The diffusion plate 141 changes the ultraviolet light of the point light source into the ultraviolet light of the surface light source. That is, the UVLED chip 130 emits the ultraviolet light of the point light source, and the ultraviolet light of the point light source diffuses into the ultraviolet light of the surface light source as it passes through the diffusion plate 141. A diffusion pattern is formed in the diffusion plate 141, and the ultraviolet rays of the point light sources incident on the diffusion plate 141 are diffused into the ultraviolet rays of the surface light sources according to the diffusion patterns.

7 is a view for explaining a power supply module in the sterilization apparatus shown in FIG.

Referring to FIG. 7, the power module 200 includes a power supply 210 and a driver 220.

The power supply unit 210 may receive power from an external power source and apply the power to the driving unit 220 or may provide power to the driving unit 220 as a power source. The power supply unit 210 may be a switched-mode power supply (SMPS) when the power is supplied from the outside, and may be a battery when supplied by itself.

The driver 220 serves to drive the UVLED chips 130 mounted on the substrate 120 using the power applied from the power supply 210. The driver 220 may selectively drive some or all of the plurality of UVLED chips 130 arranged on the substrate 120. As described above, the plurality of UVLED chips 130 may be uniformly arranged to emit the same wavelength, or may be a mixture of those emitting the different wavelengths. Thus, when a plurality of UVLED chips 130 emitting the same wavelength are uniformly arranged, the driving unit 220 drives only a part of the plurality of UVLED chips 130 arranged on the substrate 120 to the sterilization apparatus. Power consumption can be reduced or the intensity of the wavelength can be adjusted. In addition, when a plurality of UVLED chips 130 emitting different wavelengths are arranged in a mixed state, the driving unit 220 may include a UVLED chip emitting a required wavelength among the plurality of UVLED chips 130 arranged on the substrate 120. Only 130). To this end, the driving unit 220 includes a driving IC 221 and the peripheral component 223. The driving IC 221 includes a PWM control and a constant current according to the design. Peripheral component 223 includes a resistor or the like.

Next, the advantages of the sterilization method using the sterilization apparatus according to the embodiment of the present invention as described above will be described.

There are three types of UV rays transmitted directly from the sun to the earth: UV-A (320-360 nm), UV-B (280-320 nm), and UV-C (250-280 nm). Most of the 99% absorbed by and reaching the Earth's surface are in the form of UV-A (320-360 nm), which only causes little harm to plants, while UV-B (280-320 nm) can cause damage to plant tissues and cause skin cancer in humans. UV-C (250-280nm) can burn and kill bacteria and viruses. The ultraviolet germicidal effect is mainly caused by the UV-C region between 250 nm and 280 nm even in the ultraviolet wavelength band. UV-C is characterized by sterile ultraviolet light because DNA present in cells absorbs UV-C well.

Among UV-C, a wavelength of 253.7 nm (about 254 nm) is best absorbed by DNA, which is known to permanently damage and kill DNA, a microbial genetic material. Moreover, the wavelength which shows the highest bactericidal effect is 265 nm. The wavelength of 254nm emitted by the low pressure or high output low pressure amalgam lamp has a very high UV sterilization effect, but because it emits only 254nm wavelength due to the characteristics of the lamp, it is known that the wavelength has the highest effect. It is reported to have efficiency. This UV-C wavelength is hardly detectable because the wavelength is too short and the transmittance is weak, and the ozone layer in the earth's atmosphere completely blocks it. Thus, a sterilization device that emits ultraviolet rays can be made and artificially used for sterilization. The advantage of UV sterilization is that it can sterilize all germs, and when it is exposed to vegetables or fruits, the minerals are kept intact, there is no change in pH, it is not resistant to germs irradiated by light, and the method of use is simple and economical. I use it a lot. Such ultraviolet sterilization can sterilize fungi such as bacteria, Escherichia coli, and viruses that are harmful to the human body contaminated with air and water or contaminated with household utensils or household goods.

The UVLED chip 130 is a UV light emitting diode manufactured in the form of a semiconductor chip. Accordingly, there are the following advantages. Table 1 below is for explaining the advantages of the UVLED chip 130 according to the embodiment of the present invention compared to the conventional mercury lamp (Hg Lamp). 8A and 8B are graphs showing a spectrum emitted by a UVLED chip according to an embodiment of the present invention and a spectrum emitted by a conventional mercury lamp.

Selectable Efficiency Less than 10% At 365nm wavelength

Slower with use Fast response

Referring to Table 1, a sterilization method using UV according to the prior art uses a mercury lamp, and as shown in FIG. 8A, a mercury lamp (Hg lamp) emits multiple spectra. Accordingly, the conventional UV sterilization method must use a filter to select the required wavelength from the multiple spectra and eliminate the remaining wavelengths. On the other hand, as shown in Figure 8b, the UVLED according to the embodiment of the present invention emits only one spectrum, such UVLED can emit only the spectrum necessary for the characteristics of the semiconductor chip, it is not necessary to use a filter. For this reason, the sterilization method using the UVLED according to the embodiment of the present invention does not disperse its power like a mercury lamp according to the prior art, and thus, is more efficient than a mercury lamp.

As described above, the mercury lamp must be filtered to emit only the desired wavelength, so that the sterilization device using the mercury lamp coats the interior using a thin coating material for filtering. In addition, since the sterilization apparatus using the mercury lamp generates a lot of heat, the coating materials of the thin film melt inside the sterilization apparatus to fall into debris and the color of the light-receiving part may change when used for a long time. On the other hand, the sterilization apparatus using the UVLED does not cause the above problems.

Mercury lamps are fragile glass and are inconvenient to handle. UVLEDs, on the other hand, are semiconductors and packaged with semiconductor technology, making them very robust.

Mercury lamps contain mercury and are subject to sanctions and environmental concerns under the Restriction of Hazardous Substances Directive (RoHS), but UVLEDs are environmentally friendly because they do not contain heavy metal regulatory substances.

Mercury lamps have a lifetime of 1,000 to 20,000 hours at 70% output. Typically, mercury lamps have a lifetime of about 2000 hours. UVLEDs, on the other hand, typically have a lifetime of 50,000 hours and may have a lifetime of 100,000 hours. This can be said to have a semi-permanent life.

On / off cycling for turning on the power and for light to emit light also slows the response for mercury lamps, but UVLEDs have the advantage of responding immediately.

The sterilization apparatus using the light emitting diode according to the embodiment of the present invention as described above may be applied and used in various fields.

In the field of home appliances, a sterilizing apparatus using a light emitting diode according to an embodiment of the present invention may be employed in a cleaner, a sterilizer, a dish washer, a refrigerator, a washing machine, an air conditioner, an air cleaner, and a humidifier.
