[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp for a vehicle, and more particularly, to a lamp for a vehicle which realizes a three-dimensional shape by allowing light of a light source to pass through a lenticular lens.

2. Description of the Related Art Generally, a vehicle includes a lamp module having a lighting function for easily identifying an object located in the vicinity of the vehicle at nighttime, and a signal function for notifying other vehicle or road users of the traveling state of the vehicle.

For example, headlights and fog lights are aimed at lighting functions, and turn signal lights, taillights, brake lights, side markers and the like are intended for signal functions.

In recent years, the lamp module has exceeded merely the lighting function and the signal function, so that a specific type of light is emitted to the outside, thereby improving the visibility and improving the perception of the product of a specific maker.

On the other hand, it is not easy to have differentiation from other products through it because it has been a long-lasting technology to transform the shape of light emitted to the outside.

Therefore, the emergence of an invention for a vehicle lamp that can give a clearer differentiation from other products is required.

Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

FIG. 1 is a view illustrating a lamp for a vehicle according to an embodiment of the present invention, and FIG. 2 is a view showing diffusion of light in a diffusion lens according to an embodiment of the present invention.

1 and 2, a vehicle lamp 10 includes a light source 100 and a lenticular lens 200.

The light source 100 serves to irradiate light. The light of the light source 100 may be irradiated in the form of a direct light or indirectly. To this end, a reflector (not shown) for reflecting light may be provided around the light source 100, and a light guide (not shown) such as a light guide may be provided.

The lenticular lens 200 functions to diffuse the incident light to form a certain type of light pattern. The lenticular lens 200 may include at least one diffusion lens 210. The diffusion lens 210 may have the shape of a columnar column. At least one diffusing lens 210 may be arranged adjacent to each other to constitute the lenticular lens 200.

Referring to FIG. 2, the diffusion lens 210 may diffuse the incident light. The light incident on the back surface of the diffusion lens 210 is diffused in a plurality of directions while being emitted to the front surface. The diffusion direction of the light can be determined in a direction perpendicular to the long axis of the diffusion lens 210. [ That is, light is diffracted and diffused at the curved surface portion of the front surface of the diffusion lens 210.

In the present invention, the light source 100 may be an LED (Light Emitting Diode). The pattern of light irradiated by the light source 100, such as an LED, may have a point shape. That is, when the observer views the LED, a light pattern having a shape of a point can be recognized.

A light pattern having a point shape is incident on at least one diffusing lens 210 constituting the lenticular lens 200, and each diffusing lens 210 diffuses the incident light in a direction perpendicular to the long axis. A light pattern diffused by each diffusion lens 210 is connected to adjacent light patterns and accordingly a light pattern having a line shape can be formed.

FIGS. 3 and 4 are diagrams illustrating the formation of a light pattern by the lenticular lens according to the embodiment of the present invention.

Referring to FIGS. 3 and 4, a light pattern is formed as the light from the light source 100 is incident on the lenticular lens 200. As the light pattern of the light source 100 having the shape of a dot is diffused by the diffusion lens 210 of the lenticular lens 200, a line-shaped light pattern L is formed and recognized by an observer. The observer can recognize one light pattern L having the shape of a line even if viewed from any direction.

Meanwhile, light from the light source 100 may be incident on a plurality of points of the lenticular lens 200. In addition, as described above, the incident light is refracted by the diffusing lens 210 and emitted. Here, a plurality of lights diffused and emitted from the plurality of diffusion lenses 210 are incident on both sides of the observer at a position spaced apart from the front portion of the lenticular lens 200 by a certain distance. The position of the line-shaped light pattern recognized by the observer is a position F spaced apart from the lenticular lens 200 by a certain distance, not on the surface of the lenticular lens 200. [ That is, it can be understood that the lenticular lens 200 forms a light pattern by transmitting light.

In this way, a light pattern L in the form of a line can be formed by transmitting light through the lenticular lens 200 constituted by at least one diffusion lens 210. Here, the width and the curvature of the diffusion lens 210 can be variously determined. The shape of the light pattern recognized according to the width and the curvature of the diffusion lens 210 can be changed.

5 to 7 are views showing a lamp for a vehicle according to another embodiment of the present invention. Fig. 5 is a perspective view of the lamp for a vehicle, Fig. 6 is a side view of the lamp for a vehicle, and Fig. 7 is a front view of the lamp for a vehicle.

5 to 7, the vehicle lamp 20 includes a light source 100 and an optical unit 300. [

The light source 100 serves to irradiate light. Since the light source 100 has been described above, a detailed description will be omitted. However, the vehicle lamp 20 according to another embodiment of the present invention may include a plurality of light sources 100 corresponding to the plurality of lenticular lenses 310, 320, 330, and 340.

The optical unit 300 transmits light and forms a light pattern. The optical unit 300 may include a plurality of lenticular lenses 310, 320, 330, and 340 disposed on the same plane. The plurality of lenticular lenses 310, 320, 330, and 340 each including at least one diffusion lens may be disposed on the same plane so that the angle between the long axes of the diffusion lenses provided in the adjacent lenticular lenses is not parallel. Here, the same surface on which the plurality of lenticular lenses 310, 320, 330, and 340 are disposed includes a plane or a curved surface. Hereinafter, a plurality of lenticular lenses 310, 320, 330, and 340 are disposed on the same plane.

Each of the plurality of lenticular lenses 310, 320, 330, and 340 may be formed at an oblique angle with respect to the longitudinal axis of the diffusion lens, and may have a contiguous boundary adjacent to another lenticular lens.

Figs. 5 and 7 show optical parts composed of four lenticular lenses 310, 320, 330 and 340. Fig. Each lenticular lens may have a contiguous boundary formed at an oblique angle to the long axis of the diffusion lens. Thus, each of the adjacent boundaries of the adjacent lenticular lenses can be in contact with each other so that one optical unit 300 can be constructed.

As the adjacent boundary is formed at an oblique angle to the long axis of the diffusing lens, the line-shaped light pattern formed by each lenticular lens can meet at the adjacent boundary. The position of the light pattern is determined by the position of the light source 100. A plurality of light sources 100 may be arranged such that a line-shaped light pattern formed by each of the lenticular lenses overlaps at least a part of the adjacent boundary.

5 and 7 show that three light sources 100 are arranged correspondingly for each lenticular lens. As the light by the three light sources 100 is incident, each lenticular lens can form three light patterns having the shape of a line.

8 is a view showing a light pattern formed by the lamp 20 for a vehicle shown in Figs. 5 to 7. Fig.

Referring to FIG. 8, each lenticular lens may form three light patterns L having the shape of a line. Further, each light pattern may meet with a different light pattern at the adjacent boundary.

Fig. 8 shows that all three light patterns L formed by the respective lenticular lenses meet with different light patterns at the adjacent boundary. That is, a plurality of closed graphic forms in which light of a plurality of light sources 100 is transmitted through a plurality of lenticular lenses 310, 320, 330, and 340 and formed of lines can be formed. For this purpose, the shape of the adjacent boundary by each lenticular lens and the arrangement of the light sources 100 can be appropriately determined.

Meanwhile, according to some embodiments of the present invention, some or all of the light patterns formed in the respective lenticular lenses may not meet the light patterns formed in the adjacent lenticular lenses.

