Description

Lamp stand and method for rotating the same {Lamp stand and method for rotating the same}

The present invention relates to a lighting stand, and more particularly, to a lighting stand capable of rotating a lighting unit in various directions and a method for rotating the same.

A lighting stand used indoors refers to a lighting device that illuminates the surroundings by turning on a lighting lamp by combining a lighting lamp such as an LED with a stand body.

As interest in space styling to arrange various types of home appliances in a desired combination according to individual tastes or needs increases, lighting stands are also required to be equipped with design and functionality.

However, the conventional lighting stand has limitations in providing an aesthetic sense due to its simple shape, and no effect other than a subtle lighting effect can be expected.

Conventionally, a number of lighting stands capable of changing shape or form have been disclosed.

Korean Patent Laid-open Publication No. 10-2016-0089098 (Prior Document 1) discloses an electric lamp that makes angle adjustment and rotation of a headlamp very easy by specially designing and changing the joint structure of the electric lamp.

Korean Patent Registration No. 10-1256183 (Prior Document 2) discloses an electric lamp that can easily adjust the vertical height and horizontal position of a lighting facility to a desired position by improving a connection structure.

Korean Patent Registration No. 10-0934750 (Prior Document 3) discloses an electric lamp that includes a first rotation means and a first rotation means that allow both vertical rotation and left-right rotation of a supporter relative to a support plate, and furthermore, a lamp unit that enables rotation in the vertical direction and a second rotation unit and second rotation means that allow the lamp unit to rotate in the left-right direction at the same time, so that the user can freely select a desired irradiation position, angle, and range.

Conventional lighting stands, including the prior literature, have disadvantages in that they have a simple design and that components must be manually rotated or changed in shape. In addition, conventional lighting stands have a problem in that they have limitations in exerting lighting effects due to limitations in the illumination angle.

An object of the present invention is to provide a lighting stand designed to implement lighting modes of various compositions by reflecting a unique design structure and a rotation method thereof.

An object of the present invention is to provide a lighting stand configured such that a lighting unit is rotatable in various directions and a method for rotating the same.

An object of the present invention is to provide a lighting stand and a rotation method thereof to minimize vibration generated when rotating a lighting unit.

An object of the present invention is to provide a lighting stand and a rotation method thereof to minimize the time required to rotate the lighting unit.

A lighting stand according to an embodiment of the present invention includes a pedestal, a support portion is connected to the pedestal, and a lighting assembly may be connected to the support portion. The lighting assembly includes a first rotation unit rotating in a first direction with respect to the support unit and a second rotation unit rotating in a second direction with respect to the first rotation unit, and the lighting unit may be installed in the second rotation unit. A plurality of LEDs may be installed in the lighting unit.

The first direction and the second direction may be directions different from each other, and preferably may be directions orthogonal to each other. The first rotation unit and the second rotation unit may rotate simultaneously or separately and independently of each other. The lighting unit may be rotated in various directions according to each rotation of the first rotation unit and the second rotation unit, and thus may illuminate in various directions.

When the first rotation unit and the second rotation unit each rotate, the rotational speed may vary for each of a plurality of sections. The plurality of sections may include a first section, a second section, and a third section. Of the total length of the plurality of sections, the first section and the third section may be 5 to 10% and the second section may be 90 to 95%.

The rotation of the first rotation unit and the second rotation unit may affect the shaking of the lighting stand when the lighting assembly rotates, and the rotation speed at that time may affect the rotation time of the lighting assembly. In the lighting stand of this embodiment, the rotational speed may be changed for each of a plurality of sections in consideration of shaking and rotational time during rotation of the lighting assembly. In this embodiment, it can rotate by accelerating in the first section, rotate at maximum speed in the second section, and rotate by decelerating in the third section. In particular, in order to optimize the shaking and rotation time, it can be rotated by decelerating to 20 to 40% of the maximum speed in the third section. More preferably, it is rotated by decelerating to 30% of the maximum speed in the third section.

When the first rotating unit rotates, the change in rotational speed in the first to third sections may be determined according to a result of sensing the sensing member by the plurality of sensing sensors. A sensing member may be installed in the first rotation unit, and a plurality of detection sensors for detecting the rotation of the sensing member by the rotation of the first rotation unit may be installed in the support unit. At this time, a plurality of detection sensors may be installed to correspond to the rotational path of the detection member.

