Description

  The present invention is a light emitting device such as a penlight, a stick light, or a rod-shaped light that is mainly used by participants such as spectators in various events and concerts (collectively referred to herein as “concerts”). The present invention relates to an instrument (referred to herein simply as “event light-emitting instrument”).

  Conventionally, many light emitting devices for events use a dry cell as a power source. This is because if a dry cell is used as the power source, a considerable amount of power can be secured. When using dry batteries, it is also possible to support high-power, high-brightness LEDs (bright light is obtained) that consumes more power in LED / LED lights / LED bulbs (hereinafter simply referred to as “LEDs”). Become. In addition, in order to make it easy for users to use and hold the event light-emitting device in their hands for a long time, among the dry cells, the light-emitting device for events is powered by a relatively light and small AAA battery. There are many.

  For example, when three unused AAA batteries are used, even if a light emitting device for events equipped with four 1.0 W LEDs is continuously lit at the required brightness, it emits light for about 10 hours. It is possible to make it. In order to obtain light emission with higher brightness, four AAA batteries may be used (Patent Document 1).

  On the other hand, as one of the features of recent events, for example, in a concert of an idol group in which a plurality of members have their respective image colors, the concert participants can view the light emitting devices for the event according to the progress of the stage. There are things such as cheering by emitting colors in color and cheering, and emitting light for event lighting with a specific color when playing a specific song. Therefore, there is a demand for a light emitting device for events that can obtain a large number of luminescent colors with a single one.

  In order to meet such demands, red LEDs, green LEDs, and blue LEDs (RGB LEDs) are used as light sources, and the colors emitted from these are blended, mixed, and adjusted (hereinafter also referred to as “toning”). ) To obtain a desired emission color. This utilizes the principle of the so-called three primary colors of light (Grassman's law, such as color trichromaticity). According to this technology, a large number of emission colors can be obtained (can be sequentially turned on with different emission colors) by one event light emitting device (for example, one penlight) (Patent Documents 2 and 3).

  Toning with such RGB LEDs requires stable power supply. This is based on the fact that the amount of power required for toning differs between RGB, so that if the supplied power is insufficient, the color mixture balance is lost and a desired emission color cannot be obtained. Therefore, in terms of obtaining a desired light emission color in addition to the light emission duration and the like, for example, a dry battery that can supply a stable power while securing a certain amount of power as compared with a button type (type) battery with a small amount of power storage. Is preferred.

  Recently, however, event participants (users of event light-emitting devices) throw event light-emitting devices during the event, which hits the equipment in the venue and damages the equipment. For example, although it is relatively light among dry batteries, in the case of an event light emitting device using three AAA type dry batteries, the weight of the event light emitting device as a whole is about 100 g. Therefore, when an excited event participant throws such a light emitting device for an event, not only the equipment is damaged, but there is a possibility that the person may be seriously injured. This risk is further increased if the event participant has multiple penlights and participates in the event. In addition, depending on the situation of the event or the like, it must be assumed that a plurality of persons throw an event light-emitting device.

  In view of such safety considerations, event organizers have recently put restrictions on the weight of event light emitting devices, such as the weight of usable event light emitting devices. Regulations such as setting an upper limit are made. In particular, as an embodiment of weight restrictions, there have been some events that prohibit light emitting devices for events that use dry batteries.

  Furthermore, if the light from the light emitting device for the event is too bright, it will interfere with the progress of the event, or if the event is photographed to make a video such as a DVD, the light will cause a failure. In order to prevent the emission of light, there have also been events that prohibit light emitting devices for events that use dry batteries.

  In an event in which these restrictions are made, event participants cannot use event light-emitting devices that use dry batteries as a power source, but use event light-emitting devices that use button-type batteries as a power source.

  In this way, recently, the light emitting devices for events that are permitted to be used are different for each event or event venue.

  However, for example, in an idol-related event, an event participant often participates in other events in a day (goes around multiple event venues), and the use of penlights using dry batteries is permitted. In many cases, it participates in both of these events. In such a case, the event participant needs to possess at least two types (two) of the event light-emitting devices, that is, the event light-emitting device using dry batteries and the event light-emitting device using button-type batteries.

  In addition, each participant often holds a plurality of event light-emitting devices in one event, and a participant who participates in such an event multiple times in a day is not able to use an event light-emitting device that uses dry batteries. Carry multiple light emitting devices for events (equipped with dry batteries) for use in events that are allowed to be used, and multiple light emitting devices for events (equipped with button batteries) for use in events where this is not permitted A situation has arisen in which it must be carried.

  In such a situation, it would be extremely convenient for event participants (users of event light-emitting devices) to use the event light-emitting device as a power source for both dry batteries and button-type batteries. On the other hand, even a light emitting device for an event equipped with a high-output, high-brightness LED can meet the needs of event organizers who wish to prohibit bright light emission if the brightness is naturally limited.

  In a field different from the event light-emitting device, for example, a technology for changing the size of dry cells has been proposed (for example, Patent Document 4). The purpose of this is to ensure that the amount of electricity that can be used in an emergency is not fixed, such as a flashlight, and that it can be used in an emergency. Is assumed.

