Description

[Technical Field]

[0001] The present invention relates to an electronic incense stick, and more particularly to a technology for more realistically simulating the flame of an incense stick. [Background technology]

[0002] Conventionally, from the viewpoint of fire prevention, so-called electronic incense has been used, which simulates the state of a lit incense stick placed in an incense holder (hereinafter also referred to as simulated combustion). However, in most cases, the tip of the incense stick fixed to the incense holder glows red using optical fiber or LED. Therefore, even if the incense stick is simulated to be burning, the length of the incense stick does not shorten, so the user cannot get the feeling that he or she is actually burning incense. Also, even though the incense uses electricity, there were concerns about the electronic circuits continuing to operate due to fire prevention reasons. Therefore, there has been a demand for electronic incense that does not use fire but allows the user to feel the sensation of using incense and in which the electronic circuitry is shut down without the user having to operate it.

[0003] Various technologies have been proposed to address these problems. For example, an electronic incense stick (see Patent Document 1) has been proposed and is known as a known technology, which can give the impression that actual incense sticks used in Buddhist altars are burning. More specifically, the surface of the tip of the incense stick is formed into a number of uneven reflective surfaces, and a control unit is provided that controls the voltage output from the power supply unit so that it is applied with cyclically increasing and decreasing strength. The light emitted by the applied voltage is reflected by the uneven reflective surfaces, resulting in a fluctuating light emission. However, there is no description of a technique for simulating the shortening of incense sticks over time, and the above problem is not solved. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-229069 Summary of the Invention [Problem to be solved by the invention]

[0005] To provide an electronic incense stick that can simulate the burning and shortening of an incense stick, thereby providing a feeling of using incense sticks and eliminating anxiety about the electronic circuit continuing to operate, in view of the above problems. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present invention provides an electronic incense stick comprising a plurality of LEDs, a control unit, a rod-shaped substrate, and a translucent exterior covering them, the plurality of LEDs and the control unit being arranged on the substrate, the LEDs being capable of emitting at least red light, the lighting of the LEDs being controlled by the control unit, the control unit performing a simulated combustion by repeatedly lighting and extinguishing the LEDs in order starting from the top, and when the bottom LED lights and goes out, or after a specified time has passed, all LEDs are turned off and the simulated combustion ends.

[0007] Furthermore, the present invention employs a means in which the specified time is changeable.

[0008] Furthermore, the present invention employs a means for making it possible to change the time for turning on and off the LED.

[0009] Furthermore, the present invention employs a means in which the LED can emit light by mixing a plurality of colors and changes the color tone depending on the time elapsed since lighting began.

[0010] Furthermore, the present invention employs a means in which the LEDs are capable of emitting a mixture of red, blue, and green colors, and the control unit sequentially lights up the LEDs from the top in red to indicate combustion, and also lights up the red, blue, and green LEDs in white to indicate ash after combustion.

[0011] Furthermore, the present invention employs a means for starting simulated combustion by having a switch unit and a battery and operating the switch unit.

[0012] Furthermore, the present invention employs a method of placing the electronic incense horizontally in a container (such as an incense burner), connecting the wiring from the bottom of the electronic incense to a switch section in the container and a power source, and turning on the switch to start simulated combustion.

[0013] Furthermore, the present invention employs a means for providing a plug portion at the bottom of the electronic incense, providing a socket corresponding to the plug on the surface of a container (such as an incense burner), providing a power source connected to the socket within the container, and supplying power to the electronic incense by inserting the plug into the socket, thereby starting simulated combustion. [Effects of the Invention]

[0014] According to the present invention, even with electronic incense, it is possible to see the incense burning and shortening, so that the user can feel the sensation of burning incense and eliminate anxiety about the electronic circuit continuing to operate, thereby improving the user's satisfaction. Furthermore, since the present invention does not involve actual combustion, there is no risk or concern of embers remaining or fire starting, and since no smoke is produced, there is no harm from soot, such as staining walls and wallpaper or resin adhering to the incense burner, and there are no physical effects due to smoke allergies. Furthermore, according to the present invention, since no combustion ash is generated, the room is not soiled by scattering ash, and disposal of the ash is not required, so cleaning work is not required.