When the first rotating part rotates, it accelerates and rotates until the first sensor of the plurality of sensors detects the sensing member, and when the first sensor detects the sensing member, it rotates at maximum speed and the second sensor senses the sensing member. When it is detected, it decelerates and rotates. That is, from the set initial position, until the first sensor detects the sensing member may be the first period, and after the first sensing sensor detects the sensing member, the second sensing sensor detects the sensing member. It may be the second period, and after the second sensor detects the sensing member, it may be the third period. Of the total length of the rotation path, the distance between the first detection sensor and the second detection sensor is 90 to 95%.

Rotation of the second rotating unit may be applied in the same manner. That is, when the second rotating part rotates, it accelerates and rotates until the third sensor of the plurality of sensors detects the sensing member, and when the third sensor detects the sensing member, it rotates at maximum speed and the fourth sensor senses the sensing member. When it is detected, it decelerates and rotates. Even during the rotation of the second rotating unit, the section rotating by acceleration becomes the first section, the section rotating at the maximum speed becomes the second section, and the section rotating by deceleration becomes the third section. In this way, when the first rotation unit and the second rotation unit rotate, the shaking and rotation time can be optimally adjusted by changing the rotation speed differently for each of a plurality of sections.

A lighting stand and a rotation method thereof according to an embodiment of the present invention have the following effects.

According to the present invention, since the lighting unit can be rotated in various directions, it can be illuminated in various directions.

According to the present invention, vibration according to rotation of the lighting unit can be minimized by adjusting the rotational speed when the lighting unit rotates.

According to the present invention, since the lighting unit can be rotated quickly, the time required for rotation can be minimized.

Hereinafter, some embodiments of the present invention will be described in detail through exemplary drawings. In adding reference numerals to components of each drawing, it should be noted that the same components have the same numerals as much as possible even if they are displayed on different drawings. In addition, in describing an embodiment of the present invention, if it is determined that a detailed description of a related known configuration or function hinders understanding of the embodiment of the present invention, the detailed description will be omitted.

The present invention relates to a lighting stand. The lighting stand of the present invention can illuminate light of various colors, and can enhance the interior effect by providing a C-shaped design as well as a lighting effect by adjusting the lighting angle by allowing the lighting unit to rotate in various directions.

Hereinafter, a lighting stand according to an embodiment of the present invention will be described in detail.

In FIGS. 1 and 2 , the lighting stand according to an embodiment of the present invention may include a pedestal 100 . The pedestal 100 may serve to stably support the lighting stand. The pedestal 100 may include a disc-shaped housing 110 having a space therein. Electronic components (not shown) capable of manipulating the light stand may be disposed in the inner space of the housing 110 . A plurality of button parts 111 may be formed on the upper surface of the housing 110 and a plurality of light emitting parts 112 respectively corresponding to the plurality of button parts 111 may be installed.

The button unit 111 may be installed so that a user can touch or press the button unit 111 to operate the lighting stand. When the user touches the button unit 111, functions allocated to the button unit 111 may be performed. For example, when the power button is touched, the lighting unit 322 to be described below may be turned on/off. Also, when the brightness button is touched, the brightness of the lighting unit 322 can be adjusted, and when the rotation button is touched, the lighting unit 322 can be rotated.

The light emitting unit 112 may emit light in response to a touch of the button unit 111 . Accordingly, the user can visually check whether the function assigned to the button unit 111 is performed. For example, when the power button is touched while the lighting unit 322 is off and the lighting unit 322 is turned on, the corresponding light emitting unit 112 emits light. Then, when the power button is touched once more to turn off the lighting unit 322, the corresponding light emitting unit 112 does not emit light.

The support 200 may be connected to the pedestal 100 . One end of the support 200 is connected to the pedestal 100 and the other end is connected to the lighting assembly 300 to be described below to serve to support the lighting assembly 300.

The support part 200 may have a tubular shape through which the inside is penetrated. Inside the support 200, a cable (not shown) connecting electronic components formed in the inner space of the pedestal 100 and elements constituting the lighting assembly 300 and a circuit may be disposed.

The support part 200 may include a first support part 210 connected to the pedestal 100, a second support part 220 connected to the first support part 210 to determine the height of the lighting assembly 300, and a third support part 230 connecting the second support part 220 and the lighting assembly 300.

The first support part 210 and the third support part 230 may be formed in a curved shape as a whole, and the second support part 220 may be formed in a straight line shape. Of course, these forms are examples and may be changed into various forms.

The lighting assembly 300 may be connected to the support 200 . The lighting assembly 300 may include a first rotation unit 310 connected to an end of the third support unit 230 and a second rotation unit 320 connected to an end of the first rotation unit 310 .

The first rotation unit 310 may rotate in the first direction with respect to the third support unit 230 . The second rotation unit 320 may rotate in the second direction with respect to the first rotation unit 310 . The first direction and the second direction may be different directions. Preferably, they may be orthogonal to each other.