  On the other hand, the button-type battery and the dry battery have not only greatly different standards but also greatly different power capacities. For example, in portable lighting fixtures and the like, a battery powered by a dry battery and a battery powered by a button-type battery may be configured as separate appliances (Patent Document 5, especially FIGS. 1 and 2). In addition, the portable lighting fixture is not only different in function and the like from the light emitting device for events, and Document 5 cannot exchange these batteries (dry batteries and button batteries) in one device.

  Conventionally, substitution and replacement between a button-type battery and a dry battery are not considered (conventionally, there is no demand for them), and a technique related to an event light-emitting device as described above has not been proposed.

JP 2014-175100 A JP 2000-90702 A JP2013-235838A JP 10-144273 A JP-A-11-7802

  The light emitting device for events powered by dry batteries and the light emitting device for events powered by button-type batteries have been treated as separate items depending on the degree of light emission (brightness), the event used, and the application. Yes.

  In view of the above-mentioned problems caused under such circumstances, the present invention provides a system used for an event light-emitting device for enabling use of either a dry battery or a button-type battery as a power source, its members, and An object of the present invention is to provide a light emitting device for events using these.

  Embodiments according to the present invention will be specifically described below with reference to the drawings. In the drawings and the description of the embodiments, the same reference numerals are used for the same members.

  The power source (battery) of the event light-emitting device is disposed inside the grip (not only in the present invention but generally). The grip portion needs to have a size and shape (usually substantially cylindrical) that are easy for a user of the event light-emitting device to grip. In addition, as described above, recently, restrictions are often placed on the weight and size of event light emitting devices that can be used in events. From these points, there are restrictions on the size and shape of the grip portion of the light emitting device for events, and the space in which a battery or the like can be mounted is limited.

  The present invention relates to a type of battery (dry cell, button) that uses a limited space in an event light-emitting device in an event light-emitting device that has conventionally been handled separately for a dry cell and a button-type battery. The problem is solved by configuring the battery to be changeable.

  The present invention can also be applied to a single-color event light-emitting device having one LED as a light source. In the first embodiment, there are three high-power and high-intensity 1.0 W LEDs (RGB LEDs) as a light source. A case where a button-type battery can also be used in a light emitting device for an event, which is basically provided with a space for storing a dry battery inside the gripping part and using the dry battery as a power source, will be described.

(Embodiment 1)
With reference to FIG.1 and FIG.2, in this embodiment, in the inside of the holding part 2 of the light-emitting instrument 1 for events, the space in which three AAA type batteries are accommodated as a main body battery accommodating part, ie, a main body dry battery A storage unit 3 is provided. When using a dry battery, three AAA batteries (alkaline battery, rechargeable battery, etc.) are attached to the main battery storage unit 3 and used as a power source. In this case, when the power input switch 4 is turned on, the LEDs (not shown, illuminate the cover member 5, which are covered by the cover member 5 in the drawing) provided above the grip portion 2 are each 1.0 W. It can emit light.

  In the present embodiment, a central storage unit 6 is provided at the center back of the main body dry cell storage unit 3, and a left storage unit 7 and a right storage unit 8 are provided on the left and right of the front side, respectively, so that a single dry cell can be stored. ing. Moreover, it is comprised so that the upper side of the center accommodating part 6 and the left side accommodating part 7, and the lower side of the right side accommodating part 8 may become a positive electrode side (positive electrode).

  The grip unit 2 is provided with an operation unit such as an operation switch 9 for operating a light emission color, in addition to a power input switch 4 for operating power on / off. In addition, a control unit that controls power on / off and emission color according to commands from these operation units can be provided inside the gripping unit (for example, above the main battery storage unit 3 and below the LED). .

  As shown in FIG. 3, after the dry battery 10 (the dry battery attached to the central storage 6 is not shown) is attached to the main battery storage 3, the opening 11 of the main battery storage is shown in FIG. The lid 12 is fitted in (a place where the dry battery is taken in and out) and fixed by the lower cap 13. The lid 12 and the lower cap 13 constitute part of the grip portion 2.

  5 to 7 show an example of a power supply changer according to the present invention. The power changer 14 has an opening 15 for inserting and removing a button-type battery, and includes change button-type battery storages 16 and 17 for attaching the button-type battery therein. In the example of the change button-type battery storage unit of this embodiment, the LR44-type button battery (1.5 V) is configured to be stored in three pieces in the upper stage 16 and three in the lower stage 17 (total of six pieces). ing. The upper stage 16 is configured such that the upper side is on the positive side and the lower stage 17 is on the negative side, and the upper voltage total 4.5 V and the lower voltage total 4.5 V are connected in parallel.

  The power supply changer has an outer shape and a size that can be attached to the main body dry cell storage unit 3, and is configured to be detachable from the main unit dry cell storage unit 3.

  It is possible to avoid an increase in weight by using a resin or the like as the material of the entire power supply changer.

