Description

TECHNICAL FIELD

[0001] The present application relates to an ion wind generating and accelerating device and a high-visibility sign device and a lighting device using the same, and more particularly, to an ion wind generating and accelerating device and a high-visibility sign device and a lighting device having the same, in which the ion wind generating and accelerating device generates and accelerates ion wind to be sprayed toward the front of a visibility object, so that ions of the ion wind settle suspended foreign matters in the front of the visibility object to improve the visibility of the visibility object. BACKGROUND

[0002] Ion wind generated by plasma discharge is generated by ions generated at a discharge electrode moving toward a ground electrode under the action of a Coulomb force. That is, the moving ions collide with air molecules to push the air molecules in the same direction to move, and this movement of the air molecules is ion wind. In order to generate stronger ion wind, it is necessary to accelerate the generated ions to high speed while generating more ions.

[0003] Figure 1 is a diagram for explaining the principle of generation of ion wind.

[0004] As shown in Figure 1 , if a high voltage (HV) is applied to a needle electrode as a discharge electrode, plasma is generated in the vicinity of the needle electrode due to a strong electric field. The ions generated by the plasma discharge move toward a cylindrical electrode as a ground electrode and collide with the surrounding air molecules to release outer electrons of the air molecules, thereby separating into ions and free electrons. At this time, the generated free electrons repeatedly the same process in a chain to cause an electron avalanche phenomenon in which a large number of electrons and ions are generated in the plasma discharge region.

[0005] The ions generated by the above process push the surrounding air molecules that are electrically neutral while moving toward the cylindrical electrode. The air pushed by the ions receives kinetic energy of the ions, and a part of the air moves by friction with the ions and passes through the cylindrical electrode. The air molecules passing through the cylindrical electrode are ion wind.

[0006] In addition, hydroxyl (OH) radical ions have an effect of purifying air by sterilizing microorganisms or viruses suspended in air, reducing fine dust, and removing odor, and thus are widely used in air purifiers.

[0007] Further, the ion wind has a property of neutralizing and settling smoke and toxic gas, ultrafine dust, soot, black smoke, harmful gas generated at the time of combustion, and particulate matter, etc. generated at the time of fire. If the ion wind is used, the visibility of the rescuer is secured at the time of fire, so that rapid escape can be guided.

[0008] As background art related thereto, Korean Domestic Publication Patent Gazette No. 10-2023-0006751 (Lifting Type Ion Wind Air Purifier) is disclosed.

[0009] The disclosed air purifier is a lifting type ion wind air purifier including an emitter generating electric charges by corona discharge, a plurality of collectors disposed above the emitter and spaced apart from each other and generating ion wind when a power source is applied, a non-trapping portion disposed in plurality and alternately disposed with the collectors and allowing charged particles to be gathered in the collectors, and a housing for mounting the emitter, the collectors, and the non-trapping portion and located at an upper portion of a ceiling or a wall of an indoor space, i.e., a mounting site, the above air purifier allowing the housing to be lifted between a site having a predetermined height from the ground and the mounting site.

[0010] On the other hand, it is well known that if a fire occurs in a building, the indoor space is in a dark state due to power failure, and even a marking device indicating the direction of an emergency exit is hidden from view by smoke and toxic gas. Even in an emergency, as long as there is a high-visibility marking device indicating an emergency escape exit, it is possible to somewhat reduce the number of casualties.

[0011] However, in the case of the existing marking device (various induction lights), even if the illuminance is high, it is not seen due to the thick black smoke and toxic gas blocking the light. Only by quickly securing the visibility of the marking device by removing the harmful gas and particulate matter generated at the time of combustion that hide the marking device (various induction lights), it is possible to save even one life. That is, a technology for removing suspended combustion by-products (soot, black smoke, ultrafine dust, etc.) and securing a visible distance is required. SUMMARY

[0051] Hereinafter, an embodiment according to the present application will be described in more detail with reference to the accompanying drawings.

[0052] ​​​​​​The ion wind generating and accelerating device of the present embodiment accelerates the ion wind formed by the plasma discharge to be widely diffused into the air, thereby being able to remove the contaminated substances in the air, and thus functioning not only at the time of fire but also at ordinary times.

[0053] As for the various "induction lights and lighting devices", how well the light transmits the fine dust, soot, smoke, suspended substances at the installation site at ordinary times is a very important core element.

