Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of priority to Korean Patent Application No. 10-2021-0152500, filed in the Korean Intellectual Property Office on Nov. 8, 2021, the entire content of which is incorporated herein by reference. 
     BACKGROUND 
     1. Technical Field 
     The present disclosure relates to a lamp for a vehicle, and more particularly, to a lamp for a vehicle that may implement a three-dimensional image. 
     2. Discussion of Related Art 
     In general, a vehicle includes various kinds of lamps having a lighting function for allowing a user to easily identify an object located around a vehicle during nighttime driving and a signal function for informing other vehicles or road users of a driving state of the vehicle. For example, turn signal lamps, tail lamps, brake lamps, side markers, and the like are signal lamps mainly for signal functions. 
     To secure a design distinction and an aesthetic aspect of a lamp for a vehicle, various technologies for differentiating an image of a signal lamp are applied. According to a conventional technology, to implement a three-dimensional lighting image of a lamp for a vehicle, methods that use a lenticular lens, in which a film is laminated, a hologram technology, an optical fiber, a bezel, and the like are used. 
     However, the conventional technology requires a separate light source and a separate medium, such as a lens film, and thus manufacturing costs and the number of components may increase. Accordingly, it is necessary to improve a technology for enhancing a product value of a lamp and decreasing material costs and the number of components by implementing a three-dimensional lighting image. 
     SUMMARY 
     The present disclosure has been made to solve the above-mentioned problems occurring in the prior art while advantages achieved by the prior art are maintained intact.

FIG.  14    is a lamp for a vehicle according to an embodiment of the present disclosure, and is a view illustrating an example, in which a plurality of light source parts are provided. 
     A lamp  10  for a vehicle according to the present disclosure is a lamp for implementing a lighting image having a 3D feeling, and for example, may be a lamp, such as a turn signal lamp, which performs a signal function. However, the lamp  10  for a vehicle according to the present disclosure is not limited thereto, and may be used to implement a 3D image in various kinds of lamps  10  for a vehicle. 
     Referring to  FIGS.  1  to  14   , the lamp  10  for a vehicle according to an embodiment of the present disclosure includes a light source part  100  and a lens part  200 . 
     The light source part  100  may be configured to irradiate light, and various elements or devices, which may emit light, may be used. The light source part  100  may include a light source  110  that generates light, and for example, the light source  110  may be a light emitting diode (LED). 
     The lens part  200  is configured to output light input from the light source part  100  in a forward direction of the lens part  200  toward a front side of the lens part  200 , and has a 3D pattern  220  having a specific pattern shape. 
     Furthermore, the lens part  200  is configured to output the light input from the light source part  100  to the front side when the light reaches the 3D pattern  220 . Furthermore, the 3D pattern  220  may be patterned such that a lighting image generated by the light output to a front side of the lens part  200  is implemented as or converted to a 3D image. 
     In detail, the present disclosure is adapted to implement a lighting image of a 3D shape by irradiating light to the lens part  200 , in which the 3D pattern  220  is patterned, and a 3D image may be implemented by the 3D pattern  220  formed in the lens part  200  itself without using a separate special light source, lens, or film. 
     The light irradiated by the light source part  100  and input to the lens part  200  may travel while totally reflected in an interior of the lens part  200 , and then may be output to the front side in an area, in which the 3D pattern  220  is formed (i.e., a 3D pattern area), while not totally reflected further when it reaches the 3D pattern  220 . Then, the light that reached the 3D pattern  220  may be output to the rear side as well as to the front side of the lens part  200 . 
     The lens part  200  may include a lens body  210  formed to be flat or curved. Furthermore, the 3D pattern  220  may be patterned in a design that may implement a 3D feeling on a surface or in an interior of the lens body  210 . 