  An electrode contact portion is provided on the outer upper portion and the outer lower portion of the power supply changer so that power can be supplied by being electrically connected to the positive electrode and negative electrode of the main battery storage unit. In the present embodiment, a positive electrode contact portion 18 that comes into contact with the positive electrode side 20 (FIG. 2) on the upper side of the left side storage portion of the main body battery storage portion 3 is provided on the outer upper portion of the power supply changer, and is located below the central storage portion of the main body battery storage portion. The negative electrode contact part 19 which contacts the negative electrode side 21 (FIG. 1) of the side is provided in the outer lower part of the power supply changer. Thereby, it is possible to supply power from the button-type battery attached to the power changer.

  When the button-type battery is used as the power source, the AAA dry battery 10 is removed from the main body dry battery storage 3 of the grip 2. Then, six button-type batteries 22 are stored in the button-type battery storage units 16 and 17 for change of the power supply changer 14 (see FIG. 7), and the power supply changer 14 is attached to the main battery storage unit 3 for use. . FIG. 8A shows a state before the power supply changer 14 is attached to the main battery dry cell storage unit 3, and FIG. 8B shows a state after the attachment.

  After the power changer 14 is attached to the main battery storage unit 3, the opening of the main unit battery storage unit 3 is closed by the lid 12. When the lid is made of a permeable material, it is determined from the outside of the gripping part whether the battery installed in the main battery storage unit is a dry battery, a button-type battery, or nothing is installed. Since it can visually recognize, it is preferable.

  Then, when using a dry cell as a power supply, the power supply changer 14 is removed from the main body battery storage part 3, a dry battery is attached to the main body battery storage part 3, and the event light-emitting device 1 is used.

  The above is the basic configuration of the present invention. However, in the case where a button-type battery is used instead of a dry battery in an apparatus, equipment, or the like based on the use of a dry battery, the following specific problems may occur. In the example of the above embodiment, the AAA batteries (three) are usually used, and in the computer as the control unit attached to the gripping unit, the current / voltage amount to the light source is such a power source ( It is set in accordance with 3 AAA batteries. If the button-type battery (six LR44 types) is mounted and used in this set state, the power of the button-type battery is consumed in a very short time.

  That is, for example, in the case of an event light-emitting device using three 1.0 W LEDs as a light source, a current of about 270 mA from the power source is used to emit light at a brightness at which the event light-emitting device can be used in a normal event. Need to supply. In this case, if AAA alkaline batteries (three, not used) are used, it is possible to emit light for about 10 hours. However, in the event light-emitting device having the same light source as described above, for example, when the current is supplied by an LR44 type button battery (six, unused), the button battery does not use any power. Even if it is, sufficient light emission that can be used as a light-emitting device for events (light emission from the LED) can be obtained only for about 5 minutes (no power), after that it emits light Can only be weak. If power cannot be supplied in such a short time and the light source cannot emit light, the user of the event light-emitting device needs to replace the battery (frequently) during the event, which is inconvenient.

  In order to cope with such a problem, in the present invention, when a power supply changer is mounted in the main body dry cell storage unit and a button-type battery is used as a power source, the amount of current supplied from the power source to the light source is suppressed. Constitute.

  For such a configuration, an example of an event light-emitting device that includes three 0.75 W LEDs as a light source, three AAA alkaline batteries as a power source, and supplies a current of about 170 mA from the power source is taken as an example. explain.

  For example, six button type batteries (LR44 type (1.5V when not in use)) are connected in parallel (three sets are 1.5V x 3 = 4.5V when not in use) As the light emitting device for events in the case of using a power source, a device that uses three 0.06 W LEDs as a light source and supplies a current of about 45 mA from the power source to the light source can be mentioned. In this case, if the battery is unused, the LED can emit light for about 10 hours.

  Therefore, when the power supply changer 14 storing the button-type battery 22 is mounted in the main battery storage unit 3, when the power input switch 4 of the event light-emitting device is turned on, the power source (button-type battery 22) from the power supply changer is used as the light source. The current supplied to (LED) is configured to be 45 mA, for example.

  Specifically, in the present embodiment, the grip unit 2 and the power supply changer 14 are each provided with a first control unit and a second control unit (not shown) provided therein. These control units have a function as a computer.

  When the power input switch 4 of the light emitting device for events is turned on with the power changer 14 storing the button-type battery 22 mounted in the main battery dry cell storage unit 3, the second control unit provided in the power supply change unit 14 is turned on. Regardless of the remaining power level of the button-type battery 22 attached for a predetermined time (T1) after receiving the start signal, for example, for 5 seconds, a predetermined constant current amount (A1), for example, 4. 2V is supplied to the first controller.

  Thereafter, the second control unit supplies the first control unit with an amount of current (A2) corresponding to the remaining power of the attached button-type battery 22. When the set of button-type batteries is unused (hereinafter referred to as “unused example”), the remaining power is 4.5 V as described above. Supply to the control unit. In addition, when a battery that has already been used slightly is used and the total remaining power of one set (three button-type batteries described above) is, for example, 3.8 V (hereinafter referred to as “use example”), it is 3.8 V. A current is supplied to the first control unit.

