[0001] This utility model relates to a vehicle lighting fixture, and more specifically, to a vehicle lighting fixture that can enhance the aesthetic appeal of a lit image through a sense of three-dimensionality and a gem-like quality. Background Technology

[0002] Typically, vehicles have a variety of lights that enable easy identification of objects around the vehicle when driving at night, as well as signals that inform surrounding vehicles or pedestrians of the vehicle's driving status.

[0003] For example, headlights and fog lights are mainly intended for illumination, while turn signals, taillights, and brake lights are mainly intended for signaling. The setting standards and specifications for each type of light have been stipulated by regulations in order to fully realize their respective functions.

[0004] Recently, in addition to the basic function of vehicle lights in ensuring driver visibility and aiding safe driving, the aesthetic aspect of improved exterior design has also greatly influenced consumers' purchasing decisions. Therefore, diversifying the visually representable images through vehicle lights is becoming a trend.

[0006] The technical problem to be solved by this utility model is to provide a vehicle lamp that improves aesthetics by forming a illuminated image with a sense of three-dimensionality and depth.

[0007] Furthermore, a vehicle lamp is provided that can reduce the number of light sources required to form a lit image while reducing the overall size.

[0008] The technical problems of this utility model are not limited to those mentioned above. Those skilled in the art can clearly understand other technical problems not mentioned from the following description.

[0009] To address the aforementioned technical problems, the vehicle lamp according to an embodiment of the present invention is a vehicle lamp comprising at least one lamp module. The at least one lamp module may include a first lamp module, wherein the first lamp module may include: a light source portion comprising a plurality of light sources disposed on a substrate; a first lens portion having a reflective layer formed in a portion of an exit surface from which light emitted and incident from the light source portion exits, and a transmissive region for transmitting light formed in another portion of the exit surface; and a second lens portion having a semi-reflective layer formed in an incident surface from which light emitted from the first lens portion enters, wherein the first lens portion has a diffusion unit for diffusing light formed in at least a portion of the incident surface from which light emitted from the light source portion enters, wherein the plurality of light sources may include: a first light source disposed at a first density in a first region of the substrate; and a second light source disposed at a second density different from the first density in a second region of the substrate.

[0010] Light incident on the first lens portion can pass through the transmission region and proceed in parallel to the second lens portion. A portion of the light passing through the transmission region can pass through the semi-reflective layer to form an original image with a shape corresponding to the transmission region, and another portion of the light can be reflected by the semi-reflective layer and repeatedly reflected between the reflective layer and the semi-reflective layer to form at least one reflected image corresponding to the original image.

[0011] The diffusion unit may include: a first diffusion unit, which is formed in the incident surface of the first lens portion in a first pattern region corresponding to the first region; and a second diffusion unit, which is formed in the incident surface of the first lens portion in a second pattern region corresponding to the second region.

[0012] The first diffusion unit and the second diffusion unit may have different degrees of diffusion.

[0013] The first diffusion unit and the second diffusion unit can be formed at different densities.

[0014] One of the first diffusion unit and the second diffusion unit may be formed as a frustum-shaped cone with a planar central portion and a diameter that gradually increases from the edge of the central portion toward the rear, and the other may be formed as a spherical shape.

[0015] The first density can be higher than the second density, and the second diffusion unit can have a higher degree of diffusion compared to the first diffusion unit.

[0016] Compared to the second diffusion unit, the first diffusion unit can preserve more of the light's path in the light incident from the light source.

[0017] The first lighting module may include a first lighting area corresponding to the first region and a second lighting area corresponding to the second region, and the areas corresponding to the first lighting area and the areas corresponding to the second lighting area in the lighting image formed by the first lighting module may have different brightness levels.

[0018] The first lighting module can be installed on the ceiling of the vehicle interior, and the first illuminated area can be located at a set distance in front of the headrest of the vehicle seat.

[0019] The at least one lighting module may further include: a second lighting module disposed adjacent to the first lighting module, wherein the region with higher density in the first region and the second region may be located closer to the second lighting module.

