Description

Technical Field

[0001] The present invention relates to a lamp module and a vehicle lamp including the same, and more particularly to a lamp module capable of forming an optimal beam pattern while achieving a slim design and a vehicle lamp including the same. Background Art

[0002] Typically, a vehicle is equipped with a variety of lamps having a lighting function for easily identifying objects around the vehicle during nighttime driving, and a signaling function for notifying other vehicles or pedestrians of the vehicle's driving status.

[0003] For example, headlights and fog lights are mainly used for lighting functions, while turn signals, taillights and brake lights are mainly used for signal functions. The setting standards and specifications of each lamp are stipulated by laws and regulations so that the functions of each lamp can be fully utilized.

[0004] Among them, the headlights irradiate light in the direction of travel of the vehicle, thereby playing a role in ensuring the driver's forward field of vision.

[0005] For example, in order to prevent glare for drivers of vehicles ahead, such as those in front or oncoming vehicles, the headlights direct light downward based on the cut-off line, thereby forming a low-beam pattern that ensures a wide field of view at a short distance in front of the vehicle, or a high-beam pattern that ensures a long field of view at a long distance in front of the vehicle.

[0006] At this time, the low-beam pattern blocks a portion of light generated from the light source to form a cut-off line, so light loss occurs and light efficiency is reduced.

[0007] Furthermore, in recent years, not only the functional aspect of headlights, which is to help drivers drive safely by ensuring their field of vision, but also the aesthetic aspect of consumers, which is enhanced by exterior design, has a significant impact on vehicle purchase decisions.

[0008] Therefore, there is a need for a solution that can achieve a slim appearance design so that consumers can feel the beauty, improve light efficiency by reducing light loss, and form an optimal light beam pattern.

[0009]

[0020] The light incident on the second incident module travels in a manner of being focused at the rear side of the emission portion, and the lower side reflection portion can be formed so that at least one of the first reflection surface and the second reflection surface has a curved surface shape, so that the light incident on the second incident module is converted into parallel light.

[0021] The second incident modules may be formed to be symmetrical with each other so as to have the same light concentration as the first incident modules.

[0022] The guide member may further include a shielding portion having a front end located at a rear focus of the emitting portion to block a portion of the light traveling to the emitting portion, thereby forming a cut-off line of the beam pattern.

[0068] Hereinafter, the present invention will be described with reference to the accompanying drawings for illustrating a lamp module and a vehicle lamp including the lamp module according to an embodiment of the present invention.

[0070] Reference Figures 1 to 7 The lamp module 1000 according to the embodiment of the present invention may include a light source portion 1100 and a light guide portion 1200 .

[0071] In an embodiment of the present invention, the case where the lamp module 1000 is used as a headlamp to ensure the vehicle's forward field of vision by irradiating light in the direction of travel of the vehicle when the vehicle is traveling at night or in a dark place such as a tunnel is described as an example, but the present invention is not limited to this. The lamp module 1000 of the present invention can be used not only as a headlamp, but also as a taillight, brake light, daytime running light, turn signal light, fog light, reversing light, position marker light and other various lamps provided on the vehicle. The lamp module 1000 of the present invention can be used for any one of the above-mentioned multiple purposes, and can also be used for two or more purposes at the same time.

[0072] In addition, in an embodiment of the present invention, the X-axis direction is used as the left-right direction to represent the vehicle width direction, the Y-axis direction is used as the driving direction to represent the front-back direction (forward or backward), and the Z-axis direction is used as the up-down direction to represent the vehicle height direction. However, the present invention is not limited thereto. According to the position or direction in which the lamp module 1000 of the present invention is set, the actual directions represented by the X-axis, Y-axis, and Z-axis may be different.

[0073] When the lamp module 1000 of the present invention is used as a headlamp, light is irradiated to the lower side based on the light-dark cutoff line to prevent glare to the driver of the preceding vehicle, such as the preceding vehicle or the oncoming vehicle, thereby forming at least one of a low beam pattern ensuring a wide field of view at a short distance in front of the vehicle and a high beam pattern ensuring a long field of view at a long distance in front of the vehicle.

[0074] In the following embodiments of the present invention, Figure 8 As shown, the case where the lamp module 1000 of the present invention forms a low beam pattern LP that irradiates light downward based on the cut-off line CL is described as an example, and Figure 8 The low beam pattern LP is described as an example of a beam pattern formed by irradiating light from the lamp module 1000 of the present invention onto a screen located at a set distance in front of a vehicle.

[0075] In an embodiment of the present invention, the cut-off line CL is formed at a position where the first line CL1 corresponding to the driving lane is higher than the second line CL2 corresponding to the opposite lane, so that the first line CL1 and the second line CL2 have a step difference due to the inclined line CL0, so that the light irradiation distance of the driving lane is relatively longer. However, this is merely an example to help understand the present invention and is not limited to this. The cut-off line CL can be formed to have the same height as a whole. In this case, the inclined line CL0 can be omitted and the first line CL1 and the second line CL2 can be formed as a single line without a step difference.

