Description

Lamp package for prevention of epidemics and sterilization

The present invention relates to a lamp package for disinfection and disinfection. More specifically, the present invention relates to a lamp package that can rapidly prevent and sterilize air, objects, and household items using a 222 nanometer ultraviolet lamp.

The coronavirus, which originated in Wuhan, China, in early 2020, has spread worldwide in just three months with an advanced means of transportation, threatening the world, and the number of confirmed cases is increasing, exceeding 20 million in early August 2020. Vaccines may become useless due to the occurrence of multiple strains of the virus, and even if the coronavirus disappears, a pandemic in which other viruses attack humanity may continue.

If wild animals, livestock, or fish are eaten raw, viruses and bacteria from the animals eaten are transmitted to the human body, and like the coronavirus, it can spread around the world in just a few months.

Therefore, there is a need for a device capable of sterilizing and preventing highly contagious viruses and antibiotic-resistant bacteria. For example, we need a device that does not harm the human body, such as 254 nm during ultraviolet UVC. Since the sterilization effect by ultraviolet light is shown on virus-free methicillin-resistant bacteria (MRSA) and spores that are killed by alcohol, it is effective against almost all viruses or bacteria. The biggest cause of hospital infection (HSI) is metacillin-resistant bacteria (MRSA).

Ultraviolet UVC includes 254 and 222 nanometers. By the way, plants and animals must avoid 254nm ultraviolet ray when disinfecting, but in the case of 222nm, this is not the case. A so-called “excimer lamp” is a lamp that emits ultraviolet rays with a wavelength of 222 nm without using mercury. 222 nanometer UV light has the advantage of being safe for humans while its sterilization ability is several times stronger than that of general 254 nanometer UVC.

The sterilization ability of 222 nm ultraviolet light is high in the case of sterilization of MRSA/methacillin-resistant Staphylococcus aureus, which is a super-resistant bacteria, 15 to 10 mj/Cm ^{2 compared to UVC having a wavelength of 254 nm.} It shows an excellent sterilization effect in sterilization. In particular, the sterilization ability against the corona virus, which is a problem these days, is very good. It shows 99.9% sterilization ability with a light intensity of ^{6 mj/cm 2} or less against coronavirus, including influenza virus. The energy required for MRSA sterilization is 15 mj/cm ² , and all bacteria at a distance of 1 meter can be sterilized within 20 minutes.

Regarding a sterilization device or method using an excimer lamp, Patent Laid-Open No. 10-2020-0024951 discloses a method of sterilizing by irradiating ultraviolet rays, in order to suppress the effect on the human body and to suppress the odor generated after ultraviolet irradiation. Disclosed are a process of irradiating the skin of a finger or arm with ultraviolet rays of 200 nm or more and 230 nm or less, and a process of applying an external skin preparation, cosmetic, or aqueous solution containing amino acids or amino acid derivatives to the area irradiated with ultraviolet rays of the skin. . Patent Laid-Open No. 10-2018-0002921 discloses a method for sterilization by irradiating a 222 nm excimer lamp on the surface of sliced cheese. Patent No. 10-0580764 discloses a method for sterilizing a packaging sheet material, wherein hydrogen peroxide is applied to the packaging sheet material and irradiating the packaging sheet material with light comprising one or more UV wavelengths of about 200 nm to 320 nm, and have.

However, none of the above prior patents discloses the contents of giving or effectively disinfecting and sterilizing the air of daily life such as industrial activities.

The present invention has been devised in consideration of these circumstances, and provides a lamp package that can rapidly prevent and sterilize air and objects using a 222 nanometer ultraviolet lamp.

Therefore, the present invention is installed in spaces or homes such as elevators, emergency patient transfer vehicles (ambulances), operating rooms, doctor's conference rooms, cooking rooms and rest rooms, and continuously irradiates UVD rays that are not harmful to the human body to keep indoor air and equipment remaining. An object of the present invention is to provide a lamp package that can sterilize viruses and create a clean environment.

The present invention may be composed of a combination of at least any one of individual components and individual functions included in each embodiment.

<Configuration of lamp package (1) of the present invention>

1 is a structural diagram of a lamp package 1 of the present invention.

The exterior of the lamp package 1 is defined by a housing 2 of any shape, such as a square or a circle. In the lower part of the housing 2, a lower air guide plate 3 forming a “v”-shaped straight line is installed so as to occupy a significant portion of the lower part. The lower air guide plate 3 is suspended on the upper surface of the housing 2 by the lower plate support 4 . The lower plate support 4 may be, for example, a circular column.