[0018] The electronic incense stick 1 uses light from an LED (light emitting diode) to simulate the burning fire of an incense stick, and serves as a substitute for an incense stick. The electronic incense stick 1 comprises a plurality of LEDs 20, a control unit 31, a substrate 30, and a translucent exterior 50 that covers them. The LED is turned on and off by the control unit. It also has a switch and battery, and simulated combustion can be started by operating the switch.

[0019] The LED 20 is an element that emits light when a current flows through it. As shown in Fig. 4, one side (anode side) is connected to a power supply 35, and the other side (cathode side) is connected to a terminal of the control unit 31 via a resistor 32. The resistor 32 limits the current to the LED 20 to a certain amount. By using the LED 20 that emits red light, the red burning color of incense can be imitated. As shown in FIG. 2, by arranging a plurality of LEDs 20 on a substrate 30 and changing the LEDs that emit light in sequence depending on the elapsed time of burning, it is possible to express the appearance of an incense stick getting shorter as it burns. The entire electronic incense stick 1 needs to have roughly the same dimensions as an incense stick, so it can be thought of as being about 20 cm long and 2 mm thick, for example. LEDs come in two types: cylindrical, called bullet-type, and leadless, called chip-type. Most bullet-type LEDs are about 5 mm in diameter, and are not suitable for this example. Therefore, this example will explain an example of a chip-type LED. The chip type includes mini LEDs and micro LEDs, which are about 1 mm wide. Mini LEDs and micro LEDs are designed so that the chip is soldered directly to the substrate 30. As shown in FIG. 2, many LEDs 20 can be arranged in a small area. LEDs can be classified functionally into those that emit a single color and those that can emit multiple colors. If you only need to emit red light, an LED that emits a single red light is appropriate. If you want to change the color during combustion or express ash after combustion, you will need to prepare LEDs of multiple colors. However, when arranging LEDs on a substrate 30 with a diameter of 2 mm, it can be difficult to arrange multiple types of LEDs. In such cases, LEDs with multiple colors mounted on a single chip are used. For example, two-color LEDs 22 and three-color LEDs 23. Two-color LEDs 22 and three-color LEDs 23 have similar dimensions to single-color LEDs, making them easier to mount. In the example of Figure 2, approximately 30 to 50 LEDs 20 are arranged. For example, if it is desired to emit red and orange light, a bicolor LED 22 having a red LED 21 and a green LED 25 on one chip is used. To emit red light, only the red LED 21 is turned on, and to emit orange light, both the bicolor LED 22 and the green LED 25 are turned on. The green LED 25 emits about half the amount of light emitted by the bicolor LED 22. By changing the amount of light emitted by the two LEDs 20, it is possible to gradually change the color, for example, from red to orange. Basically, all colors can be emitted by using the red LED 21, blue LED 24, and green LED 25 as the three-color LED 23. For example, if red and gray are to be emitted, only the red LED 21 is made to emit light when red is to be emitted, and the red LED 21, blue LED 24, and green LED 25 are made to emit light at similarly weak levels when gray is to be emitted. Moreover, when emitting green light, only the green LED 25 needs to be turned on.

