[0039] The rear portion 10 may include a rear body 11 , a first actuator 12 , and a second actuator 13 .

[0040] The rear body 11 may accommodate the rear lamp 100 and the spoiler 200 therein. In other words, the rear lamp 100 may be accommodated in the rear body 11. The rear body 11 facing the direction opposite to the forward direction of the vehicle may be provided with an opening 11a at an outer surface.

[0041] The rear lamp 100 is accommodated in the rear body 11 in a slidably movable manner. Therefore, the rear lamp 100 may be exposed to the outside through the opening 11a in the rear body 11.

[0042] The spoiler 200 may be received behind the opening 11 a formed in the upper surface of the rear body 11. The spoiler 200 may be mounted on the rear lamp 100.

[0049] The lamp body 120 may be accommodated in the lamp housing unit 110. In other words, the lamp body 120 may be movably accommodated in the lamp housing unit 110.

[0050] The lamp housing unit 110 facing the direction opposite to the forward direction of the vehicle may be provided with an opening 110 a on the outer surface. Therefore, the lamp body 120 may be exposed to the outside through the opening 110 a in the lamp housing unit 110 .

[0051] The light source unit 121 may be provided in the lamp body 120. The light source unit 121 may be provided on an end portion of the lamp body 120 facing the direction opposite to the forward direction of the vehicle.

[0055] The control unit 20 may be electrically connected to the first actuator 12 and control the operation of the first actuator 12 to move the tail lamp 100 toward the rear-front direction of the vehicle.

[0056] The control unit 20 may be electrically connected to the second actuator 13 , and may change the tilt angle of the spoiler 200 by controlling the operation of the second actuator 13 so that the spoiler 200 is tilted in the up-and-down direction.

[0057] The control unit 20 may be electrically connected to the light source unit 121, and may control the on and off operation of the light source unit 121. In other words, the control unit 20 may perform control of turning on or off the light source unit 121 according to the driving speed of the vehicle.

[0058] According to the first embodiment of the present disclosure, the operation process of the variable spoiler lighting device for a vehicle configured as above is described as follows.

[0059] refer to Figures 1 to 5 , the control unit 20 may control the operation of the first actuator 12 to insert the rear lamp 100 into the rear body 11 so that the rear lamp 100 does not extend in a direction opposite to the forward direction of the vehicle.

[0060] The spoiler 200 moving together with the rear lamp 100 also does not extend in the direction opposite to the forward direction of the vehicle, and the control unit 20 may control the operation of the second actuator 13 so that the tilt angle of the spoiler 200 is 0 degrees.

[0061] At this time, the control unit 20 may perform a turn-off control on the light source unit 121 to turn off the light source unit 121 , or may perform a turn-on control on the light source unit 121 to turn on the light source unit 121 .

[0062] refer to Figure 2 and Figure 5 When the vehicle is traveling at a high speed of about 100 km / h to about 130 km / h, the control unit 20 can control the operation of the first actuator 12 so that the lamp body 120 inserted into the lamp housing unit 110 is exposed from the rear of the rear body 11 and extends in a direction opposite to the forward direction of the vehicle.

[0063] The spoiler 200 moving together with the rear lamp 100 also extends together with the lamp body 120 in a direction opposite to the forward direction of the vehicle, and the control unit 20 can control the operation of the second actuator 13 so that the spoiler 200 continues to maintain its tilt angle of 0 degrees.

[0064] The movement of the lamp body 120 can achieve the dual effects of improving aerodynamic performance and ensuring safe driving when the vehicle is traveling at high speed.

[0065] At this time, the control unit 20 may perform turn-off control of the light source unit 121 to turn off the light source unit 121 , or may perform turn-on control of the light source unit 121 to turn on the light source unit 121 .

