Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have.

Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen).

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

The mobile terminal according to the present invention may include a function of illuminating the surroundings. Such a mobile terminal may be termed a 'lighting device', a 'smart lighting device' or the like. Hereinafter, the term 'illumination device' will be described, but the present invention is not limited thereto, and can be applied to all similar mobile terminals.

The illumination device according to the present invention can be configured to illuminate the surroundings. Further, the illumination device can be made to provide various information to the user.

Hereinafter, the components of the lighting apparatus according to the present invention will be described. 2 is a block diagram showing the components of the lighting apparatus.

The lighting device 200 according to the present invention may include at least one of the components described in FIG. 2, the illumination device 200 includes a wireless communication unit 210, an input unit 220, an illumination unit 230, a sensing unit 240, a projection unit 260, a control unit 280, (290). In the following, the components of Fig. 2 will be mainly described, and the additional or supplementary description will be replaced with Fig.

The wireless communication unit 210 may include one or more modules that enable wireless communication between the lighting device 200 and the wireless communication system, between the lighting device 200 and the lighting device 200, or between the lighting device 200 and the external server. . ≪ / RTI > In addition, the wireless communication unit 210 may include one or more modules that connect the lighting device 200 to one or more networks. A concrete description of the wireless communication unit 210 is replaced with the contents described in FIG.

The input unit 220 may include a camera 221 for a video signal and a user input unit 223 for receiving information from a user. The image data collected by the camera 221 may be analyzed and processed by the user's control command.

The user input unit 223 may be implemented as a touch screen 251. The touch screen 251 may be configured to detect a touch applied to the touch screen 251 through a user's finger.

Furthermore, in the present invention, the touch screen 251 may be implemented as a flexible touch screen. Hereinafter, the flexible touch screen will be described in detail.

More specifically, the touch screen 251 according to an exemplary embodiment of the present invention may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the touch screen 251. This deformable touch screen 251 may be referred to as a " flexible touch screen ". Here, the flexible touch screen 251 may include both a general flexible touch screen and electronic paper (e-paper) and combinations thereof.

A typical flexible touch screen is a sturdy touch screen that is lightweight and does not break easily, while being made on a thin, flexible substrate that can be folded, bent, folded, twisted or curled like paper while maintaining the characteristics of a conventional flat touch screen.

In addition, the electronic paper is a touch screen technology applying general ink characteristics, and the point of using reflected light may be different from the conventional flat touch screen. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

In a state in which the flexible touch screen 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the touch screen area of the flexible touch screen 251 is flat. In the first state, the touch screen region may be curved in a state deformed by an external force (for example, a state having a finite radius of curvature, hereinafter referred to as a second state). The information displayed in the second state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

The flexible touch screen 251 may be placed in a bent state (e.g., a state in which the flexible touch screen 251 is bent up or down or left and right) instead of a flat state in the first state. In this case, when an external force is applied to the flexible touch screen 251, the flexible touch screen 251 may be transformed into a flat state (or a less curved state) or a more curved state.

On the other hand, when a touch is made to the flexible touch screen 251, the control unit 280 can perform control corresponding to the touch input. The flexible touch screen 251 may be configured to detect the touch input in the first state as well as the second state.

Meanwhile, the illumination device according to the present invention may be provided with a deformation sensing means for sensing deformation of the flexible touch screen 251. The deformation detecting means may be included in the sensing unit 240.

The deformation sensing means may be disposed at or around the flexible touch screen 251 to sense information related to the deformation of the flexible touch screen 251. Here, the information related to the deformation may be the direction in which the flexible touch screen 251 is deformed, the degree of deformation, the deformed position, the deformation time, and the acceleration at which the deformed flexible touch screen 251 is restored, In addition, the flexible touch screen 251 may be various information that can be detected due to bending of the flexible touch screen 251.