[0020] To address the aforementioned technical problem, a vehicle lamp according to another embodiment of the present invention may include: a light source portion comprising a plurality of light sources disposed on a substrate; a first lens portion having a reflective layer formed in a portion of an exit surface from which light emitted from and incident upon the light source portion exits, and a transmissive region for transmitting light formed in another portion of the exit surface; and a second lens portion having a semi-reflective layer formed in an incident surface from which light emitted from the first lens portion enters, wherein the first lens portion has a diffusion unit for diffusing light formed in at least a portion of the incident surface from which light emitted from the light source portion enters, wherein the diffusion unit may include a first diffusion unit formed in a portion of the incident surface of the first lens portion and a second diffusion unit formed in another portion of the incident surface, wherein the first diffusion unit may be formed having a density different from that of the second diffusion unit.

[0021] Other specific details of this invention are included in the detailed description and accompanying drawings.

[0022] The vehicle lamp of this utility model, as described above, has one or more of the following effects.

[0023] Because light is repeatedly reflected between the first lens section and the second lens section, forming the original image and the reflected image of the original image, a illuminated image with a sense of three-dimensionality and depth can be formed, thereby enhancing the aesthetic appeal.

[0024] Furthermore, since a diffusion unit is formed in the first lens section that allows light emitted from the light source section to enter, the number of light sources used to form a lit image is reduced. Therefore, it also has the effect of reducing the number of parts to lower costs and reducing the distance between the light source section and the first lens section to reduce the overall size.

[0025] Furthermore, since the gradient effect can be achieved by adjusting the number of at least one of the light source and diffusion unit, it also has the ability to achieve a wider variety of image lighting effects.

[0026] The effects of this utility model are not limited to those mentioned above. Those skilled in the art can clearly understand other technical effects not mentioned by referring to the claims. Attached Figure Description

Moreover, in the various figures illustrated in this utility model, the constituent elements may be shown at varying degrees of enlargement or reduction for ease of explanation. Throughout this specification, the same reference numerals refer to the same constituent elements.

[0050] Hereinafter, the present invention will be described with reference to the accompanying drawings used to describe vehicle lighting fixtures, based on embodiments of the present invention.

[0051] Figure 1 This is a perspective view showing a vehicle lamp according to an embodiment of the present invention. Figure 2 It is along Figure 1 A cross-sectional view taken from the A-A' line.

[0052] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, the vehicle lamp 1 may include at least one lamp module 1000, and will be described with the X-axis representing the front-to-back direction, the Y-axis representing the left-to-right direction, and the Z-axis representing the up-to-down direction as an example.

[0053] At this time, the front-back direction is an example of assuming that the direction of the light irradiated from the vehicle lamp 1 of this utility model is forward, and the actual directions represented by the X-axis, Y-axis and Z-axis can be changed depending on the position or direction of the vehicle lamp 1 of this utility model.

[0054] In the embodiments of this utility model, the vehicle lamp 1 will be used as an example to inform surrounding vehicles or pedestrians of the vehicle's driving status, such as taillights, brake lights, and turn signals. However, it is not limited to this. The vehicle lamp 1 of this utility model can not only be used for lighting functions such as headlights and fog lights and signal functions such as taillights, brake lights, and turn signals, but also for various lamps installed on the vehicle for decorative lighting inside the vehicle or external lighting outside the vehicle.

[0055] Furthermore, in the embodiments of this utility model, the case of a vehicle lamp 1 including a single lamp module 1000 is used as an example for description, but it is not limited thereto. The vehicle lamp 1 of this utility model may also include two or more lamp modules arranged in at least one direction. In the case of the vehicle lamp 1 of this utility model including two or more lamp modules, each lamp module may be used for the same purpose or for different purposes.

[0056] At least one lighting module 1000 may include a light source section 1100, a first lens section 1200, and a second lens section 1300.

[0057] The light source unit 1100 can emit light with a light quantity or color suitable for the purpose of the vehicle lamp 1 of this utility model.

[0058] Figure 3 This is a front view showing the light source section according to an embodiment of the present invention.

[0059] Reference Figure 3 According to an embodiment of the present invention, the light source unit 1100 may include a plurality of light sources 1110 and a substrate 1120 provided with the plurality of light sources 1110.

