Description

Sterilizing, mold inhibiting and deodorizing module and space sterilizer

TECHNICAL FIELD The present invention relates to an LED module and a space sterilizer having the same, which can remove bacteria, inhibit fungi, and remove odors caused by bacteria and fungi.

Generally, a urinal installed in a public toilet, which is a public facility such as a toilet seat or a highway resting place installed in a home, is susceptible to bloody urine, a mold and a germ Environment, which in such an environment causes an unpleasant smell of sticking the nose.

Particularly, the bacteria around the toilet urinals generate ammonia by alkalizing the elements of the urine, and then the urea is combined with the calcium ions (Ca2 +) in the urine, and is fixed in the urine and the floor around the urinal, Is a hotbed of bacterial growth. Since the alkalization of urea is accelerated by the increased bacteria, the increase of ammonia and the increase of urine are accompanied simultaneously, and the intensity of the odor continuously increases. In addition, humid environments with high humidity are the fundamental cause of the easy living of fungi. Fungi can cause runny nose, eye irritation, skin rash, especially asthma, and infants and children and respiratory diseases and allergies It is necessary to control the moisture and humidity conditions continuously to prevent the generation and propagation of fungi.

Generally, in order to clean the periphery of the urinal of a toilet, a disinfectant which is chemically sterilized is used. In the case of a chemical product, chlorine gas is generated along with oxidation (sterilization) action upon contact with organic matter , Respiratory mucous membranes, etc., and there is a risk that the operator suffers suffocation when used in a place where all sides are blocked, so that careful handling and use thereof are required.

In addition, the frequent use of many people has the problem that it is difficult to maintain a constant cleanliness of the urinal and toilet seat such as toilet seat, which is a cause of contamination of odor and germ propagation.

Although a method of using ultraviolet rays and a photocatalyst to sterilize such a space has been studied in advance, ultraviolet rays are not suitable for sterilizing a wide space.

In general, ultraviolet light used for sterilization is 250 nm, which is the strongest sterilizing power among UV-C, and 99% sterilization of Escherichia coli, diphtheria, and foreign bacteria by irradiating ultraviolet light having a strength of 100 uW per 1 cm 2 for 1 minute However, since ultraviolet light uses mercury, there is a risk of environmental problems and mercury exposure due to breakage in use. In addition, most ultraviolet rays have adverse effects on eyes and skin when exposed to human body, The short wavelength of 250 nm region destroys DNA and induces skin cancer. If the intensity of irradiation to the retina or the skin is strong even at a long wavelength of 300 to 390 nm, it is harmful to the human body because it stimulates the eyes and skin.

Accordingly, even if the on / off control is performed through the proximity sensor recognizing the human approach, the detection range of the proximity sensor is limited when used in a wide space, so that the ultraviolet light is sufficiently exposed to the human being, Because it prohibits exposure, it is difficult to use in an open space. Ultraviolet light is accompanied by the generation of ozone, which is very harmful to humans.

On the other hand, when a photocatalyst is used, it is a method of decomposing and deodorizing organic substances by generating radicals having a very high reactivity. However, since the duration of the radicals is very short in proportion to the high reactivity of the radicals, In particular, it is difficult to apply the method because the sterilizing ability of floor space such as the urine of the main pollutant source and its surrounding floor is low.

In addition, even in the case of a shoe box to store shoe, it is discomfort to the user due to the smell and odor which are generated from the shoe to be stored from the shoe box to the outside. Such odor is caused by the sweat As a result of propagation by the germs breeding in the environment, the smell was caused in the shoebox.

In order to clean shoes stored in such shoeboxes, they are cleaned, deodorized, or managed using newspaper, but it is difficult to apply to shoe using leather material in case of washing, and a method of using deodorant or newspaper Can not have the effect of continuous deodorization because it is difficult to completely and continuously remove the bacteria, which is the source of the odor.

In addition, when ultraviolet rays are used for disinfection of shoe, discoloration and cracks are likely to occur in shoe fabrics, and the use thereof is not appropriate.

In addition, in the entire specification, when a part is referred to as being 'connected' to another part, it may be referred to as 'indirectly connected' not only with 'directly connected' . Also, to include an element does not exclude other elements unless specifically stated otherwise, but may also include other elements.

As shown in FIGS. 1A to 3, the space sterilizer 100 according to a preferred embodiment of the present invention is installed on a wall or a ceiling of a toilet or a shoe box in which a toilet, such as a urinal, (T), which is caused by toilet and footwear, is mixed light containing purple light and infrared light so as to suppress the propagation of germs and fungi caused by shoe, And at least one LED module (1).

The LED module 1 includes a module case 10 and a light source unit 20. The module case 10 has a transparent lid 11 covering an opened lower portion to have an internal space for accommodating the light source unit It is a structure.

Although the transparent lid 11 covering the open outlet of the module case 10 is shown and described as being fixed by a separate lid holder 12 assembled to the end of the case of the modular case 10, The position can be fixed.

The transparent cover 11 is fixed to the exit of the module case 10 and is not limited thereto. The transparent cover 11 may be fixed to the module case 10 at a distance And the focal distance to a source of contamination where bacterial and fungal bacteria are generated can be varied.

The transparent cover 11 may be provided as a diffusion lens for diffusing light generated from the light source 20 into a pollution source, or may be provided as a condenser lens for intensive irradiation with a pollution source.