     For example, as in an example illustrated in  FIG.  1   , the 3D pattern  220  may be designed such that a 3D feeling may be expressed by a plurality of circles when it is viewed from the front side. In detail, the 3D pattern  220  may include a first concentric circle  222  having a concentric relationship, a second concentric circle  223  having a size that is smaller than that of the first concentric circle  222 , and one or more inner circles  224  located in an interior of the second concentric circle  223  and inclined to one side. Furthermore, the 3D pattern  220  may include a plurality of first curved parts  225  that are located in an interior of the second concentric circle  223  and connect two points of the second concentric circle  223 , and a plurality of second curved parts  226  that extend from one point of the second concentric circle  223  and extend to an outside of the second concentric circle  223  while crossing an interior of the second concentric circle  223 . Then, the plurality of first curved parts  225  may have different curvatures to be formed to have a 3D feeling, and the plurality of second curved parts  226  may be formed to become farther away from each other as they go to an outside of the second concentric circle  223  to have a 3D feeling. However, the 3D pattern  220  according to the present disclosure is not limited to the embodiment illustrated in  FIG.  1   , and a design having a 3D feeling may have various shapes. 
     Furthermore, for example, referring to  FIGS.  2 A,  2 B, and  3   , the 3D pattern  220  may be configured to be designed in a shape having at least one vanishing point when viewed in a rearward direction of the lens part  200  from the front side of the lens part  200 , and to give or provide a 3D perspective to the lighting image that is generated as the light is output from the lens part  200 . The vanishing point refers to a point, at which lines meet each other when extension lines of an object is drawn by projecting the object in a picture or a blueprint. The perspective method using a vanishing point is used to express a 3D expression on a 2-dimensional (2D) plane. 
     The present disclosure may allow the lighting image to be implemented as a 3D image of a 3D shape when the lighting is made through the 3D pattern  220  formed in the lens part  200  of a specific thickness, by forming the 3D pattern  220  designed by using the vanishing point and the perspective method in the lens body  210 . As an example, for the 3D pattern illustrated in  FIG.  2 A , each of five hexagons is designed by using a one-point perspective technique having one vanishing point. Furthermore, for the 3D pattern illustrated in  FIG.  2 B , one hexagon is designed by using a 3-point perspective technique having three vanishing points P 1 , P 2 , and P 3 . 
     The lamp  10  for a vehicle according to the present disclosure is similar to a general lens when it is not lighted and no 3D feeling is felt, but may implement a 3D lighting image by using the light output through the 3D pattern  220  when it is lighted. That is, the present disclosure may be implemented by a hidden lighting lamp. 
     The lens part  200  may include the lens body  210 , an input surface  230 , a front surface  250 , and a rear surface  240 . 
     The lens body  210  constitutes a body of the lens part  200  as described above, and may have a specific thickness and may have a shape that is flat (see  FIG.  4   ) or includes a surface curved forwards or rearwards. The lens body  210  may be formed of a transparent material, and for example, may be formed of a material, such as plastic or glass. However, a material of the lens body  210  is not limited thereto, and may be variously modified as long as it is a material that may transmit light. 
     The input surface  230  may be formed on one side of the lens body  210  and the light may be input from the light source part  100 . For example, the input surface  230  may be formed on a side surface that is a surface that is perpendicular to a direction that faces the front side of the lens body  210 . Furthermore, the light source part  100  may be disposed in a lateral direction of the lens body  210  to irradiate the light toward the input surface  230 . Furthermore, the light source part  100  may include a plurality of light sources  110 , and the plurality of light sources  110  may be disposed to be spaced apart from each other along a peripheral circumference of the lens body  210 . In this case, the light may be uniformly irradiated from the light source part  100  toward the lens part  200 . 
     The front surface  250  may be formed on a front side of the lens body  210 . Furthermore, the rear surface  240  may be formed on a rear side of the lens body  210 . The front surface  250  is a surface that faces a direction, in which the light is irradiated through the lamp  10  for a vehicle, and a 3D lighting image may be formed through the light irradiated through the front surface  250 . Furthermore, the rear surface  240  is a surface that faces an opposite direction to the front surface  250 . 
     Here, the 3D pattern  220  may be formed on at least one of an interior of the lens body  210 , the front surface  250 , and the rear surface  240 . 
     The lens part  200  may be configured such that the light input to the lens body  210  is output to the front side toward the front surface  250  in an area, in which the 3D pattern  220  is formed. Furthermore, the lens part  200  may be configured to totally reflect the light in an area of the front surface  250  and the rear surface  240 , other than the area, in which the 3D pattern  220  is formed. 
