Description

LED module for sterilization, mold control and odor removal, and space sterilizer having the same

The present invention relates to an LED module capable of removing bacteria, inhibiting mold, and removing odors caused by bacteria and mold bacteria, and a space sterilizer having the same.

In general, urinals installed in public toilets, which are public facilities such as toilet seats or highway rest areas, are susceptible to active propagation of fungi and bacteria due to splashing of urine or bacteria or water on shoes. It is the environment, and in such an environment, it causes an unpleasant smell that pricks the nose.

In particular, the bacteria around the urinal in the bathroom produce ammonia by alkalizing the urea of the urine, and after that, the urea binds to calcium ions (Ca2+) in the urine, and then becomes urinary by being fixed inside the urinal and the floor around the urinal. Silver becomes a hotbed for bacterial proliferation, and the alkalinization of urea is accelerated due to the increased bacteria. Therefore, the increase in the occurrence of ammonia and the increase in urolithiasis are accompanied at the same time, and the intensity of the odor continues to increase. In addition, a humid environment with high humidity is a fundamental cause for fungal bacteria to easily inhabit, and fungi can worsen runny nose, eye irritation, skin rash, especially asthma. Since it can further affect those with weakened immunity and those with weakened immunity, it is necessary to continuously manage moisture and humidity conditions to inhibit the production and reproduction of fungi.

In general, to keep the urinals in the bathroom clean, chemically disinfecting disinfectants are used, but in the case of chemical products, chlorine gas is generated along with oxidation (sterilization) when it comes into contact with organic matter (contaminants). , It irritates the respiratory mucosa, etc., and there is a risk of suffocating the worker when using it in a place where all sides are blocked, so care must be taken in handling and using it.

In addition, due to frequent use by many people, it is difficult to maintain continuous cleanliness for toilets such as urinals and toilets, which are the cause of contamination of odors and bacterial growth.

In order to sterilize such spaces, a method using ultraviolet rays and a photocatalyst has also been studied in advance, but ultraviolet rays are not suitable for sterilizing large spaces.

In general, ultraviolet light used for sterilization uses the 250nm area, which has the strongest sterilization among UV-C, and 99% of E. coli, diphtheria, and shigella bacteria are sterilized by irradiating ultraviolet light with an intensity of 100uW per 1 cm However, since ultraviolet light uses mercury, there is always a risk of environmental problems and exposure to mercury due to breakage during use, and most of the ultraviolet light adversely affects the eyes and skin when exposed to the human body. Short wavelengths in the 250 nm range destroy DNA and cause skin cancer, and even with long wavelengths of 300 to 390 nm, if the intensity of irradiation to the retina or skin is strong, it irritates the eyes and skin, so there is a problem that it is harmful to the human body.

Accordingly, even if on/off control is performed through a proximity sensor that recognizes a person's approach, the detection range of the proximity sensor is limited when used in a large space, so there is sufficient room for ultraviolet light to be exposed to people. Because exposure is prohibited, it is difficult to use it in an open space. In addition, ultraviolet light accompanies the generation of ozone, and the generated ozone is very harmful to humans.

On the other hand, in the case of using a photocatalyst, this is a method of decomposing and deodorizing organic substances by generating radicals with very high reactivity, but the duration is very short in proportion to the high reactivity of the radicals, so it does not have a remarkable effect on air deodorization. In particular, it was difficult to apply because the sterilization ability for floor spaces such as urinals or the surrounding floors, which are the main pollutants, was poor.

In addition, even in the case of the shoe rack where the shoes are stored, the smell and odor that is generated from the shoe rack and leaked out from the shoe rack causes discomfort to the user.These odors cause sweat from the feet and poor ventilation when worn. As the propagation was carried out by the bacteria that reproduced in the environment, it became the cause of the odor in the shoe cabinet.

In order to cleanly manage the shoes stored in these shoe cabinets, they are washed, deodorant, or newspaper, etc., but it is difficult to apply to shoes using leather, and a method of using deodorant or newspaper, etc. Since it is difficult to completely and continuously remove the bacteria that are the source of silver odor, it cannot have the effect of continuous odor removal.

In addition, when ultraviolet rays are used for sterilization of shoes, discoloration and cracks are easily generated in the preparation of shoes, and thus there is a problem that the use thereof is not appropriate.

However, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

In addition, the same reference numerals are used for portions having similar functions and functions throughout the drawings.

In addition, throughout the specification, when a part is said to be'connected' with another part, it is not only'directly connected', but also'indirectly connected' with another element in the middle. Includes. In addition, "including" a certain component means that other components may be further included, rather than excluding other components unless specifically stated to the contrary.

The space sterilizer 100 according to a preferred embodiment of the present invention is installed on the wall or ceiling surface of a toilet in which toilets such as a left toilet or urinal are installed, or a shoe rack where shoes are stored, as shown in FIGS. 1A to 3. In order to suppress the propagation of bacteria or fungi caused by the shoes or shoes, and to sterilize the source of contamination and its surroundings, the mixed light including purple and infrared light is irradiated with the contamination source (T) caused by the toilet and shoes. It includes at least one LED module (1).

The LED module 1 includes a module case 10 and a light source unit 20, and the module case 10 has an internal space for accommodating the light source unit by having a transparent cover 11 covering the open lower part. It is a structure.

The transparent cover 11 covering the open outlet of the module case 10 has been illustrated and described as being fixed in position by a separate cover holder 12 assembled at the end of the module case, but is not limited thereto and is independently Position can be fixed.

In addition, the transparent cover 11 has been illustrated and described as being fixed at the outlet of the module case 10, but is not limited thereto, and is farther away from the light source unit 20 fixedly installed in the module case 10 in the optical axis direction. It can be assembled to be movable so as to change the focal length to the source of contamination where bacteria and fungi are generated while being lost or in close proximity.

The transparent cover 11 may be provided as a diffusion lens to diffuse the light generated from the light source unit 20 to the contamination source, or may be provided as a condensing lens to intensively irradiate the contamination source.

That is, when the transparent cover 11 is made of a diffusing lens, the radiation angle of the mixed light of the violet light and ultraviolet light generated from the violet LED 21 and the ultraviolet LED 22, respectively, is diffused to prevent the contamination source. The sterilization range can be increased by wide irradiation.

In addition, when the transparent cover 11 is made of a condensing lens, the emission angle of the mixed light of the violet light and ultraviolet light generated from the violet LED 21 and the ultraviolet LED 22 is narrower and condensed. By intensive sterilization of the contaminant source by the mixed light, sterilization capacity can be increased.

In addition, in addition to the light source unit, a power supply unit such as a switched mode power supply (SMPS) for converting external power from AC to DC due to the light emission driving characteristics of the LED as a light source may be separately included inside the module case 10.

The light source unit 20 includes at least one purple LED 21 that generates purple light when power is applied, and includes at least one infrared LED 22 that generates infrared light when power is applied to the module case 10 ) Can be mounted in the internal space.

Accordingly, the purple light generated from the purple LED 21 and the infrared light generated from the infrared LED 22 are mixed at a certain ratio, and the mixed light is mixed with the left toilet through the transparent cover of the module case 10. Or it can be concentrated irradiation as a contaminant source inside a toilet or a room such as a urinal.

Here, the light source unit 20 includes at least one module substrate 23 on which a plurality of the purple LEDs 21 and the infrared LEDs 22 are mounted, as shown in FIG. 4A or as shown in FIG. 4B. , A first module substrate 24a on which a plurality of purple LEDs 21 are mounted, and a second module substrate 24b on which a plurality of infrared LEDs 22 are mounted.

At this time, the purple LED 21 mounted on the module substrate 23 or the first module substrate 24a generates light having a wavelength band of 360 to 420 nm when power is applied, and the module substrate 23 or the second The infrared LED mounted on the module substrate 24b generates light having a wavelength band of 700 to 1500 nm.

That is, in order to sterilize fungi or bacteria generated from the contamination source (T), the light of a specific wavelength band emitted from the purple LED 21 and the infrared LED 22 is porphyrin, a photosensitizer present inside the cells of the bacteria. It is absorbed into the back and excited (excited), and the excited porphyrin or the like can change the stable oxygen present in the cell into reactive oxygen species (ROS).

At this time, an appropriate amount of free radicals helps the homeostasis of the cell, but if the amount is rapidly increased, it causes lipid peroxidation, protein denaturation, DNA damage, etc. in the cell, thereby killing the bacteria.

