Abstract

An illumination device (e.g., an electric candle, etc.) generally includes a housing, a light source, and a pendulum supporting the light source. At least a portion of the pendulum is disposed within the housing. A support member is coupled to both the housing and the pendulum, and is configured to support pivotal movement of the pendulum and light source relative to the housing. And, a driving device is coupled to the pendulum, at a location within the housing, and is configured to produce the pivotal movement of the pendulum.

6. The device of claim 1, further comprising a flame-shaped head coupled to the pendulum, the light source disposed within the flame-shaped head and configured to transmit light through the flame-shaped head to thereby provide a flame effect to the illumination device.

7. The device of claim 6, further comprising a color element disposed within the flame-shaped head and positioned over at least part of the light source for creating a color effect in the flame-shaped head when the light source transmits light through the color element and the flame-shaped head.

8. The device of claim 1, wherein the light source is coupled to the pendulum toward a first end portion of the pendulum, the pendulum including a mount located toward a second end portion of the pendulum opposite the first end portion, the driving device disposed within the mount of the pendulum such that the pivotal movement of the pendulum also moves the driving device.

9. The device of claim 1, wherein the driving device comprises a motor.

10. The device of claim 1, further comprising:

a printed circuit board disposed within the housing and electrically coupled to the light source and/or the driving device for controlling operation of the light source and/or the driving device;