[0076] In addition, in an embodiment of the present invention, the case where a low beam pattern LP is formed by a single lamp module 1000 is used as an example for explanation, but this is merely an example to help understand the present invention and is not limited to this. When more than two lamp modules are used, a low beam pattern LP can be formed by synthesizing different light distribution patterns formed by each lamp module.

[0077] For example, in the case of forming a low beam pattern LP by means of two or more lamp modules, any one of the two or more lamp modules forms a light distribution pattern corresponding to a high illumination area with relatively high brightness to ensure a sufficient field of view distance in the low beam pattern LP, and the other is used to ensure a wide field of view range in front of the vehicle. Although the brightness is lower than that of the high illumination area, a light distribution pattern corresponding to an extended area formed to diffuse in at least one of the left and right directions and the up and down directions can be formed based on the high illumination area.

[0078] The light source unit 1100 may include at least one light source that generates light of a quantity or color suitable for the purpose of the lamp module 1000 of the present invention.

[0079] In the embodiments of the present invention, a case where a semiconductor light-emitting element such as a light-emitting diode (LED) is used as at least one light source is described as an example, but the invention is not limited thereto. Not only an LED but also various types of light sources such as a laser diode (LD) or a light bulb can be used as the at least one light source. Furthermore, depending on the type of light source, optical elements such as reflectors, phosphors, lenses, prisms, etc. can be used to change light properties such as brightness, path, color, etc. of the light.

[0080] The light guide portion 1200 can be located in front of the light source portion 1100 to guide at least a portion of the light incident from the light source portion 1100 to be emitted forward and form at least one beam pattern. To this end, the light source portion 1100 can be configured so that the light emitting surface or light emitting area faces forward.

[0081] At this time, the light guide portion 1200 is located in front of the light source portion 1100, which means the positions of the light source portion 1100 and the light guide portion 1200 assuming that the direction of light irradiated from the lamp module 1000 of the present invention is forward. According to the position or direction in which the lamp module 1000 of the present invention is set, the direction actually represented by the forward direction may be changed.

[0082] The light guide portion 1200 may include an incident portion 1210 and a guide member 1220 .

[0083] The incident portion 1210 can be incident on the light emitted from the light source portion 1100, and at least a portion of the light incident on the incident portion 1210 can be guided by the guide component 1220 to be emitted through the emission portion 1221 formed at the front end portion of the guide component 1220, thereby forming a beam pattern suitable for the purpose of the lamp module 1000 of the present invention.

[0084] At this time, the incident surface of the incident portion 1210 and the guide component 1220 can be formed integrally with each other. Since the emission portion 1221 is formed at the front end portion of the guide component 1220, the assembly process can be simplified and the cost can be reduced by reducing the number of components compared to the case where the incident portion 1210 and the guide component 1220 are formed and assembled separately.

[0085] The incident portion 1210 is parallel to the optical axis Ax (i.e., the front-to-back direction) of the emitting portion 1221 and is based on the axis passing through the rear focus F of the emitting portion 1221, so that the upper area and the lower area can have different concentrations from each other, or can have the same concentration.

[0086] At this time, the rear focus F of the emitting portion 1221 may be a point, a line, a surface, a space, or a combination thereof according to the actual light focusing area.

[0087] The light incident into the upper area and the lower area of ​​the incident portion 1210 has different degrees of convergence from each other, which includes not only the situation where the light is focused at different focal points from each other, but also the situation where the light incident into any one of the upper area and the lower area of ​​the incident portion 1210 is focused to the focal point and the light incident into the other area travels as parallel light.

[0088] Figure 9 is a rear view showing an incident portion of a light guide portion according to an embodiment of the present invention, Figure 10 is a side view showing an incident portion of a light guide portion according to an embodiment of the present invention, Figure 11 1 is a plan view showing an incident portion of a light guide portion according to an embodiment of the present invention.

[0089] Reference Figures 9 to 11According to an embodiment of the present invention, the incident portions 1210 may be formed asymmetrically so that light incident on the upper and lower regions with respect to the optical axis Ax of the emission portion 1221 has different concentrations.

[0090] In an embodiment of the present invention, the case where the optical axis Ax' of the light source unit 1100 is made to coincide with the optical axis Ax of the emission unit 1221 is described as an example, but the present invention is not limited thereto. Depending on the light distribution characteristics required in the beam pattern formed by the lamp module 1000 of the present invention, for example, the position, shape, size, brightness, etc. of the light irradiated area, the optical axis Ax' of the light source unit 1100 and the optical axis Ax of the emission unit 1221 may also be made to not coincide with each other.

[0091] At this time, when the light source unit 1100 is configured as a single light source, the axis passing vertically through the center of the light-emitting surface of the single light source can be understood as the optical axis Ax' of the light source unit 1100. When the light source unit 1100 is configured as multiple light sources, the axis passing vertically through the center of the light-emitting area formed by the light-emitting surface of each of the multiple light sources can be understood as the optical axis Ax' of the light source unit 1100.