The first rotating unit 310 may include a coupling unit 311 coupled to the third support unit 230 and a body unit 312 integrally formed with the coupling unit 311 . The body portion 312 may be formed to extend downward from the coupling portion 311 in a gentle curved shape.

A position in an initial state in which the first rotation unit 310 does not rotate with respect to the support unit 200 may be referred to as an initial position. That is, the initial position of the first rotation unit 310 is the angle formed by the first rotation unit 310 and the support unit 200 when looking at the front and back of the first rotation unit 310 and the support unit 200. It can be a position where it becomes 0 degree.

The second rotation unit 320 may be installed at an end of the first rotation unit 310 . The second rotation unit 320 may include a connection unit 321 partially overlapping the body unit 312 of the first rotation unit 310 and a lighting unit 322 coupled to an upper portion of the connection unit 321. The connecting portion 321 has a C-shape as a whole, and the lighting unit 322 may be installed while extending from an upper end of the connecting portion 321 .

Since the lighting unit 322 constitutes the lighting assembly 300, rotation of the lighting assembly 300 means that the lighting unit 322 rotates, and conversely, rotation of the lighting unit 322 means that the lighting assembly 300 rotates.

A position in an initial state in which the second rotation unit 320 does not rotate with respect to the first rotation unit 310 may be referred to as an initial position. That is, the initial position of the second rotation unit 320 is when the first rotation unit 310 and the second rotation unit 320 are viewed from the front and back, the angle between the second rotation unit 320 and the first rotation unit 310 is 0. It can be a position.

As shown in FIGS. 2 and 3 , when the first and second rotating parts 310 and 320 are at their initial positions, a part of them overlaps, and when the second rotating part 320 rotates, the overlapping parts can be unfolded. When the first and second rotating parts 310 and 320 are in their initial positions, the body part 312 and the connection part 321 may completely overlap each other.

A plurality of light emitting devices 323 may be disposed in the lighting unit 322 . The plurality of light emitting devices 323 may be arranged according to a certain rule. The light emitting element 323 may be, for example, an LED. In the drawing, the light emitting element 323 is installed on one side of the lighting unit 322 to illuminate in one direction, but may be installed at another location of the lighting unit 322 to illuminate in various directions.

Figures 3a to 3i is an exemplary view of the lighting assembly 300 is shown in a rotated state. 3A shows a state in which the first rotation unit 310 and the second rotation unit 320 are at their respective initial positions and are not rotated. That is, when the rotation angles of the first and second rotation units 310 and 320 are both 0 degrees, FIG. 3B shows a state in which the first rotation unit 310 is at an initial position and the second rotation unit 320 is rotated 90 degrees in the right direction. That is, the rotation angle of the first rotation unit 310 is 0 degrees and the rotation angle of the second rotation unit 320 is +90 degrees.

3C shows a state in which the first rotation unit 310 is at an initial position and the second rotation unit 320 is rotated 90 degrees in the left direction. That is, the rotation angle of the first rotation unit 310 is 0 degrees and the rotation angle of the second rotation unit 320 is -90 degrees.

3D shows a state in which the first rotation unit 310 is rotated 90 degrees in the right direction and the second rotation unit 320 is at an initial position. That is, the rotation angle of the first rotation unit 310 is +90 degrees and the rotation angle of the second rotation unit 320 is 0 degrees.

3E shows a state in which the first rotating unit 310 is rotated 90 degrees in the right direction and the second rotating unit 320 is also rotated 90 degrees in the right direction. That is, this is the case when both rotation angles of the first rotation unit 310 and the second rotation unit 320 are +90 degrees.

3F shows a state in which the first rotation unit 310 rotates rightward by 90 degrees and the second rotation unit 320 rotates leftward by 90 degrees. That is, the rotation angle of the first rotation unit 310 is +90 degrees and the rotation angle of the second rotation unit 320 is -90 degrees.

3G shows a state in which the first rotation unit 310 is rotated 90 degrees in the left direction and the second rotation unit 320 is at an initial position. That is, the rotation angle of the first rotation unit 310 is -90 degrees and the rotation angle of the second rotation unit 320 is 0 degrees.

3H shows a state in which the first rotation unit 310 rotates leftward by 90 degrees and the second rotation unit 320 rotates rightward by 90 degrees. That is, the rotation angle of the first rotation unit 310 is -90 degrees and the rotation angle of the second rotation unit 320 is +90 degrees.

