Abstract
Description
[0001] This application is a divisional application of the invention patent application filed on July 21, 2020, with application number 202010702556.0 and invention title "Guide Lights for Vehicles". Technical Field
[0002] This invention relates to a vehicle guide light, for example, a vehicle guide light that can form multiple guide patterns along the vehicle's direction of travel. Background Technology
[0003] Typically, vehicles are equipped with various vehicle guidance lights that have the following functions: illumination to easily identify objects around the vehicle while driving; and signaling to notify other vehicles or other road users of the vehicle's driving status.
[0004] Typically, the guide lights equipped on a vehicle can broadly include turn signal guide lights and reversing guide lights.
[0005] Turn signal lights are lights that are activated by the driver's operation of a multi-function switch when the vehicle is in motion. They serve to inform other vehicles of the vehicle's direction of travel when changing lanes or at intersections.
[0006] Reversing guide lights not only illuminate the area behind the driver when the gear lever is shifted into reverse (R), but also convey the intention to reverse to other vehicles to the side and rear.
[0007] However, existing guide lights are simply equipped by shining light from a light source outward through a lens. Therefore, they have the following drawbacks: when the guide lights of the preceding vehicle are in a blind spot that other drivers of vehicles located to the side and rear cannot see directly, it is impossible to know whether the guide lights are activated. In more serious cases, it is impossible to clearly know the lane change or reversing intention of the preceding vehicle, which may become the cause of an accident.
[0008] Furthermore, since existing guide lights have a structure that is added to existing vehicle lights (e.g., front lights and rear lights), there are problems such as insufficient installation space, inconvenience in assembly, and relatively complicated procedures.
[0009] Furthermore, while it can inform drivers of other vehicles or pedestrians who are not in the traffic blind spot of the vehicle's direction of travel, it has limitations in informing drivers of other vehicles or pedestrians who are in the traffic blind spot of the vehicle's direction of travel.
[0010] Therefore, there is a need for a solution that can easily inform drivers of other vehicles or pedestrians who have difficulty observing the direction of a particular vehicle, and a solution that simplifies the structure used to inform a particular vehicle of its direction of travel and can be universally applied to every vehicle.

[0076] The advantages, features, and methods for implementing the invention will become clear from the detailed embodiments described below in conjunction with the accompanying drawings. However, the invention is not limited to the embodiments disclosed below, which can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of the invention and to fully inform those skilled in the art of the scope of the invention, which is defined only by the claims. Throughout this specification, the same reference numerals refer to the same constituent elements.
[0077] Therefore, in several embodiments, in order to avoid the invention being misinterpreted, well-known process steps, well-known structures and well-known technologies are not specifically described.
[0078] The terminology used in this specification is intended to illustrate embodiments and not to limit the invention. In this specification, singular forms include plural forms unless specifically stated otherwise. The terms "comprises" and / or "comprising" as used in this specification mean that the presence or addition of more than one other constituent element, step, operation, and / or element besides those mentioned are not excluded. Furthermore, "and / or" includes each of the mentioned items and all combinations thereof.
[0079] Furthermore, the embodiments described in this specification will be explained with reference to cross-sectional views and / or schematic diagrams, which are idealized example drawings. Therefore, the form of the example drawings may vary depending on manufacturing techniques and / or allowable tolerances. Thus, the embodiments of the present invention are not limited to the specific forms illustrated, and variations in form resulting from manufacturing processes are also included. Moreover, in the various figures illustrated in this invention, the constituent elements may be shown in slightly enlarged or reduced form for ease of explanation.
[0080] Hereinafter, the present invention will be described with reference to the accompanying drawings illustrating a vehicle guide light 100 according to an embodiment of the present invention.
[0081] Figure 1 The figure schematically shows a vehicle 1 equipped with a vehicle guide light 100 according to an embodiment of the present invention.
