Description

Device for scalp care {SCALP CARE DEVICE}

The present invention relates to a hair loss prevention device for preventing hair loss by using red light and blue light.

In a normal person, 80-90% of the hair follicles of the entire hair grow, and the remaining 10% rest or fall out. In other words, everyone loses an average of 50 to 100 hairs per day.

In addition, even in a normal person, there are many cases in which hair loss begins due to genetic causes as people age.

However, if the growth of hair follicles is slowed due to acquired causes, the hair becomes thinner and more hair falls out than the hair that grows. In that case, the period of hair loss may be advanced further or the range of hair loss may be enlarged.

A specific configuration of the main body sheet 100 included in the apparatus 1 for scalp care according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3 . 1 is a view showing a state in which a light emitting unit is disposed on the first surface of the main body sheet according to an embodiment of the present invention, and FIG. 2 is a control unit on the second surface of the main body sheet according to an embodiment of the present invention. It is a view showing the arrangement state, and FIG. 3 is a view showing patterns formed on the first surface and the second surface of the main body sheet of the device for scalp care according to an embodiment of the present invention.

The body sheet 100 is made of a flat flexible printed circuit board, and any one surface of both surfaces of the body sheet 100 is referred to as a first surface 101 , and the other surface is referred to as a second surface. This is referred to as the face 102 .

On the first surface 101 , a plurality of light emitting units 200 for irradiating light are disposed over the entire area. Specifically, when the first surface 101 of the plurality of light emitting units faces the wearer's scalp, an appropriate number of light emitting units may be arranged at a predetermined interval so that light can be evenly irradiated to the scalp area covered by the first surface. .

The light emitting unit 200 includes a blue light emitting device (not shown) for irradiating blue light and a red light emitting device (not shown) for irradiating red light.

The blue light emitting device may be composed of a light emitting diode (LED) emitting blue light having a wavelength of 405 nm to 415 nm, and the red light emitting device may be composed of a light emitting diode emitting red light having a wavelength of 650 nm to 660 nm. there is.

Red light having a wavelength of 650 nm to 660 nm penetrates up to 2 mm under the skin to increase cell synthesis of hair follicle cells, and also increases blood flow to increase nutrient supply to hair follicle cells. Therefore, when red light having a wavelength of 650 nm to 660 nm is irradiated to the scalp, the thinned hair becomes thick and the speed of new hair growth can be increased.

Blue light having a wavelength of 405 nm to 415 nm can kill bacteria by so-called porphyrin reaction decomposition, but has no harmful effect on the human body. That is, the blue light having a wavelength of 405 nm to 415 nm is different from the UV-C wavelength harmful to the human body because it is a wavelength within the visible ray region.

Specifically, one of the various factors that cause scalp inflammation is the reproduction of bacteria and bacteria, especially when bacteria grow well in a high-temperature and high-humidity environment, do not wash and dry hair well, or are exposed to a lot of polluted environments, and skin immunity. Bacteria are more easily generated when the hair falls, and when blue light having a wavelength of 405 nm to 415 nm is irradiated to the scalp, it helps to remove bacteria and bacteria that adversely affect the scalp, such as dandruff.

Meanwhile, the light emitting unit 200 may further include an infrared light emitting device (not shown) for irradiating infrared rays.

A control unit 300 for supplying and controlling power to the plurality of light emitting units 200 is disposed on the second surface 102 of the body sheet 100 . Placing the control unit 300 on the first surface opposite to the scalp when worn can give a feeling of foreign body when worn by circuit parts included in the control unit 300, and a separate control unit (in addition to the light emitting unit 200) Since it is necessary to secure an area in which the 300) is disposed, it is not preferable to increase the overall volume of the body sheet 100 .

The control unit 300 supplies and controls power to the light emitting unit 200 . Specifically, it is possible to control only the blue light emitting device of the light emitting unit 200 to emit light or to control only the red light emitting device to emit light, and it is possible to control the blue light emitting device and the red light emitting device to emit light at the same time.

In addition, the intensity of light of each of the blue light emitting device and the red light emitting device may be adjusted in stages. For example, the intensity of light of each of the blue light emitting element and the red light emitting element may be adjusted in three steps according to the sensitivity of the skin.