[0066] refer to Figure 3 and Figure 5When the vehicle is traveling at a constant speed of about 70 km / h or about 100 km / h, the control unit 20 can control the operation of the first actuator 12 so that the lamp housing unit 110 inserted into the rear body 11 is exposed to the outside from the rear of the rear body 11 and extends together with the lamp body 120 in a direction opposite to the forward direction of the vehicle.

[0067] The spoiler 200 moving together with the rear lamp 100 also extends together with the lamp housing unit 110 and the lamp body 120 in a direction opposite to the forward direction of the vehicle, and the control unit 20 can control the operation of the second actuator 13 so that the spoiler 200 continues to maintain its tilt angle of 0 degrees.

[0068] When the vehicle travels at a constant speed, the movement of the lamp housing unit 110 and the lamp body 120 may redirect the flow of the vortex formed behind the vehicle, allowing the vehicle to travel a greater distance.

[0069] At this time, the control unit 20 may perform turn-off control of the light source unit 121 to turn off the light source unit 121 , or may perform turn-on control of the light source unit 121 to turn on the light source unit 121 .

[0070] refer to Figure 4 and Figure 5 When the vehicle is traveling at a speed of about 130 km / h or more, or in bad weather, the control unit 20 may control the operation of the first actuator 12 so that the lamp body 120 inserted into the lamp housing unit 110 is exposed to the outside from the rear of the rear body 11 and extends in a direction opposite to the forward direction of the vehicle. In addition, the control unit 20 may control the operation of the second actuator 13 so that the spoiler 200 has an inclination angle of about 40 degrees to about 90 degrees.

[0071] When the vehicle is traveling at high speed or in extremely bad weather, the tilting operation of the spoiler 200 can redirect the flow of airflow in a downward direction, thereby enhancing the grip of the tire on the road, improving stability when traveling forward, and contributing to safe driving.

[0072] At this time, the control unit 20 may perform turn-off control of the light source unit 121 to turn off the light source unit 121 , or may perform turn-on control of the light source unit 121 to turn on the light source unit 121 .

[0087] refer to Figure 6 and Fig. 9 As an implementation example, when the vehicle is traveling below a first preset speed, the control unit 40 may control the operation of the first actuator 32 so that the first spoiler 410 and the second spoiler 420 are inserted into the rear body 31, and the first spoiler 410 and the second spoiler 420 therefore do not extend in a direction opposite to the forward direction of the vehicle.

[0088] As another implementation example, using a control signal generated in the vehicle's electronic control unit (ECU) according to the vehicle's driving mode selected by the occupant's manual operation, the control unit 40 can control the operation of the first actuator 32 so that the first spoiler 410 and the second spoiler 420 housed in the rear body 31 do not extend in a direction opposite to the forward direction of the vehicle.

[0089] refer to Figure 7 and Fig. 9As an implementation example, when the vehicle is traveling above a first preset speed but below a second preset speed, the control unit 40 may control the operation of the first actuator 32 so that the first spoiler 410 and the second spoiler 420 inserted into the rear body 31 are exposed to the outside from behind the rear body 31 and thus extend in a direction opposite to the forward direction of the vehicle.

[0090] As another implementation example, using a control signal generated in the vehicle's ECU according to the vehicle's driving mode selected by the occupant's manual operation, the control unit 40 can control the operation of the first actuator 32 so that the first spoiler 410 and the second spoiler 420 housed in the rear body 31 are exposed to the outside from the rear of the rear body 31 and thus extend in a direction opposite to the forward direction of the vehicle.

[0091] When the vehicle is traveling, the movement of the first spoiler 410 and the second spoiler 420 may redirect the flow of airflow formed behind the vehicle, allowing the vehicle to travel a greater distance.

[0092] refer to Figure 8 and Fig. 9 As an implementation example, when the vehicle is traveling at a second preset speed or higher than the second preset speed, or traveling in bad weather, the control unit 40 may control the operation of the second actuator 33 so that the inclination angle of the first spoiler 410 is greater than about 0 degrees.