The control unit 280 may change the information displayed on the flexible touch screen 251 or change the information displayed on the flexible touch screen 251 based on information related to the deformation of the flexible touch screen 251 detected by the deformation sensing unit. It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the illumination device 200 according to the present modification may include a cap that receives the flexible touch screen 251. Gad may be configured to be deformable together with the flexible touch screen 251 by an external force in consideration of the characteristics of the flexible touch screen 251.

In addition, the battery (not shown) included in the lighting apparatus 200 may be configured to be deformable together with the flexible touch screen 251 by an external force in consideration of the characteristics of the flexible touch screen 251. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.

The state change of the flexible touch screen 251 is not limited to an external force. For example, when the flexible touch screen 251 has the first state, it may be transformed into the second state by the user's command.

The illumination unit 230 may include one or more light source elements to illuminate the space where the illumination device 200 is located. The light source device may be configured to emit light by receiving power from a power supply unit 290. For example, the light source device may be a light-emitting diode (LED) light source device. In this case, the light source device may be configured to emit light having various illuminations and colors.

The sensing unit 240 may sense information on the periphery of the illumination device 200 and generate corresponding sensing signals. The sensing unit 240 may include at least one sensor.

2, the sensing unit 240 may include at least one of a proximity sensor 241, a pressure sensor 243, and a distance sensor 244. As shown in FIG.

The proximity sensor 241 can detect an object located in an area in contact with or proximate to one side of the main body of the illumination device 200 by using infrared rays or the like. For example, the proximity sensor 241 may sense a user located in a nearby area of the lighting device 200.

The pressure sensor 243 can measure the pressure applied to the illumination device 200. [ Further, the control unit 280 may determine whether an object exists on the illumination device 200 based on whether the sensed value measured by the pressure sensor 243 is equal to or greater than a predetermined value.

The distance sensor 244 can measure the distance from the illumination device 200 to an object located in the periphery of the illumination device 200 using ultrasonic waves or light.

In addition, the sensing unit 240 may include a line-of-sight sensor capable of sensing a user's line of sight.

The projection unit 260 is formed to project image information to the outside. The projected image information is enlarged on the external screen. The screen refers to an object that blocks or reflects the progress of light to be projected, such as a screen for a beam projector, a wall or a bulletin board. However, the display of the projected image information is not limited to the method using the screen, and other methods may be used as long as the image information can be recognized by the user.

The control unit 280 may control the above-described components to operate various functions in the lighting apparatus 200. [ For example, the control unit 280 may control the projection unit 260 so that the generated image information is projected based on information received from the wireless communication unit 210.

In the foregoing, the components of the lighting device 200 according to the present invention have been described. Hereinafter, the structure of the lighting apparatus 200 according to the present invention will be described with reference to Figs. 3A and 3B and Figs. 4A to 4C. Fig.

3A is a conceptual diagram showing the structure of a lighting apparatus according to an embodiment of the present invention. FIG. 3B is a conceptual diagram illustrating the structure of a lighting apparatus according to another embodiment of the present invention.

4A to 4C are conceptual diagrams showing a structure of a lighting apparatus according to another embodiment of the present invention.

Referring to FIG. 3A, the lighting apparatus 200 according to the present invention may include an illumination unit 230, a projection unit 260, and a lamp shade 202 (hereinafter, referred to as a shade).

The illumination unit 230 and the projection unit 260 may be included in the main body 201 and may be integrally formed. In other words, a lighting unit 230 for emitting light is formed in a part of the main body 201, and a projection unit 260 for emitting image information can be formed in another part. For example, as shown in the figure, an illumination unit 230 may be formed on the upper portion of the main body 201, and a projection unit 260 may be formed on the lower portion.

The shoulder 202 may be configured to surround at least a portion of the body 201. For example, the shade 202 may be configured to surround the side surface of the main body 201 as shown.

According to the above structure, the main body 201 can be disposed on the internal space defined by the shade 202. Accordingly, at least a part of the light emitted from the illuminating unit 230 provided in the main body 201 can be transmitted to the outside through the shade 202.

