Description

[Technical field]

[0001] The present invention relates to a light-emitting device, and more particularly to a light-emitting device containing a whistle that uses power generated by using liquid. [Background technology]

[0002] As the number of people enjoying outdoor activities such as fishing, mountain climbing, and camping increases, the number of incidents and accidents that can occur outdoors tends to increase.

[0003] In the outdoors, accidents and incidents such as getting lost or falling are more likely to occur in dark environments after sunset. As a result, lighting equipment that emits light such as flashlights is needed as a measure to prevent such accidents and incidents.

[0004] Unlike indoor environments, in outdoor environments, devices for producing light need to be powered by a battery.

[0005] Batteries are broadly classified into primary batteries and secondary batteries. Primary batteries are disposable batteries that cannot be recharged after being discharged once and cannot be reused. Secondary batteries are batteries that can be used repeatedly and can be recharged after being discharged and reused.

[0006] Primary batteries and secondary batteries each have their own advantages and disadvantages. Primary batteries generally have the advantage of being safer than secondary batteries and being lighter in size and weight relative to the amount of power they generate, while secondary batteries are considered to be inferior to primary batteries in terms of safety, size, and weight, but have the advantage of being able to be used repeatedly by recharging. Users can select the appropriate type of battery to use depending on the situation, taking into account the advantages and disadvantages mentioned above.

[0007] For example, as a disposable flashlight to be used outdoors in emergencies or at outdoor events, a flashlight that uses a primary battery may be more appropriate than a secondary battery. [Prior art documents] [Patent documents]

[0033] Various embodiments and / or aspects are disclosed below with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are disclosed to aid in the overall understanding of one or more aspects. However, one of ordinary skill in the art of the present disclosure will recognize that such aspect(s) can be practiced without such specific details. The following description and accompanying drawings detail certain exemplary aspects of one or more aspects. However, these aspects are illustrative, and some of the various methods based on the principles of the various aspects may be utilized, and the description provided herein is intended to include all such aspects and their equivalents. In particular, any aspect or design described herein as an "embodiment," "example," "aspect," "exemplary," or the like is not necessarily to be construed as superior or advantageous over other aspects or designs.

[0034] Hereinafter, the same or similar components are denoted by the same reference numerals, regardless of the reference numerals in the drawings, and duplicated descriptions thereof will be omitted. In addition, when describing the embodiments disclosed in this specification, if it is determined that a detailed description of a related known technology may make the gist of the embodiments disclosed in this specification unclear, the detailed description will be omitted. In addition, the attached drawings are merely intended to facilitate understanding of the embodiments disclosed in this specification, and the technical ideas disclosed in this specification are not limited by the attached drawings.

[0035] Although the terms "first" and "second" are used to represent various components, it is obvious that these components are not limited by these terms. These terms are used merely to distinguish one component from another. Therefore, it is obvious that the first component described below can also be the second component in the technical concept of the present invention.

[0036] Unless otherwise defined, all terms (including technical and scientific terms) used in this specification are to be interpreted as meanings commonly understood by those having ordinary knowledge in the technical field to which the present invention belongs. Furthermore, terms defined in general dictionaries are not to be interpreted ideally or excessively unless otherwise defined.

[0037] Additionally, the terms "or", "or" and "alternative" are intended to mean the inclusive "or", "or" and "alternative" rather than the exclusive "or", "or" and "alternative". In other words, unless otherwise specified and unless otherwise clear from the context, "X utilizes A or B" is intended to mean one of the natural inclusive permutations. In other words, if X utilizes A; X utilizes B; or X utilizes both A and B, then "X utilizes A or (or) B" can apply to any of these. Additionally, the term "and / or" as used herein refers to and includes all possible combinations of one or more of the associated listed items.

[0038] Additionally, the term "comprise" as a predicate and / or the modifier "comprise" are understood to mean the presence of the stated feature and / or component, but not to exclude the presence or addition of one or more other features, components and / or groups thereof. Additionally, unless a specific number is specified or the context is clear that a singular number is indicated, the singular number should generally be construed in this specification and claims to mean "one or more."

[0039] When an element or layer is described as being "on" or "on" another element or layer, it does not only mean that it is directly on the other element or layer, but also includes cases where there are other layers or elements between them. On the other hand, when an element is described as being "directly on" or "immediately above" it means that there are no other elements or layers between them.

[0040] Spatially relative terms such as "below," "beneath," "lower," "above," "upper," and the like, may be used to easily describe the relationship of one component to another as depicted in the drawings. Spatially relative terms should be understood to include different orientations of each element in use or operation in addition to the orientation depicted in the drawings.

[0041] For example, if components depicted in the figures were turned upside down, a component described as "below" or "beneath" another component would then be located "above" the other component. Thus, the exemplary term "below" can encompass both an orientation of below and above. Components may be oriented in other directions, and thus spatially relative terms may have different interpretations depending on the orientation.

[0042] Additionally, as used in this disclosure, the terms "instrument" and "device" may be used interchangeably.

[0043] The objectives and effects of the present disclosure, as well as the technical configuration for achieving them, will become clear by referring to the following detailed examples together with the accompanying drawings. In the description of the present disclosure, if it is determined that a specific description of a known function or configuration may make the gist of the present disclosure unclear, the detailed description will be omitted. The terms described below are defined in consideration of the functions in the present disclosure, and may change depending on the intentions or practices of users or operators.

[0044] However, the present disclosure is not limited to the embodiments disclosed below, and can be embodied in various forms. These embodiments are provided solely for the purpose of making the present disclosure complete and allowing those skilled in the art to fully understand the scope of the disclosure, and the present disclosure is defined by the scope of the claims. Therefore, the definition should be determined based on the contents described throughout this specification.

