First, a structure of the LED mask device 10 according to the present invention will be described with reference to FIG. 1.

The LED mask device 10 according to the present invention to which the surface light source structure is applied includes a mask body 11, an LED light source unit 12 and a reflector 13, and may further include a housing 14 and a rear cover 15. have.

The mask body 11 forms the entire skeleton of the LED mask device 10, and is formed to cover the user's face when the user wears it, so that the outer surface is exposed to the outside. The material and structure of the mask body 11 can be applied in various ways within a known technology, and a detailed description thereof will be omitted since it is not a core structure of the present invention.

The LED light source unit 12 may apply an LED (Light Emitting Diode) package, and a point light source is formed to irradiate the inner surface of the mask body 11. A plurality of LED light source units 12 may be installed along side edges of the mask body 11.

At this time, the LED light source unit 12 is installed inside the housing 14, and the housing has a shape in which all sides except one side are closed. That is, the light irradiated from the LED light source 12 is irradiated to the inner surface of the mask body 11 only through the open side (inner direction of the LED mask). The housing 14 is manufactured in a plurality according to the size of one LED light source unit 12 to accommodate one LED light source unit 12, or a plurality of LED light source units 12 installed along the circumference of the mask body 11 It can also be manufactured as a single body formed along the circumference of the mask body 11 so that all is accommodated. When the housing 14 structure is applied, light leakage can be blocked and light loss can be reduced.

FIG. 2 shows a portion'A' of FIG. 1 and shows an angle adjustment state of the housing 14.

Referring to FIG. 2, the housing 14 is mounted inside the mask body 11, and the irradiation angle of the LED light source 12 varies according to the mounting angle of the housing 14. That is, by adjusting the surface angle of the housing 14 coupled to the inner surface of the mask body 11, the surface uniformity of the LED light source unit 12 with respect to light irradiation can be adjusted through the'θ' angle adjustment.

The reflective plate 13 is mounted on the inner surface of the mask body 11 and reflects the light irradiated from the LED light source unit 12 to emit light toward the user's face. To this end, the LED light source unit 12 may be installed along the circumference of the reflective plate 13 formed on the inner surface of the mask body 11.

Meanwhile, the reflector 13 applied to the present invention also serves as a conventional light guide plate, and the point light source irradiated from the LED light source unit 12 is converted into a surface light source through the reflector 13 and irradiated to the user's face. Therefore, referring to FIG. 3, at least one of an intaglio or embossed pattern for irradiating light irradiated from the LED light source unit 12 in the direction of the user's face with a uniform amount of light may be formed on the reflective plate 13. . The light irradiated from the LED light source unit 12 through an intaglio or embossed pattern is reflected at least once and emitted toward the user's face.

In addition, the LED light source unit 12 may be installed continuously or non-continuously along the circumference of the mask body 11, and may be installed at equal intervals or at irregular intervals. In addition, to increase the amount of light, the LED light source unit 12 may further include a lens having a narrow viewing angle. That is, the amount of light, light uniformity, and light luminance may be increased by using the pattern of the reflector 13, the position of the LED light source unit 12 and the light irradiation angle.

Meanwhile, the mask body 11 is further provided with a rear cover 15. The rear cover 15 places the housing 14 inside the mask body 11 and closes the inner surface of the mask body 11, and is located closest to the user's face. Accordingly, light reflected in the direction of the user's face through the reflector 13 is irradiated to the user's face through the rear cover 15.

The rear cover 15 may be coupled to the mask body 11 and a substrate (not shown) and formed to cover one surface of the substrate. The mask body 11 and the rear cover 15 prevent water or other foreign substances from penetrating into the substrate disposed therein, thereby preventing failure or damage of the LED light source unit 12 or other components disposed on the substrate. Can be prevented.

In addition, when the user wears the LED mask device 10, the rear cover 15 is positioned between the substrate and the user's skin to prevent the user's skin from contacting the substrate.

The rear cover 15 may be implemented with a transparent plastic or acrylic material in order to irradiate light emitted from the LED light source 12 provided on the substrate to the user's facial skin. In particular, the rear cover 15 may have a structure so that the light emitted from the LED light source unit 12 is evenly irradiated to the skin or the light is concentrated to a specific area.

Like the mask body 11 and the substrate, the rear cover 15 may also include an opening (not shown) for securing a user's view when worn by the user.

Meanwhile, although not shown, at least one of a lenticular surface (not shown) or a prism surface (not shown) is provided on the rear surface of the rear cover 15 located in the user's face direction, that is, the rear cover 15 close to the user's face. Either side can be formed.

The prism surface is formed in an equilateral triangular shape with a pointed end in an equilateral triangular shape, and the lenticular surface is similar to the prism surface, but refers to a surface formed with a curved end.

The light luminance can be increased through the prism surface and the lenticular surface, and visibility shielding property for the front direction of the rear cover 15 (inner direction of the mask body) can be secured. That is, since it has a shielding effect for the internal structure located between the mask body 11 and the rear cover 15, an aesthetic design effect can be obtained.

According to the present invention described above, even when the structure of the light guide plate is omitted, the point light source of the LED light source unit 12 is converted into a surface light source using only the pattern structure of the reflector 13 and the light irradiation angle of the LED light source unit 12. It can be transmitted to the face of the device, and since the light guide plate is omitted, the overall weight of the LED mask device 10 can be reduced, thereby reducing user fatigue, and lowering the manufacturing cost, thereby securing price competitiveness.

In the above, even if all the constituent elements constituting the embodiments of the present invention are described as being combined into one or operating in combination, the present invention is not necessarily limited to these embodiments. That is, within the scope of the object of the present invention, all of the constituent elements may be selectively combined and operated in one or more.