[0020] The control unit 31 is a part that controls the entire electronic incense stick 1. Since the electronic incense stick 1 performs relatively complex control, it is suitable to control it by a program using a microcomputer. The control unit 31 comprises a central processing unit which is a microcomputer, a non-volatile memory, a temporary storage memory, and various drivers. The control unit 31 has terminals connected to the respective LEDs 20. Each LED 20 is connected to a terminal via a resistor 32. The number of terminals corresponds to the number of LEDs 20. The electronic incense stick 1 has a switch section 12, and by turning the switch section 12 on / off, the entire electronic incense stick 1 can be started or stopped, and by turning the switch section 12 on / off, the operating state of the electronic incense stick 1 can be changed. Also, to indicate the operating state, the LED 20 corresponding to the mode display unit 11 is controlled to be turned on, off, or flashing. Basically, when this LED 20 is turned on, it indicates that the electronic incense stick 1 is in an operating state, and when it is turned off, it indicates that it is in a stopped state. Also, flashing or the like indicates other operating states. The control unit 31 is equipped with drivers for driving the LEDs 20, the number of which corresponds to the number of LEDs 20 to be controlled. As shown in the control unit in Fig. 4, the driver consists of a buffer 34 and a transistor 33. When the LEDs 20 are to be made to emit light, the buffer 34 is activated, turning on the transistor 33, causing current to flow from the LEDs 20, causing the LEDs 20 to emit light. When turning on or off the LEDs 20 individually or changing the color of the multicolor LEDs, the corresponding drivers in the control unit 31 are controlled.

[0021] The substrate 30 is a base on which the LEDs 20, the control unit 31, etc. are mounted. A plurality of LEDs 20 and the control unit 31 are arranged on the substrate 30. Also arranged are wires that connect the LEDs and the control unit, wires that supply power to the LEDs 20, etc. Since a large number of wires are arranged to control many LEDs 20, it is preferable to use a multi-layer substrate. Furthermore, since the LED 20 is likely to reach high temperatures, a material with high thermal conductivity such as alumina is appropriate. The substrate 30 is rod-shaped and is disposed over almost the entire length of the electronic incense stick 1. The switch unit 12 is disposed at the bottom. The LED 20 and control unit 31 are disposed on one side of the substrate 30, and the other side is fixed to the exterior casing 50. By being fixed to the exterior casing 50, heat from the LED 20 can be transferred to the exterior casing 50 and dissipated. The battery 40 may also be mounted on the substrate 30 .

[0022] The exterior casing 50 is shaped to completely cover the electronic incense stick 1. It is translucent and diffuses the light emitted by the LEDs 20 while radiating it outward. The exterior casing 50 has partitions 51 arranged between each of the LEDs 20. Without the partitions 51, the light from the LEDs 20 would be radiated widely upward and downward, making it unclear where the burning part is. The partitions 51 separate and block the LEDs 20, making it possible to clearly identify the positions of the emitting LEDs 20. The partitions 51 may have sufficient light-blocking properties, or may have a light-diffusing effect that allows some light to leak upward and downward. The lower part of the exterior 50 has a mode display section 11, which indicates the operating mode of the electronic incense stick 1 by turning on or off an internal LED 20, etc.

[0023] 1 to 4 show an embodiment using only red LEDs 21. FIG. As shown in FIG. 1(a), the shape is modeled after an incense stick, and the exterior 50 is translucent light green, with part of it turning red due to the light emitted by the internal red LED 21, imitating the flame of an incense stick. A push button switch section 12 is arranged at the bottom, and a mode display section 11 that indicates the operating state is located nearby. Approximately 80% of the top is an LED display unit 10. By pressing and holding the switch 12, the electronic incense 1 is turned on, and the red LED 21 at the top lights up red. After confirming that the electronic incense 1 is lit, the user places it in the incense holder 71 of a container 70 such as an incense burner, as shown in FIG. 1(b), in the same way as placing regular incense. At this time, the incense holder 71 is filled with incense ash, and the electronic incense 1 can be placed by sticking it into the incense ash, as in the conventional case. Alternatively, as shown in FIG. 5(b), the incense holder 71 may have a base structure molded from resin or the like, and the incense holder 71 may have a socket 72 into which the electronic incense 1 can be inserted, and the electronic incense 1 may be inserted and placed upright in the socket 72. As shown in Fig. 3(a), the topmost part of the electronic incense stick 1 first emits red light 26. Inside, the topmost red LED 21 emits light. The LEDs are separated by a partition 51, so only the topmost part appears to be lit. After a certain time has passed, the top red light 26 goes out and the part below it turns red. Inside, the second red LED 21 from the top is emitting light. Because it is separated by a partition 51, only the second from the top appears to be lit. This makes it appear less strange as if incense is burning. In other words, the control unit performs a simulated combustion by repeatedly turning on and off the LEDs in order starting from the top, and when the bottom LED turns on and off, or after a specified time has elapsed, all LEDs are turned off and the simulated combustion ends. These actions make it appear as if the red light of the burning incense is gradually moving from top to bottom. When the red LED 21 reaches the LED 20 at the bottom, after a certain time, all the LEDs 20 are turned off and the electronic incense 1 stops. For example, if the burning time of incense is about 20 minutes, the behavior of an incense stick can be roughly imitated by setting the light emission time of one LED 20 to about 30 seconds to 1 minute.