On the left side of the housing 2, the lamp support 6 and the lamp 5 are installed sequentially from the inside, and the light diffusion plate 100, which is a feature of the present invention, is installed in front of the lamp 5. The lamp 5 is preferably an excimer lamp that emits ultraviolet light of 225 nm. The lamp 5 sterilizes the bacteria attached to the surface of the object to be irradiated by far-infrared rays, and at the same time sterilizes the bacteria contained in the air. The extended end of the light diffusion plate 100 is fixed to the upper surface and the side surface of the housing 2, for example, by bolting. As will be described later, a slot 106 surrounding the side surface of the light diffusion plate 100 is formed, the lower air passes through the lower slot 106 and the upper air passes through the upper slot 106 to pass through the lamp 5 ) and is sterilized.

A fan module 9 is installed at a lower portion of the lower air guide plate 3 opposite to the lower air guide plate 3 . The fan module 9 includes at least a fan and a fan motor for driving the fan. The fan module 9 is installed on the base 13 through the elastic pad 10 to minimize the effect of vibration. The base 13 is made of a material through which air passes or otherwise perforates a slot for the passage of air. A filter module 11 is coupled to a lower portion of the base 13 with a magnetic member 12 interposed therebetween. Accordingly, the filter module 11 is easily detachable from the base 13 when there is a need for replacement. The filter module 11 includes a filter, and it is preferable not to use a HEPA filter such as HEPA for the purpose of sterilization of the present invention and for smooth air circulation.

An inverter 7 is installed on the right wall of the housing 2 . The inverter 7 is connected to the lamp 5 through a cable 8 , converts household or commercial power (not shown) into direct current and supplies it to the lamp 5 .

An upper air guide plate 14 inclined downwardly outward is installed on the upper left side of the housing 2 . The upper air guide plate 14 is suspended on the upper surface of the housing 2 by the upper plate support 15 .

The operation of the present invention configured in this way will be described as follows.

First, when the fan module 9 is driven, air from which dust or foreign substances are removed passes through the filter module 11 and enters through the lower part of the housing 2 . Since the path of air is blocked by the lower air guide plate 13, a significant amount of air rises to the left and flows through the slot 106 in the direction of the arrow “A” and collects in the front of the ramp (5). Some of the remaining air is directed to the lamp 5 on the left and the inverter 7 on the right, so these members are naturally cooled by the air. Cooling of these members is essential, otherwise the temperature rises above 80 degrees, because the irradiating power of the lamp decreases as the temperature rises.

The remaining residual air and the cooled air are blocked by the lower plate support 4 and cannot enter the space of the housing 2 , and thus circulate while ascending and are guided by the upper air guide plate 14 . It flows in the direction of arrow “B” through the slot 106 above and gathers in the front of the ramp 5 .

In front of the ramp (5), the air flows from the upper and lower parts and collides with each other, and a vortex is formed, which increases the residence time in front of the ramp (5). Therefore, it is possible to reliably and effectively repeatedly disinfect the air by using the ultraviolet excimer lamp. In other words, by guiding the flow of air and irradiating far-ultraviolet rays from a short distance, immediate sterilization is possible, and this operation is repeated to remove various bacteria and viruses in the air.

2 is a front view of the light diffusion plate 100 of the present invention viewed from “C”.

The light diffusion plate 100 has a frame formed of four light diffusion surfaces 101 , 102 , 103 , 104 that form an enlarged shape toward the outside (the left side of FIG. 1 , the direction from the paper surface of FIG. 2 ). The diffusion angles of the light diffusion surfaces 101, 102, 103, and 104 are 20 to 25 degrees with respect to the lamp. The light diffusion surfaces 101 , 102 , 103 , and 104 are made of a metal material having a property of reflecting light. For example, stainless steel. The thickness is preferably around 0.5mm, and the amount of reflection is maximized by mirror-finishing.

For example, three slots 106 are formed in each of the light diffusion surfaces 101 , 102 , 103 , and 104 to be horizontally long. In addition, it is firmly fastened to the housing 2 by a plurality of fastening members 110 formed on the rim.

Referring again to FIGS. 1 and 2 , the air flowing in from the upper and lower portions of the housing enters the interior of the light diffusion plate 100 through the slots 106 formed on the slopes, forms a vortex, and flows outward, at this time the lamp The effect that all of the air is sterilized by light without omission or loss of ultraviolet rays because it receives the light irradiated in (5) directly and at the same time continues to receive the reflected light from the light diffusion surfaces 101, 102, 103, 104 can be maximized. In other words, the light diffusion plate 100 functions as an effective collection means in addition to its own reflection function to broadly diffuse the light to expand the sterilization area.

3 is a front view of the lamp 5 of the present invention viewed from “C”.

