Abstract

An electronic lighting device and a method for manufacturing the same are disclosed. The electronic lighting device may comprise a core, which may comprises an enclosure, a light-emitting element, a flame sheet and a swing mechanism. The flame sheet is movably supported or suspended on the enclosure, and may comprise an upper sheet which is of a flame-like shape. The upper sheet is configured to expose above the top of the enclosure. The light-emitting element may be installed on the enclosure. A light outgoing direction of the light-emitting element may be intersected with the surface of the upper sheet so that the light of the light-emitting element is projected on the surface of the upper sheet. The swing mechanism is disposed beneath the flame sheet and can apply a force on the flame sheet to actuate the flame sheet to sway or swing. By the present application, a visual experience of true fire can be achieved and an interestedness and appreciation can be improved.

First claim

What is claimed is:

1. A flame element for use in an imitation candle device, comprising:
a flame sheet including an upper portion and a lower portion, the upper portion of the flame sheet shaped to resemble a fire flame;
a hanging member, wherein a first end of the hanging member is coupled to the lower portion of the flame sheet; and
a swing piece coupled to a second end of the hanging member to allow the swing piece to hang downward under a force of gravity.

2. The flame element of claim 1 , wherein the hanging member comprises a rope that is attached to a lower end of the lower portion of the flame sheet.

3. The flame element of claim 1 , wherein the upper portion of the flame sheet includes one or more depressions.

4. The flame element of claim 2 , wherein the upper portion of the flame sheet includes one or more depressions.

5. The flame element of claim 1 , wherein the lower portion of the flame sheet has a lower end that is substantially rectangular in shape.

6. The flame element of claim 1 , wherein flame sheet includes a middle portion that includes a through hole for insertion of a support rod upon which the flame sheet sways.

7. The flame element of claim 1 , wherein the upper portion of the flame sheet is curved to form a non-zero angle with respect to a vertical axis that runs through the flame sheet.

8. The flame element of claim 7 , wherein the lower portion of the flame sheet has a lower end that is substantially rectangular in shape.

9. An imitation candle device, comprising:
a housing;
a flame element that includes:
(a) a flame sheet including an upper portion and a lower portion, the upper portion of the flame sheet shaped to resemble a fire flame;
(b) a hanging member, wherein a first end of the hanging member is coupled to the lower portion of the flame sheet; and
(c) a swing piece coupled to a second end of the hanging member to allow the swing piece to hang downward under a force of gravity;
a rotary block coupled to an electrical motor and rotatable under control of the electric motor, the rotary motor positioned in the housing to contact the swing piece; and
one or more light sources to illuminate the upper portion of the flame element.

10. The imitation candle device of claim 9 , further including a support element passing through a through hole in a middle portion of the flame sheet and connecting at both ends to the housing.

11. The imitation candle device of claim 9 , wherein at least one of the one or more light sources is positioned on a sidewall of the housing to project light onto the upper portion of the flame sheet from within the housing.

12. The imitation candle device of claim 11 , wherein the housing includes a through hole on a top section of the housing, and wherein the at least one of the one or more light sources is positioned to illuminate the upper portion of the flame sheet through the through hole.

13. The imitation candle device of claim 9 , wherein the hanging member comprises a rope that is attached to a lower end of the lower portion of the flame sheet.

14. The imitation candle device of claim 9 , wherein the upper portion of the flame sheet includes one or more depressions.

15. The imitation candle device of claim 13 , wherein the upper portion of the flame sheet includes one or more depressions.

16. The imitation candle device of claim 9 , wherein the lower portion of the flame sheet has a lower end that is substantially rectangular in shape.

17. The imitation candle device of claim 9 , wherein in the upper portion of the flame sheet is curved to form a non-zero angle with respect to a vertical axis that runs through the flame sheet.

18. The imitation candle device of claim 17 , wherein the lower portion of the flame sheet has a lower end that is substantially rectangular in shape.

19. The imitation candle device of claim 9 , wherein the rotary block is positioned within the housing to collide with the swing piece upon actuation of the electric motor.

20. The imitation candle device of claim 9 , further including an electronic circuit having a microprocessor to control operation of the electric motor.
