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.

Claims

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 an upper surface intersecting the sidewall and 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 so that the upper portion at least partially aligns with the through hole of the outer shell;

wherein the upper portion of the core includes a cradle;

a flame component,

wherein an upper portion of the flame component further is shaped to look like a flame;

wherein the top portion shaped to look like a flame includes a depression;

a lighting element contained within an interior of the core and positioned at least partially on the cradle at an angle with respect to a longitudinal central axis of the core;

the angle of the lighting element allowing light from the lighting element to strike the flame component shaped to look like a flame;

the lighting element formed of one or more LEDs;

the one or more LEDs energized to emit 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 house one or more batteries, and the base of the core including a PCB;

the PCB electrically connects the one or more batteries to a control circuit and the control circuit to the lighting element in order to supply power to the control circuit and 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.
