Furthermore, the plurality of light emitting parts 120 may be disposed to be spaced apart from each other in the front and rear direction of the vehicle such that adjacent light emitting parts 120 have a predetermined area. This is to prevent the generation of the shaded area where the light is not irradiated when observed from just before the running direction of the vehicle body 1.

Here, in order to prevent confusion, the description is limited to the case provided in the front left portion of the vehicle body 1 of the head lamp module, but the principle of arranging the plurality of light emitting units 120 of the head lamp module ( It will be obvious that the same may be applied to the case provided in the front right part of 1) and the case provided in the rear end left part and the right part of the vehicle body 1 of the rear lamp module.

Each of the plurality of light emitting parts 120 described above includes at least two light emitting surfaces (horizontal light emitting surface 121 and an upward light emitting surface) which will be described later so that light is divided into at least two directions by the bending surface 122 described above. (123)).

As described above, the bending surface 122 may be formed along the line of the lower end 107 of the lamp housing 110.

More specifically, the lamp housing 110, the upper end 105 is formed to be inclined upward toward the outside of the vehicle body, the lower end 107 is started at one end of the upper end 105 of the lamp housing 110 described above and the upper end ( In addition to the other end of 105 may be formed to be inclined downward to the outside of the vehicle body to be inclined upwardly rounded.

As described above, the top 105 and bottom 107 lines of the lamp housing 110 are continuously provided with the

design lines

In a preferred embodiment of the lamp device 100 of the vehicle according to the present invention, the light emitting unit 120, as described above, may be provided with F-OLED. F-OLED, as the name suggests, adopts an organic light emitting diode (OLED) light emitting surface, and refers to a flexible shape that can be bent to one side or the other side.

In particular, the light emitting unit 120 may be employed as a printing type OLED (P-OLED, Plastic Organic Light Emitting Diode) (hereinafter, referred to as 'P-OLED') among various kinds of F-OLED. Since P-OLED adopts DC driving method, it does not need an inverter, so there is no noise during driving, and it has high brightness (250cd / m2 or more) and long life (more than 10,000 hours) characteristics but ITO film like inorganic EL Since it is used as a flim, it has the advantage of being able to be banded.

In addition, the P-OLED can freely change and control the entire illuminance, and can also partially change the illuminance on one light emitting surface, and the color can also be colorfully changed in whole or in part.

The light emitting unit 120 divided by the bending surface 122 is a horizontal light emitting surface 121 bent to irradiate horizontally with respect to a horizontal driving direction of the vehicle, and a band that is radiated upward from the horizontal light emitting surface 121. An upward emitting surface 123.

Here, the horizontal light emitting surface 121 is a premise that the vehicle is formed to have a first inclination to be lowered with respect to the horizontal plane in the forward or downward direction when the ground on which the wheel touches the horizontal plane, the upward light emitting surface 123 is the first It is formed to have a second inclination smaller than the inclination, the horizontal light emitting surface 121 and the upward light emitting surface 123 may form an obtuse angle with each other.

As described above, each of the plurality of light emitting parts 120 includes a horizontal light emitting surface 121 and an upward light emitting surface 123, and the horizontal light emitting surface 121 and the upward light emitting surface of each light emitting part 120 ( The obtuse angle formed by 123 may be set differently.

This will be described later, but the angle formed by the horizontal light emitting surface 121 and the upward light emitting surface 123 are set differently as follows. That is, the lamp device of the vehicle needs to be set at an angle that is appropriate for the high beam irradiation mode and the low beam irradiation mode among various light distribution patterns, as well as the one turn direction irradiation mode, the other turn direction irradiation mode, and the turn signal among the various light distribution patterns. It is necessary to set the proper angle required for the lamp irradiation mode and the compound irradiation mode in which each of the various light distribution patterns is applied in combination. Therefore, in a preferred embodiment of the lamp device 100 of the vehicle according to the present invention, the angle between the horizontal light emitting surface 121 and the upward light emitting surface 123 is set differently in consideration of each light distribution pattern in advance. In addition, it is necessary to be able to complete only the control of the whole or partial illuminance, the whole or partial color of the light emitting unit 120 necessary for implementing each light distribution pattern.

The plurality of light emitting parts 120 may be bent to have horizontal light emitting surfaces 121 and upward light emitting surfaces 123 having different angles with respect to the bending surfaces 122. Here, when the plurality of light emitters 120 each have a light emitting surface having the same area, the areas of the horizontal light emitting surface 121 and the upward light emitting surface 123 of each of the plurality of light emitting units 120 are bent. The area may be set differently toward one side or the other side along the surface 122.

