- the second light L2 also promotes the movement of immune cells (eg, white blood cells 1110) from the dilated blood vessel 1100.
- Immune cells move to the wounded area and ingest and remove the infiltrated foreign matter, that is, the pathogen 2000.
- the immune function in the dermis SK2 is activated by the second light L2, so that the unsterilized pathogen 2000 is effectively removed by the first light L1.
- reference numeral 1120 which is not shown, denotes red blood cells.
- new cells are generated in the wound area where the pathogen has been removed by the first light L1 and the second light L2, so that the wound area gradually decreases.
- the wound is completely healed by regenerating and removing the wound, and the expanded blood vessel 1100 is contracted again.
- the light irradiation apparatus 100 may be implemented in various forms for skin treatment.

- a region of the substrate 20 facing the skin but provided with the first light sources 30 is referred to as a first region R1, and the second light sources ( Assuming that the second region R2 is provided with 40), it is illustrated that the second region R2 surrounds the first region R1.
- the surface forming the first region R1 may be concave from the surface of the second region R2 to be further away from the skin than the surface forming the second region R2. Accordingly, the second area R2 around the first light sources 30 provided in the first area R1 has a protruding shape, and light emitted from the first light sources 30 is caused by the protruding portion. The progression of light may be partially hindered.
- the light emitted from the first light sources 30 may proceed to a portion not obstructed by the protruding portion.
- the skin application area of the light emitted from the first light sources 30 may be relatively narrowed. Since the second light sources 40 are disposed at a portion protruding from the first region R1, their periphery is relatively open, and there is little restriction on the propagation direction of light. Therefore, it may be applied to a relatively wider area of the skin than the first light.
- the substrate 20 on which the first and second light sources 30 and 40 are mounted includes a first region R1 and a second region R2, and the first region (although it is illustrated that the shape varies according to R1) or the second region R2, the shape is not limited thereto.
- the substrate 20 itself may be flat or may not have a special shape, and the first and second light sources 30 and 40 and the substrate 20 according to a separate component, for example, a separate support member, etc. ) May be different.

- the light irradiation apparatus 100 may be implemented in various forms.
- 7A is a plan view of the light irradiation apparatus 100 according to an embodiment of the present invention
- FIG. 7B is a cross-sectional view taken along line B-B' of FIG. 7A.
- the light irradiation apparatus 100 may have a different shape or size of an area to which light is provided according to a shape or state of a skin or a wound.
- the light irradiation device 100 is elongated in one direction (B-B' direction in the drawing). This type of light irradiation device 100 can be used when the skin is formed long in one direction, such as an arm, or when the wound itself is formed long.
- the substrate 20 is disposed in the center and surrounds the first region R1 corresponding to the concave portion, the second region R2 corresponding to the convex portion, and the first A third region R3 that is disposed between the region R1 and the second region R2 and corresponds to an inclined portion may be included.
- the inclination of the third region R3 is formed in a direction toward the center.
- First light sources 30 may be disposed in the first and third regions R1 and R3, and second light sources 40 may be disposed in the second region R2. Since the first light sources 30 are disposed in a concave portion or inclined toward the inside, an area of the skin applied to the light emitted from the first light sources 30 may be relatively narrowed. Since the second light sources 40 are disposed at a portion protruding from the first region R1, their periphery is relatively open, and there is little restriction on the propagation direction of light. Therefore, it may be applied to a relatively wider area of the skin than the first light.

- FIG. 8 is a graph showing the sterilization effect according to the irradiation condition when light is irradiated to a wound using the conventional invention and the light irradiation device according to an embodiment of the present invention. This is a comparison of the recovery period of the wound according to the irradiation conditions when the wound is irradiated with light using the light irradiation device according to the example.
- the comparative example was not irradiated with any of the first light and the second light
- Experimental Example 1 was irradiated with ultraviolet rays using an ultraviolet light irradiation apparatus for sterilization
- Experimental Example 2 was an embodiment of the present invention.
- the first light and the second light are irradiated using the light irradiation device according to the example.
- the light source used in Experimental Example 1 was an ultraviolet light source, the ultraviolet wavelength was 254 nm, and the dose was 150 mJ/cm 2 .
- the wavelength of the first light source used in Experimental Example 2 was 410 nm and the dose amount was 120 J/cm 2
- the wavelength of the second light source was 850 nm and the dose amount was 60 J/cm 2 .
- the light of Experimental Example 1 and Experimental Example 2 was irradiated a total of 3 times for 3 consecutive days. Table 2 shows irradiation conditions when light was irradiated to a wound using a light irradiation device according to an exemplary embodiment of the present invention
- the sterilization effect according to is represented by the number of bacteria, and the number of bacteria was written on a log scale.
- the comparative example in which no light was irradiated showed a pattern in which the number of bacteria did not decrease until 14 days passed, but rather the number of bacteria increased very much between them.
- the number of bacteria continued to increase from day 1 to day 7 after being infected with bacteria by a wound, and the number of bacteria decreased again after a longer period of time.
- the reason why the number of bacteria continued to increase from Day 1 to Day 7 is judged to be the result of proliferation of bacteria in wounds and wounds rather than killing them, and it seems that the number of bacteria decreased as the bacteria were partially killed by immune action thereafter. In the case of 1, it could be seen that the number of bacteria decreased on the first day by applying ultraviolet rays to the wound.
- Example 2 the number of bacteria continuously decreases over time. It is interpreted that this is because the sterilization of bacteria in the epidermis occurs by the first light and at the same time, sterilization of bacteria in the inner side of the epidermis and the dermis occurs by promoting the immune function.
- Table 3 shows the recovery period of the wound according to the irradiation conditions when light is irradiated to the wound using the conventional invention and the light irradiation device according to an embodiment of the present invention, and shows the length of the wound over time. .
- the comparative example without irradiation with any light showed very slow recovery of the wound until 14 days passed.
- the wound recovery appeared faster than the comparative example, but still wound The recovery was slow, and even on the 14th day, the recovery was only about 50%.
- the light irradiation apparatus significantly reduces the healing period of the wound as well as the sterilization effect of the wound.
