Description

Technical Field

[0001] This invention relates to a vehicle lamp, and more specifically, to a vehicle lamp that forms a pattern of the road surface behind the vehicle when it is reversing. Background Technology

[0002] Typically, vehicles are equipped with lights that have both illumination and signaling functions. The illumination function is used to make it easier to identify objects around the vehicle when driving at night, and the signaling function is used to inform other drivers or pedestrians of the vehicle's driving status.

[0003] For example, vehicle lights that operate by directly emitting light, such as headlights that shine forward to ensure the driver's visibility, brake lights that illuminate when the brake is applied, turn signals that are used when turning right or left, and reversing lights that illuminate when reversing, are installed at the front and rear of the vehicle to reflect light, making the vehicle easily identifiable from the outside.

[0004] Among them, the reversing lights are turned on when the vehicle is reversing, thereby ensuring the driver's nighttime visibility or informing other vehicles that the vehicle is reversing so that other vehicles can prepare accordingly.

[0006] Korean Patent Publication No. 10-1470194 (December 5, 2014) Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a vehicle lamp that forms a pattern of the road surface behind the vehicle when it is reversing.

[0008] The technical problems to be solved by the present invention are not limited to those mentioned above. Those skilled in the art can clearly understand other technical problems not mentioned from the following description.

[0009] A vehicle lamp according to an embodiment of the present invention includes: a light source portion that generates light; a shield portion that selectively transmits a portion of the light from the light source portion; and a lens portion that concentrates the light transmitted through the shield portion onto the road surface, wherein an outwardly protruding portion is formed on the surface of the shield portion.

[0010] The protrusions are provided on the surface of the shielding portion in multiple ways, and the multiple protrusions have the same protruding length relative to the surface of the shielding portion.

[0011] The protrusions are formed in a relatively long manner by continuously connecting different regions of the surface of the shield, and each portion of the protrusion has the same protruding length relative to the surface of the shield.

[0012] The shielding part is made of glass.

[0013] The main transmitted light in the light transmitted through the shield forms multiple road surface patterns, and the auxiliary transmitted light in the light transmitted through the shield illuminates a selected road surface pattern among the multiple road surface patterns, thereby increasing the brightness of the selected road surface pattern.

[0014] The shielding portion includes: a main transmission aperture for forming the main transmitted light; and an auxiliary transmission aperture for forming the auxiliary transmitted light.

[0015] The main transmission apertures are provided in a plurality of manner, and the plurality of main transmission apertures are arranged at different heights relative to each other relative to the road surface. The shape and size of each of the plurality of main transmission apertures are determined in such a manner that the plurality of road surface patterns have the same shape and size.

[0016] The plurality of main transmission apertures are arranged in a row, and at least a portion of the plurality of main transmission apertures are arranged to be detached from the row.

[0017] The main transmission aperture with the largest size among the plurality of main transmission apertures is arranged to be detached from the column.

[0018] The light source unit includes: a main light source unit corresponding to the main transmission aperture; and an auxiliary light source unit corresponding to the auxiliary transmission aperture.

[0019] Each of the main light source section and the auxiliary light source section includes: a light source, illuminating light; and an optical section that causes the light from the light source to irradiate in a unidirectional and linear manner, wherein the optical section has dimensions corresponding to the dimensions of the corresponding main transmission aperture or auxiliary transmission aperture.

[0020] The auxiliary transmitted light illuminates the road surface pattern with relatively low brightness among the plurality of road surface patterns.

[0021] The main transmitted light in the light transmitted through the shield forms multiple road surface patterns with light concentrated in different areas. The auxiliary transmitted light in the light transmitted through the shield illuminates a selected area in the multiple road surface patterns in such a way that the light is concentrated in the selected area, thereby increasing the brightness of the selected area.

[0022] The shielding portion includes: a main transmission aperture for forming the main transmitted light; and an auxiliary transmission aperture for forming the auxiliary transmitted light, wherein the main transmission aperture and the auxiliary transmission aperture have the same shape and size and are arranged in a row.

[0023] The light source unit includes: a main light source unit corresponding to the main transmission aperture; and an auxiliary light source unit corresponding to the auxiliary transmission aperture, wherein the main light source unit and the auxiliary light source unit determine their height and size by means of the corresponding transmission apertures in the main transmission aperture and the auxiliary transmission aperture, thereby concentrating light into a specific area with a specific size.

