Abstract

An illumination device (e.g., an electric candle, etc.) generally includes a housing, a light source, and color element. The color element is positioned over at least part of the light source for creating a color effect in the electric candle when the light source transmits light through the color element. The illumination device may also include a pendulum supporting the light source, and a support member configured to support pivotal movement of the pendulum and light source relative to the housing.

Claims

1. An electric candle, comprising:

a housing;

a light source;

a color element positioned over at least part of the light source for creating a color effect in the electric candle when the light source transmits light through the color element; and

a flame-shaped head, the light source and the color element disposed within the flame-shaped head, and the light source configured to transmit light through the color element and the flame-shaped head to thereby provide a flame effect to the illumination device having the color effect.

2. The electric candle of claim 1, wherein the color element includes a generally translucent and tube-shaped sleeve.

3. The electric candle of claim 1, wherein the color element is generally blue.

4. The electric candle of claim 1, further comprising a pendulum supporting the light source and the color element, the pendulum pivotally coupled to the housing and configured to move the light source and the color element relative to the housing.

5. The electric candle of claim 4, further comprising a support member coupled to the housing and the pendulum for pivotally coupling the pendulum to the housing, the pendulum configured to pivot relative to the housing, via the support member, to thereby move the light source and the color member relative to the housing.

6. The electric candle of claim 5, wherein the housing defines an interior region, and wherein the support member includes a wire extending through the interior region of the housing, the wire including a diameter of about one millimeter or less.

7. The electric candle of claim 4, further comprising a driving device disposed within the housing and configured to produce pivotal movement of the pendulum;

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 including a motor disposed within the mount of the pendulum such that the pivotal movement of the pendulum also moves the motor.

8. The electric candle of claim 1, further comprising a driving device disposed within the housing and configured to produce movement of the color element and the light source relative to the housing.

9. The electric candle of claim 1, further comprising a printed circuit board disposed within the housing and electrically coupled to the light source for controlling operation of the light source.

10. The electric candle of claim 9, further comprising a pendulum supporting the light source and the color element, the pendulum pivotally coupled to the housing and configured to move the light source and the color element relative to the housing;

wherein the printed circuit board is coupled to the pendulum and is configured to move with the pendulum.

11. The electric candle of claim 10, further comprising a printed circuit board assembly for providing power to the electric candle and for controlling operation of the electric candle, through the printed circuit board;

and

at least two wires electrically connecting the printed circuit board to the printed circuit board assembly, each of the at least two wires including a diameter of about 0.5 millimeters or less, to avoid impact to the pivotal movement of the pendulum.

12. The electric candle of claim 10, further comprising a light source controlling unit for controlling operation of the light source;

and at least one wire electrically connecting the light source to the light source controlling unit through the printed circuit board, the at least one wire including a diameter of about 0.5 millimeters or less, to avoid impact to the pivotal movement of the pendulum.

13. An electric candle, comprising:

a housing;

a light source;

a pendulum supporting the light source, the pendulum pivotally coupled to the housing and configured to move the light source relative to the housing;

a driving device configured to produce pivotal movement of the pendulum to thereby move the light source relative to the housing;
