[0002] This application claims priority to Korean Patent Application No. 10-2025-0008245, filed with the Korean Intellectual Property Office on January 20, 2025, the entire contents of which are incorporated herein by reference. Technical Field
[0003] This disclosure relates to a lamp for a vehicle. Background Technology
[0004] In a microlens array (MLA), images are projected by arranging multiple microlenses. Microlens arrays are widely used in various fields because they can display high-quality images in a small size.
[0005] In particular, in recent years, microlens arrays have been used as components for implementing signal lighting functions (welcome light function, turn indicators, etc.) in vehicles due to their ability to draw specific patterns on the road using an optical system with a size of about 10 mm.
[0006] However, according to conventional technology, because the light diffusion angle in the microlens array is small, about 15 degrees, other lighting functions (such as low beam function) cannot be implemented in the vehicle except for the welcome light function. Therefore, the use of the microlens array in the vehicle is limited. Utility Model Content
[0007] This disclosure is proposed to address the aforementioned problems in the prior art while fully preserving the advantages achieved by the prior art.
[0008] One aspect of this disclosure provides a lamp for a vehicle, by which various functions (such as low beam) can be implemented by expanding the diffusion angle of the light output from the MLA module.
[0009] The technical problems to be solved by this disclosure are not limited to those described above, and any other technical problems not mentioned herein will be clearly understood by those skilled in the art from the following description.
[0010] According to one aspect of this disclosure, a lamp for a vehicle may include a light source that generates and outputs light, and an MLA module disposed in front of the light source, to which light is input; the MLA module may include: an input lens array to which light is input, and including a plurality of input lenses; and an output lens array disposed in front of the input lens array, receiving light input to the input lens array and outputting the light to the outside, and including a plurality of output lenses, the plurality of output lenses each corresponding to at least some of the input lenses; and when the distance between the optical axis of any one of the plurality of input lenses and the optical axis of any one of the plurality of output lenses corresponding to any one of the input lenses is defined as the inter-optical distance in the left / right direction of the MLA module, the inter-optical distance may gradually increase from the center portion to the periphery of the MLA module.
[0011] The multiple input lenses can form different shapes.
[0012] Each of the plurality of input lenses may have a horizontal radius of curvature and a vertical radius of curvature, which are different from each other.
[0013] Relative to the horizontal direction, among the plurality of input lenses, the radius of curvature of the outermost input lens can be smaller than the radius of curvature of the input lens adjacent to it.
[0014] When the input lens array is viewed from the front, the outermost input lens among the plurality of input lenses can be formed as a semicircle.
[0015] The input lens array can be divided into a first region and a second region disposed at the upper end of the first region relative to the vertical direction, and the size of the plurality of input lenses disposed in the second region in the vertical direction can be formed to be larger than the size of the plurality of input lenses disposed in the first region in the vertical direction.
[0016] The number of input lenses disposed in the first region can be greater than the number of input lenses disposed in the second region.
[0017] The plurality of input lenses disposed in the second region can be arranged in multiple rows, and the input lenses in the rows can be formed to have different sizes in the vertical direction.
[0018] The plurality of input lenses disposed in the second region can be arranged in multiple rows, and the input lenses in the rows can be formed to have different radii of curvature in the vertical direction.
[0019] Relative to the vertical direction, the optical axis of any one of the multiple input lenses can be formed at the same height as the optical axis of any output lens corresponding to any input lens.
[0020] The radii of curvature of the multiple output lenses can be the same.
[0021] Each of the plurality of output lenses may have the same horizontal radius of curvature and vertical radius of curvature.
[0022] The number of input lenses can be greater than the number of output lenses.
[0023] The input lens array can be divided into a central region and an outer region located at the end of the central region in a left / right direction relative to the horizontal direction, and the input lenses located in the central region can correspond to the output lenses respectively.
[0024] The MLA module may further include a shield disposed between the input lens array and the output lens array, and the shield is disposed at a position corresponding to the focal point of the plurality of output lenses disposed in the output lens array.
[0025] The MLA module can form a near-beam pattern. Attached Figure Description

[0042] Reference Figures 1 to 11 According to the present disclosure, the lamp 10 for a vehicle includes a light source 100 and a microlens array (MLA) module 200.
[0043] The light source 100 is configured to generate and output light.
[0044] For example, the light source 100 may be configured to irradiate light in a direction facing the MLA module 200. For example, the light source 100 may be a light emitting diode (LED), but this disclosure is not limited thereto.
