Abstract

Various components for artificial candles and other lighting devices are described that can be used to create a realistic flame effect in the devices. The devices include a flame element that extends upwardly from a housing. A light source can be disposed with respect to the flame element such that the flame element is illuminated. A variety of drive mechanisms could be disposed within the body of the device that can cause movement of the flame element with respect to the housing. The flame element can be coupled to a housing or mounting bracket of the device using various components to suspend the flame element within the housing.

First claim

What is claimed is:

1. An electronic lighting device, comprising:
an elongated housing having an elongated shape;
an elongated element movably positioned within the elongated housing, the elongated element comprising at least a flame-shaped portion that is shaped to resemble a flame extending outside of the elongated housing,
wherein the elongated element has multiple different transparency amounts such that an upper portion of the flame-shaped portion is more transparent than a lower portion of the flame-shaped portion;

a drive mechanism positioned below the elongated element configured to drive a movement of the elongated element to simulate a moving flame; and
a light source configured to emit one or more colors of light onto the upper portion of the elongated element to simulate a color of a candle flame.

2. The electronic lighting device of claim 1 , wherein the flame-shaped portion of the elongated element comprises one or more materials having varying levels of transparency.

3. The electronic lighting device of claim 1 , wherein the elongated element has a varying thickness such that different amounts of the light emitted from the light source pass through different portions of the elongated element.

4. The electronic lighting device of claim 1 , wherein the elongated element has an asymmetric shape.

5. The electronic lighting device of claim 1 , wherein the drive mechanism comprises an electromagnet or a fan.

6. The electronic lighting device of claim 1 , wherein the elongated housing comprises:
an elongated outer shell; and
an opaque layer positioned within the elongated outer shell configured to surround an interior perimeter of the elongated outer shell to prevent the light from the light source from being seen through the elongated outer shell.

7. The electronic lighting device of claim 1 , further comprising:
a lens positioned between the light source and the upper portion of the elongated element and within the elongated housing, wherein the lens is configured to focus the light emitted from the light source.

8. The electronic lighting device of claim 7 , wherein a focal length of the lens is greater than a distance between the lens and the upper portion of the elongated element to provide soft lighting on the elongated element.

9. The electronic lighting device of claim 1 , wherein the elongated housing comprises:
a mounting bracket that has a groove to position the light source.