As described above, since the bending surface 122 is provided correspondingly along the lower end 107 of the lamp housing 110 provided continuously on the

design lines

10 and 20 of the vehicle body 1, each light emitting part is provided. Naturally, the areas of the horizontal emitting surface 121 and the upward emitting surface 123 of 120 may be set differently depending on the bending surface 122.

Although the bending surface 122 serves as a reference for distinguishing the horizontal light emitting surface 121 and the upward light emitting surface 123 from the functional observation, the bending surface 122 also constitutes a P-OLED. It is natural that light can be irradiated in the area of 122), and the color can be changed in whole or in part.

FIG. 9 is a front view illustrating a 'turn signal lamp irradiation mode' among various light distribution patterns, and FIG. 9 is a conceptual view illustrating a control relationship between the bracket and the light emitting unit during the 'incline driving irradiation mode' among various light distribution patterns.

As illustrated in FIG. 7, the plurality of light emitting parts 120 include a power input terminal (not shown) provided at any one of an upper end and a lower end of an upward light emitting surface 123, and a horizontal light emitting surface 121. It may further include a power output terminal (not shown) provided in the other part of the top and bottom of the.

The plurality of light emitting units 120 may form a serration shape in which adjacent lower light emitting units 120 are alternately arranged with lower ends formed in a straight line of the horizontal light emitting surface 121.

When the ends of the plurality of light emitting parts 120 form a serration shape, when the light is irradiated through the entire light emitting part 120, the serration shape is projected along the bending surface 122. The configuration of the light emitting unit 120 of a preferred embodiment of the lamp device 100 of the vehicle according to the invention makes it possible to feel intuitively.

In particular, the above-mentioned serration shape may play a role of enabling the driver of the rear driving vehicle following from behind to recognize the correct direction when implementing the turn signal lamp irradiation mode to be described later.

On the other hand, the front end of the upward light emitting surface 123 formed in a straight line of the plurality of light emitting portion 120, the curve of the upper end 105 of the lamp housing 110 (that is, the design line 10 formed in the appearance of the vehicle body 1) And a predetermined curve spaced apart from the lower portion by a predetermined distance from the curved line continuously connected to (20), and the front end of the horizontal light emitting surface 121 formed in a straight line of the plurality of light emitting parts 120 is a lamp housing. A predetermined curve may be formed to be spaced apart from the curve of the lower end 107 of the 110 by a predetermined distance.

Of course, only the combination of the top (end) of the upward emitting surface 123 and the horizontal emitting surface 121 forms a predetermined curve, and as described above, the ends of the upward emitting surface 123 and the horizontal emitting surface 121 are formed. It is preferable to maintain a linear shape to have a serration shape.

Meanwhile, as illustrated in FIG. 6, the plurality of light emitting parts 120 may be disposed to be spaced apart from each other in the front and rear direction of the vehicle such that adjacent light emitting parts 120 overlap a predetermined area. As described above, this is due to the fact that the light emitting surface of the light emitting part 120 is designed to face forward or side while being arranged to be bent toward the outside from the center of the vehicle body 1.

The plurality of light emitting parts 120 are provided with overlapping predetermined areas between adjacent light emitting parts 120. As described above, when the plurality of light emitting parts 120 are observed in front of a driving direction of the vehicle, a shaded area is provided. Can block the occurrence of However, the plurality of light emitting parts 120 are arranged to be bent toward the outside of the vehicle body 1 in the lamp housing 110, as shown in FIG. 6, when the observer observes from one side of the vehicle, the front and rear Shaded zones can be generated through the spaces.

Therefore, in a preferred embodiment of the lamp device 100 of the vehicle according to the present invention, the plurality of light emitting units 120 irradiates light while filling the spaced apart portions of the adjacent light emitting units 120 in the front-back direction. It may further comprise an additional banding portion banded to be.

The additional banding part is provided in a portion where adjacent light emitting parts 120 overlap each other, so that the shadow area is not generated while the light is being irradiated at any position by the observer by filling the spaced parts in the front and rear directions. Play a role.

The additional banding part may be formed by bending the end of the existing light emitting part 120, and a separate P-OLED may be separately attached.

Here, the main bracket 170 fixes the plurality of unit brackets 130 on the front surface, and fixes the printed circuit board 180 electrically connected to the plurality of unit brackets 130 on the rear surface.

