Description

Technical Field

[0001] This invention relates to a vehicle lamp, and more specifically, to a vehicle lamp that forms an optimal beam pattern to ensure the driver's field of vision. Background Technology

[0002] Typically, vehicles are equipped with a variety of lights that provide illumination for easy identification of objects around the vehicle while driving at night, as well as signals to inform surrounding vehicles or pedestrians of the vehicle's status.

[0003] For example, headlights and fog lights are mainly intended for illumination, while turn signals, taillights, and brake lights are mainly intended for signaling. The standards and specifications for the installation of each light fixture have been stipulated by regulations in order to fully realize their respective functions.

[0004] Headlights play a crucial role in ensuring the driver's forward visibility for safe driving. Research is actively underway to ensure a long field of vision and a wide field of vision, as well as to prevent glare caused by light shining in unnecessary directions.

[0005] Existing technical documents Patent documents Patent Publication No. 10-2327018 (Announced on November 16, 2021) Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a vehicle lamp that can ensure the driver's vision and prevent light from shining in unnecessary directions.

[0007] Furthermore, a vehicle lamp is provided that allows adjustment of the beam pattern's light distribution characteristics without changing the light source.

[0008] The technical problems of this invention are not limited to those mentioned above, and those skilled in the art can clearly understand other technical problems not mentioned from the following description.

[0009] To achieve the above-mentioned objectives, the vehicle lamp according to an embodiment of the present invention forms a beam pattern by means of a plurality of lamp modules arranged in a left-right direction, wherein each of the plurality of lamp modules may include: a plurality of light sources; a plurality of reflective surfaces, which respectively reflect light emitted from the plurality of light sources forward to form a patterned area within the beam pattern; and a transmission lens for transmitting light reflected by the plurality of reflective surfaces to form the beam pattern, wherein, among the plurality of reflective surfaces, one reflective surface and another reflective surface may be formed to have different lengths from each other.

[0010] The focal point of the transmission lens can be located on the central reflecting surface among the plurality of reflecting surfaces.

[0011] Among the plurality of reflective surfaces, the reflective surface located closer to the adjacent luminaire module can be formed with a shorter length than the reflective surface located at the focal point of the transmissive lens, using the reflective surface at the focal point of the transmissive lens as a reference.

[0012] Among the plurality of reflecting surfaces, the reflecting surface located further away from the focal point of the transmission lens can be formed to have a shorter length.

[0013] The plurality of lighting modules may include a first lighting module and a second lighting module. The first lighting module may include: a plurality of first light sources; a plurality of first reflective surfaces, each reflecting light emitted from the plurality of first light sources forward; and a first transmission lens, through which light reflected by the plurality of reflective surfaces is transmitted to form the beam pattern. The second lighting module may include: a plurality of second light sources; a plurality of second reflective surfaces, each reflecting light emitted from the plurality of second light sources forward; and a second transmission lens, through which light reflected by the plurality of reflective surfaces is transmitted to form the beam pattern. A portion of the first reflective surfaces belonging to the interference region may be removed from the plurality of first reflective surfaces, and the interference region is defined by the focal length and radius of the second transmission lens.

[0014] The interference region can be circular, and the circular shape can have a radius proportional to the focal length and radius of the second transmission lens, with the center of the second transmission lens as a reference.

[0015] The transmission lens of each of the plurality of lighting modules can be formed such that the incident surface has a rearward convex shape, and the emission surface can be integrally formed in such a way that it forms a continuous surface without step differences.

[0016] Multiple patterned regions formed by light reflected by the multiple reflective surfaces are arranged along the left-right direction. Among the multiple patterned regions, the length of one patterned region in the vertical direction may be different from that of another patterned region in the vertical direction.

[0017] The length of the beam pattern in the vertical direction can decrease from the center toward both sides.

[0018] Other specific aspects of the invention are included in the detailed description and accompanying drawings.

[0019] The vehicle lamp of the present invention as described above has one or more of the following effects.

[0020] Since each of the multiple lighting modules includes multiple light sources and multiple reflective surfaces, and one of the reflective surfaces in each lighting module has a different length from another, it can prevent light interference between adjacent lighting modules, thereby preventing light from shining in an unnecessary direction and producing glare.