[0024] The lens section is formed by overlapping convex and concave lenses that have different refractive indices.

[0025] The light transmitted through the shielding portion is transmitted through the concave lens and then through the convex lens.

[0026] The concave lens has a higher refractive index than the convex lens.

[0027] The convex lens is made of polymethyl methacrylate (PMMA), and the concave lens is made of polycarbonate (PC).

[0028] The light source, the shield, and the lens are arranged in an angle that is inclined relative to the road surface.

[0029] Specific details of other embodiments are included in the detailed description and accompanying drawings.

[0030] As described above, the vehicle lights according to embodiments of the present invention have the advantage that when a vehicle is reversing, as a rear road pattern is formed, drivers or pedestrians in the vicinity can recognize that the vehicle is reversing.

[0031] In addition, it has the following advantages: since the shielding material used in vehicle lamps is made of glass, the roughness of the inner surface of the hole is reduced.

[0032] In addition, it has the following advantages: because protrusions are formed on the surface of the shielding component, direct contact between the surfaces of adjacent shielding components can be prevented when multiple shielding components are stacked. Attached Figure Description

[0066] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The advantages and features of the present invention, as well as the methods for achieving these features, will become apparent from the detailed embodiments described below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, which can be implemented in various different forms. These embodiments are provided only to fully disclose the present invention and to fully inform those skilled in the art to which this invention pertains, that the scope of the invention is fully defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same constituent elements.

[0067] Unless otherwise defined, all terms used in this specification (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, unless explicitly defined otherwise, terms as defined in commonly used dictionaries should not be interpreted ideally or excessively.

[0068] Figure 1 and Figure 2 This is a diagram illustrating a road surface pattern formed by a vehicle lamp according to an embodiment of the present invention.

[0069] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, a vehicle lamp 100 can form a road surface pattern 20 on the road surface 30.

[0070] The vehicle lamp 100 can form a road surface pattern 20 by illuminating the road surface 30. Furthermore, the road surface pattern 20 can be formed by concentrating light on a specific location on the road surface 30. In this invention, when the vehicle 10 is reversing, the road surface pattern 20 can be formed on the road surface 30 behind the vehicle 10. For this purpose, the vehicle lamp 100 can be installed behind the vehicle 10.

[0071] Vehicle 10 may be equipped with multiple vehicle lights 100. For example, the vehicle lights 100 may be respectively installed on the left rear and right rear of vehicle 10. Different road surface patterns 20 can be formed by the various vehicle lights 100.

[0072] Each vehicle's lighting fixture 100 can form multiple road surface patterns 20. These multiple road surface patterns 20 can be arranged in a straight line in the rearward direction of the vehicle 10. Alternatively, according to some embodiments of the invention, the multiple road surface patterns 20 can also be arranged in a direction inclined to the left or right relative to the rearward direction of the vehicle 10.

[0073] In this invention, each of the plurality of road surface patterns 20 may have the same shape and size as each other. For example, as Figure 1As shown, each pavement pattern 20 can have a rectangular shape with the same horizontal and vertical lengths. However, it is exemplary that multiple pavement patterns 20 have the same shape and size. According to some embodiments of the present invention, some or all of the multiple pavement patterns 20 may also be different from each other. Hereinafter, pavement patterns 20 having the same shape and size will be described in detail.

[0074] Furthermore, despite Figure 1 and Figure 2 The example shown is of a road surface pattern 20 formed by the vehicle lamps 100 in the form of three patterns; however, this is merely an example, and the number of road surface patterns 20 formed by the vehicle lamps 100 can be determined in various ways. The following description primarily focuses on the case where three road surface patterns 20 are formed by the vehicle lamps 100.

[0075] Figure 3 It is used for explanation Figure 1 and Figure 2 The diagram shown is of a vehicle lighting fixture. Figure 4 It is shown Figure 3 A diagram showing an exemplary configuration of the light source section.

[0076] Reference Figure 3 According to an embodiment of the present invention, a vehicle lamp 100 is configured to include a light source 110, a shielding part 120, and a lens part 130.

[0077] The light source unit 110 can generate light. (See reference...) Figure 4 As will be explained, the light source unit 110 is configured to include a light source 111 and optical units 112 and 113.

[0078] The light source 111 can emit light. In this invention, the light source 111 can be a light-emitting diode (LED), but the light source 111 of this invention is not limited to a light-emitting diode.