[0045] In the present disclosure, a light-emitting device may refer to a device including a light-emitting unit that generates light using electric power. For example, a light-emitting device may refer to any type of device including a unit that receives an electric supply and emits light (e.g., an LED (light-emitting diode), etc.).

[0046] In this disclosure, "electrically connected" can mean connected by metal, wire, wireless, etc. so that a voltage is generated and a current flows.

[0047] FIG. 1 is a diagram for explaining an example of a light emitting device according to several embodiments of the present disclosure.

[0048] 1, the light emitting device 100 may include a body 110 and a light emitting part 120. The light emitting device 100 may further include a cover 130.

[0049] In one embodiment, the body 110 corresponds to the body of the lighting device 100 and can include a battery that generates power using a chemical reaction between the liquid, magnesium, and oxygen. In one embodiment, the body 110 can correspond to a housing that defines the exterior of the lighting device 100.

[0050] In one embodiment, the liquid may include water, urine, saliva, and the like.

[0051] In one embodiment, the light emitting unit 120 may be electrically connected to the body 110 and / or the battery, and may be configured to emit light by receiving power generated by the battery.

[0052] In one embodiment, the light emitting unit (120) may be at least one of an incandescent light bulb, a fluorescent light bulb, and an LED light bulb.

[0053] In one embodiment, the body (110) may further include a liquid supply (not shown) in communication with at least one end of the battery to supply liquid to the battery for use in supporting the battery's power generation.

[0054] In one embodiment, the lighting device (100) may further include a liquid storage section (not shown) for storing liquid to be supplied to the battery, and a liquid injection section configured to supply liquid from the liquid storage section to the battery in response to a user input including whether or not to inject liquid from an injection input section of the main body (110).

[0055] In one embodiment, the liquid storage unit may be provided in the form of a tank or a water tank, which may be a part of the light emitting device (100) and / or a separate device from the light emitting device (100).

[0056] In one embodiment, the liquid ejection unit can be a device in the form of a spray, a hose, or a water pipe. As an example, the liquid ejection unit can be operated in response to an input from a user input unit (e.g., a button) located on the outer surface of the main body (10). In the above example, the liquid ejection unit can control the speed of ejected liquid or the amount of ejected liquid based on the input strength or input duration at the user input unit. As an example, the amount of liquid ejected per unit time can be determined in proportion to the duration of the user input applied to the user input unit.

[0057] In one embodiment, the liquid injection unit can perform a function of supplying or blocking liquid between the liquid storage unit and the battery. For example, the liquid injection unit can have a shape of a slidable door, and can perform a sliding movement of the door to transfer the liquid in the liquid storage unit to the battery. When the sliding door is in a closed position, the liquid in the liquid storage unit can be physically blocked from moving to the battery. When the sliding door is in an open position, the liquid in the liquid storage unit can be physically allowed to move to the battery. As another example, the liquid injection unit can have a shape of a door that performs a hinge movement, and the liquid in the liquid storage unit can be transferred to the battery by the hinge movement of the doors on both sides.

[0058] In an embodiment, the light emitting device 100 may further include various sensors. For example, the sensor may be connected to the outer surface of the light emitting device 100, may be included inside the light emitting device 100, or may be located and operated in a separate device separate from the light emitting device 100. For example, the sensor may be electrically connected to a battery of the light emitting device 100 and may perform a sensing operation for triggering the operation of the light emitting device 200. For example, if the sensor is located inside the light emitting device 100, the sensor may be located adjacent to a liquid supply unit of the light emitting device 100 and may sense the amount of water and / or liquid in the water supply unit. For example, if the sensor is located adjacent to a light emitting unit of the light emitting device 100, the sensor may be configured to detect the amount of light emitted by the light emitting unit (e.g., light intensity such as illuminance). For example, if the sensor is located near a battery inside the light emitting device 100, the sensor may be configured to sense the amount of power of the battery.

[0059] The liquid ejection unit is capable of automatically supplying liquid based on first sensing data acquired from a first sensor that detects liquid around the liquid supply unit or the battery.

[0060] In one embodiment, the first sensor may be a sensor coupled to the liquid supply and / or battery that senses moisture and / or liquid present in the liquid supply and / or battery. For example, the first sensor may be a resistive moisture sensor that uses the principle that electrical resistance between two electrodes changes depending on humidity or moisture content, and the electrical resistance decreases as humidity increases; a capacitive moisture sensor that measures the capacitance at the contact point with soil or an object to detect moisture content, and the capacitance increases as the moisture content increases; an optical moisture sensor that measures the absorption and reflection of light to measure the humidity of soil or an object, and changes the characteristics of the light detected by the optical sensor as the humidity of the object or soil increases; a flow-based moisture sensor that detects the flow of water or liquid, measures the moisture content, and calculates the moisture content by estimating the water content from the flow rate or the total weight of the object; a microwave moisture sensor that detects the humidity of an object using microwave wavelengths; and a contact sensor that measures the electrical conductivity of a liquid using electrical contact, or detects a liquid using resistance, capacitance, inductance, etc. The liquid level sensor may include a liquid level sensor that measures the transmission or reflection of light to detect the presence or absence of liquid, a capacitive sensor that measures the electrical capacitance to detect the presence or absence of liquid, and / or a conductivity sensor that measures the conductivity of the liquid to confirm the type and concentration of the liquid.

[0061] In one embodiment, the first sensing data may include data corresponding to the presence or absence of liquid, the amount of liquid, etc. obtained from the first sensor.

