Recently, the use of bottled water or water purifiers (20) has become common because drinking water is not used as drinking water because it is difficult to supply clean water due to severe pollution of water sources.

  When using the water dispenser (10), water ionizer (30), water purifier (20) in each home, institution, or office, germs of hands and floating bacteria or dust from outside are buried at the entrance of the water tap (50), Since the water tap 50 and the food is in contact with the cup ramen to eat the water tap 50 is always inevitably a large amount of bacteria.

The present invention relates to being able to effectively sterilize and dry the water tap 50 using the light of a semiconductor ultraviolet light and an infrared light emitting diode (LED) lamp as described above. Existing sterilizing lamps are Korean Patent Application Publication No. 2001-92279 (ultraviolet lamps and sterilizers and cleaning devices using the lamps) and registered Utility Model Publication No. 20-0365581 Utility Model Publication No. 219591 About 10 technologies, such as (sterilization deodorizing ultraviolet lamp lighting device), have been registered and applied as prior art.

However, the germicidal lamp device as described above is a fluorescent lamp type, and the circuit configuration is complicated and the heat generation (more than about 60 degrees) is high, so that the failure rate is high, the lamp life is short, the power consumption is excessive, and the volume is large, so that the size of the water tap is large. Cursors are unsightly and constrained by the installation space, and the light is intense, which has the disadvantage of promoting hardening and corrosion of the cornea and the faucet of the human eye.

The present invention is to replace the problems and disadvantages of the above technology of the water purifier 20 or bottled water device 10, the ion water receiver 30 with a small-scale semiconductor sterilization ultraviolet LED (LED) lamp and infrared (LED) lamp As a water faucet 50, LED infrared UV lamp with long lifespan with excellent sterilization effect, easy to use, small volume, energy saving and manufacturing cost, anti-glare by UV lamp and proper sterilization effect The water purifier (20) or bottled water (10) of the new structure using the water tap 50 sterilization apparatus of the ionizer 30 will be described as follows.

LED, the acronym for 'Light Emitting Diode', began to be studied in the early 1960's and commercialized since the late 60's. LEDs were noted for their outstanding characteristics such as excellent vibration resistance, high reliability, and low power consumption. Due to the burden, it was initially used in a very small number of fields such as display lamps in spacecraft.

In principle, the light emitting principle of the LED is that when the electrical energy is applied to the light emitting device located inside the LED, the light emitting device converts the electrical energy into light and outputs the light.

All matter is made up of atoms, and there is a nucleus inside the atom, and the electrons spinning around form an orbit. As the orbit moves away from the nucleus, the orbiting electron must have more energy.

When the electrons in the low orbit receive energy from the outside, they jump up to the high orbit, and the electrons that remain unstable in the high orbit release the energy when going down the orbit, which is to control the emitted energy in the form of light. LED.

LED devices have a difference in the level of electrons going up and down depending on the type of material used, and this level difference leads to a difference in energy generated.

After all, light produced at low energy levels in the same light is red with long wavelengths, and light at high energy levels in blue with short wavelengths.

In the end, the combination of three-way index red (R), green (G), and blue (B) elements creates color. The first commercially available LED is a red LED developed using a wafer called gallium arsenide (GaAs) or aluminum arsenide (AlAs) around 68. Since then, Monsanto has applied for the crystal growth method of gallium arsenide phosphide (GaAsP), and has been researching and commercializing it mainly in the United States.

Since the development of heterojunction red LEDs with GaAlAs grown on GaAs substrates, research has been conducted in Japan in the 80s, and red LEDs using GaAlAs materials, which are high-brightness LEDs, have been commercialized. Green LEDs made of Al GaAs were in the spotlight with higher levels than incandescent bulbs, which recorded only 1% energy conversion efficiency.

Since then, research on new materials has continued, and recently, Japan has been known to secure higher brightness efficiency than incandescent bulbs due to the progress of compound semiconductor thin film growth technology of four-component composition such as indium gallium aluminum phosphide (InGaAlP).

In the case of green LEDs, aluminum phosphide (Alp) and gallium phosphorus (Gap) are the best, but Alp is easy to oxidize, and development has been attempted around the gap, and semiconductors produced by these materials are indirect transition type semiconductors, so the luminous efficiency is improved. Although it was difficult to improve the green light source, indium gallium nitrite (Incan) succeeded in developing thin film growth technology for a new crystal, and high brightness, green light LED was born in the world.

In the 90s, the development of indium gallium aluminum phosphide (InGaAlP wafers) opened the door to the commercialization of ultra-bright red and orange LEDs.