[0045] Furthermore, for example, this disclosure may also include a collimator 300 disposed between the light source 100 and the MLA module 200. The collimator 300 may be configured such that light input from the light source 100 is converted into parallel light and then emitted to the MLA module 200.
[0046] MLA module 200 is disposed in front of light source 100 and configured to allow light input to MLA module 200. The module may include multiple microlenses on its input surface and output emission surface.
[0047] MLA module 200 includes input lens array 210 and output lens array 220.
[0048] Light is input to the input lens array 210, and the input lens array 210 includes a plurality of input lenses 211. In addition, the output lens array 220 is disposed in front of the input lens array 210, receives the light input to the input lens array 210 and outputs it to the outside, and includes a plurality of output lenses 221.
[0049] Specifically, the MLA module 200 may include an input lens array 210 and an output lens array 220. The input lens array 210 is configured to face the collimator 300 and light is input to the input lens array 210. The output lens array 220 receives the light input to the input lens array 210 and outputs it to the outside.
[0050] The input lens array 210 may include a plurality of input lenses 211 as microlenses. As shown in the figure, the plurality of input lenses 211 may be convex lenses that protrude toward the light source 100.
[0051] Here, each of the multiple input lenses can be configured to have a radius of curvature in the horizontal direction "H" and a radius of curvature in the vertical direction "V", which are different from each other. For example, the radius of curvature of each of the multiple input lenses in the horizontal direction "H" can be smaller than the radius of curvature in the vertical direction "V". In other words, the curvature in the horizontal direction "H" can be greater than the curvature in the vertical direction "V". In this case, light output from the light source 100 and input to the input lens array 210 can diffuse in the horizontal direction "H" while passing through the multiple input lenses. Therefore, according to this disclosure, light diffusion (especially light diffusion in the horizontal direction "H") occurs significantly more than in conventional microlens arrays.
[0052] Meanwhile, the multiple output lenses 221 are configured to correspond to at least a portion of the multiple input lenses 211.
[0053] Furthermore, in the left / right direction of the MLA module 200, when the distance between the optical axis of any one of the multiple input lenses 211 and the optical axis of any one of the multiple output lenses 221 corresponding to any one input lens 211 is defined as the inter-optical axis distance, the inter-optical axis distance gradually increases from the center portion to the outer portion of the MLA module 200.
[0054] For example, refer to Figures 3 to 5 The input lens 211 and output lens 221 can be paired sequentially from the center to the periphery of the MLA module 200 in the left / right direction. However, since the number of input lenses 211 and the number of output lenses 221 are not necessarily the same, the input lenses 211 and output lenses 221 may not be in a one-to-one correspondence. For example, when the number of input lenses 211 is greater than the number of output lenses 221, the outermost input lens 211a in the left / right direction may not have a corresponding output lens. However, the number and corresponding structure of the input lenses 211 and output lenses 221 are not limited to this.
[0055] For ease of description, the distance between the optical axis of the input lens 211 and the optical axis of the output lens 221, which is positioned at the corresponding location on the input lens 211, will be defined as the inter-axis distance. For example, when describing... Figure 5In the example shown, the optical axis distance between the input lens 211 and the output lens 221 located at the center of the MLA module 200 can be S0, and the optical axis distance between the input lens 211 and the output lens 221 located on its periphery can be S6. The optical axis distances formed by the input lens 211 and the output lens 221 arranged sequentially from the center to the periphery can be defined as S1, S2, S3, S4, and S5.
[0056] In this case, the distance between the optical axes can gradually increase in the order of S0, S1, S2, S3, S4, S5, and S6. In other words, the optical axes of the output lens 221 and the corresponding input lens 211 can gradually move away from each other from the center to the periphery relative to the left / right direction.
[0057] Here, the inter-axis distance S0 formed in the central part can be 0. In this case, the position of the optical axis of the output lens 221 in the horizontal direction "H" can be the same as the position of the optical axis of the input lens 211 in the horizontal direction "H".
[0058] When the optical axis of the input lens is positioned differently in the horizontal direction "H" from the optical axis of the output lens 221, the amount of light reaching the periphery of the output lens 221, which corresponds to the input lens 211, can be increased. In this case, the degree of light diffusion can be increased. In other words, the diffusion angle of the light output from the output lens 221 can be increased. Therefore, the optical axes of the input lens 211 and the output lens 221 can be spaced apart to increase the width of the light.