Four excimer lamp trains (L1, L2, L3, L4) arranged to form a line from side to side form the pump (5). A lamp support 62 is installed vertically in the middle of the lamp trains L1, L2, L3, and L4 to firmly fix the optical module, but this is not an essential configuration of the present invention. The lamp trains (L1, L2, L3, L4) are mounted on the rear reflector 64, and the reflector 64 of the present invention is not a vertical plate, but a curved surface such as a spherical surface surrounding the lamp train, thereby providing an effect like a convex mirror. and the surface is mirror-finished like a mirror. The light emitted from the lamp trains (L1, L2, L3, L4) forward can be guided as much as possible without leaking to the surroundings, and the amount of light energy and illuminance can be greatly improved. Without the reflector 64, 10 to 25% of the lamp light amount is absorbed or diffusely reflected by the base wall of the lamp module, and thus the efficacy of the light is lost. The material of the reflective plate 64 is SUS 304, and the thickness is 0.5 to 3 mm, and it is good to mirror the surface to 8K.

<Installation and use of the lamp package (1) of the present invention>

The lamp package 1 of the present invention may be installed in a fixed type or a mobile type in a home or building.

Ultraviolet light with a wavelength of 222nm, which has been proven to have no adverse effect on the human body, is a safe ultraviolet ray in a limited space to sterilize the surface to be irradiated by far ultraviolet rays, as well as continuously distribute and sterilize the air in cramped spaces, such as elevators. It is possible to achieve a sterilization rate of 99.999%, etc.

Eliminates the possibility of transmission caused by various germs, including aerosols, which contain droplets in cramped spaces and viruses staying in the air, and coronaviruses on the walls of elevators. Full disinfection can be done clean. Sterilization of the surface of an object can be carried out within a few seconds because relatively short-distance investigation is possible in a limited space.

The present invention is installed in a relatively small space such as an elevator, an emergency patient transfer vehicle (ambulance), an operating room, a doctor's interview room, a cooking room and a rest room, etc. to continuously irradiate ultraviolet UVD that is not harmful to the human body to remove the virus remaining in the indoor air and equipment. Sterilization can create a clean environment.

When installing the lamp package (1) of the present invention, it is preferable to add a timer circuit to stop the operation during holidays or non-working hours.

In addition, in a relatively small space such as an elevator or an operating room, if the irradiation distance between a person and the lamp package (1) is too small, the prevention and sterilization effect is ineffective or insignificant. It can be controlled to stop and start or continue operation if not detected.

<Rotational operation of the lamp package (1) of the present invention>

In the case of using the lamp package 1 of the present invention, it may be necessary to widen the irradiation range of the lamp while rotating the lamp package 1 up, down, left and right, rather than being fixed, depending on the place of quarantine and sterilization.

For example, in a large elevator, there may be one button each on the left and right for each floor, or one button for the handicapped or children on the left and right again.

In this case, if the lamp is fixed on the upper part of one corner, if the irradiation direction of the lamp is biased to one side, it may be difficult to expect a wide range of sterilization and prevention effects.

If there is a way to rotate the lamp up, down, left and right rather than having a fixed irradiation direction even when a person is on board, there are safety devices such as turning off the lamp when a person boards it by controlling it with a program. Consideration should be given to the ^{maximum possible exposure of 22mj/cm 2} of UV rays of 222 nanometers per day for 8 hours per day, which was established by the Safety Association (ACGIH) 20 years ago.

When the lamp is focused on one place, the cumulative dose of irradiation for a certain part in a relatively short time may exceed ^{22mj/cm 2 .}

There cannot be an upper limit on the amount of irradiation for object irradiation, but in the case of human irradiation, it may exceed ^{22mj/cm 2 at a fixed focal point.} Therefore, it is necessary to completely prevent the case ^{where the irradiation amount at the installation site exceeds 22mj/cm 2} in any case in the case of personal irradiation by irradiating the lamp while rotating it up, down, left and right.

Currently, this is the only regulation on the maximum exposure to UV rays of 222 nanometers, so it is desirable to comply with it for now.

The motor rotating up, down, left and right uses an Arduino servo motor, etc. as shown in FIG. 4 and adjusts the irradiation direction and time using an irradiation direction program suitable for a place where the lamp package 1 is installed.

The necessity of quarantine by a program that sets the irradiation angle and intensity according to the location while irradiating the previously produced 222 nanometer ultraviolet rays most effectively and appropriately in almost all places such as the operating room, patient waiting room, consultation room, etc. meet the

Then, as the lamp package rotates up and down, left and right, so-called homogeneous irradiation is possible, and with the homogeneous irradiation method, there is no omission of even a part of the quarantine and sterilization, and it is possible to make full efforts for the quarantine at the installation site. Since the motor is used, it is possible to intensively investigate a specific part, and in particular, it is possible to intensively investigate a surgical tool or surgical site such as an operating room. Of course, even in this case, a required level of irradiation light can be induced by using an illuminometer.

Although the embodiment of the present invention has been described above, it does not limit the present invention, and various modifications and variations are possible with respect to the present invention. It is obvious that the scope of the present invention extends to the same or equivalent scope as the claims described below.
