Description

LED mask {LED Mask}

The present invention relates to an LED mask, and more particularly, to an LED mask that irradiates light emitted from a light source unit including red, blue, and infrared LEDs to a face through a light guide plate to obtain skin lightening, whitening, .

The phototherapy for treatment of skin diseases uses a variety of light sources such as sunlight, laser, fluorescent lamp and ultraviolet lamp to irradiate light to the skin to promote biochemical reaction in the skin, It is an optical medical technology that treats damaged skin through destruction.

The dual LED light source can be irradiated to a large area of diseased area with a suitable light output unlike a high output laser. The skin treatment technique using the LED light source is similar to the principle that sunlight is converted into plant cells through chlorophyll in plants To induce a photo-biochemical reaction between skin cells by irradiating the LED light source.

Such light therapy using an LED light source is based on the photon of an LED light source absorbed by chromospheres or photoacceptors in cell tissue and promoting cell metabolism. The light absorbed by the cells increases the synthesis of ROS and ATP in the cell tissue, and the cells exposed to red light and near-infrared light emit NO. At the appropriate time and frequency, light of a selected wavelength is absorbed by a photoreceptor, such as cytochrome c oxidase, which photodecomposes inhibitory NO, promotes enzyme activation, and promotes mitochondrial metabolism and ATP production. As a result, proteins such as hemoglobin and myoglobin release additional NO, which results from a continuous intracellular biochemical reaction.

As a result, LED light irradiation on the cell activates the overall metabolic activity of the cell and plays a major role in cell regeneration and rehabilitation. In addition, LED light irradiation promotes the production of collagen and elastin in the skin, suppresses the occurrence of wrinkles, and makes the skin moist and elastic.

In addition, the LED light irradiation can exert a considerable effect on improvement of skin diseases. For example, irradiation with LED light, particularly blue LED light, on the acne-generated skin part can eliminate the bacteria that cause acne and reduce inflammation, thereby improving the overall condition of the skin.

Light in this wavelength range is absorbed into epidermis of the skin, stimulates porphyrin, To destroy the bacteria. Light in this wavelength range is useful for the improvement of skin diseases such as acne.

In addition, the red LED 222 that emits red light mainly irradiates light having a wavelength of 630 to 640 nm, the light of this wavelength penetrates into the dermal of the skin, and about 80% of the light energy is absorbed within 2 mm do. Red light stimulates mitochondria and activates ATP production, leading to cellular turnover, superficial circulation, and anti-inflammatoryemission.

The infrared LED 223 irradiates light of an infrared wavelength band of 800 to 900 nm. The light of this wavelength band penetrates deeper into the skin than the light irradiated by the blue or red LED 222, In the skin, the temperature of the cell is increased, and the effects such as pain relief and activation of regeneration of skin cells can be expected.

3, the light source unit 200 is mounted on the side surface of the mask body 100 and irradiates light to the light guide plate 110. The light is transmitted through the light guide plate 110, It is irradiated to the wearer's face through the side.

Since the mask body 100 includes the light guide plate 110, the light emitted from the light source unit 200 is not irradiated intensively at a specific position where the LED unit 220 is installed, The light can be irradiated uniformly, and therefore, the uniform effect on the entire facial skin can be expected.

The light source unit 200 may be disposed between the mask body 100 and the light guide plate 110 to irradiate light toward the light guide plate 110 as shown in FIG.