5 and 7, since the shape of each lenticular lens has an isosceles triangle shape, the shape of the entire optical pattern formed by the optical portion 300 may be rectangular. However, the shapes of the lenticular lenses 310, 320, 330, and 340 constituting the optical unit 300 of the present invention are not limited thereto, and any shape may be used as long as the adjacent boundary is obliquely formed on the long axis of the diffusion lens .

9 is a view showing a change in a light pattern according to a distance between a lenticular lens and a light source according to an embodiment of the present invention.

Referring to FIG. 9, a plurality of light sources 110 and 120 having different distances from the lenticular lens 200 may be provided.

On the other hand, since the light from the light sources 110 and 120 is diffused and irradiated, the vertical cross section of the light can be increased as the distance from the lenticular lens 200 increases. As described above, the pattern of the light irradiated by the light source may have a point shape. Therefore, it can be understood that the larger the distance from the light source, the larger the size of the light pattern (hereinafter referred to as the dot pattern) having the shape of the point.

The lenticular lens 200 forms a light pattern (hereinafter referred to as a line pattern) having a line shape by diffusing the incident light in a direction perpendicular to the long axis of the diffusion lens. Accordingly, the width of the line pattern formed by the lenticular lens 200 can be increased as the incident point pattern becomes larger.

9 shows a line pattern Ls by the light source 110 disposed relatively close to the lenticular lens 200 and a line pattern Lw by the light source 120 located relatively far from the lenticular lens 200 . The width of the line pattern Lw by the light source 120 disposed relatively far from the lenticular lens 200 is smaller than the width of the line pattern Ls by the light source 120 disposed relatively close to the lenticular lens 200, As shown in FIG.

However, the line pattern Ls having a small width is formed by concentrated energy, and the line pattern Lw having a large width is formed by dispersing energy. Therefore, the line pattern Ls having a small width can be observed more clearly than the line pattern Lw having a large width.

10 and 11 are views showing a lamp for a vehicle according to another embodiment of the present invention. Fig. 10 is a side view of the lamp for a vehicle, and Fig. 11 is a front view of the lamp for a vehicle.

10 and 11, the vehicle lamp 30 includes the light sources 100 and 120 and the optical unit 300. [

The light sources 110 and 120 serve to irradiate light. Since the functions of the light sources 110 and 120 are the same as or similar to those of the light source 100 described above, detailed description thereof will be omitted. The vehicle lamp 30 according to the embodiment of the present invention may include a plurality of light sources 110 and 120 corresponding to the plurality of lenticular lenses 310, 320, 330 and 340, And 120 and the optical unit 300 may be different from the distance between the rest of the plurality of light sources 110 and 120 and the optical unit 300. That is, the light sources 110 and 120 may include a first light source 110 disposed relatively close to the optical unit 300 and a second light source 120 disposed relatively far from the optical unit 300.

The optical unit 300 transmits light and forms a light pattern. The optical unit 300 includes a plurality of lenticular lenses 310, 320, 330, and 340, and at least one light source corresponding to each lenticular lens may be disposed. Since the optical unit 300 has been described above, a detailed description thereof will be omitted.

A light pattern is formed as the light from the light sources 110 and 120 is transmitted through the optical unit 300. At least one of the light intensity and the sharpness of the light pattern depends on the distance between the light sources 110 and 120 and the optical unit 300 Can be determined. For example, as the distance between the light sources 110 and 120 and the optical unit 300 is closer, at least one of the brightness and clarity of the light pattern is increased and the distance between the light sources 110 and 120 and the optical unit 300 becomes longer At least one of the brightness and sharpness of the recorded light pattern may be lowered.

In addition, a line pattern having a different width may be formed on the entire surface of the optical unit 300 by the light sources 110 and 120 having different distances from the optical unit 300. 12 shows that the line patterns Ls and Lw having different widths are formed on the entire surface of the optical portion 300. In Fig. The width of the line pattern becomes narrower as the distance between the light sources 110 and 120 and the optical portion 300 becomes shorter and the line pattern becomes wider as the distance between the light sources 110 and 120 and the optical portion 300 becomes longer .

The light source 110 disposed close to the optical unit 300 forms a line pattern Ls having a narrow width while at least one of the brightness and the sharpness is high and the light source 120 distant from the optical unit 300 A wide line pattern Lw can be formed while at least one of the luminous intensity and the sharpness is low.

12 illustrates a rectangular light pattern, various types of light patterns may be formed depending on the shapes of the lenticular lenses 310, 320, 330, and 340 that constitute the optical unit 300. FIG.

FIG. 13 is a view showing an optical unit according to another embodiment of the present invention, and FIG. 14 is a view illustrating a lamp for a vehicle in which a light source is disposed on the back surface of the optical unit of FIG.

Referring to Figs. 13 and 14, the vehicle lamp 40 includes light sources 110 and 120 and an optical unit 301. Since the light sources 110 and 120 have been described above, a detailed description thereof will be omitted. Alternatively, at least one light source having the same distance as the optical portion 301 may be provided.

The optical unit 301 includes a plurality of lenticular lenses 311, 321, 331, and 341 having at least one diffusion lens having a width varying along a major axis and forming a curved light pattern as the light of the light source is transmitted therethrough can do.

In particular, as shown in Figs. 13 and 14, a diffusing lens may be disposed in each lenticular lens so that the small-width end of the diffusing lens is concentrated at one position.

As the width changes along the long axis, the light patterns formed by each of the plurality of diffusion lenses can be connected to each other to form a curve.

Figs. 15 and 16 are diagrams showing a light pattern formed by the vehicle lamp of Fig. 14. Fig.

Referring to FIGS. 15 and 16, a curved light pattern is formed as light is transmitted through a plurality of diffusion lenses whose widths vary along a major axis.

As shown in FIG. 15, a plurality of curves may be connected to form circles Cs and Cw, and a plurality of curves As and Aw may be cut off to form a unique shape as shown in FIG. 16 . Various types of light patterns can be implemented depending on the positions of the light sources 110 and 120 disposed on the back surface of the optical unit 301. [

It is also possible to form line patterns Cs, Cw, As, and Aw that are wide or narrow depending on the positions of the light sources 110 and 120.

17 is a view illustrating a lamp for a vehicle according to another embodiment of the present invention.

17, the vehicle lamp 50 includes a light source 100 and an optical unit 201. [

The light source 100 serves to irradiate light. Since the light source 100 has been described above, a detailed description will be omitted. The vehicle lamp 50 according to another embodiment of the present invention includes a plurality of light sources 1000 corresponding to the plurality of lenticular lenses 211, 221, 231, 241, and 251 constituting the optical unit 201 .

The optical unit 201 transmits light and forms a light pattern. The optical unit 201 may include a plurality of lenticular lenses 211, 221, 231, 241, and 251 disposed on the same plane. Each lenticular lens may have a long rod shape, and a plurality of diffusing lenses may be disposed along the long axis of the lenticular lenses 211, 221, 231, 241, and 251. Here, the long axis of the lenticular lenses 211, 221, 231, 241, and 251 and the long axis of the diffusing lens may be right angles.

At least one light source 100 may be disposed on the back surface of each lenticular lens. 17 shows the arrangement of the light sources 100 in a line along the longitudinal axes of the respective lenticular lenses 211, 221, 231, 241 and 251. However, the arrangement of the light sources 100 of the vehicle lamp 50 of the present invention The present invention is not limited thereto. Hereinafter, the light sources 100 are arranged in a line along the longitudinal axes of the lenticular lenses 211, 221, 231, 241, and 251, respectively.