[0054] As for the various "induction lights and lighting devices", how well the light transmits the fine dust, soot, smoke, suspended substances at the installation site at ordinary times is a very important core element.

[0055] In particular, the ability to neutralize the ions possessed by the harmful gases and particulate substances such as smoke and toxic gases generated at the time of fire, ultrafine dust, soot, black smoke, smoke particles, and the like generated at the time of combustion, and to settle to the ground, thereby greatly improving the visibility of the emergency escape marking device in the case of being applied to the marking device for emergency escape, is provided. The so-called "improvement of visibility" means being conspicuous in the emergency situation at the time of fire. Even if the person in need of rescue can only see the marking device, the mortality rate can be greatly reduced.

[0056] In addition, at ordinary times, the ultrafine dust in the room and the external inflow of yellow sand and the like are neutralized and settled to the ground to purify the air, thereby maintaining a clear visual environment to make the emergency exit induction light clearly visible, and providing fresh air.

[0057] The above-described marking device can be installed at a place including the emergency escape passage or emergency escape exit, door frame, staircase, corridor, ceiling, side wall, floor, and the like of various buildings, underground parking lots, and special facilities, various tunnels, large ships, subways, factories, large warehouse-type shopping malls, public facilities, and the like, and can also be manufactured and applied in any shape.

[0058] Figure 2a is a block diagram showing the operation mode of a high-visibility marking device 20 having an ion wind generating and accelerating device according to one embodiment of the present application.

[0059] As shown in the drawing, the high-visibility marking device 20 according to the present embodiment includes a power supply 10, a marking portion 30, and an ion wind generating and accelerating device 60.

[0060] The power supply 10 supplies power for driving the marking device 20, and includes a commercial power supply 11, an emergency power supply 12, and a hydroelectric generator 13.

[0061] Commercial power supply 11 supplies electricity under normal conditions, while emergency power supply 12 operates during power outages due to fire or other reasons. Additionally, a hydroelectric generator 13 is installed on the fire-fighting water pipeline through which fire-fighting water flows. Figure 3 (Ref. 14) The hydroelectric generator 13 is a device that receives the kinetic energy of fire-fighting water to generate electricity. If the sprinkler system is activated during a fire, the hydroelectric generator 13 also automatically operates to generate electricity. Matters related to the hydroelectric generator installed in the fire-fighting water pipeline are disclosed in Korean Patent No. 10-2485464, applied for and granted by the inventor of this invention.

[0062] The signage unit 30 includes a light output unit and a display unit 21. The light output unit is a surface light source unit 34 or an LED light 33 with a built-in fluorescent lamp or special lamp. A related description will be given later. The display unit 21 is the part that displays the signage content. The display unit 21 is the visual object that comes into view (visual recognition); for example, it can be like… Figure 8 , Figure 9 , Figure 11 As shown, this can be achieved through text, arrow images, or other specific means.

[0063] The ion wind generating and accelerating device 60 generates ion wind and diffuses it in front of the display unit 21. The reason for diffusing the ion wind in front of the display unit 21 is to neutralize and cause the pollutants in front of the display unit to settle, as the ion particles constituting the ion wind are present. Additionally, this is done to improve the visibility of the display unit.

[0064] The ion wind generating and accelerating device 60 includes an ion wind generating unit 40 and an ion wind inducing unit 50. The ion wind generating unit 40 generates ion wind, and the ion wind inducing unit 50 accelerates and diffuses the generated ion wind and induces it to the front of the display unit 21.

[0065] Figure 2b This is a block diagram illustrating the operation of a high-visibility lighting device 80 with an ion wind generating and accelerating device according to an embodiment of the present invention.

[0066] The high visibility lighting device 80 has a lighting lamp 46 instead of Figure 2a 30. Signage section. Lighting ( Figure 13 and Figure 14 Reference numeral 46) is a lamp that illuminates the interior space, packaged together with an ion wind generating and accelerating device 60. The ion wind is directed in front of the lamp 46 to improve its visibility. In the event of a fire, the lamp also serves to indicate escape routes, thus the lamp 46 can also be considered a visually perceptible object.

Further, Figure 7 is a diagram for explaining the ion wind acceleration principle in the ion wind generating and accelerating device shown in Figure 6

[0068] Figure 3 The identification device 20 shown in

[0069] The water turbine 13 is installed to a fire-fighting water pipe 14, and is a power source that generates electric power by receiving kinetic energy of fire-fighting water passing through the fire-fighting water pipe 14. Part of the electric power of the water turbine 13 is transmitted to the identification section 30 through a power line 16, and the remaining electric power is supplied to the high voltage generator 41.

