1. Technical Field
The present disclosure relates to electronic candles.
2. Description of Related Art
Electronic candles that have the shape and pattern of a conventional candle are widely used. The electronic candles are internally provided with illuminating devices emitting light outward to enhance the outer appearance. However, the conventional electronic candles are not interactive and cannot simulate a traditional candles flickering or being extinguished by the wind, thereby limiting the versatility of the conventional electronic candle.
The components of the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments of an electronic candle assembly. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.

The main body 10 has a hollow body 110 and a lid 120 releasably engageable with the body 110. A plurality of electronic candles 20 are arranged at a top surface 122 of the lid 120. In the embodiment, the main body 10 is a faux cake; the number of the electronic candles 20 is three.
The electronic candle 20 includes a base 210 and an illuminating device 220 fixed to a top end of the base 210. The base 210 is configured for stably setting the illuminating device 220 on the main body 10. The illumination device 220 has a candle flame shape and illuminates to provide a simulated lit wax candle effect. The illuminating device 220 can be a light emitting diode (LED) or any other electrical lamp.

The sensors 310 are configured for measuring velocities of air current traveling through the illuminating devices 220, and outputting the velocities of the air current as analog electrical signals. In the embodiment, each sensor 310 includes an anemometer 312. Referring to
The A/D convertor 320 is configured for converting the analog electrical signals into digital signals.
The storage unit 330 includes a random-access memory 332 and a read-only memory 334. The random-access memory 332 is configured for temporarily storing the digital signals. The read-only memory 334 is configured for storing predetermined velocity values, and predetermined modes that power the illuminating device 220. In the embodiment, the read-only memory 334 stores two predetermined velocity values V1 and V2 (V1<V2). The predetermined modes powering the illuminating device 220 include a constant power mode, an alternating power mode, and a power-off mode.
In the embodiment, when the illuminating device 220 is in the constant power mode, the power supply 40 supplies constant electrical power to the illuminating device 220 and the illuminating device 220 illuminates steadily. When in the alternating power mode, the power supply 40 supplies the illuminating device 220 with alternating power, the illuminating device 220 flickers. When in the power-off mode, the power supply 40 stops supplying the power to the illuminating device 220, the illuminating device 220 turns off.
The processor 330 is configured for comparing the digital signal, corresponding to the measured velocity value, with predetermined velocity values, and controlling the illuminating device 220 to illuminate in a predetermined mode according to a comparing result. In detail, firstly, the processor 340 first reads the digital signal and the predetermined velocity value, and then compares the digital signal and the predetermined velocity value, and finally the power supply 40 controls the illuminating device 220 to illuminate in a predetermined mode.
For example, a velocity value V is measured by the sensors 310, when V is larger than V2, the processor 340 controls the power supply 40 to power-off the illuminating device 220. In detail, the processor 340 controls the power supply 40 to stop supply the electrical power to the illuminating device 220, that is, the illuminating device 220 is turned off.
When V is less than V1, the processor 340 controls the power supply 40 powering the illuminating device 220 in a constant power mode, in detail, the processor 340 controls the power supply 40 to continue the power to the illuminating device 220 steadily.
When V is larger than or equal to V1, and is less than or equal to V2, the processor 340 controls the power supply 40 powering the illuminating device 220 in an alternating power mode. In detail, the processor 340 controls the power supply 40 to supply the illuminating device 220 with an alternating power, thus, the illuminating device 220 flickers in response to the alternating power.
In operation, the electronic candle 100 can automatically turn off the illuminating device 220 when the illuminating device 220 is subjected to a strong air current blowing on it. For example, when a person blows on the illuminating device 220, the air current travels through the illuminating device 220 with a velocity V (V>V2). The sensors 310 measure the velocity V and output to the processor via the A/D convertor 320. The processor 340 compares the velocity V with the predetermined values V1 and V2. The processor 304 controls the power supply 40 to power-off the illuminating device 220 according to the comparison.