[0062] In one embodiment, the liquid ejection unit compares the first sensing data acquired from the first sensor with a liquid threshold value, and if the value of the first sensing data is smaller than the liquid threshold value, determines that there is a shortage of liquid and automatically supplies liquid. For example, the liquid ejection unit can automatically adjust the amount of liquid supplied based on the first sensing data.

[0063] In one embodiment, the liquid threshold can be the amount of liquid in ml or the water content in %.

[0064] In one embodiment, the liquid ejection unit can automatically supply liquid based on second sensing data obtained from a second sensor that senses the power of the battery and / or the light-emitting unit.

[0065] In one embodiment, the second sensor may be a sensor for detecting a current flowing through the battery and / or the light emitting unit, and may include, for example, a Hall sensor that measures a current due to a change in a magnetic field, or a resistance / voltage measurement sensor that measures power by measuring the resistance of a circuit and calculating a voltage based on the current and resistance.

[0066] In one embodiment, the liquid ejection unit is capable of comparing second sensing data obtained from the second sensor with a power threshold value, and automatically supplying liquid if the value of the second sensing data is smaller than the power threshold value.

[0067] In one embodiment, if the maximum illuminance of the light emitter is 500 lux, the power threshold may be 250 lux.

[0068] In one embodiment, the lighting device (100) may further include a third sensor for sensing temperature, which is used to protect the lighting device (100).

[0069] In one embodiment, the light emitting device (100) can interrupt the operation of the liquid supply unit and / or cut off the power supply to the light emitting unit by operating a switch (not shown) configured to selectively cut off the electrical connection between the battery and the light emitting unit based on the third sensing data acquired from the third sensor. As an example, the switch can be made of a non-conductive material, and in order to cut off the electrical connection between the battery and the light emitting unit, the switch can be moved to a cut-off position to physically cut off the connection between the battery and the light emitting unit. As an example, the switch can be made of an insoluble material, and in order to interrupt the operation of the liquid supply unit, the switch can be moved to a cut-off position to block the portion from the liquid supply unit toward the battery.

[0070] In one embodiment, the third sensor may include a thermocouple, which is composed of two wires of different metals and calculates temperature by measuring the thermoelectric power generated at the point where the two wires are connected; a resistance temperature detector (RTD), which measures temperature by utilizing the characteristic that electrical resistance changes linearly with temperature; a thermistor sensor made of a semiconductor element and whose electrical resistance changes greatly with temperature; an infrared temperature sensor, which calculates temperature by measuring infrared radiation emitted from the surface of an object; and / or a thermocouple, which calculates temperature by sensing thermoelectric power generated by temperature and converting it into a voltage.

[0071] In one embodiment, the switch (not shown) may correspond to switch 220 coupled to body 210 or may be a separate switch.

[0072] For example, the switch (not shown) can be a device structured to physically cut off electrical contact between the liquid supply unit and the battery, between the battery and the light-emitting unit, and / or within the battery.

[0073] In one embodiment, the switch (not shown) can be automatically actuated by a sensor and / or can be a device that is manually actuated by a user. In an example of manual actuation, the switch can operate in response to a user input applied to a user input formed on the exterior surface of the body 110.

[0074] In one embodiment, the liquid supply can be configured to absorb liquid from one end of the body 210. For example, the liquid supply can include structures and / or devices that absorb liquid through principles such as osmosis when in contact with liquid at the bottom end of the body 210.

[0075] In one embodiment, the cover 130 can be a lid / base 130. In one embodiment, the lid / base 130 can be detachably coupled to the body 110. For example, the cover 130 can be coupled to the top end of the body 110 as in the light emitting device 100 of reference number 100, or can be coupled to the bottom end of the body 110 as in the light emitting device 100 of reference number 140.

[0076] In one embodiment, when the cover / base part 130 is coupled to the upper end of the light emitting device 100, it serves as a cover by covering the light emitting part 120 and can physically adjust the light generated from the light emitting part 120. For example, the cover / base part 130 can reflect the light generated from the light emitting part 120 to block the amount of light emitted outside the cover / base part 130, disperse the light, or change the wavelength of the light to change the visible color.

[0077] In one embodiment, the lid / base 130 can be made of a polymeric material such as plastic.

[0078] In one embodiment, when the cover / base portion (130) is connected to the lower end of the light emitting device (100), it not only stably supports the light emitting device (100), but also serves to store liquid inside the cover / base portion (130) and supply liquid to the battery.

[0079] In one embodiment, reference numeral 140 may be an illustration of an example where light is generated in the light emitting portion 120 of the light emitting device 100 .

[0080] In one embodiment, the light emitter 120 can be powered by a battery to generate light. In one embodiment, the battery can be in contact with a liquid to generate power.

[0081] Another example of the light emitting device (100) is described below with reference to FIG.

[0082] A specific example of a battery in contact with a liquid to generate power is described below with reference to FIGS.

[0083] FIG. 2 is a diagram for explaining another example of a light emitting device according to several embodiments of the present disclosure.

[0084] Referring to FIG. 2, a light emitting device (200) having a cover attached thereto is disclosed.

[0085] In one embodiment, the light emitting device (200) may be provided in the form of a body (210) including a battery, a switch (220) provided on the top of the body (210), a cover (230), and a light emitting unit (240) that is electrically connected to the battery and receives power generated by the battery to generate light, the light emitting unit (240) being attached to the cover (230).