In addition, the image information projected by the projection unit 260 can be enlarged and displayed on the shade 202. This will be discussed in more detail later with reference to Figs. 4A to 4C.

The main body 201 and the shoulder 202 can be mounted on the pillar 204 via the connecting portion 203. The pillars 204 may be formed so as to be erected from the ground. Accordingly, the lighting apparatus 200 according to the present invention can be realized in the form of a stand.

Referring to FIG. 3B, the illumination device 200 according to the present invention may be formed to be attachable to a wall or the like.

Referring to FIG. 3B, the main body 201 may include an illumination unit 230 and a projection unit 260, as described above. Further, the main body 201 may be formed to be mountable on the auxiliary body 205.

Adhesive portions (not shown) for attaching the auxiliary body 205 to a flat surface such as a wall may be provided on a surface of the auxiliary body 205 opposite to the surface on which the main body is mounted. The adhesive portion may be formed of at least one of a transparent adhesive or an adhesive film.

A first magnet may be provided at a portion of the auxiliary body 205 that contacts the main body 201 and a second magnet may be provided at a portion of the main body 201 in contact with the auxiliary body 205. Due to the attraction force formed between the first and second magnets, the main body 201 can be mounted on the auxiliary body 205.

Also, although not shown, at least one of the first and second magnets may be moved so that the main body 201 may be rotatable on the auxiliary body 205.

Up to now, a schematic structure of the illumination device 200 according to the present invention has been described. Hereinafter, with reference to Figs. 4A to 4C, a detailed structure of the illumination device 200 will be described.

4A to 4C, the illumination device 200 according to the present embodiment includes an illumination unit 230, a projection unit 260, and a shade 202.

The illumination unit 230 is configured to illuminate a space where the illumination device 200 is located. In the present embodiment, the illumination unit 230 may be disposed at a central portion of the inner space defined by the shade 202. The light output from the illumination unit 230 can be radiated in all directions without any directionality.

The projection unit 260 is configured to project image information in one of the spaces. In this embodiment, the one area may be formed on at least a part of the surface of the shade 202.

Specifically, a mirror 261 may be disposed on the projection path of the image information. The direction of the projection path of the image information can be switched by the mirror 261. [

For example, the image information projected from the projection unit 260 may be primarily upwardly reflected, reflected by the mirror 261, and then traveled toward the fresh surface. The image information emitted from the projection unit 260 is finally projected onto a part of the surface of the shade 202.

Meanwhile, the mirror 261 may be connected to the first and second hinge parts 262 and 263. Specifically, as the first hinge portion 262 is operated, the height at which the mirror 261 is positioned on the inner space of the shade can be changed. Also, as the second hinge part 263 is operated, the angle of the mirror 261 can be changed. As the angle of the mirror 261 is changed, the position of the surface 202a on which the image information is projected on the shade 202 can be changed.

On the other hand, the darker the portion 202a where the image information is projected, the greater the discrimination power of the image information. Therefore, a shielding film 231 may be disposed between the illuminating unit 230 and a portion of the shade 202 where the image information is projected. In other words, due to the curtain film 231, it is possible to minimize the influence of the light output from the illumination unit 230 on the image information.

Meanwhile, as shown, the image information projected from the projection unit 260 may include various living information. For example, the living information may include at least one of weather information, date information, and time information.

Further, in the present invention, the image information may be information related to an external device wirelessly connected to the illumination device 200, and will be described in more detail with reference to the drawings.

Hereinafter, the external device wirelessly connected to the illumination device 200 will be described based on the mobile terminal 100. [

5A and 5B are conceptual diagrams for explaining a method in which the illumination unit is controlled such that the property of light is changed based on the kind of event information about an event generated in the mobile terminal.

The illumination device 200 according to the present invention receives event information related to an event generated in the mobile terminal 100 from a predetermined mobile terminal 100. [

More specifically, the wireless communication unit 210 of the lighting device 200 is configured to receive event information related to the event when an event is generated in the predetermined mobile terminal 100.

