[0002] This application claims priority to Korean Patent Application No. 10-2021-0124430, filed on September 17, 2021, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to a vehicle lamp, and more specifically, to a lamp for a vehicle that minimizes lens discontinuities. Background Technology

[0004] Typically, vehicles are equipped with various lights, including illumination functions that allow users to easily identify objects around the vehicle during nighttime driving, and signal functions that inform other vehicles or road users of the vehicle's driving status.

[0005] For example, vehicles include headlights and fog lights (headlights or front lights) that primarily perform lighting functions, as well as turn signals, taillights, brake lights, and side marker lights that primarily perform signaling functions. The installation references and standards for vehicle lights are stipulated by law to ensure that the lights can fully perform their functions.

[0006] Among vehicle lights, headlights that can switch between low beam and high beam modes to ensure the driver's forward visibility play a very important role in safe driving.

[0007] Meanwhile, in recent years, the importance of headlight appearance design, light distribution patterns, and headlight performance has been emphasized. Therefore, slender lenses with wide shapes have recently been used.

[0008] However, existing lenses with wide shapes are designed to be divided into regions that form short-distance and long-distance light distribution patterns. Because these regions are designed to form different focal points based on their characteristics, the shape differences within the lens regions lead to discontinuous images, potentially causing design flaws.

[0009] Therefore, in order to differentiate the design of vehicle lights, an optical system that can provide a continuous image without causing discontinuities is needed. Summary of the Invention

However, this disclosure is not limited to the embodiments described below, or the technical features of this disclosure are not limited to the described embodiments, and various modifications can be made to this disclosure without departing from its technical scope.

[0045] Reference Figures 1 to 8 The vehicle lamp 10 according to an embodiment of the present disclosure includes a light source 100 and a lens 400. Furthermore, the vehicle lamp 10 according to an embodiment of the present disclosure may also include a shielding portion 300 and a reflector array 200.

[0046] The light source unit 100 includes multiple light sources that emit light.

[0047] Here, the light source can be any element or device capable of emitting light. For example, the light source can be a light-emitting diode (LED), but this disclosure is not limited thereto; the light source can be any type of lamp, such as a laser diode, a light bulb, a halogen lamp, or a xenon lamp (HID).

[0048] The light source unit 100 may include multiple light sources, and the number and arrangement of the light sources can be determined according to the lamp design specifications. For example, multiple light sources may be arranged in an arc relative to the left / right direction. However, the arrangement of multiple light sources is not limited to this.

[0049] More specifically, the light source unit 100 may include a first light source 110 and a second light source 120.

[0050] Multiple first light sources 110 can be provided to form a first light distribution pattern. Multiple second light sources 120 can be provided to form a second light distribution pattern with characteristics different from the first light distribution pattern, and the second light sources 120 can be arranged at a position further away from the optical axis AX of the light source section 100 than the position of the first light sources 110. Here, the optical axis AX can be the optical axis AX formed by an optical system including the light source section 100 and the lens section 400.

[0051] The first light distribution pattern and the second light distribution pattern can overlap each other to form a near-light pattern, and the size of the light-emitting surface of the first light source 110 can be smaller than the size of the light-emitting surface of the second light source 120.

[0052] Here, the first light distribution pattern and the second light distribution pattern have different characteristics in that the pattern images of the light emitted by the first light source 110 and the second light source 120 and output by the lens section 400 are different. For example, this can be achieved by the different sizes of the light-emitting surfaces of the first light source 110 and the second light source 120 and the spacing between the light source and the reflector array 200.

[0053] For example, the first light distribution pattern achieved by the first light source 110 can be a light distribution pattern (hot zone) used to ensure the field of view of the central area in front (see...). Figure 4 Furthermore, the second light distribution pattern achieved by the second light source 120 can be a light distribution pattern (wide area) used to ensure visibility in the forward peripheral area and during turning (see...). Figure 5 Furthermore, the first and second light distribution modes can be combined to form a near-beam mode (see...). Figure 6 ).