[0086] In one embodiment, the switch 220 can be configured to selectively cut off the electrical connection between the battery and the light emitting unit 240. For example, when the switch 220 is electrically connected to the battery and contacts the cover 230 to which the light emitting unit 240 is attached, the switch 220 can transmit power from the battery to the light emitting unit 240, causing the light emitting unit 240 to emit light. On the other hand, when the switch 220 and the cover 230 are released from their contact state, the power supplied to the light emitting unit 240 is cut off, so that the light emitting unit 240 can no longer emit light.

[0087] In one embodiment, the switch 220 may include a material corresponding to an anode on one side and a material corresponding to a cathode on the side opposite the anode, for example, the material corresponding to the anode may be a copper plate including copper, and the material corresponding to the cathode may be a plate including magnesium.

[0088] In one embodiment, the switch 220 may be in direct contact with the portions of the light emitting portion 240 that correspond to the cathode and anode.

[0089] In one embodiment, the switch 220 can be located on the outer surface of the body 210, and the structure, position, shape, etc. of the switch 220 are not limited to those illustrated in the drawings.

[0090] In one embodiment, the cover 230 includes a first connection terminal 232 corresponding to the cathode and a second connection terminal 233 corresponding to the anode, and the first connection terminal 232 and the second connection terminal 233 can be electrically connected to each other. Specifically, the first connection terminal 232 and the second connection terminal 233 can be electrically connected to the light emitting portion 240.

[0091] In one embodiment, the first connection terminal 232 and the second connection terminal 233 can be electrically connected to a battery when the cover 230 is attached to the body 210, thereby supplying power to the light emitting unit 240. Specifically, the first connection terminal 232 and the second connection terminal 233 can be coupled to the body 210 by being in contact with both sides of the switch 220, respectively.

[0092] In one embodiment, the cover (230) may include a hole (231) on one side of the cover (230) through which a hook part can pass so that the hook part can be connected to the cover (230) in a hooked manner.

[0093] For example, when a hook part or a device similar to a hook part is passed through the hole (231), the light emitting device (200) is connected to the hook part, and the user can connect the hook part connected to the light emitting device (200) in a manner that hangs it at another specific location, thereby achieving the effect of allowing the light emitting device (200) to be used while being hung at a desired location.

[0094] In one embodiment, the lighting device (200) may include a dome (250) that is removably mated to an upper end of the cover (230).

[0095] In one embodiment, the dome 250 may have a shape that covers at least a portion of the light emitting portion 240, and may be provided in various shapes and colors, such as a hemisphere, a rectangle, etc. Furthermore, the dome 250 may be made of the same material as the cover 230.

[0096] In one embodiment, the light emitting device 200 can emit various lights depending on the shape and color of the dome 250. For example, if the dome 250 is hemispherical and blue in color, a hemispherical blue light can be emitted to the outside when the light emitting device 200 illuminates the outside.

[0097] In one embodiment, the cover 230 has a groove in a portion of the cover 230 that corresponds to the dome 250, so that the dome 250 and the cover 230 can be joined in a mating manner.

[0098] In one embodiment, the function of the cover (230) when combined with the upper part of the light-emitting device (200) (controlling the illuminance of the light-emitting portion (240)) and the function of the cover (230) when combined with the lower part of the light-emitting device (200) (providing a sturdy support for the light-emitting device (200)) can be different from each other.

[0099] FIG. 3 is a diagram illustrating an example of a method for generating power for a light emitting device according to several embodiments of the present disclosure.

[0100] Referring to FIG. 3, a battery can include a power generation unit (300) that generates electricity.

[0101] In one embodiment, the power generating unit (300) may include a first layer (310) containing copper, a second layer (320) containing an active material, a third layer (330) containing a material, specifically a separator separating the cathode and anode, and a fourth layer (340) containing magnesium.

[0102] In one embodiment, the third layer (330) has a more protruding shape than the other layers and can be in a shape that directly absorbs liquid. For example, the third layer (330) can be in direct contact with the liquid or can be supplied with liquid from a liquid supply. When the third layer (330) comes in contact with the liquid and absorbs the liquid, it can facilitate the movement and passage of ions supplied from the liquid, enabling electrical actuation between the anode and cathode.

[0103] In one embodiment, when no liquid is supplied to the third layer (330), it can act as a barrier to prevent the cathode and anode from directly contacting each other.

[0104] In one embodiment, the power generating unit (330) is capable of generating an electric current when the third layer (330) is supplied with liquid, in which electrons emitted by the oxidation of magnesium in the fourth layer (340) travel through an electric wire or the like to the copper in the first layer (310) and reduce the copper.

[0105] In one embodiment, the second layer (320) can be activated carbon, which can be used as an electrochemical catalyst in some forms of batteries and fuel cells, for example, to promote a reaction between electrons and oxygen to produce electrical energy.

[0106] In one embodiment, the second layer 320 can also provide structural support to the electrode material. For example, activated carbon can be used in conjunction with the electrode material to increase the stability of the electrode and better hold the particles of the electrode material together.

[0107] In one embodiment, the second layer (320) can act as a support for an electrolyte separator membrane, providing separation and electrical communication between the electrolyte and the electrodes.

[0108] In one embodiment, the second layer 320 may be used to adhere to an electrode material in a battery to improve active material dispersion or improve electrode performance.

[0109] In one embodiment, the electrons may travel along the direction of the arrow 350, and the path along which the electrons travel may be electrically connected to a power consuming device 360. For example, the power consuming device 360 ​​may correspond to a light emitting unit.

[0110] FIG. 4 is a diagram illustrating another example of a method for generating power for a light emitting device according to several embodiments of the present disclosure.

[0111] In one embodiment, the battery 400 can be configured such that multiple power generation units 410 are coupled in series and / or parallel.

