Electronic candle

This creation is about a candle light, especially an electronic candle.

Although candles are not the main lighting tools of modern people, they are often used in various religious rituals, or simply placed on the table to add atmosphere.

However, since candles emit toxic substances during their production and use, they are disposable consumables and cannot be reused, thus polluting the environment.

In order to replace the traditional candle, there are a variety of analog candle-operated and electrically powered candle lamps circulating on the market. Referring to Figure 8, an existing candle lamp has a barrel casing 80 and an LED lamp 90.

The barrel base 80 has a top surface 81, a bottom surface 82 opposite to the top surface 81, and a battery chamber 83. The battery chamber 83 is disposed on the bottom surface 82.

The LED lamp 90 has a drop-shaped lamp cover 91 and an LED lamp 92. The drop lamp cover 91 is disposed on the top surface 81 and defines a mask space therebetween. The LED lamp 92 is disposed in the mask space. And electrically connected to the battery chamber 83.

When the electronic candle lamp is used, the LED lamp 92 obtains the working power from the battery chamber 83 and starts to emit light, and then diverges through the drop lamp cover 91 to simulate the light emitted by the candle fire when the conventional candle is burned.

However, the drop lamp cover 91 is fixed on the top surface 81 of the base 80, and can only cooperate with the light emitted by the LED lamp 92 to simulate the shape of the candle fire when the conventional candle is burned, and cannot simulate the combustion. When the light and shadow of the candlelight shakes, it can be seen that there is still room for improvement in the plausibility of the electronic candle light.

In view of the defects of existing electronic candles, the main purpose of this creation is to provide an electronic candle.

The main technical means for achieving the above purpose is that the electronic candle lamp comprises: a hollow casing having an upper opening and a bottom surface opposite to the upper opening; and a movable reflector group having: a suspension a rod, the two ends of which are respectively connected to the inner wall surface of the hollow shell, and the suspension rod is bent toward the bottom surface of the hollow shell to form a V-shaped portion in the middle portion of the suspension rod; and a reflective sheet is suspended The suspension rod has a reflective end protruding from the upper opening, a magnetic sensing end opposite to the reflective end, and a through hole, wherein the magnetic sensing end is provided with a magnetic sensing member, and the through hole is formed on the reflective sheet and located at the Between the reflective end and the magnetic sensing end, the suspension rod is disposed therein; a circuit board is disposed on the bottom surface of the hollow housing, and the circuit board is provided with a coil, wherein when the circuit board is energized, the coil is A magnetic field that changes with time is generated; and an LED lamp is electrically connected to the circuit board, wherein the light emitting surface of the LED lamp faces the reflective end of the reflector.

When the electronic candle lamp of the present invention is operated, the coil on the circuit board generates a magnetic field, and the magnetic induction member on the magnetic sensing end of the reflective sheet is adsorbed or repelled by the magnetic field of the coil, so as to be suspended from the V-shaped portion. The reflector will approach or move away from the coil, and the magnetic field of the coil will change with time, so that the reflector is continuously shaken in the V-shaped portion, and the light emitted by the LED lamp is projected to the reflection protruding from the upper opening. On the end, therefore, the reflective end is reflected and swayed on the upper opening, so that the retroreflective sheeting of the electronic candle lamp of the present invention visually produces the effect of lighting and swaying like a candlelight.
