Description

  The present invention relates to a wax light-emitting candle, and more particularly, to a wax light-emitting candle that has a combustible core with a combustion flame and can emit light from the inside of the candle body.

A general candle is a candle body made of wax with a combustible core material embedded in it. By igniting the tip of the core material and burning it, the core material absorbs the dissolved wax from the candle body as fuel. However, a combustion flame is generated.
In recent years, for example, an “electronic candle” described in Patent Document 1, a plurality of light emitting diodes (LEDs) having different light emission colors are used as light sources, and light emission is performed while controlling the light emission time and light emission order by a control unit. What is to be known is known.
JP-A-2005-353415

However, in general candles with a burning flame, the core material fixed to the center of the candle body emits the burning flame while absorbing the dissolved wax. It was monotonous as a material that demonstrated its properties. For example, it was lacking in directing effect for a candle service performed at a wedding reception.
On the other hand, in the case of the “electronic candle” described in Patent Document 1, a plurality of electronic flames having different colors that cannot be expressed by the combustion flame or fluctuations similar to the combustion flame are determined by appropriately emitting light from the plurality of light emitting diodes. Although the light can be emitted in a predetermined order for a period of time, the healing effect of the soft orange burning flame, which is said to be the same as the color temperature of the sunset, cannot be obtained.
Moreover, in the case of an electronic candle, the deodorizing effect expressed by burning the odor source in the air of the combustion flame cannot be obtained. For this reason, even with an electronic flame, for example, the smell of cigarettes and pets trapped in the room cannot be removed.

  Therefore, as a result of diligent research, the inventor used a flammable optical fiber embedded in the candle body along the flammable core material, and the light of the light emitting unit in which the light of the combustion flame of the core material was embedded in the candle body. It is introduced into a sensor to detect this, and based on the detection signal, a plurality of light emitting diodes are caused to emit light within a predetermined time and in a predetermined order in accordance with a command from the light emitting circuit of the light emitting unit. If it was constituted, it was found that all the above-mentioned problems were solved, and this device was completed.

  This device provides a healing effect and a deodorizing effect as a general candle with a burning flame, and can emit light from the inside of the candle so that it can exhibit a decorative effect of light. The aim is to provide a light-emitting candle.

  The device according to claim 1 is a transparent or translucent container, a translucent candle body housed in the container and made of wax, and a length direction of the candle body in the length direction of the candle body. A combustible core material embedded toward the core, a combustible optical fiber embedded along the core material in the candle body, and a core material embedded in the candle body and introduced through the optical fiber. A light-emitting unit that illuminates the candle body by detecting light of the combustion flame, the light-emitting unit detects a combustion flame of the core material through the light-emitting diode that illuminates the candle body from the inside and the optical fiber The light sensor, a battery serving as a power source of the light emitting diode, and the light emitting diode by power of the battery based on a detection signal from the light sensor. A wax luminescent candle is obtained and a circuit board on which light emitting circuit which light is formed.

  The invention according to claim 2 uses a plurality of light emitting diodes having different emission colors as the light emitting diode, and the light emitting circuit causes the plurality of light emitting diodes to emit light in a predetermined order. This is a wax luminous candle.

  The invention according to claim 3 is obtained by pouring the melted wax into a mold containing the light emitting unit and cooling the candle body. And an outer casing that houses the photosensor, the battery, and the circuit board in an internal space, and the upper surface of the outer casing is made of a different wax from the wax for the candle body, 3. The wax light emitting candle according to claim 1 or 2, wherein a diode thermal deterioration preventing layer having a thickness for burying the light emitting diode is laminated.

  The invention according to claim 4 is the wax-emitting candle according to any one of claims 1 to 3, wherein the candle body is made of the wax containing a fragrance.

The material of the container is arbitrary as long as it is transparent or translucent. For example, various types of glass and various types of plastics can be used.
As the shape of the container, for example, a cup shape, a dish shape, or the like can be adopted.
The candle body is formed by molding wax into a predetermined shape, and a combustible core material is embedded with its tip projecting from the upper surface of the candle body.
As the candle body, natural waxes such as goby wax and urushi wax can be adopted in addition to artificial waxes such as paraffin wax and palm wax.
Aromas can be added to the candle body to make an aroma candle. As a fragrance | flavor, perfumes (aroma essence), such as rose, lavender, lemon, orange, can be employ | adopted, for example.

