FIG. 1 is a configuration diagram of a lifting-type light lighting device according to an embodiment of the present invention, and FIGS. 3A and 3B are exemplary diagrams for explaining a lifting unit and a display unit of the lifting-type lighting device according to FIG. 1 .

1 and 3, the lifting type light lighting device 100 according to the embodiment of the present invention includes an upper body 110, a lower body 120, a lifting unit 130, a display unit 140, and a control unit ( 150).

The upper body 110 is upper and lower coupled to the lower body 120, and is moved up and down by an elevating unit 130 to be described later. In this case, the elevating unit 130 may connect the upper body 110 and the lower body 120 to elevate the upper body 110 from the lower body 120 . The upper body 110 may output one or more lights. In this case, the upper body 110 is arranged in the form of n × m LEDs can output symbols, characters, figures and the like. For example, in the case of outputting a warning light, red and blue LEDs may be output at preset cycles.

The lower body 120 is fixed to the roof (not shown) of the vehicle. The lower body 120 is positioned below the upper body 110 to support the upper body 110. In this case, inside the lower body 120, an internal space capable of accommodating the elevation unit 130, the display unit 140, and the control unit 150 is formed. In addition, a plurality of LEDs are accommodated in the lower body 120, like the upper body 110, to output light. In addition, speakers are built into both sides of the lower body 120 to output a sound effect such as a siren, or connected to a microphone to output a user's voice to the outside.

The elevating unit 130 is formed in a folding structure in which one side is connected to the upper body 110 and the other side is connected to the lower body 120 to elevate the upper body 110 . More specifically, the elevation unit 130 may be implemented by including a pair of connecting shafts 131, a plurality of frames 132, a connecting gear 134, and a first driving motor 131-6. The pair of connecting shafts 131 may be formed such that the first connecting shaft 131-1 and the second connecting shaft 132-2 face each other. A pair of connecting shafts 131 are connected to a plurality of frames 132 .

The plurality of frames 132 are connected to a pair of connecting shafts 131-1 and 131-2 and are formed by crossing each other in an X shape. In this case, the plurality of frames 132 may be repeatedly stacked in an X shape. This may vary depending on the height at which the upper body 110 is elevated. Accommodating grooves 132-3 may be formed on one side of the plurality of frames 132. Receiving grooves 132-3 may be formed in adjacent frames 132, respectively. A spring 135 is inserted into the receiving groove 132-3 so that the frame 132 is compressed when folded and easily unfolded by an elastic force when unfolded. Accordingly, the upper body 110 can be easily lifted with little force.

The connecting gear 134 is formed by a combination of a plurality of gears. The connecting gears 134 are formed on the connecting shafts 131-1 and 131-2, respectively. When the connection gear 134 is rotated by the driving motor 131-6, the heights of the plurality of frames 132 are adjusted. In this case, the connecting shafts 131-1 and 131-2 are connected to the auxiliary shafts 131-11 and 131-12 to rotate. In other words, while the auxiliary shafts 131-11 and 131-12 are rotated by the rotation of the connection gear 134, the plurality of frames 132 can be unfolded or folded. In FIG. 2 , (a) represents a state in which the plurality of frames 132 are unfolded, and (b) represents a state in which the plurality of frames 132 are folded.

The first drive motor 131-6 rotates the connection gear 134 so that the plurality of frames 132 are folded or unfolded. The first drive motor 131 - 6 can rotate in the forward and reverse directions and can be connected to the connection gear 134 in various ways. A method of rotating the connecting gear by the first driving motor 131-6 may be varied by a person skilled in the art.

As another embodiment, the lifting unit 130 includes a first driving unit 131 and a plurality of frames 132 as shown in FIG. 3 . The first driving unit 131 provides a driving force so that the plurality of frames 132 to be described later can be folded or unfolded. The first driving unit 131 of the elevation unit 130 includes a first connecting shaft 131-1, a second connecting shaft 131-2, a screw shaft 131-3, a sprocket 131-4, a chain ( 131-5) and a first driving motor 131-6. The first connection shaft 131-1 is formed in a circular bar shape. Both sides of the first connecting shaft 131-1 are fixed to rails formed inside the lower body 120. In addition, both sides of the first connecting shaft 131-1 are fixed to rails formed inside the upper body 110.

