A phosphor may be a substance that emits fluorescence when irradiated with light, radiation, etc. When a phosphor receives energy from the outside, free electrons and holes are formed, changing to a high energy level, and the energy can be released as it returns to a stable state.

In this way, the phosphor can emit light externally by visible light, ultraviolet rays, X-rays, cathode rays, infrared rays, electric radiation, etc. Here, the phosphor may be configured to receive energy through ultraviolet rays and emit energy as ultraviolet rays of different wavelengths.

Gas that generates ultraviolet rays through discharge may be accommodated inside the first panel 11 and the second panel 12. Noble gases, etc. can be used as gases that emit ultraviolet rays through discharge. An ‘excimer (excited dimer)’ is created in the ground state. The excimer that has entered an excited state (excited state, exited) due to high-voltage discharge is in an unstable state and immediately returns to the ground state, and in this process, it emits ultraviolet light.

More specifically, glass frit sealing paste is manufactured by mixing glass frit, a microporous glass that allows gas or liquid to pass through, binder resin, and solvent. You can. Glass frit can have porous properties by sintering with glass particles.

Panel 10 may be made of a dielectric. Since the panel 10 is made of a dielectric, high voltage can be applied to the discharge space 50 through the external electrode 20, and ultraviolet rays can be generated by rare gases inside the discharge space 50.

The spacer 60 may space the first panel 11 and the second panel 12 from each other.

That is, as the first panel 11 and the second panel 12 extend in the third direction (x direction) or the direction perpendicular to the third direction (z direction, not shown), the first panel 11 It may be bent to face the second panel 12, and the second panel 12 may be bent to face the first panel 11.

The spacer 60 is provided between the first panel 11 and the second panel 12 to prevent the first panel 11 and the second panel 12 from becoming close to each other. Due to the structure of the spacer 60, the encapsulated gas inside the discharge space 50 is sufficiently discharged and passes through the first panel 11 and the second panel 12 in the first direction (y direction) and the second direction (- y direction) UV irradiation in both directions can be easily performed. That is, the durability of the sterilizing device 1 can be improved.

Afterwards, air, gas, vapor, etc. within the discharge space 50 can be exhausted to the outside and then sealed to seal the discharge space 50 . Thereafter, the pair of external electrodes 20 may be coated on the

outer surfaces

11a and 12a of the panel 10. However, the method by which the sterilizing device 1 is manufactured is not limited to the above sequence.

Additionally, the phosphor layer 40 can be divided into several phosphor layers according to the irradiated wavelength to suit the user's desired purpose.

UV-C ultraviolet rays can sterilize 99.9% of bacteria or viruses. More specifically, the DNA and RNA molecular structures of bacteria in the air in the first direction (y-direction) of the sterilizing device 1 may be damaged so that the bacteria cannot reproduce. In addition, UV-C can be an environmentally friendly light because it does not contain chemicals or mercury, and can be a light source with relatively long durability and lifespan. Using this principle, UV-C ultraviolet rays can be used for air sterilization purposes.

UV-C ultraviolet rays can also be used to disinfect water. For example, it can be used to disinfect drinking water, waste water, process water, etc., and can also be used to disinfect transportation belts or packaging materials. It can also be used to reduce mold growth and pathogens when growing plants.

Some of the ultraviolet rays generated in the discharge space 50 are converted into the wavelength range of UV-A (315-400 nm) while passing through the first phosphor layer 41 and sent in the second direction (-y) through the second panel 12. direction) can be investigated.

Additionally, UV-A ultraviolet rays can be used for tanning or pest control purposes.

Ultraviolet rays from UV-A can be used for deodorizing purposes. UV-A ultraviolet rays can be used for deodorization by using an oxidation reaction with a photocatalytic filter (90, see FIG. 5).

According to the spirit of the present disclosure, since UV-C and UV-A ultraviolet rays can be irradiated in both directions at the same time, air sterilization and deodorization can be achieved simultaneously with only one configuration rather than two configurations.

Through this series of processes, the sterilizing device (1) can irradiate UV-C ultraviolet rays and UV-A ultraviolet rays in both directions, and just one configuration of the sterilizing device (1) can achieve sterilizing performance and harmful effects on bacteria and viruses. The deodorizing performance of removing gas can be achieved at the same time.

If sterilization performance and deodorization performance are achieved simultaneously, cost and space savings can be achieved compared to the case of two configurations.

The electronic device may include a control unit (not shown). The control unit can drive the blowing fan 80 and can also apply high voltage to the

external electrodes

21 and 22 through an external power source. In addition, although not shown in the drawing, the inlet or outlet can be opened and closed.

When the blowing fan 80 is driven according to a signal from the control unit, external air may flow into the electronic device through the inlet. In response to this, a high voltage is applied to the discharge space 50 through a pair of

external electrodes

21 and 22 according to a signal from the control unit, so that the rare gas can generate ultraviolet rays. The ultraviolet rays generated by the rare gas pass through the third phosphor layer 43 and the first phosphor layer 41 of the sterilizing device 1 and are converted into ultraviolet rays of UV-C and UV-A, and are then transmitted to the first panel 11 and the first panel 11. UV-C ultraviolet rays are irradiated in the first direction (y direction) of the sterilizing device 1 through the second panel 12, and at the same time, UV-A rays are irradiated in the second direction (-y direction) of the sterilizing device 1. Ultraviolet rays may be irradiated.

In this way, the user can drive the blowing fan 80 and the sterilizing device 1 for a desired time, and such control can be performed by the controller.

However, the arrangement of this sterilizing device 1 is not limited to FIG. 5, and the purpose of the sterilizing device 1 shown in FIGS. 3 and 4 may also be used correspondingly.

In the above, specific embodiments are shown and described. However, it is not limited to the above-mentioned embodiments, and those skilled in the art can make various changes without departing from the gist of the technical idea of the invention as set forth in the claims below. .
