Abstract

An electronic lighting device and a method for manufacturing the same are disclosed. The electronic lighting device may comprise a core, which may comprises an enclosure, a light-emitting element, a flame sheet and a swing mechanism. The flame sheet is movably supported or suspended on the enclosure, and may comprise an upper sheet which is of a flame-like shape. The upper sheet is configured to expose above the top of the enclosure. The light-emitting element may be installed on the enclosure. A light outgoing direction of the light-emitting element may be intersected with the surface of the upper sheet so that the light of the light-emitting element is projected on the surface of the upper sheet. The swing mechanism is disposed beneath the flame sheet and can apply a force on the flame sheet to actuate the flame sheet to sway or swing. By the present application, a visual experience of true fire can be achieved and an interestedness and appreciation can be improved.

First claim

What is claimed is:

1 . An electronic lighting device for simulating a candle, comprising:
an outer shell having a shape to resemble a candle and including a curved sidewall spanning around a perimeter of the outer shell and including an upper surface intersecting the curved sidewall and said outer shell having a through hole; a core, contained within the outer shell, and structured to include an upper portion, a support, and a base; the upper portion of the core oriented to at least partially align with the through hole of the outer shell; wherein the upper portion of the core includes a cradle; wherein the upper portion of the core further includes a top portion shaped to look like a flame; wherein the top portion shaped to look like a flame includes a depression in a face of the top portion; a lighting element, contained within an interior of the core, and positioned at least partially on the cradle at an angle with respect to an axis passing through the cradle and a longitudinal central axis of the core; the angle of the lighting element effective to allow light from the lighting element to strike the top portion shaped to look like a flame; the lighting element consisting of one or more LEDs; the one or more LEDs energized for emitting blinking light from within the interior of the core onto the top portion shaped to look like a flame through the through hole and onto the depression; the base of the core including a battery compartment to contain one or more batteries and a printed circuit board (PCB); a control circuit; the PCB electrically connects the one or more batteries to the control circuit and connects the control circuit to the lighting element in order to supply power to the control circuit and to energize the lighting element; the battery compartment further including a door on a bottom surface of the core; the control circuit configured to cause the one or more LEDs to emit the blinking light on the top portion shaped to look like a flame; and the control circuit including a timer to discontinue power to the light emitting element after a predetermined amount of time.