The second connection shaft 131-2 is formed in a circular bar shape. Both sides of the second connecting shaft 131-2 are disposed on the rails of the lower body 120, respectively. In this case, rollers are formed on both sides of the second connecting shaft 131-2 and move along the rails of the lower body 120. In addition, both sides of the second connecting shaft 131-2 are disposed on the rails of the upper body 110. In this case, rollers are formed on both sides of the second connecting shaft 131-2 and move along the rails of the upper body 110.

The screw shaft 131-3 connects the first connecting shaft 131-1 and the second connecting shaft 131-2. Specifically, a pair of screw shafts 131-3 are spaced apart and connect one side and the other side of the first connecting shaft 131-1 and the second connecting shaft 131-2, respectively. In this case, the screw shaft 131-3 may be connected orthogonally to the first connecting shaft 131-1. The screw shaft 131-3 rotates by receiving the driving force of the first drive motor 131-6 to be described later, and moves the second connecting shaft 131-2 closer to the first connecting shaft 131-1. You can move it away or away from it.

For example, the screw shaft 131-3 is threaded on the outside. In this case, through-holes are formed on one side and the other side of the first connecting shaft 131-1, respectively. In addition, screw holes corresponding to the through holes of the first connecting shaft 131-1 are formed on one side and the other side of the second connecting shaft 131-2, respectively. At this time, one side of the screw shaft 131-3 passes through the through hole of the first connecting shaft 131-1 and then is screwed into the screw hole of the second connecting shaft 131-2. In this case, the screw shaft 131-3 rotates and moves the second connecting shaft 131-2 closer to or farther from the first connecting shaft 131-1.

The sprockets 131-4 are formed at each end of the screw shaft 131-3 to rotate the screw shaft 131-3 in a forward or reverse direction by a chain 131-5. In addition, the first driving motor 131-6 is connected to one side of the screw shaft 131-3. In this case, the first driving motor 131-6 may transmit driving force to the screw shaft 131-3 to rotate the screw shaft 131-3.

The plurality of frames 132 are connected by folding by crossing the 'X' character to which the central axis is connected. Specifically, the plurality of frames 132 include a first frame 132-1 and a second frame 132-2. The first frame 132-1 has one side connected to the first connection shaft 131-1 and the other side connected to the second connection shaft 131-2. In addition, the second frame 132-2 has one side connected to the first connection shaft 131-1 and the other side connected to the second connection shaft 131-2. In this case, the plurality of frames 132 may unfold the upper body 110 from the lower body 120.

For example, as the screw shaft 131-3 receiving driving force from the first drive motor 131-6 rotates, the second connection shaft 131-2 is brought closer to the first connection shaft 131-1. It is possible to raise the upper body 110 by moving in the losing direction. In addition, the first driving motor 131-6 rotates the screw shaft 131-3 in the opposite direction to move the second connecting shaft 131-2 in a direction away from the first connecting shaft 131-1. The upper body 110 can be lowered.

On the other hand, it can be formed in a structure that connects a plurality of frames 132 bellows. Preferably, the plurality of frames 132 may be connected in three stages of folding, but the number is not limited. In this case, a plurality of frames 132 may be formed by a pair spaced apart between the lower body 120 and the upper body 110 .

In the display unit 140, a plurality of electronic display boards 141 and 142 are fixed to one side of the elevation unit 130 so that when the elevation unit 130 ascends, the display unit 140 vertically unfolds from the ground, and when descending, it can be folded horizontally from the ground. Specifically, the plurality of electronic display boards 141 and 142 include a first electronic display board 141 and a second electronic display board 142 . The first electronic display board 141 and the second electronic display board 142 have a rectangular box shape, and a plurality of LEDs are arranged inside. For example, a plurality of LEDs may be arranged in an n×m form to output symbols, characters, figures, and the like.

In this case, the first electronic display board 141 and the second electronic display board 142 may be connected by a hinge 143 . For example, the hinge 143 connects one side of the first electronic display board 141 and the second electronic display board 142, respectively. In this case, both sides of the first electronic display board 141 and the second electronic display board 142 may be rotatably connected to the central axis of the plurality of frames 132 . For example, when the plurality of frames 132 rise, the first electronic display board 141 and the second electronic display board 142 are vertically unfolded around the central axis of the hinge 143 . In addition, when the plurality of frames 132 descend, they may be horizontally folded around the central axis of the hinge 143 .