[0092] The incident portion 1210 may include a first incident module 1210a located at the upper portion with the optical axis Ax of the emitting portion 1221 as a reference, and a second incident module 1210b located at the lower portion with the optical axis Ax of the emitting portion 1221 as a reference. Moreover, taking the optical axis Ax of the emitting portion 1221 as a reference, making the upper and lower portions of the incident portion 1210 asymmetrical to each other can be understood as making the first incident module 1210a and the second incident module 1210b asymmetrical to each other.

[0093] The incident portion 1210 may include a central plane 1211 centered on the optical axis Ax of the emitting portion 1221 , a protruding surface 1212 protruding from an edge of the central plane 1211 toward the light source portion 1100 , and a reflecting surface 1213 reflecting light incident on the protruding surface 1212 to travel forward.

[0094] At this time, the first incident module 1210a can be composed of the central plane 1211, the protruding surface 1212 and the area located at the upper part of the reflecting surface 1213 with the optical axis Ax of the emitting part 1221 as the reference. Similarly, the second incident module 1210b can be composed of the central plane 1211, the protruding surface 1212 and the area located at the lower part of the reflecting surface 1213 with the optical axis Ax of the emitting part 1221 as the reference.

[0095] The case where the first incident module 1210a and the second incident module 1210b are formed asymmetrically with each other may include a case where the first incident module 1210a and the second incident module 1210b have different lengths from each other in at least one direction of the up-down direction and the left-right direction and a case where they have different curvatures from each other.

[0096] The situation in which the first incident module 1210a and the second incident module 1210b have different lengths from each other along at least one direction may include the situation in which at least one of the center surface 1211, the protruding surface 1212 and the reflecting surface 1213 has different lengths from each other in the upper area and the lower area with the optical axis Ax of the emitting portion 1221 as the reference.

[0097] In addition, the situation in which the first incident module 1210a and the second incident module 1210b have different curvatures from each other along at least one direction may include the situation in which at least one of the center surface 1211, the protruding surface 1212 and the reflecting surface 1213 has different curvatures from each other in the upper area and the lower area with the optical axis Ax of the emitting portion 1221 as the reference along at least one direction.

[0098] In an embodiment of the present invention, an example is given in which the curvature R11 in the vertical direction and the curvature R21 in the horizontal direction of the first incident module 1210a are respectively greater than the curvature R12 in the vertical direction and the curvature R22 in the horizontal direction of the second incident module 1210b. This is to enable the light incident on the first incident module 1210a to be focused at the rear focus F of the emission portion 1221 or near it, and to enable the light incident on the second incident module 1210b to travel as parallel light that is approximately parallel to the optical axis Ax of the emission portion 1221. A detailed explanation of this will be given later.

[0099] As described above, when the curvature R11 in the up-down direction and the curvature R21 in the left-right direction of the first incident module 1210a are respectively greater than the curvature R12 in the up-down direction and the curvature R22 in the left-right direction of the second incident module 1210b, due to the curvature difference between the first incident module 1210a and the second incident module 1210b, the length d11 in the up-down direction of the first incident module 1210a and the length d21 in the left-right direction of the first incident module 1210a can be formed to be smaller than the length d12 in the up-down direction and the length d22 in the left-right direction of the second incident module 1210b, respectively.

[0100] In an embodiment of the present invention, an example is given in which the length in the up-down direction and the length in the left-right direction of each of the first incident module 1210a and the second incident module 1210b are determined by the curvature of the first incident module 1210a and the second incident module 1210b. However, this is merely an example to help understand the present invention and is not limited to this. Even if the second incident module 1210b has a smaller curvature than the first incident module 1210a in the up-down direction, the second incident module 1210b may also have a smaller length than the first incident module 1210a in the up-down direction, and even if the second incident module 1210b has a smaller curvature than the first incident module 1210a in the left-right direction, the second incident module 1210b may also have a smaller length than the first incident module 1210a in the left-right direction.

[0101] For example, when at least one of the center surface 1211, the protruding surface 1212, and the reflecting surface 1213 is formed so that the upper and lower parts have a step difference based on the optical axis Ax, the lengths in the left-right direction and the up-down direction of the first incident module 1210a and the second incident module 1210b may not depend on the curvature of the first incident module 1210a and the second incident module 1210b.

[0102] For the sake of convenience, the above Figure 10 and Figure 11 This is an example to illustrate the difference in curvature between the first incident module 1210a and the second incident module 1210b, and the curvature of the areas located in the upper and lower parts respectively based on the optical axis Ax of the emission part 1221 in the reflecting surface 1213 is used as an example to illustrate the situation, and the same applies to the center surface 1211 and the protruding surface 1212.

[0103] The guide member 1220 may guide at least a portion of the light incident into the incident portion 1210 to be transmitted to the emission portion 1221 .

