BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus using a light emitting element including an LED (Light Emitting Diode), and more particularly, to a lighting apparatus which can be easily changed in projection direction regardless of an installation environment,

In recent years, attempts have been made to use a light emitting device including a LED as a lighting device as a new light source to replace a conventional incandescent lamp or a fluorescent lamp. LEDs and other light emitting devices using semiconductors are small and have low power consumption. It is also possible to provide an advantage that the luminescent color and the luminescent pattern can be easily controlled.

However, since the light is projected in a specific direction due to the characteristics of the light emitting device, it is difficult to realize various illumination environments. Of course, a plurality of light emitting devices can be used to vary the direction of light projection. However, since the direction of light projection is limited to specific directions, it is also difficult to realize various illumination environments.

The illumination device may be used to provide uniform light to a particular space, or it may be used to provide light to a particular location intensively. However, the purpose and function of the lighting apparatus can not be limited depending on the structure of the lighting apparatus or the installation environment.

For example, in the case of a lighting device installed on a ceiling of a room, only a direct lighting function of directly projecting light into the indoor space can be performed. Further, in the case of the portable lighting device, it is basically possible to perform only a direct lighting function of directly projecting light at a specific location.

Therefore, there is a need to provide an illumination device capable of meeting various demands of the user for lighting environment as well as energy saving.

In particular, the stand type illumination device is a lighting device widely used in a home or an office, and is characterized by being installed very close to a user. Therefore, it is highly desirable that the user should be able to easily adjust the projection direction and have a good appearance.

However, in a stand-type lighting apparatus using an incandescent lamp, a fluorescent lamp or a halogen lamp, a shield for collecting light in the projection direction is usually used. Such a shield increases the volume of the lighting device, and the bulky shield portion is located in the air, giving the impression that it is not visually stable. Of course, there is also a limit to the beauty of the appearance.

Further, in general, the stand type lighting apparatus is restricted in installation environment. Normally, it is located on a horizontal plane such as a desk or a table. Therefore, there is a problem that a space for installing a lighting device on a horizontal surface of a desk or a table is necessarily required.

Whether using a lighting device or not, there is a problem that lamps are always exposed, so that a lot of dust may accumulate and cleaning is not easy. Further, there arises a problem that it occupies the same space regardless of whether the lighting apparatus is used or not, making it inconvenient to use.

SUMMARY OF THE INVENTION The present invention is basically intended to solve the above-mentioned conventional problems.

And it is an object of the present invention to provide a lighting device which can be installed in various environments through the embodiments of the present invention. Specifically, it is intended to provide a lighting apparatus which can be installed on a horizontal plane or a vertical plane or anywhere.

It is an object of the present invention to provide a lighting apparatus which can minimize an occupied space when a lighting apparatus is not used and has a beautiful appearance.

It is an object of the present invention to provide a lighting device in which a user can change the direction of light projection in various forms.

It is an object of the present invention to provide a lighting device which can implement various lighting patterns and can be used as interior accessories as well as simple lighting.

And it is an object of the present invention to provide a lighting device capable of effectively protecting a light emitting portion or a light emitting surface through an embodiment of the present invention.

In order to achieve the above-mentioned object, an embodiment of the present invention is characterized by comprising: a base; A panel having a front surface and a back surface provided with a light emitting portion; A first rotary member provided at one end of the base; A second rotary member provided at the other end of the panel; And a connecting member connecting the first rotating member and the second rotating member to each other. The first rotating member may constitute the rotation center of the other end of the panel and the second rotating member may constitute the rotation center of the one end of the panel.

The base and the panel are provided to face each other and to be folded, wherein the first rotating member, the second rotating member and the connecting member can be positioned between the base and the panel.

The base and the panel are formed in the same shape and size, and the light emitting part can be folded so as to face the base. Therefore, occupation space can be minimized when the lighting apparatus is not used. Specifically, since the panel portion does not float in the air, the space utilization can be maximized.

The base may be fixed to a horizontal plane or a vertical plane. In addition, illumination can be provided in various directions regardless of the fixed environment. In particular, it is possible to provide illumination directly on a horizontal surface or on a surface regardless of the fixed environment.

The connecting member may be rotatable with respect to the longitudinal direction so as to vary the angle at which the front surface of the base and the front surface of the panel face each other.

The first rotating member and the second rotating member may protrude from the front surface of the panel and the base, respectively.

