Description

LED module for sterilization, mold suppression and odor removal and space sterilizer

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

In general, urinals installed in public toilets, such as toilets and highway rest areas installed in home toilets, are easily prone to mold and germs due to splashing urine around them or bacteria or water on shoes. Environment, which causes an unpleasant odor that stings in the nose.

In particular, the bacteria around the toilet urinals alkalinize the elements of the urine to produce ammonia, and then the elements bind to calcium ions (Ca2 +) in the urine, which are fixed in the urinal and the bottom of the urinal, etc. Is a breeding ground for bacterial growth, and because of the increased bacteria, alkalinization of urea is accelerated, so that the increase of ammonia is accompanied by an increase in urine, and the intensity of odor is continuously increased. In addition, humidity and high humidity conditions are a fundamental cause of fungi, and fungi can worsen runny nose, eye irritation, skin rashes, especially asthma, and can cause infants, children, respiratory illnesses and allergies. Since it can affect people who have, weakened immunity, etc., it is necessary to manage the continuous humidity and humidity conditions for the production and suppression of fungi.

In general, chemical disinfectants are used to clean the urinals of toilets, but chemical products produce chlorine gas with oxidation (sterilization) upon contact with organic substances (contaminants). , Respiratory tract mucous membranes, etc., and when used in the blockages everywhere, there is a risk of choking the worker requires attention in its handling and use.

In addition, due to the frequent use of many people, there is a problem that it is difficult to maintain a constant clean state of the toilet such as urinals and toilets that are the source of contamination of odors and bacteria propagation.

In order to sterilize these spaces, methods using ultraviolet light and photocatalyst have also been studied in advance, but ultraviolet light is not suitable for sterilizing large spaces.

In general, the UV light used for sterilization uses the 250 nm region, which is the strongest among the UV-C. If UV light with an intensity of 100 uW per 1 cm 2 is applied for 1 minute, E. coli, diphtheria, and dysentery can be killed 99%. However, since ultraviolet light uses mercury, there is a risk of environmental problems and exposure to mercury due to cracking. In addition, most ultraviolet light adversely affects the eyes and skin when exposed to the human body. The short wavelength in the 250nm region destroys DNA and causes skin cancer, and even a long wavelength of 300 to 390nm has a problem that it is harmful to the human body because it irritates the eyes and skin when the intensity irradiated to the retina or skin is strong.

Accordingly, even if the on / off control is performed through a proximity sensor that recognizes a person's approach, when the sensor is used in a large space, the detection range of the proximity sensor is limited, so that UV light may be exposed to a person. It is difficult to use in open space because the exposure is prohibited. In addition, ultraviolet light is accompanied by 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 high reactivity, but the retardation is very short in proportion to the high reactivity of the radicals, and thus does not achieve a significant effect on air deodorization. In particular, it is difficult to apply because the sterilization ability of the floor space such as urinals and the surrounding bottom surface of the main pollutant is poor.

In addition, even in the case of the shoe box to store the shoes caused by the smell and odor leaked from the shoe storage to the outside to give the user an unpleasant, such smell is not sweaty and ventilated from the foot when wearing As the breeding is carried out by the bacteria that grow in the environment, it has become the cause of odor in the shoe box.

In order to clean shoes stored in these shoe racks, they are washed, deodorant or newspaper is used for management.However, in the case of washing, it is difficult to apply to shoes using leather materials, and to use deodorant or newspaper. Since it is difficult to completely and continuously remove the bacteria which is the source of the odor, it cannot have the effect of the continuous odor removal.

In addition, when ultraviolet rays are used for sterilization of shoes, discoloration and cracks are likely to occur in the manufacture of shoes, such that the use thereof is not appropriate.

The transparent cover 11 is far from the light source unit 20 fixed to the inside of the module case 10 in the optical axis direction. It can be assembled to move so as to vary the focal length to the source of contamination where bacteria and fungi are generated while being close or close.

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

That is, when the transparent cover 11 is made of a diffusion lens, the emission angle of the mixed light in which the purple light and the ultraviolet light are respectively generated in the purple LED 21 and the ultraviolet LED 22 is diffused to prevent the source of contamination. Wide range of irradiation can increase sterilization range.

In addition, when the transparent cover 11 is made of a condensing lens, it is condensed by narrowing the emission angle of the mixed light in which the purple light and the ultraviolet light generated by the purple LED 21 and the ultraviolet LED 22, respectively, are narrowed. The mixed light can sterilize the pollutant by increasing the sterilization 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 an alternating current to a direct current in accordance with the light emission driving characteristics of the light emitting unit LED.