Blue is the latest of the three elements that make up an LED. The blue LED began the so-called blue LED era around 1993, when Nichia Chemical released a high-brightness blue LED made of indium gallium nitride (Ingan).

Nichia, in 1995, developed a high-brightness green LED and solved the long-standing desire of mankind to develop a low-power light source. As a result, all three colors of red, green, and blue LEDs were commercialized, and the first button for full colorization of the LED application market was put.

In 1996, a white LED with fluorescent material added to a blue LED was developed.In 2000, a high-brightness red LED appeared in the world, exceeding 100 ㏐ / W (lumens), which is much higher than the existing fluorescent light source. .

Now, more than a century after the birth of the Edison bulb, let's take a look at the mechanism by which light-emitting diodes, or LEDs, are the basis of semiconductor lighting to replace them.

LEDs are basically semiconductor PNU junction diodes. Rather than a silicon PN junction, a group III-V compound semiconductor PN junction is mainly used in which elements of group III and group V are combined on an element periodic table. This is because the group III-V compound semiconductor is a direct transition material and is a material having a light emission efficiency close to 100% (about 10,000 times higher than that of silicon).

 All matter, including semiconductors, consists of the nucleus of charge and electrons of charge. P-type semiconductors can be understood as semiconductors with voids that are not filled with electrons. This vacancy is a relatively positive charge because there is no electron in the place where the electron should be, which is called a hole.

 P-type semiconductors have a lot of holes in the valence band of home appliances.

 In contrast, an N-type semiconductor is a semiconductor in which extra electrons that do not participate in a covalent bond of a crystal are filled in a conduction band.

 The former is like water, so it's going to go low. When these P and N semiconductors are bonded and applied with voltage, holes in the P-type semiconductor are directed toward the N-type semiconductor and collected in the middle layer.

 In contrast, electrons in N-type semiconductors move toward P-type semiconductors and collect in the middle of the lowest point of the conduction band, and these electrons naturally fall into the vacancy (holes) of the consumer electronics band. It emits energy as much as the energy gap. This phenomenon is called the recombination process of electrons and holes. At this time, energy is mainly emitted in the form of heat or light, and when it is emitted in the form of light, it becomes an LED.

At this time, electrons, holes, and light must all be seen as particles. Whenever a pair of electrons and holes are recombined and disappeared, light particles come out one by one, and the current flowing through this diode is the number of holes and electron pairs put in the battery for 1 second. Since the number of light particles, or the light output, is proportional to the current.

Unlike the incandescent light coming from a hot object like the filament of an incandescent light bulb, it is a cold light that does not heat up because only the energy of the electrons is converted into light.

 Incandescent emits light in very wide wavelength bands simultaneously, whereas LED light only emits light in a specific wavelength range, which corresponds to the energy difference between the conduction band and the consumer electronics band. Therefore, it is possible to make semiconductors of various materials composition and characteristics by mixing various elements of group III and group V. By utilizing the difference in energy band gap which is inherent in group III-V compound semiconductor, It is possible to selectively come out over a wide range from the infrared, visible to the ultraviolet of the invention.

As the most basic optical characteristic of the light emitting diode (LED), the light intensity (unit: candela, cd) is used in the light emitting diode (LED) in the visible light region. Luminance is expressed in llm / sr as the luminous flux per unit angle (steradian, sr), and luminance is expressed as luminous intensity per unit area, where 1 cd is the radiance of the light source emitting monochromatic light at 555 nm. When it is 1/683 W per unit solid angle, it shows the luminance in that direction.

Or, the sensitivity of vision, or brightness of the human eye, is determined according to the wavelength. The reference value is 1, based on 683 lumens of 555 nm (1 nm = 10-9 m) of green light showing the highest sensitivity in the human eye. At this time, 470 nm blue is 62 lumens, and the sensitivity is 0.1, and 625 nm red is 219 lumens, 0.3.

The main evaluation factor for determining visible LED performance is Luminous Efficiency, expressed in lumens per watt (lm / W). This corresponds to wall-plug efficiency (light output / input electrical power) considering the human eye's sensitivity.

As described above, the present invention relates to a sterilizing apparatus for a water tap 50 through which water from a water purifier 20 or a mineral water dispenser 10 or an ionizer 30 is discharged using a semiconductor ultraviolet light and an infrared light emitting diode (LED) lamp. Water faucet (50) that can effectively sterilize and dry the water faucet (50) by attaching ultra-small semiconductor sterilizing ultraviolet LED (LED) lamp and infrared (LED) lamp to replace the conventional germicidal fluorescent UV lamp. The sterilization drying device is more specifically related to a sterilizing device having a new structure having excellent sterilization effect, easy to use, small in volume, energy saving and manufacturing cost, glare and long life.