[0079] Optical sections 112 and 113 can be as follows Figure 4 As shown in (a), it is provided in the form of a reflector, or it can be provided as... Figure 4 As shown in (b), it is provided in the form of a collimator. Alternatively, the reflector and the collimator can be combined to form the optical parts 112 and 113.

[0080] Re-examine Figure 3To illustrate, the shielding portion 120 selectively transmits a portion of the light from the light source portion 110. For example, the shielding portion 120 may include a blocking region that blocks light and a transmission region that transmits light. A portion of the light from the light source portion 110 can be transmitted through the transmission region, while the remaining portion can be blocked by the blocking region. The light transmitted through the shielding portion 120 can be passed to the lens portion 130.

[0081] The lens section 130 serves to concentrate the light from the transmission shield section 120 onto the road surface 30. The light concentrated on the road surface 30 can form the road surface pattern 20.

[0082] The shielding portion 120 may include multiple transmission regions. A portion of the multiple transmission regions may form primary transmitted light, and another portion may form secondary transmitted light. The primary transmitted light in the light from the transmission shielding portion 120 may form multiple road surface patterns 20. The secondary transmitted light in the light from the transmission shielding portion 120 may illuminate a road surface pattern 20 selected from the multiple road surface patterns 20, thereby increasing the brightness of the selected road surface pattern 20.

[0083] A portion of the multiple road surface patterns 20 formed by the main transmitted light may have a lower brightness than another portion. By illuminating the road surface patterns 20 with relatively low brightness by auxiliary transmitted light, multiple road surface patterns 20 with uniform brightness as a whole can be formed on the road surface 30.

[0084] Figure 5 It is shown Figure 3 The diagram shows an exemplary configuration of a vehicle lighting fixture. Figure 6 It is shown Figure 5 The image shown is an exploded perspective view of the vehicle's lighting fixtures. Figure 7 yes Figure 5 The cross-sectional view of A-A' in the middle. Figure 8 It is a diagram used to illustrate the arrangement of vehicle lights relative to the road surface.

[0085] Reference Figures 5 to 7 The vehicle lighting fixture 200 comprises a light source 300, a shielding part 400, and a lens part 500.

[0086] The light source 300, the shielding part 400, and the lens part 500 can be arranged side by side. That is, the shielding part 400 can be arranged in front of the light source 300, and the light source 300 can be arranged in front of the shielding part 400.

[0087] Reference Figure 8To explain, the arrangement of the light source 300, the shielding part 400, and the lens part 500 can be tilted relative to the road surface 30. As a result, the light generated by the light source 300 can pass through the shielding part 400 and the lens part 500 and be reflected onto the road surface 30, thereby forming the road surface pattern 20.

[0088] Re-examine Figures 5 to 7 As explained, the light source unit 300 can generate light. The light source unit 300 is configured to include a light source 310 and an optical housing 320.

[0089] The light source 310 can emit light. In this invention, the light source 310 can be a light-emitting diode (LED), but the light source 310 of this invention is not limited to a light-emitting diode.

[0090] The optical housing 320 can be connected to the second lens section 520 described later (see reference). Figure 6 The optical housing 320 and the second lens portion 520 can be joined together by means such as bolts. The shielding portion 400 can be arranged in the space formed by the optical housing 320 and the second lens portion 520. With the optical housing 320 and the second lens portion 520 joined together, the distance between the shielding portion 400 and the optical housing 320 and the distance between the shielding portion 400 and the lens portion 500 can be maintained.

[0091] The optical housing 320 may include an optical section 321. The optical section 321 can direct the light from the light source 310 in a linear manner along one side. The linear light can be transmitted to the shielding section 400.

[0092] The light source unit 300 may include a main light source unit 301 and an auxiliary light source unit 302. The main light source unit 301 can generate light for forming a plurality of road surface patterns 20. The auxiliary light source unit 302 can generate light for increasing the brightness of a road surface pattern 20 selected from the plurality of road surface patterns 20. A detailed description of the light source unit 300 will be provided later. Figure 9 This will be discussed later.

[0093] The shielding portion 400 selectively transmits a portion of the light from the light source portion 300. The shielding portion 400 may include a plurality of transmission holes 411, 412, 420 (see reference 1) for transmitting light. Figure 11 Furthermore, the road surface pattern 20 can be formed by transmitting light through multiple transmission holes 411, 412, and 420 onto the road surface 30. A detailed description of the shape and function of the shielding part 400 will be provided later. Figures 11 to 15 This will be discussed later.

