[0038] In addition, when describing the components of the embodiments of the present disclosure, terms (e.g., first, second, "A", "B", (a) and (b)) may be used. These terms are only used to distinguish the components, and the nature, order and sequence of the corresponding components are not limited by these terms. It should be understood that when describing that a component is "input to" or "output from" another component, the former component can be directly input to or output from the latter component, but a third component can be "input" or "output" between the two components.

[0039] Hereinafter, a lamp 1 for a vehicle (hereinafter referred to as a “lamp”) according to the present disclosure will be described with reference to the accompanying drawings.

[0040] refer to Figure 1 The lamp 1 according to the present disclosure may be a headlamp for implementing an adaptive driving beam (ADB). The lamp 1 may be disposed at the front side of a vehicle and may ensure visibility for a user. The lamp 1 may include an optical module 10 and a controller 20.

[0041] The optical module 10 according to the first embodiment of the present disclosure may form a beam segment. A beam segment may refer to a part that forms a part of a beam pattern. In the present disclosure, as an example, a beam pattern may refer to a high-beam light distribution pattern. The optical module 10 may include a light source 100a, a collimator 200, and an MLA module 300.

[0042] The light source 100a may output light in a first direction (e.g., a forward direction). For example, the light source 100a may be a light emitting diode (LED). However, the present disclosure is not limited to this example, and the light source 100a may be provided with various devices that may output light in the first direction.

[0043] In addition, the optical axis of the light source 100a may be referred to as a first optical axis X1. The first optical axis X1 may be defined as an imaginary line passing through the center of the light source 100a and extending in a first direction (eg, a forward direction). The light source 100a may have a symmetrical shape with respect to the first optical axis X1.

[0044] The collimator 200 may convert the input light into parallel light, and then may output the light forward. For example, the light output from the light source 100a may be input to the rear surface of the collimator 200. The rear surface of the collimator 200 may be referred to as the light input surface of the collimator 200. The rear surface of the collimator 200 may have a shape that bulges backward.

For example, the collimator 200 may be arranged on the front side of the light source 100a.

[0045] In addition, the optical axis of the collimator 200 may be referred to as the second optical axis X2. The second optical axis X2 may be defined as an imaginary line that passes through the center of the collimator 200 and extends in a first direction (e.g., a forward direction). The collimator 200 may have a shape that is symmetrical with respect to the second optical axis X2. In addition, the first optical axis X1 may be parallel to the second optical axis X2. For example, the first optical axis X1 and the second optical axis X2 may coincide with each other. In other words, the first optical axis X1 and the second optical axis X2 may form the same imaginary line.

[0046] In addition, the light source 100 a and the collimator 200 may be referred to as a first optical system. In other words, the first optical system may be understood as a concept including the light source 100 a and the collimator 200 .

The optical axis of the input lens 311a may be referred to as an input optical axis X31. The input optical axis X31 may be defined as an imaginary line passing through the center of the input lens 311a and extending in the forward / backward direction "D". In a more detailed example, the input optical axis X31 may be defined as an imaginary line passing through the vertical (V) center and the horizontal center of the input lens 311a.

[0050] The input lens 311a may have a symmetrical shape with respect to the input optical axis X31. The input lens 311a may be provided as an aspherical lens. In addition, a plurality of input optical axes X31 may be provided to correspond to the plurality of input lenses 311a, respectively.

[0051] The output lens array 320 may output light input to the input lens array 310a to the outside. The output lens array 320 may define the rear side of the MLA module 300. The output lens array 320 and the input lens array 310a may be integrally formed. For example, the input lens array 310a and the output lens array 320 may be injection molded with a single component. In other words, the MLA module 300 may be manufactured by a single injection molding process. In this way, because the MLA module 300 according to the present disclosure may be manufactured by a single injection molding process, the complexity of the conventional process required to manufacture and couple multiple components may be resolved. The output lens array 320 may include a plurality of output lenses 321.

[0052] Each output lens 321 may have a shape that bulges forward. In addition, as an example, the plurality of output lenses 321 may be arranged to have a grid pattern along a direction perpendicular to the forward / backward direction "D" (the leftward / rightward direction "W" and the vertical direction "V"). All of the plurality of output lenses 321 may be the same single lens.

In addition, the width of the output lens 321 in the vertical direction "V" can be the same as the width of the input lens 311a in the vertical direction "V".

[0056] The optical axis of the output lens 321 may be referred to as an output optical axis X32. The output optical axis X32 may be defined as a virtual line that passes through the center of the output lens 321 and extends in the forward / rearward direction "D". In more detail, the output optical axis X32 may refer to a virtual line that passes through the vertical (V) center and the horizontal center of the output lens 321.

[0057] The output lens 321 may have a symmetrical shape with respect to the output optical axis X32. The output lens 321 may be provided as an aspherical lens. A plurality of output optical axes X32 may be provided to correspond to the plurality of output lenses 321, respectively.

In addition, multiple input lenses 311a may correspond to multiple output lenses 321 in a one-to-one relationship. For example, multiple output optical axes X32 may correspond to multiple input optical axes X31 in a one-to-one relationship. In a more detailed example, all multiple output optical axes X32 and all input optical axes X31 may coincide with each other.