[0082] According to an embodiment of the present invention, a vehicle guide light 100 can be installed at the front and rear of a vehicle 1 to display the shape of a light beam on the road surface along the direction of travel of the vehicle 1. For example, as The shape can be configured to form a pattern P on the road surface in the form of a beam along the front two sides of the vehicle 1 in the direction of travel. Furthermore, as... The shape can be configured to form a pattern P on the road surface in a beam shape along the direction of travel on the front center side of the vehicle 1. Furthermore, as with... or Different forms (e.g.) (Form), which can be configured to form a pattern P on the road surface in the form of a beam along both sides of the rear of vehicle 1 in the direction of travel. Furthermore, as... The form can be configured to form a pattern P on the road surface in the shape of a beam along the direction of travel on the rear central side of the vehicle 1.
[0083] The vehicle guide light 100 is a component that provides a means for informing other drivers of vehicle 1 or pedestrians on the road of the direction of travel of vehicle 1 to a predictable degree.
[0084] The direction of travel of vehicle 1 can be any of the following: turning left, turning right, or reversing. This can correspond to the expected direction of travel of vehicle 1 that you want to inform the driver of other vehicle 1 or pedestrians on the road who are in a traffic blind spot.
[0085] Furthermore, the direction of travel of vehicle 1 can also include either the left or right direction. Compared to the left and right turning directions, this is less likely to become an area that generates a traffic blind spot. However, informing vehicle 1 of its direction of travel through various means helps prevent traffic accidents. Therefore, either the left or right direction can also be included in the direction of travel of vehicle 1.
[0086] The vehicle guide light 100 of the present invention can be configured to inform other drivers or pedestrians of the vehicle 1’s entry from the left or right direction by means of conventional auxiliary light flashing, or it can be equipped separately from the conventional auxiliary light flashing configuration for informing the vehicle 1 of its direction.
[0087] Such vehicle guide lights 100 can be equipped separately according to the direction of travel of vehicle 1. For example, as described above, guide lights 100 may include the following: or Vehicle guide lights 100 corresponding to the current left and right turning directions in the direction of travel of vehicle 1; such as Vehicle guide lights 100 corresponding to the straight-ahead direction in the direction of travel of vehicle 1; such as or Vehicle guide lights 100 corresponding to the left and right turning directions when vehicle 1 is reversing; such as Vehicle guide lights 100 that correspond to the straight-ahead direction of the reverse direction in the direction of travel of vehicle 1.
[0088] Here, for or In this regard, the vehicle guide light 100 can be configured as a guide configuration located on the left or right side of the front or rear part of the vehicle 1 in the direction of travel, or it can be installed as a plurality of configurations adjacent to the vehicle lights 10 (e.g., turn signal lights) located on the left or right side of the front or rear part of the vehicle 1.
[0089] Similarly, for or In other words, it can be configured as a single configuration in the front or rear part of the vehicle guide light 100 for indicating the direction of travel forward or backward, or it can include a configuration for indicating the direction of travel located in the front or rear part of the vehicle 1.
[0090] For example, if the direction of travel of vehicle 1 is specifically intended to be a leftward turning direction, then by means of a leftward turning direction corresponding to the specific direction of travel of vehicle 1... The operation of the vehicle guide lights 100 can inform the drivers of other vehicles 1 or pedestrians on the road that vehicle 1 is expected to enter in the direction of a left turn.
[0091] Thus, vehicle 1 includes a plurality of vehicle guide lights 100. In this invention, it may also include an electronic control device, which is used to select a vehicle guide light 100 corresponding to a specific direction of travel according to the vehicle's direction of travel setting, and then activate the selected vehicle guide light 100.
[0092] Furthermore, it is preferable to have a configuration that simplifies the configuration of vehicle 1 as follows: by generating a guide beam that is displayed on the road surface in the form of a beam of light in order to inform other drivers or pedestrians of the direction of travel of vehicle 1, the guide beam that is displayed in the form of a beam of light in order to inform other drivers or pedestrians of the direction of travel of vehicle 1 is generated by a guide beam using a multiple pattern P of a light-emitting element, thereby simplifying the configuration of vehicle 1 for informing other drivers or pedestrians of the possibility of vehicle 1 entering nearby.
[0093] The following describes in detail the vehicle guide light 100 installed on the vehicle.
[0094] Figure 2This is a schematic perspective view of a vehicle guide light 100 according to an embodiment of the present invention.
