Referring to Figures 1A and 1B, an exploded perspective view of a cosmetic case 100 with illumination according to various embodiments of the present invention is shown.

1A and 1B, a cosmetic case 100 according to an embodiment of the present invention may include a lower case 110, an upper case 120, and an illumination unit 130.

The lower case 110 is, for example, though not limited to, a substantially cylindrical shape, and has a space for accommodating the contents such as eye shadow, twin cake, and palette-shaped lipstick on the upper side. Since the lower case 110 is the same as or similar to the conventional structure, a further description thereof will be omitted.

The upper case 120 may have a substantially cylindrical shape, for example, but not limited to, one side opened and the other side closed, and a predetermined region may be coupled to the lower case 110 with a hinge 123. Accordingly, the upper case 120 can close the lower case 110 or keep the upper case 120 open from the lower case 110. The upper case 120 is provided with a mirror 140 on the side facing the lower case 110 so that when the upper case 120 is opened, the user can make up while viewing the mirror 140 . The upper case 120 may be formed of, for example, but not limited to, ordinary plastic or metal.

The illumination portion 130 is formed along the entire circumference of the mirror 140, for example, but not limited thereto, so that light can be emitted from the periphery of the mirror 140 toward the user. For example, if the mirror 140 is circular, the illumination unit 130 is also formed in the form of a circular ring outside the mirror 140. If the mirror 140 is rectangular, the illumination unit 130 is also rectangular And may be formed in a ring shape.

Specifically, the lighting unit 130 includes a battery 131, a battery loader 132, a printed circuit board 133, a reflector 134, a light guide plate 135, a light diffusion plate 136, and a cover 137 .

The battery 131 may include, for example, but not limited to, a non-rechargeable primary battery or a rechargeable secondary battery. The battery 131 may be, for example, but not limited to, a circular battery, a prismatic battery, or a pouch-shaped battery.

The battery loader 132 is hinged to a predetermined region of the upper case 120 to load the battery 131 into the upper case 120 or unload the battery 131 from the upper case 120 to the outside . The battery loader 132 may include a battery mounting groove (not shown) formed to stably mount the battery 131.

The printed circuit board 133 may include a plurality of LEDs (Light Emitting Diodes) (not shown) mounted on one side thereof, and may include a plurality of printed circuit patterns formed on the surface to connect the LED 131 to the battery 131 have. In addition, an open sensor (not shown) for detecting the opening (opening) of the lower case 110 and / or an illuminance sensor (not shown) for detecting the ambient illuminance may be electrically connected to the printed circuit board 133 have. This will be described below again (see FIG. 4).

The reflector 134 may be positioned along a portion of the periphery of the mirror 140 (e.g., approximately 60% to 90% of the overall circumference) as one side of the printed circuit board 133. The reflector 134 may be formed in a circular ring shape or a horseshoe shape in which one side is open, but not limited thereto. The reflector 134 reflects the light transmitted through the light guide plate 135 to the front side (user side), and may be formed of a metal (for example, aluminum, silver, or the like) .

The light guide plate 135 may be positioned along a part of the periphery of the mirror 140 (for example, approximately 60% to 90% of the entire periphery) as the front surface of the reflector 134. [ The light guide plate 135 may be formed in a circular ring shape or a horseshoe shape in which one side is opened, for example, but not limited thereto. The light guide plate 135 serves to transmit light from the LEDs of the printed circuit board 133 incident from one side or both sides along the longitudinal direction thereof.

That is, the LEDs mounted on the printed circuit board 133 directly or indirectly come into contact with one side or both sides of the light guide plate 135. The light guide plate 135 is formed so that the point light sources of the LEDs Thereby allowing light to be transmitted.

For example, the light guide plate 135 may be formed of transparent acrylic (PMMA), and a pattern having a predetermined area and shape may be printed on the back surface (the surface facing the reflector 134) of the light guide plate 135 . ≪ / RTI > Accordingly, after the light emitted from the LEDs on one side and / or both sides flows into the inside of the light guide plate 135, light is uniformly distributed over the front surface (the surface facing the light diffusion plate 136) . In other words, due to the scattering pattern formed on the rear surface of the light guide plate 135, the light impinging on the light guide plate 135 is irregularly emitted to the front surface.

