Hereinafter, the present invention will be described with reference to the drawings for explaining a vehicle lamp according to embodiments 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 for reflecting light may be provided around the light source 100.

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. The optical pattern of the light source 100 having the shape of a dot is diffused by the diffusion lens 210 of the lenticular lens 200 to form a straight light pattern L and is recognized by the observer. The observer can recognize one light pattern L having a straight line shape in 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 straight line light pattern recognized by the observer is the position F which is not a surface of the lenticular lens 200 but is spaced apart from the lenticular lens 200 by a certain distance. That is, it can be understood that the lenticular lens 200 forms a light pattern by transmitting light.

As described above, a light pattern L of a straight 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 is a view showing a light pattern 110 and a light pattern forming unit 120 of a lamp 30 for a vehicle according to another embodiment of the present invention.

The light source 110 serves to irradiate light. At least one light source 110 may be provided. Since the function of the light source 110 is the same as or similar to that of the light source 100 described above, a detailed description will be omitted.

The light pattern forming unit 120 transmits light of the light source 110 and forms a plurality of light patterns. Particularly, the light pattern forming unit 120 may allow light patterns of different images to be observed depending on 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 120 may include an image layer 121 and a lenticular lens 122. The image layer 121 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 122 disperses the light transmitted through the image layer 121 and forms a light pattern of a specific image among images different from each other at a specific angle.

FIG. 6 is a diagram illustrating that light patterns of different images are recognized according to an angle of a vehicle lamp according to another embodiment of the present invention.

6, fragment image groups 121a, 121b and 121c may be arranged corresponding to the diffusion lenses 122a, 122b and 122c constituting the lenticular lens 122, 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 122a, 122b and 122c constituting the lenticular lens 122 And may be included in the image layer 121. That is, images of Aa, Ba, and Ca slices form a group 821a and are arranged corresponding to one diffusion lens 822a, and images of Ab, Bb, and Cb pieces form a group 821b, 822b, and the Ac, Bc, and Cc engraved images may be arranged corresponding to one diffusion lens 822c by forming a group 821c.

The image layer 121 may be provided on the back surface of the lenticular lens 122, and may be formed of a combination of the segmented image groups 121a, 121b, and 121c. 121b and 121c may be printed on the back surface of the lenticular lens 122 or the image layer 821 may be formed on the back surface of the lenticular lens 122 in the form of a separate image film.

The diffusion lenses 122a, 122b, and 122c 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 122a, 122b, and 122c. Accordingly, the piece image recognized according to the direction of the observer looking at the diffusion lenses 122a, 122b, and 122c can be changed. For example, when looking at the diffusion lens 122a having the group 121a of the Aa, Ba, and Ca engraved images 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. 6 illustrates 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.

7 is a diagram illustrating an image according to an embodiment of the present invention.

In the present invention, different images included in the image layer 121 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 300 may include a high light intensity region 310 and a low light intensity region 320 according to the transmission pattern of light. The high luminous intensity region 310 is a region for relatively transmitting light of a light source and the low luminous intensity region 320 is a region for transmitting light of a light source relatively lightly.

The high light intensity region 310 and the low light intensity region 320 may be determined according to at least one of the thickness of the image layer, whether or not the paint forming the image is coated, and the coating degree 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 310 and the thickly formed region may be the low luminous intensity region 220.

The area of the image layer to which the paint is applied is the low light area 320 and the area to which the paint is not applied may be the high light area 310. [ In addition, the area where the paint is applied relatively to the image layer is the low light area 320, and the area where the paint is applied relatively less may be the high light area 310. [

The image 200 can be determined according to the arrangement of the high light intensity region 310 and the low light intensity region 320 and the light transmittance.

Although the image 300 includes the high light intensity region 310 and the low light intensity region 320, the light transmittance in the interval between the light transmittance of the high light intensity region 310 and the light transmittance of the low light intensity region 320 is The lightness region provided may be included in the image 300. For example, a sequential image may be provided in which the high light intensity region 310 changes to a low light intensity region 320, wherein the high light intensity region 310 changes to a low light intensity region 320 through the lightness degree region You can. Therefore, the high lightness area 310 and the low light area 320 are mainly described below, but the image 300 of the present invention does not consist of the high light area 310 and the low light area 320 alone.

8 to 9 are diagrams illustrating groups of images providing motion shapes according to an embodiment of the present invention.

Referring to FIG. 9, the different images constituting the image layer can provide continuous movement according to sequential size change of the high luminous intensity area and the low luminous 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. 9, different images constituting the image layer can provide continuous motion as at least one of the area and the position of the high luminous intensity area and the low luminous intensity area is 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. 9 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. 10, different images constituting the image layer can provide continuous motion as the high luminous intensity region sequentially changes to the low luminous intensity region or the low luminous intensity region sequentially changes to the high luminous 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.