     In detail, the lens part  200  uses a total reflection principle, and the light input from the light source part  100  to the lens part  200  may travel while totally reflected in the interior of the lens part  200  and may output forwards and rearwards while not being totally reflected further in the area, in which the 3D pattern  220  is formed. That is, the light may be output forwards or rearwards, and here, when the light that faces the rear side may be classified into light output through the rear surface  240  and light that is reflected by the rear surface  240  and faces the front side again. Then, by the light that is directly output to the front side and the light that is output to the front side after being reflected by the rear surface  240 , among the light that reached the 3D pattern  220 , the lighting image may be implemented as a dual image. Accordingly, a 3D effect may be further spotlighted. 
     However, the lighting image not always implements the dual image, but may implement a single image or a dual image according to a thickness of the lens body  210 , a shape and a location of the 3D pattern 220, and the like. 
     As described above, the front surface  250  may be divided into a light outputting area and a reflection area. 
     The light outputting area may correspond to the area, in which the 3D pattern is formed, and may be configured to output the light. Furthermore, the reflection area may include the reflection area that is configured to totally reflect the light to an area other than the light outputting area. 
     Referring to  FIGS.  3  and  4   , the 3D pattern  220  may include a plurality of unit patterns  221 , and at least one of depths “h” and widths “w” of the plurality of unit patterns  221  may be different. 
     For example, referring to  FIG.  3   , the widths “w” and the depth “h” increase as it goes from the vanishing point. Furthermore, for example, intervals “d” between the unit patterns  221  also may be different. Accordingly, a perspective and a depth feeling of the lighting image may be maximized. 
     The 3D pattern  220  may be formed on the front surface  250  and include an engraved or embossed pattern. 
     Methods for forming the 3D pattern  220  may include a method for forming the 3D pattern  220  during injection-molding of the lens part  200 , and a method for forming the 3D pattern  220  through laser machining after the injection-molding of the lens part  200 . In detail, in the method for engraving the 3D pattern  220  during the injection-molding, the 3D pattern  220  may be formed by forming a pattern corresponding to the 3D pattern  220  in an injection mold for forming the lens body  210 , engraving or embossing the pattern on the front surface  250  during the injection-molding, and performing a corrosion treatment. 
     Furthermore, the laser machining method is a method for forming the 3D pattern  220  on the front surface  250  through a laser after the lens body  210  is injection-molded. Then, a depth of the 3D pattern  220  may be adjusted by adjusting a focus of the laser. Here, the part that is formed during the laser machining may be corroded, and thus, the 3D pattern  220  may be formed. 
     Referring to  FIG.  7   , the 3D pattern  220  also may include an engraved or embossed pattern on the rear surface  240 . Furthermore, the 3D pattern  220  formed on the rear surface  240  may be formed to overlap or miss the 3D pattern  220  formed on the front surface  250  when viewed from the front side. Furthermore, the present disclosure is not limited thereto, and the 3D pattern  220  may be formed only on the rear surface  240 . 
     When the 3D pattern  220  is patterned on both of the front surface  250  and the rear surface  240 , the lighting locations on the front surface  250  and the rear surface  240  may be different due to a thickness of the lens body  210 , and thus, a 3D feeling of the lighting image may be enhanced. 
     Meanwhile, referring to  FIGS.  5  and  6   , the plurality of unit patterns  221  may be formed to be stepped as it goes from a central area to a peripheral area of the lens body  210 . 
     For example, they may be recessed concavely toward the rear side as it goes toward the central area (see  FIG.  5   ), or may be formed to have a shape that protrudes convexly toward the front side. In this case, the lighting image may be implemented 3Dly through the differences of the depths of the plurality of unit patterns  221 , and the gradual pattern. 
     Meanwhile, referring to  FIGS.  9  and  10   , the 3D pattern  220  may be formed by an empty space defined in the interior of the lens body  210 , and may include the plurality of unit patterns  221 . In other words, a shape of the 3D pattern  220  may be defined by the empty spaced in the interior of the lens body  210 . The depths may be adjusted by forming the 3D pattern  220  in the interior of the lens body  210 , whereby the 3D feeling may be enhanced. 
     Through the laser machining, the 3D pattern  220  may be formed in the interior of the lens body  210 . In detail, when a focus is formed in the interior of the lens body  210  by adjusting the location of the focus of the laser during the laser machining, the empty space may be formed in the interior of the lens body  210 , and then a corrosion effect may be shown due to the laser machining. Accordingly, the 3D pattern  220  may be formed in the interior of the lens body  210 . 