Preferably, the display unit 140 installed on the elevating unit 130 may be formed to extend toward the front of the vehicle, but may also be formed to extend toward the rear of the vehicle. In addition, the plurality of electronic display boards 141 and 142 may be formed in two or more. For example, it is also possible to form a plurality of folds or unfolds in a zigzag shape.

The control unit 150 controls the elevation unit 130 and the display unit 140 and is installed inside the lower body 120 . However, it is not limited thereto and the controller 150 may be installed inside the upper body 110. Preferably, the control unit 150 controls the operation of at least one of the upper body 110, the lower body 120, the elevation unit 130 and the display unit 140 as a control circuit.

Specifically, the control unit 150 can control the lighting pattern of the upper body 110 and the lower body 120, the lighting time and brightness, and the amplification ratio of the speaker. Also, the control unit 150 may control the first driving unit 131 to raise or lower the elevation unit 130 . In this case, the control unit 150 may control the lifting unit 130 to move the upper body 110 up and down when the speed is below a certain speed using a speed sensor or the like. For example, when the vehicle travels at a speed higher than or lower than a predetermined speed on the road, the upper body 110 may be raised to induce a direction to a rear vehicle.

In addition, the control unit 150 may control the lighting pattern and lighting time of the LEDs of the display unit 140 . In this case, the control unit 150 may control the lighting time in a pulse width modulation (PWM) method. For example, the controller 150 may control the development of the display unit 140 or control the LED pattern to be turned on so that the double-headed arrow (↔) and the one-way arrow (→, ←) are displayed on the display unit 140. Accordingly, it is possible to selectively guide the direction to a following vehicle according to traffic conditions on the road.

FIG. 4 is an exemplary view for explaining that the elevating light lighting device according to FIG. 1 further includes a rotation display unit, and FIG. 5 shows a state in which the upper body and the lower body are sealed in the elevating type light lighting device according to FIG. 4 FIG. 6 is a configuration diagram of a rotation display unit of the lifting type light lighting device according to FIG. 4 , and FIG. 7 is a configuration cross-sectional view for explaining a second driving unit of the lifting type light lighting device according to FIG. 4 . .

Referring to FIGS. 1 to 7 , the elevating light lighting device 100 of the present invention may further include a rotation display unit 160 installed on one side of the upper body 110 . The rotation display unit 160 may output at least one of preset symbols, characters, and figures as an afterimage pattern by flickering according to rotation of the rotating rod 161 having a plurality of LEDs 161a.

Specifically, the rotation display unit 160 includes a rotation rod 161 , a rotation motor 162 and a second drive unit 163 . The rotation display unit 160 may be accommodated inside the upper body 110 . For example, the rotation display unit 160 is installed to be drawn in and out of the upper body 110 . When the rotation display unit 160 is withdrawn from the upper body 110, it is possible to output at least one of preset symbols, characters, and figures as an afterimage pattern according to rotation.

In addition, the second driving unit 163 may withdraw or retract the rotation display unit 160 from the upper body 110 by the control unit 150 described below. In this case, an opening and closing door 111 may be formed on one side of the upper body 110. The opening and closing door 111 includes a groove 111-2 formed in a long direction along the longitudinal direction and a cover 111-1 to automatically seal the groove 111-2.

For example, the cover 111-1 is slidably installed to seal the groove 111-2 inside the upper body 110. The cover 111-1 may be automatically opened or closed by the control unit 150. Accordingly, the rotation display unit 160 may be drawn out or drawn in from the upper body 110 through the groove 111-2.

More specifically, in the rotating rod 161, a plurality of LEDs 161a are installed at predetermined intervals in the longitudinal direction. A plurality of LEDs 161a installed on the rotating rod 161 are arranged in a preset number. This rotation rod 161 is connected to the rotation motor 162 and is rotated. The rotating rod 161 may output light in a preset flickering pattern through a plurality of LEDs 161a while being rotated by the rotating motor 162 .

In addition, the rotating rod 161 can be made of a synthetic resin material to reduce weight. Preferably, the rotating rod 161 may be folded in a manner in which the plurality of frames 132 are drawn in or drawn out. For example, the rotating rod 161 may be formed as a two-stage or three-stage frame and have a variable length as needed. This rotating rod 161 may also be formed in a folding structure. For example, it is also possible that the plurality of frames 132 are rotated and folded in a hinged structure.