[0054] Furthermore, for example, the size of the emitting surface of the first light source 110 can be smaller than the size of the emitting surface of the second light source 120. Additionally, the first light source 110 can be positioned closer to the optical axis AX than the second light source 120. That is, the second light source 120 can be positioned to the left / right outer side of the first light source 110. Therefore, the light source with the smaller emitting surface can be positioned closer to the optical axis AX.

[0055] The lens unit 400 is configured to output light emitted by the light source unit 100 to the front. The lens unit 400 includes a first lens 410 and a second lens 420. In the following text, for ease of description, the horizontal direction perpendicular to the optical axis (X-axis direction) will be referred to as the left / right direction (Y-axis direction), and the direction perpendicular to both the optical axis (X-axis direction) and the left / right direction (Y-axis direction) will be referred to as the vertical direction (Z-axis direction).

[0056] The first lens 410 can be disposed in front of the light source unit 100, and the first lens 410 can become thinner as it moves toward two opposite sides relative to the left / right direction. Specifically, both the input surface 411 and the output surface 412 of the first lens 410 can have convex spherical surfaces, so the thickness of the first lens 410 in the optical axis AX direction can become smaller as it moves further away from the optical axis AX. For example, the first lens 410 can be symmetrical in the left-right direction relative to the optical axis AX.

[0057] The second lens 420 may be positioned in front of the first lens 410, and the second lens 420 may be deflected from one end to the other relative to the left / right direction to be positioned further rearward.

[0058] Specifically, as the second lens 420 moves from one end to the other in the left / right direction, it can deflect to get closer to the light source 100. Therefore, the second lens 420 is asymmetrical in the left / right direction relative to the optical axis AX. Here, the second lens 420 can deflect continuously without any stepped portions. Because the second lens 420 is positioned at the front and constitutes the appearance of the headlight 10, the headlight 10 according to this disclosure can be differentiated in terms of design.

[0059] For example, the headlight 10 according to this disclosure can be mounted on the left and right sides of the vehicle, and the second lens 420 can move closer to the light source 100 as it moves from the center of the vehicle to the outside. That is, as the second lens 420 moves from the inside to the outside of the vehicle, it can deflect rearward.

[0060] Furthermore, the lens section 400 can form a single focal point F by the first lens 410 and the second lens 420. Therefore, discontinuities that may occur when the first lens 410 and the second lens 420 have different shapes or are stepped shapes can be prevented.

[0061] For example, when the lens portion is designed to be divided into a region for forming a first light distribution pattern and a region for forming a second light distribution pattern, the lens portion can be designed to form different focal points in each region. Therefore, boundary surfaces may be formed for these regions, potentially resulting in discontinuous images. In this case, it may lead to design defects in the lamp. Because this disclosure is designed to form a single focal point with the lens portion 400, the lens portion 400 can achieve a continuous image, thereby improving the appearance design of the lamp.

[0062] Meanwhile, the left / right width of the first lens 410 can be the same as the left / right width of the second lens 420. This ensures a continuous image from the lens section 400. However, the left / right widths of the first lens 410 and the second lens 420 are not limited to being the same; for example, the left / right width of the second lens 420 can be greater than the left / right width of the first lens 410.

[0063] The horizontal curvature of the input surface 411 of the first lens 410 may be less than the horizontal curvature of the output surface 412 of the first lens 410. Hereinafter, horizontal curvature refers to the curvature in the Y-axis direction (i.e., the left / right direction). Furthermore, vertical curvature refers to the curvature in the Z-axis direction.

[0064] Specifically, the first lens 410 can be configured such that the horizontal radius of curvature of the input surface 411 is greater than the horizontal radius of curvature of the output surface 412. Thus, because the curvature of the input surface 411 relative to the left / right direction is less than the curvature of the output surface 412, the thickness of the first lens 410 can be minimized.

[0065] Furthermore, the vertical curvature of the input surface 411 of the first lens 410 can be greater than the vertical curvature of the output surface 412 of the first lens 410.

[0066] Specifically, the first lens 410 can be configured such that the vertical radius of curvature of the input surface 411 is smaller than the vertical radius of curvature of the output surface 412. Therefore, image distortion of the first lens 410 can be minimized even at lower heights.