[0060] In the embodiments of this utility model, the example of using a semiconductor light-emitting element such as a light-emitting diode (LED) as a plurality of light sources 1110 will be described, but it is not limited thereto. The plurality of light sources 1110 can not only use LEDs, but also various types of light sources such as laser diodes (LDs) or bulbs. Furthermore, depending on the type of light source, optical elements such as reflectors, phosphors, prisms, and mirrors can be added to adjust the path, color, brightness, etc. of the light.

[0061] The substrate 1120 can be configured to make thermal contact with a heat sink (not shown) to quickly release the high-temperature heat generated when light is emitted from the multiple light sources 1110, because the light-emitting performance of the multiple light sources 1110 will decrease sharply when the temperature rises due to the high-temperature heat.

[0062] The multiple light sources 1110 can be divided into multiple first light sources 1111 and multiple second light sources 1112, which belong to the first region 1121 and the second region 1122 of the substrate 1120, respectively.

[0063] Multiple first light sources 1111 can be configured to have a first density, and multiple second light sources 1112 can be configured to have a second density that is different from the first density. In the following embodiments of the present invention, the case in which multiple first light sources 1111 are configured to have a higher density than multiple second light sources 1112 is used as an example for explanation, and the arrangement density of light sources can be defined by the number of light sources per unit area.

[0064] In embodiments of this invention, a plurality of first light sources 1111 and a plurality of second light sources 1112 are configured to have different densities from each other in order to make a portion of the illuminated image formed by the vehicle lamp 1 of this invention have a brightness different from that of another portion of the image, as will be described in detail later.

[0065] In addition, in the embodiments of this utility model, the case in which the substrate 1120 includes a single first region 1121 and a single second region 1122 is used as an example for description, but this is only an example to help understand the utility model and is not limited thereto. At least one of the first region 1121 and the second region 1122 can be configured as more than two. In this case, the first region 1121 and the second region 1122 can be alternately arranged.

[0066] Furthermore, in embodiments of this invention, an example will be provided where the first region 1121 and the second region 1122 have the same shape. However, this is merely an example to aid in understanding the invention. Based on the brightness distribution of the illuminated image formed by the vehicle lamp 1 of this invention, such as... Figure 4 and Figure 5 As shown, the shape, position, and quantity of each of the first region 1121 and the second region 1122 can be varied.

[0067] The first lens portion 1200 can be disposed in front of the light source portion 1100 so that light emitted from the light source portion 1100 is incident in front.

[0068] In the embodiments of this utility model, the first lens portion 1200 is disposed in front of the light source portion 1100 as an example assuming that the direction of light irradiated from the vehicle lamp 1 of this utility model is forward. Depending on the position or direction of the vehicle lamp 1 of this utility model, the actual direction represented by forward can be changed.

[0069] Figure 6 and Figure 7This is a perspective view showing the first lens portion according to an embodiment of the present invention.

[0070] Reference Figure 6 and Figure 7 According to an embodiment of the present invention, the first lens portion 1200 may include an incident surface 1210 into which light emitted from the light source portion 1100 is incident and an exit surface 1220 into which at least a portion of the light incident on the incident surface 1210 is emitted.

[0071] The first lens portion 1200 can be formed such that at least a portion of the incident surface 1210 has a forward-recessed shape for the diffusion unit 1230. This diffusion unit 1230 can diffuse at least a portion of the light incident from the light source portion 1100, thereby reducing the number of light sources required for the vehicle lamp 1 of this invention while reducing the overall size.

[0072] That is, in order to emit light uniformly from the first lens section 1200 as a whole, it is necessary to make the light emitted from each of the plurality of light sources 1110 mix with each other sufficiently, and due to the light illumination angle of each of the plurality of light sources 1110, it is inevitably limited in terms of increasing the spacing between adjacent light sources among the plurality of light sources 1110.

[0073] In embodiments of this invention, by forming a diffusion unit 1230 on the incident surface 1210 of the first lens portion 1200, the number of light sources required to uniformly emit light from the first lens portion 1200 as a whole can be reduced while the overall size is reduced.

[0074] In the following embodiments of the present invention, an example will be given of using at least one of the first diffusion unit 1231 and the second diffusion unit 1232 as the diffusion unit 1230. However, this is only an example to help understand the present invention and is not limited thereto. The shape of the diffusion unit 1230 can be varied according to the required degree of diffusion (diffusion rate, diffusion angle, etc.).

