Description

Technical Field

[0001] The present invention relates to a vehicle lamp, and more particularly to a vehicle lamp capable of forming an optimal beam pattern. Background Art

[0002] Generally, a vehicle has a plurality of lamps for the purpose of providing an illumination function for easily recognizing objects around the vehicle when traveling at night and a signal function for notifying surrounding vehicles or pedestrians of the vehicle's traveling state.

[0003] For example, headlights and fog lights are mainly intended for lighting, while turn signals, taillights and brake lights are mainly intended for signaling. The setting criteria and specifications of each lamp have been stipulated through laws and regulations so that their respective functions can be fully utilized.

[0004] Among them, the headlights irradiate light in the direction of travel of the vehicle to ensure the driver's forward field of vision, thereby playing a very important role in achieving safe driving.

[0005] The headlamp can form a low beam pattern that irradiates light downwardly with a cutoff line as a reference, or a high beam pattern that irradiates light at least partially above the cutoff line. When irradiating light above the cutoff line when forming the low beam pattern, it may cause dazzle to the driver of the vehicle ahead. Therefore, a solution is needed to prevent light from being irradiated above the cutoff line when forming the low beam pattern.

[0006] [Prior art literature] [Patent Literature] Patent Document 1: Korean Patent Publication No. 10-2023-0056465 (published on April 27, 2023) Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a vehicle lamp that can form an optimal beam pattern by preventing light from being emitted in unnecessary directions.

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

[0009] In order to achieve the above technical problem, a vehicle lamp according to an embodiment of the present invention forms a predetermined beam pattern by means of at least one lamp module, wherein the at least one lamp module may include: a light source portion, including at least one light source; and an optical portion, allowing at least a portion of the light emitted from the light source portion to be transmitted to form the beam pattern, wherein the optical portion includes: an incident portion, including a plurality of incident lenses; and an emission portion, including a plurality of emission lenses corresponding to the plurality of incident lenses, wherein each of the plurality of emission lenses is formed to have a length in the up-and-down direction that is longer than a length in the left-and-right direction.

[0010] The optical portion may be arranged to be inclined in such a manner that the other side is located forward of the one side in at least one direction.

[0011] The plurality of emission lenses may be formed such that a length in a vertical direction is longer than a length in a horizontal direction.

[0012] Each of the plurality of incident lenses may correspond to two or more of the plurality of exit lenses, and each of the two or more exit lenses may be formed to have a length in a vertical direction longer than a length in a left-right direction.

[0013] The plurality of incident lenses and the plurality of emission lenses may correspond to each other one-to-one, and the corresponding incident lenses and emission lenses among the plurality of incident lenses and the plurality of emission lenses may be formed to have a length longer in a vertical direction than in a left-right direction.

[0014] The vehicle lamp may further include a plurality of shielding members that block a portion of the light traveling toward each of the plurality of emission lenses.

[0015] Each of the plurality of shielding members may be located at a focal point formed between corresponding input lenses and output lenses among the plurality of input lenses and the plurality of output lenses, and based on the focal point, a focal length of the corresponding input lens may be longer than a focal length of the corresponding output lens.

[0016] In each of the plurality of shielding members, a first surface facing the plurality of incident lenses and a second surface facing the plurality of exit lenses may have reflectivities different from each other.

[0017] The second surface may have a higher reflectivity than the first surface.

[0018] The vehicle lamp may further include: an optical path conversion unit for converting a path of light so that the light emitted from the light source unit is converted into parallel light and travels to the optical unit.

[0019] The ratio of the length in the left-right direction to the length in the up-down direction may be 1:1.2 to 1:2.0.

[0020] Details of other embodiments are included in the detailed description and drawings.

[0021] According to the vehicle lamp of the present invention as described above, one or more of the following effects are achieved.

Throughout the specification, the same figure numerals refer to the same components.

[0041] Hereinafter, the present invention will be described based on the embodiments of the present invention by referring to the accompanying drawings for describing a vehicle lamp.

[0042] Figure 1 is a perspective view showing a vehicle lamp according to an embodiment of the present invention, Figure 2 is a side view showing a vehicle lamp according to an embodiment of the present invention, Figure 3 1 is a plan view showing a vehicle lamp according to an embodiment of the present invention.

[0043] Reference Figures 1 to 3 According to an embodiment of the present invention, the vehicle lamp 1 may include a plurality of lamp modules 1000 arranged in one direction. In the following, in the embodiment of the present invention, the following situation is taken as an example for explanation: the X-axis direction is the left-right direction, indicating the vehicle width direction, the Y-axis direction is the front-back direction, indicating the driving direction, and the Z-axis is the up-down direction, indicating the vehicle height direction.