[0021] Furthermore, since the light distribution characteristics of the beam pattern can be adjusted by adjusting the length of the multiple reflective surfaces of each of the multiple lamp modules without changing the light source, it has the effect of reducing the structure and cost of adjusting the light distribution characteristics.

[0022] The effects of this invention are not limited to those mentioned above. Those skilled in the art can clearly understand other technical effects not mentioned by referring to the claims. Attached Figure Description

Throughout this specification, the same reference numerals refer to the same constituent elements.

[0034] Hereinafter, the present invention will be described with reference to the accompanying drawings, which are used to describe vehicle lighting fixtures, based on embodiments of the present invention.

[0035] Figure 1 This is a perspective view showing a vehicle lamp according to an embodiment of the present invention. Figure 2 This is a plan view showing a vehicle lamp according to an embodiment of the present invention.

[0036] Reference Figure 1 and Figure 2 The vehicle lamp 1 of the present invention may include a plurality of lamp modules 100, 200, and 300 arranged in the left-right direction.

[0037] In an embodiment of the present invention, the vehicle lamp 1 is described as an example of a headlight used to illuminate the vehicle in the direction of travel to ensure the driver's forward visibility when the vehicle is driving at night. However, it is not limited to this. The vehicle lamp 1 of the present invention can be used not only as a headlight, but also as various lamps installed on the vehicle, such as taillights, brake lights, turn signals, fog lights, reversing lights, and side marker lights.

[0038] At this time, the vehicle lamp 1 of the present invention can be used for one of the aforementioned multiple uses, or it can be used for two or more uses at the same time, and can form a beam pattern that conforms to the light distribution characteristics of the use (i.e., satisfies the position, brightness, size, shape, etc. of the area illuminated by the light).

[0039] When the vehicle lamp 1 of the present invention is used as a headlight, at least one of a low beam pattern and a high beam pattern can be formed. The low beam pattern illuminates downward with reference to the cutoff line to prevent glare to drivers of vehicles in front, such as vehicles traveling in front or oncoming vehicles, thereby ensuring a wide field of vision at close range in front of the vehicle. At least a portion of the high beam pattern is located above the cutoff line to ensure a long field of vision at long distances in front of the vehicle.

[0040] Hereinafter, in embodiments of the present invention, the beam pattern formed by the vehicle lamp 1 is described as follows: Figure 3 As shown, taking the formation of the high beam pattern P as an example, at least a portion of the high beam pattern P is located above the cutoff line CL to ensure a long field of vision in front of the vehicle. In this case, the low beam pattern is also formed at the same time, thereby ensuring a wide field of vision and a long field of vision in front of the vehicle.

[0041] At this time, Figure 3 In this example, the high beam pattern P is formed such that the right side is wider than the left side in the left-right direction, based on the VV line. This is to allow the vehicle lamp 1 of the present invention to be positioned on the right side of the front sides of the vehicle, thereby improving the field of vision on the right side of the vehicle. However, it is not limited to this, and is consistent with the aforementioned... Figure 3Conversely, when the vehicle lamp 1 of the present invention is located on the front left side of the vehicle, the high beam pattern P is formed such that the left side has a greater width than the right side in the left-right direction based on the VV line, thereby improving the field of vision on the left side of the vehicle. When the vehicle lamp 1 of the present invention is located on both sides of the front of the vehicle, the field of vision on the left and right sides can be improved together.

[0042] On the other hand, in the embodiments of the present invention, the case in which multiple lamp modules 100, 200, and 300 are arranged along the vehicle width direction is used as an example to illustrate the case in which multiple lamp modules 100, 200, and 300 are arranged along the left and right direction. However, it is not limited to this. The case in which multiple lamp modules 100, 200, and 300 are arranged along the left and right direction can be understood as assuming that the direction of light irradiation from the vehicle lamp 1 of the present invention is forward, then multiple lamp modules 100, 200, and 300 are arranged along the side.