3I shows a state in which the first rotation unit 310 is rotated 90 degrees in the left direction and the state in which the second rotation unit 320 is also rotated 90 degrees in the left direction. That is, this is the case when both rotation angles of the first rotation unit 310 and the second rotation unit 320 are -90 degrees.

Rotation directions of the first rotation unit 310 and the second rotation unit 320 may be different from each other. Each rotation direction of these may be orthogonal. The first rotation unit 310 and the second rotation unit 320 may rotate simultaneously or separately. The first rotation unit 310 and the second rotation unit 320 may rotate independently of each other. For example, only the second rotation unit 320 may rotate without rotating the first rotation unit 310, and conversely, only the first rotation unit 310 may rotate without rotating the second rotation unit 320. As such, the lighting stand according to the present embodiment can be transformed in various shapes and the lighting direction can be changed in various directions by independently rotating the first rotation unit 310 and/or the second rotation unit 320.

The first rotation assembly 400 may be installed inside the coupling part 311 where the third support part 230 and the first rotation part 310 are coupled. The role of the first rotation assembly 400 is to connect the third support unit 230 and the first rotation unit 310 and simultaneously allow the first rotation unit 310 to rotate with respect to the third support unit 230 . Similarly, the second rotation assembly 500 may be disposed at a portion (B) where the first rotation unit 310 and the second rotation unit 320 are connected. The role of the second rotation assembly 500 is to connect the first rotation unit 310 and the second rotation unit 320 and at the same time allow the second rotation unit 320 to rotate with respect to the first rotation unit 310 .

As such, the lighting stand according to the present invention may have various shapes. In addition, when the lighting stand has various shapes, an angle of a range in which the lighting unit 322 irradiates light may be changed. Therefore, the lighting stand does not stop at merely irradiating light onto a desk or table, but also may be used as indirect lighting by irradiating light toward a wall, or may function as a kind of interior accessory. In addition, in the present invention, while the first rotation unit 310 and the second rotation unit 320 automatically rotate over time, aesthetics of the lighting stand and the surrounding area may be enhanced.

3A to 3I show a form in which the first rotation unit 310 and the second rotation unit 320 are rotated at intervals of 90 degrees, respectively. Unlike this, the first rotation unit 310 and the second rotation unit 320 can also change the angle more precisely. In addition, the first rotation unit 310 and the second rotation unit 320 may be rotated at an angle of 90 degrees or more.

The configuration of the first rotating assembly 400 is shown in FIGS. 4 to 6 .

At the end of the third support part 230, a protruding part 231 may protrude and extend forward. A bearing 401 may be coupled to surround an outer circumferential surface of the protrusion 231 . A bracket 410 may be inserted and fixed inside the end of the third support part 230 .

A first motor 402 may be inserted into the central portion of the bracket 410 . The first motor 402 may be fixed to the bracket 410 by a motor screw 403 . A first rotational shaft 405 may protrude and be installed in the first motor 402 . The first rotational shaft 405 may be installed to protrude to the outside of the bracket 410 by a predetermined length. The first motor 402 may be driven by a controller 600 to be described below.

A plurality of holes 401a may be formed at regular intervals on the side surface of the bearing 401 . A screw thread may be formed on an inner circumferential surface of the hole 401a. The coupling part 311 may be coupled to the bearing 401 while surrounding the outer circumferential surface of the bearing 401 . The bearing 401 and the coupling part 311 may be coupled and fixed by a bearing screw 404 . A plurality of through holes 313 may be formed in the center of the coupling part 311 .

A rib 314 may be formed at a predetermined height in the direction of the through hole 313 on an inner circumferential surface of the coupling part 311 , and a plurality of holes 315 may be formed in the rib 314 . Here, the hole 401a formed in the bearing 401 and the hole 315 formed in the rib 311 may correspond to each other.

An internal gear 406 may be fixed to the inner surface of the rib 314 by an internal gear screw 407, and an outer surface of the rib 314 may be fitted into the coupling part 311 so as to come into contact with the side surface of the bearing 401. As a result, the third support part 230 and the coupling part 311 may be coupled. The bearing screw 404 passes through the hole 315 formed in the rib 314 to increase the bonding force between the third support part 230 and the coupling part 311 and is inserted into the hole 401a formed on the side surface of the bearing 401 and coupled.

An axis gear 408 may be coupled to the first rotation shaft 405 of the first motor 402 . Here, when the first motor 402 is driven, the first rotational shaft 405 is rotated, and the rotational force of the first rotational shaft 405 can be transmitted to the shaft gear 407 .