[0044] In an embodiment of the present invention, the vehicle lamp 1 is explained by taking the following situation as an example: when the vehicle is driving at night or in a dark place such as a tunnel, the headlamp is used to irradiate light in the driving direction of the vehicle to ensure the front field of vision of the vehicle, but it is not limited to this. The vehicle lamp 1 according to the present invention can be used not only as a headlamp, but also as various lamps arranged in the vehicle such as fog lights, daytime running lights, turn signal lights, tail lights, backup lights, brake lights, etc., and the vehicle lamp 1 of the present invention can be used as one of the above-mentioned various lamps, or can be used as two or more at the same time.

[0045] When the vehicle lamp 1 of the present invention is used as a headlamp, at least one of a low beam pattern and a high beam pattern can be formed. The low beam pattern irradiates light to the lower side based on a cutoff line of a predetermined shape, thereby preventing dazzle to the driver of a front vehicle such as a preceding vehicle or an oncoming vehicle, and ensuring a wide field of view at a short distance in front of the vehicle. The high beam pattern irradiates at least a portion of the light to the upper side based on the cutoff line, thereby ensuring a long field of view at a long distance in front of the vehicle. In the following, in an embodiment of the present invention, as Figure 4As shown, a case where a low beam pattern P having a predetermined cutoff line CL is formed by the vehicle lamp 1 is described as an example.

[0046] In addition, in an embodiment of the present invention, a case where a vehicle lamp 1 includes a plurality of lamp modules 1000 arranged in an up-and-down direction 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. Various changes may be made according to the light distribution characteristics of a light beam pattern formed by the vehicle lamp 1 of the present invention (i.e., the position, size, shape, brightness, etc. of the light irradiation area), including the number and arrangement direction of the lamp modules in the vehicle lamp 1 of the present invention.

[0047] At this time, a case where a plurality of lamp modules 1000 are arranged in the up-down direction and the lamp modules are gradually located in front from the upper side toward the lower side and are located on the right side is described as an example, but this is only an example to help understand the present invention and is not limited to this. According to the layout or design reasons of the vehicle lamp 1 of the present invention, the plurality of lamp modules 1000 can be arranged to be staggered from one side to the other in at least one direction so that adjacent lamp modules are staggered from each other along one direction.

[0048] The beam pattern formed by the vehicle lamp 1 according to the present invention may be formed by overlapping or synthesizing sub-beam patterns formed by each of the plurality of lamp modules 1000 .

[0049] For example, the beam pattern formed by the vehicle lamp 1 according to the present invention can be formed by overlapping or synthesizing sub-beam patterns having the same light distribution characteristics formed by each of a plurality of lamp modules 1000, or can be formed by synthesizing sub-beam patterns having different light distribution characteristics formed by each of a plurality of lamp modules 1000.

[0050] Figure 5 and Figure 6 is a perspective view showing a lamp module according to an embodiment of the present invention, Figure 7 is a side view showing a lamp module according to an embodiment of the present invention, Figure 8 is a plan view showing a lamp module according to an embodiment of the present invention, Figures 5 to 8 1000 is an example showing a case where one of the plurality of lamp modules 1000 is shown, and other lamp modules may be similarly applied.

[0051] Reference Figures 5 to 8 , the lamp module 1000 according to the embodiment of the present invention may include a light source part 1100 , a light path conversion part 1200 and an optical part 1300 .

[0052] The light source part 1100 may include at least one light source that generates light of a light quantity or a color suitable for the purpose of the lamp module 1000 of the present invention.

[0053] In the embodiments of the present invention, the case of using a semiconductor light-emitting element such as a light emitting diode (LED) as at least one light source is described as an example, but the present invention is not limited to this. 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, and optical elements such as a reflector, a mirror, a prism, a phosphor, etc. can be additionally used depending on the type of the light source.

[0054] The optical path conversion unit 1200 can convert the light emitted from the light source unit 1100 to a predetermined light irradiation range into parallel light, whereby the light emitted from the light source unit 1100 is uniformly incident on the optical unit 1300 located in front of the optical path conversion unit 1200, so that the light beam pattern formed by the vehicle lamp 1 according to the present invention can have an overall uniform brightness.

[0055] That is, the light source unit 1100 can emit light in a predetermined angle range based on the optical axis Ax which is the axis passing through the center of the light-emitting area, and the optical path conversion unit 1200 can convert the path of light so that the light emitted from the light source unit 1100 is emitted approximately parallel to the optical axis Ax.

