[0040] Hereinafter, a dynamic light device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0041] The dynamic light device 10 according to the embodiment of the present invention is implemented as an ambient light that is arranged in the interior space of a vehicle to create emotions in the interior space of the vehicle.

[0042] The dynamic lamp device 10 of the present invention performs a predetermined dynamic lighting function which continuously changes the output signal for visual recognition so that in addition to the static lighting function of outputting simple light in a fixed state, dynamic changes in the lighting state can be visually recognized while minimizing the number of light sources implemented as LEDs.

[0043] like Figures 1 to 4 As shown, the dynamic light device 10 includes a housing 100, a substrate unit 200, and a lamp unit 300. The housing 100 is fixedly mounted to the interior of a predetermined vehicle door (VD). The housing 100 includes a housing body 110 and a housing base 120. The housing base 120 is fixedly mounted to the inner side of the interior of the vehicle door, and the housing body 110 is engaged with the housing base 120 to provide an internal space between the housing base 120 and the housing body 110 when assembled, thereby fixing the positions of other components.

[0044] The case body 110 is exposed to the outside of the interior trim of the vehicle door. The case body 110 includes a body through hole 111 formed therein to allow the light indicator cover 310 of the lamp unit 300 to be inserted therein. Therefore, light emitted from the light source unit 330 disposed in the case body 110 and emitted from the light transmission unit 320 can be emitted to the outside through the light indicator cover 310.

[0045] In this embodiment of the present invention, the housing 100 includes a housing connector 130. The housing connector 130 enables internal arrangement of the substrate unit 200 on which the lamp light source unit 330 implemented as an LED is arranged. The housing connector 130 may include a terminal for electrical connection with an external power source.

[0046] As described above, the lamp light source unit 330 of the lamp unit 300 is provided on the substrate unit 200. In addition, a power supply terminal is also provided on the substrate unit 200, so that power can be provided to the control unit 20 connected to the lamp light source unit 330 and the substrate unit 200 through electrical connection with an external power source, and to the storage unit 30 and the operation unit 40 connected to the control unit 20.

[0047] The light unit 300 is at least partially connected to the base unit 200 and allows light emitted from the light unit 300 to escape from the housing 100 toward the outside of the housing. The light unit 300 includes one or more light transmission units 320 and light source units 330, as described above.

[0048] The light transmission unit 320 is provided in a single number or a plurality of numbers. Although in the present embodiment, the light transmission unit 320 is mainly described as a structure provided in a single number and formed in a linear or curved shape, the light transmission unit 320 may be modified in various ways, such as a structure having a plurality of light transmission units 320 overlapped or branched.

[0049] The light transmission unit 320 is disposed in the housing 100, more specifically, in the internal space defined between the housing body 110 and the housing base 120. The light transmission unit 320 has a predetermined length. The light transmission unit 320 is made of a light-conducting material. The light source unit 330 is disposed at at least both ends of the light transmission unit 320. In this embodiment, the light transmission unit 320 adopts a simple straight line or curved line shape, and the light source unit 330 (330L, 330R) is disposed at each of the two ends of the light transmission unit 320.

[0050] Although the light source unit 330 is implemented as an LED in this embodiment, it can be selected in various ways within the range of adopting a configuration having a light emitting capability. The light source unit 330 is provided at each of both ends of at least one light transmitting unit 320. As described above, in the present embodiment, the light transmitting unit 320 adopts a simple straight line or curved line shape, and the light source unit 330 is provided at each of both ends of the light transmitting unit 320. The light source unit 330 may include a separate component element for preventing light from leaking to the periphery thereof.

[0051] The light emitted from the light source unit 330 is incident into the light transmitting unit 320 through both ends of the light transmitting unit 320 , and then is emitted to the outside through the main body through hole 111 of the housing 100 .