In addition, the light of a specific wavelength band emitted from the infrared LED effectively penetrates the bacteria having the outer cell wall of a rigid lipid structure, helping to kill the bacteria, and in particular, it is effective to penetrate the fungal bacteria composed of hyphae. .

In addition, it is more effective for sterilization by drying moisture essential for reproduction and growth of bacteria or fungi from the pollutant source inside the toilet or shoe cabinet, and is effective in inhibiting the production of fungi.

Since the principle and action of sterilization of purple and infrared light is different from the direct sterilization of ultraviolet lamps that are harmful to the human body, sterilization can be applied in open spaces such as toilets, and it is safer to the human body than using chemical products. And, by continuously sterilizing and inhibiting bacteria and fungi, it is possible to continuously maintain a clean state by removing the source of odors caused by bacteria and fungi.

In addition, the LED module 1 includes a control unit for controlling power supplied to each of the purple LEDs 21 and the infrared LEDs 22 mounted in a plurality of the light source unit, so that the purple LEDs 21 when power is applied by the control unit. ) And the infrared light generated from the infrared LED 22 are mixed and the light mixing ratio of the mixed light irradiated can be appropriately adjusted according to various conditions of the contamination source.

Such a control unit includes a timer for generating a control signal limiting the time for supplying external power to the light source unit, and the timer is made of a mechanical type or an electronic type and is exposed to the outer surface of the module case for easy user manipulation and use. desirable.

Accordingly, when the user sets the operation time to the timer, the purple LED 21 and the infrared LED 22 of the light source unit 120 operated by an external power supply are used to use the mixed light of the purple light and the infrared light, respectively. It is possible to perform a sterilization function to sterilize bacteria and gomphi bacteria remaining in the toilet or its surroundings, inside the shoe cabinet for a certain period of time, and by automatically shutting off the supply power at a set time by the timer, unnecessary power consumption can be prevented. .

On the other hand, the space sterilizer 100 having the LED module 1 having the above-described configuration includes a connection unit 110 connected to the LED module 1 and a holder 130 and 130a fixedly installed on a ceiling or wall surface. I can.

That is, the connection part 110 has a connection body 113 integrally assembled with the module case 10, and a rotation tool that is assembled corresponding to the rotation groove 113a recessed in one surface of the connection body 113 ( It includes a connecting rod 111 of a predetermined length having 112) at one end.

In addition, the connector 113 has been illustrated and described as having a holder plate for fixing the remaining body of the body of the rotating sphere 112 in which a part of the body is rotatably assembled to the rotating groove 113a. It is not, and the rotating sphere can be elastically press-fitted to the rotating groove so that it is difficult to escape from the outside.

In addition, the connector 113 is at least fixed through the connector 113 so as to generate a fixing force by contacting the end of the rotating sphere 112 with a portion of the body rotatably assembled to the rotating groove 113a. It may include a screw 115.

Accordingly, the module case 10 having the light source unit adjusts the irradiation angle of the mixed light irradiated from the light source unit 20 to the contamination source by the rotating hole 112 assembled to freely rotate 360 degrees in the rotation groove of the connector. It is simple and freely variable, and the variable irradiation angle can be maintained by the fixing screw.

In addition, as shown in Figs. 1A and 1B, the cradles 130 and 130a are contaminated by forming an assembly groove 133 that is assembled with the other end of the connecting rod 111 connected to the LED module 1 in the lower surface. It is a fixed structure that is fixedly installed on the ceiling or wall that forms the space of the generator.

And the cradle (130, 130a) includes a cart 120 having a plurality of wheels 122 that are moved along a guide surface 122 formed in the assembly groove so that the position of the LED module can be changed in a horizontal direction, , The other end of the connecting rod connected to the LED module 1 may be connected to the bogie 120.

Herein, the bogie 120 is illustrated and described as being made of a moving means having a wheel that is rolled along the guide surface, but is not limited thereto, and is made of a moving means having a slider that slides along a guide rail. A motor member or a cylinder member may be separately provided so as to control the position movement of the LED module as a driving force using the bogie.

Accordingly, the LED module 1 is moved horizontally along the guide rail 122 formed in the assembly grooves 133 of the cradles 130 and 130a and irradiated with violet light and ultraviolet light, which are mixed light irradiated to the pollution source. You can change the position.