The first rotating member and the second rotating member may be formed in a cylindrical shape. Thus, it is possible to increase the area in contact with the panel or base and these rotating members.

The connecting member may be connected to the circumferential surfaces of the first rotating member and the second rotating member.

The base may be provided with an electric field portion to which external power is applied. The base and the panel may be electrically connected to each other through a wire provided inside the connection member. The electric wire through the electric field portion may lead to the panel through the first rotating member, the connecting member, and the second rotating member. Therefore, it is possible to prevent the electric wire from being exposed to the outside of the lighting apparatus.

The first rotating member and the second rotating member are preferably provided so as to rotate with respect to a longitudinal direction and a width direction of the base. Here, this rotation may be referred to as a left-right rotation and a back-and-forth rotation with respect to the first rotating member itself.

The first rotating member and the second rotating member may be rotatably disposed in a direction in which the base and the light emitting portion of the panel are folded while facing each other.

The first rotating member and the second rotating member may be rotatable in a direction in which the base and the light emitting portion of the panel are folded while facing each other or are offset from each other. Here, when they are displaced from each other, it means that the rotation posture of the panel changes in a state where the base is fixed. That is, the angle at which the panel is raised with respect to the base changes.

In order to achieve the above-mentioned object, an embodiment of the present invention is characterized by comprising: a base; A panel having a front surface and a back surface provided with a light emitting portion; And an illumination angle adjusting device provided to connect the base and the panel to each other and to allow the base and the panel to be spaced from each other from a state in which the base and the panel are folded with each other and to change the angle of the panel with respect to the base Can be provided.

The connecting member may be provided with a rotating joint to rotate in the longitudinal direction of the connecting member. Of course, any one of the rotating members may be provided with such a rotating joint.

Hereinafter, a lighting apparatus according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 1, an embodiment of the present invention relates to a lighting apparatus. Fig. 1 shows a folded state. That is, when the lighting apparatus is not used, it is possible to keep the lighting apparatus in a folded state.

Specifically, the illumination device 100 may include a base 120 and a panel 110. [ Here, the base 120 supports the panel 110. The panel 110 may include a light emitting portion or a light emitting surface to provide illumination.

The panel 110 may include a back surface 112 and a front surface 111. The back surface 112 is a portion where a light emitting portion or a light emitting surface is not formed, and a light emitting portion or a light emitting surface is formed on the front surface 111. Accordingly, the state shown in FIG. 1 is a state in which the front face 111 faces the base 120, and therefore, the state in which no illumination is used.

The base 120 may also include a front surface 122 and a rear surface 121. The back surface 121 may be a portion fixed to a horizontal surface of a desk or a table or fixed to a vertical surface. Therefore, it is possible to install the lighting device regardless of the installation environment. This is because it is possible to provide illumination in various directions regardless of the environment as described later.

Meanwhile, it is preferable that the base 120 and the panel 110 have the same shape and the same size. In other words, it is preferable to be substantially symmetrical. Therefore, in the folded state, the front surface and the rear surface of the illuminating device can be made substantially the same. This makes handling and storage very easy.

The front surface 122 of the base 120 faces the front surface 111 of the panel 110. That is, when the illuminating device 100 is folded, the front surface 122 of the base 120 may face the front surface of the panel 110. FIG. The front surface 111 of the panel 110 can be prevented from being exposed to the outside. Therefore, it is possible to effectively protect the front surface 111 of the panel 110 that provides illumination when the illumination device 100 is not used. As a result, dust or the like may accumulate on the front surface 111 of the panel 110 or effectively protect the front surface 111 of the panel 110 from external impact.

Fig. 2 shows an example in which the base 120 is provided on a vertical plane.

As shown in the figure, the illumination device according to an embodiment of the present invention includes a first rotating member 210 provided on a base 120 and a second rotating member 220 (see FIG. 3) provided on the panel 110, . ≪ / RTI > The illumination device according to an embodiment of the present invention may include a connection member 230 connecting the first and second rotation members. Here, the first rotating member, the second rotating member, and the connecting member 230 may be referred to as an illumination angle adjusting device 200 for the base. That is, the direction in which the front surface of the panel 110 faces, that is, the direction of illumination, can be easily controlled through the adjusting device 200 and various adjustments can be made.