[0070] The identification section 30 is a visual recognition object including a substrate plate 31 and a plurality of LED lamps 33 as light output sections. In the present embodiment, although the LED lamps 33 are exemplified, other kinds of lamps known in the art can be applied in addition to the LED lamps 33.

[0071] The substrate plate 31 is a flat plate member having an arrow shape, and is connected to the water turbine 13 through the power line 16. A circuit for driving the LED lamps 33 is installed to the substrate plate 31.

[0072] Further, the LED lamps 33 are arranged following the shape of the substrate plate 31. An imaginary straight line connecting the LED lamps 33 has an arrow shape as a whole. The LED lamps 33 guide a direction in a lighted state. For example, a fire escape route is indicated, so that people can escape along the direction indicated by the LED lamps 33 at the time of fire.

[0073] As for the identification section 30 having the above-described configuration, although the shape of the arrow is provided, the shape or size of the identification section can be changed. Further, the installation position of the identification device 20 can be variously selected.

[0074] The reference numeral 31a is a spacer. The spacer 31a plays a role of maintaining the interval of the discharge electrode plate 43 with respect to the substrate plate 31.

[0075] ​The high voltage generator 41 outputs high voltage power for plasma discharge using electric power applied from the hydroelectric generator 13. The high voltage power output from the high voltage generator 41 is transmitted to the discharge electrode plate 43 through the electric power line 42.

[0076] The discharge electrode plate 43 is an arrow-shaped plate-like material that provides a support force, and supports a plurality of electrode members 44. The discharge electrode plate 43 is smaller in size than the substrate plate 31 so as to expose the LED lamp 33 to the front. The discharge electrode plate 43 is arrow-shaped because the logo portion 30 is arrow-shaped and the LED lamps 33 as light output portions are arranged in an arrow shape. In other words, the discharge electrode plate 43 has an arrow shape in order to maximize the proximity of the electrode members 44 to each of the LED lamps 33. The electric power line 42 and a circuit (not shown) that connects the electrode members 44 are installed inside the discharge electrode plate 43.

[0077] A plurality of spacers 43a are also fixed to the discharge electrode plate 43. The spacers 43a function to maintain the interval of the acceleration plate 53 with respect to the discharge electrode plate 43.

[0078] The electrode members 44 are installed to the front surface of the discharge electrode plate 43, and are internally connected to the high voltage generator, and ionize the surrounding air through plasma discharge to generate ion wind. The electrode members 44 in the present embodiment are needle-shaped (ACICULAR) electrodes having a sharp shape at the front end portion. The electrode members 44 are arranged so that the center axis passes through the center portion of the Venturi hole 53a. The electrode members 44 can be made in a BAR type in addition to the needle type. In addition, a carbon brush can be made to increase the amount of air ionization.

[0079] The discharge electrode plate 43 and the plurality of electrode members 44 constitute an ion wind generation portion 40 that generates ion wind. The ion wind generated in the ion wind generation portion 40 is accelerated and diffused by the ion wind induction unit 50 to be diffused to the front of the logo device 20, thereby improving the visibility of the LED lamp 33.

[0080] The ion wind induction unit 50 functions to accelerate and diffuse the ion wind generated by the ion wind generation portion, and for this purpose has a magnet and an acceleration plate 53.

[0081] The magnet includes a first magnet 51 and a second magnet 52. The first and second magnets 51, 52 are neodymium magnets that adopt a ring shape, and output the same magnetic force. However, the magnetic force of the first magnet 51 and the second magnet 52 can be different. In the present embodiment, the first and second magnets 51, 52 are embodied in a ring shape, but the shape or size of the first and second magnets 51, 52 can be variously deformed.

[0082] As Figure 6 or Figure 7As shown, the first magnet 51 is fixed to the discharge electrode plate 43 in a state of surrounding the electrode member 44. Further, the second magnet 52 is installed to the acceleration plate, and has the same inner diameter as the Venturi hole 53a. A part of the Venturi hole 53a is the second magnet.

[0083] The first magnet 51 and the second magnet 52 are arranged to correspond one-to-one across the electrode member 44, and form a magnetic tunnel 101. The magnetic tunnel 101 accelerates ions around the electrode member 44 to pass through the Venturi hole 53a at high speed. The reason for accelerating the ions is to send the ions further.