[0112] In one embodiment, when the battery 400 is configured with a power generation unit 410 having only one layer, the power is generated at a voltage of 1.5 to 1.6 V per unit area (cm 2 ) can be discharged at 5 mA per 100 mA. In this case, in one embodiment, if n power generation units 410 are connected in series to the battery 400, the voltage can be n times 1.5 to 1.5V.

[0113] In one embodiment, when the power generating unit (410) consists of a single layer, when 1 to 2 ml of liquid is steadily supplied, the light emitting section can generate enough power to emit light for 168 hours.

[0114] In one embodiment, when the power generating unit (410) consists of one layer, when 1 ml of liquid is supplied, the light emitting part can maintain maximum brightness for about 10 hours, and when the brightness of the light emitting part decreases after 10 hours, the maximum brightness can be maintained by supplying the same amount of liquid again.

[0115] In one embodiment, the battery 400 can be replenished with magnesium to allow for repeated or continuous use.

[0116] In one embodiment, the battery 400 uses liquid, which provides the advantage of being free of fire risks and hazards.

[0117] In one embodiment, the battery 400 has the advantage that it can be stored for up to 10 years or more if no liquid is provided.

[0118] The lighting device (200) according to an embodiment allows for easy dispensing of liquid via user input, improving the user experience in using the lighting device (200).

[0119] The light emitting device (200) according to one embodiment utilizes a plurality of sensors, which not only automates the operation of the light emitting device (200) but also ensures the stability of the operation of the light emitting device (200).

[0120] FIG. 5 is an exploded perspective view illustrating the structure of a light emitting device according to several embodiments of the present disclosure.

[0121] Referring to FIG. 5, in yet another embodiment, the lighting device includes a body (1110), a battery (1120), a lighting unit (1130) and a dome (1140).

[0122] In one embodiment, the body (1110) has an accommodation space (1111) with an open upper side formed therein for accommodating the battery (1120), a liquid inlet (1112) for supplying liquid to the accommodation space (1111) formed at the lower end, and exposure grooves (1113) for exposing the magnesium negative electrode plate (1121) and the positive electrode current collector plate (1124) of the battery (1120) formed on both sides of the upper end. In the drawings of this embodiment, the body (1110) is shown as having a rectangular pillar shape, but is not limited to this example and may have various shapes as necessary.

[0123] In one embodiment, the liquid inlet 1112 may have a shape that opens at the bottom of the storage space 1111 so that a large amount of liquid can be supplied to the storage space 1111 in a short time. In addition, protrusions 1114 that can support the bottom of the battery 1120 may be provided on both sides of the liquid inlet 1112 in order to prevent the battery 1120 housed in the storage space 1111 of the main body 1110 from being pulled out by the liquid inlet 1112.

[0124] In addition, on both inner wall surfaces in contact with the storage space (1111), pressure projections (1115) extend vertically to apply pressure to the battery (1120) housed in the storage space (1111) in the stacking direction. A plurality of such pressure projections (1115) can be provided and spaced apart from each other along the width direction of the battery (1120). This makes it possible to uniformly pressurize the battery (1120) housed in the storage space (1111) of the main body (1110) as a whole, which leads to improved power generation efficiency of the battery (1120).

[0125] In one embodiment, the battery (1120) is in the form of a laminate of a magnesium negative electrode plate (1121), a separator (1122), an oxygen absorbing layer, and a positive current collector plate (1124).

[0126] In one embodiment, referring to FIG. 3, a magnesium negative electrode plate (1121) can correspond to the fourth layer (340), a separator (1122) can correspond to the third layer (330), an oxygen absorbing layer can correspond to the second layer (320), and a positive electrode current collector (1124) can correspond to the first layer (310).

[0127] In one embodiment, the magnesium cathode plate (1121) may be made of magnesium or magnesium alloys such as AZ31, AZ61, AZ91, and the like.

[0128] In one embodiment, the oxygen adsorbing layer can include, as the positive electrode active materials, activated carbon that adsorbs oxygen from the air, polyvalent carboxylates, manganese, and metal powders.

[0129] In one embodiment, the separator (1122) is disposed between the magnesium cathode plate (1121) and the oxygen adsorption layer, allowing the passage of ions and separating the magnesium cathode plate (1121) from the oxygen adsorption layer. The separator (1122) is made of polypropylene fiber, glass fiber, filter paper, etc., has insulating properties and high liquid absorption properties, is provided in a dry state, and is capable of retaining absorbed liquid during use.

[0130] In one embodiment, the anode current collector 1124 is made of a conductor and connects to the oxygen adsorbent layer to provide electrons to the oxygen adsorbent 1123. The anode current collector can be made of a metal such as copper.

[0131] In one embodiment, the magnesium negative electrode plate (1121), separator (1122), oxygen absorption layer, and positive electrode current collector plate (1124) are preferably stacked in order and in close contact with each other. Since the current increases as the contact area increases, the contact area can be adjusted according to the required current capacity. Depending on the required voltage, multiple batteries (1120) can be stacked in the thickness direction and connected in series.

[0132] In one embodiment, the battery (1120) is configured such that when liquid is supplied to the separator (1122) and the oxygen adsorption layer, the magnesium negative electrode plate (1121) generates magnesium ions (2Mg → 2Mg 2+ 4e), the oxygen adsorption layer adsorbs and reduces oxygen in the air, generating hydroxide liquid ions (O2 + 2H2O + 4e → 4OH - The detailed structure and operating principle of the battery are well known, so a detailed description of these will be omitted. (Metal-air batteries: from oxygen reduction electrochemistry to cathode catalysts, F. Cheng et al., Chem. Soc. Rev., 2012, 41, 2172-2192)

[0133] In one embodiment, the battery (1120) accommodated in the accommodation space (1111) of the body (1110) has an exposure groove (1113) on one side of the upper end of the body (1110) that exposes a magnesium cathode plate (1121), which is the cathode, and an exposure groove (1113) on the other side that exposes a cathode collector plate (1124), which is the anode.