[0056] In an embodiment of the present invention, the case of using an aspheric lens as the optical path conversion unit 1200 is described as an example, but it is not limited to this. The optical path conversion unit 1200 can not only use an aspheric lens, but also can use various types of lenses such as a Fresnel lens or a total internal reflection (TIR: Total Internal Reflection) lens that converts the light incident from the light source unit 1100 into parallel light.

[0057] The optical portion 1300 can transmit at least a portion of the light emitted from the optical path conversion portion 1200 , thereby playing a role in forming a beam pattern suitable for the vehicle lamp 1 according to the present invention.

[0058] Fig. 9 and Fig.10 is an exploded perspective view showing an optical portion according to an embodiment of the present invention.

[0059] Reference Fig. 9 and Fig.10 According to an embodiment of the present invention, the optical portion 1300 may include an incident portion 1310 and an emitting portion 1320 .

[0060] The incident portion 1310 may include a plurality of incident lenses 1311 and a first light transmitting portion 1312 , and the emission portion 1320 may include a plurality of emission lenses 1321 and a second light transmitting portion 1322 .

[0061] A plurality of incident lenses 1311 may be arranged on the incident surface 1312a of the first light transmission portion 1312, a plurality of exit lenses 1321 may be arranged on the exit surface 1322b of the second light transmission portion 1322, and the exit surface 1312b of the first light transmission portion 1312 and the incident surface 1322a of the second light transmission portion 1322 may be connected or adjacently arranged in a manner opposite to each other, so that light incident on the plurality of incident lenses 1311 may travel to the plurality of exit lenses 1321 through the first light transmission portion 1312 and the second light transmission portion 1322.

[0062] At this time, in order to reduce the size of the vehicle lamp 1 of the present invention, a case where micro lenses having a relatively short focal length are used as the plurality of incident lenses 1311 and the plurality of emission lenses 1321 will be described as an example.

[0063] In an embodiment of the present invention, the following situation is taken as an example for explanation: each of the multiple incident lenses 1311 is formed to extend in the left-right direction, and the light incident on each of the multiple incident lenses 1311 is emitted through more than two adjacent emission lenses in the left-right direction among the multiple emission lenses 1321, but this is to improve the expansion characteristics of the sub-beam pattern formed by the lamp module 1000 of the present invention, and is not limited to this, and the multiple incident lenses 1311 and the multiple emission lenses 1321 can also correspond one-to-one.

[0064] The first light-transmitting portion 1312 may be formed to have a thickness corresponding to the focal length of the plurality of incident lenses 1311, and the second light-transmitting portion 1322 may be formed to have a thickness corresponding to the focal length of the plurality of exit lenses 1321, and in a case where the first light-transmitting portion 1312 and the second light-transmitting portion 1322 are disposed in contact with each other, a focal point formed between the incident lenses and the exit lenses corresponding to each other among the plurality of incident lenses 1311 and the plurality of exit lenses 1321 may be provided at an interface between the first light-transmitting portion 1312 and the second light-transmitting portion 1322.

[0065] At this time, the focal point may have a shape of a point, a line, a surface, a space, or a combination thereof according to the shape of a region where light is substantially concentrated.

[0066] Fig.11 Schematic diagram showing focal lengths of an incident lens and an exit lens according to an embodiment of the present invention.

[0067] Reference Fig.11In an embodiment of the present invention, the first focal length f1 (i.e., the distance from the first incident lens 1311a to the focal point F among the multiple incident lenses 1311) can be formed to be longer than the second focal length f2 (i.e., the distance from the first output lens 1321a corresponding to the first incident lens 1311a to the focal point F among the multiple output lenses 1321). This is to prevent the light from being incident on other output lenses adjacent to the first output lens 1321a in addition to the first output lens 1321a when the light incident on the first incident lens 1311a is focused on the focal point F and incident on the first output lens 1321a.

[0068] In other words, as the second focal length f2 becomes longer, in order to allow the light incident on the first incident lens 1311a to be incident on the first output lens 1321a without loss, the size of the first output lens 1321a needs to be increased. Therefore, the second focal length f2 is shorter than the first focal length f1, thereby preventing the size of the first output lens 1321a from increasing.