As the core material, for example, cotton yarn or rush can be employed.
As the optical fiber, it is possible to adopt a fiber having a heat loss property (a property that disappears due to combustion, combustibility) composed of a core and a grad having different light refractive indexes. By fixing the lower end of the optical fiber to the light receiving part of the light sensor of the light emitting unit, light from the core material (combustion light) is guided to the light sensor of the light emitting unit by the optical fiber, and the electric circuit is closed. And the light emitting diode emits light. The optical fiber is configured to always guide the ignition light of the core material to the optical sensor by gradually disappearing as the core material burns and disappears.
The outer peripheral surface of the optical fiber is covered with an opaque coating film so that light is not guided to the sensor through the outer peripheral surface. As the coating film, a paint film, a tape, or the like can be employed.

The light emitting unit is preferably one in which an electric system (light sensor, battery, circuit board, etc.) is housed in an outer casing. If comprised in this way, when embedding a light emitting unit in a candle main body with shaping | molding of a candle main body, deterioration of the electric system of the light emitting unit by the heat | fever of a wax can be prevented. Here, “accommodating the electrical system in the outer casing” includes a case where a part of the wall plate of the outer casing is also used as a circuit board. In this case, it is necessary to form the light emitting circuit on the back surface (inner surface) of the circuit board in order to avoid deterioration of the melted other wax due to heat.
Further, it is preferable that the light emitting diode is disposed outside the outer casing because the wax and the light emitting diode can be brought into contact with each other without interposing a space. In this way, the light of the light emitting diode generated in the candle body does not cause a local increase in luminous intensity due to the presence of space in the middle, and the light emitting diode is centered on the outer peripheral surface of the candle body. It is possible to produce natural light attenuation in which the light intensity gradually decreases.

  However, in order to obtain such a natural light attenuation effect within the candle body, as described above, the light emitting unit is embedded with the light emitting diode exposed inside the candle body simultaneously with the molding of the candle body. There is a need. At that time, the light emitting diode may be significantly (heated) deteriorated by the heat (60 ° C. or more) of a large amount of wax poured into the mold. Therefore, in order to suppress this, it is configured such that a diode thermal deterioration prevention layer made of a wax different from the wax for the candle body and having a thickness for burying the light emitting diode is laminated on the upper surface of the outer casing. It is better to do it. That is, the exposed light emitting diode is previously covered with a diode thermal deterioration preventing layer made of another wax having a smaller amount than that of the candle body. The size of the diode thermal deterioration preventing layer is not limited as long as the deposition is smaller than that of the candle body. ) Or a maximum of 10 mm longer than that.

  In this way, since the amount of wax used in the diode thermal deterioration prevention layer is smaller than that in the case of the candle body, thermal degradation due to melted wax of the light emitting diode is suppressed, and the light emitting diode is integrated with the wax. Can be embedded in the candle body. In addition, the diode thermal deterioration prevention layer is not made of plastic, for example, and is made of wax in the same manner as the candle body. Therefore, when the candle body is molded by placing the light emitting unit in the mold and casting the wax, The surface layer of the diode heat deterioration preventing layer is melted by heat, and the candle body and the diode heat deterioration preventing layer are integrated with no boundary surface. As a result, the light generated from the light emitting diode in the candle body described above gradually increases in luminous intensity toward the outer peripheral surface of the candle body, with the light emitting diode as the center, without causing a local light intensity increasing region in the middle. Natural attenuation of the light which falls can be produced more effectively. In addition, another reason why this diode thermal deterioration prevention layer has to be made using another wax as a raw material is that if it is made of plastic, the melting temperature of plastic is generally higher than that of wax. The thermal deterioration of the light emitting diode is promoted.