[0094] The lens section 500 serves to concentrate the light from the transmission shield section 400 onto the road surface 30.

[0095] The lens section 500 is configured to include a first lens section 510 and a second lens section 520. The first lens section 510 may be configured to include a convex lens 511, and the second lens section 520 may be configured to include a concave lens 521. The first lens section 510 and the second lens section 520 can be combined. For example, the first lens section 510 and the second lens section 520 can be snap-fitted together. For this purpose, one of the first lens section 510 and the second lens section 520 may be equipped with a snap-fit ​​groove, and the other may be equipped with a snap-fit ​​hook. With the first lens section 510 and the second lens section 520 combined, the convex lens 511 and the concave lens 521 can be arranged in an overlapping state.

[0096] Multiple convex lenses 511 and concave lenses 521 can be provided. Overlapping convex lenses 511 and concave lenses 521 can form a main lens section 501 or an auxiliary lens section 502. The main lens section 501 can transmit light from the main light source section 301, thereby concentrating the light used to form multiple road surface patterns 20 onto the road surface 30. The auxiliary lens section 502 can transmit light from the auxiliary light source section 302, thereby concentrating the light used to enhance the brightness of the road surface pattern 20 selected from the multiple road surface patterns 20 onto the road surface 30.

[0097] The convex lens 511 and the concave lens 521 may have different refractive indices. As described below, by overlapping the convex lens 511 and the concave lens 521, which have different refractive indices, the chromatic aberration of the light transmitted through the lens section 500 can be reduced.

[0098] Figure 9 This is the front view of the light source section.

[0099] Reference Figure 9 The light source unit 300 may include a main light source unit 301 and an auxiliary light source unit 302.

[0100] The main light source 301 can generate light for forming the road surface pattern 20, and the auxiliary light source 302 can generate light to increase the brightness of the selected road surface pattern 20 in the road surface pattern 20 formed by the main light source 301.

[0101] The main light source 301 can correspond to the main transmission holes 411 and 412 provided in the shielding part 400 (see reference). Figure 11 The auxiliary light source 302 is equipped with an auxiliary transmission hole 420 provided in the shielding part 400 (see reference). Figure 11 The main light source 301 can be arranged adjacent to the main transmission holes 411 and 412 so that light can be irradiated onto the main transmission holes 411 and 412, and the auxiliary light source 302 can be arranged adjacent to the auxiliary transmission hole 420 so that light can be irradiated onto the auxiliary transmission hole 420.

[0102] Each of the main light source unit 301 and the auxiliary light source unit 302 may include a light source 310 and an optical unit 321. The optical unit 321 may have a size corresponding to the size of the corresponding main transmission aperture 411, 412 or auxiliary transmission aperture 420. In this invention, the main transmission apertures 411, 412 may be formed to be larger than the auxiliary transmission aperture 420. Therefore, the optical unit 321 arranged adjacent to the main transmission apertures 411, 412 may be formed to be larger than the optical unit 321 arranged adjacent to the auxiliary transmission aperture 420. Furthermore, as described below, multiple main transmission apertures 411, 412 may be provided, wherein the largest main transmission aperture 411 may be arranged alone. The area of ​​the largest main transmission aperture 411 may be formed to be larger than the sum of the areas of the remaining main transmission apertures 412. Therefore, the optical unit 321 corresponding to the largest main transmission aperture 411 may be formed to be larger than the optical unit 321 corresponding to the remaining main transmission apertures 412.

[0103] Figure 10 This is the front view of the lens section.

[0104] Reference Figure 10 The lens section 500 is configured to include a main lens section 501 and an auxiliary lens section 502.

[0105] The main lens 501 and the auxiliary lens 502 can be arranged side by side at the same height relative to the road surface 30. When the performance of the main lens 501 and the auxiliary lens 502 is the same, the amount of light concentrated on the road surface 30 by the main lens 501 and the auxiliary lens 502 can be the same for each other.

[0106] Figure 11 This is the front view of the shielding section. Figure 12 It is a diagram used to illustrate the correspondence between the transmission holes of the shield and the road surface pattern.

[0107] Reference Figure 11 and Figure 12 The shielding part 400 may include a plurality of transmission holes 411, 412, and 420.

[0108] Transmission apertures 411, 412, and 420 may include main transmission apertures 411 and 412 and auxiliary transmission aperture 420. Main transmission apertures 411 and 412 can form main transmitted light, and auxiliary transmission aperture 420 can form auxiliary transmitted light.