[0104] The light incident on the first incident module 1210a can be transmitted through the guiding component 1220 according to the curvature or angle formed by at least one of the central surface 1211, the protruding surface 1212 and the reflecting surface 1213, so that it can be focused at the rear focus F of the emission portion 1221 or near it. In an embodiment of the present invention, the case where the emission portion 1221 has a shape that protrudes forward for focusing is taken as an example, but this is only an example to help understand the present invention and is not limited to this. According to the light distribution characteristics required in the beam pattern formed by the lamp module 1000 of the present invention, the emission portion 1221 can have a convex or concave shape relative to the front.

[0105] In addition, the emitting portion 1221 can be constructed as a plurality of emitting surfaces 1221a, so as to enable easier path control of the light emitted from the lamp module 1000 of the present invention, and is not limited thereto. Depending on the light distribution characteristics required in the beam pattern formed by the lamp module 1000 of the present invention, the emitting portion 1221 can also be formed as a continuous single surface without a step difference.

[0106] In other words, when the emission portion 1221 is configured as a plurality of emission surfaces 1221 a , the light path emitted from each point of the emission portion 1221 can be simplified compared to when the emission portion 1221 is configured as a single surface.

[0107] At this time, any one of the multiple emission surfaces 1221a can be different from another in at least one of the curvature, angle, and size, so that the curvature, angle, size, etc. of each of the multiple emission surfaces 1221a can change according to the travel path of the light emitted through each emission surface.

[0108] In the embodiment of the present invention, the case where the plurality of emission surfaces 1221a are gradually positioned rearward from one side to the other in the left-right direction is described as an example, but this is to form the emission portion 1221 in a manner corresponding to the main body line of the vehicle.

[0109] That is, the lamp module 1000 of the present invention is housed in a space formed by a lamp housing (not shown) and a cover lens (not shown) coupled to the lamp housing, and a plurality of emission surfaces 1221a are gradually positioned rearward from one side to the other in the left-right direction, so that the emission portion 1221 is formed according to the shape of the cover lens (i.e., the outer lens) forming a portion of the main body line of the vehicle, and the position of each of the plurality of emission surfaces 1221a can vary according to the shape of the cover lens.

[0110] In addition, the guide member 1220 can guide the light incident on the second incident module 1210 b to move from the lower side to the upper side with reference to the optical axis Ax of the emission portion 1221 , and then move forward toward the emission portion 1221 .

[0111] The guide member 1220 may include a lower reflective portion 1222 located at a lower side with respect to the optical axis Ax of the emission portion 1221 , and an upper reflective portion 1223 located at an upper side with respect to the optical axis Ax of the emission portion 1221 .

[0112] The lower reflective portion 1222 may include a first reflective surface 1222a for reflecting light incident on the second incident module 1210b toward the side, and a second reflective surface 1222b for reflecting the light reflected toward the side by the first reflective surface 1222a toward the upper side.

[0113] At this time, the lower side reflection part 1222 can be formed to be symmetrical with each other in the left and right directions based on the optical axis Ax of the emitting part 1221, thereby making the first reflection surface 1222a and the second reflection surface 1222b respectively formed on both sides based on the optical axis Ax of the emitting part 1221.

[0114] The first reflecting surface 1222a is formed to extend along the front-to-back direction, and is inclined in a manner that the distance to the side from the optical axis Ax of the emitting portion 1221 gradually increases from the rear end to the front end, so that the light incident on the second incident module 1210b is reflected laterally. The second reflecting surface 1222b can be located to the side of the first reflecting surface 1222a and is inclined in a manner that the distance to the side from the optical axis Ax of the emitting portion 1221 gradually increases from the lower end to the upper end, so that the light reflected to the side by the first reflecting surface 1222a moves upward.

[0115] The upper side reflection portion 1223 can reflect the light reflected to the upper side by the second reflection surface 1222b forward so as to focus the light at the rear focus F of the emitting portion 1221 or in the vicinity thereof. Since the lower side reflection portion 1222 is formed symmetrically with respect to each other in the left and right directions with respect to the optical axis Ax of the emitting portion 1221, the upper side reflection portion 1223 can be formed on both sides with respect to the optical axis Ax of the emitting portion 1221.

[0116] At this time, the upper side reflection portion 1223 can be formed to have a curved shape, so that the light reflected to the upper side by the second reflection surface 1222b is focused at the rear focus F of the emission portion 1221 or near it. In this case, the light reflected to the upper side reflection portion 1223 by the lower side reflection portion 1222 needs to travel in the form of parallel light.

[0117] As described above, the lower reflective portion 1222 and the upper reflective portion 1223 are located in front of the incident portion 1210 , so that light incident on the second incident module 1210 b is reflected by the lower reflective portion 1222 and the upper reflective portion 1223 and travels to the emitting portion 1221 .