[0134] In one embodiment, the battery (1120) has an operating voltage of 1.5 to 1.6 V (one battery (1120)) and a medium discharge rate (~5 mA / cm 2 ) and because the electrolyte is salt water, it is easy to handle, there is no risk of fire, and it can be stored for long periods without a supply of liquid. Although it cannot be recharged, it can be used continuously by refilling the magnesium cathode plate (1121) and electrolyte, and it has the advantage that electricity can be produced for more than 168 hours with a small amount of liquid (1 to 2 ml).

[0135] In one embodiment, the light emitting unit (1130) is disposed at the upper end of the body (1110) and provides illumination by receiving electricity generated by the battery (1120). The light emitting unit (1130) includes a cover (1131) that is removably assembled to the upper end of the body (1110), a light emitting part (1132) that is fixed to the upper surface of the cover (1131), and a pair of connection terminals that are electrically connected to the light emitting part (1132) and can be connected to the magnesium cathode plate (1121) and anode collector plate (1124) of the battery (1120), respectively.

[0136] In one embodiment, the cover (1131) has a receiving groove (1131a) formed on the bottom surface thereof, which can be coupled to one side and the other side of the upper end of the body (1110), and protrusions (1131b) that can be inserted into the exposed groove (1113) of the body (1110) are formed on the inner wall surfaces on both sides in contact with the receiving groove (1131a). For example, the upper end of the body (1110) may have a rectangular cross-sectional shape, and the receiving groove (1131a) may have a rectangular cross-sectional shape that can receive the upper end of the body (1110).

[0137] In one embodiment, the light-emitting portion (1132) may be formed of a light-emitting diode (LED), and the pair of connection terminals comprises a first connection terminal (1133) connected to the cathode terminal of the light-emitting portion (1132) and arranged on the protrusion (1131b) on one side of the cover (1131) that contacts the accommodating groove (1131a), and a second connection terminal (1134) connected to the anode terminal of the light-emitting portion (1132) and arranged on the protrusion (1131b) on the other side of the cover (1131) that contacts the accommodating groove (1131a).

[0138] In other words, when the cover (1131) is attached to the upper end of the body (1110) in one direction, the first connection terminal (1133) connected to the cathode of the light-emitting part (1132) is connected to the magnesium cathode plate (1121), and the second connection terminal (1134) connected to the anode of the light-emitting part (1132) is connected to the anode current collector plate (1124), so that the light-emitting part (1132) emits light to provide illumination, When the cover (1131) is attached to the upper end of the main body (1110) in the other direction, the first connection terminal (1133) connected to the cathode of the light-emitting section (1132) is connected to the anode current collector plate (1124), which is the anode, and the second connection terminal (1134) connected to the anode of the light-emitting section (1132) is connected to the magnesium cathode plate (1121), which is the cathode, so that the light-emitting section (1132) does not emit light.

[0139] Therefore, even while liquid is being supplied to the battery (1120) to produce electricity, it is possible to determine whether the light-emitting unit (1130) is turned on or off depending on the assembly direction of the cover (1131), such as by assembling the cover (1131) in one direction when illumination is needed, and by assembling the cover (1131) in the other direction when illumination is not needed.

[0140] Meanwhile, although not shown in the drawings, in one embodiment, the pair of exposed grooves (1113) may be asymmetrically disposed on both sides of the body (1110), and the pair of connection terminals may also be asymmetrically disposed to correspond to the positions where the exposed grooves (1113) are formed. In this case, the pair of connection terminals are connected to the magnesium cathode plate (1121) and the anode current collector plate (1124) only when the cover (1131) is coupled to the upper end of the body (1110) in one direction, and in the opposite case, the connection terminals are not connected to the magnesium cathode plate (1121) and the anode current collector plate (1124).

[0141] In one embodiment, the dome (1140) is made of a translucent material, includes a light diffusion layer capable of diffusing illumination light provided from the light-emitting portion (1132), and is configured to be removably assembled to the upper side of the cover (1131).

[0142] In one embodiment, the light diffusion layer can be made of a milky white pigment or dye contained in a light-transmitting resin, and can have a light diffusion structure of various types, such as forming beads or pores for light diffusion in the light-transmitting resin, or forming fine irregularities on the surface for light diffusion.

[0143] Meanwhile, a coupling groove (1131c) is formed on the upper surface of the cover (1131) to which the lower end of the dome (1140) can be coupled. The coupling groove (1131c) preferably provides a coupling force sufficient to prevent the dome (1140) from being accidentally separated when the lower end of the dome (1140) is inserted, and to allow the user to separate the dome (1140) from the coupling groove (1131c) by pulling the dome (1140) in the separation direction as necessary. It is also possible to arrange a permanent magnet instead of the coupling groove (1131c) on the upper surface of the cover (1131) and arrange a permanent magnet or a magnetic material that can be attached to the permanent magnet on the lower end of the dome (1140) so that the coupled state of the dome (1140) and the cover (1131) is maintained by magnetic force.

[0144] Therefore, when a user needs bright illumination from the light-emitting portion (1132), the user can use the dome (1140) separated from the light-emitting unit (1130), and when a user needs soft illumination such as mood lighting, the user can use the dome (1140) connected to the light-emitting unit (1130).

[0145] FIG. 6 is a cross-sectional view illustrating a side and plan structure of a light emitting device according to multiple embodiments of the present disclosure.