[0095] Figure 3 This is a schematic exploded perspective view of a vehicle guide light 100 according to an embodiment of the present invention.
[0096] Figure 4 This is a schematic exploded plan view of a vehicle guide light 100 according to an embodiment of the present invention.
[0097] Figure 5 This is a schematic combined plan view of a vehicle guide light 100 according to an embodiment of the present invention.
[0098] Reference Figures 2 to 5 According to an embodiment of the present invention, a vehicle guide light 100 is configured to display the vehicle's direction of travel in a pattern on the road surface. Furthermore, the vehicle guide light 100 according to an embodiment of the present invention is configured to not only display the vehicle's direction of travel on the road surface but also simultaneously provide general auxiliary lighting (e.g., headlights, reversing lights, or turn signals). Moreover, the vehicle guide light 100 according to an embodiment of the present invention is positioned on the vehicle at a downward angle of 5 to 15 degrees relative to the horizontal line, enabling the display of a light distribution pattern or a guide pattern on the road surface.
[0099] According to an embodiment of the present invention, a vehicle guide light 100 may include a housing 110, a substrate portion 120, a light source portion 130, a first lens portion 140, a second lens portion 150, and a baffle portion 160.
[0100] The housing 110 can be divided into a first region 101 and a second region 102 adjacent to the first region 101. Inside the housing 110, there can be a dividing member 111 that divides the first region 101 and the second region 102 along the optical axis.
[0101] The dividing member 111 can be disposed from the front of the housing 110 to the front of the first lens portion 140, and can be configured to divide the vehicle guide light 100 into a configuration for guiding light distribution and a configuration for auxiliary light distribution.
[0102] The substrate portion 120 may be provided on the back side of the housing 110, and the light source portion 130, which will be described later, may be installed on the front side of the substrate portion 120.
[0103] The light source unit 130 may include a first light source module 131 and a second light source module 132.
[0104] The first light source module 131 may correspond to the position of the first region 101 and may include at least one light-emitting element mounted on the substrate portion 120. The second light source module 132 may correspond to the position of the second region 102 and may include at least one light-emitting element mounted on the substrate portion 120. (The following is a description of the process.) Figures 6 to 10 In this case, the first light source module 131 and the second light source module 132 can be described in detail.
[0105] The first lens portion 140 may be disposed on one side of the light source portion 130 and may be configured to receive light from the light source portion 130 and output it toward the second lens portion 150. The first lens portion 140 may include a first guide lens 141 and a first auxiliary lens 142. The first guide lens 141 and the first auxiliary lens 142 may be disposed as a single unit. The first lens portion 140 may refract light to receive the light source from the light source portion 130 and direct it in a straight line.
[0106] The first guide lens 141 may be configured to correspond to the first light source module 131 in the first region 101. The first guide lens 141 is a lens that enables the output of the first light source module 131 in a manner that forms a pattern at a position set on the road surface and can adjust the light emission range.
[0107] The first auxiliary lens 142 may be configured such that it is adjacent to the first guide lens 141 on one side and corresponding to the second light source module 132 in the second region 102. The first auxiliary lens 142 may be configured to receive light from the second light source module 132 and output a light distribution pattern toward the outside of the vehicle.
[0108] The second lens portion 150 may be configured to be mounted on the front of the housing 110 and to receive light emitted from the first lens portion 140 and output it outward. The second lens portion 150 may also be configured to receive light emitted from the first lens portion 140 and flip it vertically for output. The second lens portion 150 may include a second guide lens 151 and a second auxiliary lens 152.
[0109] The second guide lens 151 may be arranged in front of the first guide lens 141 in the first region 101. The second guide lens 151 may be configured to receive light emitted from the first guide lens 141 and direct it toward a position set on the road surface.
[0110] The second auxiliary lens 152 may be arranged in front of the first auxiliary lens 142 in the second region 102. The second auxiliary lens 152 may be configured to receive light output from the first auxiliary lens 142 and illuminate the outer side of the vehicle to form a light distribution pattern.