[0059] In this case, as the interaxial distance gradually increases towards the periphery of the MLA module 200, the light diffusion angle can increase for the output lens 221, which is positioned closer to the periphery of the output lens array 220 in the left / right direction. Therefore, the diffusion angle of the light output from the MLA module 200 increases.
[0060] According to this structure, the MLA module 200, which includes multiple microlenses, can be used to realize not only a lamp that performs signal illumination functions, but also a lamp that performs various other functions. For example, the MLA module 200 according to this disclosure can ensure a minimum diffusion angle of the low beam (approximately ±35 degrees or greater), thereby enabling the low beam to be realized by using a microlens array.
[0061] As described above, the MLA module 200 according to this disclosure can realize a lamp that performs various functions by expanding the diffusion angle of the output light as the inter-optical distance gradually increases from the center portion to the periphery in the left / right direction.
[0062] More specifically, even when the output lens 221 unit is replaced with the MLA module 200 according to this disclosure in an existing projection optical system, a low beam lamp can still be achieved.
[0063] Meanwhile, multiple input lenses 211 can be formed into different shapes.
[0064] Specifically, all or part of the multiple input lenses 211 can be formed into different shapes. For example, the radii of curvature of the multiple input lenses 211 can be different. Therefore, the degree of light diffusion of the input lenses 211 can be different.
[0065] For example, refer to Figure 5 Relative to the horizontal direction "H", among the multiple input lenses 211, the radius of curvature of the outermost input lens 211a can be smaller than the radius of curvature of the adjacent input lens 211. In other words, among the multiple input lenses 211, the curvature of the outermost input lens 211a can be the largest.
[0066] Thus, when the curvature of the outermost input lens 211a is large, the light propagating from the outermost input lens 211a to the output lens 221 can be guided to the center of the outermost output lens 221a in the output lens array 220. In other words, the light input to the outermost input lens 211a can be concentrated at the center of the outermost output lens 221a.
[0067] Therefore, the intensity of the light output from the MLA module 200 can be increased. In other words, when using the MLA module 200 according to this disclosure, both the width and intensity of the light can be ensured simultaneously.
[0068] Furthermore, for example, when the input lens array 210 is viewed from the front, the outermost input lens 211a among the multiple input lenses 211 can be formed as a semicircle.
[0069] Specifically, such as in Figure 3 In the illustrated embodiment, the input lens 211, located in the portion excluding the outermost part, may have a central portion that, when viewed from the front, protrudes towards the light source 100. On the other hand, the input lens 211a located on the outermost part may have a semi-circular shape when viewed from the front.
[0070] Therefore, according to this disclosure, most of the light from the light source 100 reaching the input lens 211a disposed on the outermost side of the input lens array 210 can be focused onto the output lens 221a disposed on the outermost side of the output lens array 220. Thus, the intensity of the light output from the MLA module 200 can be further increased.
[0071] Furthermore, for example, the number of input lenses 211 can be greater than the number of output lenses 221.
[0072] As described above, the curvatures of the multiple input lenses 211 can be different. Furthermore, among the multiple input lenses 211, the radius of curvature of the outermost input lens 211a can be large, and when it is necessary to ensure the intensity of light, the radius of curvature can increase as it moves outward in the left / right direction.
[0073] Therefore, according to this disclosure, by forming the MLA module 200 such that the number of input lenses 211 is greater than the number of output lenses 221 relative to the left / right direction, sufficient light intensity can be ensured. For example, in this case, each of the plurality of output lenses 221 may correspond to some of the plurality of input lenses 211.
[0074] More specifically, relative to the horizontal direction "H", the input lens array 210 can be divided into a central region and an outer region located at the ends of the central region in a left / right direction.
[0075] Furthermore, the multiple input lenses 211 disposed in the central region can each correspond to a multiple output lenses 221.
[0076] Therefore, as Figure 5 As shown in the embodiment, the input lens array 210 may further include an input lens 211 in the outer region, compared to the output lens array 220.
[0077] At the same time, refer to Figure 3 , Figure 4 and Figures 6 to 10 The input lens array 210 can be divided into a first region I and a second region II, with the second region II positioned at the upper end of the first region I relative to the vertical direction “V”.
[0078] Furthermore, the size of the plurality of input lenses 211b and 211c disposed in the second region II in the vertical direction “V” can be larger than the size of the plurality of input lenses 211 disposed in the first region I in the vertical direction “V”.