Specifically, the state shown in FIG. 2 shows a case where the base 120 is installed on the vertical plane and the front surface 111 of the panel 110 is downward. Thus, light can be projected toward a desk, a table, or the ground. It is also possible to raise the position of the panel 110 in the state shown in FIG. Therefore, it is possible to adjust the height between the ground surface and the panel 110 in a state where the base 120 is fixed to the vertical surface. Also, unlike the illustrated, the front surface of the panel 110 may be upside.

On the other hand, when the illumination is provided and the illumination is completed in the state shown in Fig. 2, the panel 110 and the base 120 can be folded as shown in Fig.

3 shows an example in which the base 120 is provided on a horizontal plane. Specifically, the front surface of the panel 110 is set to face forward. And the front surface of the panel 110 may be oriented rearward, unlike the one shown in FIG. Of course, the front surface of the panel 110 may be directed downward or upward.

The direction of the front surface 111 of the panel 110 with respect to the base 120 can be changed in various ways in addition to the states shown in FIGS. This can be achieved through the first rotating member, the second rotating member, and the connecting member 230.

On the other hand, the base 120 is not necessarily installed on a horizontal plane or a vertical plane. For example, the base 120 can be stably fixed on an inclined surface. Of course, the fixing method can be implemented in a wide variety of ways. The technical idea of the present invention is irrelevant to this and the fixing method can be obviously modified for those skilled in the art. Therefore, detailed description is omitted.

According to the present embodiment, the direction in which the front surface 111 of the panel 110 faces can be adjusted in various ways irrespective of the shape or place of the portion where the base is fixed. A variety of such adjustments can also be implemented through the illumination angle adjuster 200. [ For example, an illumination angle adjusting device including a first rotating member, a second rotating member, and a connecting member 230. In particular, it is possible to move or adjust the panel 110 in various positions or directions relative to the base 120 through these arrangements.

Hereinafter, the first rotating member, the second rotating member, and the connecting member 230 will be described in detail with reference to FIGS. 3 to 8. FIG.

As shown in FIG. 3, the first rotating member 210 and the second rotating member 220 may be substantially identical to each other. Thus, the rotatable aspects can be the same. The first rotating member 210 may be provided at one end of the base 120 and the second rotating member 220 may be provided at the other end of the panel 110. The first rotary member 210 and the second rotary member 220 may be connected to each other through a connection member 230. Therefore, the first rotating member 210, the second rotating member, and the connecting member 230 may be referred to as an illumination angle adjusting device 200, and the illumination angle adjusting device may include such configurations .

The illumination angle adjusting device 200 is a device for adjusting a direction and a position of the front surface 111 of the panel 110, that is, a surface for providing illumination, such as a rotation position and a separation position, with respect to the base 120 . Therefore, the user can easily adjust the angle and position of the illumination provided through the illumination angle adjusting device 200.

The illumination angle adjusting device 200 may be a device for connecting the base 120 to the panel 110 and adjusting the position and posture of the panel 110 with respect to the base. That is, it is possible to easily change the position of the panel 110 with respect to the base 120 through the lighting angle adjusting device 200, change the height of the panel 110, and adjust the angle of rotation of the panel 110.

As shown in FIGS. 4 and 5, the first rotating member may be rotatable in two directions. FIG. 4 shows a rotation of the base 120 in the vertical direction, that is, the rotation about the thickness direction. FIG. 5 is a view illustrating a rotation of the base 120 about the width direction. However, it is not limited to the number of such rotatable directions.

As described above, the first rotating member is provided at one end of the base 120. The first rotary member 210 is connected to the other end of the panel 110 through a connection member 230. Accordingly, rotation by the first rotary member 210 means rotation of the connection member 230, and rotation of the connection member 230 means rotation of the other end of the panel 110. Accordingly, the first rotary member 210 may be formed at the center of rotation of the other end of the panel 110. Therefore, the other end of the panel 110 may rotate about the first rotating member 210 with respect to the vertical direction of the base 120. The other end of the panel 110 may be rotated about the width direction of the base 120 about the first rotary member 210.

The connection member 230 connects the base 120 to the panel 110 and supports the panel 110 with respect to the base 120. Therefore, it is preferable to form it so as to have sufficient rigidity.

As shown in FIGS. 7 and 8, the second rotary member 220 may be rotatable in two directions. FIG. 8 shows a state in which the panel 110 is rotated in the vertical direction, that is, in the thickness direction. 7 shows a state in which the panel 110 rotates about the width direction thereof. However, it is not limited to the number of such rotatable directions.