[0075] Figure 8 This is a schematic diagram illustrating a first diffusion unit according to an embodiment of the present invention.

[0076] Reference Figure 8 According to an embodiment of the present invention, the first diffusion unit 1231 may include a central portion 1231a with a planar shape facing forward and a side portion 1231b formed to extend rearward from the edge of the central portion 1231a. The side portion 1231b may be formed to gradually increase in diameter towards the rear, thereby forming the side portion 1231b to have an overall frustum shape.

[0077] At this time, the central part 1231a has a planar shape, so the travel path of the light R11 incident from the light source part 1100 can remain unchanged, and the side part 1231b can diffuse the light R12 incident from the light source part 1100 at a predetermined diffusion angle.

[0078] In the embodiments of this utility model, the reason why the first diffusion unit 1231 includes a planar central portion 1231a is that even if the number of light sources is sufficient and the light path is maintained, the light can achieve a sparkling gem-like feeling when the first lens portion 1200 as a whole can emit light, and the light path is maintained by the central portion 1231a.

[0079] Figure 9 This is a schematic diagram illustrating a second diffusion unit according to an embodiment of the present invention.

[0080] Reference Figure 9 According to an embodiment of the present invention, the second diffusion unit 1232 can be formed as a curved surface to have a spherical shape, and the second diffusion unit 1232 can diffuse the light R2 incident from the light source 1100 in a manner having a different degree of diffusion than the first diffusion unit 1231.

[0081] At this time, the difference in the diffusion degree of the first diffusion unit 1231 and the second diffusion unit 1232 can be understood as at least one of the following being different: the amount of light maintained along the travel path, the amount of light diffused, and the diffusion angle.

[0082] In the embodiments of this utility model, unlike the first diffusion unit 1231 described above, the second diffusion unit 1232 does not form a planar central portion 1231a. Therefore, relatively less light remains on the path in the light incident from the light source portion 1100. Instead, more light is diffused. Even with a relatively small number of light sources, a high degree of diffusion can be achieved so that the first lens portion 1200 emits light as a whole. A high degree of diffusion can be understood as a relatively small amount of light remaining on the path.

[0083] The diffusion unit 1230 is not limited to the first diffusion unit 1231 and the second diffusion unit 1232 described above. Depending on the required diffusion level of the vehicle lamp 1 of this utility model, it can be formed into a shape having a plane, a curved surface, or a combination thereof.

[0084] Furthermore, in the embodiments of this utility model, the first diffusion unit 1231 and the second diffusion unit 1232 are collectively referred to as two diffusion units with different degrees of diffusion, which can be understood as the above. Figure 8 and Figure 9 One of them is the first diffusion unit 1231, and the other is the second diffusion unit 1232.

[0085] As described above, when the diffusion unit 1230 is formed in the first lens portion 1200, and the interval between the light source portion 1100 and the first lens portion 1200 is the same, such as Figure 10 As shown, when the diffusion unit 1230 is formed on the incident surface 1210 of the first lens section 1200, the distance d11 between adjacent light sources will be larger than the distance d12 between adjacent light sources when the diffusion unit 1230 is not formed on the incident surface 1210 of the first lens section 1200. As a result, the number of light sources required to emit light from the first lens section 1200 as a whole can be reduced, thereby reducing the number of components and cost.

[0086] Furthermore, when the diffusion unit 1230 is formed in the first lens section 1200, and the number of multiple light sources 1110 in the light source section 1100 is the same, such as Figure 11 As shown, when the diffusion unit 1230 is formed on the incident surface 1210 of the first lens portion 1200, the interval d21 between the light source portion 1100 and the first lens portion 1200 will be smaller than the interval d22 between the light source portion 1100 and the first lens portion 1200 when the diffusion unit 1230 is not formed on the incident surface 1210 of the first lens portion 1200. As a result, the overall size of the vehicle lamp 1 according to the present invention can be reduced, which is more conducive to miniaturization.