Each of the plurality of light emitting units 120 is attached to each of the plurality of unit brackets 130, so that the angles formed by the upwardly emitting surface 123 and the horizontally emitting surface 121 are different from each other.

That is, the plurality of light emitting parts 120 are formed of an upward light emitting surface 123, a horizontal light emitting surface 121, and a bending surface 122 separating the same, and thus, the plurality of unit brackets 130 are also illustrated in FIG. 8.

However, despite the name, the transparent outer lens 140 may be made of a transparent material projected from the outside to the inside, and of course, made of an opaque material to diffuse or disperse light emitted from a relatively high P-OLED. Of course it can.

In the present invention, the meaning of the transparent outer lens 140 does not indicate whether the material is transparent or opaque, but a plurality of light emitting parts 120 are disposed in the lamp housing 110, but the relationship with the transparent outer lens 140. What is the placement relationship in?

As illustrated in FIG. 6, the plurality of light emitting parts 120 may be disposed such that the curved surface of the bending surface 122 is spaced apart from the inner surface of the transparent outer lens 140.

The implementation of various light distribution patterns of the lamp device 100 of the vehicle according to the present invention configured as described above will be described briefly as follows.

However, for convenience of understanding, it will be described by dividing into a case of driving by a head lamp module and a case of driving by a rear lamp module.

First, assuming that the case is driven by the headlamp module, among the various light distribution patterns, the driving direction irradiation mode for irradiating light in the direction in which the vehicle travels in a straight traveling lane, and the direction in which the vehicle turns to one side or the other side One-turn direction irradiation mode, the other-turn direction irradiation mode, which illuminates the light, and 'turn signal lamp irradiation mode', which illuminates the light to indicate the turning direction when the vehicle turns to one or the other side, and It may be implemented as a 'low beam irradiation mode' for irradiating light downward in the direction of the ground on which the vehicle travels, and a 'high beam irradiation mode' for irradiating light upward above the ground on which the vehicle travels.

Next, assuming that the vehicle is driven by the rear lamp module, the rear driving irradiation mode, in which the vehicle travels in the rear straight direction among various light distribution patterns, and which follows when the vehicle turns to one side or the other side when driving ahead 'Turn signal lamp irradiation mode' to illuminate the driver to blink the light to indicate the turning direction to the driver of the vehicle, 'brake investigation mode' to warn the driver of the following vehicle when the driver presses the brake; It can be implemented as a 'brake brake investigation mode' that warns the driver of the following vehicle when operating with abnormal power.

First, when the light distribution pattern of the head lamp module is implemented, the specific operation of the lamp device 100 of the vehicle according to the present invention will be described as follows.

Light required in the low beam irradiation mode in which light is radiated downward toward the ground in which the vehicle travels is a horizontal light emitting surface among the upward light emitting surface 123 and the horizontal light emitting surface 121 of the light emitting units 120. It is preferable to adopt the light of 121).

Therefore, in the low beam irradiation mode, the controller may control the illuminance of the light emitted from the horizontal light emitting surface 121 to be greater than the illuminance of the light emitted from the upward light emitting surface 123.

On the contrary, the light required in the high beam irradiation mode in which light is radiated upward from the ground on which the vehicle travels is upwardly emitted from the upward light emitting surface 123 and the horizontal light emitting surface 121 of the plurality of light emitting units 120. It is preferable to be adopted as the light of the face (123).

Therefore, in the high beam irradiation mode, the controller may control the illuminance of the light emitted from the upward emitting surface 123 to be greater than the illuminance of the light emitted from the horizontal emitting surface 121.

Light required in the driving direction irradiation mode in which the vehicle irradiates light in the direction of driving the straight driving lane includes light emitting units positioned near the center of the vehicle body 1 among the plurality of light emitting units 120. When light emitted from 120 is more advantageous, and the low beam irradiation mode is applied in combination, the light emitted from the horizontal light emitting surface 121 of the upward light emitting surface 123 and the horizontal light emitting surface 121 of the light emitting unit 120 may be irradiated. When the light is more advantageous, and the high beam irradiation mode is applied in combination, the light emitted from the upward emitting surface 123 of the upward emitting surface 123 and the horizontal emitting surface 121 of the light emitting unit 120 may act more advantageously. Can be.