The power transmission gear 409 is engaged with the shaft gear 408 and the power transmission gear 409 is simultaneously engaged with the internal gear 406 . The rotational force transmitted to the shaft gear 408 may be transmitted to the internal gear 406 through the power transmission gear 409 . Since the internal gear 406 is fixed to the coupling part 311 of the first rotation unit 310 by the internal gear screw 407, the rotational force transmitted to the internal gear 406 rotates the first rotation unit 310.

6, the bracket 410 to which the first motor 402 is mounted is installed inside the third support part 230, and after the coupling part 311 is coupled to the third support part 230, the internal gear 406 is fastened. It shows a form.

As shown in FIG. 7 , a plurality of sensing members 411 may be installed on the front of the bracket 410 . A detection sensor 412 may be installed on the front of the first rotation unit 310 to correspond to the plurality of detection members 411 . When the first rotation unit 310 rotates, the detection sensor 412 may also rotate together. In this case, the plurality of detection members 411 may be disposed to correspond to a virtual rotation path formed when the detection sensor 412 rotates. In this embodiment, four sensing members 411 are disposed.

In the sensing member 411, the first sensing member 4111 and the second sensing member 4112 may be installed in the left direction with respect to the initial position P, and the third sensing member 4113 and the fourth sensing member 4114 may be installed in the right direction. The detection sensor 412 rotates along a virtual rotation path corresponding to the position where the first to fourth sensing members 4111 to 4114 are disposed, but rotates along the left rotation path A when rotating to the left. When rotating to the right, it can rotate along the right rotation path B. When the detection sensor 412 detects the first to fourth detection members 4111 to 4114 as they rotate along the rotation paths A and B, the detection result may be transmitted to the control unit 600 .

8 and 9 show a second rotary assembly 500.

The lower frame 521 is installed according to the shape of the body portion 312 of the first rotating body 310, and the end of the lower frame 521 to which the first rotating portion 310 and the second rotating portion 320 are connected. Through-holes 513 may be formed. A cylindrical rotating body 510 may be inserted into the through hole 513 . The cable C may be inserted into the rotating body 510 and pass through the rotating body 510 . The cable (C) is for connecting the electronic components of the pedestal 100 and the elements and circuits constituting the second rotating part 320 . At this time, a protective member 523 may be inserted into the inner circumferential surface of the rotating body 510 so that the cable C can be stably maintained even when the rotating body 510 rotates.

The rotating body 510 may be rotated inside the through hole 513 by a second motor 502 to be described below. A bearing (not shown) may be disposed on an outer circumferential surface of the rotating body 510 to rotate the rotating body 510 . The rotating body 510 can rotate smoothly in the through hole 513 of the lower frame 521 by the bearing. Also, a power transmission gear 506 may be installed below the rotating body 510 .

A second motor 502 may be provided at a lower portion of the body portion 312 of the first rotating body 310 . A second rotational shaft 505 may protrude and be installed in the second motor 502 . An axis gear 508 may be coupled to the second rotational shaft 505 . The shaft gear 508 may mesh with the power transmission gear 506 . In this structure, when the second motor 502 is driven, the second rotational shaft 505 rotates, and the rotational force of the second rotational shaft 505 can be transmitted to the power transmission gear 506 through the shaft gear 508. In this way, the rotating body 510 may be rotated by the rotational force transmitted to the power transmission gear 506 . The rotating body 510 is connected to the connecting portion 321 of the second rotating portion 320, and as the connecting portion 321 rotates by the rotational force of the rotating body 510, the second rotating portion 320 rotates.

Referring to FIG. 9 , a rotating body 510 may protrude through a through hole 513 on the upper surface of the lower frame 521 . In addition, a rib 514 may be installed on the upper surface of the lower frame 521 . A detection sensor 512 may be fixedly installed on the upper surface of the rib 514 . The detection sensor 512 may be installed to protrude in a certain length. The detection sensor 512 may detect the plurality of detection members 511 shown in FIG. 10 .

10 shows a lower surface of the upper frame 321b constituting the connection part 321 of the second rotating part 320. The upper frame 321b may be fixedly coupled to the rotating body 510 . Therefore, when the rotating body 510 rotates, the upper frame 321b rotates together, so that the second rotating part 320 rotates. Even when the rotating body 510 rotates, the separately installed detection sensor 512 is fixed.

Looking at the lower surface of the upper frame 321b, a plurality of sensing members 511 are installed. When the upper frame 321b is coupled to the lower frame 521, the detection sensor 512 may correspond to the plurality of detection members 411. Specifically, when the upper frame 321b rotates together with the rotation of the rotating body 510, the plurality of sensing members 511 also rotate. At this time, the detection sensor 512 may be located in the rotation path of the detection member 511 . Conversely, the detection sensor 512 may be on the rotation path of the plurality of detection members 511 .