The light of each light source 100 is irradiated with a corresponding lenticular lens, and the lenticular lens can transmit light to form a line pattern.

18 is a view showing a light pattern formed by a lamp for a vehicle according to another embodiment of the present invention.

Referring to FIG. 18, each of the lenticular lenses 211, 221, 231, 241, and 251 can transmit a light to form a light pattern L in a line shape. That is, the optical portion 201 can form a light pattern corresponding to the arrangement shape of the lenticular lenses 211, 221, 231, 241, and 251.

Various types of light patterns can be formed depending on the arrangement of the plurality of lenticular lenses 211, 221, 231, 241, and 251. [ For example, when a plurality of lenticular lenses 211, 221, 231, 241 and 251 are arranged in the form of regular hexagon, a light pattern of a regular pentagon is formed, and a plurality of lenticular lenses 211, 221, 231, 241 and 251 ) Are arranged in the form of a star, a star-shaped light pattern is formed. Here, each of the light patterns may be formed by combining light patterns in the form of a line.

As described above, it is possible to form a light pattern of complicated shapes combining a line-shaped light pattern with a plurality of lenticular lenses 211, 221, 231, 241, and 251 and a small number of light sources.

19 is a view showing a curved lenticular lens according to an embodiment of the present invention.

Referring to FIG. 19, the curved lenticular lens 500 may include at least one diffusion lens 510 whose width changes along the major axis. The curved lenticular lens 500 can form a curved light pattern as the light of the light source is transmitted.

Fig. 20 is a view showing a light pattern formed by adding the lenticular lens of Fig. 19 to the vehicle lamp of Fig. 17;

Referring to FIG. 20, the curved lenticular lens 500 may be disposed between the linear lenticular lenses 211, 221, 231, 241, and 251.

The curved light pattern formed by the curved lenticular lens 500 can connect the ends of the light pattern L of the line shape formed by the adjacent lenticular lenses 211, 221, 231, 241, and 251, respectively.

The width change rate and the number of diffusion lenses constituting each curved lenticular lens 500 can be determined according to the shape between the adjacent linear lenticular lenses 211, 221, 231, 241, and 251. In addition, a light source (not shown) for irradiating light with the curved lenticular lens 500 may be provided for each curved lenticular lens.

As the curved lenticular lens 500 is disposed between the adjacent linear lenticular lenses 211, 221, 231, 241, and 251, it becomes possible to implement a light pattern that is connected in its entirety.

21 to 23 are views showing a lamp for a vehicle according to another embodiment of the present invention. Fig. 21 is a perspective view of the vehicle lamp, Fig. 22 is a side view of the vehicle lamp, and Fig. 23 is a front view of the lamp for a vehicle.

21 to 23, the vehicle lamp 21 is configured to include a light source 101, an optical unit 302, and a reflector 400. [

The light source 101 serves to irradiate light. Since the light source 101 has been described above, a detailed description thereof will be omitted. However, the vehicle lamp 21 according to another embodiment of the present invention may include a plurality of light sources 101 corresponding to the plurality of lenticular lenses 312, 322, 332, and 342.

The reflector 400 is provided around the light source 101 and reflects the light of the light source 101. The light reflected by the reflector 400 can be irradiated to the optical portion 302. The vehicle lamp 21 may include one reflector for reflecting the light of the entire light source, and may include a plurality of reflectors for reflecting the light of some of the plurality of light sources. Alternatively, the vehicle lamp 21 may include a reflector 400 for each light source 101, as shown. Hereinafter, the reflector 400 is provided for each light source 101. FIG.

The optical unit 302 transmits the light reflected by the reflector 400 to form a light pattern. The optical unit 302 may include a plurality of lenticular lenses 312, 322, 332, and 342.

The shapes and functions of the optical portion 302 and the plurality of lenticular lenses 312, 322, 332 and 342 are the same as those of the optical portion 300 and the plurality of lenticular lenses 310, 320, 330, May be the same or similar. Therefore, the same surface on which the plurality of lenticular lenses 312, 322, 332, and 342 are disposed includes a plane or a curved surface. Hereinafter, the same plane on which the plurality of lenticular lenses 312, 322, 332, and 342 are disposed will be mainly described.

Figs. 21 and 23 show an optical section 302 composed of four lenticular lenses 312, 322, 332, and 342. Fig. Each lenticular lens may have a contiguous boundary formed at an oblique angle to the long axis of the diffusion lens. Thus, each of the adjacent boundaries of the adjacent lenticular lenses can be in contact with each other so that one optical unit 302 can be constructed.

21 and 23 show that three light sources 101 are arranged correspondingly for each lenticular lens. As the light by the three light sources 101 is incident, each of the lenticular lenses 312, 322, 332, and 342 can form three light patterns having the shape of a line.

24 is a view showing an incidence section of light incident on the optical section according to the embodiment of the present invention.

In the present invention, the incidence surfaces (S1, S2, S3) represent the cross section of the light mapped to the incident surface of the optical portion 302 among the light incident on the optical portion 302.

The reflected light from the light source 101 and the reflector 400 can have a shape of a point as in the case of the direct light of the light source 101. [ That is, both the light patterns of the direct light and the reflected light can have a dot shape. However, the area of the light pattern may vary depending on whether the reflector 400 is applied or not, and the light diffusion range of the reflector 400.

In the case of direct light, since the light pattern is determined by the light irradiation angle inherent to the light source 101, the incident surface S1 is formed relatively small.

On the other hand, in the case of reflected light, since the area of the light pattern is determined according to the light diffusion range of the reflector 400, the incident end faces S2 and S3 are formed larger than the direct light. Further, the reflectors 400 may have different light diffusion ranges, and the incidence planes S2 and S3 due to the reflected light may have different sizes. That is, the size of the incidence surface of the light 101 incident on the optical portion 302 can be determined according to the light diffusion range of the reflector 400. As the light diffusion range becomes wider, And as the light diffusion range is narrowed, the incident surface of the light 101 can be made smaller.

Fig. 25 is a view showing a light pattern formed by the lamp 21 for a vehicle shown in Figs. 21 to 23. Fig.

Referring to FIG. 25, each of the lenticular lenses 312, 322, 332, and 342 may form three light patterns R1, R2, and R3 having the shape of a line. Further, each light pattern may meet with a different light pattern at the adjacent boundary.

25 shows that three light patterns (R1, R2, R3) formed in each lenticular lens meet with different light patterns at the adjacent boundary. That is to say, a plurality of closed graphic forms in which the light reflected by the plurality of light sources 101 and the reflector 400 are transmitted through the plurality of lenticular lenses 312, 322, 332, and 342 to form lines can be formed. For this purpose, the shape of the adjacent boundary by each lenticular lens, the arrangement of the light source 101 and the reflector 400 can be appropriately determined.

The widths of the light patterns R1, R2, and R3 having a line shape can be determined by the size of the incidence surface of the light 101. The width of the light pattern becomes smaller as the incidence end face of the light 101 becomes smaller and the width of the light pattern becomes larger as the incident end face of the light 101 becomes larger.