[0118] In addition, the guide component 1220 may include a shielding portion 1224 with its front end located at the rear focus F of the emitting portion 1221, and an edge portion E may be formed at the front end of the shielding portion 1224, which is formed to extend in the left-right direction and form a light-dark cutoff line of the beam pattern.

[0119] In other words, the edge portion E can play the role of forming the above Figure 8 The edge portion E may include an inclined edge E0 forming the inclined line CL0, a first edge E1 forming the first line CL1 of the cut-off line CL, and a second edge E2 forming the second line CL2 of the cut-off line CL.

[0120] In the embodiment of the present invention, the inclined edge E0 is to make the first edge E1 and the second edge E2 have a step difference in the vertical direction so that the above Figure 8 The first line CL1 and the second line CL2 of the cut-off line CL are formed at different heights in the up-down direction, but are not limited thereto. Figure 8 When the first line CL1 and the second line CL2 of the cut-off line CL are formed as one line without a step difference, as shown in FIG. Figure 12 As shown, the first edge E1 and the second edge E2 may be formed as one edge without a step difference, in which case the inclined edge E0 may be omitted.

[0121] In addition, in an embodiment of the present invention, the light incident on the first incident module 1210a is focused at the rear focus F of the emission portion 1221 or near it, and the light incident on the second incident module 1210b is reflected by the lower reflection portion 1222 and the upper reflection portion 1223 to adjust the light path in order to prevent the light incident on the second incident module 1210b from being blocked by the shielding portion 1224 and causing light loss.

[0122] In other words, the light incident on the first incident module 1210a is adjusted by adjusting the curvature or angle of the upper region with the optical axis Ax of the emitting portion 1221 as a reference among the central surface 1211, the protruding surface 1212 and the reflecting surface 1213, so that even when the light is focused at or near the rear focus F of the emitting portion 1221, it will not be interfered by the shielding portion 1224. On the contrary, when the light incident on the second incident module 1210b is focused at or near the rear focus F of the emitting portion 1221 among the central surface 1211, the protruding surface 1212 and the reflecting surface 1213, it will not be interfered by the shielding portion 1224. When the curvature or angle of the area located at the bottom is adjusted based on the optical axis Ax, interference may be caused by the blocking of the shielding part 1224. In this case, light loss may occur due to the blocking of the light traveling to the emission part 1221. Therefore, the light incident on the second incident module 1210b can travel along a path that will not be interfered with by the shielding part 1224 via the lower side reflection part 1222 and the upper side reflection part 1223, thereby preventing light loss caused by the light blocked in order to form the light-dark cut-off line CL.

[0123] Figure 13 and Figure 14 is a schematic diagram illustrating a path of light incident on a first incident module according to an embodiment of the present invention.

[0124] Reference Figure 13 and Figure 14The light L1 incident from the light source unit 1100 to the first incident module 1210a can be guided by the guide component 1220 to pass through the space located on the upper side with the optical axis Ax of the emitting unit 1221 as the reference and be focused at the rear focus F of the emitting unit 1221 or near it, and emitted through the emitting unit 1221.

[0125] That is, the light L1 incident on the first incident module 1210a can be focused at the rear focus F of the emitting portion 1221 or near it by adjusting the curvature or angle of the area located above the central surface 1211, the protruding surface 1212 and the reflecting surface 1213 with the optical axis Ax of the emitting portion 1221 as the reference.

[0126] Figure 15 and Figure 16 is a schematic diagram illustrating a path of light incident on a second incident module according to an embodiment of the present invention.

[0127] Reference Figure 15 and Figure 16 The light L2 that is incident from the light source unit 1100 to the second incident module 1210b and travels as parallel light approximately parallel to the optical axis Ax of the emitting unit 1221 is reflected laterally by the first reflecting surface 1222a. The light reflected laterally by the first reflecting surface 1222a is reflected upward by the second reflecting surface 1222b. The light reflected upward by the second reflecting surface 1222b can be guided to pass through the upper reflecting unit 1223 and be focused at the rear focus F of the emitting unit 1221 or near it, and be emitted through the emitting unit 1221.

[0128] at this time, Figure 15 This is an example of a case where the path of light reflected upward by the second reflective surface 1222b is omitted. Figure 16 This is an example of a case where the path of light reflected to the side by the first reflective surface 1222 a is omitted.

[0129] As described above, in the lamp module 1000 of the present invention, when a low beam pattern LP is formed that irradiates light downward based on the cut-off line CL, light blocked to form the cut-off line CL travels to the emission portion 1221 and is emitted as loss-free as possible, thereby reducing light loss and improving light efficiency.