As described above, the second rotary member 220 is provided at the other end of the panel 110. The second rotary member 220 is connected to one end of the base 120 through a connection member 230. Therefore, rotation by the second rotary member 220 means rotation of the connection member 230, and rotation of the connection member 230 means rotation of one end of the base 120. Accordingly, the second rotating member 220 may be formed at the center of rotation of the base 120. Therefore, one end of the base 120 can rotate about the second rotating member 220 with respect to the vertical direction of the panel 110. One end of the base 120 may rotate about the second rotating member 220 with respect to the width direction of the panel 110.

However, as described above, the base 120 may be a fixed configuration. That is, a horizontal plane, a vertical plane, an inclined plane, or the like. Therefore, the rotation can be fixed to impossible. Accordingly, the panel 110 can be rotated with respect to the base 120 by the second rotating member 220. [ Specifically, one end of the panel 110 may be rotated with respect to the other end of the panel 110.

When the base 120 is fixed, the other end of the panel 110 may be rotated with respect to the first rotating member 210 and the other end of the panel 110 may be rotated with respect to the second rotating member 220. [ One end of which can be rotated.

The change in the position of the panel 110 through the first and second rotary members 210 and 220 will be described in detail with reference to FIG.

3, when the base 120 is fixed, the panel 110 maintains its posture through the first connecting member 210, that is, the angle of the panel 110 with respect to the base 120 Can be rotated without changing the rotation angle. It is also possible to change the angle of the panel 110 with respect to the base 120 by rotating the panel 110 through the first connecting member 210. Of course, the two rotations described above can be combined.

Meanwhile, the panel 110 is rotatable with respect to the base 120 through the second connection member 220. The first panel 110 may be rotated to change the angle between the connecting member 230 and the panel 110 through the second connecting member 220. [ The angle of the first panel 110 with respect to the base 120 may be changed through the second connection member 220. Of course, the two rotations described above can be combined.

The panel 110 can be changed into various positions and various postures through the structure of the fixed base 120, the two rotating members, and the panel 110 connected to the base 120 through the two rotating members. Therefore, it becomes possible to change the direction of providing illumination in a wide variety of ways. Further, it is possible to change the illumination direction in various ways irrespective of the installed environment.

The states shown in Figs. 2 and 3 are substantially the same. That is, there is only difference in whether the base 120 is fixed on a horizontal plane or on a vertical plane. Therefore, it can be seen that the conversion from the state shown in FIG. 1 to the state shown in FIG. 2 is not easy with only the characteristics of the first rotating member 210 and the second rotating member 220 described above. That is, it can be seen that the angle of the panel 110 with respect to the ground can not be changed. Therefore, it is preferable that the connecting member 230 is rotatable about the longitudinal direction in order to change an angle between the ground and the horizontal surface of the panel 110. [ That is, the connecting member 230 may have a rotatable joint structure 240 formed thereon. For example, this joint structure can be called a rotating joint.

Both sides of the connecting member 230 can be relatively rotated in mutually opposite directions about the joint structure 240. It means that the panel 110 rotates about its longitudinal direction on the assumption that the base 120 is fixed. Thus, it becomes possible to adjust the angle of the panel 110 with respect to the ground. More specifically, it becomes possible to adjust the angle of the front surface 111 of the panel 110 with respect to the ground.

Here, the joint structure 240 may be disposed adjacent to the panel 110. That is, it is preferable to form the joint structure 240 on the connecting member 230 adjacent to the panel 110. This is because the user will adjust the angle of the panel 110 by applying a force to the panel 110. Thus, the user can easily adjust the angle of the panel 110. Accordingly, the joint structure 240 may be provided with any one of the rotating members. In this case, any one of the rotary members may be rotatable in three directions.

It is preferable that the above-described rotary connection structures are made so that the user can easily operate them, and that the completed connection structure is maintained after the operation is completed. That is, it is desirable to maintain the state after the user has positioned the panel 110 at a specific angle and position. Thus, it is desirable that the rotationally connected structures have sufficient frictional force to withstand the weight of the illuminator configurations.

1 and 3, in a state in which the base 120 and the panel 110 are folded, the front surface 122 of the base 120 is in contact with the second rotary member 220, (111) can abut the first rotating member (210). This is because the rotating members may be provided so as to protrude from the front surface of the base and the panel, respectively. Therefore, it is preferable that the outer surfaces of the rotating members are made of a soft material or an elastic material in order to protect the base and the panel. Therefore, even in the folded state, the front surface of the base and the front surface of the panel can be protected due to the characteristics of the outer material of the rotating member.