[0043] For each of the multiple lighting modules 100, 200, and 300, multiple distinct pattern regions can be formed within the high beam pattern P. These multiple pattern regions formed by each of the multiple lighting modules 100, 200, and 300 can be combined to form the aforementioned pattern. Figure 3 The high beam pattern P can reduce the brightness of at least one of multiple pattern areas according to the position of the vehicle in front, so as to prevent glare to the driver of the vehicle in front, and the case of reducing the brightness of at least one of multiple pattern areas may also include the case where no pattern area is formed.

[0044] In an embodiment of the present invention, the following example is used for illustration: multiple lighting modules 100, 200, and 300 are referred to as the first lighting module 100, the second lighting module 200, and the third lighting module 300. The second lighting module 200 is located on one side of the first lighting module 100 in the left-right direction, and the third lighting module 300 is located on the other side of the first lighting module 100 in the left-right direction.

[0045] The first lighting module 100 may include: a plurality of first light sources 111, 112, 113, 114, 115; a plurality of first reflective surfaces 121, 122, 123, 124, 125, which reflect the light emitted from each of the plurality of first light sources 111, 112, 113, 114, 115 so that the light travels forward; and a first transmission lens 130, which transmits the light reflected by the plurality of first reflective surfaces 121, 122, 123, 124, 125 and emits it.

[0046] Each of the plurality of first light sources 111, 112, 113, 114, 115 may include at least one light-emitting element that emits light of a quantity or color suitable for the use of the vehicle lamp 1 of the present invention. In an embodiment of the present invention, an example is given of using a semiconductor light-emitting element such as a light-emitting diode (LED) as at least one light-emitting element.

[0047] Multiple first light sources 111, 112, 113, 114, 115 and multiple first reflective surfaces 121, 122, 123, 124, 125 can be arranged in the same left-right direction as multiple lamp modules 100, 200, 300. The multiple first reflective surfaces 121, 122, 123, 124, 125 reflect light forward in the direction of light irradiated from the first lamp module 100 (i.e., in the direction of light incident on the incident surface 131 of the first transmission lens 130 and emitted through the emission surface 132). The actual forward direction can be different depending on the direction and position of the vehicle lamp 1 according to the present invention.

[0048] Furthermore, the first transmission lens 130 can be formed such that the incident surface 131 has a rearward convex shape, so as to concentrate the light incident on the incident surface 131.

[0049] At this point, one of the multiple first reflective surfaces 121, 122, 123, 124, 125 can be formed to have different lengths from each other in the front-back direction. This is to prevent light interference between adjacent lamp modules of the multiple lamp modules 100, 200, 300, which would cause light to shine in an unnecessary direction. This will be explained in detail later.

[0050] The focal point F1 of the first transmission lens 130 can be located on the first reflecting surface 123 located at the center of the plurality of first reflecting surfaces 121, 122, 123, 124, 125. Based on the first reflecting surface 123 where the focal point F1 of the first transmission lens 130 is located, at least one of the first reflecting surfaces located on both sides can be formed to have a shorter length than the first reflecting surface 123 where the focal point F1 of the first transmission lens 130 is located. This is to prevent light interference between the first lighting module 100 and the lighting modules adjacent to the first lighting module 100.

[0051] At this time, as Figure 4As shown, the vertical distance d1 between the corresponding first light source and the first reflective surface among the plurality of first light sources 111, 112, 113, 114, 115 and the plurality of first reflective surfaces 121, 122, 123, 124, 125 can determine the vertical length of the pattern area formed by the corresponding first light source and the first reflective surface; the horizontal distance d2 between the corresponding first light source and the first reflective surface can determine the horizontal length of the pattern area formed by the corresponding first light source and the first reflective surface; and the horizontal spacing d3 between adjacent first light sources among the plurality of first light sources 111, 112, 113, 114, 115 can determine the position of the pattern area formed by each adjacent first light source.

[0052] At this point, the increase in vertical distance d1 can be understood as the length of the first reflecting surface increasing in the front-to-back direction, and the increase in horizontal distance d2 can be understood as the width of the first reflecting surface increasing in the left-to-right direction.

