The present invention relates to a therapeutic device using light, and more particularly, to a phototherapy device that can treat various diseases using ultraviolet light and visible light.

In general, light transmitted from the sun includes visible light, infrared rays outside red of visible light, and ultraviolet rays outside purple.

Visible rays have a wavelength in the visible range of the human eye, and the wavelength range is approximately 400 to 700 nm. In visible light, the change of properties according to the wavelength appears in each color, and the wavelength becomes shorter from red to purple. In the case of monochromatic light, 700 to 610 nm appears red, 610 to 590 nm orange, 590 to 570 nm yellow, 570 to 500 nm green, 500 to 450 nm blue, and 450 to 400 nm purple.

Infrared rays are called infrared rays because they are farther outward than the end of the red spectrum as described above, and have a wavelength longer than visible light, and the wavelength range is approximately 750 to 1,000,000 nm (0.75 μm to 1 mm). Among these, infrared rays with wavelengths between 750 and 3,000 nm (0.75 to 3 μm) are called near infrared rays, and infrared rays between 3,000 and 25,000 nm (3 to 25 μm) are called general infrared rays. It is called far infrared. These infrared rays are characterized by having a stronger heat action than visible or ultraviolet rays, and are therefore also called hot rays.

Ultraviolet rays (Ultraviolet rays), as described above, because it is outside the end of the purple spectrum is called ultraviolet light is shorter than visible light, the wavelength range is approximately 10 ~ 400nm. These ultraviolet rays are classified into ultraviolet rays A, ultraviolet rays B, and ultraviolet rays C according to the wavelength range. If the wavelength range is 315 to 400 nm, the ultraviolet rays A (UV-A), and if the wavelength ranges between 280 and 315 nm, the ultraviolet rays B (UV- B), it is classified as ultraviolet C (UV-C) if it is between 100 and 280 nm.

Here, a light emitting diode or a laser diode is used as the light emitter 100. The light emitted from the light emitting diodes or the laser diodes is controlled by the controller 400 and irradiated to the treatment site. In this case, the wavelength of the light irradiated to the treatment site is 280 to 530 nm and the width of the wavelength is 30 nm.

At this time, the light therapy device of the present invention, as described above, is provided with one or more light emitting bodies 100 having different wavelength ranges. Release may result in additional therapeutic effects.

If the dose is 20%, 30% or 50%, respectively, another therapeutic effect can be obtained.

In addition, after installing at least one light emitter having a wavelength range different from each other in the phototherapy device, to emit light of a desired wavelength, only the corresponding light emitter is turned on and used.

For example, when a light therapy device having a light emitting device that emits light of 280 nm, 350 nm, 480 nm, and 500 nm is intended to emit light having a wavelength range of 280 to 350 nm, 280 nm and 350 nm may be used.

FIG. 2 is a graph showing the survival rate of P. acnes according to the irradiation time and the number of irradiation of light having a wavelength of 370 nm, and targets Acne bacteria, a major factor causing acne. Light emitting diodes or laser diodes emitting wavelengths of nm were used. In addition, the wavelength range was adjusted to 340 ~ 370nm (ultraviolet wavelength range) through the control unit and the irradiation time was 6hr.

As shown in FIG. 2, it is understood that the longer the irradiation time of the light beam or the more the number of irradiation times of the light beam, the lower the survival rate of the bacterium. Survival rate of Pi. Acne was significantly different in the control group irradiated twice or irradiated with light only once compared to the control group irradiated with no light or once irradiated with light. In particular, the control group irradiated twice with light or once with 24 hours of irradiation showed that the survival rate of Piacne bacteria was less than 20% from day 2 (24hr) and approached 0% from day 3 (36hr). .

In the control group irradiated with light once compared with the control group irradiated with light, the survival rate of A. acne bacteria decreases for a certain period of time (1 day, 24hr), but then increases again. On the other hand, in the control group irradiated twice with light, the survival rate of P. acne begins to decrease gradually, and it can be seen that less than 20% on one day (24hr).

In this case, the wavelength range is in the visible light region.

As shown in FIG. 4, it can be seen that the longer the irradiation time of the light beam or the more the number of irradiation times of the light beam, the fewer the number of Acnes bacteria per unit volume. The control group irradiated two or more rays or irradiated with a single ray for 24hr compared to the control group which did not irradiate the light or irradiated with light once, but irradiated with the light for 24hr, showed that the number of Acne bacteria was reduced per unit volume. 36hr) shows that the number is close to zero.

FIG. 5 is a graph showing the survival rate of the Acactes bacterium according to the irradiation time and the number of irradiation times of a light beam having a wavelength of 470 nm. A light emitting diode or a laser diode emitting a wavelength of 470 nm was used. It was adjusted to 450 ~ 480nm (visible light wavelength range) and irradiated for 6hr.

As shown in FIG. 5, the longer the irradiation time of the light beam or the more the number of irradiation times of the light beam, the lower the survival rate of the bacteria Acne. The survival rate of Piacne bacteria was significantly different from the control group irradiated with light twice or more times compared to the control group irradiated with light once or irradiated with light once but irradiated twice with 24 hours, especially 2 days (24hr). It can be seen that the survival rate is 20% or less.

On the other hand, in the case of the control group irradiated with light once, the survival rate of Piacnes bacteria increases after decreasing a certain amount, and it can be seen that again from 4 days (48hr). In addition, the control group irradiated with light once but irradiated with 24 hrs, the survival rate of the Acne bacterium decreased from 2 days (48 hrs) and after 4 days (48 hrs), the survival rate was 50% or less.

FIG. 6 is a graph showing the survival rate of S. aureus according to the irradiation time and the number of irradiation times of the light having a wavelength of 505 nm, and targeted to staphylococcus aureus, which is a major factor causing food poisoning, purulent and atopy. A light emitting diode or a laser diode emitting a wavelength of ㎚ was used and the wavelength range was adjusted to 500 ~ 530 nm (visible light wavelength range) through a control unit and irradiated for 6hr.

As shown in FIG. 6, the longer the irradiation time of the light beam or the higher the number of irradiation times of the light beam, the lower the survival rate of Staphylococcus aureus. The survival rate of Staphylococcus aureus in the control group that was irradiated with light once or twice compared to the control group that did not irradiate light was significantly different. Especially, from 2 days (24hr), the survival rate was 20% or less and after 3 days (36hr) You can see that it is close to%.

On the other hand, the control group irradiated with light three times did not show a reaction until 2 days (24hr), after which the survival rate of Staphylococcus aureus sharply decreased, it can be seen that from 3 days (36hr) approached 0%.

FIG. 7 is a graph showing the survival rate of Piacnes bacteria according to the irradiation time and the number of irradiation times of a light beam having a wavelength of 505 nm. The light emitting diodes or laser diodes that target Piacnes bacteria and emit a wavelength of 505 nm are shown in FIG. The wavelength range was adjusted to 500 to 515 nm (visible light wavelength range) through a control unit and irradiated for 6hr.

As shown in FIG. 7, the longer the irradiation time of the light beam or the more the number of irradiation times of the light beam, the lower the survival rate of the bacterium. Compared with the control group irradiated with light, the survival rate of Piacnes bacteria of the control group irradiated with the light one or more times shows a significant difference, and after 3 days (24hr), the survival rate is 60% or less. In particular, it can be confirmed that Pi Aknese viability of the control group irradiated twice with light rays is 30% or less after 3 days (24hr).