In order to realize the above-described rotation characteristic, the rotation members 210 and 220 are preferably formed in a cylindrical shape or a spherical shape. Because of this shape feature, it will be easy to rotate in a plurality of directions. However, the larger the area of contact between the rotating members and the front surface of the base, especially the front surface of the panel, may be preferable. Therefore, a cylindrical shape rather than a spherical shape may be more preferable. The connecting member 230 may be connected to the circumferential surface of the rotating members.

Hereinafter, the rotatable structure of the first rotating member 210 or the second rotating member 220 will be described in detail with reference to FIGS. 9 and 10. FIG. Only the first rotating member 210 will be described for convenience of explanation. The second rotating member 220 may include the same components as the first rotating member 210 and may perform the same function.

As shown, the first rotary member 210 is rotatably connected to the base 120 first. Specifically, the first rotary member 210 is rotatably supported to the base 120 in the left-right direction. That is, rotatably supported on the basis of the vertical direction of the base 120. The left-right rotation of the first rotating member 210 can be realized through the left-right rotating shaft 280.

The left and right rotation shafts 280 may be provided perpendicular to the base 210. The left and right rotation shafts 280 may be formed into a rod shape. Therefore, there is a problem that the first rotary member 210 can not be rotatably supported with respect to the base 120 in a stable manner. Therefore, the rotation shaft base 282 for rotatably supporting the left and right rotation shaft 280 may be included. Since the support area is increased through the rotation shaft base 282, it becomes possible to more stably support the first rotation member 210 on the left and right rotation shaft 280 and further on the base.

The rotary shaft base 282 may be provided inside the base 120. The rotation shaft base 282 may be configured to rotate integrally with the left and right rotation shafts 280. Accordingly, the rotation shaft base 282 and the left and right rotation shaft 280 can rotate left and right with respect to the base 120. In other words, it can be said that the rotating shaft base 282 substantially rotates left and right with respect to the base 120.

The left and right rotary shaft 280 and the rotary shaft base 282 may not be exposed to the outside of the lighting apparatus 100, particularly to the outside of the first rotary member 210. Therefore, it is possible to realize a safe and beautiful appearance.

Specifically, the base 120 may include an upper base 123 and a lower base 124. The rotary shaft base 282 is interposed between the upper base 123 and the lower base 124 and can be supported to be rotatable in the left and right direction.

Here, the rotation angle of the rotary shaft base 282 with respect to the base 120 may be limited. This is because as the rotation angle becomes larger, a problem may arise in the electric wires supplying power to the panel 110. [ Therefore, the left-right rotation range of the first rotary member 210 can be realized through the structure between the rotary shaft base 282 and the base 120. [

This limitation of the left-right rotation angle can be variously implemented, and an example thereof is shown in Fig.

First, the base 120, particularly, the lower base 124 may be provided with a seating part 130 on which the rotary shaft base 282 is rotatably seated. The height of the seating part 130 may be the same as the height of the rotation shaft base 232. The upper base 123 covers the rotary shaft base 282, and the rotary shaft base 282 may be formed in a disc shape. Therefore, the rotating shaft base 282 can be stably supported within the base 120.

The shape of the rotary shaft base 282 has the following effects. The left-right rotation of the first rotary member 210 is preferably performed while overcoming a certain reaction force. This is because it is not preferable that the first rotary member 210 is rotated in the left-right direction even with a small external force.

Therefore, a rotational resistance frictional force can sufficiently be generated between the rotary shaft base 282 and the base 120 through the plate shape of the rotary shaft base 282. [

Here, a slot may be formed to limit the rotation angle of the rotary shaft base 282 to the left and right, and the rotary shaft base 282 may rotate left and right to a range limited by the slot. These slots can correspond to the protrusions, and the protrusions move between the slots to restrict their angle of rotation. Here, the slots and protrusions may be formed on the seating portion 130 and the rotary shaft base 282, respectively, and vice versa.

9 shows an example in which a slot 131 is formed in the seating part 130 and a projection 283 is formed in the rotary shaft base 282. [ As the rotary shaft base 282 rotates to the left and right, the protrusion 283 moves in the slot 131. However, when the protrusion 283 touches both ends of the slot 131, the rotating shaft base 282 can no longer rotate. Therefore, the left and right rotation range of the first rotary member 210 can be limited through the structure of the slot 131 and the protrusion 283.