The light diffusion plate 136 may be positioned along the entire circumference of the mirror 140 as the front face of the light guide plate 135. [ The light diffusing plate 136 may be formed in a closed circular ring shape, for example, but not limited thereto. The light diffusion plate 136 diffuses the light received from the light guide plate 135 to emit light toward the user in the form of a surface light source. That is, the light diffusion plate 136 diffuses the light received from the light guide plate 135 more uniformly so that the light is actually directed to the user. In other words, the light diffusing plate 136 is formed in a ring shape along its entire periphery with respect to the mirror, thereby providing uniform and bright light to a region (for example, a face) reflected by the mirror, Make it easy to make up. Here, when the light diffusing plate 136 or the illumination is formed or positioned only on one side of the mirror, there is a problem that some areas of the area reflected by the mirror are bright and some of the areas are dark, making makeup inconvenient.

The light diffusing plate 136 may be formed of, for example, but not limited to, acrylic (PMMA) or polycarbonate (PC), and a plurality of diffusion beads may be distributed therein. A plurality of embossings may be formed on the surface. Accordingly, the light transmitted through the light guide plate 135 is refracted and diffused inside the light diffuser plate 136, and the light that has met with the diffusion bead inside the light diffuser plate 136 repeats reflection and dispersion again In this process, the entire front surface has a uniform uniform brightness. Further, the brightness and illuminance of light can be further improved by embossing formed on the front surface.

As another example, the light diffusing plate 136 may include a seating surface 136a, an inner surface 136b, and a light emitting surface 136c. The seating surface 136a includes a substantially circular opening formed on the inner side, and is formed to have a predetermined thickness on the outer side thereof. The rear surface (i.e., rear surface) of the mirror 140 is seated on the seating surface 136a. In addition, the inner surface 136b extends in the vertical direction from the seating surface 136a, and the peripheral surface of the mirror 140 is in direct contact / close contact. That is, the inner diameter of the inner surface 136b of the optical diffusing plate 136 may be equal to or similar to the outer diameter of the mirror 140. Since the thickness of the inner surface 136b is equal to the thickness of the mirror 140, the light-emitting surface 136c and the front surface of the mirror 140 can be coplanar.

The light emitting surface 136c extends outward in the horizontal direction from the inner side surface 136b by a certain distance or width and emits light. This light emitting surface 136c is formed substantially along the entire circumference of the mirror 140 so that circular ring shaped illumination is provided outside the circular mirror 140. [

The cover 137 is formed in an arc shape, which is coupled onto the printed circuit board 133 so that the printed circuit board 133 is not released to the outside of the upper case 120. The cover 137 does not protrude beyond the thickness of the light guide plate 135, so that the light diffusion plate 136 is not interfered with by the cover 137. A recess 136d corresponding to the cover 137 may be formed on the rear surface of the optical diffusing plate 136 so as to minimize the interference with the cover 137. In this case, 130 may be thin.

In this manner, various embodiments of the present invention provide a cosmetic case 100 having light for makeup even at night or in the dark. That is, in various embodiments of the present invention, the illumination unit 130 is formed in a ring shape along the entire circumference of the mirror 140, thereby providing a bright light to the user, Lt; / RTI > In addition, various embodiments of the present invention provide a cosmetic case 100 in which illumination is turned on only when the upper case 120 is opened in a dark state by the illuminance sensor, so that the life of the battery 131 can be maintained for a long time.

Referring to FIGS. 2A, 2B, 2C, 2D, 2E, 2F and 2G, the cosmetic case 100 having illumination according to various embodiments of the present invention includes an upper case 120, A state in which the substrate 133 is coupled, a state in which the battery loader 132 is coupled, a state in which the reflector 134 is coupled, a state in which the light guide plate 135 is coupled, a state in which the light diffusion plate 136 is coupled, 140 are coupled to each other.

As shown in FIG. 2A, the upper case 120 may have a substantially cylindrical shape with one side opened and the other side sealed. That is, the upper case 120 has a substantially cylindrical case upper wall 121, a cylindrical case side wall 122 extending a certain length from the periphery of the case upper wall 121, and a side wall 122 formed on one side of the case side wall 122 And a hinge 123 rotatably coupled to the lower case 110. In addition, the upper case 120 may further include a coupling protrusion 124 formed on the opposite side of the case hinge 123 so as to be coupled to / detached from the lower case 110.

The upper case 120 may further include an opening circular groove shaped seating groove 125 formed to have a predetermined depth and width so that the reflector 134 and the light guide plate 135 are sequentially seated on the upper wall 121 of the case The battery loader 132 and the printed circuit board 133 are seated between the opposite end portions of the seating groove 125. [ Here, the space 126 may be formed in a region corresponding to the hinge 123.

