Description

A lighting device that purifies and sterilizes indoor air

The present invention relates to a lighting fixture that has the function of purifying and sterilizing indoor air. To be more specific, the lighting function of the lighting fixture installed on the indoor ceiling is maintained while the indoor air introduced by the suction fan mounted inside the lighting fixture is As it passes through the pre-filter, pollutants such as dust contained in the indoor air are removed, and as it passes through multiple sterilizing lamps, the air is not only purified but also sterilized for bacteria and pathogens contained in the indoor air, allowing clean and fresh air into the indoor space. It can provide a comfortable living environment for residents by providing a comfortable living environment for residents, and by sterilizing germs, dust, mold, and bacteria that pollute the air and preventing their cultivation, it can greatly contribute to preventing disease and improving the health of residents. This relates to a new type of lighting fixture that has indoor air purification and sterilization functions.

A typical air purifier is equipped with a blower fan that sucks in and discharges air, and a filter with various functions on the front or back of the blower fan. The suction power of the blower fan sucks in indoor polluted air and contains it in the air through the filter. It is a mechanism that purifies indoor air by filtering out various types of dust and harmful substances and returning them back to the room.

Most of these air purifiers are installed in corners or close to walls to secure indoor space, which is by no means a desirable installation method.

In other words, due to indoor air convection, it has a cycle of being warmed as it passes through the indoor floor, then rising, cooling, and then falling. In particular, when looking at the overall flow, the rising air current is concentrated in the center of the room, rises, and cools while staying on the ceiling. It then moves toward each wall and performs a circular motion of descending to the floor along the wall.

However, as mentioned above, conventional air purifiers are installed ubiquitously in specific areas such as corners or walls of a room, so they suck in and purify air through forced circulation by a blower fan, regardless of natural convection phenomenon, thereby providing high-performance blowing. Even if a fan is installed, there are limits to circulating and purifying the entire air in the room. Therefore, the air purification efficiency is only limited to the vicinity of the air purifier, and has the disadvantage of being insufficient to purify the air of the entire room.

In recent years, in order to solve the above problems, air purification means have been built into lighting fixtures installed on the ceiling of indoor spaces, so that indoor air can be purified efficiently through convection phenomenon and at the same time, indoor space can be utilized efficiently. Research efforts are continuing.

As described above, as a prior art related to a lighting fixture with a built-in air purifying means, a lighting fixture with an air purifying device published in Patent Publication No. 10-2012-0000178 (published on January 4, 2012) is installed inside the lighting case. In a lighting fixture equipped with a lighting lamp and an air purifying device, the air purifying device includes an intake unit, a filter unit, a housing, a discharge unit, and a plurality of units disposed at predetermined intervals inside the housing and radiating ultraviolet rays into the housing. It includes an ultraviolet light-emitting diode, and the housing is disposed along the inner side of the lighting case so that inlet air can flow along the side circumference of the lighting case.

In another prior art, Public Utility Model No. 20-2011-0006095 (publication date: June 17, 2011), a lighting lamp equipped with an air purifying means is an indoor lighting lamp consisting of a case, a base, and a light bulb, including the above. By equipping the lighting with an air purifying means and configuring it to share some components of the power supply unit that supplies power to the light bulb and the air purifying means, the production price of the product can be reduced, the size minimized, and the product is clear and clean to the user. It is characterized by providing fresh air to contribute to disease prevention and health promotion.

However, in the case of a lighting lamp having an air purifying means configured as described above, indoor air is forcibly sucked into the lighting fixture through a filter formed inside the lighting fixture and a blowing fan, and the sucked air is purified by passing through the filter. There is a problem in that it is impossible to sterilize bacteria or pathogens, such as viruses such as COVID-19, contained in indoor air because it is configured to be discharged to the outside of the lighting fixture.

In addition, conventional air purification means are operated only when lighting fixtures are turned on, which reduces efficiency and makes it impossible to stably maintain comfortable indoor air quality.

In addition, there is a problem in that the purification ability is significantly reduced in the case of narrow-shaped lighting fixtures because the indoor air that flows into the air purification means passes through the filter and is then discharged to the outside.

In addition, the housing is characterized in that it has a hollow interior and has a shape selected from the group consisting of a rectangular shape, an oval shape, a polygonal shape, and a circular shape.

In addition, the pre-filter is installed in a replaceable form to filter and collect fine dust and is made of non-woven fabric or microfiber mesh.