The first rotary member 210 may include a front-rear rotary shaft 290 to rotate about the front-rear rotation of the first rotary member 210, that is, the width direction of the base 120. Specifically, the front and rear rotary shafts 290 may be formed perpendicular to the left and right rotary shafts 280.

The front and rear rotation shafts 290 may be provided on the left and right shafts 280. More specifically, the front-rear rotation shaft 290 may be provided at the center of the first rotary member 210. Therefore, the first rotating member 210 can be rotated back and forth with respect to the center portion thereof.

The first rotary member 210 may include housings 250 and 260 having an outer shape in order to assemble and smoothly view the rotary shafts 280 and 290. Specifically, the housing may include a front housing 250 and a rear housing 260. The front housing 250 and the rear housing 260 may be coupled to each other through fastening holes 255 and 265, or may be coupled to each other in various ways.

The housing may be configured to fix the rotating shafts 280 and 290 to the base 120, and may be configured to form the outer shape of the first rotating member 210 separately. For example, a cover (not shown) covering the outside of the housings 250 and 260 and the like may be included. As a result, the housing may have the function of connecting the first rotating member 210 to the base 120 and additionally the outer shape of the first rotating member 210.

The front housing 250 and the rear housing 260 are coupled to each other with reference to the rotational axes to form the outer shape of the first rotational member 210. Then, the above-described rotation shafts are accommodated therein.

The external power source is preferably transmitted to the panel 110 through the base 120. That is, the external power source may be transmitted to the base 120 through the electric wire and then to the panel 110 through the electric wire. Of course, the external wires may be omitted via a battery or charging system.

Here, the electric wire may be connected to the panel 110 through the first rotary member 210. For this purpose, it is preferable that a hollow 281 is formed at the center of the right and left rotary shaft 280. Accordingly, the wire may flow into the hollow portion 281 from the inside of the base 120, and then may be introduced into the connecting member 230 again. That is, although not shown, it is preferable that a hollow is also formed inside the connecting member 230. Accordingly, the wires can be sequentially connected to the base 120, the first rotating member 210, the connecting member 230, the second rotating member 220, and the panel 110.

Fig. 10 shows the cut surface of the first rotating member 210. Fig. As described above, the first rotary member 210 can be rotated back and forth with respect to the front-rear rotary shaft 290. However, this longitudinal rotation may not be easy due to the left-right rotation shaft 280. [ Therefore, it is preferable that a swing slot 270 in which the left and right rotation shafts 280 can swing is formed when the first rotation member 210 rotates with respect to the front and rear rotation shafts 290.

The swing slot 270 may be formed in the front housing 210 and the rear housing 220, respectively. Accordingly, the left and right rotation shafts 280 can swing in the swing slots 270. Of course, the center will be the longitudinal axis 290. The forward and backward rotation angle of the first rotary member 210 may be limited by the angle of the swing slot 270.

Here, the angle of the swing slot 250 may be 90 degrees or more. Therefore, the panel 110 can be completely folded on the base 120. [

As described above, in this embodiment, the projection direction can be easily changed with a mechanical structure. Also, various adjustments are possible in the selected lighting environment. This is because the front-rear rotation angle and the left-right rotation angle of the panel can be easily adjusted. In this embodiment, it is possible to implement various lighting conditions independently and in combination with these features.

The control unit 600 basically controls the operation of the illumination device 100. The control unit 600 can control the lighting conditions and the light emission conditions. The light emitting condition includes controlling the presence or absence of light emission.

A light emitting device, for example, an LED, is capable of changing the color of emitted light or changing the temperature of the emitted color in combination with one device itself or in combination with other devices. Then, it is easy to change the brightness of light, for example, illumination. Therefore, it is possible to easily change such an illumination condition or a light emission condition.

It is also very easy to automatically and automatically change these lighting conditions through a simple control algorithm.

Therefore, according to the present embodiment, the panel angle can be easily changed to vary the projection direction. In addition, it is possible to easily control an illumination condition or a light emission condition projected through the light emitting surface. That is, it becomes possible to control light emission conditions differently through the control unit. Therefore, various lighting conditions and conditions can be easily selected or changed by a user, so that it is possible to satisfy various lighting demands through a single lighting device.

Also, the controller 600 may control light emission conditions of light intensity, color temperature of light, or light color depending on the illumination environments.

Therefore, the lighting apparatus according to the present embodiment can be used not only as a lighting apparatus function but also as an interior accessory because it can change various indoor ambience.