Meanwhile, FIG. 10 shows that the initial low-lightness region and the second low-lightness region are included in the initial image, but the initial image may include the first high-lightness region and the second high-lightness 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. 11, different images constituting the image layer can provide continuous motion 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.

On the other hand, Fig. 11 shows that the low luminosity area forms the background of the image and the high luminosity area forms the foreground of the image, while the high luminosity area forms the background of the image, .

Figures 8 to 11 illustrate sequential changes in six images. 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. 12 is a view showing that a light pattern of a continuous image is recognized according to an angle of a vehicle lamp according to another embodiment of the present invention.

As the image layer 121 of FIG. 5 is replaced with the image layer 123 of FIG. 12, the light pattern of the continuous image can be recognized according to the angle at which the vehicle lamp 20 is viewed.

12, pieces of engraved images 123a, 123b, and 123c may be disposed corresponding to the diffusing lenses 122a, 122b, and 122c constituting the lenticular lens 122, 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 sculptured images may be included in the image layer 823 such that the plurality of sculptured images are arranged corresponding to the diffusing lenses 121a, 121b and 121c constituting the lenticular lens 122. [ That is, images of Aa, Ba and Ca slices form a group 123a and are arranged corresponding to one diffusion lens 122a, and images of Ab, Bb and Cb pieces form a group 123b, And Bc and Cc fragment images may be arranged corresponding to one diffusing lens 122c by forming a group 123c.

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, each diffusing lens has a sculptured image group (123a) having a sequence of Aa -> Ba -> Ca -> Ba -> Aa, a sculptured image group having a sequence of Ab -> Bb -> Cb -> Bb -> Ab (123b) and a fragment image group 123c having the order of Ab -> Bb -> Cb -> Bb -> Ab.

The image layer 123 may be formed on the back surface of the lenticular lens 122, and may be formed of a combination of these pieces of image segments 123a, 123b, and 123c. A group of engraved images 123a, 123b and 123c may be printed on the back surface of the lenticular lens 822 or an image layer 123 may be formed on the back surface of the lenticular lens 122 in the form of a separate image film.

The diffusion lenses 122a, 122b, and 122c can refract the incident light and emit the light. The functions of the diffusing lenses 122a, 122b, and 122c have been described above with reference to FIG. 6, 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.

13 is a view showing a continuous image light pattern recognized according to an angle at which the lamp for a vehicle is viewed.

Referring to FIG. 13, the lenticular lens 140 has the same function as the lenticular lens 122 described above. The diffuser lenses 142a, 142b, 142c, and 142d are included in the lenticular lens 140 so as to be arranged in a warped shape, and the diffusion lenses 142a, 142b, 142c, 143b, 143c, and 143d are arranged in the image layer 143 in correspondence with the images 142a, 142b, 142c, and 142d.

B ₂ , B ₂ , C ₂ , D ₂ , B ₁ , B ₁ , B ₁ , C ₁ , D ₁ , and E ₁ are formed corresponding to one diffusion lens 142 a, E ₂ slice images form a group 143b corresponding to one diffusion lens 142b and A ₃ , B ₃ , C ₃ , D ₃ and E ₃ slice images form a group 143c, A ₄ , B ₄ , C ₄ , D ₄ and E ₄ pieces of images may be arranged corresponding to one diffusion lens 142c forming the group 143d .

As in the case of the lenticular lens 122 of FIG. 12 described above, the angle of view changes sequentially in a specific direction, so that light patterns of different images can be transferred.

Since the diffusing lenses 142a, 142b, 142c and 142d of the lenticular lens 140 are bent and arranged by the curvature, when the viewing angle of the lenticular lens 140 changes sequentially in a specific direction, The position where the light pattern of the other image is formed is not the same as when the lenticular lens is arranged flat.

In other words, when the lenticular lens 140 is formed without bending like the lenticular lens 122 described above, when the angle of looking at the lenticular lens sequentially changes in a specific direction, at a specific point, A ₁ , A ₂ , A _3, molding the image of a ₄ is connected may be a light pattern of the a image recognition, the lenticular lens 140 is so formed standing bent according to the curvature of the above certain point a _2, a _2, C _3, C ₄ The light pattern to which the sculptured image of the desired A-image is attached may be recognized, so that the light pattern of the desired A-image may not be formed.

Therefore, when the lenticular lens 140 is bent and formed as described above, there is a need to change the order of the engraved images arranged in the image layer.