The ultraviolet lamp unit has a sterilizing and killing effect on bacteria, mold and microorganisms, and includes an ultraviolet lamp that emits ultraviolet C with an ultraviolet wavelength in the range of 250 nm to 260 nm, and an infrared heater that regulates the humidity of indoor air. Do it as

As described above, in the lighting fixture that purifies and sterilizes indoor air according to the present invention, the air purifying means is located at the optimal location where the flow of indoor air due to natural convection phenomenon is concentrated, that is, in the central part of the ceiling where the indoor lighting fixture is installed. As the forced flow direction of air by the air purification means matches the flow of indoor air by natural convection, it accelerates the flow of indoor air and ultimately activates the circulation of the entire indoor air, thereby purifying the air throughout the entire room evenly. This has the effect of significantly improving air purification efficiency, and has the effect of enabling wide use of indoor space while implementing air purification functions since there are no spatial restrictions on installation.

Moreover, the contaminated air flowing into the air purification means is formed on one side of the inlet hole, so that relatively bulky dust is first removed, secondarily passes through a HEPA filter, and harmful substances are secondarily removed, and a plurality of ultraviolet rays are transmitted. By sterilizing lamps, bacteria and viruses such as coronavirus are sterilized and purified indoor air is discharged, which has the effect of stably maintaining a clean and comfortable indoor environment at all times.

In addition, the filter is formed as a double layer of a pre-filter and a HEPA filter, so that it can be used efficiently by extending the life of the filter, and at the same time, each filter can be replaced through the simple process of separating the finish plate, allowing the user to use it independently. There are constitutive effects that can be managed.

In addition, the contaminated air introduced into the air purifying means is circulated inside the housing by the configuration of the guide plate formed inside the lighting housing, and is guided to contact the ultraviolet sterilizing lamp as much as possible, thereby eliminating bacteria and bacteria using the UV light source. It has the effect of maximizing the sterilizing power of viruses.

In addition, the lighting fixture having the function of purifying and sterilizing indoor air can independently control the use of indoor lighting and air purifying means, so that lighting and air purifying means can be used at the same time or by selecting lighting and air purifying means. It can be used in a variety of ways depending on the user's usage pattern, and has the effect of controlling the operation easily and comfortably using a controller that is connected to the lighting fixture by wire or wirelessly.

This is a perspective view showing the appearance of another embodiment of a lighting fixture.

The present invention relates to a lighting fixture that has the function of purifying and sterilizing indoor air. To be more specific, the lighting function of the lighting fixture installed on the indoor ceiling is maintained while the indoor air introduced by the suction fan mounted inside the lighting fixture is As it passes through the pre-filter, pollutants such as dust contained in the indoor air are removed, and as it passes through multiple sterilizing lamps, the air is not only purified but also sterilized for bacteria and pathogens contained in the indoor air, allowing clean and fresh air into the indoor space. It can provide a comfortable living environment for residents by providing a comfortable living environment for residents, and by sterilizing germs, dust, mold, and bacteria that pollute the air and preventing their cultivation, it can greatly contribute to preventing disease and improving the health of residents. This relates to a new type of lighting fixture that has indoor air purification and sterilization functions.

The lighting fixture (A) having indoor air purification and sterilization functions according to the present invention largely includes a housing 100 in which an air purifying means 30 and a substrate frame 10 on which a plurality of LED modules 20 are installed are accommodated; , It consists of a cover 200 formed on the lower part of the housing 100 and a finishing plate 300 that seals the upper part of the housing 100 and is connected to the ceiling.

The housing 100 is composed of a strip shape with an approximately "ㄷ" shaped cross section with the upper and lower portions penetrating, and has a plurality of air inlet holes 11 on one side and a plurality of air inlet holes 11 on the other side corresponding to the air inlet holes 11. Two air discharge holes 12 are formed.

In addition, inside the housing 100, a substrate frame 10 in which an LED module 20 is formed on the lower surface and an air purifying means 30 is installed on the upper surface is coupled.

Meanwhile, the shape of the housing 100 is shown in the drawing as a rectangular shape, but is not limited to this, and can be provided in various shapes such as oval, polygon, and circular as shown in FIGS. 7 and 8, allowing the user to It is possible to select a housing 100 of a shape that matches the image of the indoor space.

In addition, it is explained that the LED module 20 and the air purifying means 30 are integrally formed at the upper and lower parts of the substrate frame 10, but this is not limited to this and is formed by a separate plate (not shown). Each configuration can be installed independently.