[0052] The light source units 330 disposed at both ends of the light transmission unit 320 are controlled in a separate and independent manner, so that the light incident to both ends of the light transmission unit 320 according to the control of the separate output signals from the light source units 330 can be combined in the light transmission unit 320. And the color or intensity of the light combined according to the control and change of the output signal from the light source unit 330 can perform a dynamic lighting function, which changes along the length of the light transmission unit 320.

[0053] In other words, the dynamic light device 10 of the present invention further includes a control unit 20. The control unit 20 can apply a light source control signal to each light source unit 330 disposed at both ends of the light transmission unit 320 to change the intensity or color of light along the length of the light transmission unit 320, so that a predetermined intensity or color area with a predetermined light intensity or color is transformed along the length of the light transmission unit 320.

[0054] The characteristics of light, i.e., the intensity of light output from the light source unit 330 in response to a light source control signal applied from the control unit 20 to the light source unit 330, and then transmitted through the light transmission unit 320 and output from the light transmission unit 320, changes relative to multiple regions along the length of the light transmission unit 320.

[0055] The control unit 20 is connected to the storage unit 30 and the operation unit 40. The control unit 20 applies a storage control signal to the storage unit 30 and applies an operation control signal to the operation unit 40. The storage unit 30 has preset data stored therein. The preset data contains information on the size of an electrical signal (e.g., a voltage or current of the lamp light source unit 330) required to perform an operation mode (i.e., a dynamic mode and a static mode to be described later). PWM control is performed in the lamp light source unit 330, and a detailed description thereof is omitted.

[0056] As described above, the control unit 20 applies the light source control signal to the lamp light source unit 330 to control the intensity of the light output from the lamp light source unit 330 to change relative to the plurality of regions along the length of the lamp light transmission unit 320. When outputting light stored in the storage unit 30, the preset data stored in the storage unit 30 includes data on the intensity of the light formed relative to the plurality of regions divided along the length of the lamp light transmission unit 320 as described above.

[0057] Such data may be converted in the form of a certain function and stored in the storage unit 30, and stored as point data of light intensity for the length of the light transmission unit 320. The control unit 20 applies the operation control signal to the operation unit 40 based on the preset data, so that the operation unit 40 can calculate the input value of the light source unit 330 to output light with a desired intensity at a relevant time point in a relevant area, thereby realizing the operation mode, (i.e., the dynamic mode selected by the user through functional operation, interpolation or extrapolation), and the control unit 20 generates a light source control signal corresponding to the input value applied to the light source unit 330.

[0058] In other words, Figure 5 As shown, the light source units 330 (330L and 330R) are respectively arranged at both ends of the right side and the left side of the light transmission unit 320. When the light source units 330 (330L, 330R) arranged at both ends of the light transmission unit 320 are in the ON (lit) state, a graph of the light output intensity (i.e., light intensity) transmitted to and output from the light transmission unit 320 from each of the light source units 330 (330L and 330R) along the length of the light transmission unit 320 is shown. That is, in the case where the length of the light transmission unit 320 is divided into three areas ①, ②, and ③, Figure 5The figure shows a shape in which the light output intensity decreases in opposite directions from both ends of the light transmission unit 320, in which the light source units 330 (330L and 330R) implemented as LEDs are provided. In other words, Figure 5 The graph shows the following shape, wherein when the left light source unit 330L is assumed as a reference, the change in light output intensity is not significant at the first area ① among the three areas ①, ② and ③, but sharply decreases at the second area ②, and is almost not significant at the third area ③. On the other hand, when the right light source unit 330R is assumed as a reference, it has a light output intensity value in the opposite order to the above order. In this way, the light output intensity formed along the length of the light transmission unit 320 can be stored in the form of a function or in the form of a plurality of points as preset data, and the light output intensity at a desired position or area can be calculated by the predetermined operation processing as described above.

[0059] The light output intensity may be controlled by adopting a configuration in which a basic light output intensity value is increased or decreased by multiplication of a predetermined value, or a value required for the lamp light source unit 330 to output light having a controlled light output intensity may be calculated.