[0087] at this time, Figure 10 and Figure 11 This is an example of the case where the first diffusion unit 1231 is formed as diffusion unit 1230, and the same applies to the case where the second diffusion unit 1232 is formed as diffusion unit 1230.

[0088] The first lens portion 1200 may have a reflective layer 1221 formed on the emission surface 1220 to reflect light reflected from the rear by the second lens portion 1300 (described later) in a manner that allows the light to travel forward. A portion of the reflective layer 1221 may be removed to form a transmission region 1222 that allows a portion of the light incident on the first lens portion 1200 to be emitted.

[0089] The transmission region 1222 can be formed by removing a portion of the reflective layer 1221 through laser etching or the like. The illuminated image formed by the vehicle lamp 1 of this invention can be understood as being formed by light emitted from the transmission region 1222.

[0090] Figure 12 and Figure 13 This is a perspective view showing the second lens portion according to an embodiment of the present invention.

[0091] Reference Figure 12 and Figure 13According to an embodiment of the present invention, the second lens portion 1300 may include an incident surface 1310 into which light emitted from the first lens portion 1200 is incident and an exit surface 1320 into which light incident on the incident surface 1310 is emitted.

[0092] The second lens section 1300 may have a semi-reflective layer 1311 formed on the incident surface 1310, which transmits a portion of the light emitted from and incident on the first lens section 1200 and reflects the other portion.

[0093] As described above, since a reflective layer 1221 is formed on the emission surface 1220 of the first lens portion 1200, and a semi-reflective layer 1311 can be formed on the incident surface 1310 of the second lens portion 1300, a portion of the light emitted forward from the first lens portion 1200 can pass through the semi-reflective layer 1311 and travel forward, while another portion can be reflected backward by the semi-reflective layer 1311. The light reflected backward by the semi-reflective layer 1311 can repeatedly achieve the process of being reflected forward again by the reflective layer 1221 formed on the emission surface 1220 of the first lens portion 1200.

[0094] At this time, an original image with a shape corresponding to the transmission region 1222 can be formed by the light initially transmitted from the first lens section 1200 through the second lens section 1300. At least one reflected image of the original image can be formed by the light transmitted from the second lens section 1300 while being repeatedly reflected between the reflective layer 1221 and the semi-reflective layer 1311. As the number of reflections between the reflective layer 1221 and the semi-reflective layer 1311 increases, more reflected images can be formed. Thus, a illuminated image with a sense of three-dimensionality and depth can be formed by the original image and multiple reflected images.

[0095] Figure 14 This is a schematic diagram illustrating the light path of a vehicle lamp according to an embodiment of the present invention. Figure 15 This is a schematic diagram showing an illuminated image formed by a vehicle lamp according to an embodiment of the present invention.

[0096] Reference Figure 14 and Figure 15 In the vehicle lamp 1 according to an embodiment of the present invention, the illuminated image I formed by light L emitted forward from the light source 1100 may include an original image I1 having a shape corresponding to the transmission area 1222 and at least one reflected image I2 for the original image I1.

[0097] That is, the light L emitted from the light source 1100 can pass through the transmission area 1222 of the first lens 1200 and proceed to the second lens 1300. A portion of the light L L that travels to the second lens 1300, light L1, can pass through the semi-reflective layer 1311 of the second lens 1300 to form the original image I1, and another portion of the light L2 is reflected backward by the semi-reflective layer 1311. The light L2 reflected backward by the semi-reflective layer 1311 is reflected forward again by the reflective layer 1221 of the first lens 1200. A portion of the light L2 reflected forward by the reflective layer 1221, light L21, passes through the semi-reflective layer 1311 to form a reflected image I2 for the original image I1, and another portion of the light L22 can be reflected backward by the semi-reflective layer 1311.

[0098] At this time, since the reflected image I2 formed by more light reflected and transmitted between the reflective layer 1221 and the semi-reflective layer 1311 has relatively low brightness, the vehicle lamp 1 according to the present invention can form a illuminated image I with a sense of three-dimensionality and depth.