That is, similar to FIG. 7 , when the plurality of sensing members 511 rotate, the sensing sensor 512 may form a virtual rotation path when viewed from the sensing member 511 . In this embodiment, four sensing members 511 are disposed.

7, in the sensing member 511, the first sensing member 5111 and the second sensing member 5112 may be installed in the left direction with respect to the initial position P, and the third sensing member 5113 and the fourth sensing member 5114 may be installed in the right direction. The detection sensor 512 moves along a virtual rotation path formed in the first to fourth sensing members 5111 to 5114, but moves along the rotation path A on the left when rotating to the left and rotates to the right. In the case of rotation, it can move along the rotation path B on the right. Of course, it can be seen that the sensor 512 moves relatively with respect to the sensing member 511 by moving the sensing member 511 rather than actually moving the sensor 512 . When the detection sensor 512 detects the first to fourth detection members 5111 to 5114 on the rotation paths A and B, the detection result may be transmitted to the control unit 600.

As described above, the first rotation unit 310 may rotate in a first direction relative to the support unit 200, and the second rotation unit 320 may rotate in a second direction relative to the first rotation unit 310. When the first rotation unit 310 and the second rotation unit 320 each rotate, the rotation speed may vary for each section.

The plurality of sections may be determined by the positions of the plurality of sensing members 411, and the rotational speeds of the first and second rotation units 310 and 320 are detected by the sensor 412 of the plurality of sensing members 411. It may be determined according to the result.

Since the rotation speed change of the first rotation unit 310 is applied equally to the rotation speed change of the second rotation unit 320, the rotation speed change of the first rotation unit 310 will be described below.

The structure and action between the sensing member 411 and the sensor 412 in the first rotating part 310 are the same as the structure and action between the sensing member 511 and the sensor 512 in the second rotating part 320. Therefore, the structure and operation of the sensing member 411 and the detection sensor 412 in the first rotation unit 310 will be described below, and the sensing member 511 and the detection sensor 512 of the second rotation unit 320 are equally applied.

As shown in FIG. 11 , the plurality of sensing members 411 may be installed on the radius of a semicircle, two in the left direction and two in the right direction with respect to the reference position P as the center. A detection sensor 412 may be installed to correspond to this radius. When the first rotation unit 310 rotates, the detection sensor 412 also rotates together. In this case, the plurality of detection members 411 may be disposed to correspond to a virtual rotation path formed when the detection sensor 412 rotates. In this embodiment, four sensing members 411 are disposed.

The detection sensor 412 may be, for example, a hall sensor and the detection member 411 may be a magnet. In order to allow the sensing member 411 to be positioned within the sensing distance of the sensing sensor 412, the sensing sensor 412 may be installed at the end of the protruding member 413 protruding from the front of the first rotation unit 310.

Referring to FIG. 11 , when the first rotation unit 310 is at the initial position P, the detection sensor 412 may be disposed at the center of the four detection members 411 . That is, when the detection sensor 412 is positioned at the center of the four detection members 411, the initial position P of the first rotation unit 310 is reached.

The first rotating part 310 may be rotated in a rightward direction or a leftward direction from the initial position (P), respectively. In this embodiment, the maximum rotation angle in the right and left directions may be 90 degrees. Of course, in other examples, the maximum rotation angle may be changed.

Among the four sensing members 411, the first sensing member 4111 and the second sensing member 4112 are installed in the left direction at the initial position P in the center, and the third sensing member 4113 and the fourth sensing member 4114 may be installed in the right direction at the initial position P in the center. Thus, the first sensing member 4111 and the second sensing member 4112 are installed to correspond to the virtual leftward movement path A formed when the sensor 412 rotates leftward from the initial position P, and the third sensing member 4113 and the fourth sensing member 4114 form a virtual rightward rotation path B formed when the sensor 412 rotates rightward from the initial position P. It is installed to correspond to .

When the sensor 412 rotates leftward along the left rotation path A from the initial position P, the sensor 412 detects the first sensing member 4111 first, and continues to rotate. The sensor 412 senses the second sensing member 4112.

Similarly, when the sensor 412 rotates in the right direction along the right rotation path B from the initial position P, the sensor 412 detects the third sensing member 4113 first, and continues to rotate. The sensor 412 senses the fourth sensing member.

In this case, when the first rotating unit 310 rotates leftward or rightward from the initial position P, the rotational speed may be changed for each of a plurality of sections. For example, it may rotate at a first speed in the first section, at a second speed in the second section, and at a third speed in the third section. The first, second and third speeds may be different rotational speeds.