 Conventional sterilizers all use a fluorescent lamp-type ultraviolet lamp or ozone generator

 Compared with sterilization effect, it has strong glare and stimulates the human respiratory system and attaches the choke lamp and stabilizer to light up the fluorescent lamp, which is bulky and uses a fluorescent type UV lamp which consumes a lot of power and ozone harmful to the body. In the present invention, the ultra-violet and infrared LED lamps are emitted of the water tap 50

Attached to the hollow portion 200 relates to a water tap 50 sterilizing apparatus that can more effectively sterilize the water tap 50 of the water purifier 20 or the bottled water 10 and the ionizer 30.

The present invention relates to a water tap 50 installed with an LED installed with a function of sterilizing and drying the water tap 50 of the water purifier 20 or the bottled water 10 and the ionizer 30 as described above. The purpose of the present invention is to effectively sterilize and dry the water faucet 50 by attaching the LED ultraviolet ray and the infrared lamp which have excellent antimicrobial power, germicidal power and sustainability to increase the health and hygiene of the people.

  The present invention is excellent in disinfection effect, easy to use, small in volume, easy to install, energy saving and manufacturing cost are reduced, anti-glare by UV lamp, protection of cornea, long-life durability of semiconductor ultraviolet LED, lamp By sterilizing the water tap 50 discharged from the water purifier 20 or the bottled water 10, the ionizer 30, and has the advantage of drying it quickly using an infrared LED lamp.

The present invention relates to a device capable of effectively sterilizing and drying the water tap 50 using the light of a semiconductor ultraviolet ray and an infrared light emitting diode (LED) lamp as described above. As described above, the present invention relates to an LED lamp which is a core component of the present invention. The more detailed description is as follows.

A small number of careers (electrons or holes) injected using a p-n junction structure of a semiconductor are produced, and the light emitted by recombination thereof is called a light emitting diode (LED).

The luminescence phenomena that occur when a voltage is applied to a semiconductor is called electroluminescence (electro long emission), and it originates from the observation of luminescence of silicon carbide crystals in 1923. In 1923, the high luminescence efficiency at the gallium arsenide pn junction was discovered. Since then, the research has been actively conducted. The LED is divided as follows.

1. LED is by recombination of free carriers and 2, by recombination at impurity emission centers.

At 1, the emission wavelength is approximately equal to ch / Eg (c is the luminous flux, h is Planck's constant, EG energy width), and in the case of gallium arsenide, it becomes near-infrared light of about 900 nm and phosphorus at gallium-arsenic-phosphorus. As EG increases with increasing content, it becomes a visible light emitting diode.

2, the emission wavelength is different depending on the type of impurities added to the semiconductor. In the case of gallium phosphide, the emission of zinc and oxygen atoms is red (wavelength 700 nm), and the emission of nitrogen atoms is green (wavelength 550 nm) and emission Diodes are smaller than conventional light sources, have a long lifetime, and have low power and good efficiency because electrical energy is directly converted into light energy.

In addition, because of high speed response, it is used for display lamps of various kinds of electronic devices such as automobile instrumentation, light source for optical communication, card reader of numeric display device or calculator, and the injection type semiconductor laser is a kind of light emitting diode with high injection density. Distributions can occur and produce coherent light.

The color of the LED light is basically white like sunlight, red, blue, yellow, green or some mixture of red, blue and green together, and there are also LED lamps that generate ultraviolet and infrared light of the present invention. It can also have the effect of sterilizing and circulating harmful air in bathrooms or toilets. The LED element is a structure in which nitrogen (N), gallium (Ga), and indium (In) are disposed in a nano (one billionth) meter structure. According to the mixture composition ratio, LEDs using various colors and nitride semiconductors can make not only the three primary colors of light but also infrared ultraviolet rays.

A US team was able to reduce the concentration of E.Colin bacteria in water by less than one-hundredth of a million using 280nm light from GAN-based UV LEDs. It was first reported that a water sample was exposed to 50 microwatts of light from two ultraviolet LEDs, indicating that the UV LED light source is very strong in direct sterilization.

The experiment was conducted at the University of Maine with the use of ultraviolet LEDs from Hydro-Photon in the United States and the research team of Professor Shoji Nakam at the University of California at Santa Barbara. It turns out that anything with RNA can be killed, which is the first result of a direct bactericidal effect by UV-emitting LEDs.

These UV-emitting LED light sources offer several advantages over mercury and fluorescent UVs, allowing LED UV lamps to turn on instantly without the need for choke lamps and ballasts to light conventional fluorescent UV lamps. It is cheaper, easier to carry, and has the advantage of experimentally higher efficiency.