Therefore, in the traveling direction irradiation mode, the control unit controls the light of the light emitting unit 120 positioned near the outside of the vehicle body 1 to the illuminance of the light emitted from the light emitting unit 120 located near the center of the vehicle body 1. It is preferable to control the irradiance to be larger than the illuminance of and to control the illuminance of the upward emitting surface 123 and the horizontal emitting surface 121 according to the light distribution pattern applied in combination.

Next, the light required in the one turn direction irradiation mode and the other turn direction irradiation mode for irradiating light in the direction in which the vehicle turns to one side or the other side is provided in the lamp housing 110 at the turn direction side. While the light emitted from the light emitting unit 120 located closer to the outside of the vehicle body 1 among the plurality of light emitting units 120 is more advantageous, the plurality of light emitting units provided in the lamp housing 110 opposite to the turning direction side The light emitted from the light emitting unit 120 located near the center of the center of the vehicle body 1 of the unit 120 is more advantageous. Meanwhile, light emitted from the horizontal light emitting surface 121 of the upward light emitting surface 123 and the horizontal light emitting surface 121 of the light emitting unit 120 may act more advantageously. Similarly, when the low beam irradiation mode is applied in combination, light emitted from the horizontal light emitting surface 121 of the upward light emitting surface 123 and the horizontal light emitting surface 121 of the light emitting unit 120 is more advantageous, and the high beam irradiation mode is more advantageous. When a combination is applied, the light emitted from the upward emitting surface 123 of the upward emitting surface 123 and the horizontal emitting surface 121 of the light emitting unit 120 may act more advantageously.

Therefore, in one side turning direction irradiation mode and the other side turning direction irradiation mode, the control unit, the illuminance of the light emitting parts 120 located close to the direction of the vehicle turning direction of the light emitting parts 120 located close to the opposite direction side It is necessary to control the light to be irradiated with greater illuminance than illuminance, and when a low beam irradiation mode or a high beam irradiation mode is applied in combination, appropriate control is required for each light distribution pattern.

On the other hand, when the vehicle irradiates light in the above-described turning direction irradiation mode, light required in the turn signal lamp irradiation mode in which the light is blinked and irradiated so as to display the turning direction in conjunction with the operation of the turn signal lever is a vehicle body. Among the lamp housings 110 provided at the front left and right sides of (1), it is limited to the light irradiated from the light emitting part 120 provided in the rotation direction side lamp housing 110, In particular, the rotation direction side lamp housing 110 The light emitted from the light emitting unit 120 disposed closer to the outside of the vehicle body 1 of the light emitting unit 120 may act more advantageously.

However, when one turn direction irradiation mode or the other turn direction irradiation mode and the above-described turn signal lamp irradiation mode are applied in combination at the same time, the turn signal using the upward emitting surface 123 of the emitting surface of the light emitting unit 120 is used. It is preferable to implement the lamp irradiation mode, and to implement the one side turning direction irradiation mode or the other side turning direction irradiation mode using the horizontal light emitting surface 121 of the light emitting unit 120.

In this case, the controller may control the light to be irradiated by changing the color of the recognition rate so that the driver of the surrounding vehicle can recognize it more clearly.

When implementing the light distribution pattern of the rear lamp module, the specific operation of the lamp device 100 of the vehicle according to the present invention will be described.

The light required in the rear driving irradiation mode in which the vehicle travels in the rear straight direction can illuminate the entire left and right rear surface of the vehicle body 1 so that the driver can easily observe the rear side through the side mirrors provided on the left and right sides of the vehicle. Can be set to light. Accordingly, all of the light emitting parts 120 provided in the lamp housing 110 provided at the rear left and right sides of the vehicle body 1 are set to advantageous light, but preferably the upward light emitting surface 123 and the horizontal of the light emitting part 120 are horizontal. The light emitted from the horizontal light emitting surface 121 of the light emitting surface 121 may act as more advantageous light.

Therefore, in the backward driving irradiation mode, the control unit controls to irradiate light with the same illuminance regardless of the position of the light emitting unit 120 in the lamp housing 110, but the light emitted from the horizontal light emitting unit 120 The illuminance may be controlled to be greater than the illuminance of the light emitted from the upward emitting surface 123. However, more preferably, the illuminance of the light emitting portion 120 disposed to be spaced apart from the center portion of the vehicle body 1 is greater than the illuminance of the light emitting portion 120 disposed close to the center portion of the vehicle body 1. Can be controlled. This is to allow the driver to more clearly observe the rear side of the vehicle body 1 through the side mirror as described above.