The seating groove 125 is formed close to the case side wall 122 and the space portion 126 can be connected to the case side wall 122. The space portion 126 includes a battery mounting surface 126a on which the battery 131 and the battery loader 132 are seated and a battery mounting surface 126b on which the printed circuit board 133 is mounted and which is wider than the battery mounting surface 126a, (126b).

As shown in FIG. 2B, the printed circuit board 133 may be coupled to the space 126 described above. The planar shape of the printed circuit board 133 is the same as the shape of the space 126 described above so that the printed circuit board 133 does not move after being coupled to the space 126. [ In addition, although not shown in the drawings, the LEDs may be mounted on both ends of the printed circuit board 133 corresponding to the seating recesses 125. [ The cutout area 133a may be formed so that the battery loader 132 can be engaged / disengaged from the area where the battery loader 132 is located among the printed circuit boards 133. In addition, the printed circuit board 133 is covered with the arc-shaped or bow-shaped cover 137, so that the printed circuit board 133 is not released to the outside of the upper case 120. That is, the cover 137 may be fitted in the gap between the end of the hinge 123 and the printed circuit board 133.

The battery loader 132 may be coupled to the cutout area 133a of the printed circuit board 133 as shown in FIG. The battery loader 132 is hinged to one side of the upper case 120 so that the battery loader 132 can rotate around the hinge and be coupled to or separated from the printed circuit board 133 described above.

2 (d), an open loop or horseshoe shaped reflector 134 may be coupled to the seating groove 125 of the upper case 120 described above. That is, a ring-shaped reflector 134, which is not a complete circular ring, but an open side, can be coupled to the seating groove 125 of the upper case 120. At this time, the reflecting surface faces the front side (i.e., toward the lower case 110).

2E, an open loop or horseshoe shaped light guide plate 135 may be coupled to the seating groove 125 of the upper case 120 described above. That is, the light guide plate 135, which is not a complete circular ring, but is open at one side, can be coupled to the seating groove 125 of the upper case 120. At this time, since the reflector 134 is already attached to the seating groove 125, the light guide plate 135 is seated on the reflector 134.

A circular annular light diffusing plate 136 may be coupled onto the seating groove 125 and the cover 137 of the upper case 120 described above. That is, the optical diffusing plate 136 of the complete circular ring shape can be coupled to the seating groove 125 of the upper case 120. At this time, since the light guide plate 135 is already attached to the seating groove 125, the light diffusion plate 136 is seated on the light guide plate 135. In addition, as described above, the optical diffusing plate 136 may have an opening formed at the center, and a seating surface 136a, an inner surface 136b, and a light emitting surface 136c may be formed on the outer side. Here, the seating surface 136a and the inner surface 136b are not formed at positions overlapping the printed circuit board 133 (that is, by forming the groove 136d (see FIGS. 3A and 3B)), So that the seating surface 136a and the inner surface 136b do not interfere with the printed circuit board 133. [ That is, the width of the printed circuit board 133 and the width of the groove 136d may be the same or similar.

The light emitting surface 136c of the light diffusing plate 136 may be formed as a complete circular ring along the whole of the case side wall 122 of the upper case 120. [

As shown in FIG. 2G, the mirror 140 can be in a circular shape, which can be coupled to the seating surface 136a and the inner surface 136b of the light diffusing plate 136. As shown in FIG. Therefore, the mirror 140 is not separated from the light diffusing plate 136. In addition, the light emitting surface 136c of the optical diffusing plate 136 can be coupled in a circular ring shape along the entire circumference of the circular mirror 140. [

Accordingly, the illumination unit 130, that is, the light diffusion plate 136 is formed to surround the entire circumference of the mirror 140, thereby providing light to the user in a substantially circular ring shape. Accordingly, light is uniformly distributed over the entire area of the user's face, which is reflected by the mirror 140, so that it is possible to easily make up or repair makeup even at night or in the dark. Particularly, in the present invention, shadows or dark areas are not generated in the area reflected by the mirror 140. [

Referring to FIGS. 3A and 3B, an exploded perspective view illustrating a state in which the battery 131 is coupled to the battery loader 132 among the cosmetic case 100 having illumination according to various embodiments of the present invention is shown.

3A and 3B, the upper case 120 may further include an opening 127 formed in the side portion to enable loading and unloading of the battery 131 by the battery loader 132 . The opening hole 127 has a substantially rectangular shape, through which the battery loader 132 and the battery 131 can be drawn in or drawn out.