[0146] The magnesium cathode plate (1121), separator (1122), oxygen absorber (1123) and anode current collector (1124) constituting the battery (1120) are accommodated in the storage space (1111) inside the body (1110) in a stacked state in order, and the magnesium anode plate (1121) and anode current collector (1124) arranged at both ends of the battery (1120) are exposed to the outside through exposure grooves (1113) formed on both sides of the upper end of the body (1110).

[0147] In one embodiment, a cover (1131) of the light-emitting unit (1130) can be removably assembled to the upper end of the main body (1110), and when the cover (1131) is assembled, a first connection terminal (1133) connected to the cathode of the light-emitting part (1132) can be connected to the magnesium cathode plate (1121), and a second connection terminal (1134) connected to the anode of the light-emitting part (1132) can be connected to the anode collector plate (1124).

[0148] However, in one embodiment, the battery 1120 does not produce electricity unless liquid is supplied to the separator 1122 and the oxygen absorber 1123. Therefore, since the light emitting part 1132 does not light up just by assembling the cover 1131 of the light emitting unit 1130 to the upper end of the main body 1110 and electrically connecting the light emitting part 1132 to the battery 1120, the light emitting part 1132 can be stored and distributed for long periods of time in the state in which the light emitting unit 1130 is assembled to the main body 1110.

[0149] In one embodiment, when liquid is supplied to the liquid inlet (1112) formed at the lower end of the main body (1110), the battery (1120) generates electricity, which causes the light-emitting unit (1132) connected to the magnesium cathode plate (1121) and anode collector plate (1124) of the battery (1120) via the first connection terminal (1133) and the second connection terminal (1134) to emit light, thereby providing illumination.

[0150] According to this embodiment, a large number of pressure protrusions (1115) formed on the inner wall surfaces on both sides of the main body (1110) that contact the storage space (1111) compress the battery (1120) evenly along the stacking direction, thereby increasing the contact area of ​​the magnesium cathode plate (1121), separator (1122), oxygen absorber (1123) and anode collector plate (1124) that make up the battery (1120), thereby further improving the power generation efficiency of the battery (1120).

[0151] In one embodiment, after liquid is supplied to the battery (1120) through the liquid inlet (1112) of the body (1110), the battery (1120) continues to produce electricity, so the light emitting unit (1132) needs to be controlled to be on / off depending on whether illumination is required or not. However, when the cover (1131) is separated from the body (1110), there is a risk that the battery (1120) accommodated in the accommodation space (1111) inside the body (1110) may come off to the outside, so it is preferable to keep the cover (1131) attached.

[0152] Therefore, in this embodiment, the cover (1131) is adapted to be connected to the main body (1110) in one side direction and the other side direction, respectively, so that the on / off of the light-emitting unit (1132) can be controlled depending on the connecting direction of the cover (1131).

[0153] FIG. 7 is a diagram for explaining the operation of a light emitting device according to several embodiments of the present disclosure.

[0154] Specifically, when the upper end of the main body (1110) and the cover (1131) are connected in one direction as shown in (a) of FIG. 7, the first connection terminal (1133) connected to the cathode of the light-emitting part (1132) is connected to the magnesium cathode plate (1121), which is the cathode of the battery (1120), and the second connection terminal (1134) connected to the anode of the light-emitting part (1132) is connected to the anode collector plate (1124), which is the anode of the battery (1120), so that the light-emitting part (1132) emits light to provide illumination.

[0155] On the other hand, when the upper end of the main body (1110) and the cover (1131) are connected in the other direction as shown in (b) of Figure 7, the first connection terminal (1133) connected to the cathode of the light-emitting part (1132) is connected to the anode collector plate (1124), which is the anode of the battery (1120), and the second connection terminal (1134) connected to the anode of the light-emitting part (1132) is connected to the magnesium cathode plate (1121), which is the cathode of the battery (1120), so that the light-emitting part (1132) does not emit light.

[0156] In one embodiment, while liquid is being supplied to the battery (1120) to generate electricity, the on / off state of the light-emitting unit (1130) can be determined depending on the assembly direction of the cover (1131), such as by assembling the cover (1131) in one direction if illumination is needed, and by assembling the cover (1131) in the other direction if illumination is not needed.

[0157] FIG. 8 is a cross-sectional plan view of a light emitting device according to several embodiments of the present disclosure.

[0158] As shown in FIG. 8, one embodiment of the present invention differs in configuration from other embodiments in that additional pressure members (1150) are arranged on both sides of the storage space (1111) of the main body (1110) to pressurize the battery (1120) in the stacking direction.

[0159] In one embodiment, the pressure member (1150) can be made of an elastic material bent into a wave-like shape and arranged with alternating convex and concave portions, each of which functions as a pressure protrusion (1115'), thereby more effectively compressing the battery (1120) along the stacking direction while providing uniform pressure over the entire area.

[0160] The pressure member (1150) can be in the form of a leaf spring that can be compressed and expanded in its thickness direction, or it can be in the form of a moisture-absorbing expansion member that expands and increases in volume by absorbing liquid, or the like.

[0161] On the other hand, although not shown in the figures, the pressure applied by the pressure member to the battery (1120) in the stacking direction may be weaker at the center of the pressure surface than at both ends. Therefore, it is preferable to set the thickness of the center portion of the pressure member to be thicker than the thickness of both ends so that the pressure member can provide an overall uniform pressure force to the battery (1120).

[0162] FIG. 9 is a diagram for explaining an example of a light emitting device including a whistle portion according to several embodiments of the present disclosure.