[0099] Furthermore, the illuminated area A used to form the illuminated image I when the vehicle lamp 1 of this utility model is illuminated can be as follows: Figure 16 The diagram shows a first illuminated area A1 and a second illuminated area A2. The first illuminated area A1 and the second illuminated area A2 can have different brightness levels. Thus, the illuminated image I formed by the vehicle lamp 1 of this invention can achieve a gradual effect of increasing or decreasing brightness from one side to the other in at least one direction.

[0100] In the embodiments of this utility model, the case in which the first illuminated area A1 corresponds to the first area 1121 of the substrate 1120 and the second illuminated area A2 corresponds to the second area 1122 of the substrate 1120 will be used as an example for explanation. Therefore, the case in which the area corresponding to the first illuminated area A1 in the illuminated image I has relatively high brightness will be used as an example for explanation.

[0101] At this time, since the plurality of first light sources 1111 disposed in the first region 1121 of the substrate 1120 are configured to have a higher density than the plurality of second light sources 1112 disposed in the second region 1122 of the substrate 1120, the illuminated image I formed by the vehicle lamp 1 of this invention is as follows: Figure 17 The area corresponding to the first illuminated area A1 has a higher brightness than the area corresponding to the second illuminated area A2, thus achieving a gradual effect of decreasing brightness from the first illuminated area A1 to the second illuminated area A2.

[0102] Furthermore, the aforementioned diffusion unit 1230 can be configured to have different diffusion degrees for the first illumination region A1 and the second illumination region A2.

[0103] Figure 18 This is a schematic diagram showing a diffusion unit formed in the first lens portion according to an embodiment of the present invention.

[0104] Reference Figure 18 According to an embodiment of the present invention, the diffusion unit 1230 may include a first diffusion unit 1231 and a second diffusion unit 1232.

[0105] The first lens portion 1200 may include a first pattern region P1 corresponding to the first illuminated region A1 and a second pattern region P2 corresponding to the second illuminated region A2, and the first pattern region P1 may correspond to the first region 1121 of the substrate 1120, and the second pattern region P2 may correspond to the second region 1122 of the substrate 1120.

[0106] At this time, the above-mentioned pattern can be formed in the first pattern region P1. Figure 8 The first diffusion unit 1231, and the above-mentioned features can be formed in the second patterned region P2. Figure 9 The second diffusion unit.

[0107] The first diffusion unit 1321 is formed in the first pattern area P1 because the plurality of first light sources 1111 disposed in the first area 1121 of the substrate 1120 are disposed at a higher density than the plurality of second light sources 1112 disposed in the second area 1122 of the substrate 1120. Therefore, even when the light path is held by the center portion 1231a of the first diffusion unit 1231, the first illuminated area A1 can emit light as a whole. Accordingly, the light held by the center portion 1231a through the travel path can form a relatively strong glittering gem-like effect.

[0108] Furthermore, the second diffusion unit 1232 is formed in the second pattern region P2 because the arrangement density of the plurality of second light sources 1112 is lower than that of the plurality of first light sources 1111. Therefore, in order for the light emitted from the plurality of second light sources 1112 to be emitted as a whole into the second illuminated region A2, a higher degree of diffusion than that of the first diffusion unit 1231 is required.

[0109] In addition, although the second diffusion unit 1232 has less light than the first diffusion unit 1231, the light path is maintained near the center. Therefore, it can achieve a gem-like effect with a lower brightness than the first diffusion unit 1231 while having a sparkling feel, thus achieving a uniform gem-like effect overall.

[0110] In the above embodiments, the example described is that the vehicle lamp 1 is installed on the exterior of the vehicle to indicate the vehicle's driving status. However, when the vehicle lamp 1 is used as decorative lighting inside the vehicle, it can be installed on the ceiling of the vehicle interior to ensure passenger visibility. In this case, as... Figure 19 As shown, taking into account the position of the passenger's eyes, the position of the book, etc., the first illuminated area A1 is preferably located at a set distance g in front of the headrest H of the vehicle seat.

[0111] That is, since the first illuminated area A1 has a relatively higher brightness than the second illuminated area A2, it is difficult to ensure the passenger's field of vision when the first illuminated area A1 is located behind the headrest H or too far away from the front of the headrest H. Therefore, the first illuminated area A1 can be located at a set distance g in front of the headrest H.