Fig. 25 shows light patterns R1, R2, and R3 having different widths. This is because the light diffusion range of the reflector 400 corresponding to the light pattern R2 is larger than the light diffusion range of the reflector 400 corresponding to the light pattern R1 and the light diffusion range of the reflector 400 corresponding to the light pattern R3 Which is smaller than the light diffusion range.

26 to 28 are views showing another vehicle lamp according to still another embodiment of the present invention.

Referring to Figs. 26 to 28, the vehicular lamp 60 includes a first light irradiation portion 610, a second light irradiation portion 620, and an optical portion 630.

The first light irradiation unit 610 serves to irradiate the first light having a point shape. The lamp 60 for a vehicle according to another embodiment of the present invention may include at least one first light irradiation part 610. [ The light source 100 described above can serve as the first light irradiation unit 610. Since the light source 100 has been described above, a detailed description will be omitted.

The second light irradiation unit 620 serves to irradiate the linear second light. For this purpose, the second light irradiation unit 620 may include a light source 621 that emits light in a point shape, and a light diffusion unit 622 that converts the light into a linear shape by diffusing the light in a point shape.

The light diffusion portion 622 may be a lenticular lens having at least one diffusion lens. As the light of the light source 621 is transmitted through the light diffusing portion 622, a light pattern in the form of a line can be formed.

FIG. 29 shows that the light pattern L1 is formed by the second light irradiation portion 620. FIG. The light incident on the light diffusion portion 622 is diffused by the diffusion lens to form a light pattern L1 in the form of a line.

Referring again to FIGS. 26 to 28, the optical portion 630 can transmit at least one of the first light and the second light to form a light pattern. That is, the optical portion 630 can transmit only the first light, transmit only the second light, or transmit both the first and second lights, thereby forming a light pattern.

The optical portion 630 may include at least one lenticular lens. Thus, the optical portion 630 can transmit the first light or the second light to form a light pattern. That is, the optical portion 630 can transmit a point-like first light to form a linear light pattern or a linear second light to form a planar light pattern.

The first light irradiation unit 610 and the second light irradiation unit 620 that respectively irradiate the first light and the second light can be selectively operated. That is, only the first light irradiation portion 610 irradiates the first light, only the second light irradiation portion 620 emits the second light, or the first light irradiation portion 610 and the second light irradiation portion 620 simultaneously emit the first light It is possible to irradiate the light and the second light.

The vehicle lamp 60 according to another embodiment of the present invention may be the tail lamp of a vehicle (not shown). That is, the vehicle lamp 60 is capable of lighting a tail lamp or a brake lamp.

Accordingly, the first light irradiation unit 610 and the second light irradiation unit 620 can selectively irradiate the first light or the second light according to an operation such as a taillight operation or a brake operation. For example, in the taillight operation, the first light irradiating unit 610 may be operated, and the second light irradiating unit 620 may operate when the lamp is operated. Alternatively, in the taillight operation, the first light irradiating unit 620 may operate and the first light irradiating unit 610 may operate in the case of a brake operation or the like.

The distance between the optical portion 630 and the first light irradiation portion 610 may be shorter than the distance between the optical portion 630 and the second light irradiation portion 620. As the light irradiation units 610 and 620 are closer to the optical unit 630, light is incident on the optical unit 630 with an energy of high concentration.

In the present invention, the first light is used to form a linear light pattern (hereinafter referred to as a first light pattern), and the second light is used to form a planar light pattern 2 light pattern "). For example, the second light pattern may provide the same effect as the background image of the first light pattern. Therefore, it is preferable that the first light pattern is recognized more clearly and the second light pattern is recognized as being unclear as compared with the first light pattern.

Since the distance between the optical portion 630 and the first light irradiation portion 610 is smaller than the distance between the optical portion 630 and the second light irradiation portion 620, the first light pattern is relatively clearly recognized, and the second light pattern is relatively It can be perceived as unclear.

When the optical unit 630 and the light diffusing unit 622 are lenticular lenses, the optical axis of the optical unit 630 is set such that the long axis of the diffusing lens provided in the optical unit 630 and the long axis of the diffusing lens provided in the optical diffusing unit 622 are perpendicular to each other. The light diffusion portion 630 and the light diffusion portion 622 may be disposed. Accordingly, the light emitted from the light diffusing portion 622 is uniformly incident on the optical portion 630, so that a second light pattern having a uniform overall shape can be formed.

Although the above description has been made on the case where the second light irradiating unit 620 irradiates the linear second light, according to another embodiment of the present invention, the second light irradiating unit may irradiate the second light having a planar shape.

30 is a view showing a second light irradiation part according to another embodiment of the present invention.

Referring to FIG. 30, the second light irradiation unit 640 may include a light source 641 and a reflector 642.

The light source 641 serves to irradiate light. The function of the light source 641 is the same as or similar to the function of the light source 100 described above, and thus a detailed description thereof will be omitted. Light may be irradiated to the reflector 642, which may include a diffusive layer 643. Thus, the light irradiated to the reflector 642 can be reflected by the diffusive layer 643 and irradiated to the optical portion 630. In particular, since the light is reflected by the diffusing layer 643, the second light irradiating part 640 can form a planar light pattern FS1 as shown in Fig.

The planar light pattern FS1 formed by the second light irradiation portion 640 is incident on the optical portion 630 and the optical portion 630 diffuses the incident light to form a planar second light pattern .

32 is a view showing a second light irradiation part according to another embodiment of the present invention.

Referring to FIG. 32, the second light irradiation unit 650 may include a light source 651 and a light guide plate 652.

The light source 651 serves to irradiate light. The function of the light source 651 is the same as or similar to the function of the light source 100 described above, and thus a detailed description thereof will be omitted. The light can be irradiated by the light guide plate 652 to be light-on-plane. That is, the light guide plate 652 diffuses incident light internally to form a planar light pattern FS1.

The planar light pattern FS1 formed by the second light irradiation portion 650 is incident on the optical portion 630. The optical portion 630 diffuses the incident light to form a planar second light pattern .

33 is a view showing a light pattern formed by a lamp for a vehicle according to another embodiment of the present invention.

Referring to FIG. 33, the light pattern may include a first light pattern L2 and a second light pattern FS2.

The first light pattern L2 can be recognized relatively clearly and the second light pattern FS2 can be perceived relatively unclear. Thus, the second light pattern FS2 can provide the same effect as the background image of the first light pattern L2.

The first light pattern L2 and the second light pattern FS2 may serve as taillamps or brakes. For example, a first light pattern L2 may be formed when a taillight control signal is generated in the vehicle, and a second light pattern FS2 may be formed when a lighting control signal such as a braid is generated in the vehicle . Conversely, the second light pattern FS2 may be formed when a taillight control signal is generated in the vehicle, and the first light pattern L2 may be formed when a lighting control signal such as a brake is generated in the vehicle.

34 is a view illustrating a lamp for a vehicle according to another embodiment of the present invention.

34, the vehicle lamp 70 includes a light source 710 and an optical portion 720. [

The light source 710 serves to irradiate light. At least one light source 710 may be provided. When a plurality of light sources 710 are provided, the distance between each light source and the first lenticular lens 721 may be the same or different. The function of the light source 710 is the same as or similar to that of the light source 1000 described above, so a detailed description will be omitted.

The optical unit 720 transmits light of the light source 710 and forms a light pattern. For this, the optical portion 720 may include a first lenticular lens 721 and a second lenticular lens 722. [

The first lenticular lens 721 transmits the light from the light source 710 and the second lenticular lens 722 transmits the light emitted from the first lenticular lens 721.