[0109] Main transmission holes 411 and 412 may be provided. Multiple main transmission holes 411 and 412 may be arranged at different heights relative to the road surface 30.

[0110] The shape and size of each of the plurality of main transmission apertures 411, 412 can be determined in such a way that the plurality of road surface patterns 20 have the same shape and size. As described below, the main transmission aperture that tends to be lower among the plurality of main transmission apertures 411, 412 can form the road surface pattern 20 at a greater distance from the vehicle lamp 200, while the main transmission aperture that tends to be upper among the plurality of main transmission apertures 411, 412 can form the road surface pattern 20 at a closer distance from the vehicle lamp 200.

[0111] Since the light transmitted through the main transmission apertures 411 and 412 is diffused while illuminating, when the multiple main transmission apertures 411 and 412 have the same size, the road surface pattern 20 formed by each main transmission aperture 411 and 412 can be larger as it is farther away from the vehicle lamp 200 and smaller as it is closer to the vehicle lamp 200. The size of the main transmission apertures 411 and 412 used to form multiple road surface patterns 20 with the same shape and size can increase as it moves upward and decrease as it moves downward. When the shape of the road surface pattern 20 is rectangular, the shape of the main transmission apertures 411 and 412 can be trapezoidal, and the size of each main transmission aperture 411 and 412 can be determined in a way that makes the size of the road surface pattern 20 formed on the road surface 30 the same.

[0112] Furthermore, the road surface pattern 20 formed through the relatively small transmission apertures 411 and 412 can have relatively low brightness. That is, among the multiple main transmission apertures 411 and 412, the one located at the bottom can form a road surface pattern 20 with lower brightness.

[0113] Multiple main transmission apertures 411, 412 can be arranged in a row. Furthermore, at least a portion of the multiple main transmission apertures 411, 412 can be arranged to be detached from a row. Specifically, the main transmission aperture 411 with the largest size among the multiple main transmission apertures 411, 412 can be arranged to be detached from the row formed by the remaining main transmission apertures 412. Hereinafter, the main transmission aperture 411 with the largest size is referred to as the first main transmission aperture 411, and the group of remaining main transmission apertures 412 is referred to as the second main transmission aperture 412.

[0114] The area of ​​the first main transmission aperture 411 can be made larger than the area of ​​the second main transmission aperture 412. The main light source unit 301 can be provided independently relative to the first main transmission aperture 411 and the second main transmission aperture 412. When the light from one main light source unit 301 transmits through the entire main transmission aperture, the brightness of the road surface pattern 20 can vary depending on the distance between the vehicle lamp 200 and the road surface pattern 20. By arranging the main light source unit 301 independently relative to the first main transmission aperture 411 and the second main transmission aperture 412, the brightness of the road surface pattern 20 can be uniformly formed, regardless of the distance between the vehicle lamp 200 and the road surface pattern 20.

[0115] The auxiliary transmitted light from the transmission-assisted transmission aperture 420 can illuminate the road surface pattern 20 with relatively low brightness among the multiple road surface patterns 20. As a result, it can be observed that the multiple road surface patterns 20 have uniform brightness.

[0116] The auxiliary transmitted light can form a light pattern on the road surface 30 with the same or similar shape as the road surface pattern 20. For this purpose, the auxiliary transmission aperture 420 can have the same or similar shape and size as the main transmission apertures 411 and 412. Specifically, the shape and size of the auxiliary transmission aperture 420 can be the same or similar to the shape and size of the main transmission aperture 412 among the multiple main transmission apertures 411 and 412 that forms the relatively low-brightness road surface pattern 20. Thus, the light pattern formed on the road surface 30 by transmitting light through the auxiliary transmission aperture 420 can overlap with the low-brightness road surface pattern 20, so that the brightness of the overall road surface pattern 20 can be uniformly formed.

[0117] Figure 13 This is a three-dimensional view of the rear of the shielding section. Figure 14 This is a diagram showing multiple shielding components stacked together. Figure 15 This is a diagram showing the transmission hole of the shielding part. Figure 16 It has the same Figure 13 The diagram shows a three-dimensional view of the rear side of the shielding part of the different protrusions shown.

[0118] Reference Figure 13 A protrusion 430 protruding outward may be formed on the surface of the shielding part 400.