     Furthermore, referring to  FIG.  10   , the plurality of unit patterns  221  may be formed at different locations with respect to a thickness direction or rearward direction from the front surface  250  of the lens body  210  to the rear surface  240  of the lens body  210 . 
     For example, as in the illustrated embodiment, the plurality of unit patterns  221  may be configured to be formed at a location that is closer to the front surface  250  as it goes from the central area to the peripheral area of the lens body  210 . Furthermore, the plurality of unit patterns  221  may be configured to be formed at a location that is closer to the rear surface  240  as it goes from the central area to the peripheral area of the lens body  210 . Accordingly, a depth feeling may be given to the lighting image. 
     Meanwhile, referring to  FIGS.  10  to  13   , a plurality of lens bodies  210  may be provided, and the plurality of lens bodies  210  may be arranged in a direction that faces the front side. Furthermore, the light source part  100  may be configured to individually irradiate light toward the plurality of lens bodies  210 . 
     Accordingly, the depth feeling of the lighting image may be enhanced more effectively due to the 3D pattern  220 . Furthermore, various images may be implemented or an image conversion effect may be implemented by one lamp  10  for a vehicle, by individually performing the lighting for the plurality of lens bodies  210 . 
     For example, referring to  FIG.  11   , the plurality of lens bodies  210   a,    210   b,  and  210   c  may be disposed to overlap each other when viewed from the front side. In this case, adjacent ones of the lens bodies  210   a,    210   b,  and  210   c  may be spaced apart from each other or contact each other. This is because the depths of the 3D patterns  220  formed in the lens bodies  210   a,    210   b,  and  210   c  become different due to the thicknesses of the lens bodies  210   a,    210   b,  and  210   c.    
     Furthermore, for example, referring to  FIGS.  12  and  13   , the plurality of lens bodies  210   d,    210   e,    210   f,  and  210   g  may be disposed to be spaced apart from each other. Furthermore, some areas of adjacent ones of the lens bodies  210   d,    210   e,    210   f,  and  210   g  may be disposed to overlap each other when viewed from the front side (see area A 1 , area A 2 , and area A 2  of  FIG.  13   ). 
     That is, instead of a scheme, in which the plurality of lens bodies  210   d,    210   e,    210   f,  and  210   g,  in which the 3D patterns  220  are formed, overlap each other, they may be disposed in the space to miss each other and such that only some areas may overlap each other. Then, a 3D effect of the lighting image may be further enhanced by the 3D feeling implemented by the 3D pattern  220  and the 3D feeling implemented by the spatial feeling between the lens bodies  210   d,    210   e,    210   f,  and  210   g.    
     Meanwhile, the input surface  230  may be formed on a side surface of the lens body  210 , which is a surface in a direction that is perpendicular to a direction that faces the front side, and the light source part  100  may include the plurality of light sources  110 , and may be disposed in a lateral direction of the lens body  210  to irradiate the light toward the input surface  230 . 
     Referring to  FIG.  10   , the light source part  100  may further include a light guide  130  that guides the light irradiated by the plurality of light sources  110  to the lens part  200 . The light guide  130  may guide the light input into an interior of the light guide  130  to the lens part  200  by using internal total reflection. Through the light guide  130 , the light may be uniformly input to the lens part  200 . 
     Referring to  FIG.  11   , the light source part  100  may further include condensing lenses  150  that are disposed the light irradiated by the plurality of light sources  110  and the lens part  200 . Through the condensing lenses  150 , the light diffused from the light sources  110  may be intensively irradiated to the lens part  200 . 
     The lamp for a vehicle according to the embodiment of the present disclosure may implement the imaging image as the 3D image by the 3D pattern formed in the lens part itself while not using a separate special light source, lens, or film. 
     Accordingly, according to the embodiment of the present disclosure, a production value of the product may be enhanced and manufacturing costs and the number of components may be reduced by implementing various different 3D images. 
     Although the specific embodiments of the present disclosure have been described until now, the spirit and scope of the present disclosure are not limited to the specific embodiments, and may be variously corrected and modified by an ordinary person in the art, to which the present disclosure pertains, without changing the essence of the present disclosure claimed in the claims.