The light from the light source 710 is transmitted through the first lenticular lens 721 and the second lenticular lens 722 and the light transmitted through the first lenticular lens 721 and the second lenticular lens 722 is transmitted through the light- A pattern can be formed. More specifically, a linear light pattern is formed as a point-like light pattern formed by the light source 710 is transmitted through the first lenticular lens 721. In addition, a planar light pattern can be formed as the linear light pattern is transmitted through the second lenticular lens 722.

The first lenticular lens 721 and the second lenticular lens 722 are disposed so that the long axes of the diffusion lenses provided respectively in the first lenticular lens 721 and the second lenticular lens 722 are not parallel to form a planar light pattern, May be disposed.

In the present invention, the shape of the light pattern is determined by the angle between the diffusion lenses provided in the first lenticular lens 721 and the second lenticular lens 722. For example, the shape of the light pattern includes a quadrangle. Here, each side constituting the quadrangle may be a curve, not a straight line.

In addition, the size of the light pattern can be determined by the distance between the first lenticular lens 721 and the second lenticular lens 722.

Hereinafter, the shape and size of the light pattern according to the arrangement relationship of the first lenticular lens 721 and the second lenticular lens 722 will be described in detail.

FIG. 35 is a view showing the arrangement relationship between the first lenticular lens and the second lenticular lens according to still another embodiment of the present invention.

Referring to FIG. 35, the first lenticular lens 721 and the second lenticular lens 722 may be arranged such that the angle? Between the diffusion lenses provided respectively form a predetermined angle.

For example, the predetermined angle may be formed between 10 degrees and 80 degrees, but is not limited thereto.

When the angle between the diffusion lenses provided in the first lenticular lens 721 and the second lenticular lens 722 is 0 degree, the light transmitted through the second lenticular lens 722 does not form a planar light pattern, Can be formed.

In addition, when the angle between the diffusing lenses provided in the first lenticular lens 721 and the second lenticular lens 722 is 90 degrees, the light transmitted through the second lenticular lens 722 can form a rectangular light pattern .

On the other hand, a light pattern having a unique shape with an angle of more than 0 degrees and only 90 degrees can be formed between the diffusing lenses provided in the first lenticular lens 721 and the second lenticular lens 722, respectively. In particular, when the angle is between 10 degrees and 80 degrees, the shape of the light pattern becomes clear, and the shape can be changed according to the angle.

FIGS. 36 and 37 are diagrams illustrating the formation of a light pattern by a vehicle lamp according to another embodiment of the present invention.

Referring to FIG. 36, the vehicle lamp 70 may form a light pattern H. As the light of the light source 710 is transmitted through the first lenticular lens 721, a linear light pattern is formed. As the linear light pattern is transmitted through the second lenticular lens 722, (H) is formed. As described above, the shape of the light pattern H may vary depending on the angle between the diffusing lenses provided in the first lenticular lens 721 and the second lenticular lens 722, respectively.

The first lenticular lens 721 and the second lenticular lens 722 may be disposed at predetermined distances. Here, the predetermined distance may be more than 0 mm and less than 60 mm, but is not limited thereto.

The sizes of the light patterns H1 and H2 can be changed according to the distances d1 and d2 between the first lenticular lens 721 and the second lenticular lens 722 as shown in FIG. That is, when the distance between the first lenticular lens 721 and the second lenticular lens 722 is short, the size of the light pattern H1 becomes small and the distance between the first lenticular lens 721 and the second lenticular lens 722 becomes The larger the size of the light pattern H2 is.

If the distance between the first lenticular lens 721 and the second lenticular lens 722 is short, a larger energy is concentrated and a light pattern is formed, so that the light pattern H1 has a relatively clear shape. On the contrary, when the distance between the first lenticular lens 721 and the second lenticular lens 722 is long, the energy is dispersed to form a light pattern, so that the light pattern H2 has a relatively unclear shape.

38 is a view illustrating a lamp for a vehicle according to another embodiment of the present invention.

Referring to FIG. 38, the vehicle lamp 80 includes a light source 810 and a light pattern forming unit 820.

The light source 810 serves to irradiate light. At least one light source 810 may be provided. The function of the light source 810 is the same as or similar to that of the light source 100 described above, and thus a detailed description thereof will be omitted.

The light pattern forming unit 820 transmits light of the light source 810 to form a plurality of light patterns. Particularly, the light pattern forming unit 820 can allow the light patterns of different images to be observed according to the viewing angle. As the viewing angle sequentially changes in a certain direction, the light patterns of different images can provide a continuous motion shape.

The light pattern forming unit 820 may include an image layer 821 and a lenticular lens 822. The image layer 821 may include a plurality of different images. As the light patterns of the plurality of images sequentially change, the observer can recognize the continuous motion shape.

The lenticular lens 822 disperses the light transmitted through the image layer 821 and forms a light pattern of a specific image among images different from each other at a specific angle.

FIG. 39 is a view showing that light patterns of different images are recognized according to an angle of a vehicle lamp according to another embodiment of the present invention.

39, fragment image groups 821a, 821b, and 821c may be disposed corresponding to the diffusing lenses 822a, 822b, and 822c constituting the lenticular lens 822, respectively.

Each of the different images described above may be divided into a plurality of fragment images. For example, the A image is divided into Aa, Ab, and Ac, the B image is divided into Ba, Bb, and Bc, and the C image can be divided into Ca, Cb, and Cc.

The plurality of fragment images Aa, Ab, Ac, Ba, Bb, Bc, Ca, Cb and Cc are arranged so as to correspond to the diffusing lenses 822a, 822b and 822c constituting the lenticular lens 822 Bb and Cb slice images are arranged in correspondence with one diffusing lens 822a forming a group 821a and the Ab, Bb and Cb slice images are grouped into one group 821a, And Bc and Cc pieces of images may be arranged corresponding to one diffusion lens 822c by forming a group 821c.

The image layer 821 may be formed on the back surface of the lenticular lens 822, and may be formed of a combination of such pieces of image segments 821a, 821b, and 821c. A group of engraved images 821a, 821b and 821c may be printed on the back surface of the lenticular lens 822 or an image layer 821 may be formed on the back surface of the lenticular lens 822 in the form of a separate image film.

The diffusion lenses 822a, 822b, and 822c can refract the incident light and emit the light. Here, the irradiation angle of the light to be emitted may vary depending on the position of the light incident on the back surface of the diffusion lenses 822a, 822b, and 822c. Accordingly, a piece image recognized according to the direction of the observer looking at the diffusion lenses 822a, 822b, and 822c can be changed. For example, when looking at the diffusing lens 822a where the group 821a of the Aa, Ba, and Ca engraved images are arranged on the back face, the light pattern of the image of the Aa, Ba, or Ca engraved image is recognized .

Such a light pattern of the sculptured image recognized according to the viewing direction can be applied to all diffuse lenses. Thus, the light pattern of the images of Aa, Ab, and Ac fragment images is simultaneously recognized by the observer at a specific position, and the light patterns of the Ba, Bb, and Bc fragment images are simultaneously recognized by the observer at other positions. Cb, Cc The light pattern of the sculptured image can be recognized at the same time.