[0119] Multiple protrusions 430 may be provided on the surface of the shielding portion 400, and the multiple protrusions 430 may have the same protruding length relative to the surface of the shielding portion 400. Since the multiple protrusions 430 are provided with the same height, therefore... Figure 14 As shown, multiple shielding portions 400 can be stacked on the mounting surface. During the manufacturing of the shielding portions 400, multiple shielding portions 400 can be stored in one place. At this time, the user can stack multiple shielding portions 400 for storage. Since the protrusions 430 formed on the shielding portions 400 maintain the spacing between adjacent shielding portions 400, damage to the surface of the shielding portions 400 due to friction between them can be prevented.

[0120] Furthermore, in this invention, the shielding portion 400 can be made of glass. Glass is a material that can be easily machined. Therefore, as... Figure 15 As shown, machining of the inner surfaces FC of the transmission holes 411, 412, 420 formed in the shielding portion 400 can be easily performed, and the roughness of the inner surfaces can be reduced.

[0121] The surface of the shielding part 400, made of glass, can be coated with a material that prevents light transmission. Therefore, light can only pass through the transmission holes 411, 412, and 420, and is blocked in the remaining areas.

[0122] The above description shows that multiple protrusions 430 are provided at different positions on the shielding portion 400, but according to another embodiment of the present invention, only one protrusion may be provided on the shielding portion.

[0123] Reference Figure 16 The shielding part 401 may include and Figure 13 The protrusions 430 shown are different from the protrusions 440.

[0124] The protrusion 440 can be formed in an elongated shape to continuously connect different areas on the surface of the shield 401. For example, the protrusion 440 can be formed in a ring shape along the edge of one side surface of the shield 401. In this case, each part of the protrusion 440 can have the same protruding length relative to the surface of the shield 401. As the various parts of the protrusion 440 are equipped with the same height, thus connecting with... Figure 14 Similar to the situation shown, multiple shielding parts 401 can be stacked on the mounting surface.

[0125] The following description will focus on the shielding part 400, which is equipped with multiple protrusions 430.

[0126] Figure 17 This diagram illustrates how chromatic aberration is created by a convex lens. Figure 18 This diagram illustrates how chromatic aberration is removed using a lens. Figure 19 It is a diagram showing the road surface pattern formed by vehicle lights. Figure 20 This is a diagram used to illustrate the function of the lens section based on the position of the transmission aperture.

[0127] Reference Figure 17 If the lens section 500 only includes a convex lens 511, chromatic aberration may occur.

[0128] When the light from the light source 300 is transmitted only through the convex lens 511, the light is separated according to wavelength, and the light rays of different wavelengths may have different focal lengths. In this case, the edges of the road surface pattern 20 may be indistinct, and may form unique colors.

[0129] Reference Figure 18 According to an embodiment of the present invention, the lens portion 500 of the vehicle lamp 200 may include a convex lens 511 and a concave lens 521.

[0130] The convex lens 511 and the concave lens 521 may have different refractive indices. The concave lens 521 may have a higher refractive index than the convex lens 511. For example, the convex lens 511 may be made of polymethyl methacrylate (PMMA), and the concave lens 521 may be made of polycarbonate (PC). However, the materials of the convex lens 511 and the concave lens 521 of the present invention are not limited thereto.

[0131] By overlapping the convex lens 511 and the concave lens 521, the chromatic aberration of the light from the transmission lens section 500 can be reduced.

[0132] With the light-transmitting convex lens 511 and concave lens 521 in the light source section 300, the focal length of light according to the wavelength can be uniformly formed. In this case, the edges of the road surface pattern 20 can be clearly formed.

[0133] Light from the transmission shield 400 can be transmitted through the convex lens 511 after the concave lens 521. The convex lens 511 can concentrate the incident light at a focal point. Thus, by concentrating the light from the convex lens 511 onto the road surface 30, the shape of the road surface pattern 20 can be observed more clearly.

[0134] Reference Figure 19 and Figure 20 The lens section 500 can concentrate the light from the transmission shield section 400 onto the road surface 30.

[0135] The lens section 500 can refract and concentrate the light from the transmission shield section 400 onto the road surface 30. The light concentrated on the road surface 30 can form a road surface pattern 20. The main lens section 501 and the auxiliary lens section 502 can refract light so that the light shines on the corresponding road surface pattern 20.

[0136] Reference Figure 20 The lens 500 can refract light in a manner that concentrates light at different positions on the road surface 30 according to the positions of the transmission holes 411, 412, 420 provided on the shield 400.