[0024] The circuit configuration is as shown in Figure 4(a). The control unit 31 is a microcomputer with an LED driver. All of the LEDs 20 are red LEDs 21, with L1 to L50 representing incense sticks, and D indicating the mode. One side of the LED 20 is connected to a power supply, and the other side of the LED 20 is connected to a current-limiting resistor 32, which is then connected to a terminal of the control unit 31. In the control unit 31, a buffer 34 connected to the transistor 33 and the base of the transistor 33 is turned on, causing a current to flow and causing the LED 20 to emit light. Control can be performed individually for each of the LEDs 20, allowing for delicate control that mimics incense sticks.

[0025] As another example of control, combustion can be stopped midway or the combustion speed can be increased. When it is known that the time for using the incense is short, the electronic incense 1 can be used efficiently by stopping the incense midway or simulating a state in which the burning speed is increased, and after the time for use is up, the electronic incense 1 automatically stops without any stopping operation, which is convenient. There are various methods for changing the state of the electronic incense 1 in this way, but in this embodiment, an example of changing the setting at the switch unit 12 will be described. If the switch unit 12 were a single push switch, it would simply only be possible to turn the electronic incense 1 on and off. Therefore, turning the electronic incense 1 on and off is done by pressing and holding the switch. For example, pressing and holding the switch for three seconds or more turns the electronic incense 1 on or off. In contrast, it is possible to cycle through multiple modes by pressing the button for a short time. For example, in the case of cycling through four modes, as shown in Figure 4(b), it is possible to change whether the incense stick burns completely or stops at half its full length, and whether the burning speed is normal or fast. The mode can be confirmed by checking the lighting state of the mode display section 11. There are four lighting states, for example, lighting, blinking once, blinking twice, and blinking three times. In this way, the specified time can be changed, and the time for turning on and off the LED can also be changed, allowing the user to easily change the state.

[0026] Another possible form of electronic incense 1 is a horizontal type. Depending on the sect, incense sticks may be placed horizontally. As shown in Figure 5(a), the electronic incense stick 1 is placed horizontally on an incense holder 71 of a container 70 such as an incense burner. The electronic incense is placed horizontally in the container, and the wiring from the bottom of the electronic incense is connected to the switch inside the container and the power source, and the simulated combustion begins by turning on the switch. The electronic incense can be a single stick or a set number of sticks bundled together. A hole is drilled at the bottom end of the electronic incense stick 1, and the external wiring 60 is pulled out and connected to the battery 40 and switch unit 12 inside the container 70. By adopting such a configuration, the user can feel the flame of the incense burning gradually by operating the switch portion 12 of the container 70.

