And the light is changed by changing the position of the light spot on the flame portion 11.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic candle, and more particularly to an electronic candle that can obtain a variable light.

[0002]

[Prior art]

 A candle with a flammable wick wrapped around it in a cylindrical shape has been used for lighting since ancient times. If you accidentally fall, you may inadvertently burn to another thing and become important.

For this reason, various attempts have been made to attach a miniature bulb to the upper part of a white cylinder such as a candle to light it, or to provide a neon bulb to discharge the light.

[0004]

[Problems to be solved by the device]

 As described above, in the case of lighting a miniature light bulb as a light emitter, the position of the light source does not change and the brightness does not change, so the atmosphere like the lighting of an actual candle is lacking, and neon bulbs are used. In this case, the brightness flickers due to fluctuations in the discharge part, but there is the problem that a high-voltage power supply is required.

The present invention has been made in view of the above problems, and an object thereof is to provide an electronic candle that can obtain a change in brightness like a flame of an open flame and does not require a high voltage power source. It's about trying.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, according to the present invention, there is provided an electronic candle in which a light emitting part having a lamp is attached above an elongated cylinder serving as a base part of a candle, and the lamp is energized to illuminate the light emitting part. There is provided an electronic candle including a plurality of lamps housed in a light emitting portion and a control circuit arranged in the base portion and repeatedly outputting a number of lighting signals corresponding to the number of lamps.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the configuration of an embodiment of an electronic candle according to the present invention, and FIG. 2 is a circuit diagram in this embodiment.

In these drawings, reference numeral 1 denotes a light emitting portion, which is made of a semi-transparent synthetic resin material molded product, and an upper portion thereof is formed with a flame portion 11 in which a normal candle is ignited to generate a flame. Then, the insertion portion 12 including the plurality of contact pieces and the guide key 15 is arranged in the lower portion, and is inserted above the base body portion 2.

Inside the flame portion 11, for example, three lamps 11a, 11b, 11c provided with filaments are housed, and one side line of each of them is used as a common line and the contact pieces 12a, 12b, 12c and 13 (common line).

The base portion 2 is a cylindrical body made of a milky white synthetic resin material, and a socket portion 21 that engages with the insertion portion 12 of the light emitting portion 1 and energizes the lamp is provided on the upper end surface of the base portion 2. A control circuit 3 for controlling the energization of the lamp is housed in the inside of the shape, and a plurality of wax drop patterns 22 which are formed on the outer circumference of the actual candle are formed on the outer wall above the base portion 2. There is.

Then, the socket portion 21 is contacted with the contact pieces 12 a, 12 b, 12 c and 13 of the insertion portion 12 to supply electric power, and four contact points 23 are engaged with the guide key 15 to cause erroneous contact. A guide groove 24 for preventing the above is provided, and the four contacts 23 are respectively connected to the outputs from the control circuit 3.

FIG. 2 is a circuit diagram showing an example of a control circuit, which includes a rectifier circuit, an oscillation circuit, a counter circuit, a drive circuit, and the like, and a signal from the oscillation circuit is input to the counter circuit to generate a ternary signal. The signal is controlled, and this is energized to the three lamps via the drive circuits, respectively, and the three lamps are sequentially turned on.

The circuit of FIG. 2 will now be described. The input from the AC power source is full-wave rectified by D ₁ and connected to the common line of the three lamps, and at the same time by C ₁ via D _2. It is smoothed and becomes a power source for IC circuits and the like.

On the other hand, the output from the oscillation circuit by IC _1a and IC _{1b formed} of NAND gates is input to IC ₂ connected as a ternary counter, and the ternary output from IC ₂ is Q for driving. _1, Q _2, Q ₃ sequentially lamp 11a as a pulsating flow through, 11b, is configured to turn on the 11c.

Next, the operation of the present embodiment configured as described above will be described.

The guide key 15 of the insertion portion 12 is engaged with the guide groove 24 of the base portion 2 to mount the light emitting portion 1 above the base portion 2, and then a predetermined AC power source is supplied to the lead wire 25.

In the control circuit 3 to which power is supplied, the alternating current is rectified into direct current power as described above, and the lamps 11a, 11b and 11c are sequentially turned on by the operation of the oscillation circuit and the counter circuit. Since the positions of the flickering filaments inside the flame part 11 of the light emitting part 1 are different, the position of the light source moves and flickers, and the light fluctuates like a real candle flame. It will give you the feeling of going out.

Although the present invention has been described with reference to the above-described embodiments, various modifications and applications are possible within the scope of the gist of the present invention, for example, by changing the number of lamps stored in the flame portion. Modifications and applications of are not excluded from the scope of the present invention.

[Effect of device]

 According to the present invention as in the above-described embodiment, three lamps are housed in a flame-shaped flame portion as a light-emitting portion of a candle, and the lamp is turned on / off sequentially from a control circuit having an oscillation circuit and a counter circuit. Since the three kinds of signals to be turned off are energized to turn on the three lamps in sequence, the light spot of the flame part that uses these lamps as a light source moves and the brightness changes, as if a candle flame The effect is that the atmosphere is swaying in the wind, and it does not cause a fire because it is not an actual combustion, and it does not require a high voltage for the power supply.
