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 one portion of the pendulum is disposed within the housing. At least one support member is fixedly coupled to both the housing and the pendulum, and is configured to support pivotal movement of the pendulum and the 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.

Claims

1. An illumination device, comprising:

a housing defining an interior region;

a light source;

a pendulum supporting the light source, at least a portion of the pendulum disposed within the interior region of the housing;

at least two support members configured to allow pivoting movement of the pendulum, the at least two support members each fixedly coupled to the pendulum and fixedly coupled to the housing, and the at least two support members each including a wire comprised of non-metallic and non-rigid material; and

a driving device coupled to the pendulum and configured to produce the pivoting movement of the pendulum.

2. The device of claim 1, further comprising inserts coupled to first end portions of the at least two support members;

and

wherein the pendulum defines channels, each of the inserts configured to engage at least partly within a respective one of the channels to thereby fixedly couple the at least two support members to the pendulum.

3. The device of claim 2, wherein the inserts each include first and second members configured to snap fit together generally around the first end portion of a respective one of the support members, to thereby couple to the first end portion of the respective one of the support members.

4. The device of claim 1, wherein the wire of each of the at least two support members includes a diameter of about one millimeter or less.

5. The device of claim 1, wherein the wire of each of the at least two support members includes a diameter of about 0.5 millimeters or less.

6. The device of claim 1, further comprising:

a printed circuit board attached to the pendulum, to thereby pivotally move with the pendulum during operation of the illumination device;

a light source controlling unit for controlling operation of the light source; and

wires configured to electrically connect the printed circuit board to the light source controlling unit and/or the driving device.

7. The device of claim 6, wherein the wires configured to electrically connect the printed circuit board to the light source controlling unit and/or the driving device each include a diameter of about 0.5 millimeters or less;

and/or

wherein the wires configured to electrically connect the printed circuit board to the light source controlling unit and/or the driving device each comprise a lacquered wire and/or a metal wire without any coating.

8. The device of claim 6, wherein the light source controlling unit comprises programmable software configured to control operation of the light source.

9. The device of claim 6, wherein the light source is a first light source;

and

further comprising at least a second light source;

wherein the printed circuit board is configured to respectively control light intensity and/or color of each of the first light source and the at least a second light source.

10. 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.

11. The device of claim 10, 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.

12. An electric candle, comprising:

a housing;

a flame-shaped head;

at least one light source disposed within the flame-shaped head;

a pendulum supporting the at least one light source;

first and second support members coupled to the pendulum and to the housing to support pivoting movement of the pendulum relative to the housing;

first and second inserts coupled to first end portions of the respective first and second support members, the inserts configured to couple the support members to the pendulum;

first and second mounts coupled to second end portions of the respective first and second support members, the mounts configured to couple the support members to the housing; and

a driving device coupled to the pendulum and configured to produce the pivoting movement of the pendulum.

13. The electric candle of claim 12, wherein the pendulum includes a first protrusion extending from a first side portion of the pendulum and defining a channel configured to receive the first insert, to thereby couple the first support member to the pendulum;