In particular, the opening hole 127 is formed at a portion corresponding to the hinge, so that it is not visible to the user in a general use environment. However, when the battery 131 needs to be replaced, the battery 131 can be easily replaced by pulling the battery loader 132 out.

Referring to Figure 4, a block diagram of an illumination circuit is shown in a cosmetic case 100 having illumination according to various embodiments of the present invention.

4, the cosmetic case 100 according to the embodiment of the present invention may further include an opening detection sensor 151, an illuminance sensor 152, and a switch circuit 153. The switch circuit 153 serves to supply or cut off the power of the battery 131 to the LED 144 of the printed circuit board.

For example, when the illuminance sensor 152 detects that the upper case 120 is opened by the opening detection sensor 151, the switch circuit 153 turns off the power of the battery 131 to the printed circuit board The LED 144 of FIG. Therefore, when the illuminance is equal to or greater than the reference value, even if the user opens the upper case 120, the illuminating unit 130, that is, the LED 144 is not turned on.

As another example, when the upper case 120 is opened by the opening detection sensor 151 and the illuminance is lower than the reference value by the illuminance sensor 152, the switch circuit 153 supplies the power of the battery 131 to the printing circuit To the LED 144 of the substrate. Therefore, when the user opens the upper case 120 in a state where the illuminance is lower than the reference value, the illumination unit 130, that is, the LED 144 is turned on.

In the cosmetic case 100 according to the embodiment of the present invention, the illuminating unit 130 does not operate at a predetermined illuminance value, and the illuminating unit 130 operates only below a predetermined illuminance value, It is possible to increase the use time of the apparatus.

Here, the reference value can be adjusted by a user by a setting unit or the like to be described below. For example, when the user wishes to make the lighting unit 130, that is, the LED 144 turned on in a brighter environment such as a night, as well as in a bright state such as the day, .

On the other hand, the open detection sensor 151 may be a normally open type reed switch, for example, but not limited thereto. The open-close sensor 151 is a switch that cuts off the current when the magnet is near and flows the current when it is away from the magnet. For example, a magnetic substance such as neodymium magnet may be installed on the lower case 110, and an open sensor such as a normally open reed switch may be installed on the upper case 120.

In this way, when the upper case 120 is closed in the lower case 110, the opening sensor is brought close to the magnetic body of the lower case to block the current, so that the LED of the illumination unit does not operate. However, when the upper case 120 is opened from the lower case 110, the opening sensor is moved away from the magnetic body of the lower case to allow the LED of the illumination unit to operate. This configuration and operation can be applied to all embodiments of the present invention. Accordingly, when the upper case is closed in the lower case, the LED of the illumination unit does not operate even if the touch sensor is touched. However, when the upper case is opened from the lower case, do.

5 to 8, the cosmetic case according to various embodiments of the present invention may also be provided with an illumination unit 230 in the upper case 220. Here, the upper case 220 may further include an inner case 210, which is additionally provided on the inner side so that the illumination unit 230 can be more stably mounted / coupled.

The inner case 210 may include a first region 211, a second region 212, and a third region 213. The first area 211 is formed along the approximate edge so that the reflector 234, the light guide plate 235, and the light diffusion plate 236 can be seated, which can have a relatively thin first thickness. The second region 212 is mounted on both sides of the printed circuit board 233 and may have a second thickness that is thicker than the first thickness. The control chip 253, the passive element, the battery, and the like) can be positioned. The third region 213 may be formed on the inner side from the first and second regions 211 and 212 and may have a third thickness so that the mirror 240 is seated. The third thickness may be thicker than the second thickness. That is, the third thickness may be thicker than the second thickness, and the second thickness may be thicker than the first thickness.

The reflector 234, the light guide plate 235, and the light diffusion plate 236 of the illumination unit 230 in the first area 211 around one side of the inner case 210 can be stably The printed circuit board 233 is stably positioned / coupled to the second area 212 around the other side of the inner case 210 and the third area 213 And the mirror 240 can be stably positioned on the printed circuit board 233.

In addition, at least one groove 213a may be formed in the third region 213 inwardly from the first region 211. Furthermore, at least one protrusion 234a may be further formed in the inward direction at the same position of the reflector 234, the light guide plate 235, and the light diffusion plate 236. [ Moreover, the plurality of projections 234a can be coupled to the groove 213a.