[0060] Figure 5 3 shows the light output intensity formed along the length of the light transmission unit 320 when the light source unit 330 (330L and 330R) is turned on, and Figure 6 The light output intensity is shown along the length of the light transmission unit 320. When all the light source units 330L and 330R are turned on in response to the light output control signal, the light source units 330L and 330R disposed at both ends of the light transmission unit 320 are allowed to exhibit the same basic light output intensity.

[0061] In this embodiment, although the shape in which the light output intensity at the second region ② decreases sharply from the light source units 330L and 330R in opposite directions along the length of the light transmission unit 320 is shown, the light output intensity value, that is, the light output value at the middle point of the light transmission unit 320 transmitted from any one of the light source units 330L and 330R to the light transmission unit 320 and output from the light transmission unit 320 can be set to at least half of the light output intensity value at the end of the light transmission unit. By this configuration, as Figure 6 As shown, when the light source units 330L and 330R provided at both ends of the light transmission unit 320 are turned on to present the same basic light output intensity, the light output intensity at the second area ② can be designed to have a light output intensity value greater than the light output intensity values ​​at the first area ① and the third area ③. However, the present invention is not limited thereto, but various modifications can be made within the scope of providing a visual effect of continuous transformation of the light output intensity of each area.

[0062] exist Figures 7 to 9 , an example of the execution state of the dynamic lighting mode is shown, where the light transmission unit 320 is divided into three areas A, B and C, and the execution state of the dynamic lighting mode appears to be a visual transformation of the light wave moving sequentially from left to right through the change of the maximum point in the light output intensity. In other words, in Figure 7 In the figure, it is shown that Figure 5 When the left light source unit 330L arranged at the left end of the light transmission unit 320 is in the ON state and the right light source unit 330R arranged at the right end of the light transmission unit 320 is in the OFF state, the light output state according to the light output intensity formed from the left surface to the right of the light transmission unit 320. The light output intensity at the three areas A, B and C satisfies the following relationship: A>B>C.

[0063] Then, if Figure 8 As shown, when both the left and right light source units 330L and 330R are in the ON state, the light output intensities of the three regions A, B, and C satisfy the following relationship: B>A=C. Here, in order to perform a dynamic lighting mode, which appears to be a natural continuous transformation of the output light with a high light output intensity value, the light source control signals of the left and right light source units 330L and 330R can be controlled so that the light output values ​​of the left and right light source units 330L and 330R at the middle region B of the light transmission unit 320 are the same or substantially the same as the light output intensity value at region A, as shown in FIG. Figure 7 shown.

[0064] Afterwards, if Fig. 9 As shown, the left light source unit 330L is allowed to be in the OFF state, and the right light source unit 330R is allowed to be in the ON state, so that the light output intensities at the three areas A, B, and C satisfy the following relationship: C>B>A. In this way, a dynamic lighting mode can be performed in which a continuous change in the area where the light output intensity is the largest appears to be a sense of visual transformation of light waves.

[0065] For the purpose of this operation, the control unit 20 applies a light source control signal of a predetermined magnitude to each of the left and right light source units at a specific time.

[0066] Although it has been described in the above embodiment that the light transmitting unit 320 is implemented in a simple linear shape, the present invention is not limited thereto, but the light transmitting unit may be implemented in a curved shape.

[0067] Fig.10 10 (a) and 10 (b) show a dynamic light device provided at the interior trim of a vehicle door and a graph of light output intensity formed along the length of the dynamic light device, which is consistent with Figure 5 and Figure 6Even in the case where the light transmitting unit 320 is formed in a curved shape instead of a linear shape due to the material properties of the light transmitting unit 320 made of a light guide material, it exhibits almost similar characteristics to the case of being formed in a linear shape. Figures 11 to 13 The operating state of the dynamic light device that performs the dynamic lighting mode along the length of the light transmission unit is shown, and the dynamic light device is divided into three areas. This operating state of the dynamic light device is almost the same as the above Figures 7 to 9 In addition, by controlling the output amplitude of the light source control signal at the lamp light source units disposed at both ends of the light transmission unit, a dynamic lighting mode can be performed, which exhibits a predetermined visual effect, that is, allowing the light wave to move with the light output intensity value presented as the maximum output value of the single lamp light source unit at both ends of the light transmission unit and with the light output intensity value presented as the light overlapping in the central area.