In this embodiment, it rotates by accelerating in the first section, rotates at maximum speed in the second section, and rotates by decelerating in the third section. That is, the first speed is accelerated, the second speed is the maximum speed, and the third speed is decelerated. At this time, when accelerating and rotating in the first section, it is preferable to accelerate to the maximum speed at the start position of the second section.

At this time, the first, second, and third speeds may be determined according to a result of the detection sensor 412 detecting the plurality of detection members 411 . For example, when the first rotation unit 310 rotates in the left direction at the initial position P, the first rotation unit 310 accelerates and rotates until the sensor 412 detects the first sensing member 4111 at the initial position P, rotates at maximum speed when the first sensing member 4111 is detected, and decelerates when it detects the second sensing member 4112.

The change of the first, second and third speeds is the same even when rotating in the right direction. That is, when the first rotation unit 310 rotates in the right direction from the initial position P, it accelerates and rotates until the sensor 412 detects the third sensing member 4113, and then detects the third sensing member 4113. When it detects, it rotates at the maximum speed, and when it detects the fourth sensing member 4114, it decelerates and rotates.

As shown in FIGS. 9 and 10 , the left rotation path A may further extend a predetermined distance from the second sensing member 4112 and the right rotation path B may further extend a predetermined distance from the fourth sensing member 4114. A left stopper 421 and a right stopper 422 may be installed at each extended end. Rotation may be stopped by the stoppers 421 and 422 while the sensor 412 decelerates in the third section. The left stopper 421 and the right stopper 422 are formed at 90 degree positions in the left and right directions from the initial position P, respectively. Buffer members (not shown) may be installed in the left/right stoppers 421 and 422 . Thus, when the sensor 412 collides with the stoppers 421 and 422, impact can be minimized by the buffer member.

In the left rotation path A, the first section may be from the initial position P to the first sensing member 4111, the second section may be from the first sensing member 4111 to the second sensing member 4112, and the third section may be from the second sensing member 4112 to the left stopper 421.

Similarly, in the right turn path B, the first section may be from the initial position P to the third sensing member 4113, the second section may be from the third sensing member 4113 to the fourth sensing member 4114, and the third section may be from the fourth sensing member 4114 to the right stopper 422.

In this embodiment, the plurality of sections may be divided into a first section, a second section, and a third section in turn in the left turn path (A) and the right turn path (B). The lengths of the first, second and third sections may be different. Compared to the first and third sections, the length of the second section may be longer.

In this embodiment, the length of the first section and the third section of the total length of the plurality of sections may be 5 to 10%, and the length of the second section may be 90 to 95%. Therefore, most of the first and second rotating parts 310 and 320 can be rotated at the maximum speed. Accordingly, the rotation time required to rotate the first and second rotation units 310 and 320 by 90 degrees can be minimized. If the length of the second section is short or it does not rotate at the maximum speed, it may take a long time to rotate 90 degrees.

As such, when rotating the first and second rotating parts 310 and 320 90 degrees in the left and right directions in this embodiment, changing the rotational speed in "acceleration → maximum speed → deceleration" occurs during rotation. It is to minimize the shaking and rotation time of the assembly 300 at the same time.

In the case of the lighting stand of this embodiment, the shaking and rotation time of the lighting assembly 300 may be determined according to the degree of deceleration of the rotational speed in the third section. Accordingly, shaking and rotating time of the lighting assembly 300 were confirmed through experiments while adjusting the rotational speed decelerated in the third section, and the results are shown in Table 1 below.

As shown in the results of Table 1 above, when comparing shaking and rotation time, it can be seen that the shaking and rotation time are determined by the speed of rotation by decelerating in the third section because the first section and the second section are all under the same conditions.

As shown in Table 1, when both shaking and rotation time are optimal, rotation is performed by decelerating to 30% of the maximum speed in the third section. Of course, in another embodiment, if the shake is set to 'low' and the rotation time is set to 'medium', or the shake is set to 'medium' and the rotation time is set to 'low' in consideration of the shake and rotation time to some extent, it may be rotated by decelerating to 20 to 40% of the maximum speed in the third section.

In the first, second, and third sections described above, the rotational speed change of "acceleration → maximum speed → deceleration" is applied not only when rotating in the direction of the first section to the third section, but also when rotating in the direction of the first section in the third section. The same can be applied.

The communication unit 601 may receive an operation command of the lighting stand from an external device and transmit it to the control unit 600 . The operation command may include, for example, power on/off, brightness control of the lighting unit, and the like.