Therefore, the reflector 234, the light guide plate 235, and the light diffusion plate 236 do not rotate clockwise or counterclockwise on the inner case 210. Accordingly, even if the cosmetic case receives various physical / mechanical shocks from the outside, the illumination part 230 is stably coupled to the inner case 210 and the upper case 220, so that the quality of the illumination part 230 is deteriorated, (230) will not fail.

In addition, the printed circuit board 233 is formed in a substantially fan shape, and LEDs 254 can be mounted on both sides of the fan printed circuit board 233, respectively. Here, the LEDs 254 are not mounted in a vertical direction from a wide surface of the printed circuit board 233, but may be mounted in a substantially horizontal direction on a wide surface of the printed circuit board 233. [ As described above, the light guide plate 235 is a donut shape in which a portion of the light guide plate 235 is cut off. The light guide plate 235 has both side ends. Both side ends of the light guide plate 235 are bonded to both ends of the printed circuit board 233. At this time, the both side ends of the light guide plate 235 and the opposite side ends of the printed circuit board 233 are spaced apart from each other, and the LEDs 254 are positioned / interposed therebetween. Accordingly, both ends of the light guide plate 235 can easily receive light from the LEDs 254, respectively.

Accordingly, the light guide plate 235 receives the light of the LED 254 from both ends and guides light in the longitudinal direction thereof. Accordingly, light in the normal direction is emitted from the entire area of the light guide plate 235, and light in the normal direction is uniformly transmitted to the light diffusion plate 236, so that the light diffusion plate 236 also uniformly diffuses the light do.

Reference numeral 233a denotes an incision area formed in the printed circuit board 233, which serves to allow the battery loader 232 to be accommodated without interference. In the drawing, reference numeral 233b denotes a battery coupling portion 233b for receiving the battery 231 and electrically connecting the battery 231 to the printed circuit board 233.

The illumination unit 230 according to various embodiments of the present invention may further include a touch plate 221 and a conductive wiring 237. [

The touch panel 221 may be formed to penetrate the substantially central portion of the upper case 220 so that the user opens the upper case 220 from the lower case and then the touch panel 221 Can be easily touched with the index finger. The touch plate 221 may be formed of, for example, but not limited to, a conductive metal, a conductive plastic, a conductive ceramic, or the like. The touch plate 221 may be formed by the thickness of the upper case 220 to replace the central region of the upper case 220 or may be thinly coated or plated on the outer surface of the upper case 220.

Such a touch plate or the touch sensor 221 may be formed by a resistive film method or a corrected capacitance method. In the resistive membrane type, a touch is sensed by the resistance contact between the electrode and the electrode. In the electrostatic capacitance type, a certain current is passed between the electrodes, and the human body senses the touch of the mark.

Further, the conductive wiring 237 can electrically connect the printed circuit board 233 and the touch plate 221. That is, a touch region 238 may be formed on the printed circuit board 233 in addition to the control chip 253, the passive element and the LED 254. One end of the conductive wiring 237 may be connected to the touch region 238 And can be electrically connected. For example, although not limited thereto, one end of the conductive wiring 237 may be soldered to the touch region 238. In addition, the other end of the conductive wiring 237 can be electrically connected to the touch plate 221. For example, although not limited thereto, the other end of the conductive wiring 237 may be soldered to the touch plate 221.

In addition, the conductive wiring 237 may be made of, for example, a conductive wire, a conductive tape, a conductive film, or the like, although it is not limited thereto.

Thus, the cosmetic case according to various embodiments of the present invention may be configured such that the user touches the touch plate 221 provided in the upper case 220 a predetermined number of times and / or a predetermined number of times after opening the upper case 220 from the lower case. The LED 254 is turned on when the touch panel 221 is touched for a predetermined time and the LED 254 is turned off when the touch panel 221 is touched again for a predetermined number of times and / .

Figure 9 is a block diagram illustrating an illumination circuit among cosmetic cases with illumination according to various embodiments of the present invention.

9, the illumination circuit of the cosmetic case according to various embodiments of the present invention includes a switch circuit 253 that receives power from the battery 231, an open circuit that detects the open state of the upper case 220, A setting unit 255 for setting various operation modes by the switch circuit 253, a touch sensor 221 for detecting whether the user touches the touch panel, a LED 254 for providing light, . ≪ / RTI >

Here, the switch circuit 253 may be referred to as the control chip 253 described above, and the touch sensor 221 may be referred to as the touch plate 221 described above. The control chip 253 includes a counter 253a for counting the number of touches of the touch plate 221 and operating the LED 254 in a predetermined operation mode, a counter 253a for counting the touch time of the touch plate 221, 254 to operate in a predetermined operation mode. In addition, the sensing operation of the touch plate 221 is naturally detected after the upper case 220 is detected as being opened by the open sensor 251.