  The second control unit supplies a constant current amount (A1) to the first control unit for a predetermined time (T1) regardless of the remaining power level of the battery. A1 is 4.2V with respect to the remaining amount of 4.5V), and in the usage example, a boosting function (A1 is 4.2V with respect to the remaining amount of power of 3.8V) is performed.

  On the other hand, the first control unit provided in the grasping unit 2 receives the supply of the current amount (A1) for a predetermined length of time (T2) from the second control unit. The amount of current supplied to the light source is controlled so that the attachment is recognized and a predetermined amount of current (A3) is supplied to the light source (LED). T2 can be the same as T1. That is, in the above example, when the first control unit recognizes that the current of 4.2 V (A1) has been supplied for 5 seconds as T2, the power supply changer 14 (the button-type battery 22 is stored in the main battery storage unit 3). ), For example, a current of 45 mA (button battery current) is supplied to the light source (LED) as A3.

Here, when the power supply changer 14 in which the button-type battery is stored is mounted in the main battery storage unit 3, the second control unit controls the current to be supplied to the first control unit at a predetermined voltage for a predetermined time. The reason is as follows.
First, in order to control (limit) the amount of power supplied to the light source when a power supply changer (button-type battery) is installed in the main battery compartment of an event light-emitting device that is originally powered by a dry battery, the event light-emitting device It is necessary to make the main body (the first control unit provided in the gripping part in this embodiment) recognize that the power source has been changed to the button type battery. Therefore, a second control unit is provided in the power supply changer, and when the power supply changer is mounted in the main battery storage unit and the event light-emitting device is switched on, a constant amount of current (4.2 V in the above example) is supplied. To be configured.
On the other hand, for example, in the AAA type battery, as a result of the decrease in the remaining amount of power due to use, the voltage when the current is supplied to the first control unit accidentally becomes the set value (4.2 V). It can happen. Therefore, it is assumed that the current is supplied at the set value for a certain length of time (in the above example, 5 seconds). The power supply from the dry battery is not always stable, and the dry battery has the property that if it is not controlled, it is difficult to supply power for a certain length with a constant amount of current. In this embodiment, this property is used.
That is, even if a used AAA type battery has a short time (for example, 0.2 seconds) at a set value, the current is supplied at a constant voltage for a certain length of time. The possibility of being supplied is low. Therefore, if the second control unit is configured to supply a current for a predetermined time at a predetermined voltage to the first control unit, a power supply changer (including a button-type battery) is stored in an event light-emitting device that originally uses a dry cell. ) Will be recognized correctly when worn.

  In the above example, T2 (recognized time setting value in the first control unit = recognizing that the power supply changer is attached when the current amount is supplied by a predetermined voltage for the time) is, for example, 3 The second may be set to be shorter than T1 (supply time from the second control unit; in this example, 5 seconds). According to this, it is possible to cope with errors that may occur between the two control units (even if the second control unit supplies for 5 seconds, the first control unit cannot accurately recognize the supply for 5 seconds). Become.

  If the first control unit does not recognize the constant current (A1) in the above-mentioned fixed time (T2), it is assumed that a dry battery (three AAA batteries) is attached, and a current for the dry battery (for example, 170 mA) is assumed. Supply to a light source (LED).

To summarize the above, referring to FIG. 9, the second control unit determines in advance regardless of the remaining amount of power of the attached button battery for a predetermined time (T1) after receiving the lighting start signal. The supplied constant current amount (A1) is supplied to the first control unit, and then the current amount (A2) corresponding to the remaining power of the attached button battery is supplied to the first control unit.
The first control unit recognizes the attachment of the power supply changer only when receiving a supply of the current amount (A1) for a predetermined length of time (T2) from the second control part, and for the power supply changer (ie, In this case, a predetermined amount of current (A3) is supplied to the light source. On the other hand, the first control unit recognizes the power source as a dry cell and is suitable for a dry cell when it receives a current amount different from A1 from the second control unit or receives a supply of A1 for a time different from T2. The amount of current (A4) is supplied to the light source (LED).

  With this configuration, when a power supply changer (containing a button-type battery) is attached, power corresponding to the button-type battery is supplied to the light source, and thus a large amount of power is originally consumed. Even if a button-type battery with a small amount of stored electricity is used in a light emitting device for events in which a dry battery is used with a high-output, high-brightness LED as a light source, it is possible to supply power to the light source for a long time.

  Furthermore, since the brightness of light emission is naturally limited due to the limited amount of power supplied to the light source, even if a high-power, high-brightness LED is attached to the light source, the light emission (brightness) of the LED Is limited. Therefore, it is possible to meet the needs of event organizers when it is desired to suppress the degree of light emission (brightness).

  The set values are merely examples, and can be changed as appropriate (the same applies to the following embodiments).

(Embodiment 2)
As a means to suppress the amount of current supplied from the power source to the light source when the button-type battery is used as the power source by attaching the power supply changer to the main battery storage unit, in the first embodiment, as described above, the two control units ( The first control unit and the second control unit) are used to supply a constant amount of current for a certain period of time, and to determine based on the magnitude of the current amount. On the other hand, in this embodiment, based on the structure of the power supply changer 14 and the main body dry cell storage part 3, it is discriminate | determined whether a power supply is a dry cell or a button type battery. As the control unit, only one provided in the gripping unit is used.