[0027] As shown in FIG. 5(b), a configuration is also conceivable in which the electronic incense 1 itself does not have a power source, but is instead powered by a battery 40 in a container 70. A plug portion 13 is disposed at the bottom of the electronic incense stick 1. The plug portion 13 comprises a ground terminal 61 and a power terminal 62. A socket portion 72 is disposed in an incense holder portion 71 of the container 70. The socket portion 72 is inserted into a through-hole in the incense holder portion 71 and is supported by a support portion 75. The socket portion 72 comprises a ground contact 73 and a power contact 74. The electronic incense stick 1 is inserted into the incense stick holder 71. In other words, the plug portion 13 of the electronic incense stick 1 is attached to the socket portion 72. The user simply inserts the electronic incense stick 1 into the socket portion 72 of the incense stick holder 71 and stands it up, just like regular incense sticks, so there is little sense of discomfort. By attaching the plug portion 13 to the socket portion 72, the ground terminal 61 and the ground contact 73 are connected, and the power terminal 62 and the power contact 74 are connected, so that power is supplied to the electronic incense stick 1. When power is supplied to the electronic incense stick 1, the control unit 31 is activated and immediately starts lighting up the LED. This is convenient because the user does not need to light the incense sticks themselves, and the fire will light automatically. When the use of the electronic incense 1 is completed, the electronic incense 1 can be pulled out from the container 70 to return it to its original state and can be used again and again.

[0028] In the above embodiment, an example in which only the red LED 21 is used has been described, but by controlling the emission of a plurality of colors, it is possible to more realistically simulate incense. There are two ways to emit light of multiple colors: one is to prepare an LED for each color and place it on the substrate 30, and the other is to place LEDs of multiple colors mounted on a single chip on the substrate 30. Either method is acceptable. In this embodiment, LEDs are arranged on an extremely thin substrate 30, and therefore LEDs of multiple colors are mounted on one chip.

[0029] One of the benefits of being able to emit multiple colors is that the color can be gradually changed by changing the amount of light emitted. In other words, LEDs can emit a mixture of multiple colors, and the color can be changed depending on the time elapsed since the LED was first turned on. A case will be described in which the color of the incense changes over time from red light 26 to orange light 27. This type of operation is convenient because the user can sense the amount of time that has passed from the change in color. FIG. 6(a) shows a circuit diagram for a bicolor LED 22. A red LED 21 and a green LED 25 are mounted on a single chip. Even when multiple LEDs are mounted, the dimensions of the chip package are approximately the same. Within the bicolor LED 22 chip, the anode terminals of the red LED 21 and the green LED 25 are connected, and the cathode terminals are separate, with three wires drawn from the bicolor LED 22. The anode side is connected to a power supply, and the cathode side is connected to a terminal of the control unit 31 via a resistor. The LED control will be explained with reference to Figure 7(a). When the electronic incense stick 1 is stopped, all LEDs are off. When it is started, the red LED 21 of the two-color LEDs 22 at the top first lights up (L1). After a certain time has passed, the L1 of the two-color LEDs 22 at the top goes out and L2 lights up. The red LED 21 lights up at 100%, and the green LED 25 lights up slightly at about 12%. With the red light fully lit and the green light slightly lit, the overall result is a red light 26 that is slightly close to orange light 27. Next, after a certain time has passed, L2 turns off and L3 turns on. The red LED 21 is fully lit at 100%, and the green LED 25 is lit at 25%, which is about 1 / 4 of the red LED 21. As the amount of orange light 27 increases relative to the red light 26, the overall light emission becomes red, close to orange. Next, after a certain time has passed, L3 goes out and L4 lights up. The red LED 21 lights up completely, and the green LED 25 lights up at 50%, which is about half the brightness of the red LED 21. With a red:green ratio of 2:1, the light emits a roughly orange color 27. In this way, the color of the incense flame changes to represent the passage of time. Also, by periodically changing the color between red light 26 and orange light 27, it is possible to represent something closer to an actual flame.