The rotation motor 162 is connected to the rotation rod 161 and rotates at a predetermined speed. The rotation speed of the rotation motor 162 is controlled by the control unit 150 . The rotation motor 162 may rotate the rotation rod 161 in a forward or reverse direction. The rotation motor 162 is positioned to cross one side of the rotation rod 161 and rotates. The rotational speed of the rotational motor 162 may be variably controlled according to vibration while the rotational rod 161 rotates.

In addition, the rotary motor 162 may be accommodated in the cylindrical support 162-1. The support part 162-1 is a housing with a hollow inside and is formed to a predetermined length and is rotatably connected to the second driving part 163. In this case, the second drive unit 163 connects the support unit 162-1 to be rotatable, and rotates the rotation rod 161 to be drawn out from the upper body 110.

The second drive unit 163 draws the rotation display unit 160 out of the upper body 110 or withdraws it from the upper body 110, and operates the second drive motor 163-1 and the rotation bar 163-2. include Specifically, the second drive motor 163-1 is installed on one side of the inside of the upper body 110. Here, the second driving motor 163-1 may be a motor that rotates the rotating rod 161 in forward or reverse rotation. For example, the second drive motor 163-1 is installed on one side of the inner edge of the groove 111-2 formed in the upper body 110. In this case, the rotation bar 163-2 is rotatably connected to the rotation shaft of the second driving motor 163-1.

One side of the rotation bar 163-2 is connected to the rotation shaft of the second driving motor 163-1, and the other side connects to the support unit 162-1 of the rotation display unit 160. The rotation bar 163-2 is rotated forward or backward according to the rotation of the second driving motor 163-1. In this case, the pivoting bar 163-2 is drawn out of the groove 111-2 of the upper body 110 or rotated to be drawn in. The rotation bar 163-2 supports the rotation display unit 160 at a certain angle from the upper body 110.

In addition, the second driving unit 162 may further include an auxiliary link 163-3. The auxiliary link 163-3 may be formed as a two-stage link that is hinged to be folded or unfolded in a folding manner. The auxiliary link 163-3 has one end connected to one side of the pivot bar 163-2 and the other end connected to one side of the upper body 110. When the pivot bar 163-2 is withdrawn from the upper body 110 by the third motor, the auxiliary link 163-3 supports rotation to a certain height.

In addition, it serves to prevent the rotation display unit 160 from being biased to one side due to vibration or impact. Accordingly, the rotation display unit 160 can display afterimage images of various patterns such as symbols, letters, and figures according to various situations occurring on the road, thereby preventing vehicle accidents in advance.

On the other hand, the control unit 150 controls blinking and rotational speed so that symbols, characters, and figures of predetermined afterimage patterns by the plurality of LEDs 161a are output when the rotation rod 161 of the rotation display unit 160 is rotated. In addition, the control unit 150 controls the blinking of the LED of the rotation rod 161 while driving the rotation motor 162 of the rotation display unit 160. The control unit 150 controls the rotational speed and rotational direction of the rotational motor 162 . The control unit 150 may output a triangular afterimage pattern by controlling the flickering pattern of the plurality of LEDs 161a using a Pulse Width Modulation (PWM) method while the rotating rod 161 rotates at a preset speed. In this case, the afterimage pattern of the rotating rod 161 may be output in an arrow or letter shape in addition to a triangular shape.

In addition, the controller 150 may control the second driving unit 163 to withdraw or retract the rotation display unit 160 from the upper body 110 . For example, when the vehicle runs at a speed higher than or lower than a preset speed on the road, the rotation display unit 160 may be pulled out from the upper body 110 to induce a direction to a rear vehicle.

Preferably, the controller 150 can control the upper body 110 to be drawn out when it is deployed from the lower body 120, but can be controlled to be drawn out even when the upper body 110 is coupled to the lower body 120. can In this case, the control unit 150 may control to increase the length of the rotating rod 161 when the upper body 110 rises, and shorten the length of the rotating rod 161 when the upper body 110 descends. You can control it.

Accordingly, the electric signboard is deployed as the warning light rises, and the electric signboard is folded as the warning light descends, thereby controlling the passage of vehicles or pedestrians.