[0069] In addition, in an embodiment of the present invention, Fig.12 As shown, the multiple emission lenses 1321 can be formed so that the length d2 in the up and down direction is longer than the length d1 in the left and right direction. This is to prevent the following situation: the light incident on each of the multiple incident lenses 1311 is incident on other adjacent emission lenses in addition to the corresponding emission lens in the multiple emission lenses 1321, so that the light is emitted in unnecessary directions. A detailed explanation of this will be described later.

[0070] A plurality of shielding members 1330 may be provided between the corresponding incident lenses and the exit lenses among the plurality of incident lenses 1311 and the plurality of exit lenses 1321, and the upper end of each of the plurality of shielding members 1330 may be located at or near the rear focus of each of the plurality of exit lenses 1321 (i.e., formed at the focus of the corresponding incident lenses and the exit lenses), so that a low beam pattern having a cutoff line of a predetermined shape is formed as a sub-beam pattern by means of the lamp module 1000 of the present invention.

[0071] That is, with the rear focus of each of the multiple emission lenses 1321 as a reference, the light that travels through the lower space and is emitted is emitted in a manner of being refracted relatively toward the upper side. As a result, the light is irradiated to the upper side of the cut-off line and glare may be generated. Therefore, multiple shielding members 1330 are used to block the light that travels through the lower space with the rear focus of each of the multiple emission lenses 1321 as a reference.

[0072] At this time, the length d2 of the multiple emission lenses 1321 in the up and down direction is made longer than the length d1 in the left and right direction to prevent the following situation: the light traveling through each of the multiple shielding members 1330 is incident on other adjacent emission lenses in addition to the corresponding emission lens in the multiple emission lenses 1321, so that the light is emitted in unnecessary directions.

[0073] That is, in order to shorten the second focal length f2, it is necessary to make the curvature of the multiple emission lenses 1321 larger, so that the size along the front-to-back direction increases. The shorter the second focal length f2 is, the smaller the area from which light is actually emitted from each of the multiple emission lenses 1321. The image formed by the light emitted from the lamp module 1000 of the present invention may have an overall uneven brightness, thereby limiting the shortening of the second focal length f2.

[0074] Therefore, in an embodiment of the present invention, the plurality of emission lenses 1321 are formed such that the length d2 in the up-down direction is longer than the length d1 in the left-right direction, so that the plurality of emission lenses 1321 have an appropriate size and have a second focal length f2 that makes the image formed by the light emitted from the lamp module 1000 of the present invention have an overall uniform brightness, and prevents light passing through each of the plurality of shielding members 1330 and traveling in parallel from being incident on other emission lenses adjacent to the corresponding emission lenses among the plurality of emission lenses 1321.

[0075] In other words, the multiple emission lenses 1321 are usually formed with a ratio of 1:1 between the length d1 in the left-right direction and the length d2 in the up-down direction, but in an embodiment of the present invention, the ratio of the length d1 in the left-right direction and the length d2 in the up-down direction can be formed to be 1:m (m>1), and m can have a value between 1.2 and 2.0. When m is less than 1.2, light incident on each of the multiple incident lenses 1311 is likely to be emitted to other adjacent emission lenses in addition to the corresponding emission lens in the multiple emission lenses 1321. When m is greater than 2.0, the multiple emission lenses 1321 become too long in the up-down direction, making it difficult to meet the required light distribution characteristics.

[0076] At this time, in an embodiment of the present invention, a case where multiple incident lenses 1311 and multiple emission lenses 1321 correspond to each other in a one-to-many manner is used as an example for explanation, but it is not limited to this. When multiple incident lenses 1311 and multiple emission lenses 1321 correspond to each other one-to-one, the multiple incident lenses 1311 can also be formed in the same way as the multiple emission lenses 1321, with the ratio of the length d1 in the left-right direction to the length d2 in the up-down direction being 1:m (m>1).

[0077] Fig.13is a schematic diagram showing light paths corresponding to the shapes of a plurality of incident lenses and a plurality of exit lenses according to an embodiment of the present invention.

[0078] Reference Fig.13 Even when the first focal length f1 of the plurality of incident lenses 1311 is longer than the second focal length f2 of the plurality of emission lenses 1321, the ratio of the length d1 in the left-right direction to the length d2 in the up-down direction of the plurality of incident lenses 1311 and the plurality of emission lenses 1321 is 1: In the case of 1 (i.e., the length d1 of the plurality of emission lenses 1321 in the left-right direction is the same as the length d2 in the up-down direction, so that d1=d2), among the light L1 and L2 passing through the plurality of shielding members 1330, a part of the light L1 may be emitted through the corresponding emission lens of the plurality of emission lenses 1321, while another part of the light L2 may be emitted through other adjacent emission lenses and irradiated to unnecessary directions, thereby possibly generating glare, and therefore it may be necessary to form an additional shielding member 1340 in front of the plurality of shielding members 1330 for preventing glare. In an embodiment of the present invention, the plurality of incident lenses 1311 and the plurality of emission lenses 1321 are formed such that the length d2 in the up-down direction is longer than the length d1 in the left-right direction, and therefore, without forming the additional shielding member 1340, the light passing through the plurality of shielding members 1330 may be prevented from being emitted through other emission lenses adjacent to the corresponding emission lens of the plurality of emission lenses 1321, thereby preventing glare.