[0130] In addition, in the above embodiment, the following situation is used as an example for explanation: the light incident on the first incident module 1210a is concentrated at the rear focus F of the emission portion 1221 or in the vicinity thereof, and the light incident on the second incident module 1210b is parallel light that is substantially parallel to the optical axis Ax of the emission portion 1221. Therefore, in order to keep the light incident on the second incident module 1210b parallel light, the first reflection surface 1222a and the second reflection surface 1222b have a planar shape, but the present invention is not limited thereto. In the case where the first incident module 1210a and the second incident module 1210b are formed symmetrically to each other due to process requirements, not only the light incident on the first incident module 1210a, but also the light incident on the second incident module 1210b travels in a manner of focusing on the rear focus F of the emission portion 1221 or in the vicinity thereof. Therefore, at least one of the first reflection surface 1222a and the second reflection surface 1222b can be formed to have a curved surface shape, so that the light incident on the second incident module 1210b is converted into parallel light.

[0131] That is, Figures 17 to 19 As shown, in the case where the first incident module 1210a and the second incident module 1210b of the incident portion 1210 have the same length d3, d4 and the same curvature R3, R4 in the up-down direction and the left-right direction, respectively, similar to the first incident module 1210a, since the light incident on the second incident module 1210b also travels in a manner of focusing at the rear focus F1 of the emission portion 1221 or in the vicinity thereof, at least one of the first reflection surface 1222a and the second reflection surface 1222b is formed to have a curved surface shape. In an embodiment of the present invention, the case where the first reflection surface 1222a has a curved surface shape and the second reflection surface 1222b is formed to have a flat surface shape, so that the light incident on the second incident module 1210b is converted into parallel light by the first reflection surface 1222a, is explained as an example.

[0132] In an embodiment of the present invention, as described above, at least one of the first reflecting surface 1222a and the second reflecting surface 1222b is made to have a curved surface shape, so that the light incident on the second incident module 1210b is converted into parallel light. This is because the upper reflecting portion 1223 has a curved surface shape, so that the light reflected by the upper reflecting portion 1223 is focused at the rear focus F of the emitting portion 1221 or near it, and thus the light traveling from the lower reflecting portion 1222 to the upper reflecting portion 1223 needs to travel as parallel light.

[0133] Figure 20 is a perspective view showing a lamp module according to another embodiment of the present invention, Figure 21 FIG. 4 is a schematic diagram illustrating a light path of a lamp module according to another embodiment of the present invention.

[0134] Reference Figure 20 and Figure 21 According to another embodiment of the present invention, the lamp module 1000 may include a transmissive portion 1222c that allows the lower reflective portion 1222 to transmit light together with the first reflective surface 1222a and the second reflective surface 1222b.

[0135] That is, in the above embodiment, the light incident on the second incident module 1210b is entirely reflected to the upper reflective portion 1223 by the lower reflective portion 1222. However, in another embodiment of the present invention, a portion of the light L3 incident on the second incident module 1210b passes through the transmissive portion 1222c and travels. The light L3 passing through the transmissive portion 1222c travels to the emitting portion 1221 through the connecting surface 1225 connecting the front end of the shielding portion 1224 and the lower surface of the guide member 1220. Figure 22 As shown, the lamp module 1000 of the present invention can simultaneously form a low beam pattern LP and an additional beam pattern AP.

[0136] In another embodiment of the present invention, the following situation is taken as an example for explanation: since the light L3 that travels to the emission portion 1221 through the transmission portion 1222c and the connecting surface 1225 passes through the lower space and travels to the emission portion 1221 based on the rear focus F of the emission portion 1221, it is refracted toward the relatively upper side when emitted through the emission portion 1221, thereby forming a signal beam pattern as an additional beam pattern AP that is easy to confirm road signs and the like located on the upper side based on the driver's line of sight, but is not limited to this. The light distribution characteristics of the additional beam pattern AP can be changed in various ways according to the formation angle of at least one of the transmission portion 1222c and the connecting surface 1225, etc.

[0137] As described above, since the lower side reflection portion 1222 includes the transmission portion 1222c, the optical system (i.e., the light source portion 1100 and the light guide portion 1200) for forming the low beam pattern LP and the additional beam pattern AP can be shared. Thus, since there is no need to separately equip optical systems for forming different beam patterns, the structure can be simplified and the cost can be reduced.

[0138] Figure 23 and Figure 24 is a perspective view showing a lamp module according to another embodiment of the present invention, Figure 25 FIG. 4 is a schematic diagram illustrating a light path of a lamp module according to another embodiment of the present invention.

[0139] Reference Figures 23 to 25 According to another embodiment of the present invention, the lamp module 1000 may form a recessed portion 1226 on the upper surface of the guide member 1220 and may form a shielding groove 1224 a behind the edge portion E of the shielding portion 1224 .

[0140] The recessed portion 1226 is used to make the light beam pattern formed by the lamp module 1000 of the present invention have a brightness distribution that satisfies the light distribution rule, such as Figure 26 As shown, among the light incident on the incident portion 1210 and traveling to the emission portion 1221, the path of the light L4 passing through a portion of the upper space with respect to the rear focus F of the emission portion 1221 is adjusted, so that the lower boundary line of the light distribution pattern P formed by the lamp module 1000 according to the present invention can be moved upward and set to prevent excessive formation of points having a brightness above the set brightness on the lower side.