[0068] In the aforementioned embodiment, the number of regions divided along the length of the light transmission unit of the dynamic light device according to the present invention is set to three, but the present invention is not limited thereto. Fig.14 As shown, along the length of the dynamic light device, more specifically along the length of the dynamic light device, the light transmission unit is divided into a total of five areas A, B, C, D and E. A light source control signal for controlling the light output intensity of the light source unit disposed at both ends of the light transmission unit is applied to the light source unit to achieve a predetermined dynamic lighting mode of the plurality of five areas.

[0069] [Table 1]

[0070]

[0071] In this case, Table 1 shows different light output intensities based on the maximum output intensities of the left and right light source units 330L and 330R, and based on the Fig.14The five operating stages of the light transmission unit 320 are divided along the length of the light transmission unit 320, and the areas A to E have different light output intensities of the maximum output intensity. Here, the area representing the maximum light output intensity of each operating stage is represented by a dark color. Unlike the three areas described above, the light output intensity value at the area with the maximum output intensity at each operating stage has a certain deviation relative to each operating stage due to the number of areas subdivided over the entire length of the light transmission unit. The deviation can be controlled so that it is impossible to visually identify the deviation through the faster transition of each operating stage. In addition, in some cases, the deviation of the maximum light output intensity value of each area can be controlled in the following manner. For example, when transitioning from the first operating stage ① to the second operating stage ②, the light output intensity of the left light source unit does not change from 100% to 80% immediately, but for each operating stage, the change in the light output intensity of the light source unit is implemented in a non-intermittent but intermittent segmented manner or in a substantially continuous manner, as if the value between the light output intensity 100% and 80% is subdivided and continuously changed by different values ​​of 2% during the interval time between each operating stage, so that the user can be provided with a visual effect of a dynamic lighting mode without a sense of unevenness.

[0072] Hereinafter, a method for controlling a dynamic light device 10 according to another aspect of the present invention will be described in detail with reference to the accompanying drawings.

[0073] Figures 15 to 17 A flow chart showing a control method of the dynamic light device 10 of the present invention is shown.

[0074] First, the method for controlling a dynamic light device of the present invention includes a setting step S10 of setting the dynamic light device 10, and the description of the execution of the setting step S10 will be replaced by the aforementioned related description.

[0075] After the setting step S10 of setting the dynamic light device 10 has been performed, the control unit 20 performs the input step S20. In the input step S20, the input signal input by the user through the input unit 60 is applied to the control unit 20. In other words, in the input step S20, the input signal input by the user through the input unit 60 and applied to the control unit 20 includes a mode input signal for selecting a lighting mode that the user wishes to perform by the dynamic light device 10. Then, the mode input signal is applied to the control unit 20, and then information about the operation mode that the user desires to perform is stored in the storage unit 30.

[0076] Thereafter, the control unit 20 performs a mode determination step S30. In the mode determination step S30, the control unit 20 determines an operation mode selected based on the mode input signal and preset data.

[0077] The mode determination step S30 includes a mode input signal confirmation step S31, a dynamic mode determination step S33 and a mode setting step S35 / S37.

[0078] In the mode input signal confirmation step S31, the control unit 20 confirms the application of the mode input signal input by the user through the input unit 60 and stored in the storage unit 30. Then, the procedure proceeds to the dynamic mode determination step S33, in which the control unit 20 determines whether the operation mode selected by the user is a dynamic mode or a static mode based on the mode input signal and the preset data stored in the storage unit 30. Here, the static mode means an output mode that outputs simple light in a fixed state as described above, and the dynamic mode means a predetermined lighting mode that continuously changes the output signal for visual recognition so that dynamic changes in the lighting state can be visually recognized.