Here, the event may be at least one of a message reception, a call signal reception, a missed call, an alarm, a schedule notification, an email reception, and reception of information through an application.

Further, when the event information is received, the control unit 280 may control the projection unit 260 to project image information related to the event information. The image information may include at least one of a phrase and an image indicating that the event has occurred.

For example, referring to (a) and (b) of FIG. 5, when an event related to a missed call is generated in the mobile terminal 100, the wireless communication unit 210 receives event information related to the missed call . Further, the projection unit 260 projects image information corresponding to event information related to the missed call. For example, the image information may include information on the sender information of a missed call, the number of events generated in association with a missed call, and the like.

Referring to FIGS. 5A and 5B, when an alarm event occurs in the mobile terminal 100, the wireless communication unit 210 receives the alarm event information. Further, the projection unit 260 projects the image information corresponding to the alarm event information. For example, the image information may include time information for which an alarm is set.

Meanwhile, the control unit 280 may display the image information related to the event information, and may control the illumination unit 230 to turn on the illumination.

For example, when the event information is received, the control unit may control the illumination unit 230 so that the power of the illumination unit 230 is turned on when the illumination unit 230 is powered off .

Further, the controller may control the illumination unit 230 to change the property of light output from the illumination unit 230 based on the type of the event corresponding to the received event information.

Here, the attribute of the light may be at least one of a blinking period, an intensity, and a wavelength of light. Here, the intensity and wavelength of light may be factors that determine light intensity and color, respectively.

More specifically, when the first event information is received, the control unit 280 may control the illumination unit 230 such that light emitted from the illumination unit 230 has a first attribute corresponding to the first event information . The control unit 280 may control the illumination unit 230 so that the light emitted from the illumination unit 230 has a second attribute corresponding to the second event information when the second event information is received.

Accordingly, the user can more immediately recognize the type of the event generated in the mobile terminal through the illumination of the space where the illumination device 200 is located.

5A, when the controller 280 receives event information related to a missed call, the control unit 280 controls the illumination unit 230 so that the light emitted from the illumination unit 230 is flickered at predetermined intervals. Can be controlled.

Specifically, if the illumination unit 230 is emitting light before the event information related to the missed call is received, the control unit 280 controls the intensity of the light being emitted and the wavelength of the emitted light to be maintained, The illumination unit 230 can be controlled so that the period becomes a predetermined period.

The user can immediately recognize that an event related to the missed call has been generated in the mobile terminal through the flickering of the light emitted from the illumination unit 230.

Referring to FIGS. 5A and 5B, when the controller 280 receives event information related to an alarm, the controller 280 controls the illumination unit 230 to output light at a predetermined intensity.

In detail, if the light is emitted from the illumination unit 230 before the event information related to the alarm is received, the controller 280 controls the intensity and wavelength of the light being emitted, The illumination unit 230 can be controlled to have intensity.

Up to now, it has been shown that the properties of light output from the illumination unit 230 vary based on the type of event corresponding to the received event information. On the other hand, even if the types of the events corresponding to the received event information are the same, the attributes of light output from the illumination unit 230 may vary based on the contents of the event. Hereinafter, this will be specifically discussed.

6A and 6B are conceptual diagrams illustrating a method in which the illumination unit 230 is controlled such that the properties of light are changed based on the contents of an event generated in the mobile terminal.

According to the present invention, when an event related to reception of a text message is generated in the mobile terminal 100, the wireless communication unit 210 receives event information related to the text message. Here, the event information related to the text message may include at least one of information on the content of the text message and sender information of the text message.

In the present invention, light having different attributes may be output based on keywords included in the contents of the text message.

More specifically, the control unit 280 related to the present invention can control the illumination unit 230 to output light having the first attribute when the keyword includes a keyword belonging to the first category . The control unit 280 may control the illumination unit 230 to output light having a second attribute when a keyword belonging to the second category is included in the content of the text message.

