Electric lighting device
Electric lighting devices are described having a candle body with an upper surface coupled to a sidewall. A flame element is disposed entirely outside of the candle body and include one or more magnets or a ferrous material. The flame element is supported above the upper surface by a support member that extends upwardly from the upper surface and terminates at a first end disposed within the flame element. This allows the flame element some degree of movement about the support member that combined with a light source configured to illuminate a surface of the flame element creates a flickering flame effect. The device can also include a drive mechanism such as an electromagnet that generates an electromagnetic field that interacts with the magnets of the flame element to thereby cause movement of the flame element.
1. An electric lighting device, comprising:
a candle body having sidewalls, and an upper surface coupled to the sidewalls, defining an inner cavity of the candle body inside the sidewalls;
a support member extending upwardly from the upper surface and terminating at a first end;
a flame shaped element disposed outside of the candle body, supported by the support member, said flame shaped element having a bottom portion with a support surface adapted to press against said first end of said support member;
a first magnetic-attractable material on a first side of a bottom portion of the flame shaped element;
a second magnetic-attractable material on a second side of a bottom portion of the flame shaped element;
where the first material and the second material are on opposite ends of the bottom of the flame shaped element symmetrically disposed relative to one another,
wherein the support surface of the flame shaped element pivots on the first end of the support member; and
an electromagnet configured to generate an electromagnetic field that interacts with the first and second materials of the flame element to thereby cause the flame shaped element to pivot.
2. The electric lighting device of claim 1 , wherein the electromagnet is disposed within the candle body and beneath the upper surface.
3. The electric lighting device of claim 1 , wherein the electromagnet is has a first part closer to the first material and has a second part closer to the second material.
4. The electric lighting device of claim 1 , wherein the electromagnet concentrically surrounds the bottom portion of the flame shaped element.
5. The electric lighting device of claim 1 , further comprising a light source positioned to produce light on to the flame element.
6. The electric lighting device of claim 5 , wherein the light source is disposed entirely within the candle body and emits said light via an aperture in the upper surface.
7. The electric lighting device of claim 1 , wherein the flame element has inner surfaces defining a hollow interior portion between the first side of the bottom portion of the flame shaped element and the second side of the bottom portion of the flame shaped element, and between the first and second material.
8. The electric lighting device of claim 7 , wherein the first end of the support member has a recess, and the flame element has a projection, inside the hollow interior portion, that extends downwardly, and wherein the projection is configured to rest on the recess.
9. The electric lighting device of claim 1 , further comprising a retaining structure that retains the flame element relative to the support member, while allowing the flame element to pivot relative to the support member.
10. The electric lighting device as in claim 9 , wherein the retaining structure includes a flexible extension, attached to the support, that presses against inner surfaces of the flame element to hold the inner surfaces of the flame element from coming off of the support.
11. The electric lighting device as in claim 9 , wherein the retaining structure includes an insert that is inserted into the inner surfaces of the flame element after the flame element is inserted onto the support.
12. The electric lighting device of claim 5 , wherein the light source is disposed entirely within the candle body and emits said light via a light pipe configured to direct light from the light source through the support member.
13. An electric lighting device, comprising:
a candle body having sidewalls, and an upper surface coupled to the sidewalls, defining an inner cavity of the candle body inside the sidewalls;
a support member extending upwardly from the upper surface and terminating at a first end,
a flame shaped element disposed outside of the candle body, supported by the support member,
said flame shaped element having a bottom portion with a support surface adapted to press against said first end of said support member;
at least one magnetic-attractable material attached to the flame shaped element;
wherein the support surface of the flame shaped element pivots on the first end of the support member and the flame shape element is retained by a retaining structure against being removed completely from the first end of the support member; and
an electromagnet configured to generate an electromagnetic field that interacts with the at least one magnetic-attractable material to cause the flame shaped element to pivot.
14. The device as in claim 13 , wherein the at least one magnetic-attractable material includes a first magnetic-attractable material on a first side of a bottom portion of the flame shaped element;
a second magnetic-attractable material on a second side of a bottom portion of the flame shaped element;
where the first material and the second material are on opposite ends of the bottom of the flame shaped element symmetrically disposed relative to one another.
15. The electric lighting device of claim 13 , wherein the electromagnet concentrically surrounds the bottom portion of the flame shaped element.
16. The electric lighting device of claim 13 , further comprising a light source positioned to produce light on to the flame element.
17. The electric lighting device of claim 16 , wherein the light source is disposed entirely within the candle body, and the candle body is sealed.
18. The device as in claim 17 , wherein the light source emits said light via an aperture in the upper surface.
19. The device as in claim 17 , wherein the light source emits said light via an aperture in the upper surface.
20. The electric lighting device of claim 13 , wherein the flame shaped element includes inner surfaces defining a hollow interior portion and the retaining structure includes a flexible extension arm, attached to the support, that presses against inner surfaces of the flame element to hold the inner surfaces of the flame element from coming off of the support.
21. The electric lighting device as in claim 13 , wherein the flame shaped element includes inner surfaces defining a hollow interior portion and the retaining structure includes an insert that is inserted into the inner surfaces of the flame element after the flame element is inserted onto the support.