Here, the light pattern of the Aa, Ab, Ac slice image means a light pattern in which the fragment images are connected to each other. That is, the light pattern PA of the above-described A image can be recognized by the observer. Similarly, depending on the viewing direction, the observer may recognize the light pattern PB of the B image or the light pattern PC of the C image.

Here, the A, B, and C images may be images that provide continuous motion shapes. That is, the observer can recognize the continuous motion shape by sequentially observing the light patterns (PA, PB, PC) of the images A, B, and C.

Although FIG. 39 shows that the light patterns PA, PB, and PC for three images are sequentially recognized, the number of sequentially recognized images may vary according to various embodiments of the present invention.

40 is a view showing an image according to an embodiment of the present invention.

In the present invention, different images included in the image layer 821 can determine the transmission pattern of light. That is, each image can transmit light in the form of a unique pattern.

Specifically, each of the different images 900 may include a high light intensity region 910 and a low light intensity region 920 according to the transmission pattern of light. The high luminous intensity region 910 is a region for relatively transmitting light of the light source and the low luminous intensity region 920 is a region for transmitting the light of the light source relatively less.

The high light intensity region 910 and the low light intensity region 920 can be determined according to the thickness of the image layer, whether or not the paint forming the image is applied, and the degree of application of the paint.

A specific region of the image layer may be formed thick and another region may be formed thin. Since the region formed thicker than the thinly formed region has a low light transmittance, the thinly formed region may be the high luminous intensity region 910 and the thickly formed region may be the low luminous intensity region 920. [

In addition, the area where the paint is applied in the image layer is the low light area 920, and the area where the paint is not applied may be the high light area 910. In addition, the region where the paint is relatively applied to the image layer is the low light region 920, and the region where the paint is applied relatively less may be the high light region 910. [

The image 900 can be determined according to the arrangement of the high luminous intensity region 910 and the low luminous intensity region 920 and the light transmittance.

Although the image 900 is composed of the high light intensity region 910 and the low light intensity region 920 in the above description, the light transmittance in the interval between the light transmittance of the high light intensity region 910 and the light transmittance of the low lightness region 920 is The provided light intensity region may be included in the image 900. For example, a sequential image may be provided in which the high light intensity region 910 changes to a low light intensity region 920, where the high light intensity region 910 changes to a low light intensity region 920 through the medium lightness region You can. Therefore, the high-intensity region 910 and the low-intensity region 920 are mainly described below, but the image 900 of the present invention does not consist only of the high-intensity region 910 and the low-intensity region 920.

41-44 illustrate a group of images providing motion shapes according to an embodiment of the present invention.

Referring to FIG. 41, different images constituting the image laser can provide continuous movement in accordance with a sequential change in size of the high light intensity area and the low light intensity area.

The initial image may include low intensity regions arranged side by side. Some of the low light intensity areas may gradually increase while others may gradually decrease while proceeding to subsequent images. As a part of the low luminous intensity area is reduced, the high luminous intensity area of the corresponding image area gradually increases.

As the angle of the observer looking at the lamp of the vehicle sequentially changes, the observer gradually increases part of the low luminosity area, the other part of the low luminosity area gradually decreases, and the high luminosity area of the reduced low luminosity area gradually increases It is possible to recognize a motion shape.

Referring to FIG. 42, different images constituting the image laser can provide continuous movement as at least one of the areas and positions of the high intensity area and the low intensity area are randomly changed.

The initial image may include a plurality of high luminous intensity regions having the form of a dot as a whole as a low luminous intensity region. The sizes of the points may be equal to or different from each other, and the light transmittances may be the same or different. In addition, the points may form a group to form a specific form. The low luminous intensity region may or may not transmit light at all. As a whole, the low light region forms the background of the image, and the high light region forms the foreground of the image.

At least one of the area and the position of each high brightness area may be randomly changed while proceeding to the subsequent image. For example, the area of a specific high luminous intensity area may be small or the high luminous intensity area at a specific point of the low luminous intensity area may move to another point of the low luminous intensity area.

Also, as described above, a plurality of high luminous intensity regions form a group to form a specific form, and the shape of the group may sequentially change as the luminous intensity progresses to a subsequent image.

As the angle of the observer looking at the lamp for the vehicle sequentially changes, the observer can perceive the gradually changing shape of the white spots in the dark background or the position. For example, an observer can perceive a motion shape such as a star flashing in the night sky.

On the other hand, Fig. 42 shows that the low light area forms the background of the image and the high light area forms the foreground of the image. Conversely, the high light area forms the background of the image, .

Referring to FIG. 43, different images constituting the image laser can provide continuous motion as the high light intensity region sequentially changes to the low light intensity region, or the low light intensity region sequentially changes to the high light intensity region.

The initial image may include a plurality of low luminous intensity regions (hereinafter referred to as a second low luminous intensity region) having a polygonal shape as a whole as a low luminous intensity region (hereinafter referred to as a first luminous intensity region). And the second low luminous intensity region may be arranged by forming a certain pattern on the first low luminous intensity region. For example, the second low luminous intensity region may be arranged on the first low luminous intensity region in a lattice form. Here, the second low luminous intensity region may have a higher light transmittance than the first low luminous intensity region.

The second low light intensity region gradually increases in size, and the first low light intensity region is generated in the second low light intensity region, thereby increasing the size. Then, the second low luminous intensity region can gradually change to the high luminous intensity region.

As the angle of the observer looking at the lamp for the vehicle sequentially changes, the observer can recognize the motion shape in which the low luminous intensity region changes to the high luminous intensity region.

On the other hand, FIG. 43 shows that the initial low-light region and the second low-light region are included in the initial image, but the initial image may include the first high light region and the second high light region. Here, the second high light intensity region may have a lower light transmittance than the first high light intensity region.

Thus, the second high light intensity region gradually increases in size, the first high light intensity region is generated in the second high light intensity region, the size gradually increases, and the second high light intensity region gradually changes to the low light intensity region have.

Referring to FIG. 44, different images constituting the image laser can provide continuous movement as at least one of the area and the position of the high luminous intensity area and the low luminous intensity area sequentially changes.

The initial image may include a plurality of high luminous intensity regions having a line shape as a whole as a low luminous intensity region. The thicknesses of the lines may be equal to or different from each other, and their light transmittances may be the same or different.

Each line may change its shape sequentially as it proceeds to the subsequent image. For example, a straight line may change to a curve, or a line thickness may change. Or, the light transmittance of a line may change.

The low luminous intensity region may or may not transmit light at all. As a whole, the low light region forms the background of the image, and the high light region forms the foreground of the image.

A plurality of high luminous intensity regions can form a specific shape by forming a group. As the image is advanced to a subsequent image, the shape of the entire group may change sequentially.

As the angle of the observer looking at the lamp for the vehicle sequentially changes, the observer can perceive the motion shape in which the size or position of the white lines changes gradually in the dark background. For example, an observer can recognize a motion shape such as a wave.

44 shows that the low light area forms the background of the image and the high light area forms the foreground of the image whereas the high light area forms the background of the image and the low light area is the foreground of the image .

Figs. 41 to 44 show that six images sequentially change. Accordingly, six piece images can be correspondingly arranged in one diffusion lens. The observer can recognize the light pattern of the specific piece image among the six piece images according to the angle at which the vehicle lamp is viewed.