[0079] In other words, the control unit 20 determines whether the operation mode selected by the user is a static mode that merely maintains the output state of light in a fixed state, or a dynamic mode that generates visual changes.

[0080] In the mode setting step S35 / S37, the control unit 20 finally sets the operation mode to be executed by the control unit 20 based on the determination result in the dynamic mode determination step S33, and stores the finally set operation mode in the storage unit 30. In other words, if it is determined as a result of the determination in step S33 that the operation mode selected by the user is the dynamic mode, the program proceeds to the dynamic mode setting step S35, wherein the control unit 20 performs the dynamic mode setting step S35 to set the dynamic mode as the mode to be executed. On the contrary, if it is determined as a result of the determination in step S33 that the operation mode selected by the user is the static mode, the program proceeds to the static mode setting step S37, wherein the control unit 20 performs the static mode setting step S37 to set the static mode as the mode to be executed.

[0081] Subsequently, the control unit 20 performs the mode execution step S40. In the mode execution step S40, the control unit 20 applies a light source control signal as an operation control signal to the lamp light source unit 330 to execute the operation mode determined in the dynamic mode setting step S35.

[0082] More specifically, the mode execution step S40 includes a set operation mode confirmation step S41 and a dynamic mode execution step S43. In the set operation mode confirmation step S41, the control unit 20 confirms the operation mode set in the mode determination step S30, and in the dynamic mode execution step S43, if it is determined that the set operation mode confirmed in the set operation mode confirmation step S41 is the dynamic mode, the control unit 20 executes the dynamic mode. The dynamic mode execution step S43 includes a dynamic data confirmation step S431, a light source signal calculation step S433, and a light source unit dynamic output step S435.

[0083] In the dynamic data confirmation step S431, the control unit 20 confirms the dynamic data included in the preset data. The dynamic data is a value that forms a state of the light output intensity level of 100%, 80%, 70%, 30% and 0% as shown in Table 1 above to output a value of the basic light output intensity of the light output from the light source unit 330, such as a maximum light output intensity value. The dynamic data contains a function of the light output intensity value formed along the length of the light transmission unit 320, point data about a plurality of related points, and data about a light source control signal, which is an electrical signal applied to the light source unit to form the function and the point data. In addition, as an operation mode selected by the user, the dynamic data may contain information about the number of areas divided along the entire length of the light transmission unit, and information about the advancing direction of the area having the maximum light output intensity among the areas divided along the entire length of the light transmission unit.

[0084] As described above, when an intermediate value of data included in the dynamic data is required, the operation unit 40 may calculate the intermediate value through a predetermined operation process in response to an operation control signal from the control unit 20 .

[0085] Thereafter, the control unit 20 may control the light output intensity by taking a configuration in which the intermediate value is large or small through an operation process such as multiplication of certain values ​​of the dynamic data, or the control unit 20 may control the operation process of the operation unit 40 so that calculation of the value required by the lamp light source unit 330 is performed so that light having a controlled light output intensity can be output. Then, the control unit 20 performs the lamp light source signal calculation step S433.

[0086] In the light source signal calculation step S43, the control unit 20 controls the operation unit 40 to calculate a plurality of time-related individual signals to be output from the light source unit according to the mode input signal and the dynamic data as preset data.

[0087] Subsequently, in the light source signal calculation step S433 , the control unit 20 outputs a plurality of time-correlated individual signals of the light source unit calculated in the light source signal calculation step S433 to be applied to the light source unit 330 .

[0088] Through such a control process, a lighting mode can be executed, which enables visual identification of dynamic changes in the lighting state, which are caused by sequential changes in the light output intensity of the areas divided along the entire length of the light transmission unit 320, and by sequential changes in the areas with maximum light output intensity among the areas divided along the entire length of the light transmission unit 320.