[0067] Furthermore, the horizontal and vertical curvatures of the input surface 411 of the first lens 410 can be different, and the horizontal and vertical curvatures of the output surface 412 of the first lens 410 can also be different. That is, the horizontal and vertical curvatures of the input surface 411 and the output surface 412 of the first lens 410 can be different. Therefore, the first lens 410 can be minimized.

[0068] Meanwhile, the horizontal curvature of the input surface 411 of the second lens 420 can be the same as the horizontal curvature of the output surface 412 of the second lens 420. Furthermore, the vertical curvature of the input surface 411 of the second lens 420 can be the same as the vertical curvature of the output surface 412 of the second lens 420.

[0069] Specifically, the first lens 410 may have optical properties that change the direction of light propagation to form a specific light distribution pattern, while the second lens 420 may be a lens that outputs light after the light passes through the first lens 410, and may be a lens that determines the external design shape of the headlight 10. Therefore, the horizontal curvature of the input surface 421 and the output surface 422 of the second lens 420 may be the same, and the vertical curvature of the input surface 421 and the output surface 422 of the second lens 420 may be the same.

[0070] Furthermore, the horizontal and vertical curvatures of the input surface 421 of the second lens 420 can be different. Similarly, the horizontal and vertical curvatures of the output surface 422 of the second lens 420 can be different. In other words, the horizontal and vertical curvatures of the input surface 421 and the output surface 422 of the second lens 420 can be different.

[0071] The thickness of the second lens 420 in the direction from the input surface 421 to the output surface 422 can be uniform over the entire area. As described above, because the second lens 420 constituting the appearance of the lamp is uniform over the entire area, the appearance of the vehicle lamp 10 according to this disclosure can achieve a continuous image.

[0072] Here, uniform thickness does not simply mean that the thickness of the second lens 420 is exactly the same throughout the entire region in the direction from the input surface 421 to the output surface 422. For example, a thickness difference within tolerance (e.g., within about 2 mm) caused by a person skilled in the art during manufacturing, as described in this disclosure, can be considered a uniform thickness.

[0073] Because the first lens 410 and the second lens 420 have the aforementioned curvature, the size of the lenses can be minimized, thus enabling continuous images and making the headlight 10 smaller.

[0074] Meanwhile, as described above, the light source unit 100 may include: a first light source 110, which forms a first light distribution pattern (hot zone) to ensure the field of vision in the central area in front; and a second light source 120, which forms a second light distribution pattern (wide zone) to ensure the field of vision and visibility in the peripheral area in front. In addition, the first light distribution pattern and the second light distribution pattern may overlap each other to form a low beam pattern.

[0075] Here, the size of the light-emitting surface of the first light source 110 can be smaller than the size of the light-emitting surface of the second light source 120.

[0076] That is, the size of the first light source 110 used to form the first light distribution pattern (hot zone) can be smaller than the size of the second light source 120 used to form the second light distribution pattern (wide zone). Therefore, the first light source 110, which has a small luminous surface, can be positioned closer to the optical axis AX, and the second light source 120, which has a large luminous surface, can be positioned further away from the optical axis AX. By adjusting the size and arrangement of the light sources, the first light distribution pattern and the second light distribution pattern can be formed.

[0077] Additionally, this disclosure may also include a reflector array 200. In the reflector array 200, multiple reflectors configured to reflect light emitted by multiple light sources may be coupled to each other.

[0078] For example, multiple light sources can be arranged in an arc relative to the left / right direction. Furthermore, in the reflector array 200, reflectors arranged further away from the optical axis can be closer to the lens section 400.

[0079] Here, the reflector array 200 may include: a plurality of first reflectors 210 that reflect light emitted by a plurality of first light sources 110; and a plurality of second reflectors 220 that reflect light emitted by a plurality of second light sources 120. Specifically, the first reflectors 210 may form a first light distribution pattern together with the first light sources 110, and the second reflectors 220 may form a second light distribution pattern together with the second light sources 120.