[0141] At this time, since the light L4 whose path is adjusted by the recessed portion 1226 may become the cause of light loss, the angle or curvature formed by at least one of the rear surface 1226a and the front surface 1226b of the recessed portion 1226 is adjusted, so that the light L4 whose path is adjusted by the recessed portion 1226 is irradiated to the extended area described later and to the enhanced area P' of the lower area of ​​the enhanced low beam pattern LP, thereby improving light efficiency by reducing light loss and enhancing the field of view at a close distance in front of the vehicle.

[0142] For example, the lamp module 1000 of the present invention is composed of more than two lamp modules. When any one of the two or more lamp modules forms a light distribution pattern corresponding to a high illumination area and forms a recessed portion 1226, the light whose path is adjusted by the recessed portion 1226 can enhance close-range vision by strengthening the lower area of ​​the light distribution pattern corresponding to an extended area formed by another one of the two or more lamp modules.

[0143] In addition, if Figure 27 As shown, the shielding groove 1224a can prevent glare to the driver of the oncoming vehicle by recessing a portion of the cut-off line corresponding to the oncoming lane.

[0144] In another embodiment of the present invention, the case where the recessed portion 1226 and the shielding groove 1224a are formed together is described as an example, but this is only an example to help understand the present invention and is not limited to this. Any one of the recessed portion 1226 and the shielding groove 1224a can also be formed and the other can be omitted.

[0145] Figure 28 1 is a plan view showing a vehicle lamp according to an embodiment of the present invention.

[0146] Reference Figure 28 The vehicle lamp 1 according to the embodiment of the present invention may include a plurality of lamp units 100 arranged in the left-right direction.

[0147] at this time, Figure 28This is an example of a headlamp installed on the left side of both sides in front of the vehicle. It can be understood that the vehicle lamp 1 of the present invention and the installation direction or position can also be installed on the right side in front of the vehicle by appropriately changing the vehicle lamp 1 and the installation direction or position.

[0148] Each of the multiple lamp units 100 may include at least one lamp module 1000. In the embodiment of the present invention, the case where at least one lamp module 1000 of each of the multiple lamp units 100 is formed integrally with each other is taken as an example for explanation. In this case, it can be understood that the multiple lamp units 100 are formed integrally with each other.

[0149] Furthermore, in the embodiment of the present invention, the fact that at least one lamp module 1000 of each of the plurality of lamp units 100 is integrally formed with one another may be understood as the fact that the light guide portion 1200 of at least one lamp module 1000 is integrally formed with one another.

[0150] In the embodiment of the present invention, the case where each of the multiple lamp units 100 includes two lamp modules 1000 arranged in the left-right direction is used as an example for description, but the present invention is not limited to this. According to the light distribution characteristics of the beam pattern formed by the vehicle lamp 1 of the present invention, the number of lamp modules included in each of the multiple lamp units 100 can be changed in various ways.

[0151] At this time, at least one lamp module 1000 included in each of the plurality of lamp units 100 may be any one of the lamp modules of the above-described embodiments.

[0152] In the case where at least one of the multiple lamp units 100 includes a plurality of lamp modules 1000 arranged in the left-right direction, the guide part 1220 of each of the multiple lamp modules 1000 can be formed integrally and form an incident surface, and the incident portion 1210 of each of the multiple lamp modules 1000 can be spaced apart at predetermined intervals to prevent interference of light between each other.

[0153] The vehicle lamp 1 of the present invention includes a plurality of lamp units 100 . Since each of the plurality of lamp units 100 includes at least one lamp module 1000 , it can be understood that the vehicle lamp 1 of the present invention forms a beam pattern by means of the plurality of lamp modules 1000 .

[0154] The plurality of lamp units 100 may be formed with a step difference so as to be gradually located rearward from the inside toward the outside of the vehicle, similar to the emission portion 1221 of the lamp module 1000 described above, so that the plurality of lamp units 100 are arranged along the body line of the vehicle.

[0155] The plurality of lamp modules 1000 included in the above-mentioned vehicle lamp 1 can be divided into a plurality of groups G1, G2, and G3 of different areas for forming a low beam pattern LP. In an embodiment of the present invention, the following situation is taken as an example: the first group G1 consisting of five lamp modules along the left-right direction from the inside to the outside of the vehicle forms a first light distribution pattern P1 corresponding to a high illumination area with relatively high brightness to ensure a sufficiently long field of view distance. Then, the second group G2 consisting of four lamp modules forms a second light distribution pattern P2 corresponding to a wider middle area than the high illumination area. Then, the third group G3 consisting of three lamp modules forms a third light distribution pattern P3 corresponding to an extended area for ensuring a sufficiently wide field of view. In this case, the above-mentioned light distribution pattern P1, the second light distribution pattern P2, and the third light distribution pattern P3 can be synthesized to form the above-mentioned Figure 8 Low beam pattern LP.