The control chip 253 may be mounted on the printed circuit board 233 and the setting unit 255 may be provided on the printed circuit board 233 as described above. The setting unit 255 may include, for example, but not limited to, a jumper cap (not shown) coupled to a jumper pin (not shown) provided on the printed circuit board 233. Accordingly, depending on the mutual engagement position of the jumper pin and the jumper cap, the control chip 253 can have various operation modes and can control the LED 254. The setting unit 255 may be set at a factory before shipment or may be set by a user who has received the product. In addition, the setting unit 255 may be separately provided in the lower case or the upper case by a touch input method.

Hereinafter, the first operation mode S1 to the fourth operation mode S4 of the control chip 253 according to the setting state of the setting unit 255 will be described.

10A to 10D are explanatory views showing four operation modes of an illumination circuit among cosmetic cases having illumination according to various embodiments of the present invention.

10A, the control chip 253 in the first operation mode S1 controls the LED 254 in three levels of brightness. That is, in the first operation mode S1, the control chip 253 changes the brightness of the LED 254 according to the number of touches of the touch plate 221 by the user.

For example, the control chip 253 may cause the LED 254 to emit light at the first brightness during the first touch of the touch plate 221 and the LED 254 during the second touch of the touch plate 221 The third brightness of the touch panel 221 causes the LED 254 to emit the third brightness and the fourth touch of the touch panel 221 turns the LED 254 off. Here, the second brightness is greater than the first brightness, and the third brightness is greater than the second brightness.

At this time, no operation is performed when the touch plate 221 is touched and held. Basically, the number of touches of the touch plate 221 can be judged by the counter 253a described above.

10B, in the second mode of operation S2, the control chip 253 sets and controls the brightness of the LEDs 254. That is, in the second operation mode S2, the control chip 253 sets and controls the brightness of the LED 254 according to the touch time and / or the number of touches of the touch plate 221 by the user.

For example, the user can hold the touch panel 221 while touching the touch panel 221 until the brightness of the LED 254 becomes the desired brightness. (1) Then, The LED 254 maintains the light emitting state with the brightness of that state. (2)

Then, when the user first touches the touch plate 221, the LED 254 fades up to the set brightness described above and emits light. In addition, if the user touches the touch panel 221 a second time, the LED 254 fades down from the set brightness described above and then turns off.

Basically, the touch hold time of the touch plate 221 can be judged by the timer 253b described above.

As shown in FIG. 10C, in the third mode of operation S3, the control chip 253 may cause the LEDs 254 to fade up and / or fade down. That is, in the third operation mode S3, the control chip 253 fades up or fades down the brightness of the LED 254 according to the number of touches of the touch plate 221.

By way of example, and not limitation, when the user first touches the touch plate 221, the LED 254 fades up and brightens from the off state of the LED 254 to the full brightness. Thereafter, when the user touches the touch plate 221 for the second time, the LED 254 fades down from the maximum brightness of the LED 254, and finally the LED 254 turns off. At this time, no effect is shown when the user touches and holds the touch panel.

10D, the control chip 253 may turn on / off the LED 254 in the fourth operation mode S4. That is, in the fourth operation mode S4, the control chip 253 turns on or off the LED 254 according to the number of touches of the touch plate 221

By way of example, and not by way of limitation, when the user first touches the touch plate 221, the LED 254 is simply turned on at a predetermined brightness. Further, when the user touches the touch plate 221 for the second time, the LED 254 is simply turned off. Here, when the user touches and holds the touch plate 221, the brightness of the LED 254 weakens as desired but does not turn off. In addition, when the user next touches the touch plate 221, the LED 254 may be turned off.

As described above, the various embodiments of the present invention include a first operation mode S1 for changing the brightness of the illumination according to the number of touches of the user, a second operation mode S1 for setting and controlling the brightness of the illumination according to the user's touch time, A third operation mode S3 for fading down or fading down the brightness of the illumination according to the number of touches of the user, a second operation mode S3 for turning on / off the illumination according to the number of touches of the user, , And a fourth operation mode (S4) in which the operation mode is changed.