The communication unit 601 may include a communication module for at least one of infrared communication, Wi-Fi communication, Bluetooth communication, and NFC communication, and may also be connected to an Internet network, LTE, and 5G networks through an AP device (not shown). A user may be able to communicate with the lighting stand in a remote place through such a network using a smart phone.

The button unit 111 may receive a user manipulation. The user may input an operation command of the lighting stand by touching or pressing the button unit 111 . For example, the operation command may include power on/off, brightness control of a lighting unit, and the like. The button unit 111 may transmit an operation command input by a user to the control unit 600 .

Brightness control may include gradual control and continuous control. The gradual adjustment is to adjust the brightness step by step by touching the brightness control button once, and the continuous control is to continuously adjust the brightness by continuously touching the brightness control button.

The control unit 600 receives detection signals for the sensing members 412 and 512 sensed from the plurality of sensors 411 and 511 installed on the first rotation assembly 400 and the second rotation assembly 500, respectively. It can drive the first motor 402 and the second motor 502.

The control unit 600 may adjust the driving speed of the first and second motors 402 and 502 . To this end, the control unit 600 can adjust the operating voltage applied to the first and second motors 402 and 502 by changing the resistance using a variable resistor when applying a driving current to the first and second motors 402 and 502, thereby adjusting the driving speed of the first and second motors 402 and 502. The rotation speed of the first and second rotation shafts 405 and 505 may be adjusted by adjusting the driving speed of the first and second motors 402 and 502 . In addition, the controller 600 may adjust the driving directions of the first and second motors 402 and 502 .

In addition, the controller 600 may control the lighting unit 330 according to an operation command transmitted through the button unit 111 and/or the communication unit 601 . That is, the LED of the lighting unit 330 may emit light. The control unit 600 may adjust the light emission intensity of the LED by adjusting the voltage applied to the lighting unit 300 . The LED may emit various colors by employing a colored light emitting device.

The memory 602 may store programs and data required for operation of the lighting stand.

For example, information on how much operating voltage is required for the sensing members 412 and 512 to rotate at a specific angle may be stored. In addition, the memory 602 \ may store information on the initial position P and the current position of the sensing members 412 and 512 . Since the position of the sensing members 412 and 512 changes according to an operation command, the current position can be updated and stored in real time.

13 is a flowchart illustrating a method of rotating a lighting stand according to an embodiment of the present invention.

Since the method of rotating the first rotation unit 310 relative to the support unit 200 and the method of rotating the second rotation unit 320 relative to the first rotation unit 310 are the same, FIG. 9 shows a method of rotating the first rotation unit 310.

When an operation command for rotating the first rotating unit 310 is input (S101), the controller 600 drives the first motor 402 to rotate the first rotating unit 310 (S102). This rotation may start from the initial position (P). The operation command includes rotation direction information of the first rotating unit 310 . Therefore, the control unit 600 can rotate according to the input rotation direction.

As the first rotation unit 310 rotates, the sensing member 412 installed on the first rotation unit 310 may also rotate together. At this time, in step S102, the first rotation unit 310 is accelerated and rotated. This accelerated rotation may continue until the first sensor among the plurality of sensors 411 detects the sensing member 412 . When the first rotating part 310 rotates leftward from the initial position P, the first detection sensor may be the first detection sensor 4111, and conversely when it rotates rightward, the first detection sensor may be the third detection sensor 4113.

When the first sensor detects the sensing member 412 (S103), the control unit 600 drives the first motor 402 to rotate the first rotation unit 310 at the maximum speed (S104). This maximum speed rotation may be continued until the second sensor among the plurality of sensors 411 detects the sensing member 412 . When the first rotation unit 310 rotates in the left direction, the second sensor may be the second sensor 4112, and conversely, if it rotates in the right direction, the second sensor may be the fourth sensor 4114.

When the second sensor detects the sensing member 412 (S105), the control unit 600 drives the first motor 402 to decelerate and rotate the first rotation unit 310 (S106). At this time, in step S107, the speed may be reduced to 20 to 40% of the maximum speed. More preferably, shaking and rotating time of the lighting stand can be minimized by rotating at a rate of 30% of the maximum speed.

When the sensing member 412 reaches the stopper 421 or 422 in a state in which the rotational speed is reduced (S107), the control unit 600 stops the driving of the first motor 402 to stop the rotation of the first rotating unit 310 (S108).

Although FIG. 13 discloses a method of rotating the first rotation unit 310, the method of rotating the second rotation unit 320 is the same as described above. And, both the first rotation unit 310 and the second rotation unit 320 can be rotated simultaneously and independently of each other.

That is, within the scope of the purpose of the present disclosure, all of the components may be selectively combined with one or more to operate.
