1. An electric light that simulates a flickering flame, comprising:
- a housing;
an elongated circuit board disposed within the housing and having a projection at a first end, wherein the housing includes first and second internal projections that couple to first and second sides of the circuit board such that a position of the circuit board relative to the housing is maintained;
an electromagnet coupled to the projection, wherein the projection helps maintain a horizontal position of the electromagnet relative to the circuit board, and wherein the electromagnet is configured to produce a magnetic field;
a pendulum pivotally mounted within the housing above the elongated circuit board and having (i) a magnet on a second end that interacts with the magnetic field thereby causing movement of the pendulum with respect to the housing, and (ii) a flame-shaped element on a first end opposite the second end; and
a light source disposed within the housing such that light from the light source is emitted onto a face of the flame-shaped element.

Abstract
Various embodiments of electric lighting devices, and in particular, electric candles are described. The devices can include a flame element onto which light can be projected from a light source. Preferably, the light is projected within a focal area on the flame element. The housing of the devices can include projections that help maintain a vertical position of a circuit board within the housing.

7. An electric light that simulates a flickering flame, comprising:
-
a housing having left and right sides, each of which comprises one or more internal projections that collectively maintain a position of a circuit board relative to the housing when the left and right sides are coupled together, and the circuit board is disposed between the left and right sides within the housing; wherein an electromagnet that generates a magnetic field is disposed about a projection of the circuit board such that a position of the electromagnet relative to the circuit board is maintained; a pendulum having a flame-shaped element at a first end and a magnet at a second end, and movably coupled to the housing, wherein the magnet interacts with the magnetic field thereby causing movement of the pendulum; and a light source disposed within the housing such that light from the light source is emitted onto a face of the flame-shaped element. - View Dependent Claims (8, 9, 10)

11. An electric light that simulates a flickering flame, comprising:
-
a housing that comprises left and right sides, each of which comprises one or more internal projections that collectively maintain a vertical position of a circuit board relative to the housing when the left and right sides are coupled together, and wherein the internal projections comprise V-shaped indentations, and wherein left and right sides of the circuit board are configured to rest within a valley of the indentations of the left and right sides of the housing; a flame element pendulum pivotally coupled to the housing; a drive mechanism disposed within the housing directly below the flame element pendulum and configured to cause movement of the flame element pendulum with respect to the housing while maintaining a vertical position and a horizontal position of the drive mechanism; a light source disposed within the housing and configured to emit light toward the flame element pendulum; a lens configured to intercept at least some of the light emitted from the light source and focus the intercepted light onto the flame element pendulum to generate a focal area of light, wherein the focal area covers a central portion of the flame element pendulum at rest; and wherein the flame element pendulum comprises an outer border about the central portion, and wherein the outer border is sized such that the focal area of light always remains on a surface of the flame element pendulum as the flame element pendulum moves with respect to the housing. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