The LED module 20 has a plurality of LDE lamps 21 fixedly installed on the bottom of the substrate frame 10, connected to a ballast (not shown) on one side, and turned on and off depending on whether power is supplied.

The LED module 20 as described above is composed of a typical configuration used as a general indoor light, and a detailed description of its configuration will be omitted.

The air purifying means 30 is formed on the upper surface of the substrate frame 10 and is coupled to the inside of the air inlet hole 11 of the housing 100 in a replaceable form, and removes contaminated air sucked through the air inlet hole 11. A pre-filter (31) that primarily separates dust from the pre-filter (31) is combined in a replaceable form at a certain distance from the pre-filter (31), and polluted air from which dust is primarily removed passes through the pre-filter (31). A HEPA filter (32) is a mixture of a natural palm tree filter that secondarily removes fine dust, odors, and bacteria, and is installed at a certain distance on one side of the HEPA filter (32) to mix with the contaminated air. An ultraviolet lamp is formed by forming a plurality of ultraviolet lamp units 33 that kill the coronavirus and an inclined surface 341 that is fixed to the substrate frame 10 and has an air moving hole 342 on the side where the ultraviolet lamp unit 33 is formed. Contaminated air is circulated around the unit 33 in a manner that rotates from the bottom to the top by the inclined surface 241, so that the contaminated air is induced to be in contact with the ultraviolet lamp unit 33 for a long time, and the other side is in close contact with the housing 100. It includes a discharge box 34 and an exhaust fan 35 formed inside the discharge box 34 to suck in clean air through the air moving hole 342 and discharge it to the outside through the air discharge hole 12. It is composed.

The pre-filter 31 is installed in a replaceable form in the pre-filter module housing 13 formed on the upper surface of the substrate frame 10 where the air inlet hole 11 is formed, filters and collects fine dust, and uses a type of non-woven fabric or microfiber net. It is manufactured so that it can filter relatively large dust particles.

The HEPA filter 32 is formed at a position spaced apart from the pre-filter 31 at a predetermined distance and is installed in a replaceable form in the HEPA filter module housing 14 formed on the upper surface of the substrate frame 10, and contains a strong adsorption force in the air. It has a purifying power that cleanly removes up to 99.97% of harmful substances such as house dust, mites, viruses, mold, etc. that are harmful to the human body, as well as fine pollutants of approximately 0.3 microns in size, which are the most harmful particles to the human body, keeping the polluted air clean. It plays a purifying role.

The ultraviolet lamp unit 33 is configured to emit ultraviolet rays (UltraViolet rays) and has the effect of sterilizing and killing microorganisms such as bacteria, mold and viruses such as coronavirus contained in the air, and includes an ultraviolet lamp 331, It may be composed of an infrared heater 332 that can control the humidity of the internal air.

The ultraviolet lamp 331 may be a fluorescent lamp-type ultraviolet fluorescent sterilizing lamp or an ultraviolet LED sterilizing lamp using an LED with a specific wavelength with high sterilizing power. In particular, the ultraviolet LED sterilizing lamp is cheaper than the ultraviolet fluorescent sterilizing lamp. Although it is expensive, it is preferable to use an ultraviolet LED sterilizing lamp, which can be used for a long time and can overcome the inconvenience of having to replace the lamp, and can overcome the problem of the sterilizing lamp breaking down due to external shock.

The ultraviolet rays (UltraViolet rays) emitted by the ultraviolet lamp 331 are part of electromagnetic waves and refer to electromagnetic waves with a wavelength of 100 to 380 nm (1 nm = 10-9 m), and are divided into ultraviolet rays A, ultraviolet B, and ultraviolet C depending on the wavelength. It can be shared. In particular, ultraviolet C can be divided into extreme ultraviolet rays, ozone-generating rays, and sterilizing rays. The wavelength of ultraviolet light that has a sterilizing effect on microorganisms such as bacteria, mold, and yeast is 250 nm to 260 nm, and among them, the 253 nm wavelength has the greatest sterilizing effect. Sunlight contains a lot of ultraviolet rays, and it is known that these ultraviolet rays have the effect of killing bacteria and mold.

The infrared heater 332 adjusts the humidity by removing moisture contained in the air that is sucked in through the air inlet hole 11 and discharged through the air discharge hole 12 by the operation of the exhaust fan 35. It helps control the high humidity of indoor space during summer.

Additionally, the ultraviolet lamp 331 and the infrared heater 332 may operate simultaneously or may be operated selectively by the user.