  FIGS. 10 to 13 show examples of the main battery storage unit according to the present embodiment in different states (FIG. 10 shows a state where the dry battery 10 is attached, FIGS. 11 to 13 show a state where no battery is attached), or From different directions (FIGS. 10 to 11 are views seen from the front, FIG. 12 is a view seen from the front oblique upper side, and FIG. 13 is a view seen from the oblique lower front side). The main battery storage unit is configured such that three AAA batteries are mounted in parallel. Here, being attached in parallel means not a parallel connection of circuits but a physical arrangement of dry batteries (arranged in parallel, arranged side by side).

  In the present embodiment, the dry batteries are arranged in parallel as described above, but the electrical connection (circuit) is a series connection (series connection). In order to achieve such a series connection, the battery contact members are installed on the upper part of the main battery storage unit (the upper part when referring to the figure, for example, FIG. 2) and the lower part (similarly, the lower part when referring to, for example, FIG. 2). To do. The battery contact member can also be constituted by a battery spring, a battery leaf spring, or the like. An example of the battery contact member is shown in FIGS. The battery contact member 36 of FIG. 14A is arranged at the upper part of the main body dry battery storage part, and the battery contact member 37 of FIG. 14B is arranged at the lower part of the main body dry battery storage part.

  In the plurality of dry batteries, the positive electrode and the negative electrode are in contact with the respective electrodes of the battery contact member. That is, referring to FIG. 10 to FIG. 13, the first dry battery is in contact with A +, A−, the second dry battery is in B +, B−, and the third dry battery is in contact with C +, C−. It is attached to the storage unit. When the dry battery is attached and the power is turned on, the terminal of the dry battery and the electrode of the battery contact member are electrically connected, and power is supplied from these series-connected dry batteries.

  In the example shown in FIGS. 10 to 14, the current from the power source (dry cell) flows as “A +” → “A−” → “B +” → “B−” → “C +” → “C−”. Become. On the electrode A + side, a one-end-side connection member that can electrically connect the control unit provided in the gripping part and the electrode A + is provided. The one end side connecting member can be a metal fitting or wiring as shown by 24 in FIG. 16, for example. Furthermore, a C-battery contact member of the battery contact member 37 (see FIG. 14B) and the other end side connection member that can electrically connect the control unit provided in the grip portion are provided (note that The control unit is electrically connected to the light source). The other end side connection member is preferably a wiring as shown by 25 in FIG. 16, for example, but may be a metal fitting. The wiring or the like can be covered with a resin or the like to prevent a short circuit.

  On the other hand, the power supply changer of the present embodiment is provided with a portion (power supply changer terminal) that can be electrically connected to the battery contact member of the main battery storage unit on the outside. Here, when a dry cell is used in the present embodiment, the dry cell is connected in series as described above, but the power changer terminal is provided so as to be at one end and the other end of the series connection. That is, the power supply changer terminal has one positive electrode contact portion (positive electrode terminal) 18 (see FIGS. 15 and 5 to 7) and one negative electrode contact portion (negative electrode terminal) 19 (FIGS. 15 and 6 to 6). FIG. 7), only two in total. The positive electrode terminal 18 contacts the electrode (A +) (see FIG. 13) located at one end of the series connection of the battery contact member. The negative electrode terminal 19 is in contact with the electrode (C−) (see FIG. 12) located at the other end of the series connection of the battery contact member.

  From the above, in this embodiment, when a dry battery is used as a power source, current is supplied to all the electrodes (A +, A−, B +, B−, C +, C−) of the battery contact member by being connected in series. On the other hand, in the case of a button type battery, the button type battery is attached to the button type battery storage part for changing the power changer (so as to be connected in series), and the power source changer is attached to the main battery dry battery storage part. When the power is turned on in a state, a current flows directly from A + to C−, and electrodes (A−, B +, B−, C +) that are not energized in the battery contact member are generated. In the present embodiment, such a difference in configuration is used.

  That is, when all the electrodes of the battery contact member are energized, a predetermined amount of current corresponding to the dry battery is supplied to the light source, and when an electrode that is not energized is generated, a predetermined amount corresponding to the button battery is generated. The current amount is supplied to the light source.

  More specifically, while the dry batteries of this embodiment are electrically connected in series, the dry batteries are arranged in parallel in the main battery dry cell storage part, so when using a power supply changer, one end of the series connection. It is possible to supply power to the light source while generating an electrode that is not energized in an electrode located in the middle other than (A +) and the other end (C−). In this case, since the non-energized electrode is energized when a dry battery is attached, the presence / absence of energization at this electrode is used as a reference for determining whether the attached power source is a dry battery or a power supply changer (button type battery). It becomes possible.

  For example, the electrode C + (one of the battery contact members) located in the middle of the series connection and the control unit provided in the gripping part are configured to be electrically connectable. As shown in FIG. 16, an intermediate electrode connecting member 27 is provided for connection between the control unit 26 and C +. A metal fitting or wiring can be used for the intermediate electrode connecting member.