[0053] Furthermore, the shorter the front-to-back distance d4 between the rear end of the corresponding first reflective surface among the multiple first light sources 111, 112, 113, 114, 115 and the multiple first reflective surfaces 121, 122, 123, 124, 125 and the first light source, the less light loss and the more advantageous it is. However, the distance d4 can be arranged to have an optimal distance that takes into account factors such as color change due to high temperature.

[0054] That is, the shorter the front-to-back distance d4 between the corresponding first light source and the first reflective surface among the multiple first light sources 111, 112, 113, 114, 115 and the multiple first reflective surfaces 121, 122, 123, 124, 125, the less light escapes from the first reflective surface from the light emitted by the first light source, thereby improving the light efficiency. However, as the first light source gets closer to the first reflective surface, the heat generated on the first reflective surface increases, which may cause discoloration, etc. Therefore, the distance d4 is the optimal distance that takes into account both light efficiency and heat.

[0055] In the aforementioned first lighting module 100, light reflected forward from each of the plurality of first reflective surfaces 121, 122, 123, 124, 125 can form different pattern regions within the high beam pattern P. The light distribution characteristics of the pattern regions formed by each of the plurality of first reflective surfaces 121, 122, 123, 124, 125 can be determined by the aforementioned vertical distance d1, horizontal distance d2, horizontal spacing d3, front-back distance d4, etc. Accordingly, even without increasing or changing the number of light-emitting elements included in the first light source corresponding to the plurality of first reflective surfaces 121, 122, 123, 124, 125, the different pattern regions within the high beam pattern P can have different light distribution characteristics, thereby reducing the number of components required to form pattern regions with different light distribution characteristics, and thus reducing costs.

[0056] In other words, when light emitted from each of the plurality of first light sources 111, 112, 113, 114, 115 directly passes through the first transmission lens 130 to form a patterned area, although it is necessary to change the number of light-emitting elements included in the plurality of first light sources 111, 112, 113, 114, 115 when the light distribution characteristics of the patterned area change, in the embodiments of the present invention, even without changing the number of light-emitting elements, the light distribution characteristics of the patterned area can be adjusted by adjusting the aforementioned vertical distance d1, horizontal distance d2, horizontal spacing d3, and front-to-back distance d4, thereby preventing an increase in the number of required components and costs.

[0057] Similar to the first lighting module 100, the second lighting module 200 may include: a plurality of second light sources 211, 212, 213, 214, 215; a plurality of second reflective surfaces 221, 222, 223, 224, 225, which reflect light emitted from the plurality of light sources 211, 212, 213, 214, 215 respectively, so that the light travels forward; and a second transmission lens 230, which transmits light reflected by the plurality of second reflective surfaces 221, 222, 223, 224, 225. The second transmission lens 230 may be formed such that the incident surface 231 has a rearward convex shape, so as to focus the light incident on the incident surface 231. The emission surface 232 and the emission surface 132 of the first transmission lens 130 are integrally formed in a continuous manner without step difference, thereby achieving a unified appearance.

[0058] The focal point F2 of the second transmission lens 230 can be formed on the second reflection surface 223 located at the center of the plurality of second reflection surfaces 221, 222, 223, 224, 225. Taking the second reflection surface 223 where the focal point F2 of the second transmission lens 230 is located as a reference, at least one of the second reflection surfaces located on both sides can be formed to have a shorter length than the second reflection surface 223 where the focal point F2 of the second transmission lens 230 is located. This is to prevent light interference between the second lamp module 200 and the lamp module adjacent to the second lamp module 200, which would cause the light to shine in an unnecessary direction.

[0059] That is, such as Figure 5 As shown, the radius R2 of the interference region A that may be affected by light interference from the lamp module (i.e., the first lamp module 100) adjacent to the second lamp module 200 can be defined based on the radius W of the second transmission lens 230 and the focal length R1 of the second transmission lens 230. The radius R2 of the interference region A can be obtained by R2 = R1 + R1 * (W / 2R1).

[0060] That is, it can be understood that the radius R2 of the interference region A increases as the focal length R1 of the second transmission lens 230 increases, and also increases as the radius W of the second transmission lens 230 increases.