[0084] The acceleration plate 53 is a plate-shaped member arranged apart from the discharge electrode plate 43 across the electrode member 44, and has a plurality of Venturi holes 53a. The Venturi hole 53a is a hole corresponding one-to-one to each electrode member 44 and through which the center axis of the electrode member passes. Further, as mentioned earlier, the second magnet 52 is installed to the acceleration plate 53, and the second magnet 52 constitutes a part of the Venturi hole 53a.

[0085] An inflow portion 53c, an acceleration portion 53d, and an outflow portion 53e are formed on the inner peripheral surface of the Venturi hole 53a. The inflow portion 53c is a portion that receives the ion wind, and the acceleration portion 53d is a portion that accelerates the ion wind that has passed through the inflow portion. Further, the outflow portion 53e is a portion that diffuses the ion wind that has passed through the acceleration portion. Meanwhile, a part of the inflow portion 53c and the acceleration portion 53d is the inner peripheral surface of the second magnet 52.

[0086] The ion wind that has passed through the Venturi hole 53a is accelerated because the inner diameter of the acceleration portion 53d located at the center of the Venturi hole 53a is smaller than the inner diameters of the inflow portion 53c or the outflow portion 53e. This is itself an application of the Venturi principle. Further, the outflow portion 53e has a shape that widens toward a direction away from the acceleration portion, and thus the ion wind that has passed through the acceleration portion 53d diffuses while passing through the outflow portion 53e.

[0087] As a result, the ion wind 103 that has been accelerated once by the magnetic tunnel 101 is further accelerated and diffused when passing through the Venturi hole 53a, and thus the ion wind 103 can diffuse into the air and reach further. The farther the ion wind reaches, the wider the range of suspended matter purification, and thus the visibility improvement effect is increased.

[0088] In the Figure 3 , a hydroelectric generator 13 is illustrated as a power source for driving the identification device 20, but the identification portion 30 and the ion wind generation and acceleration device 60 can be connected in parallel to a commercial power source or an emergency power source and operated as follows: in a normal state, the commercial power source is operated, and in the case where the commercial power source is powered off due to power cut in the event of a fire, the emergency power source is switched to operate, and thus normal operation is possible.

[0089] Figure 8 This is a partial cutaway perspective view illustrating another example of a high-visibility marking device 20 having an ion wind generating and accelerating device according to an embodiment of the present invention.

[0090] The same reference numerals as those in the above figures refer to the same components with the same function. Additionally, the power supply 10 is omitted from the figures.

[0091] Figure 8 The labeling device 20 shown includes a labeling unit, an ion wind generating unit, and an ion wind inducing unit.

[0092] The marking section includes a surface light source unit 34, which serves as a light output unit, and a display unit 21. The surface light source unit 34 is a module that includes a fluorescent lamp or a special lamp (not shown) and a circuit substrate for driving the fluorescent lamp or special lamp, and it is connected to the power supply 10. The surface light source unit 34 is illuminated by the power supply. The surface light source unit 34 has the shape of a generally quadrilateral plate and is located between the discharge electrode plate 43 and the acceleration plate 53.

[0093] The display unit 21 is the object of human vision (visual recognition), and it is formed on the acceleration plate 53. That is, the display unit 21 is formed on a part of the acceleration plate 53. The display unit 21 is located in front of the surface light source unit 34, and it is seen (visually recognized) by using the light output unit as a backlight. The marking content of the display unit 21 is diverse. Figure 8 In the display section 21, text and arrows are used, but in addition to text or arrows, a variety of graphics, patterns, and pictures can also be used.

[0094] in addition, Figure 8 The discharge electrode plate 43 shown is in the form of a quadrilateral plate, and has three electrode components 44 at both the upper and lower ends. Furthermore, the acceleration plate 53 is also in the form of a quadrilateral plate and covers the surface light source unit 34. The acceleration plate 53 has the same width as the discharge electrode plate 43 and is parallel to the discharge electrode plate 43 across the surface light source unit 34.

[0095] Furthermore, three Venturi holes 53a are formed at the upper and lower ends of the accelerating plate 53. The Venturi holes 53a are holes through which the ion wind generated in the electrode component 44 passes in the direction of arrow c. And, as explained above, the ion wind generated in the electrode component 44 is accelerated once by the first magnet 51 and the second magnet 52, and then undergoes secondary acceleration and diffusion when it passes through the Venturi holes 53a.