[0079] At this time, Fig.13 In the figure, when d1=d2, the light L2 represented by the dotted arrow represents the light path when the ratio of the length d1 in the left-right direction of the multiple incident lenses 1311 and the length d2 in the up-down direction of the multiple incident lenses 1311 and the multiple emission lenses 1321 is 1:1 and the additional shielding member 1340 is not formed, and it can be seen that the light incident on each of the multiple incident lenses 1311 travels to other emission lenses adjacent to the corresponding emission lens in the multiple emission lenses 1321, thereby being refracted in the upward or downward direction and irradiated in unnecessary directions.

[0080] In addition, in an embodiment of the present invention, Fig.14 As shown, the plurality of shielding members 1330 may include a first surface 1331 facing the plurality of incident lenses 1311 and a second surface 1332 facing the plurality of exit lenses 1321 , and the first surface 1331 and the second surface 1332 may have different reflectivities (absorption rates) from each other.

[0081] In an embodiment of the present invention, the second surface 1332 may have a higher reflectivity than the first surface 1331. To this end, each of the plurality of shielding members 1330 may be formed by depositing a first reflective layer 1330a for forming the first surface 1331 and a second reflective layer 1330b for forming the second surface 1332. The number of deposition layers constituting each reflective layer 1330a, 1330b, the materials of the deposition layers, the deposition order of the deposition layers, etc. may be different from each other according to the reflectivity of each reflective layer 1330a, 1330b.

[0082] At this time, the reason why the first surface 1331 can have a lower reflectivity than the second surface 1332 is that, when light incident to each of the multiple incident lenses 1311 is reflected by the first surface 1331 of each of the multiple shielding members 1330, it is difficult to control the path of the light, and thus the amount of light incident to each of the multiple incident lenses 1311 that is reflected by the multiple shielding members 1330 can be reduced.

[0083] Furthermore, the second surface 1332 is a surface that can be observed when observing from the outside of the vehicle, and can form an image based on external light such as sunlight incident on the optical portion 1300 during the day and reflected forward by the second surface 1332, thereby achieving an aesthetic appearance not only at night but also during the day.

[0084] In other words, a decrease in the reflectivity of the second surface 1332 can be regarded as an increase in the absorptivity. As the absorptivity of the second surface 1332 increases, the second surface 1332 is displayed in a darker color or black, and thus the aesthetic sense may be reduced when viewed from the outside. On the contrary, in an embodiment of the present invention, the second surface 1332 is made to have a higher reflectivity than the first surface 1331, so that it appears white or silver when viewed from the outside, thereby improving the aesthetic sense.

[0085] In an embodiment of the present invention, the case where the first surface 1331 has a reflectivity of less than about 5% and the second surface 1332 has a reflectivity of more than about 90% 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. The first surface 1331 may have a reflectivity that does not change the light distribution characteristics of the light beam pattern due to light reflected by multiple shielding members 1330, and the second surface 1332 may have a reflectivity that enables an image formed by light reflected by multiple shielding members 1330 to have a desired color.

[0086] The optical portion 1300 described above may be provided obliquely in such a manner that the other side is located forward of the one side in at least one direction, and this is to arrange the optical portion 1300 along the body line of the vehicle.

[0087] That is, the lamp module 1000 of the present invention can be accommodated in a space formed by a lamp housing (not shown) and a cover lens (not shown) combined with the lamp housing, and the optical part 1300 is arranged according to the shape of the outer side surface of the cover lens forming a part of the body line of the vehicle. This can be understood as preventing the light emitted from the optical part 1300 from being interfered by the body around the cover lens.

[0088] As described above, in the vehicle lamp 1 of the present invention, the length of each of the multiple emission lenses 1321 in the up and down direction is made longer than the length in the left and right direction, so that light can be prevented from being emitted in unnecessary directions without forming an additional shielding member 1340, thereby reducing manufacturing costs and manufacturing processes.