[0030] Basically, all colors can be displayed by using three-color LEDs 23: a red LED 21, a blue LED 24, and a green LED 25. The LEDs can be chips or three individual types of LEDs, but we will explain the chip type, which can be arranged compactly, just like the two-color LEDs. As an example of color representation, the fire and ashes of an incense stick can be represented. The fire can be represented by red light 26, and the ashes can be represented by dark white light 28. In other words, the LEDs can emit light by mixing red, blue, and green colors, and the control unit can sequentially light up the LEDs from the top of the electronic incense stick in red to represent burning, and then light up the LEDs in red, blue, and green to represent white ashes after burning. In another example, the colors of the materials used in incense, such as green and dark blue, can also be expressed. In this way, by using the three-color LED 23, it is possible to further enhance the sense of realism. FIG. 6(b) shows a circuit diagram for a three-color LED 23. A red LED 21, a blue LED 24, and a green LED 25 are mounted on one chip. Even when multiple LEDs are mounted, the dimensions of the chip package are approximately the same. Within the three-color LED 23 chip, the anode terminals of the red LED 21, the blue LED 24, and the green LED 25 are connected, while the cathode terminals are separate, with four wires drawn from the two-color LED 22. The anode side is connected to a power supply, and the cathode side is connected to a terminal of the control unit 31 via a resistor. The control of the LED will be explained with reference to Figure 7(b). The LED light is used to represent the flame and ashes of an incense stick. When the electronic incense stick 1 is off, all LEDs are off. When it is started, the red LED 21 of the three-color LED 23 at the top first lights up (L1). After a certain time has passed, the red LED 21 of the three-color LED 23 at the top, L1, continues to light up, and the blue LED 24 and green LED 25 light up. By lighting up the red, green, and blue LEDs, the overall color becomes white, simulating ash. The second LED from the top, L2, lights up. The red LED 21 lights up, while the blue LED 24 and green LED 25 remain off. The top L1 emits white light 28 and the top L2 emits red light 26, so that the appearance represents a fire with ash on top. Next, after a certain time has passed, the blue LED 24 and green LED 25 of L2 and the red LED 21 of L3 are turned on. The red LED 21, blue LED 24, and green LED 25 of L1 and L2 are turned on, resulting in white light emission 28, and L3 is turned on in red light 26. In this way, the red light 26 gradually decreases and the white light 28 increases, which expresses the incense burning and the ashes increasing.

[0031] The green color of the incense can also be expressed using green LED25. Referring to Figure 7(c), we will explain an example of using LEDs to represent the flame, ash, and green color of the incense stick. When it starts up, the red LED 21 at the top L1 lights up, just like in Figure 7(b), but in the part where the incense is not yet lit, the green LED 25 emits green light 29, representing the green color of the incense. Therefore, all of the green LEDs 25 from L2 to L50 are lit. By reducing the green light 29 at regular intervals, it is possible to express the burning of incense.

[0032] In the electronic incense 1 according to the present invention having the above-described configuration, the specific configuration of the battery 40 is not particularly limited, and a battery 40 suitable for each embodiment of the electronic incense 1 may be selected and adopted. For example, all embodiments of the electronic incense 1 may be configured to have a dry cell battery, button cell battery, rechargeable battery, etc. installed inside, or in the case of a horizontally placed electronic incense 1, it is also preferable to have a dry cell battery or rechargeable battery built into the container 70, or to have a power plug and cord that can be connected to a household power outlet.

[0033] Thus, according to the present invention, even with electronic incense, it is possible to simulate the appearance of an incense stick burning and shortening, so that the user can get a sense of the actual act of burning incense, and it is possible to eliminate anxiety about the electronic circuit continuing to operate, thereby improving user satisfaction.

[0034] Furthermore, since the simulated burning time of the incense can be changed, the use of the electronic incense can be automatically terminated even if it is in the middle of use after the required time has elapsed. Furthermore, since the simulated burning speed of the incense can be changed, it is possible to use up the electronic incense within the required time. Furthermore, the color of the simulated combustion fire can be changed over time, which is convenient as it allows the elapsed time to be judged from the color of the fire. Furthermore, in addition to the color of the flame, the color of the ash can also be simulated, allowing for a more realistic imitation of incense.

[0035] Furthermore, it is battery-powered, can be started and stopped with a switch, and can be placed upright in an incense holder or horizontally like regular incense, so that the user can have the feeling of actually burning incense, and it can be used by various sects. Furthermore, by configuring the electronic incense to have a plug on the side of the electronic incense and a socket on the side of the container, the electronic incense can be operated using the power source on the side of the container even if there is no power source on the side of the electronic incense, making battery management easier.