Specifically, the rotation display unit 160 is installed to be drawn out and drawn into the lower part of the upper body 110 . For example, the rotation display unit 160 is pulled out from the lower part of the upper body 110 and rotates between the upper body 110 and the lower body 120, and at least one of symbols, characters, and figures is set as an afterimage pattern. can output

In this case, the display unit 140 may also serve as a light blocking film while the lighting of the LED is released. For example, the display unit 140 may prevent the afterimage light source of the rotation display unit 160 from being scattered during the day or when ambient lighting is bright. Preferably, the rotation display unit 160 may be installed on one side of the upper body 110 to output an afterimage light source toward the front of the vehicle.

However, it is also possible to install the afterimage light source on the other side of the vehicle so as to output the afterimage light source to the rear of the vehicle. For example, the LED of the display unit 140 is turned on at the front of the vehicle to guide traffic conditions to vehicles entering from the front, and the rotation display unit 160 can selectively guide the direction to subsequent vehicles according to the traffic conditions on the road. can

Referring to FIG. 9 , the rotation display unit 160 may be installed on one side of the elevation unit 130 . In this case, the elevating unit 130 may be an elevating unit 130 in which a plurality of frames 132 are connected by a central axis and crossed in an 'X' shape to be folded and driven. In this case, the rotation display unit 160 is installed on the central axis of the plurality of frames 132 . The rotation display unit 160 can be controlled by the control unit 150 to increase the length of the rotating rod 161 when the upper body 110 rises, and when the upper body 110 descends, the length of the rotating rod 161 increases. The length can be controlled to be shortened.

A light blocking film 133 may be further added to the other side of the elevation part 130 . The light blocking film 133 may prevent the afterimage light source of the rotation display unit 160 from being scattered during the day or when ambient lighting is bright. For example, the light blocking film 133 has one side connected to the upper body 110 and the other side connected to the lower body 120. In this case, the light blocking film 133 may be wrinkled so as to be folded or unfolded as the upper body 110 rises or falls. (a) shows a state in which the light blocking film 133 is unfolded as the lifting part 130 ascends, and (b) shows a state in which the light blocking film 133 is folded as the lifting part 130 descends.

Meanwhile, the elevating light illumination device 110 according to an embodiment of the present invention may further include a sensing unit 170 .

The sensing unit 170 is formed on one side of the rotating rod 161 and detects ambient illumination or a distance between one end of the rotating rod 161 and the ground. The sensor 170 outputs illuminance information to the controller 150 according to ambient illuminance. In this case, the control unit 150 may reset the blinking range of the plurality of LEDs 161a according to the illuminance around the rotating rod 161 . For example, power may be saved by driving all of the LEDs of the rotating rod 161 when the illuminance is less than or equal to a preset value, and driving only some LEDs when the illuminance is greater than or equal to a preset value.

In addition, the control unit 150 stops the operation of the rotation motor 162 when the distance between one end of the rotation rod 161 and the ground exceeds the reference distance. This is to prevent the rotating rod 161 from colliding with the ground and being damaged. The control unit 150 may determine whether to rotate by detecting a distance between the rotating rod 161 and the ground before rotating the rotating rod 161 . In this case, the sensing unit 170 may detect the distance between the rotating rod 161 and the ground using a laser sensor. Accordingly, it is possible to improve the effect of focusing attention by displaying an afterimage image as if an image is displayed in the air according to the movement of the rotating display unit 160 in which the afterimage light source is installed.

11 is an exemplary view for explaining a state in which the length of a rotating rod of the rotation display unit according to FIG. 4 is shortened, and FIGS. 11 and 12 are detailed configuration views of the rotation rod of the rotation display unit according to FIG. 4 .

11 and 12, the rotation rod 161 includes a first rod 161-1 and a second rod 161-2. In the present invention, only the first rod 161-1 and the second rod 161-2 are described for convenience of description, but may be formed in multiple numbers according to a user's setting. Preferably, the first rod 161-1 and the second rod 161-2 are connected to each other in multiple stages and accommodated, or are extended in the longitudinal direction.

For example, it may be pulled in or pulled out in an antenna manner. However, it is not limited thereto and may be connected in a folding manner. In this case, the control unit 150 may reset the blinking range of the plurality of LEDs 161a depending on whether the first rod 161-1 and the second rod 161-2 extending in the longitudinal direction exist. In this case, a plurality of LEDs 161a may also be formed on the first rod 161-1 and the second rod 161-2.

In the above, the present invention has been described with reference to the preferred embodiments described with reference to the drawings, but is not limited thereto. Therefore, the present invention should be interpreted by the description of the claims intended to cover obvious modifications that can be derived from the described examples.