[0079] Specifically, the first region I and the second region II are regions obtained by dividing the input lens array 210 into regions relative to the vertical direction “V”. For example, as in the illustrated embodiment, most of the input lenses 211 can be disposed in the first region I, and the upper portion (e.g., the first and second rows) can be the second region II. However, the second region II is not limited to the input lenses 211 disposed in the first and second rows, but can be varied according to the lamp design specifications. For example, the second region II may include only the input lenses 211 of the first row, or it may include three or more rows of input lenses 211.
[0080] Here, the size of the input lenses 211b and 211c, which are disposed in the second region II in the vertical direction "V", can be larger than the size of the input lens 211 disposed in the first region I in the vertical direction "V". For example, the size of the input lens 211 disposed in the first region I in the vertical direction "V" can be the same.
[0081] In this way, the input lenses 211b and 211c, located in the upper second region II, can be made larger than the input lens 211 located below them, thus extending the entire area of the input lens array 210 upwards. Therefore, the path of light input to the input lenses 211b and 211c in the second region II can be altered, thereby ensuring short-range light in front of the vehicle.
[0082] Specifically, Figure 7 and Figure 8 yes Figure 6 An enlarged view of region A1 is shown, illustrating the path of light input to the first region I of the input lens array 210. Furthermore, Figure 8 yes Figure 7 A magnified view of area A2.
[0083] exist Figures 6 to 8 In this diagram, CH1 represents the baseline for dividing the optical path relative to the multiple output lenses 221. The optical path forms multiple independent channels through CH1. In other words, within the optical channels, corresponding optical paths are formed between the input lens 211 and the output lens 221. When designing the MLA module 200, it can be designed to minimize the interference of light between the independent optical channels.
[0084] Figure 7 and Figure 8 R11 and R12 represent the light rays in the optical paths of adjacent optical channels. The light entering the input lens 211 forms a path in which it propagates toward the center of the corresponding output lens 221.
[0085] at the same time, Figure 9 yes Figure 6 The image shows an enlarged view of region B1, and illustrates the path of light input to the first region I of the input lens array 210. Furthermore, Figure 10 yes Figure 9 A magnified view of area B2.
[0086] exist Figure 6 , 9 In equation 10, CH1 represents the reference line for dividing the optical path relative to the plurality of output lenses 221. Furthermore, CH2 represents the reference line used to explain the optical path altered by the input lens 211 of the second region II. Specifically, the optical channel formed by CH2 is formed by the optical path altered by the input lens 211 of the second region II. Additionally, R21 and R22 represent the rays showing the optical path of the input lens 211 of the second region II.
[0087] Referring to the diagram, because the size of the input lens 211 in the second region II in the vertical direction "V" is larger than the size of the input lens 211 in the first region I in the vertical direction, the light input through the input lens 211 in the second region II can form a downward-sloping optical path compared to the first region I (see Figure 1). Figure 9 and 10 (Light ray R22).
[0088] Therefore, the light input through the input lens 211 in the second region II can form an optical path, wherein when it is output through the lamp 10 for the vehicle, it is output to a short-range region (a region approximately -15 degrees relative to the vertical direction "V"). Thus, short-range light can be ensured. According to this configuration, when the low beam function of the lamp 10 for the vehicle according to this disclosure is implemented, a light intensity distribution that satisfies this rule can be formed.
[0089] At the same time, refer to Figure 6 and Figure 9 Multiple input lenses 211b and 211c set in the second region II can be set in multiple rows, and the input lenses 211b and 211c in the rows can have different sizes in the vertical direction “V”.
[0090] As an example, the second region II may include two rows, and the size of the input lens disposed in the first row (the top row) in the vertical direction "V" may be smaller than the size of the input lens 211b disposed in the second row. However, according to embodiments of this disclosure, the input lenses 211b and 211c disposed in the second region II of the input lens array 210 are not limited to being disposed in two rows; obviously, they may be disposed in one row or three or more rows.
[0091] Furthermore, the input lenses 211b and 211c arranged in the second region II of the input lens array 210 are not limited to the case where the size of the input lens in the first row in the vertical direction “V” is smaller than the size of the input lens in the second row, and can be modified and implemented in various ways according to the design specifications of the lamp.