[0061] At this time, if a portion of at least one of the plurality of first reflective surfaces 121, 122, 123, 124, 125 of the first lighting module 100 is located within the interference region A, the light Li reflected by the first reflective surface located within the interference region A may be incident on the incident surface 231 of the second transmission lens 230 and thus illuminate in an unnecessary direction. Therefore, light interference caused by the first lighting module 100 can be prevented by removing a portion (dashed line) of at least one of the plurality of first reflective surfaces 121, 122 located within the interference region A.

[0062] Furthermore, since the interference region A has a circular shape with a radius R2 based on the center of the second transmission lens 230, wherein the radius R2 is obtained by the radius W of the second transmission lens 230 and the focal length R1 of the second transmission lens 230, when a portion of two or more consecutive first reflection surfaces 121, 122, 123, 124, 125 are located within the interference region A, based on the first reflection surface 123 located at the center of the plurality of first reflection surfaces 121, 122, 123, 124, 125, the first reflection surface closer to the second lamp module 200 in the left-right direction has a shorter length.

[0063] Similarly, the first lighting module 100 may also experience light interference due to the second lighting module 200. In this case, a portion of at least one of the plurality of second reflecting surfaces 221, 222, 223, 224, 225 located within the interference region can be removed. The interference region is determined based on the focal length and radius of the first transmission lens 130. Furthermore, taking the second reflecting surface 223 located at the center of the plurality of second reflecting surfaces 221, 222, 223, 224, 225 as a reference, the second reflecting surface closer to the first lighting module 100 has a shorter length.

[0064] In the foregoing embodiments, the light reflected by the first reflecting surface 123 where the focal point F1 of the first transmission lens 130 among the plurality of first reflecting surfaces 121, 122, 123, 124, 125 is located, and the light reflected by the second reflecting surface 223 where the focal point F2 of the second transmission lens 230 among the plurality of second reflecting surfaces 221, 222, 223, 224, 225 is located, has a relatively high luminous intensity. Therefore, in order to ensure a sufficient field of view, it can be formed to have the longest length to improve light efficiency.

[0065] In addition, similar to the first lighting module 100 and the second lighting module 200, the third lighting module 300 may include: a plurality of third light sources 311, 312, 313, 314, 315, 316, 317, and 318; a plurality of third reflective surfaces 321, 322, 323, 324, 325, 326, 327, and 328, reflecting light emitted from the plurality of third light sources 311, 312, 313, 314, 315, 316, 317, and 318 respectively, so that the light travels forward; and a third transmission lens 330, for receiving light emitted from the plurality of third reflective surfaces 321, 322, 323, 324, 325, 326, 327, and 328. 3, 324, 325, 326, 327, 328 reflect light transmission, wherein the third transmission lens 330 can be formed such that the incident surface 331 has a rearward convex shape, so as to concentrate the light incident on the incident surface 331. The exit surface 332 is formed in a continuous manner with no step difference, so that the exit surface 132 of the first transmission lens 130, the exit surface 232 of the second transmission lens 230 and the exit surface 332 of the third transmission lens 330 are formed integrally in a continuous manner with no step difference, thereby achieving a unified appearance.

[0066] The focal point F3 of the third transmission lens 330 can be formed on the central third reflection surface 324 among the plurality of third reflection surfaces 321, 322, 323, 324, 325, 326, 327, and 328. Based on the third reflection surface 324 where the focal point F3 of the third transmission lens 330 is located, at least one of the third reflection surfaces on either side can be formed to have a shorter length than the third reflection surface 324 where the focal point F3 of the third transmission lens 330 is located, as described above. Figure 5 Similarly, this is to prevent light interference between the third lighting module 300 and the lighting module adjacent to the third lighting module 300 (i.e., the first lighting module 100), which would cause light to shine in an unnecessary direction.

[0067] At this point, in conjunction with the aforementioned Figure 5 Similarly, due to the circular interference region obtained by the focal length and radius of the first transmission lens 130, with the third reflection surface 324 located in the center of the plurality of third reflection surfaces 321, 322, 323, 324, 325, 326, 327, 328 as a reference, the third reflection surface closer to the first lamp module 100 has a shorter length.