[0089] On the other hand, Fig.17 As shown, the mode execution step S40 also includes a static mode execution step S45. If it is determined in the set operation mode confirmation step S41 that the operation mode set in the mode determination step S30 is the static mode, the program proceeds to the static mode execution step S45, wherein the control unit 20 executes the static mode execution step S45. The static mode execution step S45 includes a static data confirmation step S451, a single output signal calculation step S453 of the light source unit, and a static output step S455 of the light source unit.

[0090] In the static data confirmation step S451, the control unit 20 confirms static data included in the preset data. The static data represents information on the light output intensity of light output from the lamp light source unit 330 in a substantially fixed state.

[0091] Thereafter, the controller unit 20 may control the light output intensity, either based on static data or by controlling the operation processing of the operation unit 40, thereby realizing the calculation of the value required for the lamp light source unit 330 so as to output light with the controlled light output intensity. Then, the program proceeds to the single output signal calculation step S453 of the lamp light source unit, where the control unit 20 performs the single output signal calculation step S453 of the lamp light source unit.

[0092] In the single output signal calculation step S453 of the lamp light source unit, the control unit 20 controls the operation unit 40 to calculate the light source control signal to be output from the lamp light source unit according to the mode input signal and the static data.

[0093] Subsequently, the procedure proceeds to the static output step S455 of the lamp light source unit, in which the control unit 20 outputs the light source control signal of the lamp light source unit calculated in the single output signal calculation step S453 of the lamp light source unit to be applied to the lamp light source unit 330 .

[0094] Meanwhile, the dynamic light device 10 according to the present invention may include a configuration in which the combination of the light output intensity of the light output from the light transmission unit along the entire length of the light transmission unit is more smoothly implemented to further enhance the execution of the dynamic lighting mode. For example, by generally linearizing the length-dependent change of the light output intensity of the light output from the light transmission unit along the entire length of the light transmission unit, a configuration may be implemented in which, when the combination of the light emitted from the left and right light source units is implemented at both ends of the light transmission unit, a continuous change of the area or position having the maximum light output intensity becomes easy according to the length or area of ​​the light transmission unit.

[0095] To this end, the light transmitting unit 320 of the dynamic light device 10 of the present invention may include a predetermined surface pattern unit disposed on a surface thereof.

[0096] The surface pattern unit 400 may protrude in a protrusion shape on the surface of the light transmitting unit 320. In this embodiment, the surface pattern unit 400 includes a triangular protrusion shape relative to a plane including the length of the light transmitting unit (see FIG. Fig.18 ). The light transmitting unit 320 includes a light transmitting body 321 and a light transmitting stepped portion 323 formed in a stepped manner on the top surface of the light transmitting body 321. The light transmitting body 321 generally has a circular tube shape. Preferably, the light transmitting stepped portion is formed to perform a smooth embossing process on a surface pattern unit on one surface of the light transmitting body 321.

[0097] The surface pattern unit 400 is formed in a triangular protrusion shape, wherein when viewed from a plane perpendicular to the length direction of the light transmitting unit, the length of the base of the surface pattern unit 400 is represented by l, the height thereof is represented by d, and the width thereof is represented by w. The length l of the base of the surface pattern unit 400 is set to have the same value with respect to a plurality of surface pattern units, and the arrangement distance of the triangular protrusion formed along the length of the light transmitting unit 320 is represented by s.

[0098] More specifically, the surface pattern unit 400 includes a light exit surface 414a formed thereon, and the direction of the light exit surface 414a is the direction in which at least one light source unit 330 is directed toward another light source unit. Fig.18 As shown, the surface of the surface pattern unit 400 facing the direction in which the light emitted from the light source unit 330 provided at the right end of the light transmission unit 320 is transmitted is formed as a light exit surface 414a. The light exit surface 414a according to one embodiment of the present invention may be unevenly processed for smooth emission of light toward the relevant direction. The light exit surface 414a may be surface-processed so that light emission in a desired direction is achieved by preventing total reflection of light through uneven surface processing such as laser etching.