On the other hand, the sterilization of air by the ultraviolet lamp 331 is formed on one side of an inclined surface that circulates the air so that the internal air can contact the ultraviolet lamp 331 as much as possible without being easily discharged through the air discharge hole 12 ( It can be maximized by the configuration of the discharge box 34 with 341)

That is, the inclined surface 341 is configured in a round shape with an air moving hole 342 formed at the bottom, so that the air flowing in from the HEPA filter 32 is rotated at the top of the substrate frame 10 of the housing 100. By moving, the air is actually induced to float around the ultraviolet lamp unit 33, thereby delaying contact with the ultraviolet lamp unit 33 to the maximum, thereby maximizing the sterilizing power of bacteria and viruses using the UV light source.

In addition, the floating purified air is sucked into the discharge box 34 through the air movement hole 342 by the operation of the discharge fan 35 formed inside the discharge box 34 and is discharged through the air discharge hole 12. It is discharged to the outside through

The cover 200 is coupled to the lower part of the housing 100 to cover the LED module 20 formed in the lower part of the substrate frame 10, so that the light from the LED module 20 can be diffused to the outside throughout the cover 200. It is structured so that

The finishing plate 300 is coupled to the upper part of the housing 100 to seal the air purifying means 30 formed on the upper surface of the substrate frame 10, and is coupled to the housing 100 in a detachable form using bolts. A plurality of assembly holes 310 are formed on the surface for installing the lighting device A having the indoor air purification and sterilization function to the ceiling.

Meanwhile, the operation of the lighting fixture (A) configured as above and having the function of purifying and sterilizing indoor air according to the present invention is controlled by a controller 400 attached to the wall or provided in the form of a typical remote control.

The controller 400 is for driving the air purifying switch 410 and the LED module 20 for driving the air purifying means 30 installed inside the housing 100, as shown in FIGS. 5 and 6. An electric switch 420, an overall switch 430 that simultaneously turns on and off the air purifying means 30 and the LED module 20, and an automatic operation of the air purifying means 30 and the LED module 20. Alternatively, it consists of an automatic/manual selection switch 440 that can be selected manually.

That is, when it is desired to use only the lighting means of the lighting fixture, the controller 400 operates to turn on the LED lamp 21 of the LED module 20 through the control unit 450 by pressing the electric switch 420, and performs an air purifying function. If you want to use , press the air purifying switch 410 to operate the air purifying means 30 through the control unit 450 to purify the polluted indoor air.

In addition, if you want to use the lighting and air purifying functions at the same time, press the overall switch 430 to simultaneously operate the LED module 20 and the air purifying means 30 through the control unit 450 to light up the indoor space. In this condition, indoor air purification can be carried out at the same time, providing comfortable indoor air.

In addition, the lighting and air purification functions can be adjusted by selecting an automatic mode that operates for a set time by the automatic/manual selection switch 440 or a manual mode that can immediately control the operation, thereby improving indoor air quality and indoor air quality. The user can select and use it depending on the level of darkness in the space.

As described above, in the lighting fixture that purifies and sterilizes indoor air according to the present invention, the air purifying means is located at the optimal location where the flow of indoor air due to natural convection phenomenon is concentrated, that is, in the central part of the ceiling where the indoor lighting fixture is installed. As the forced flow direction of air by the air purification means matches the flow of indoor air by natural convection, it accelerates the flow of indoor air and ultimately activates the circulation of the entire indoor air, thereby purifying the air throughout the entire room evenly. This has the characteristic of significantly improving air purification efficiency. Moreover, the contaminated air flowing into the air purification means is formed on one side of the inlet hole, so relatively bulky dust is first removed, and secondarily a HEPA filter is used. Harmful substances are removed secondarily as they pass through, and viruses such as bacteria and corona are sterilized by multiple ultraviolet sterilizing lamps, and purified indoor air is discharged, thereby stably maintaining a clean and comfortable indoor environment at all times. There is.

In addition, the filter is formed as a double layer of a pre-filter and a HEPA filter, so that it can be used efficiently by extending the life of the filter, and at the same time, each filter can be replaced through the simple process of separating the finish plate, allowing the user to use it independently. There are features that can be managed.

In addition, the contaminated air introduced into the air purifying means is circulated inside the housing by the configuration of the guide plate formed inside the lighting housing, and is guided to contact the ultraviolet sterilizing lamp as much as possible, thereby eliminating bacteria and bacteria using the UV light source. It has features that can maximize the sterilizing power of viruses.
