Abstract

Various embodiments of electric candles are described having multiple flame elements, each of which generate a flickering flame effect, and collectively simulate a candle having multiple flames. The candles include a housing that encloses various lighting devices and circuitry that can control one or more aspects of the lighting devices. The enclosure can also house one or more drive mechanisms that help to effect movement of the flame elements (e.g., pivot or wobble) relative to the enclosure.

First claim

What is claimed is:

1. A multi-flame electric candle comprising:
an enclosure having first and second apertures on a top surface;
first and second artificial flame elements protruding through the first and second apertures, and coupled to the enclosure such that each of the first and second artificial frame elements may move with respect to the enclosure;
first and second light sources positioned and oriented within the enclosure to project light onto the first and second artificial frame elements through the first and second apertures, respectively;
circuitry to coordinate light projection from the first and second light sources, wherein the circuitry causes the first and second light sources to project light according to a program stored to the circuitry; and
wherein the circuitry comprises a circuit to sense a movement in each of the first and second artificial frame elements.

2. The multi-flame electric candle of claim 1 , wherein the circuit to sense movement is a Hall effect sensor.

3. The multi-flame electric candle of claim 1 , wherein the program causes the first and second light sources to project light at varying intensities based on the sensed movement in the first and second artificial frame elements, respectively.

4. The multi-flame electric candle of claim 1 , wherein the program causes the first light source to turn off upon sensing a sufficient movement of the first artificial flame element.

5. The multi-flame electric candle of claim 1 wherein the third light source projects light of a different color than the first light source onto the first artificial element, and fourth light source projects light of a different color than the second light source onto the second flame element.

6. The multi-flame electric candle of claim 5 , further comprising fifth and sixth light sources positioned and oriented within the enclosure to project light onto the first and second artificial flame elements through the first and second apertures, respectively.

7. The multi-flame electric candle of claim 6 , wherein the fifth light source projects light of a different color than the first and third light sources onto the first artificial flame element, and sixth light source projects light of a different color than the second and fourth light sources onto the second artificial frame element.

8. The multi-flame electric candle of claim 6 , further comprising fifth and sixth light sources positioned and oriented within the enclosure to project light onto the first and second artificial frame elements through the first and second apertures, respectively, wherein the first, third, and fifth light sources are arranged around the first artificial flame element and the second, fourth, and sixth light sources are arranged around the second artificial flame element.

9. A multi-flame electric candle comprising:
an enclosure having first and second apertures on a top surface;
first and second artificial flame elements protruding through the first and second apertures, and coupled to the enclosure such that each of the first and second artificial flame elements may move with respect to the enclosure;
first and second light sources positioned and oriented within the enclosure to project light onto the first and second artificial flame elements through the first and second apertures, respectively; and
circuitry to coordinate movement of the first and second artificial flame elements, wherein the circuitry causes the first and second artificial flame elements to move according to a program stored to the circuitry.

10. The multi-flame electric candle of claim 9 , wherein the first artificial flame element is a master element, the second and third artificial flame are slave artificial flames, and the circuitry primarily coordinates movement of the master artificial frame element resulting in movement of the slave artificial flame elements.

11. The multi-flame electric candle of claim 1 , wherein the program comprises a plurality of profiles that each cause the first and second artificial flame elements to move differently according to a selected profile.

12. The multi-flame electric candle of claim 1 , wherein the circuitry is further configured to coordinate projection of light from the first and second light sources with movement of the first and second artificial flame elements, respectively.

13. A multi-flame electric candle comprising:
an enclosure having first and second apertures on a top surface;
first and second artificial flame elements protruding through the first and second apertures, and couple to the enclosure such that each of the first and second artificial flame elements may move with respect to the enclosure;
first and second light sources positioned and oriented within the enclosure to project light onto the first and second artificial flame elements through the first and second apertures, respectively; and
circuitry to coordinate movement of the first and second artificial flame elements with the projection of light from the first and second light sources, respectively, according to a program stored to the circuitry.