  When power is input, the electrode C + is energized when a dry cell is attached. When a button-type battery (power changer) is attached, the electrode C + is not energized. Therefore, when the electrode C + is energized and the control unit 26 provided in the gripping unit is energized by the electrical connection described above, the control unit is configured to supply a dry battery current (for example, 170 mA) to the light source (LED). 26 is configured. Further, when the electrode A + and the electrode C- are energized without the electrode C + being electrically connected, the control unit 26 is configured such that a current (for example, 45 mA) for the button battery is supplied to the light source (LED). .

  By configuring in this way, the same effect as in the case of the first embodiment can be obtained. In other words, in a light emitting device for events that uses a high-power, high-brightness LED that consumes a lot of power as a light source and uses a dry battery, even if a button-type battery with a small amount of electricity is used, power is supplied to the light source for a long time. Even if a high-power, high-brightness LED is attached to the light source, the light emission (brightness) of the LED is limited. Can meet the needs of the elderly. Furthermore, according to the present embodiment, a current for a dry battery or a current for a button battery (using a power supply changer) is selectively supplied to a light source depending on whether or not a specific electrode (electrode of a battery contact member) is energized. Therefore, it is possible to further suppress the occurrence of malfunction. Further, since the control can be performed only by the control unit of the gripping unit, not only the occurrence of malfunction but also the occurrence of failure can be further avoided.

(Embodiment 3)
In this embodiment, instead of the amount of current (Embodiment 1) and the position of the electrode (Embodiment 2), as a power source discriminating means, by using a dry cell discriminating means for discriminating that a dry cell is attached, Change the type.

  In the present embodiment, the dry cells are electrically connected in series as in the second embodiment, and are arranged in parallel in the main body dry cell housing (the same parallel arrangement as in the second embodiment). A power supply changer having the same configuration as that of the second embodiment can also be used. As the control unit, only one provided in the gripping unit is used.

  In the present embodiment, as shown in FIGS. 17 to 19, a dry cell discrimination means 23 is provided in the main body dry cell storage unit. In FIG. 17 and FIG. 19, the dry battery discriminating means 23 is shown from the front. However, when the dry battery is not attached to the main body dry cell storage portion, it protrudes in the front direction in these drawings. The signal is input by being naturally pressed by the dry battery. When the dry battery is removed and released from this pressing force, the dry battery discrimination means 23 returns to the protruding state. For this, a known switch means can be used. For example, a plate spring or a coil spring can be used to make contact when pressed, and the contact can be released when released.

  As shown in FIG. 18, on the back side of the dry battery discriminating means 23, there is provided a dry battery discriminating means connecting member 28 that is electrically connected to a control portion provided in the gripping portion. This connecting member can be constituted by wiring or the like. The dry battery discrimination means functions as a switch.

  On the other hand, when the power supply changer is attached, the shape and size of the power supply changer, the position of the dry battery determination means 23, etc. are determined so that the dry battery determination means 23 is not pressed (no signal is input). As shown in FIG. 19, when the power supply changer is attached to the main body battery storage part, a space 30 is provided between the side surface 29 of the main body battery storage part and the power supply changer 14. The dry battery discriminating means 23 is arranged in this space 30. As long as the place where the dry battery discriminating means is arranged is in the space, basically any place is possible.

  Note that the position of the dry battery determination means may not be the position shown in the figure, and may be provided, for example, at the attachment position (space 31) of the dry battery on the left side in FIG. However, when the power supply changer is attached to the main battery storage unit, the dry battery discrimination means is not pressed (no signal is input).

  When the dry cell discrimination means 23 is pressed and the control unit 26 receives the input signal, the control unit 26 is configured so that a dry cell current (for example, 170 mA) is supplied to the light source (LED). Further, when the electrode A + and the electrode C- are energized without pressing the dry battery discrimination means 23, the control unit 26 is configured so that a button battery current (for example, 45 mA) is supplied to the light source (LED). .

  By configuring in this way, the same effect as in the case of the first embodiment can be obtained. Furthermore, since the current for the dry cell or the current for the button battery (using the power supply changer) can be supplied to the light source depending on whether or not the dry cell discrimination means is pressed, it is possible to further suppress the occurrence of malfunction. . Further, since the control can be performed only by the control unit of the gripping unit, not only the occurrence of malfunction but also the occurrence of failure can be further avoided.

(Embodiment 4)
In this embodiment, the power supply changer and switching means for switching the battery type (dry battery and button-type battery) are used in combination to change the battery type.

  In the present embodiment, the dry batteries are electrically connected in series as in the second and third embodiments, while being arranged in parallel with the main body dry battery storage unit 3. A power changer having the same configuration as in the second and third embodiments can also be used. As the control unit, only one provided in the gripping unit is used.