[0096] Figure 9 This is a perspective view illustrating another example of a high-visibility marking device having an ion wind generating and accelerator apparatus according to an embodiment of the present invention. Figure 10 yes Figure 9 The side view of the marking device shown.

[0097] Reference Figure 9 It can be seen that an auxiliary warning module 70 is further provided above the discharge electrode plate 43 and the acceleration plate 53. The auxiliary warning module 70 operates in emergency situations such as fires and includes a speaker 71, a flashing light 72, and an LED light 73.

Figure 12 yes Figure 11 The top view of the signage device shown. Figure 11 The signage device 20 shown is the type that is fixed to the tunnel sidewall or erected on the ground in a protruding manner, rather than fixed to the ceiling.

[0101] Figure 11 and Figure 12 The marking device 20 shown has a triangular prism-shaped discharge electrode plate 43 and an acceleration plate 53, a display unit 21, a surface light source unit 34, multiple electrode components 44, and first and second magnets 51 and 52.

[0102] The discharge electrode plate 43 is shaped like a vertically extending triangular prism and is connected to the aforementioned high-voltage generator 41. It has multiple electrode components 44 on its outer surface. The electrode components 44 receive power applied from the high-voltage generator 41 and generate an ion wind through plasma discharge. Naturally, a circuit connecting the high-voltage generator 41 and the electrode components 44 is formed inside the discharge electrode plate 43.

[0103] The accelerator plate 53 also adopts the shape of a triangular prism and extends vertically. The accelerator plate 53 houses the discharge electrode plate 43 inside. In addition, display sections 21 and multiple venturi holes 53a are formed on each surface of the accelerator plate 53. The display section 21 is the visual object that comes into view (visual recognition).

[0104] Further, a surface light source unit 34 is provided between the acceleration plate 53 and the discharge electrode plate 43. The surface light source unit 34 is lit by receiving electric power from the power source 10 and functions as a backlight of the display section 21.

[0105] Ion wind generated from the electrode member 44 is accelerated and diffused when passing through the first and second magnets 51, 52 and the Venturi hole 53a, and then diffused toward the front of the display section 21, thereby improving the visibility of the display section 21.

[0106] Figure 13 is an exploded perspective view illustrating a high visibility lighting device 80 having an ion wind generating and accelerating device according to one embodiment of the present application, Figure 14 is a view for explaining the internal configuration of the lighting device of Figure 13 .

[0107] The high visibility lighting device 80 includes a housing 36 in a quadrangular frame form, a discharge electrode plate 43, an acceleration plate 53, a light-transmissive cover 37, a lighting lamp 46, an ion wind generating section, an ion wind inducing unit.

[0108] The discharge electrode plate 43 and the acceleration plate 53 are spaced apart in parallel with the lighting lamp 46 interposed therebetween and housed in the housing 36.

[0109] Further, the light-transmissive cover 37 is a transparent plate member through which light irradiated from the lighting lamp 46 passes. The light-transmissive cover 37 can be a transparent plastic or glass. Through-holes 37a are formed at four corner portions of the light-transmissive cover 37. The through-holes 37a are holes through which ion wind passes.

[0110] The lighting lamp 46 is connected to the power source 10 and irradiates light rays by receiving electric power from the power source. Light output from the lighting lamp 46 passes through the light-transmissive cover 37 and is irradiated. The lighting lamp can be an LED lamp or a fluorescent lamp or a mercury lamp, a special lamp.

[0111] The ion wind generating section 40 includes a high voltage generator 41, the discharge electrode plate 43 which provides a supporting force, and electrode members 44 provided at four corner portions of the discharge electrode plate. The electrode members 44 are connected to the high voltage generator and ionize the surrounding air by plasma discharge to generate ion wind. Further, Venturi holes 53a are formed at four corner portions of the acceleration plate 53. The Venturi holes 53a are holes through which ion wind passes.

[0112] Ion wind generated at the electrode members 44 is accelerated when passing through a magnetic line tunnel 101 formed by the first and second magnets 51, 52, and then diffused through the Venturi holes 53a. That is, the ion wind is diffused at the front portion of the lighting device 80. The diffused ion wind neutralizes and settles suspended foreign matter at the front portion of the lighting device 80, thereby improving the visibility of the lighting device. In other words, the lighting looks more clear.
