In particular, the LED device 220 preferably irradiates a wavelength in the range of 600 to 700 nm.

The light wavelength of the LED element 220 varies depending on the type of the photosensitive agent, and it is generally preferable to set it to 600 to 700 nm.

In this case, when the light wavelength of the LED element 220 is less than 600 nm, since only heat is applied to the skin, collagen production is effective, but the effect on the skin surface is significantly reduced.

On the contrary, when the light wavelength of the LED element 220 is greater than 700 nm, the light absorbs high water, thereby stimulating the surrounding skin, thereby degrading collagen generating ability.

In particular, it is preferable that the LED device 220 emits light having a wavelength of 630 nm, and the photosensitizer is a 5-aminolevulinic acid derivative.

This is because the 5-aminolevulinic acid derivative can maximize the skin regeneration effect by a chemical reaction in the LED device 220 that emits light of 630nm wavelength.

On the other hand, the light guide plate 230 transmits the light molecules formed and provided on the front side of the LED element 220 and serves to scatter for even irradiation on the skin.

That is, when the incident angle of the light of the LED element 220 introduced into the light guide plate 230 is less than or equal to the critical angle, total reflection occurs to spread the light throughout the light guide plate 230.

However, since the light path is generated only when the medium is changed, the scattering pattern 232 may be printed on the rear surface of the light guide plate 230, and as the constituent material of the scattering pattern 232, silicon oxide (SiO 2) is used. , PMMA (Poly Methyl Meth Acrylate) or solvent may be used.

In particular, the light incident into the light guide plate 230 is scattered while hitting the scattering pattern 232, the light produced from the light guide plate 230 has a scattering structure of a predetermined shape corresponding to the printing structure or position of the scattering pattern 232. Form.

In this case, the light guide plate 230 is usually manufactured using polymethyl methacrylate (PMMA), but is not limited thereto.

Thus, the protective window 400 is firmly fixed inside the housing 100.

In addition, the signal applying unit 300 is formed in the housing 100 and serves to apply an operation signal to the light emitting unit 200.

In this case, the signal applying unit 300 transmits a power application signal to the device circuit board 210 of the light emitting unit 200.

Here, the signal applying unit 300 includes a main circuit board 310, a switch 320, and a cap 330.

The main circuit board 310 is formed inside the housing 100 and serves to supply an electrical signal to the light emitting unit 200, in particular, the device circuit board 210.

Of course, the main circuit board 310 forms a circuit pattern to guide the flow of current, and always or intermittently receives the main power from the outside.

That is, the main circuit board 310 receives power and transmits the power to the device circuit board 210 when the main circuit board 310 is electrically connected to an external main power source or when the main circuit board 310 is electrically connected to the battery 340.

The main circuit board 310 can be transformed into various shapes and various materials.

In addition, the switch 320 is formed on the main circuit board 310, and serves to interrupt the electrical signal by repeatedly pressing.

In this case, the switch 320 is mounted on the main circuit board 310 and is mounted by various methods such as bonding or bolting.

In addition, the switch 320 is preferably a tact switch.

Of course, the switch 320 may be variously applied.

In addition, the cap 330 is in contact with the switch 320, and is formed to be exposed to the outside of the housing 100 serves to transfer the repeated pressing operation to the switch 320.

That is, the cap 330 is fitted to the housing 100 to be exposed to the outside of the housing 100, the lower side is in contact with the switch 320.

Thus, the cap 330 receives the pressing force from the user and presses the switch 320 so that power is transmitted to the device circuit board 210 through the main circuit board 310.

In one example, the main circuit board 310 is to be mounted to the lower housing 120 of the housing 100, the cap 330 is provided to protrude to the upper side of the upper housing (110).

In addition, a battery 340 for supplying power to the main circuit board 310 is mounted below the lower housing 120.

Furthermore, the housing 100, in particular, the lower housing 120 forms a support rib 352 to support the main circuit board 310, and the main circuit board 310 is fastened to the support rib 352. It is preferable to form the insertion hole 354 to insert the (356).

At this time, the support rib 352 is preferably formed integrally protruding from the inner bottom surface of the lower housing 120.

The support rib 352 is fastened to the fastening member 356 inserted into the main circuit board 310.

Thus, the main circuit board 310 passes through the insertion hole 354 to insert the fastening member 356.

Of course, the components of the signal applying unit 300 may be mounted to the housing 100 by various methods.

Accordingly, as shown in FIG. 5, a scattering pattern 232 having a predetermined shape is formed on a rear surface of the light guide plate 230 in a periodic arrangement.

When a command to emit the LED element 220 is transmitted from the signal applying unit 300, the device circuit board 210 receives the command signal and turns on the LED element 220.

Then, the light emitted from the LED element 220 and incident on the light guide plate 230 is reflected on the upper surface, that is, the emission surface and the rear surface of the light guide plate 230 and proceeds toward the end.

Each time the scattering pattern 232 is reached, light is scattered. As a result, the propagation path is changed so that light having an angle of incidence smaller than the total reflection critical angle passes through the exit surface and is uniformly upward.

On the other hand, the protective window 400 formed on the side of the opening 130 of the housing 100 generates a scratch upon contact with any external body, resulting in poor scattering of transmitted light.

Thus, the housing 100 is preferably formed to detach the cover 500 to protect the protective window (400).

That is, the cover 500 serves to protect the protective window 400 by covering the front side of the housing 100.

Here, the cover 500 may be applied in various shapes and various materials.

In addition, the device circuit board 210, the LED device 220, the light guide plate 230, and the protective window 400 may be firmly fixed to the inside of the housing 100.

Thus, the housing 100 forms the partition wall 140 to face each other inside the opening 130 side.

The partition wall 140 serves to seat and fix the device circuit board 210, the LED device 220, and the light guide plate 230 therebetween.

In particular, it is preferable that the partition wall 140 located at the front side of the pair of partition walls 140 facing each other is opened so that light is radiated toward the opening 130.

Of course, the partition wall 140 is made of a variety of shapes, it is preferable to be integrally formed in the housing 100.

At this time, the partition wall 140 is divided into upper and lower preferably formed integrally with the upper housing 110 and the housing corresponding to each.

In addition, one side of the protective window 400 is supported by the partition wall 140 located at the front side. At this time, the circumferential surface of the protective window 400 is fixed in close contact with the inner surface of the housing 100.

Here, the protective window 400 is preferably mounted so as not to be separated out through the opening 130 of the housing 100.

Thus, the housing 100 forms a support member 150 which is bent and extended at the edge of the opening 130.

The support member 150 serves to firmly secure the protective window 400 in contact with the other edge of the protective window 400.

Of course, the support member 150 is divided into upper and lower preferably formed integrally in the upper housing 110 and the lower housing 120 respectively corresponding.