[0068] Furthermore, since the first lighting module 100 is simultaneously affected by the interference region based on the second lighting module 200 and the interference region based on the third lighting module 300, the first reflecting surface 123, where the focal point F1 of the first transmission lens 130 among the multiple first reflecting surfaces 121, 122, 123, 124, and 125 is located, can be formed to have a shorter length on both sides, the closer they are to the second lighting module 200 and the third lighting module 300, respectively.

[0069] Furthermore, although no adjacent lamp modules are provided in the second lamp module 200 in the left-right direction opposite to the first lamp module 100, the second reflective surface located in the opposite direction from the first lamp module 100 is formed with reference to the second reflective surface 223 where the focal point F2 of the second transmission lens 230 of the plurality of second reflective surfaces 221, 222, 223, 224, 225 is located. The second reflective surface located in the opposite direction from the first lamp module 100 is also formed such that the further away from the focal point F2 of the second transmission lens 230 is located, the shorter its length. This is because the vertical length of the beam pattern formed by the vehicle lamp 1 of the present invention gradually shortens from the center to both sides.

[0070] Furthermore, for reasons similar to those of the second lighting module 200, the third lighting module 300 is also configured such that, based on the third reflecting surface 324 where the focal point F3 of the third transmission lens 330 among the plurality of third reflecting surfaces 321, 322, 323, 324, 325, 326, 327, and 328 is located, the third reflecting surface located in the opposite direction to the first lighting module 100 has a length that becomes shorter the further away from the third reflecting surface 324 where the focal point F3 of the third transmission lens 330 is located.

[0071] Figure 6 This is a schematic diagram showing a patterned region within a beam pattern formed by multiple lamp modules according to an embodiment of the present invention.

[0072] Reference Figure 6 Since the light reflected by the first reflecting surface 123 where the focal point F1 of the first transmitting lens 130 in the first lighting module 100 is located, the second reflecting surface 223 where the focal point F2 of the second transmitting lens 230 in the second lighting module 200 is located, and the third reflecting surface 324 where the focal point F3 of the third transmitting lens 330 in the third lighting module 300 is located has relatively high luminous intensity, it forms pattern regions ⑧, ⑨, and ⑩ near the center of the far beam pattern P, thereby increasing the field of view distance.

[0073] In the first lighting module 100, taking the first reflecting surface 123 where the focal point F1 of the first transmitting lens 130 is located as a reference, the first reflecting surfaces on both sides are formed such that the farther away from the focal point F1 of the first transmitting lens 130, the shorter the length of the first reflecting surface 123. Therefore, pattern areas ④ and ⑦ are formed with shorter lengths in the vertical direction as they move towards the left and right. , .

[0074] In the second lighting module 200, taking the second reflecting surface 223 where the focal point F2 of the second transmission lens 230 is located as a reference, the second reflecting surfaces on both sides are formed such that the further away from the focal point F2 of the second transmission lens 230, the shorter the length of the second reflecting surface 223. Therefore, pattern areas ② and ⑤ are formed with shorter lengths in the vertical direction as they move towards the left and right. , .

[0075] In the third lighting module 300, similar to the first lighting module 100 and the second lighting module 200, with the third reflecting surface 324 where the focal point F3 of the third transmission lens 330 is located as a reference, the third reflecting surfaces on both sides also form pattern areas ①, ③, and ⑥ that are shorter in length in the vertical direction as they move further to the left and right. , , , .

[0076] At this time, Figure 6 In this context, the patterned area formed by each reflecting surface can be understood as a patterned area assigned the same number as the number assigned to each reflecting surface.

[0077] As described above, for the vehicle lamp 1 of the present invention, since the light distribution characteristics of the patterned area formed by the light emitted from the light source can be changed according to the width and length of the reflective surface, the light distribution characteristics of the patterned area can be changed without changing the light source, thereby preventing an increase in the number of parts and reducing costs.

[0078] Those skilled in the art will understand that the invention can be implemented in other specific forms without altering the technical concept or essential features. Therefore, the embodiments described above are exemplary in all respects and should be understood as not limiting embodiments. The scope of the invention is not limited by the foregoing detailed description, but by the claims. All modifications or variations that can be derived from the meaning, scope, and equivalents of the claims should be interpreted as included within the scope of the invention.