As the light emitting diode, either one emitting monochromatic light or one emitting multicolor light can be employed. Further, only one light emitting diode may be used, or a plurality of light emitting diodes having different emission colors may be used.
The embedding position of the light emitting unit in the candle body is arbitrary. However, in order to use wax effectively, the lower part of the candle body is generally preferred.
A photoelectric sensitivity element, a photoelectric conversion element, etc. are employable as an optical sensor.
As the battery, for example, a small battery such as a button battery is preferable because it can be stored compactly in the candle body.
The light emitting circuit controls the light emission of the light emitting diode by detecting the ignition light of the core material. Specifically, the light emitting diode is constantly turned on or blinked. In addition, when a plurality of light emitting diodes having different emission colors are used, the combined light decoration of the wax light emitting candle can be further improved by emitting these light emitting diodes simultaneously or in a predetermined order. it can.

  According to the first aspect of the present invention, the light of the combustion flame of the core material is introduced into the light sensor of the light emitting unit embedded in the candle body by the optical fiber embedded in the candle body along the combustible core material. This is detected, and based on the detection signal, the light emitting diode is caused to emit light in the candle body by a command from the light emitting circuit. As a result, healing effects, deodorizing effects, etc. as a general candle with a combustion flame can be obtained, and the candle body can be made to emit light from the inside by a light emitting diode, and the decorativeness of light can be exhibited in a composite manner. it can.

  In particular, according to the second aspect of the present invention, a plurality of light emitting diodes having different emission colors are used as the light emitting diode, and the light emitting circuit is configured to emit the plurality of light emitting diodes in a predetermined order. It is possible to further enhance the combined light decoration of the light emitting candle.

According to the invention described in claim 3, simultaneously with the molding of the candle body, before the light emitting diode is embedded in the candle body with the light emitting diode exposed from the top surface of the exterior casing, A diode thermal deterioration preventing layer made of a wax different from the wax for the candle body and having a thickness for burying the light emitting diode is laminated in advance.
By configuring in this way, the light emitting diode is covered in advance by a diode thermal deterioration prevention layer made of another wax smaller in amount than the molding amount of the candle body, so that the light generated from the light emitting diode in the candle body is halfway, Natural light intensity gradually decreases toward the outer peripheral surface of the candle body, centering on the light-emitting diode, without causing a local increase in luminous intensity due to the presence of the space formed inside the candle body. Attenuation can be produced. In addition, the amount of other wax used in the diode thermal deterioration prevention layer is less than the amount of wax used in the candle body and the cooling time of the wax is shortened. Can be suppressed.

  Furthermore, according to the invention described in claim 4, after a certain time has elapsed since the candle was ignited, the fragrance component diffuses and can soften the human mind, thereby producing an aromatherapy effect. it can.

  Hereinafter, embodiments of the present invention will be specifically described.

  1 and 2, reference numeral 10 denotes a wax light emitting candle (hereinafter referred to as a candle) according to Embodiment 1 of the present invention. The candle 10 is contained in a translucent container 11, a container 11, and is made of wax. The translucent candle body 12, the combustible core material 13 embedded in the candle body 12 with the length direction facing the length direction of the candle body 12, and the candle body 12 embedded along the core material 13. A combustible optical fiber 14 and a light emitting unit 15 that is embedded in the candle body 12 and detects the light of the combustion flame of the core member 13 introduced through the optical fiber 14 to light the candle body 12 are provided.

Hereinafter, these components will be specifically described.
As shown in FIGS. 1 and 2, the container 11 is a cup made of heat-resistant tempered glass whose surface is a ground glass surface, and has a circular opening shape.
The candle body 12 is a cloudy translucent aroma candle having a truncated cone shape that can be fitted into the container 11 and made of artificial wax obtained by kneading rose perfume with a predetermined blending amount in paraffin wax. In the specific production of the candle body 12, the light emitting unit 15 is placed at the center of the bottom surface of the mold having the same shape as the container 11, and only the tip portions of the core member 13 and the optical fiber 14 are placed. A molten wax (60 ° C.) containing rose perfume is poured from the liquid level (upper surface) of the wax to an exposed height, and this is cooled and demolded to obtain a candle body 12.
The core material 13 is made of flammable cotton yarn, and is positioned in a vertical state so that only the upper end protrudes from the center of the upper surface of the molded candle body 12 in the inner space of the mold when the candle body 12 is molded. Thereafter, the perfume-containing wax is slowly poured into the mold, and then cooled, so that the core 13 is disposed on the central axis of the candle body 12 and integrated.
The optical fiber 14 is formed by coating a plastic wire 14a having heat loss composed of a core and a grad having different refractive indexes of light with an opaque and flammable white coating paint 14b.