[0112] At this time, although Figure 19 The illustration shows a second illuminated area A2 located behind the first illuminated area A1, but this is merely an example for understanding the present invention and is not a limitation. The second illuminated area A2 may be located in front of or behind the first illuminated area A1.

[0113] In the above embodiment, the example described is that the gradient effect is achieved by making the arrangement density of the light sources different from each other, so that the corresponding areas in the illuminated image I have different brightness from each other, corresponding to the first illuminated area A1 and the second illuminated area A2. However, it is not limited to this. The brightness of the corresponding areas in the illuminated image I can also be made different from each other by changing the formation density of the diffusion unit 1230 formed in the first lens portion 1200.

[0114] Figure 20 This is a schematic diagram showing a diffusion unit formed in the first lens portion according to another embodiment of the present invention.

[0115] Reference Figure 20 In another embodiment of the present invention, the first lens portion 1200 may be formed such that the diffusion units 1230 have different densities in each of the first pattern region P1 and the second pattern region P2. In this case, the plurality of first light sources 1111 disposed in the first region 1121 of the substrate 1120 and the plurality of second light sources 1112 disposed in the second region 1122 of the substrate 1120 may be formed to have the same density.

[0116] That is, the higher the formation density of the diffusion unit 1230, the more light is maintained along the travel path. As a result, the regions in the illuminated image I corresponding to the first illuminated region A1 and the second illuminated region A2 have different brightness, thereby achieving a gradient effect.

[0117] In the above embodiments, although the cases in which the arrangement densities of the plurality of first light sources 1111 and the plurality of second light sources 1112 are different and the cases in which the densities of the diffusion units 1230 formed in the first pattern region P1 and the second pattern region P2 are different, the invention is not limited thereto. It is also possible to change the density of the diffusion units 1230 formed in the first pattern region P1 and the second pattern region P2 while changing the arrangement densities of the plurality of first light sources 1111 and the plurality of second light sources 1112, based on the brightness distribution of the illuminated image I formed by the vehicle lamp 1 of the present invention.

[0118] Furthermore, in the above embodiments, the vehicle lamp 1 is described as an example in which it may include a single lamp module 1000, but it is not limited thereto, and the vehicle lamp 1 may also include two or more lamp modules.

[0119] Figure 21 This is a schematic diagram illustrating a vehicle lamp according to yet another embodiment of the present invention.

[0120] Reference Figure 21 According to another embodiment of the present invention, the vehicle lamp 1 may include a first lamp module 1000 and a second lamp module 2000.

[0121] In another embodiment of this utility model, the first lamp module 1000 will be described as the lamp module 1000 of the above embodiment, and the second lamp module 2000 will be described as a lamp installed on a vehicle for lighting or signaling functions, and will be described as a headlight installed on both sides in front of the vehicle to illuminate light in the direction of travel of the vehicle to ensure forward visibility.

[0122] In another embodiment of this utility model, the case where the first lamp module 1000 is located in the central part of the front of the vehicle will be described as an example. This is because, in the case of a battery-powered electric vehicle, unlike an internal combustion engine vehicle, there is no need for a radiator grille for cooling the engine, so its space can be utilized.

[0123] The first lighting module 1000 is located in the grille section at the front of the vehicle. This is merely an example to help understand the present invention and is not limited thereto. The position and orientation of the first lighting module 1000 can be varied depending on the position of the second lighting module 2000.

[0124] In the first lighting module 1000, the first illuminated area A1 can be closer to the second lighting module 2000 than the second illuminated area A2. This is to achieve a differentiated appearance design through the gradient effect caused by the first lighting module 1000 while meeting regulations.

[0125] That is, the first lighting module 1000 is configured to be adjacent to one side of the various lights installed on the vehicle to achieve a gradient effect, thereby achieving an effect similar to the extension of the lights, thereby improving visibility and achieving a jewelry-like feel that provides a sparkling sensation, thus enhancing the aesthetic appeal.

[0126] Those skilled in the art to which this invention pertains will understand that this invention can be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above are exemplary in all respects and should be understood as not limiting. The scope of this invention is not limited by the foregoing detailed description, but by the claims. All modifications or variations derived from the meaning, scope, and equivalents of the claims should be interpreted as included within the scope of this invention.