At this time, a light pattern for a plurality of fragment images corresponding to a plurality of consecutive diffusion lenses can be simultaneously recognized by an observer, wherein the light pattern for a plurality of fragment images is a light pattern of a specific image among the six images Can respond.

Therefore, according to another embodiment of the present invention, the number of sequentially changing images may be varied, and accordingly, the number of pieces of images arranged corresponding to the diffusion lens may vary.

The foregoing has described that a plurality of images sequentially change. For example, if the image layer contains 6 images, the image may change in the order of 1-> 2-> 3-> 4-> 5-> 6 depending on the angle of the observer viewing the vehicle lamp. Here, when the angle of the observer looking at the lamp for the vehicle exceeds the angle at which the sixth image is viewed, it returns to the first image. That is, when the angle of the observer looking at the lamp for the vehicle is continuously changed, the image is repeated at 1-> 2-> 3-> 4-> 5-> 6.

There may be continuity between adjacent images, but there may not be continuity between other images. For example, there may be continuity between the first image and the second image, but there may be no continuity between the first image and the third image. Thus, if a light pattern for the second image is recognized after the light pattern for the first image is recognized, a movement pattern is provided, but after the light pattern for the first image is recognized, Once recognized, a disconnected motion shape may be provided.

Likewise, if the light pattern for the first image is recognized after the light pattern for the sixth image is recognized, a disconnected motion shape that is not continuous to each other can be provided.

Therefore, the vehicle lamp according to the embodiment of the present invention can provide a continuous motion shape even if the observer's angle continuously changes.

FIG. 45 is a view showing that a light pattern of a continuous image is recognized according to an angle at which a vehicle lamp according to another embodiment of the present invention is viewed.

As the image layer 821 in Fig. 38 is replaced with the image layer 823 in Fig. 45, the light pattern of the continuous image can be recognized according to the angle at which the vehicle lamp 80 is viewed.

45, fragment image groups 823a, 823b, and 823c may be disposed corresponding to the diffusion lenses 822a, 822b, and 822c constituting the lenticular lens 822. [

Each of the different images described above may be divided into a plurality of fragment images. For example, the A image is divided into Aa, Ab, and Ac, the B image is divided into Ba, Bb, and Bc, and the C image can be divided into Ca, Cb, and Cc.

The plurality of sculptured images may be included in the image layer 823 such that the plurality of sculptured images are arranged corresponding to the different diffusion lenses 821a, 821b, and 821c constituting the lenticular lens 822. [ That is, images of Aa, Ba, and Ca slices form a group 823a and are arranged corresponding to one diffusion lens 822a, and images of Ab, Bb, and Cb pieces form a group 823b, 822b, and the Ac, Bc, and Cc engraved images may be arranged corresponding to one diffusion lens 822c by forming a group 823c.

Here, as the viewing angle changes sequentially in a specific direction, the light patterns of different images can be converted to a specific switching order (hereinafter, referred to as a first switching order). Thus, as the light patterns of different images are switched, a continuous movement shape according to the first switching order can be provided. For this purpose, the plurality of pieces of image Aa, Ab, Ac, Ba, Bb, Bc, Ca, Cb, Cc may be arranged corresponding to the diffusing lens so as to provide a continuous movement shape according to the first switching order. That is, the fragment image is arranged in the order of Aa-> Ba-> Ca, the fragment image is arranged in the order of Ab-> Bb-> Cb, and the fragment image is arranged in the order of Ac-> Bc-> Cc .

Here, it can be understood that the position of the observer looking at the on-vehicle lamp 80 changes in a specific direction when the viewing angle sequentially changes in a specific direction. That is, when the observer looking at the vehicle lamp 80 from the front or rear of the vehicle moves in the left direction or the right direction, the viewing angle changes sequentially in the corresponding direction. Therefore, the fact that the viewing angle sequentially changes in a specific direction means that the observer continuously moves to the left or right, and does not switch the direction. Hereinafter, the specific direction of the angle described above is referred to as an angle forward direction.

When the viewing angle exceeds the threshold value and sequentially changes in the forward direction of the angle, the light patterns of different images can be switched in the opposite order of the first switching order (hereinafter referred to as a second switching order). Thus, a continuous movement shape according to the second switching order is provided.

For this purpose, the plurality of pieces of image Aa, Ab, Ac, Ba, Bb, Bc, Ca, Cb, and Cc may be arranged corresponding to the diffusion lens so as to provide a continuous movement shape according to the second conversion order. That is, after the fragment image of Ca, the fragment image is arranged in the order of Ba-> Aa, the fragment image is arranged in the order of Bb- > Ab after the fragment image of Cb, The fragment image is arranged in the order of.

As a result, in each diffusing lens, a sculptured image group 823a having the order of Aa- > Ba- > Ca- > Ba- > Aa, a sculptured image group having a sequence of Ab- > Bb- > Cb- > Bb- & And a fragment image group 823c having an order of Ab- > Bb- > Cb- > Bb- > Ab.

The image layer 823 is composed of a combination of these pieces of sculpted image groups 823a, 823b and 823c and may be provided on the back of the lenticular lens 8220. Sculptured image groups 823a, 823b, 823c may be printed or the image layer 823 may be implemented in the form of a separate image film and attached to the back of the lenticular lens 822. [

The diffusion lenses 822a, 822b, and 822c can refract the incident light and emit the light. The functions of the diffusing lenses 822a, 822b, and 822c have been described above with reference to FIG. 39, so a detailed description thereof will be omitted.

The light pattern (PA) of the image of Aa, Ab, and Ac fragments is simultaneously recognized by the observer at a specific position, and the light pattern (PB) of the image of Ba, Bb, and Bc fragments is simultaneously recognized by the observer at another position, The light pattern (PC) of the images of Ca, Cb, and Cc pieces can be simultaneously recognized by the observer.

Aa, Ab, Ac The light pattern of an engraved image means a light pattern in which engraved images are connected to each other. That is, the light pattern PA of the above-described A image can be recognized by the observer. Similarly, depending on the viewing direction, the observer may recognize the light pattern PB of the B image or the light pattern PC of the C image.

The A, B, and C images may be images that provide a continuous motion shape. That is, the observer can sequentially recognize the motion shape by sequentially observing the light patterns (PA, PB, PC) of the images A, B, and C. Also, as the position of the observer continuously changes, the light patterns PB and PA of the B- > A image can be sequentially recognized after the light pattern PC of the C image.

Thus, it is possible to provide a seamless movement pattern between the light pattern immediately before the viewing angle exceeds the threshold value and the light pattern immediately after the viewing angle exceeds the threshold value. For example, the light pattern immediately before the viewing angle exceeds the threshold value is PC, and the light pattern immediately after the viewing angle exceeds the threshold value may be PB, and the observer may continuously change the position in a specific direction The light pattern of the image having continuity can be recognized.

Although FIG. 45 illustrates that the light patterns for three images are sequentially recognized, the number of images sequentially recognized according to various embodiments of the present invention may vary.

46 is a diagram illustrating a group of images providing a continuous motion shape according to an embodiment of the present invention.

46, the images Im1, Im2, Im3, Im4, Im5, and Im6 provided to the observer change sequentially as the angle of the observer looking at the vehicle lamp 80 changes.

As the angle of the observer looking at the lamp for the vehicle sequentially changes, the light patterns of different images can provide a continuous movement shape having a specific traveling direction. That is, images are provided in the order Im1-> Im2-> Im3-> Im4-> Im5-> Im6.