[0059] In addition, return reference Figure 2 , the horizontal curvature of the input lens 311a and the horizontal curvature of the output lens 321 may be the same. The horizontal direction may be defined as a direction including the left / right direction "W" and the forward / backward direction "D" and perpendicular to the vertical direction "V". The horizontal direction curvature of the input lens 311a may refer to the curvature defined by the input lens 311a when the input lens 311a is observed in the vertical direction "V". The horizontal direction curvature of the output lens 321 may refer to the curvature defined by the output lens 321 when the output lens 321 is observed in the vertical direction "V".

[0060] In addition, return reference Figure 3 and Figure 4 , the vertical (V) curvature of the input lens 311a may be the same as the vertical (V) curvature of the output lens 321.

[0079] In addition, the radius of curvature of any portion of the input lens 311b may be the same as the radius of curvature of the output lens 321. For example, the vertical (V) radius of curvature of any portion of the input lens 311b may be the same as the vertical (V) radius of curvature of the output lens 321. In a more detailed example, any portion of the input lens 311b may refer to the upper region 311b-1.

The description of the light source 100a, the collimator 200, and the MLA module 300 of the first optical module 11 is replaced by the description of the light source 100a, the collimator 200, and the MLA module 300 according to the third embodiment.

[0093] The second optical module 12 may include a light source 100a, a collimator 200, and an MLA module 300. The description of the MLA module 300 of the second optical module 12 is replaced by the description of the MLA module 300 according to the third embodiment.

[0094] The first optical axis X1 and the second optical axis X2 of the second optical module 12 may coincide with each other. In addition, the first optical axis X1 and the output optical axis X32 of the second optical module 12 may not be parallel to each other. For example, when the second optical module 12 is observed in the vertical direction "V", the first optical axis X1 and the output optical axis X32 may be oriented to be non-parallel to each other. In other words, when the second optical module 12 is observed in the vertical direction "V", the dotted line extending along the first optical axis X1 and the dotted line extending along the output optical axis X32 may cross at one point.

[0095] The second optical module 12 may be disposed at the rear side of the front end of the first optical module 11. In addition, the second optical module 12 may be disposed at one side of the first optical module 11 in the left / right direction "W". Fig.14 and Fig.15 , the second optical module 12 of the right lamp as the lamp 1 disposed on the right side of the vehicle can be disposed on the right side of the first optical module 11. The right lamp can define the left area of ​​the beam pattern. In addition, Fig.14 is a view showing the appearance of the right lamp.

[0096] However, the present disclosure is not limited to this example, and although not shown in the drawings, the second optical module of the left lamp as a lamp disposed on the left side of the vehicle may be disposed on the left side of the first optical module. In addition, the left lamp may define a right area of ​​the beam pattern.

[0097] Hereinafter, the description will be made with reference to when the second optical module 12 is provided in the right lamp. Fig.14 The second optical module 12 may include: a 2-1st optical module 12-1 and a 2-2nd optical module 12-2.

[0098] The first optical axis X1 and the output optical axis X32 of the 2-1st optical module 12-1 may define a first angle a1. The output optical axis X32 of the 2-1st optical module 12-1 may extend in the forward / backward direction, and the first optical axis X1 of the 2-1st optical module 12-1 may extend to be inclined to the right with respect to the forward / backward direction. In addition, with respect to the left / right direction "W", the 2-1st optical module 12-1 may be disposed between the first optical module 11 and the 2-2nd optical module 12-2.

[0099] The first optical axis X1 and the output optical axis X32 of the 2-2nd optical module 12-2 may define a second angle a2. The output optical axis X32 of the 2-2nd optical module 12-2 may extend in the forward / backward direction, and the first optical axis X1 of the 2-2nd optical module 12-2 may extend to be tilted to the right relative to the forward / backward direction. In addition, the second angle a2 may be greater than the first angle a1. In other words, the degree to which the first optical axis X1 of the 2-2nd optical module 12-2 is tilted to the right relative to the forward / backward direction may be greater than the degree to which the first optical axis X1 of the 2-1st optical module 12-1 is tilted to the right relative to the forward / backward direction.

[0100] In addition, the first optical module 11, the 2-1st optical module 12-1 and the 2-2nd optical module 12-2 can be arranged sequentially along the right direction. In addition, the beam segments formed by the first optical module 11, the 2-1st optical module 12-1 and the 2-2nd optical module 12-2 can be referred to as a central segment, a first peripheral segment and a second peripheral segment.

[0101] Fig.15 1 is a view showing a beam pattern formed by the right lamp when the controller 20 turns on the light source 100a of the first optical module 11, the light source 100a of the 2-1st optical module 12-1, and the light source 100a of the 2-2nd optical module 12-2. Fig.15 is a view showing a beam pattern when a central segment, a first peripheral segment, and a second peripheral segment are all formed.

[0102] Fig.16 1 is a view showing a beam pattern formed by the right lamp when the controller 20 turns on the light source 100a of the first optical module 11 and the light source 100a of the 2-2nd optical module 12-2 and turns off the light source 100a of the 2-1st optical module 12-1. In other words, Fig.16 is a view showing a beam pattern when a central segment and a second peripheral segment are formed and a first peripheral segment is not formed.

[0103] The optical module according to the present disclosure includes a microlens array, which can realize an adaptive drive beam (ADB) without separately including a shielding member, thereby solving the problem of a complicated process for manufacturing the microlens array and a complicated manufacturing scheme thereof.