[0163] FIG. 9 discloses a whistle unit (10A) that is provided on one side of a light emitting device and generates sound by injecting air.

[0164] In one embodiment, the whistle unit (10A) may include an air inlet unit (20A) including an air passage for air to flow in, and a sound generating unit (30A) that generates sound by receiving air from the air inlet unit (20A). The whistle or whistle unit in the present disclosure may refer to a structure that amplifies sound by changing the amount of air at regular intervals. As an example, the whistle or whistle unit may be operated by injecting outside air into a portion of the light-emitting device. The above-mentioned outside air may be generated by the user's breath, as an example.

[0165] In one embodiment, a user of the light emitting device injects air through the air injection section (20A), and the injected air passes through the air injection section (20A) and enters the sound generation section (30A), causing a resonance phenomenon, thereby generating sound.

[0166] In one embodiment, the specifications regarding the length, area, volume, etc. of the air injection part (20A) and the sound generation part (30A) are not limited. For example, the horizontal length of the air injection part (20A) and the sound generation part (30A) may be the same as the length of one side of the light emitting device, and the vertical length may be approximately 1 cm and 2 cm, respectively.

[0167] In one embodiment, the sound generating portion 30A can be integrally injected into the main body during the process in which the light emitting device is manufactured.

[0168] In one embodiment, the air injector 20A can be injected separately from the body during the manufacturing process of the light emitting device.

[0169] In one embodiment, the sound generating unit (30A) can be injected using the same material as the main body, and the air injection unit (20A) can be made of the same material as the sound generating unit (30A) or a different material than the sound generating unit (30A), and the materials are not limited.

[0170] In one embodiment, the sound generating unit (30B) is fixed to the light emitting device, and the air injecting unit (20B) can be a separate structure from the sound generating unit (30B) that is separable from the light emitting device.

[0171] In one embodiment, the air injector 20B can be separated or attached by sliding it on the light emitting device.

[0172] In one embodiment, the light emitting device may include a guide portion (21B) in a portion of the whistle portion (10B) so that the air injection portion (20B) can slide.

[0173] In one embodiment, the sound generating section (30B) can include an opening (31B) through which air flows in, on a surface that the air injecting section (20B) slides and contacts.

[0174] In one embodiment, the surface facing the opening (31B) is closed, so that the air that has flowed in through the opening (31B) can be discharged again through the opening (31B).

[0175] In one embodiment, the opening 31B may have a groove shape so that when the air injection part 20B completely slides and contacts the sound generating part 30B, the air flowing in through the opening 31B passes through and flows out from a place other than the air injection part 20B. For example, since the opening 31B has a groove shape, the surface of the opening 31B may be formed such that the surface of the opening 31B that contacts the sound generating part 30B forms an angle with the surface of the sound generating part 30B that is not parallel.

[0176] FIG. 10 is a diagram illustrating an air injection section of a whistle according to several embodiments of the present disclosure.

[0177] Referring to FIG. 10, the air injecting section (20C) may include an air passage (23C) whose upper surface has a gently curved shape.

[0178] In one embodiment, a bridge 22C may be included at the bottom of the air passage 23C so that the air inlet 20C can be connected and / or separated in a sliding manner while connected to the light emitting device.

[0179] In one embodiment, the air injection portion (20C) may include a protrusion (24C) for securing the air injection portion (20C) to the light emitting device so that the air injection portion (20C) cannot be separated from the light emitting device in any manner other than a sliding manner.

[0180] In one embodiment, when the air injection section (20C) is viewed from the front, the air passage (23C) is located on the upper side of the air injection section (20C), one bridge (22C) is provided on each of both side surfaces of the air injection section (20C), and each of the two bridges (22C) may be provided with a protrusion (24C) facing toward the inside of the air injection section (20C).

[0181] In one embodiment, the length by which the protrusion 24C protrudes from the bridge 22C may be 1 to 2 mm.

[0182] In one embodiment, the air injection part 20D may include a coupling part 21D so that it can slide and couple with the sound generating part 30B.

[0183] In one embodiment, when the air injecting portion (20D) is viewed from the side, the coupling portion (21D) may correspond to a structure in which a portion of one side of the air injecting portion (20D) is recessed.

[0184] In one embodiment, the connecting portion (21D) may be included in the bridge (22C) of the air injection portion (20D).

[0185] FIG. 11 is a diagram illustrating a sound generating portion of a whistle according to several embodiments of the present disclosure.

[0186] According to FIG. 11, the sound generating section (30C) can include a resonance section (32C) that changes the flow of air that has flowed in through the opening (31B).

[0187] In one embodiment, the resonating portion (32C) may have a structure that is configured to generate a resonance phenomenon and generate sound when air flows in through the opening (31B) and is discharged again through the opening (31B).

[0188] In one embodiment, a user of the lighting device can slide and fix the air injection section (20D) to a desired position, and allow air to flow through the air injection section (20D) and the opening (31B) into the resonator section (32C).

[0189] In one embodiment, the sound generating portion (30C) may include a stepped portion (33C) that corresponds to the coupling portion (21D) of the air injection portion (20D) and allows the sound generating portion (30C) to couple with the air injection portion (20D).

[0190] For example, when the air injection section (20D) slides and comes into contact with the sound generating section (30C), the connecting section (21D) and the step section (33C) come into contact with each other, thereby preventing the air injection section (20D) from sliding any closer to the sound generating section (30C).

[0191] In one embodiment, the contact between the connecting portion (21D) and the step portion (33C) increases the contact area between the air injection portion (20D) and the sound generating portion (30C), thereby enabling the air injection portion (20D) to be more stably fixed to the sound generating portion (30C).