Next, the light emitting unit 15 will be described in detail with reference to FIGS. 3 and 4.
As shown in FIGS. 3 and 4, the light emitting unit 15 mainly includes an outer casing 16, three light emitting diodes 17 to 19 that shine the candle main body 12 from the inside, and the combustion of the core 13 through the optical fiber 14. The light sensor 20 detects the flame, the two button batteries (batteries) 21 serving as the power sources of the light emitting diodes 17 to 19, and the light emitting diodes 17 to 19 by the power of the button battery 21 based on the detection signal from the light sensor 20. And a circuit board 23 on which a light emitting circuit 22 for emitting light is formed.
The outer casing 16 is an opaque cylindrical container made of plastic with an open top surface, and is integrated with a cylindrical body portion 24 having a short height and a part of an opening portion on the lower surface of the body portion 24 via a resin hinge H. And a lid body 25 connected to each other. The lid 25 is opened and the button battery 21 is exchanged. A pair of hooking claws 26 for hooking the circuit board 23 to the opening of the outer casing 16 project from the opposing portion of the upper edge of the trunk portion 24. The circuit board 23 hooked to the outer casing 16 by the both hooking claws 26 constitutes a lid on the upper surface of the outer casing 16. At this time, the outer casing 16 is a sealed container with the upper and lower openings being closed.

Among the light emitting diodes 17 to 19, the light emitting diode 17 emits red light, and the light emitting diode 18 emits blue light. The light emitting diode 19 emits green light.
The circuit board 23 is obtained by forming a light emitting circuit 22 on an opaque circular plate material made of glass epoxy. The circuit board 23 is configured such that the light emitting circuit 22 is formed only on the back surface thereof, and the three light emitting diodes 17 to 19 are exposed on the front surface. Therefore, when the diode thermal deterioration preventing layer 27 is laminated on the upper surface of the circuit board 23 that is the upper surface of the outer casing 16, the glass epoxy circuit board 23 that is the upper plate of the outer casing 16 serves as a heat insulating material. As a result, when the later-described diode thermal deterioration prevention layer 27 is molded, the light emitting circuit 22 is not easily degraded by the heat of another wax poured into another molding die.
The light emitting circuit 22 includes a CPU 22a that causes the three light emitting diodes 17 to 19 to emit light in a predetermined order for a predetermined time by a detection signal from the optical sensor 20 including a photoelectric sensitivity element. The three light emitting diodes 17 to 19 are fixed on the upper surface of the circuit board 23 in a state of being separated in a triangular shape. An insertion hole at the lower end of the optical fiber 14 is formed at the center of the upper surface of the circuit board 23, and a short metal tube 28 is erected so as to cover the insertion hole. The lower end portion of the optical fiber 14 and the lower end portion of the core member 13 are inserted into the metal tube 28. By caulking the metal tube 28 in this state, the circuit board 23 in a state where the optical fiber 14 and the core member 13 are parallel to each other. Standing on the center of the.

A circular protective plate 29 made of a sponge sheet that protects the light emitting circuit 22 is attached to the back surface of the circuit board 23. A terminal hole is formed in the central portion of the protection plate 29 so as to penetrate the front and back surfaces and insert the negative electrode terminal 30 of the power supply system of the light emitting circuit 22.
Further, an L-shaped positive electrode terminal 32 extends downward from a part of the outer peripheral portion of the circuit board 23, and a negative electrode terminal 30 exposed through the terminal hole protrudes from the back surface of the protective plate 29. ing. The two button batteries 21 are sandwiched between the positive electrode terminal 32 and the negative electrode terminal 30 on the back side of the circuit board 23 using the elastic force of the positive electrode terminal 32.
The electric system of the light emitting unit 15 thus configured is inserted into the internal space from the opening on the upper surface of the outer casing 16, and in this state, the opposing portion of the outer edge portion of the circuit board 23 is hooked by the two hooking claws 26. By being stopped, the outer casing 16 is integrated.