When the vehicle travels forward, when the headlamp module implements the light distribution pattern in the one-turn direction irradiation mode or the other-turn direction irradiation mode as described above, the rear lamp module also flashes the light to indicate the turning direction to the driver of the following vehicle. The light distribution pattern of the turn signal lamp irradiation mode may be implemented.

The light required in the turn signal lamp irradiation mode of the rear lamp module is to enable the drivers of all following vehicles to know the turning direction of the driving vehicle more clearly in advance. The light emitted from the lamp housing 110 provided on the side of the pivot direction is advantageous, and the light emitting part 120 disposed near the outside of the vehicle body 1 among the plurality of light emitting parts 120 in the lamp housing 110. The light irradiated from each other is more advantageous, and the light irradiated from the horizontal light emitting surface 121 of the upward light emitting surface 123 and the horizontal light emitting surface 121 of the light emitting unit 120 may act more advantageously.

In particular, in a preferred embodiment of the vehicle lamp device 100 according to the present invention, the control unit, when the driver operates the turn signal lever (not shown) provided in the vehicle, the lamp for the turn signal provided in the operation direction In addition to the flashing control, the plurality of light emitting units 120 may be sequentially flashed in the operation direction of the turn signal lever. In this case, since the plurality of light emitting parts 120 are sequentially flashed toward the turning direction of the vehicle, the plurality of light emitting parts 120 are blinked to have a predetermined direction toward the turning direction, so that drivers of the following vehicle more accurately predict the turning direction and threaten a safety accident of the vehicle. This has the advantage of being prevented in advance and at the same time enables three-dimensional investigation.

In addition, it is natural that the controller may control the irradiation of the plurality of light emitting parts 120 by changing the color from the first color to the second color. The second color may be a color having a better recognition rate than the second color.

On the other hand, the light required in the brake irradiation mode, which warns the driver of the following vehicle when the vehicle driver brakes, is advantageous in that light emitted from all of the lamp housings 110 provided at the rear left and right sides of the vehicle body 1 is advantageous. In particular, the light emitting unit 120 positioned closer to the outside of the vehicle body 1 than the light emitted from the light emitting unit 120 positioned closer to the center of the center of the vehicle body 1 of the light emitting units 120 of the lamp housing 110. The light irradiated from) is more advantageous.

Therefore, in the brake irradiation mode, the control unit may be configured from the light emitting unit 120 located near the outside of the vehicle body 1 among the plurality of light emitting units 120 in the lamp housing 110 provided at the rear left and right sides of the vehicle body 1. The illuminance of the irradiated light may be controlled to be irradiated larger than the light irradiated from the light emitter 120 positioned near the center of the vehicle body 1.

In addition, as described above, in order that the drivers of the following vehicles may recognize the brake operation of the driving vehicle more clearly, the color of light emitted from the light emitting unit 120 may be controlled to be irradiated by changing the color of the light having a good recognition rate. have.

In this case, the controller may control the illuminance of the horizontal light emitting surface 121 to be greater than the illuminance of the upward light emitting surface 123 so as not to disturb the driver's forward driving view of the following vehicle.

Next, the light required in the rapid brake irradiation mode, which warns the driver of the vehicle following when the vehicle driver operates the brake at a predetermined or higher power, is the same as in the brake irradiation mode.

Therefore, in the sudden brake irradiation mode, the control unit may control the same as in the brake irradiation mode, but may control the plurality of light emitting units 120 to blink at predetermined time intervals.

In addition, since the light distribution pattern of the rapid brake irradiation mode should be more clearly recognized by the drivers of the following vehicle, the illuminance of the light emitted from the upward emitting surface 123 of the emitting surface of the light emitting unit 120 is the horizontal emitting surface. It is preferable to control so as to be irradiated larger than the illuminance of the light irradiated from 121.

The brake irradiation mode and the rapid brake irradiation mode of the rear lamp module described above describe the control of the light emitting unit 120 by the control unit during normal driving at night, but may be controlled differently as described below during the daytime driving.

That is, a preferred embodiment of the lamp device 100 of the vehicle according to the present invention may further include a natural light determination unit for determining the position of the sun through the GPS or body behavior detection unit.

The natural light determination unit acquires the macroscopic solar position information through GPS as described above, and acquires the microscopic solar position information according to the movement of the vehicle body 1 through the vehicle body motion detection unit. The controller is configured to calculate the optimum illuminance of the light emitting surface in relation to the vehicle.

