The light emitting diodes 53 may include various types of light emitting diodes that emit near infrared light having a wavelength of 850 to 920 nm or light having a wavelength of 620 to 640 nm or visible light of red or blue color.

In general, near-infrared indicates the shortest wavelength among infrared rays, 750 ~ 3000nm, by comparing the drying rate of moisture according to the wavelength of the near infrared, the most efficient wavelength band was identified.

Figure 5 is a graph summarizing the drying experiment according to the wavelength of the near infrared, as shown in the graph to investigate the near infrared rays having different wavelengths recorded the time it takes for all 5g of water contained in the container to evaporate. In this experiment, the separation distances between the light emitting diodes irradiating near infrared rays from the vessel were the same, and the temperature and humidity of the drying chamber were kept the same during each experiment.

As can be seen through the graph, repeated experiments showed that the time taken for the water to dry is the shortest when the wavelength is 850 to 920 nm compared to other wavelength bands.

When the wavelength is over 2000nm through repeated experiments, the drying time is expected to increase, so the experiment was not conducted.

In this experiment, when the light emitting diode 53 had a wavelength of 850 to 920 nm, the drying time of the hair could be minimized to minimize hair damage caused by hot air.

The light emitting diodes 53 may also be formed to irradiate light having a wavelength of 620 to 640 nm in addition to near infrared rays.

There is a growing interest in wound healing methods using low-power lasers, and the light of a specific wavelength activates the proliferation of skin tissues, thereby increasing the healing effect of the wound very much.

Skin tissue regeneration by light of the wavelength of 620 to 640nm was confirmed through experiments.

<Experiment>

Hair was removed from the back of experimental animals (250-280g Sprague-Dawley Rat (SD-Rat), 8 weeks old adult), and the entire skin layer was removed with a circular diameter of 1cm in diameter. Eight groups, 18 in total, were prepared.

After 24 hours of stabilization after wounding, 8 groups of irradiated groups were irradiated with light, and 8 groups of untreated groups were left unirradiated, and then irradiated with skin tissue. Lamination was compared.

Table 1 below describes the light irradiation experimental conditions.

Light irradiation target group Comparative group Remarks wavelength 633 nm - Drinking water and exclusive feed were freely consumed during the experiment. Intensity of light 8 mW / ㎠ - Light irradiation time 9 days an hour a day - Wavelength type Continuous light - Temperature 24 ~ 26 ℃ 24 ~ 26 ℃

After irradiating light to the light irradiation target group for 9 days under the conditions of Table 1, the skin regeneration was confirmed.

Nine days after the trial, there was no significant difference in wound repair between the two animals. Therefore, a histological examination was performed to confirm the exact experimental results.

Tissue sections were prepared by extracting the skin with a size of 2 × 2 cm around the wound and then measuring the size of the wound through an optical microscope.

The measurement results of the long diameter of the skin defect area were summarized in Table 2 below with the average value.

division Wound Size (Mean ± Standard Deviation) (㎛) Remarks Light irradiation target group 2,107 ± 603 Comparison target group 2,428 ± 623

As can be seen from the experimental results, when the light of 633nm wavelength was irradiated, the recovery rate of the wound was faster.

Therefore, by applying the light emitting diode 53 that can irradiate light of the wavelength band to the scalp to irradiate light of 620 to 640nm wavelength can increase the healing speed of the wound, it can be expected to maintain the skin health effect have.

In addition, a light emitting diode 53 for irradiating light of a specific color of red or blue light may be applied. The light of this color stimulates the scalp, and the light emitted from the LED lamp stimulates tissue when absorbed by the human body, thereby It is known to increase the production of mitochondria by inducing metabolism. In particular, red light increases fibroblast cell growth by more than five times to increase collagen synthesis, and blue light is known to be effective in purifying the skin and inhibiting the growth of bacteria (P. Acne) that causes acne.

Therefore, even when the light emitting diode 53 for emitting red or blue light is applied, it can be expected to have a beneficial effect on the scalp.

The second terminal 55 is formed to protrude from the rear surface of the substrate 54 so as to supply power to the light emitting diodes 53 through the substrate 54, and the terminal fastening hole 44 of the support portion 41 is formed. It penetrates and protrudes a predetermined length backward.

The second terminal 55 is formed in the form of a protrusion so as to be inserted into the first terminal 16, and since the outer diameter of the second terminal 55 corresponds to the diameter of the first terminal 16, the first, The LED lamp unit 30 may be fixed to the main body 11 by the fastening force of the second terminals 16 and 55.

In this embodiment, the LED lamp unit 30 and the main body 11 are coupled to each other by the fastening force of the first and second terminals 16 and 55, but the first and second terminals 16 and 55 are coupled to each other. When the coupling force of the 55 is not sufficient, a separate coupling means for coupling the LED lamp unit 30 and the main body 11 to each other may be further provided, for example, the detachable fastening member 31 and the connecting member 15. The magnet may be installed on one side and the magnetic body may be installed on the other side to maintain the combined state of the LED lamp unit 30 and the main body 11 by magnetic force.