[0099] On the contrary, Fig.18 Unlike the case in FIG. 1 , the plurality of surface pattern units 413d may be formed to have a structure in which the advancing direction of light emitted from the left light source unit opposite to the right light source unit is formed to be aligned with the left light source unit. Fig.18 The surface pattern units 413d may be evenly dispersed as shown in the figure, thereby being able to form a linear light output intensity pattern of light emitted from each direction of the surface pattern units.

[0100] Such a surface pattern unit may have a configuration such that its angle, height and width vary along the length of the light transmitting unit.

[0101] Fig. 20 and Fig.21 shows left- and right-facing surface pattern units based on angle, Fig. 22 and Fig.23 shows the left- and right-facing surface pattern units based on height, Fig.24 and Fig.25 Left- and right-facing surface pattern elements are shown based on width.

[0102] exist Figure 20 to Figure 25 In each of the figures, left and right oriented surface pattern units (413-1, 413-2 and 413-3; 413-1d, 413-2d and 413-3d) are shown to change from any one of the light source units 330L and 330R to the other along the length of the light transmission unit 320. The structural change of the left and right oriented surface pattern units along the length of the light transmission unit is associated with the light exit surface 414a oriented from the light source unit disposed at the other end of the light transmission unit toward the light source unit disposed at either end of the light transmission unit. As described above, the surface pattern units corresponding to the left and right light source units can be modified in various ways, such as being dispersedly disposed on the surface of the light transmission unit, such as Fig.32 shown.

[0103] like Figure 20 to Figure 25As shown, the surface pattern unit 400 includes a light exit surface 414, which is oriented in a direction in which the light exit surface 414 travels from at least one of the light source units 330 toward another of the light source units 330, and a light exit angle (θ413-1, θ413-2, θ413-3; θ413-1d, θ413-2d, θ413-3d) formed between the light exit surface 414 of the surface pattern unit 400 and the surface of the light transmission unit 320 increases or becomes equal sequentially as it travels from at least one of the light source units 330 toward another thereof, and vice versa (θ413-1≤θ413-2≤θ413-3; θ413-1d≤θ413-2d≤θ413-3d).

[0104] In addition, the heights (d413; d413-1, d413-2, d413-3; d413-1d, d413-2d, d413-3d) of the surface pattern units 400 starting from the surface of the light transmission unit 320 successively decrease or become equal as proceeding from at least one of the light source units 330 toward another thereof, and vice versa (d413-1≥d413-2≥d413-3; d413-1d≥d413-2d≥d413-3d).

[0105] In addition, the width (w413) of the surface pattern unit 400, when projected onto a plane parallel to the length direction of the light transmission unit 320, decreases or becomes equal as it moves from at least one of the light source units 330 to another one thereof, and vice versa (w413-3≤w413-2≤w413-1; w413-3d≤w413-2d≤w413-1d).

[0106] Due to this mechanical characteristic, a linear pattern of light output intensity formed along the length of the light delivery unit can be achieved, thereby enabling the implementation of a dynamic lighting mode that employs a minimum number of light source units arranged along the length of the light delivery unit 320.

[0107] Meanwhile, in the aforementioned embodiment, the surface pattern unit has a triangular embossed convex shape, but the present invention is not limited thereto. In other words, the surface pattern unit 400 may be engraved into a concave shape on the surface of the light transmitting unit 320, such as Fig.19 shown.

[0108] The surface pattern unit 400 may be engraved into a concave shape on the surface of the light transmitting unit 320. In this embodiment, the surface pattern unit 400 is relatively large relative to the light transmitting unit (see Fig.19) has a triangular concave shape. The light transmitting unit 320 generally has a cylindrical tube shape. The surface pattern unit 400 is preferably formed in the shape of a triangular concave 412a directly engraved on the surface of the light transmitting unit 320.

