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 coupled to the candle body such that the flame-shaped piece configured to move in at least two dimensions;

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

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

wherein the flame-shaped piece comprises a lower portion having a hollow interior, and wherein a lower portion of a support member is configured to extend upwardly within the hollow interior of the portion; and

wherein the lower portion of the flame-shaped piece comprises a cone-shaped section coupled to a flame-shaped section, and wherein the hollow interior is at least partially defined by the cone-shaped section.

2. The device of claim 1, wherein the flame-shaped piece is coupled to the candle body such that the flame-shaped piece configured to move in three dimensions.

3. The device of claim 1, further comprising a magnet coupled to the cone-shaped section, and wherein the agitator comprises an electromagnet disposed to interact with the magnet.

4. The device of claim 3, wherein the electromagnet is disposed about the support member, such that the support member passes through the electromagnet, and wherein the electromagnet is configured to generate a magnetic field that interacts with the magnet.

5. The device of claim 1, wherein the cone-shaped section comprises an opening at a bottom and wherein the support member is configured to extend upwardly through the opening at the bottom.

6. The device of claim 1, wherein the 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. The device of claim 6, wherein the support member comprises a source of light at a first end of the support member, and wherein the first end is disposed near the aperture, such that light from the support member may illuminate the flame-shaped piece.

8. The device of claim 1, wherein a portion of the flame-shaped piece is clear such that at least some of the support member is viewable through the clear portion of the flame-shaped piece, and wherein the visible portion of the support member is configured to resemble a wick when viewed through the flame-shaped piece.

9. An electric lighting device, comprising:

a candle body;

a flame-shaped piece coupled to the candle body such that the flame-shaped piece configured to move in at least two dimensions, wherein the flame-shaped piece comprise a flame-shaped portion and 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 configured to extend through the support hole into the hollow interior portion of the flame-shaped piece, thereby suspending at least a portion of the flame-shaped piece within the candle body;

wherein the flame-shaped piece comprises a protrusion that extends from a perimeter of the support hole toward a center of the support hole; and

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

10. The device of claim 9, wherein the protrusion extends upwardly toward the center of the support hole.

11. The device of claim 10, wherein the protrusion is parallel to an outer surface plane of the flame-shaped piece at the support hole.

12. The device of claim 10, wherein the support member comprises a cup portion at a first end, and wherein the first end is configured to extend through the support hole, and wherein the flame-shaped piece comprises a downwardly-extending projection configured to rest in the cup portion.

13. The device of claim 9, wherein the support member comprises a cup portion at a first end, and wherein the first end is configured to extend through the support hole, and wherein the flame-shaped piece comprises a downwardly-extending projection configured to rest in the cup portion.

14. The device of claim 9, wherein the flame-shaped piece is coupled to the support member such that the flame-shaped piece configured to move in three dimensions.

15. The device of claim 9, wherein the lower portion comprises a cone-shaped section that at least partially defines the hollow interior.

16. The device of claim 9, further comprising a magnet coupled to the flame-shaped, and wherein the agitator comprises an electromagnet disposed to interact with the magnet.

17. The device of claim 9, wherein the agitator comprises a fan disposed beneath the flame-shaped piece, such that air from the fan causes movement of the flame-shaped piece.

18. An electric lighting device, comprising:

a candle body having an inner housing;

a flame-shaped piece coupled to the inner housing via a support member that is insertable into a 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;

wherein the support member comprises a cup portion at a first end, and wherein the first end extends from the inner housing into a hollow interior of the flame-shaped piece, such that the cup portion is disposed within the flame-shaped piece in the hollow interior;

wherein the flame-shaped piece comprises a projection that extends downwardly within the hollow interior, and wherein the projection rests within the cup portion when the first end of the support member is inserted within the flame-shaped piece; and

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

19. The device of claim 18, wherein the flame-shaped piece is coupled to the support member such that the flame-shaped piece configured to move in three dimensions.

20. The device of claim 18, further comprising a magnet coupled to the flame-shaped, and wherein the agitator comprises an electromagnet disposed to interact with the magnet.