[0137] The lens 500 can refract light in a manner that concentrates light closer to the vehicle lamp 200 by positioning the transmission apertures 411, 412, and 420 higher, and concentrate light further away from the vehicle lamp 200 by positioning the transmission apertures 411, 412, and 420 lower. Light transmitted through different transmission apertures 411, 412, and 420 can be refracted by the lens 500 and concentrated on the road surface 30, thereby forming different road surface patterns 20.

[0138] Figure 21 It is shown Figure 3The diagram shows another exemplary configuration of a vehicle lighting fixture. Figure 22 yes Figure 21 The front view of the light source section of the vehicle lamp shown. Figure 23 yes Figure 21 The front view of the shielding part of the vehicle lamp shown.

[0139] Reference Figures 21 to 23 The vehicle lamp 600 is configured to include a light source 700, a shielding part 800, and a lens part 900.

[0140] The light source 700, the shielding part 800, and the lens part 900 can be arranged side by side. That is, the shielding part 800 can be arranged in front of the light source 700, and the light source 700 can be arranged in front of the shielding part 800.

[0141] The light source unit 700 may include a light source 710 and an optical unit 720. The light source 710 can illuminate light, and the optical unit 720 can illuminate the light from the light source 710 in a linear manner along one side.

[0142] The light source unit 700 may include a main light source unit 701 and an auxiliary light source unit 702. The main light source unit 701 and the auxiliary light source unit 702 can form a road surface pattern. In particular, the main light source unit 701 can form a road surface pattern in a specific area of ​​the illumination region where light is concentrated on the road surface, and the auxiliary light source unit 702 can form a road surface pattern for increasing the brightness of a specific area in the road surface pattern of the main light source unit 701.

[0143] The shielding part 800 selectively transmits a portion of the light from the light source part 700. The shielding part 800 may include multiple transmission holes 811, 812, and 820 for transmitting light, and the light transmitted through the multiple transmission holes 811, 812, and 820 can illuminate the road surface to form a road surface pattern.

[0144] The lens section 900 serves to concentrate the light from the transmission shield 800 onto the road surface. The lens section 900 is configured to include a first lens section 910 and a second lens section 920. The first lens section 910 may be configured to include a convex lens, and the second lens section 920 may be configured to include a concave lens.

[0145] The shape and function of the light source 700, shielding part 800 and lens part 900 are similar to those of the light source 300, shielding part 400 and lens part 500 mentioned above. The following description focuses on the differences.

[0146] Reference Figure 22 The light source unit 700 may include a main light source unit 701 and an auxiliary light source unit 702.

[0147] The main light source unit 701 can generate light for forming a road surface pattern with light concentrated in a specific area, and the auxiliary light source unit 702 can generate light for increasing the brightness of the selected area in the road surface pattern formed by the main light source unit 701.

[0148] The main light source unit 701 can be provided corresponding to the main transmission holes 811 and 812 provided in the shielding unit 800, and the auxiliary light source unit 702 can be provided corresponding to the auxiliary transmission hole 820 provided in the shielding unit 800. For this purpose, the main light source unit 701 can be arranged adjacent to the main transmission holes 811 and 812, so that light can be irradiated into the main transmission holes 811 and 812, and the auxiliary light source unit 702 can be arranged adjacent to the auxiliary transmission hole 820, so that light can be irradiated into the auxiliary transmission hole 820.

[0149] Each of the main light source unit 701 and the auxiliary light source unit 702 may include a light source 710 and an optical unit 720. The height and size of the main light source unit 701 and the auxiliary light source unit 702 can be determined by the corresponding transmission holes in the main transmission holes 811, 812 and the auxiliary transmission holes 820, so that light is concentrated to a specific area with a specific size.

[0150] As described below, the main transmission holes 811, 812 and the auxiliary transmission hole 820 formed in the shielding portion 800 can have the same shape and size. Furthermore, light transmitted through each of the main transmission holes 811, 812 and the auxiliary transmission hole 820 can form different road surface patterns. The main light source portion 701 and the auxiliary light source portion 702 form road surface patterns with different shapes by means of transmission holes having the same shape and size. For example, one of the main light source portions 701 can be arranged at a higher position relative to the road surface than the other main light source portion 701, and the auxiliary light source portion 702 can be formed to have a smaller size than the main light source portion 701. In this invention, the size of the light source portion 700 can be understood as the size of the optical portion 720.