That is, when the transparent lid 11 is made of a diffusing lens, the emission angle of the mixture light in which the violet light and the ultraviolet light generated by the violet LED 21 and the ultraviolet light 22 are diffused, It is possible to increase the sterilization range by broad irradiation.

When the transparent lid 11 is formed of a condensing lens, the emission angle of the mixed light mixed with the purple light and the ultraviolet light generated by the violet LED 21 and the ultraviolet LED 22 is narrowed and condensed It is possible to intensively sterilize the source of pollution by the mixed light, thereby increasing the sterilizing ability.

In addition, the module case 10 may further include a power supply unit such as a switched mode power supply (SMPS) for converting an external power source from AC to DC on the basis of the light emission driving characteristics of LEDs as a light source in addition to the light source unit.

The light source unit 20 includes at least one purple LED 21 for generating a purple light when powered on and at least one infrared LED 22 for generating infrared light when a power is applied, As shown in Fig.

Accordingly, the purple light emitted from the violet LED 21 and the infrared light generated from the infrared LED 22 are mixed at a predetermined ratio, and the mixed light is mixed through the transparent cover of the module case 10, Or a toilet such as a urinal or a source of pollution inside a sewing machine.

4A, 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, or as shown in FIG. 4B, A first module substrate 24a on which a plurality of the purple LEDs 21 are mounted and a second module substrate 24b on which a plurality of the infrared LEDs 22 are mounted.

In this case, the violet 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 upon power application, 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 fungus or bacteria generated in the pollution source T, the light of a specific wavelength band emitted from the violet LED 21 and the infrared LED 22 is converted into porphyrin And the excited porphyrin can convert stable oxygen existing in the cell into reactive oxygen species (ROS).

At this time, a proper amount of active oxygen helps the homeostasis of cells, but when the amount thereof is increased rapidly, it causes lipid peroxidation, protein denaturation, DNA damage and the like in the cells to kill bacteria.

In addition, the light of a specific wavelength band emitted from the infrared LED effectively penetrates bacteria having a lipid-structured cell wall, thereby contributing to the destruction of bacteria. Especially, infiltration of mycelial fungus is effective .

In addition, it is more effective in sterilizing action and is effective in inhibiting the generation of fungus by drying moisture which is essential for reproduction and growth of bacteria or fungus in a pollution source inside a toilet or a shoe box.

Since the principle and action of the sterilization of the purple light and the infrared light are different from the direct sterilization of the ultraviolet lamp harmful to the human body, sterilization can be applied in an open space such as a toilet, And continuously sterilizing and suppressing bacteria and fungus bacteria, it is possible to continuously maintain a clean state by eliminating the source of odor caused by bacteria and fungal bacteria.

The LED module 1 includes a control unit for controlling the power supplied to the plurality of purple LEDs 21 and the plurality of infrared LEDs 22 mounted on the light source unit so that the purple LED 21 And the infrared light generated from the infrared LED 22 may be appropriately adjusted and controlled according to various conditions of the pollution source.

The control unit may include a timer for generating a control signal for limiting the time for supplying external power to the light source unit. The timer may be a mechanical or an electronic timer, and may be exposed to an external surface of the module case desirable.

By the timer, the power supply is automatically shut off at the set time, thereby unnecessary power consumption can be prevented .

Meanwhile, the space sterilizer 100 having the LED module 1 having the above-described configuration includes a connection part 110 connected to the LED module 1 and a cradle 130 or 130a fixedly installed on a ceiling surface or a wall surface .

That is, the connection unit 110 includes a connection member 113 integrally assembled to the module case 10, and a rotation hole 113a formed in one side of the connection member 113, 112 having a predetermined length at one end thereof.

The coupling member 113 has a holder plate for fixing the body of the rotation body 112 to which a part of the body is rotatably assembled in the rotation groove 113a. However, And the rotary shaft can be elastically press-fitted so as to be difficult to be separated from the rotary groove.

The connection member 113 is formed with at least a fixed portion 112a through which the connection member 113 is inserted so as to generate a fixing force, And may include a screw 115.

Accordingly, the module case 10 having the light source unit can be irradiated with the irradiation angle of the mixed light to be irradiated as a pollution source in the light source unit 20 by the rotation tool 112 assembled so as to be rotatable 360 degrees in the rotation groove of the coupling body, It is simple and freely variable, and the variable irradiation angle can be maintained by the fixing screw.

As shown in FIGS. 1A and 1B, the mounting bases 130 and 130a are formed by recessing the assembly groove 133, which is assembled with the other end of the link 111 connected to the LED module 1, It is a fixed structure that is fixedly installed on a ceiling surface or a wall surface forming a space of a generation source.

The carriage 130 and 130a include a carriage 120 having a plurality of wheels 122 that are moved along a guide surface 122 formed in the mounting groove so as to vary the position of the LED module horizontally And the other end of the linkage connected to the LED module 1 may be connected to the carriage 120. [

Although the bogie 120 is shown as being composed of a moving means having a wheel that rolls along the guide surface, the bogie 120 is not limited to this, but includes moving means having a slider slidably moved along the guide rail, A motor member or a cylinder member may be separately provided so as to control the positional movement of the LED module using the carriage as a driving force.

Accordingly, the LED module 1 is moved horizontally along the guide rails 122 formed in the mounting grooves 133 of the mounts 130 and 130a, and irradiated with the purple light and ultraviolet light, The position can be varied.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