[0092] Furthermore, for example, the multiple input lenses 211 disposed in the second region II can be arranged in multiple rows, and the input lenses 211 in the rows can have different radii of curvature in the vertical direction “V”.
[0093] Specifically, the input lenses 211 disposed in the first region I are arranged in multiple rows, and the input lenses 211 disposed in the multiple rows in the first region I have the same curvature in the vertical direction "V" to have a uniform shape. At the same time, the input lenses 211b and 211c disposed in the second region II are disposed in multiple rows, but the input lenses 211 disposed in the multiple rows in the first region I can have different radii of curvature in the vertical direction "V" to have a non-uniform shape.
[0094] However, the input lenses 211b and 211c arranged in the second region II of the input lens array 210 according to the embodiments of this disclosure are not limited to the case where the size of the input lens in the first row in the vertical direction “V” is smaller than the size of the input lens in the second row, and various modifications and implementations can be made according to the design specifications of the lamp.
[0095] Furthermore, for example, the number of input lenses 211 disposed in the first region I can be greater than the number of input lenses 211b and 211c disposed in the second region II. Specifically, as described above, most of the input lenses 211 disposed in the input lens array 210 can be disposed in the first region I.
[0096] At the same time, refer to Figure 6 Relative to the vertical direction “V”, the optical axis of any one of the multiple input lenses 211 can be formed at the same height as the optical axis of any output lens in the output lens 221 corresponding to any input lens 211.
[0097] Therefore, the beam pattern formed by the lamp 10 for a vehicle according to this disclosure can be formed to have a narrow width in the vertical "V" direction. As described above, this is based on the principle that when the optical axis of the input lens 211 and the optical axis of the output lens 221 do not coincide with each other, the width of the output light increases, while when the optical axis of the input lens 211 and the optical axis of the output lens 221 coincide with each other, the width of the output light decreases.
[0098] The lamp according to this disclosure can form a low beam pattern, and in this case, the width M1 of the low beam pattern in the vertical direction can be relatively narrower than the width M2 in the horizontal direction "H". Therefore, since the optical axes of the corresponding input lens 211 and the output lens 221 are formed at the same height, the light diffuses less in the vertical direction "V", thus achieving a narrow width of the low beam pattern in the vertical direction "V".
[0099] Furthermore, the plurality of output lenses 221 disposed in the output lens array 220 according to this disclosure may include features different from those of the plurality of input lenses 211. The output lenses 221 may be convex lenses protruding in an output direction D1 opposite to that of the light source 100.
[0100] Furthermore, the radii of curvature of the multiple output lenses 221 can be formed to be the same.
[0101] Furthermore, each of the plurality of output lenses 221 may have the same radius of curvature in the horizontal direction "H" and the same radius of curvature in the vertical direction "V". Specifically, each of the plurality of output lenses 221 may be formed of a rotationally symmetric aspherical lens.
[0102] Therefore, among the output lenses 221 provided in the output lens array 220, the curvature of the outermost output lens 221a and the other output lens 221 can be the same within an error range relative to the horizontal direction "H". Furthermore, for example, among the output lenses 221 provided in the output lens array 220, the size of the uppermost output lens 221 in the vertical direction "V" and the size of the other output lens 221 in the vertical direction "V" can be the same within an error range.
[0103] At the same time, such as Figure 1 and Figure 2 As shown, the MLA module 200 may include a shield 230 disposed between the input lens array 210 and the output lens array 220, the shield 230 being configured to block a portion of the light. Multiple slits may be formed in the shield 230 to allow light output from the input lens array 210 to enter the output lens array 220. However, the shape of the shield is not limited to this.
[0104] For example, a shield 230 may be provided at a position corresponding to the focal point of the output lens 222 provided in the output lens array 220.
[0105] Meanwhile, the MLA module 200 may further include: an input body portion 240 disposed between the input lens array 210 and the shield 230 and supporting the input lens array 210, and an output body portion 250 disposed between the output lens array 220 and the shield 230 and supporting the output lens array 220. However, unlike this, the MLA module 200 may not include the input body portion 240 or the output body portion 250.
[0106] Meanwhile, the lamp 10 according to this disclosure can be configured to form a low beam pattern for a vehicle.
[0107] According to the embodiments of this disclosure, lamps that perform various functions (such as low beam) can be implemented by expanding the diffusion angle of the light output from the MLA module.
[0108] As described above, although specific embodiments of this disclosure have been described above, the spirit and scope of this disclosure are not limited to these specific examples.