On the upper surface of the outer casing 16 in which the light emitting unit 15 is incorporated, a diode thermal deterioration preventing layer 27 made of a different wax from the wax for producing the candle body 12 is laminated. Another wax does not contain a fragrance, and the diode thermal deterioration preventing layer 27 has the same diameter as that of the circuit board 23 in a plan view and has a thickness to bury the light emitting diodes 17 to 19. It is a circular plate material that is 1 to 3 mm thicker than the 19 length.
In the production of the diode thermal deterioration preventing layer 27, the light emitting unit 15 is fitted into another dedicated mold while the light emitting diodes 17 to 19 are arranged in the molding space, and another wax melted in this state is poured into the mold. After that, it is cooled and demolded. Thereby, the diode thermal deterioration preventing layer 27 in which the light emitting diodes 17 to 19 are embedded is formed on the upper surface of the outer casing 16.
Thereafter, the candle body 12 in which the light emitting unit 15 is embedded is inserted into the container 11 and fixed to the bottom plate of the container 11 with an adhesive.

Next, with reference to FIGS. 1-4, the usage method of the candle 10 which concerns on Example 1 of this invention is demonstrated.
When using a candle, the core material 13 is lit using a match or the like. Thereby, combustion light (ignition light) enters the inside of the optical fiber 14 from the tip, and the light passes through the optical fiber 14 to the optical sensor 20 of the light emitting unit 15 embedded in the lower part of the candle body 12. Led. Based on this, the light emitting circuit 22 is closed, and the red light emitting diode 17, the blue light emitting diode 18, and the green light emitting diode 19 are caused to emit light for a predetermined time in a predetermined order. Thereafter, the light emission of the light emitting diodes 17 to 19 in this order is repeated. As a result, a healing effect, a deodorizing effect, etc. as a general candle 10 accompanied by a combustion flame can be obtained, and the candle body 12 is caused to emit light from the inside by the light emitting diodes 17 to 19 and the light is made of ground glass. When viewed through 11, the decorativeness of light can be exhibited in combination. For example, in recent years, with the Western proverb that “An angel dwells in a small fire”, which is becoming customary in the candle 10 service for wedding receptions, The wedding ritual of “raising the happiness of two people together with white smoke” can be performed without any problems. Further, the optical fiber 14 gradually disappears as the core material 13 burns away. Thereby, the combustion light of the core material 13 can be always guided to the optical sensor 20.

Further, as the light emitting diodes 17 to 19, three kinds of light emitting diodes of red, blue, and green emitting three primary colors having different emission colors are used, and these light emitting diodes 17 to 19 are arranged in a predetermined order by the light emitting circuit 22. In addition, since it is configured to emit light only for a predetermined time, it is possible to emit light in various colors and to further enhance the composite light decoration of the wax-emitting candle 10.
Further, after a certain time has elapsed since the candle 10 was ignited, the fragrance component contained in the candle body 12 diverges. Thereby, a person's heart can be softened and an aromatherapy effect can be produced.

Further, since the light emitting unit 15 houses an electric system (such as the optical sensor 20, the button battery 21 and the circuit board 23) in the outer casing 16, the light emitting unit 15 is attached to the candle main body 12 at the same time as the candle main body 12 is molded. When embedding, deterioration of the electrical system of the light emitting unit 15 due to the heat of the wax can be prevented.
Furthermore, here, before embedding the light emitting unit 15 in the candle body 12, the thickness of the upper surface of the outer casing 16 is made of another wax different from the candle body wax and the light emitting diodes 17 to 19 are buried. A diode thermal deterioration preventing layer 27 having the above is laminated in advance. That is, the light emitting diodes 17 to 19 are covered in advance with the diode thermal deterioration preventing layer 27 made of another wax whose amount is smaller than the molding amount of the candle body 12. Therefore, the light generated from the light emitting diodes 17 to 19 in the candle body 12 does not cause a local increase in luminous intensity due to the presence of the space formed inside the candle body 12 in the middle. With the light emitting diodes 17 to 19 as the center, it is possible to produce natural light attenuation in which the light intensity gradually decreases toward the outer peripheral surface of the candle body 12. In addition, the amount of another wax used in the diode thermal deterioration prevention layer 27 is smaller than the amount of wax used in the candle body 12 and the cooling time of the wax is shortened. Thermal degradation can be suppressed.