[0156] The vehicle lamp 1 of the present invention is divided into three groups G1, G2, and G3 for the purpose of helping to understand the present invention. The present invention is not limited thereto. The vehicle lamp 1 of the present invention may be composed of at least one group according to the light distribution pattern required to form a beam pattern suitable for the purpose of the vehicle lamp 1 of the present invention.

[0157] At this time, the shapes of the plurality of emission surfaces 1221 a forming the emission portion 1221 of each of the plurality of lamp modules 1000 may vary according to the region in which each of the plurality of lamp modules 1000 is formed.

[0158] That is, as in the first group G1 and the second group G2, when the light-dark cutoff line CL is formed so that the first line CL1 is located on the upper side compared to the second line CL2, glare may be generated due to the light irradiated to the upper side of the second line CL2 having a relatively low height, and such glare can be generated by the side surface 1221a' between the adjacent emission surfaces among the multiple emission surfaces 1221a.

[0159] In other words, if Figure 29As shown, among the emission surfaces 1221a adjacent to each other in the left-right direction, the side surface 1221a' of the emission surface located in front can be formed to be inclined outward so that the rear end is located outward compared to the front end. This is because, when the light L5 emitted from the emission surface located in the rear among the emission surfaces adjacent to each other toward the side surface 1221a' is reflected in the opposite direction by the side surface 1221a', glare may be generated due to the illumination of the upper area WA of the second line CL2. Therefore, the side surface 1221a' of the emission surface located in front among the emission surfaces adjacent to each other in the left-right direction is formed to be inclined outward at a predetermined angle θ, so that the light emitted from the emission surface located in the rear among the emission surfaces adjacent to each other passes through the inside of the guide component 1220 and is emitted using the emission surface located in the front among the emission surfaces adjacent to each other to prevent glare.

[0160] That is, in a case where the front and rear ends of the side surface 1221a' located between the mutually adjacent emission surfaces 1221a are formed parallel to the front-to-back direction, light emitted from the emission surface located at the rear among the mutually adjacent emission surfaces is reflected in the opposite direction by the side surface 1221a' located between the mutually adjacent emission surfaces 1221a and generates glare, so that the rear end is formed inclined so as to be located outward compared to the front end of the side surface 1221a' located between the mutually adjacent emission surfaces 1221a.

[0161] In addition, the lamp modules belonging to the third group G3 may form the edge portion E as an edge without a step difference, which may be understood as the second line CL2 .

[0162] At this time, as the expansion area expands in the left and right directions, a wider field of view can be ensured, so Figure 30 As shown, the side surface 1221a' of the front exit surface among the adjacent exit surfaces may be formed to be inclined toward the inside so as to be gradually located inside the vehicle from the front end toward the rear end.

[0163] In other words, if Figure 30 As shown, the light L6 emitted from each of the multiple emission surfaces 1221a is further refracted and emitted toward the center of the emission surface the farther the light is emitted from a point that is farther away from the center of the emission surface in the left-right direction. Therefore, the side surface 1221a' of the front emission surface among the emission surfaces 1221a adjacent to each other in the left-right direction is formed to be inclined inwardly at a predetermined angle θ', so that the rear emission surface among the emission surfaces 1221a adjacent to each other in the left-right direction can be further expanded relatively in the left-right direction. Since the light emitted from the expanded part is further refracted and emitted toward the center of the emission surface, the expansion area is widened to increase the width of the beam pattern formed by the vehicle lamp 1 of the present invention.

[0164] At this time, Figure 30 In FIG. 1 , double-dashed arrows indicate light paths when the front and rear ends of the side surface 1221 a ′ of the front exit surface among the mutually adjacent exit surfaces 1221 a are formed parallel to the front-rear direction.

[0165] As described above, the vehicle lamp 1 of the present invention adjusts the shape of the emission portion 1221 of each of the multiple lamp modules 1000 (i.e., the curvature, formation angle, size, etc. of each of the multiple emission surfaces 1221a) according to the light distribution pattern formed by each of the multiple lamp modules 1000 to form an optimal beam pattern.

[0166] As described above, the lamp module of the present invention and the vehicle lamp including the lamp module can improve light efficiency by reducing light loss caused by blocked light when forming the cut-off line CL of the low beam pattern LP. Since the beam pattern is formed by multiple lamp modules arranged in the left and right directions, a slim appearance can be achieved and the optimal beam pattern can be formed by adjusting the shape of the multiple emission surfaces 1221a of the emission portion 1221.

[0167] It will be understood by those with ordinary knowledge in the technical field to which the present invention belongs that the present invention can be implemented in other specific forms without changing its technical ideas or essential features. Therefore, the embodiments described above should be understood to be illustrative in all aspects and not restrictive. The scope of the present invention is indicated by the scope of the claims, rather than the detailed description above, and should be interpreted as all changes or modifications derived from the meaning and scope of the claims and their equivalents are included in the scope of the present invention.