[0109] The surface pattern unit 400 is formed in a triangular concave shape, wherein when viewed from a plane perpendicular to the length direction of the light transmitting unit, the length of the base of the surface pattern unit 400 is represented by l, its height (depth) is represented by d, and its width is represented by w. The length l of the base of the surface pattern unit 400 is set to have the same value with respect to a plurality of surface pattern units, and the arrangement distance of the triangular concave formed along the length of the light transmitting unit 320 is represented by s.

[0110] More specifically, the surface pattern unit 400 includes a light exit surface 414a formed thereon, and the direction of the light exit surface 414a is the direction in which at least one light source unit 330 is directed toward another light source unit. Fig.18 As shown, the surface of the surface pattern unit 400 facing the direction in which the light emitted from the light source unit 330 provided at the right end of the light transmission unit 320 is transmitted is formed as a light exit surface 414a. The light exit surface 414a according to one embodiment of the present invention may be unevenly processed for smooth emission of light toward the relevant direction. The light exit surface 414a may be surface-processed so that the total reflection of light is prevented by uneven surface processing such as laser etching to achieve light emission in a desired direction. This is the same as the case where the surface pattern unit 400 is embossed as described above.

[0111] like Figure 26 to Figure 31 As shown, the surface pattern unit 400 includes a light emitting surface 414a in a direction proceeding from at least one of the light source units 330 toward another thereof, and light emitting angles (θ413-1a, θ413-2a, θ413-3a; θ413-1ad, θ413-2ad, θ413-3ad) formed between the light emitting surface 414a of the surface pattern unit 400 and the surface of the light transmission unit 320 successively decrease or become equal as proceeding from at least one of the light source units 330 toward another thereof, and vice versa (θ413-1a, θ413-2a, θ413-3a; θ413-1ad, θ413-2ad, θ413-3ad).

[0112] In addition, the heights (depths, d413-1a, d413-2a, d413-3a; d413-1ad, d413-2ad, d413-3ad) of the surface pattern units (400) starting from the surface of the light transmission unit (320) successively decrease or become equal as they proceed from at least one of the light source units 330 to another one thereof, and vice versa (d413-3a≤d413-2a≤d413-1a; d413-3ad≤d413-2ad≤d413-1ad).

[0113] In addition, the width (w413) of the surface pattern unit 400, when projected onto a plane parallel to the length direction of the light transmission unit 320, decreases or becomes equal as it moves from at least one of the light source units 330 toward another one thereof, and vice versa (w413-3a≤w413-2a≤w413-1a; w413-3ad≤w413-2ad≤w413-1ad).

[0114] In addition, at the same time, although the dynamic light device and the control method thereof according to the present invention have been described intensively in the above embodiments, it can be implemented in various ways according to the design specifications, such as being installed in the indoor or outdoor space of the vehicle other than the door within the scope of realizing the predetermined dynamic lighting function. In some cases, the dynamic light device and the control method thereof according to the present invention can also be implemented in a device other than the vehicle.

[0115] The above embodiments are merely examples for explaining the present invention and are not intended to limit the present invention. For example, although the shape of the light transmission unit 320 has been described as being centered on a linear or curved shape in the above embodiments according to the present invention, the light transmission unit of the present invention may have a branch structure, such as a three-branch line structure, in which one end is arranged on the left side of the light transmission unit and both ends are arranged on the right side thereof, and may be modified in various ways according to design specifications. For example, the configuration may be centered on the combination of the colors of the light of each region rather than its light output intensity.

[0116] Industrial Applicability

[0117] Although the dynamic light device and the control method thereof according to the present invention have been described focusing on its installation in the interior space of a vehicle, it can be implemented in various ways according to the design specifications, such as being installed as indoor lighting or installed in the interior space of an aircraft, including installing it in the indoor or outdoor space of a vehicle rather than in the door of the vehicle within the scope of realizing a predetermined dynamic lighting function. In some cases, the dynamic light device and the control method thereof according to the present invention can also be implemented in devices other than vehicles.
