In one example aspect, an electronic candle includes a mounting frame that includes a first connector and a power supply assembly that is detachable from the mounting frame. The power supply assembly includes a second connector that forms a coupling mechanism with the first connector. The power supply assembly further includes an energy storage, a first power source configured to charge the energy storage, and an electrical connection interface configured to connect the power supply assembly to a second power source. The electronic candle also includes a light-emitting assembly that is removably coupled to the mounting frame configured to operate using power provided by the power supply assembly, and one or more controllers configured to control an operation of the light-emitting assembly. ## Claims ### Claim 1 A lighting device, comprising: a mounting frame that comprises: a base, a mounting top, and multiple pillars, wherein a first end of the multiple pillars is connected to the base and a second end of the multiple pillars is connected to the mounting top; a power supply assembly that comprises: a rechargeable battery, and a solar panel coupled to the mounting top, wherein the solar panel is configured to charge the rechargeable battery when solar energy is available, wherein the power supply assembly is coupled to and decoupled from the mounting frame using a connector without moving or titling the mounting frame; a candle-shaped light-emitting assembly removably coupled to the mounting frame independent of the power supply assembly, wherein the candle-shaped light-emitting assembly is positioned within a cavity formed by the multiple pillars of the mounting frame, wherein the candle-shaped light-emitting assembly comprises at least one Light-Emitting Diode (LED) and is configured to operate using power provided by the power supply assembly; and one or more controllers configured to control a mode of operation of the candle-shaped light-emitting assembly. ### Claim 2 (depends on 1) The lighting device of claim 1, wherein the mounting frame further comprises: multiple surfaces, each configured to connect two adjacent pillars of the multiple pillars, wherein the multiple surfaces comprise a transparent or translucent material. ### Claim 3 (depends on 1) The lighting device of claim 1, wherein at least the power supply assembly is water resistant. ### Claim 4 (depends on 1) The lighting device of claim 1, wherein the mode of operation comprises at least setting a timer for the lighting device. ### Claim 5 (depends on 1) The lighting device of claim 1, wherein the candle-shaped light-emitting assembly comprises a frame sheet that resembles a shape of a real flame. ### Claim 6 (depends on 1) The lighting device of claim 1, further comprising a sensor, wherein the one or more controllers are configured to change the mode of operation of the candle-shaped light-emitting assembly based on a signal from the sensor. ### Claim 7 (depends on 1) The lighting device of claim 1, wherein the solar panel is positioned on top of the mounting frame. ### Claim 8 (depends on 1) The lighting device of claim 1, wherein the power supply assembly comprises an electrical connection interface configured to connect the power supply assembly to a second power source, wherein the electrical connection interface comprising a Universal Serial Bus (USB) Type-C interface, a Lightning interface, a USB2.0 interface, or a USB3.0 interface. ### Claim 9 (depends on 1) The lighting device of claim 1, wherein the power supply assembly includes an aperture that is configured to be coupled to the connector of the mounting frame upon attachment of the power supply assembly to the mounting frame and to be decoupled from the connector upon detachment of the power supply assembly from the mounting frame. ### Claim 10 (depends on 1) The lighting device of claim 1, comprising: a touch switch configured to turn on or off the lighting device. ### Claim 11 (depends on 1) The lighting device of claim 1, wherein the one or more controllers are configured to turn off the candle-shaped light-emitting assembly after a predetermined amount of time. ### Claim 12 (depends on 1) The lighting device of claim 1, wherein a color of the at least one LED is close to a color of fire. ### Claim 13 (depends on 1) The lighting device of claim 1, further comprising: a light detection device configured to detect an intensity of an ambient light, wherein the one or more controllers are configured to turn on or off the lighting device based on the detected intensity of the ambient light. ### Claim 14 (depends on 1) The lighting device of claim 1, further comprising: an infrared receiver configured to receive an infrared signal that enables a remote control of the lighting device.
