with respect to the candle body;

wherein the flame-shaped piece comprises a hollow interior portion, and wherein a first end of a support member is configured to extend into and upwardly within the hollow interior portion, such that when the flame-shaped piece is placed on the first end, the flame-shaped piece may move with respect to the candle body; and

wherein the weight of the flame-shaped piece is distributed such that a center of mass of the flame-shaped piece is located below a point where a tip of the support member interacts with the interior of the flame-shaped piece.

2. The device of claim 1, wherein the agitator comprises a fan disposed below the flame-shaped piece, such that air is directed toward the flame-shaped piece.

3. The device of claim 1, wherein the flame-shaped piece comprises a magnet disposed at or near a bottom of the flame-shaped piece, and wherein the agitator comprises an electromagnet disposed within the candle body and configured to generate an electromagnetic field, and wherein interaction of the magnet with the electromagnetic field causes movement of the flame-shaped piece.

4. The device of claim 1, wherein the flame-shaped piece comprises a cone shaped bottom piece that defines the hollow interior.

5. The device of claim 4, wherein the cone-shaped bottom piece comprises an opening at a lower portion and wherein the support member is configured to extend upwardly through the opening at the lower portion.

6. The device of claim 1, wherein a lower portion of the flame-shaped piece having the hollow interior comprises a cone-shaped section coupled to a flame-shaped section, and wherein the flame-shaped piece comprises an aperture that extends from an outer surface of the flame-shaped piece to the hollow interior.

7. An electric lighting device, comprising:

a candle body comprising an interior portion;

a flame-shaped piece at least partially disposed within the interior portion, wherein the flame-shaped piece comprise a flame-shaped top portion and a bottom portion having a hollow interior;

a light source disposed on or within the candle body such that light is emitted on the flame-shaped piece;

a support member configured to extend into the hollow interior of the bottom portion to support the flame-shaped piece and permit movement of the flame-shaped piece; and

an agitator configured to cause movement of the flame-shaped piece with respect to the candle body.

8. The device of claim 7, wherein the support member comprises a protrusion that extends upwardly within the hollow interior of the bottom portion when the support member is inserted into the flame-shaped piece.

9. The device of claim 7, wherein the support member comprises a cup portion at a first end, and wherein the flame-shaped piece comprises a downwardly-extending projection configured to rest in the cup portion such that the flame-shaped piece is supported by the support member.

10. The device of claim 7, wherein the bottom portion comprises a cone-shaped section that at least partially defines the hollow interior.

11. The device of claim 7, wherein the bottom portion includes a magnet, and wherein the agitator comprises an electromagnet configured to generate a magnetic field that interacts with the magnet and causes movement of the flame-shaped piece.

12. An electric lighting device, comprising:

a candle body having an interior portion;

a flame-shaped piece at least partially disposed within the interior portion such that the flame-shaped piece is configured to move in at least two dimensions, wherein the flame-shaped piece comprises (a) a flame-shaped upper portion and (b) a lower portion having a hollow interior, and wherein the flame-shaped piece further comprises a support hole on one side of the flame-shaped piece;

a light source disposed with respect to the candle body such that light is emitted on the flame-shaped piece;

a support member having a first end configured to extend through the support hole into the hollow interior portion of the flame-shaped piece, and on which the flame-shaped piece rests; and

an agitator configured to cause movement of the flame-shaped piece with respect to the support member.

13. The electric lighting device of claim 12, wherein the flame-shaped piece comprises a protrusion that extends from a perimeter of the support hole toward a center of the support hole.

14. The electric lighting device of claim 13, wherein the protrusion extends upwardly toward the center of the support hole.

15. The electric lighting device of claim 13, wherein the protrusion is parallel to an outer surface plane of the flame-shaped piece at the support hole.

16. The electric lighting device of claim 12, wherein the support member comprises a projection at the first end.

17. The electric lighting device of claim 12, wherein the support member comprises a cup portion at the first end, and wherein the flame-shaped piece comprises a downwardly-extending projection configured to rest in the cup portion.

18. The electric lighting device of claim 12, wherein the lower portion includes a magnet, and wherein the agitator comprises an electromagnet configured to generate a magnetic field that interacts with the magnet and causes movement of the flame-shaped piece.

19. The electric lighting device of claim 12, wherein the agitator comprises a fan disposed beneath the flame-shaped piece, such that air from the fan is directed toward the flame-shaped piece to cause movement of the flame-shaped piece.

20. The electric lighting device of claim 12, wherein the lower portion comprises a cone-shaped section that at least partially defines the interior portion.