[0080] Here, for reference Figure 8 The first reflection distance L1 (i.e., the distance from the emitting surface of the first light source 110 to the reflecting surface of the first reflector 210) is greater than the second reflection distance L2 (i.e., the distance from the emitting surface of the second light source 120 to the reflecting surface of the second reflector 220). Specifically, the first reflector 210 used to form the first light distribution pattern can be configured such that its reflecting surface is further away from the light source than the second reflector 220 used to form the second light distribution pattern. Therefore, the first light distribution pattern and the second light distribution pattern can have different characteristics.

[0081] At the same time, refer to Figure 1 and Figure 2 The first lens 410 and the second lens 420 may include inclined surfaces on their upper and lower surfaces such that the upper and lower surfaces are convex.

[0082] Specifically, the upper surface of the first lens 410 may include: a first upwardly inclined surface 415, which extends from the upper end of the input surface 411 and is inclined upward; and a second upwardly inclined surface 416, which is inclined downward from the first upwardly inclined surface 415 toward the output surface 412. Specifically, the lower surface of the first lens 410 may include: a first downwardly inclined surface 417, which extends from the lower end of the input surface 411 and is inclined downward; and a second downwardly inclined surface 418, which is inclined upward from the first downwardly inclined surface 417 toward the output surface 412.

[0083] Therefore, the inclined surface can be applied to the upper and lower surfaces of the first lens 410.

[0084] Furthermore, the upper surface of the second lens 420 may include: a first upper inclined surface 425, which extends from the upper end of the input surface 421 and slopes upward; and a second upper inclined surface 426, which slopes downward from the first upper inclined surface 425 toward the output surface 422. Specifically, the lower surface of the second lens 420 may include: a first lower inclined surface 427, which extends from the lower end of the input surface 421 and slopes downward; and a second lower inclined surface 428, which slopes upward from the first lower inclined surface 427 toward the output surface 422.

[0085] Therefore, a beveled surface can be applied to the upper and lower surfaces of the second lens 420. In this way, by applying a bevel at a specific angle using the beveled surfaces formed on the upper and lower surfaces of the first lens 410 and the second lens 420, light leakage on the upper and lower surfaces of the first lens 410 and the second lens 420 can be minimized. Specifically, because the first lens 410 and the second lens 420 are thick, light leakage caused by surface reflection can be minimized when a bevel is applied to their upper and lower surfaces.

[0086] For example, as in accordance with Figure 9 and Figure 10 In the lens section 400' of the comparative example shown, when the upper surface 415' and lower surface 417' of the first lens 410' and the upper surface 425' and lower surface 427' of the second lens 420' are formed to be flat, surface reflection caused by the large thickness of the first lens 410' and the second lens 420' may cause a lot of light leakage. Figure 10 The dashed area is caused by light leakage. Light leakage can reduce the quality of the headlights.

[0087] Therefore, this disclosure can correct light leakage and improve product quality by forming convex inclined surfaces on the upper and lower surfaces of the first lens 410 and the second lens 420.

[0088] Additionally, this disclosure may include a shielding portion 300. The shielding portion 300 may be disposed between the light source portion 100 and the lens portion 400, and may be configured to shield a portion of the light emitted by the light source portion 100. Here, the shielding portion 300 may be disposed at the focal point "F" of the lens portion 400. Furthermore, due to the shape of the shielding portion, a cutoff line can be formed in the low beam mode.

[0089] According to the embodiments of the present disclosure, since the first lens and the second lens form a single focal point and the second lens that forms the appearance of the lamp is continuous, the discontinuity caused by the stepped shape in the elongated lamp can be minimized.

[0090] Accordingly, according to embodiments of this disclosure, since the continuity of the lens can be achieved in the elongated height portion, design differentiation may exist, thereby enhancing the competitiveness of the product.

[0091] Although specific embodiments of the present disclosure have been described so far, the spirit and scope of the present disclosure are not limited to the specific embodiments, and various corrections and modifications can be made by those skilled in the art to which the present disclosure pertains without altering the essence of the present disclosure as claimed in the claims.