For example, referring to (a) and (b) of FIG. 6A, when a keyword (e.g., love) included in the content of the text message belongs to a first category (for example, , Light having a first attribute (e.g., yellow color with a warm feeling) may be output.

6A and 6B, when a keyword (for example, a father-in-law) included in the content of the text message belongs to a second category (for example, a category related to negation) Light having an attribute (for example, a violet color having a dark impression) may be output.

According to another embodiment, light having different attributes may be output based on the sender information of the text message.

More specifically, the control unit 280 related to the present invention can control the illumination unit 230 to output light having the first attribute when the sender of the text message belongs to the first category. The control unit 280 may control the illumination unit 230 to output light having the second attribute when the sender of the text message belongs to the second category.

For example, if the sender of the text message belongs to a first category (e.g., a category associated with positive), light with a first attribute (e.g., a yellow color with a warm feeling) may be output.

Alternatively, when the sender of the text message belongs to a second category (for example, a category related to negation), light having a second attribute (for example, a purple hue of dark impression) may be output.

Here, the category to which the sender of the text message belongs may be preset by the user.

Meanwhile, the lighting device 200 according to the present invention is formed so as to be able to sense the position of the user with respect to the lighting device. Further, the lighting apparatus 200 provides various functions by using the detected position of the user. This will be specifically described with reference to the drawings.

FIGS. 7A and 7B are conceptual diagrams for explaining a control method in which a position where image information is projected is controlled based on a detected user's position.

The illumination device 200 according to the present invention may include a sensing unit 240 capable of sensing a position of a user with respect to the shade 202.

Specifically, the sensing unit 240 may include at least one of a proximity sensor 241 and a distance sensor 244. The control unit 280 may determine at least one of the proximity sensor 241 and the distance sensor 244 to determine the position of the user with respect to the shade 202.

For example, a plurality of the proximity sensors 241 may be provided, and the proximity sensors 241 may be disposed around the shoulders 202 at predetermined intervals. At this time, each proximity sensor 241 may be configured to transmit a specific signal value to the control unit 280 when the distance between the user and the shoulder 202 becomes shorter than a predetermined interval.

The control unit 280 can determine the position of the user with respect to the umbrella 202 based on the proximity sensor that transmits the specific signal value among the plurality of proximity sensors. In other words, the control unit 280 may determine the position of the user with respect to the umbrella 202 based on a predetermined position of the proximity sensor that transmits the specific signal value among the plurality of proximity sensors.

The projection unit 260 may be rotatable. More specifically, the projection unit 260 may be rotated by a driving unit (not shown) connected to the projection unit 260.

For example, the driving unit includes a coil magnet, and can rotate the projection unit 260 using an electromagnetic force generated from the coil magnet. As another example, the driving unit may include a motor such that the projection unit 260 rotates.

7A and 7B, the controller 280 controls the driving unit 260 to rotate the projection unit 260 such that the image information 710 is projected on the surface of the shade corresponding to the sensed user's position, Can be controlled.

7A, the control unit 280 controls the projection unit 260 such that a majority of the image information 710 is projected onto a portion 202a of the umbrella corresponding to the detected position of the user.

7B, the control unit 280 controls the projection unit 260 to change a portion 202b of the image information 710 to which a majority of the image information 710 is projected, when the detected position of the user is changed .

The control unit 280 controls the driving unit 260 so that the portion of the image information 710 projected on the surface of the shade 202 is periodically changed by the rotation of the projection unit 260. [ Control.

In this case, the control unit 280 may control the driving unit such that the projection unit 260 reciprocally rotates within a predetermined rotation angle and period based on a user's request.

Further, when an object recognized as a wall is detected in the periphery of the illumination device 200, the controller 280 controls the projection unit 260 such that when the projection unit 260 is rotated, the image information is not projected toward the object It is possible to control the driving unit to rotate within a predetermined range.

