Abstract

An electronic flameless candle including a body having a top surface, a bottom surface, a sidewall between the top surface and the bottom surface, and a cavity defined by the top surface, the bottom surface and the sidewall, the body configured in shape and size to simulate a true flame candle. The candle may also include a light source operably connected to the body, the light source electrically operated to illuminate in a way that simulates a natural flicker of a real candle flame. The candle may also include a scent component, operably connected to the body, the scent component configured to emit a scent when heated and/or a sensor component, operably connected to the body, the sensor component configured to sense an environmental condition and affect a mode of the light source upon the sensing of the environmental condition.

Claims (25)

1. An electronic flameless candle, comprising:

a body comprising a top surface, a bottom surface, a sidewall between the top surface and the bottom surface, and a cavity defined by the top surface, the bottom surface and the sidewall, the body configured in shape and size to simulate a true flame candle;

a light source operably connected to the body and positioned to be generally flush with an exterior surface of the body, the light source electrically operated to illuminate in a way that simulates a natural flicker of a real candle flame; and

a control switch comprising the light source, wherein at least a portion of the control switch is configured in shape and size to simulate a true flame candle's wick, the portion of the control switch simulating a true flame candle's wick extending distally from the top surface.

2. The electronic flameless candle of claim 1 , wherein the light source comprises a LED.

3. The electronic flameless candle of claim 1 , wherein the light source receives a random digital signal, the random digital signal varying in at least one of amplitude, frequency, and duty cycle.

4. The electronic flameless candle of claim 3 , wherein the random digital signal forms part of a pulse-width modulation signal.

5. The electronic flameless candle of claim 1 , wherein one or more of the top surface and sidewall are partially transparent.

6. The electronic flameless candle of claim 1 , wherein the control switch is a push button control switch.

7. The electronic flameless candle of claim 1 , wherein at least a portion of the control switch comprises a sheath surrounding at least a portion of the light source.

8. The electronic flameless candle of claim 7 , wherein the sheath is at least semitransparent.

9. The electronic flameless candle of claim 8 , wherein the control switch further comprises a wick component that is substantially black in color.

10. The electronic flameless candle of claim 9 , wherein the light source comprises a LED.

11. The electronic flameless candle of claim 1 , wherein the cavity defines an area configured to allow light emanating from the light source to illuminate the sidewall from within the cavity.

12. An electronic flameless candle, comprising:

a body comprising a top surface, a bottom surface, a sidewall between the top surface and the bottom surface, and a cavity defined by the top surface, the bottom surface and the sidewall, the body configured in shape and size to simulate a true flame candle;

a LED light source operably connected to the body and located such that at least a portion of the LED light source is positioned in an opening of the top surface where an interior and an exterior of the top surface of the body meet, the light source electrically operated to illuminate in a way that simulates a natural flicker of a real candle flame; and

a control switch comprising the LED light source, wherein at least a portion of the control switch is configured in shape and size to simulate a true flame candle's wick, the portion of the control switch simulating a true flame candle's wick extending distally from the top surface.

13. An electronic flameless candle, comprising:

a body comprising a top surface, a bottom surface, a sidewall between the top surface and the bottom surface, and a cavity defined by the top surface, the bottom surface and the sidewall, the body configured in shape and size to simulate a true flame candle; and

an artificial wick comprising a LED light source operably connected with a wick component configured in shape and size to simulate a true flame candle's wick, the wick component extending distally from the exterior surface of the body;

wherein the artificial wick operates as at least part of a push button control switch for the candle.

14. The electronic flameless candle of claim 13 , wherein the cavity defines an area configured to allow light emanating from the LED light source to illuminate the sidewall from within the cavity.

15. The electronic flameless candle of claim 13 , wherein the artificial wick comprises an at least partially transparent sheath that at least partially encapsulates the light source.

16. The electronic flameless candle of claim 15 , wherein the wick component is substantially black in color.