  In the present embodiment, the switching means is provided outside the main body dry cell storage unit. As an example, as shown in FIGS. 20 to 22, the switching means 32 can be provided in the upper edge portion of the main body dry cell storage unit 3. The switching means 32 is flush with the edge portion (or can be recessed in the pressing direction). When the power supply changer 14 is attached to the main body dry cell storage unit 3, the main body dry cell storage unit is covered with the power supply changer lid 33. The power changer lid 33 is provided with a convex portion 35 as a pressing portion at a position corresponding to the switching means. When the power changer lid 33 is attached, the switching means 32 is pressed by the convex portion 35 and the signal is changed. Is entered. When the power changer lid 33 is removed and released from this pressing force, the switching means 32 returns to the original state. For this, a known switch means can be used. For example, a plate spring or a coil spring can be used to make contact when pressed, and the contact can be released when released.

  On the back side of the power changer lid 33, it is preferable to provide a fixing means for suppressing the button-type battery housed in the power changer 14 and preventing the position thereof from shifting when attached. The fixing means may be a convex portion or the like extending in the longitudinal (vertical) direction on the back side of the power supply changer lid 33.

  As shown in FIG. 22, on the back side of the switching unit 32, a switching unit connection member 38 that is electrically connected to a control unit provided in the gripping unit is provided. This connecting member can be constituted by wiring or the like.

  On the other hand, when the dry battery 10 is attached instead of the power changer, as shown in FIG. 20, a dry battery lid 34 having no convex portion is used, thereby covering the main battery dry battery storage 3. Since the dry cell lid 34 does not have a convex portion, the switching means 32 is not pressed, and no input is made by the switching means 32.

  When the switching means 32 is energized from the electrode A + to the electrode C− without being pressed, the control unit 26 is configured so that a dry battery current (for example, 170 mA) is supplied to the light source (LED). In addition, when the switching unit 32 is pressed and the control unit 26 receives the input signal, the control unit 26 is configured such that a button battery current (for example, 45 mA) is supplied to the light source (LED).

  By configuring in this way, the same effect as in the case of the third embodiment can be obtained. Moreover, since the switching means is pressed by the convex part of the lid for the power supply changer and the dry battery does not contact the switching means, the dry battery is not damaged by the switching means.

(Modification)
As is clear from the above description regarding the third and fourth embodiments, these embodiments can be used by being modified.

  For example, with respect to the third embodiment, in the third embodiment, the protruding dry cell discrimination means 23 is provided in the main body dry cell storage unit, and the dry cell presses this, while the power changer does not press this, but the reverse It can also be configured. That is, referring to FIG. 17, for example, in the vicinity of the position where the dry battery discriminating means 23 is located, a button-type battery discriminating means which is flush with or recessed from the main body dry cell storage portion (see Embodiment 4) is provided as a power discriminating means. With this configuration, when a dry cell is attached to the main unit dry cell storage unit, the button-type battery discriminating means is not pressed (switch input). On the other hand, the power supply changer is provided with a convex portion that can press the button-type battery discriminating means and input a switch when the power supply changer is attached to the main body dry cell storage unit. When the convex portion presses the button-type battery discriminating means, the control unit 26 receives the input signal and configures the control unit 26 so that a button-type battery current (for example, 45 mA) is supplied to the light source (LED). To do. When the button-type battery discriminating means is not pressed, the control unit 26 is configured such that when the power is input, the dry battery current is supplied to the light source.

  The dry battery discrimination means has a function of causing the control unit to sense that the attached battery is a dry battery, and the button-type battery discrimination means senses to the control unit that the attached battery is a button-type battery. It has a function to make it. These are collectively referred to as power source discrimination means.

  Next, regarding the fourth embodiment, in the fourth embodiment, the power changer lid 33 is provided with a convex portion 35 as a pressing portion, and when the power changer lid 33 is attached, the switching means 32 is pressed by the convex portion 35. Although a signal is input, a convex portion as a pressing portion is provided on the lid for the dry cell, and when the dry cell is attached and the lid for the dry cell is attached, the switching means is pressed, and the current for the dry cell (for example, 170 mA) May be configured such that is supplied to the light source (LED).

  Further, in the fourth embodiment, the switching means is flush or recessed at the installation location, and the pressing portion is formed by a convex portion. However, the switching means protrudes at the installation location, and the power changer lid or the dry cell lid It is also possible to configure not to press the pressing portion, for example, by cutting out a position corresponding to the pressing portion in any one of the above. Since the other lid (the lid for the power changer or the lid for the dry battery) does not have a notch or the like, it presses the pressing portion. And when a press part is pressed, a control part is comprised so that the electric current for dry batteries or the electric current for button type batteries may be supplied to a light source (LED).

(Embodiment 5)
When the current supply amount is lowered according to the power source (in the above example, from 170 mA for AAA type batteries to 45 mA for button type batteries), there may be a problem in the color mixing and toning of the emitted colors. For example, in the case of an event light emitting device using RGB LEDs, in order to obtain a plurality of light emission colors, a predetermined LED (for example, a red LED and a blue LED) of RGB is caused to emit light and mixed to obtain a desired light emission color ( For example, a purple emission color) is obtained. However, for example, when obtaining a white light emission color with RGB, if the power supplied is weak, light emission necessary for color mixing and color matching is not necessarily obtained from all LEDs, and the balance is lost. As a result, in reality, there is a bias in color, such as strong white in green and strong white in blue, or a white emission color cannot be obtained over time (decrease in battery power) Occurs.

