A flowchart for illustrating an example of a process for forming the laminated structure of Fig. 9 is shown.

Referring to FIG. 9, a first transparent window, a second transparent window, and a third transparent window include a polycarbonate base substrate 90 and Te deposited on the upper surface of the polycarbonate base substrate 90 to have a thickness of 10 A to 50 A A second peeling layer 94 formed by depositing InTiOx on the first peeling layer 92 to a thickness of 20 A to 30 A and a second peeling layer 94 formed to a thickness of 20 A to 30 A, And a silica layer 96 formed by depositing SiOx on the upper surface of the release layer 94 to have a thickness of 100 ANGSTROM to 300 ANGSTROM.

An example of a process for forming a laminate structure on such a transparent window is shown in Fig. 10, in which a polycarbonate substrate is prepared (S100), a prepared polycarbonate substrate is given a vacuum environment in a large chamber, A laminated structure can be formed by a deposition process as described below.

First, Te (tellurium) is deposited on the substrate to form a first peeling layer 92. Te is an optical recording material which has been used for a long time in an optical recording medium for optical recording. In the present invention, it is used for a long period of time to be easily peeled by natural light from the outside and LED light emitted from the inside, Is the first core content of.

Te is formed to a thickness of 10 ANGSTROM to 50 ANGSTROM to provide a first peeling layer 92. [ Next, a second peeling layer 94 is formed on the top surface of the first peeling layer 92 by forming InTiOx to a thickness of 20 Å to 30 Å. InTiOx is conventionally used as a conductive film material. In the present invention, the second peeling layer 94 is formed on the first peeling layer 92 made of Te as the second key content of the present invention. In the present invention, InTiOx enables the heat generated by irradiation of Te to be transmitted smoothly to the surroundings by the LED light. SiOx is deposited on the second release layer 94 to form a silica layer 96 having a thickness of 100 Å to 300 Å.

In the first transparent window, the second transparent window, and the third transparent window constructed as described above, contamination due to dust or pests due to use for a long period of time is accumulated, and the cleaning is performed once a year by the high pressure sprayer periodically performed.

In this cleaning process, the first transparent window, the second transparent window, and the third transparent window of the LED-based modular emotional illumination apparatus according to the present invention are provided with a peeling layer, and a transparent silica layer is formed on the surface of the peeling layer The following effects can be achieved.

The first peeling layer 92 formed of Te having a thickness of 10 Å to 50 Å is irradiated with natural light from the outside and LED light emitted from the inside for a long period of time and is modulated by the irradiated light and prepared . Here, the periphery thereof can be less peeled off compared to the portion where the LED is intensively irradiated. Therefore, according to the present invention, the second peeling layer 94 made of InTiOx is formed on the first peeling layer 92, and the heat generated by irradiation of the Te with the LED light is more smoothly To be delivered. SiOx is deposited on the second release layer 94 to form a silica layer 96 having a thickness of 100 Å to 300 Å. Further, the outermost transparent silica layer is less susceptible to adsorption of pests and contaminants than a polycarbonate material.

If the thickness of Te is less than 10 Å, the effect of peeling becomes insufficient. If the thickness of Te is more than 50 Å, transparency of the transparent window is lowered. Therefore, it is preferable that the thickness is 10 Å to 50 Å.

When the thickness of InTiOx is less than 20 Å, the thermal conduction effect is insufficient. When the thickness of InTiOx is more than 30 Å, the transparency rapidly decreases. Therefore, it is preferable that the thickness of InTiOx is 20 to 30 Å.

If the silica layer 96 is formed to be less than 100 angstroms, the externally exposed surface is easily broken by external scratches. If the silica layer 96 is formed to have a thickness of more than 300 angstroms, But it is preferable to form the layer with a thickness of 100 ANGSTROM to 300 ANGSTROM since it causes denaturation by temperature rise of the lower layer in the lamination process.

As described above, the LED-based modular emotional illumination device according to the present invention including the transparent window having the peeling layer as described above can clean the surface layer by washing with the high-pressure sprinkler which is performed once a year to two years, . ≪ / RTI > In addition, if foreign substances are accumulated on the surface again afterwards, the polycarbonate substrate can be replaced with a new polycarbonate substrate because it is denatured if used for about five years, and regularly replaced every five years.

In addition, the modular emotional illumination device based on the LED according to the present invention as described above is formed on a circuit board, in which a LED and a lens emit light downward, and a transparent cylindrical shape A first inclined portion 120 extending downward and inclined, and a second inclined portion 120 inclined downward at an end portion of the first inclined portion 120. The first LED lighting device module 10 includes a first transparent window, A second LED lighting device module 12 having a second inclined portion 122 formed on the first inclined portion and an LED and a lens inserted and formed in the second inclined portion, and a cut- And a third LED lighting device module (14) arranged in the interior of the incision window, the LED lighting device module being arranged vertically along an incision and emitting light toward the ground, wherein the LED lighting device module 10 or the second LED lighting device module 12 or the third LED lighting device module 14 may be vertically and selectively assembled to be installed in various designs depending on the installed location or environment.

The above examples and comparative examples were evaluated. In the evaluation method, the contaminants were applied to the surface and dried, and then the LED light source was irradiated for 72 hours at a strength of about 10 times as high as the standard, and the peeling layer was peeled off by spraying water at a temperature of 20 ° C at a pressure of 10 psi.

Indicates a state in which a peel layer is fine but is visually recognized clearly;?

There is a small amount of residual release material. Third Embodiment ○ The peeling state is very good
Initial opacity is increased slightly. Comparative Example 1 △ There is some residual release material Comparative Example 2 △ The peeled state is very good, but the opacity rapidly increases and the brightness decreases.

On the polycarbonate substrate, Te 40 Å , InTiOx 20 ANGSTROM, and SiOx 200 ANGSTROM in the second embodiment, the peeling state and the initial opacity are good. However, it is expected that the heat conduction effect will be lowered due to the reduction of the thickness of InTiOx. In addition, in the third embodiment in which Te of 50 Angstroms, InTiOx of 25 Angstroms and SiOx of 200 Angstroms were laminated on the polycarbonate substrate, the peeling state was very good, but the initial opacity was slightly increased due to the increase of Te thickness.

In the second comparative example in which Te 70 Å, InTiOx 25 Å and SiOx 200 Å were stacked The exfoliation state was very good, but initial opacity increased rapidly and brightness decreased. In the third comparative example in which Te 40 Å, InTiO x 25 Å and SiO x 400 Å were stacked, the Te layer was denatured during the deposition of SiO x, and the opacity was increased.

Therefore, it is preferable that the thickness for forming the first peeling layer 92 by depositing Te is 10 A to 50 A, and the second peeling layer 94 is formed by depositing InTiO x on the first peeling layer 92 The thickness is preferably 20 A to 30 A thick.