Meanwhile, although the projection unit 260 has been described as being connected to the driving unit and rotated by the driving unit, the present invention is not limited thereto. That is, the main body 201, in which the projection unit 260 is built, may be formed to be rotatable along the longitudinal axis of the illumination device 200.

Meanwhile, the illumination device 200 according to the present invention may include a touch screen 251. In this case, the projection unit may be controlled such that the image information is projected on a part of the umbrella corresponding to the applied touch, based on the coordinates of the touch applied to the touch screen 251.

Meanwhile, the illumination device 200 according to the present invention can provide various interfaces for controlling the properties of light output from the illumination through the touch screen 251. Hereinafter, this will be described in more detail.

8A and 8B are conceptual diagrams for explaining a method of controlling the properties of light output from an illumination through a touch screen according to an embodiment of the present invention.

Referring to FIG. 8A, a touch screen 251 may be formed on at least a part of the shade 202. Here, the touch screen 251 may be attached to the inner surface of the shade 202. In addition, the touch screen 251 may be formed to detect a touch applied to the outer surface of the shade 202.

The control unit 280 may control the illumination unit 230 to change the property of light output from the illumination unit 230 when a predetermined touch is applied to the touch screen 251.

For example, the control unit 280 may control the illumination unit 230 to increase the intensity of light when a drag touch is applied along one direction (e.g., d1 direction) of the touch screen 251 . In addition, the controller 280 may control the illumination unit 230 to decrease the light intensity when a drag touch is applied along the direction opposite to the one direction (for example, d1 'direction).

Here, the amount of change in intensity of the emitted light may be proportional to the length of the trajectory of the drag touch applied to the touch screen 251.

In addition, the controller 280 may control the illumination unit 230 so that the color of the light becomes brighter when a drag touch is applied along one direction (for example, d2 direction) intersecting the one direction. In addition, the controller 280 may control the illumination unit 230 so that the color of the light becomes dark when the drag touch is applied along the direction opposite to the one direction (for example, d2 'direction).

Here, the lightness and darkness of the color of the output light may be proportional to the length of the trajectory of the drag touch applied to the touch screen 251.

8B, the controller 280 displays a plurality of image objects 810a, 810b, and 810c corresponding to different colors at different positions of the touch screen 251, when a user request to select a color of light is input, 810b, 810c, and 810d.

The control unit 280 may control the illumination unit 230 to output light of a color corresponding to the selected image object 810c when any one of the plurality of image objects 810c is selected.

Meanwhile, while the plurality of image objects 810a, 810b, 810c, and 810d are being output to the touch screen 251, the illumination unit 230 may be controlled to reduce the intensity of the light. As the intensity of light is reduced, the visibility of the plurality of image objects 810a, 810b, 810c, 810d output to the touch screen 251 can be increased.

Up to now, various interfaces have been provided for controlling the properties of light output from the illumination unit through the touch screen 251.

Meanwhile, the property of the light output from the illumination unit 230 may be controlled by the image signal inputted through the camera 221. [ This will be described in detail with reference to FIG. 8C.

8C is a conceptual diagram for explaining a method of controlling the property of light output from the illumination unit 230 through a gesture input by the camera 221 according to an embodiment of the present invention.

8C, when a user request to select the color of the light output from the illumination unit 230 is input, the controller 280 controls the gesture of the user input through the camera 221, Can be processed by a control command for controlling the color of the image.

For example, when the first gesture 820a is detected through the camera 221, the control unit 280 may control the illumination unit 230 to darken the color of the light. The control unit 280 may control the illumination unit 230 to increase the color of the light when the second gesture 820b is input through the camera 221. [

In the above description, the color of the light is controlled through the gesture of the user input through the camera. However, it is also possible that other attributes (for example, light intensity) other than the color of the light are controlled.

Meanwhile, the lighting apparatus 200 according to the present invention can receive broadcast signals and / or broadcast-related information from an external broadcast management server. This will be described more specifically with reference to the drawings.

9 is a conceptual diagram of a lighting apparatus to which an antenna according to an embodiment of the present invention is applied.