In addition, when the angle of the observer looking at the lamp for the vehicle changes sequentially beyond the threshold value, the light pattern of different images can provide a continuous movement shape having a direction opposite to the specific traveling direction. That is, when the observer moves in the existing direction and the observation angle is continuously changed in a state in which the image is provided in the order of Im5-> Im6, the image is displayed in order of Im6-> Im5-> Im4-> Im3-> Im2-> Im1 Is provided.

Here, Im1 to Im6 may be one of the image groups shown in Figs. That is, continuity exists between adjacent images.

With this cyclical change of the image, the observer can recognize the light pattern of the continuous image regardless of the angle of the observer looking at the lamp for the vehicle.

47 is a view illustrating a lamp for a vehicle according to another embodiment of the present invention.

Referring to FIG. 47, a vehicle lamp 90 includes a light source 1010 and a light pattern forming unit 1020.

The light source 1010 serves to irradiate light. At least one light source 1010 may be provided. Since the function of the light source 1010 is the same as or similar to that of the light source 100 described above, a detailed description thereof will be omitted.

The light pattern forming unit 1020 transmits light of the light source 1010 and forms a light pattern of different images according to an angle of view. In particular, as the viewing angles change sequentially, the light patterns of different images can provide a continuous motion shape.

The optical pattern forming unit 1020 may include an image layer 1021 and a lenticular lens 1022. The image layer 1021 may include a plurality of different images. The plurality of different images may be one of the image groups shown in Figs. As the light patterns of the plurality of images sequentially change, the observer can recognize the continuous motion shape.

The lenticular lens 1022 serves to disperse the light transmitted through the image layer 1021 to form a light pattern of a specific image among images different from each other at a specific angle looking at the lamp 90 for a vehicle.

The vehicle lamp 90 according to the embodiment of the present invention may be a tail lamp. Thus, the vehicle lamp 90 may be provided on both sides of the rear of the vehicle. Further, the vehicular lamp 90 may include a curvature according to the shape of both sides of the rear end of the vehicle.

On the other hand, when looking at the vehicle lamp from the rear of the vehicle, the size of the light pattern of each image may vary depending on the curvature. That is, although the light pattern of a portion without a curvature is recognized as a normal size, a light pattern of a portion having a curvature can be recognized as a size smaller than a normal size. This allows the observer to perceive a light pattern of the entirely distorted image.

Accordingly, the optical pattern forming unit 1020 according to the embodiment of the present invention may include a curvature region having a curvature. The size of the optical pattern formed corresponding to the curvature region may be determined by the size of a light pattern formed corresponding to the planar region, May be the same or similar. Thereby, the observer can recognize the light pattern of the image having the entirely normal ratio in which the size of the curvature portion is compensated.

48 is a view showing a light pattern forming unit according to another embodiment of the present invention.

Referring to FIG. 48, the size of the curvature region included in the optical pattern forming unit 1020 and the size of the image region corresponding to the curvature region among the regions of the different images included in the image layer may be determined by the curvature .

That is, the larger the curvature, the larger the curvature area and the image area can be formed as compared with the straight line section.

The diffusion lens 1022b, 1022c, 1022d of the curvature section and the image layer piece 1021b, 1021c, 1021d of the curvature section, as compared with the diffusion lens 1022a and the image layer piece 1021a of the straight section, The size can be made larger. Also, in the curvature section, the diffusion lenses 1022, 1022c, 1022d and the image layer pieces 1021b, 1021c, 1021d can be formed to have a larger size as the magnitude of the curvature increases. That is, since the curvature increases from the right side to the left side in FIG. 48, the sizes of the diffusion lenses 1022b, 1022c, and 1022d and the image layer pieces 1021b, 1021c, and 1021d increase.

47 and 48 illustrate that the image layer pieces 1021b, 1021c, and 1021d of the curvature region are expanded, but they may be reduced according to the direction of the curvature.

FIGS. 49 to 52 are diagrams showing changes in the size of the engraved image according to the embodiment of the present invention. FIG.

As described above, each of the different images may be divided into a plurality of slice images, and a plurality of slice images may be included in the image layer such that they are arranged corresponding to different diffusion lenses constituting the lenticular lens.

49 to 52 show that two image pieces A and B are included in the image layer IL.

Referring to Figs. 49 and 50, when the curvature region is formed in a direction away from the observer, the sculpture image of the curvature region can be enlarged.

As shown, the engraved image B is bent in a direction away from the observer. Hereinafter, the warped piece image B is referred to as a piece image B1. As described above, the sculptured image B1 can be included in the curvature region of the light pattern forming portion 1020. [

If the lengths of the sculptured image B and the sculptured image B1 are the same, the sizes of the light patterns recognized by the observer may be different. That is, the light pattern LB by the sculptured image B can be largely recognized as compared with the light pattern LB1 by the sculptured image B1. The size of the recognized light pattern can be recognized differently when the sculptured image exists in the planar region of the light pattern forming portion 1020 and when the sculptured image exists in the curvature region of the light pattern forming portion 1020. [

As described above, the plurality of piece images may include a first piece image included in the planar region of the light pattern forming portion 1020 and a second piece image included in the curvature region of the light pattern forming portion 1020, The size of the second piece image can be determined such that the size of the recognized light pattern for the first piece image and the size of the recognized light pattern for the second piece image are the same. The size of the second piece image can be reduced or enlarged relative to the first piece image so that the size of the light pattern recognized for the first piece image and the size of the light pattern recognized for the second piece image are equal.

50 shows that the size of the fragment image B1 is expanded. If the curvature region is formed in a direction away from the observer, the sculptural image B1 can be enlarged. Accordingly, the observer can recognize the same size of the light pattern LB by the sculptured image B and the size of the light pattern LB1 by the sculptured image B1.

Referring to Figs. 51 and 52, when the curvature region is formed in a direction approaching to the observer, the sculpture image of the curvature region can be reduced.

As shown, the sculptured image B is bent in the direction toward the observer. Hereinafter, the warped piece image B is referred to as a piece image B2. As described above, the engraved image B2 may be included in the curvature region of the light pattern forming portion 1020. [

If the lengths of the sculptured image B and the sculptured image B2 are the same, the size of the light pattern recognized by the observer may be different. That is, the light pattern LB by the sculptured image B can be recognized to be smaller than the light pattern LB2 by the sculptured image B2. The size of the recognized light pattern can be recognized differently when the sculptured image exists in the planar region of the light pattern forming portion 1020 and when the sculptured image exists in the curvature region of the light pattern forming portion 1020. [

As described above, the plurality of piece images may include a first piece image included in the planar region of the light pattern forming portion 1020 and a second piece image included in the curvature region of the light pattern forming portion 1020, The size of the second piece image can be determined such that the size of the recognized light pattern for the first piece image and the size of the recognized light pattern for the second piece image are the same. The size of the second piece image can be reduced or enlarged relative to the first piece image so that the size of the light pattern recognized for the first piece image and the size of the light pattern recognized for the second piece image are equal.

Fig. 52 shows that the size of the piece image B2 is reduced. When the curvature region is formed in a direction approaching to the observer, the engraved image B2 can be reduced. Accordingly, the observer can recognize the same size of the light pattern LB by the sculptured image B and the size of the light pattern LB2 by the sculptured image B2.