[0151] Reference Figure 23 The shielding part 800 may include multiple transmission holes 811, 812, and 820.

[0152] Transmission holes 811, 812, and 820 may include main transmission holes 811 and 812 and auxiliary transmission hole 820. Main transmission holes 811 and 812 can form main transmitted light, and auxiliary transmission hole 820 can form auxiliary transmitted light.

[0153] Multiple main transmission holes 811 and 812 can be provided. The main transmission holes 811 and 812 and the auxiliary transmission holes 820 can have the same shape and size and be arranged in a row. For example, the main transmission holes 811 and 812 and the auxiliary transmission holes 820 can be arranged at the same height relative to the road surface.

[0154] The main transmission apertures 811 and 812 and the auxiliary transmission aperture 820 have the same shape and size, but the locations where light is concentrated and transmitted can be different. For example, one of the main transmission apertures 811 and 812 can concentrate and transmit light at an upper position, while the other can concentrate and transmit light at a central position. In addition, the auxiliary transmission aperture 820 can concentrate and transmit light at a lower position.

[0155] Although the transmission holes 811, 812, and 820 have the same shape and size, the shape of the road surface pattern formed by the light transmitted through each transmission hole 811, 812, and 820 and the area where the light is concentrated can be different depending on the position where the light is concentrated and transmitted.

[0156] Figure 24 This diagram illustrates the road surface pattern formed through the first main transmission aperture. Figure 25 This diagram illustrates the road surface pattern formed through the second main transmission aperture. Figure 26 This diagram illustrates the formation of road surface patterns using auxiliary transmission holes. Figure 27 This diagram illustrates the road surface pattern formed by the main transmission aperture and the auxiliary transmission aperture.

[0157] Reference Figures 24 to 27 The shielding part 800 may include main transmission holes 811 and 812 and auxiliary transmission holes 820.

[0158] The main transmission apertures 811 and 812 may include a first main transmission aperture 811 and a second main transmission aperture 812. The first main transmission aperture 811 can form a road surface pattern 40 where light is concentrated at a close distance relative to the vehicle lamp 600. Light transmitted through the first main transmission aperture 811 can form a road surface pattern 40 that is elongated along the direction of light travel, and a road surface pattern in which light is concentrated at a close distance to the vehicle lamp 600 throughout the entire area of ​​the road surface pattern. In the road surface pattern 40 formed by the first main transmission aperture 811, the area where light is concentrated is called the first concentration region 41.

[0159] The second main transmission aperture 812 can form a road surface pattern 50 where light is concentrated at a distance relative to the vehicle lamp 600. Light transmitted through the second main transmission aperture 812 can form a road surface pattern 50 that is elongated along the direction of light travel, and a road surface pattern 50 in which light is concentrated at a distance from the vehicle lamp 600 throughout the entire area of ​​the road surface pattern 50. In the road surface pattern 50 formed by the second main transmission aperture 812, the area where light is concentrated is referred to as the second concentration region 51.

[0160] The auxiliary transmission aperture 820 can form a road surface pattern 60 where light is concentrated at a distance relative to the vehicle lamp 600. The region 61 where light is concentrated by the auxiliary transmission aperture 820 can be the region farthest from the vehicle lamp 600 within the region where light is concentrated by the second main transmission aperture 812 (i.e., the second concentration region 51). In the road surface pattern 60 formed by the auxiliary transmission aperture 820, the region where light is concentrated is called the auxiliary concentration region 61.

[0161] The length of the second concentrated region 51 formed by the second main transmission aperture 812 can be greater than the length of the first concentrated region 41 formed by the first main transmission aperture 811. In particular, compared with the first concentrated region 41, the second concentrated region 51 can be formed at a greater distance relative to the vehicle lamp 600. Therefore, in the second concentrated region 51, since light does not sufficiently illuminate the portion furthest from the vehicle lamp 600, it can have a lower brightness compared to other portions.

[0162] The auxiliary concentrated area 61 formed by the auxiliary transmission aperture 820 can be formed in the area with relatively low brightness in the second concentrated area 51. Thus, the near-field area of ​​the first concentrated area 41 and the far-field area of ​​the second concentrated area 51 in the entire road surface pattern 40, 50, 60 can be observed with uniform brightness.

[0163] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing its technical concept or essential features. Therefore, the embodiments described above should be understood as exemplary in all respects and not limiting.