  In this way, for example, if the current supply amount is suppressed in an event light emitting device using RGB LEDs, the brightness is not simply lowered (darkened), but the color balance (color balance) due to color mixture is broken. In addition, there may be a problem that the brightness is lowered. The loss of color balance becomes more noticeable when the amount of current supplied is weakened.

  With regard to this point, the inventor has shown by experiment that when a plurality of LEDs emit light and mix colors to obtain a desired emission color, the ratio (mixing ratio) at which the emitted LEDs should be mixed or blended varies depending on the amount of current. Obtained knowledge.

  That is, in the above example, when an RGB LED is used as a light source, a AAA type battery is used, and the LED is caused to emit and mix colors by a current of 170 mA to obtain a purple emission color as a desired emission color, the red LED is used. It is conceivable to mix about 50% of the light and about 50% of the light from the blue LED. On the other hand, when the same RGB LED is used as the light source, and a button-type battery is used to emit and color the LED with a current of 45 mA to obtain the same emission color, the light from the red LED is about 30%, the blue LED It is preferable to add about 70% of the light from

  From the above, when the first control unit is supplied with the current amount (A2) for a predetermined length of time (T2) from the second control unit and recognizes the installation of the power supply changer, the current amount (A1) In addition to controlling the amount of current supplied to the light source so as to be supplied to the light source, the composition ratio of light emission from each LED for obtaining a desired light emission color is changed (controlled).

  According to this, even if the supply current amount is changed, the light emission colors of the LEDs are mixed at a blending ratio corresponding to the current amount. Therefore, the intended light emission color is changed by changing the supply current amount. And a desired color can be easily obtained.

  In addition, considering that the brightness at the time of light emission is weakened due to a decrease in the amount of supplied current, the light emission color that can be easily recognized as a desired light emission color at that brightness can be obtained by setting the mixture ratio of the light emission color of each LED It becomes.

  In the case of the first embodiment, the mixing ratio may be set so that the second control unit performs it.

  In the present invention, not only RGB LEDs but also white LEDs can be added to the light sources. For example, when a white LED or a yellow LED is added to an RGB LED, it becomes easy to perform color matching, so that the balance is not easily lost in light emission color generation by color mixing. For this reason, even when the brightness of light emission is lowered, it becomes easier to obtain a desired light emission color, and this is easily maintained. The change and control of the mixing ratio of the luminescent color from each LED can also be appropriately performed.

(Embodiment 6)
In the present invention, it is also possible to configure the grip portion of the event light emitting device so as to be based on the use of a button-type battery, and to use a power supply changer when using a dry battery.

  In this case, the grip portion of the event light emitting device is provided with a main body button type battery storage portion as a main body battery storage portion for attaching a button type battery serving as a power source. To use. Further, the power changer includes a changing dry cell storage unit for attaching a dry cell, and is configured to be detachably attached to the main body button type battery storage unit. When the power supply changer to which the dry battery is attached is attached to the main body button-type battery storage unit, the type of battery as the power source for the event light-emitting device is changed from the button-type battery to the dry battery.

  Other control structures and the like are appropriately configured in accordance with this embodiment while conforming to the first to fifth embodiments.

  Recently, with respect to the use of light emitting devices for events, there is a tendency that different regulations are made for each event, and in particular, there is a situation where the use of light emitting devices for events using a dry battery as a power source is restricted (prohibited). When there is such a restriction, the event participant needs to use a light emitting device for events that uses a button-type battery as a power source.

  On the other hand, in events where such regulations are not made, users use light emitting devices for events powered by dry batteries that can be brighter, brighter, stable and obtain many luminescent colors for a long time Often wants to do.

  As described above, according to the present invention, in a situation where the event light emitting devices that can be used for each event or event venue are different, according to the present invention, when the user of the event light emitting device participates in various events, one light emission for the event. Depending on the device, it is possible to take action according to the nature of the event and the rules defined for each event. Moreover, even when a button-type battery is used, it is possible to maintain a sufficient light emission time for events, and it is also possible to obtain a desired light emission color by adding RGB, white LED, yellow LED, etc. and mixing them. Become.

  Therefore, the present invention enables a user who had to have a plurality of event light-emitting devices and participate in various events so far to be able to cope with one event light-emitting device, It responds to the potential demands and demands of users of event lighting equipment.

  Furthermore, even if it is a light-emitting device for events where a high-power, high-brightness LED is attached to the light source, it will be possible to limit the light emission (brightness) of the LED, so we want to reduce the light emission level (brightness) It can also meet the needs of event organizers.

  Moreover, if the holding | maintenance part of an event light-emitting device and the specification of a power supply changer are adjusted, one power supply changer can also be applied to the light-emitting device for events using various LED from which wattage differs.

  The present invention addresses the problems unique to such event light-emitting devices, and has very high industrial applicability in the industry.