That is, the controller controls the illuminance of the horizontal light emitting surface 121 differently for each position of the sun detected by the natural light determination unit, so that the driver of the following vehicle misses an appropriate warning while looking at the sun during the daytime driving. To prevent it.

In the above, the typical light distribution pattern of the head lamp module and the rear lamp module has been described in detail through a preferred embodiment of the lamp device 100 of the vehicle according to the present invention.

However, the light distribution pattern to which the preferred embodiment of the lamp device 100 of the vehicle according to the present invention is applied is not limited to the above-described example.

For example, referring to FIG. 9, when the driving vehicle enters an uphill slope and reaches an uphill end point, the driving vehicle travels downhill slope again to reach an end slope of the downhill slope and eventually runs on flat ground, and three driving units 40 for each starting point are provided. And illumination control of the light emitting unit 120 is made differently. This control is referred to as the "running road irradiation mode".

First, when the driving vehicle travels uphill, the driver may not be able to secure a driving field in front of the ramp in front of the ramp when the vehicle enters the uphill ramp in a general driving direction irradiation mode among various light distribution modes.

Therefore, when the front road condition of the driving vehicle sensed by the vehicle body motion detection unit is detected as the entrance of the uphill slope, the control unit may temporarily implement the high beam irradiation mode until the driving vehicle completely enters the uphill slope. Control 120. The high beam irradiation mode of the light emitting unit 120 controlled by the control unit has been described in detail above.

Next, when the driving vehicle is switched at the end of the uphill slope and starts driving downhill, the driver may move to the downhill slope when the vehicle is driven downhill in the normal driving direction irradiation mode among various light distribution modes. There is a problem that can not secure the driving field of the downward.

Therefore, when the front road condition of the traveling vehicle sensed by the body behavior detection unit is detected as the end point of the uphill slope and the start point of the downhill slope, the control unit temporarily irradiates the low beam until the traveling vehicle completely enters the downhill slope. The light emitter 120 may be controlled to implement the mode. Similarly, the control regarding the low beam irradiation mode of the light emitting unit 120 controlled by the controller has been described above.

Lastly, when the driving vehicle travels on the flat at the end of the downhill slope, if the driving vehicle enters the flat in the general driving direction irradiation mode among the various light distribution modes, the driver cannot secure the driving field in front of the flat at the entry point. There is a problem.

Therefore, when the front road condition of the traveling vehicle sensed by the vehicle body motion detection unit is detected as the end point of the downhill slope, the control unit temporarily moves the light emitting unit 120 until the driving vehicle completely enters the flat surface. Can be controlled to be implemented.

On the other hand, although not shown in the drawings, in general, when the vehicle is traveling on the unpaved road surface, when the attitude of the vehicle is severely fluctuated from side to side due to the uneven road surface, the light irradiated from the headlamp device 100 also the vehicle body (1) There is a problem that swings left and right along).

In a preferred embodiment of the vehicle lamp device 100 according to the present invention, when the vehicle body motion detection unit detects that the inclination toward one side or the other side of the traveling vehicle, the controller is irradiated from the light emitting surface of the light emitting unit 120 The illumination of the upward emitting surface 123 and the horizontal emitting surface 121 may be controlled so that the light is irradiated to the same target point as the light emitted when the inclination of the driving vehicle is '0' by the body behavior detecting unit.

As such, the control unit controls the illuminance of the light emitting unit 120 so that the light emitted from the light emitting unit 120 is continuously irradiated to a predetermined target point despite the left and right fluctuations of the vehicle body 1 and the target. By illuminating the illumination to the point most brightly, there is an advantage in that the driver does not miss the driving visual field caused by the swing of the vehicle body 1 to prevent a safety accident.

According to a preferred embodiment of the lamp device 100 of the vehicle according to the present invention having such a configuration, a plurality of light emitting unit 120 and the upward light emitting surface 123 and the horizontal light emitting surface ( By appropriately controlling the illuminance of 121), it is possible to implement various light distribution patterns, as well as to have a three-dimensional light distribution pattern.

In the above, various embodiments of a lamp device of a vehicle according to the present invention have been described in detail with reference to the accompanying drawings. However, the embodiment of the present invention is not necessarily limited to the above-described preferred embodiment, and it is natural that various modifications and equivalents can be made by those skilled in the art to which the present invention pertains. something to do. Therefore, the true scope of the present invention will be defined by the claims to be described later.
