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 comprising:

an enclosure provided with a through hole on an upper surface;

a flame component shaped in appearance to substantially resemble a shape of a flame when viewed from at least one perspective, the flame component supported to be exposed above the upper surface of the enclosure through the through hole of the enclosure;

at least one light-emitting element contained entirely within an interior of the enclosure and positioned such that an outgoing direction of a light from the light-emitting element is projected from within the interior of the enclosure, through the through hole of the upper surface of the enclosure, and onto at least one surface of the first portion of the flame component, thereby illuminating the flame component from a light source external to the flame component;

wherein the at least one light-emitting element comprises one or more LEDs;

wherein the enclosure comprises at least two enclosure elements operably configured to connect together to form the enclosure;

wherein at least one of the enclosure elements comprises a cradle on its sidewall forming an installation location for one or more of the at least one light-emitting element, wherein the installation location is operably configured to allow the at least one light-emitting element to emit light at a direction towards the through hole;

an electrically-powered driving mechanism, disposed opposite an end of the enclosure from the through hole; and

a base coupled to the enclosure and below the enclosure comprising a battery chamber structured to contain one or more batteries;

wherein the battery chamber further includes a door on a bottom surface;

control circuitry;

wherein the battery chamber includes connectors electrically connected to the control circuitry, the control circuitry electrically connected to the electrically-powered drive mechanism and the at least one light-emitting element;

wherein the control circuitry is installed adjacent to the battery chamber;

wherein the control circuitry includes one or more printed circuit boards;

wherein the control circuitry includes a timer to discontinue power after a predetermined amount of time.