[0111] The baffle portion 160 may be located between the first guide lens 141 and the second guide lens 151 in the first region 101. The baffle portion 160 may be configured to form a design pattern on the road surface, and its size may be determined, and it may block the inflow of light other than the pattern. That is, for light output from the first lens portion 140, the baffle portion 160 can block the light from outputting from the portion outside the pattern shape, and cause the light to flow only into the portion according to the pattern shape, and then be transmitted to the second lens portion 150.
[0112] The specific configurations of the first lens section 140, the second lens section 150, and the baffle section 160 can be described in the following description. Figures 6 to 15 Please provide a detailed explanation later.
[0113] Figure 6 This is a schematic perspective view showing the stacked state of the substrate portion 120, the light source portion 130, the first lens portion 140, and the baffle portion 160 in a vehicle guide light 100 according to an embodiment of the present invention. Figure 7 This is a schematic front view of the substrate portion 120 and the light source portion 130 in a vehicle guide light 100 according to an embodiment of the present invention. Figure 8 This is a schematic plan view of the first lens portion 140 in a vehicle guide light 100 according to an embodiment of the present invention. Figure 9 This is a schematic front view showing the stacked state of the substrate portion 120, the light source portion 130, the first lens portion 140, and the baffle portion 160 in a vehicle guide light 100 according to an embodiment of the present invention.
[0114] Reference Figures 6 to 9 According to one embodiment of the present invention, the light source unit 130 is arranged on the substrate unit 120 in a direction perpendicular to the optical axis, and can be divided into a first light source module 131 in the first region 101 and a second light source module 132 in the second region 102. Furthermore, the first light source module 131 may be located higher than the second light source module 132.
[0115] First, the first light source module 131 may be equipped with multiple light-emitting elements, and may be mounted on the upper side of the substrate portion 120 from the outermost periphery towards the second region 102. For example, in one embodiment of the present invention, the first light source module 131 may include three light-emitting elements (specifically, a first light-emitting element 1311, a second light-emitting element 1312, and a third light-emitting element 1313). The light-emitting element equipped on one side of the first region 101 (e.g., the leftmost position in the figure) may be referred to as the first light-emitting element 1311, and may be referred to as the second light-emitting element 1312 and the third light-emitting element 1313 in the order adjacent to the first light-emitting element 1311.
[0116] The light-emitting element 1311 to the third light-emitting element 1313 can be disposed towards the upper side of the substrate portion 120. That is, the second light-emitting element 1312, which is adjacent to the first light-emitting element 1311, can be separated from the first light-emitting element 1311 by a predetermined distance in the right direction and can be located in an upper direction than the first light-emitting element 1311. Similarly, the third light-emitting element 1313, which is adjacent to the second light-emitting element 1312, can be separated from the second light-emitting element 1312 by a predetermined distance in the right direction and can be located in a predetermined upper direction than the second light-emitting element 1312. The first light source module 131 according to an embodiment of the present invention is described as having three light-emitting elements as an example; however, it is not limited to this, and the number can be arbitrarily changed or modified according to the pattern or position formed on the road surface.
[0117] The second light source module 132 may be equipped with multiple light-emitting elements. The light-emitting elements of the second light source module 132 may be arranged adjacent to each other, with the outermost light-emitting element positioned higher than the others. For example, according to an embodiment of the present invention, the second light source module 132 may sequentially include three light-emitting elements (specifically, a fourth light-emitting element 1321, a fifth light-emitting element 1322, and a sixth light-emitting element 1323) to the right of the first light source module 131.
[0118] The fourth light-emitting element 1321 and the fifth light-emitting element 1322 can be arranged spaced apart from each other and at the same height, while the sixth light-emitting element 1323, located on the outermost side, can be positioned higher than the fourth and fifth light-emitting elements 1321 and 1322. The purpose of placing the sixth light-emitting element 1323 above the other light-emitting elements is as follows: when the light-emitting elements are arranged at the same horizontal level, the brightness and luminance of the area irradiated towards the upper side of the pattern are insufficient during auxiliary light distribution. Therefore, placing the sixth light-emitting element 1323 above the pattern compensates for the insufficient brightness and luminance of the upper side. Thus, the number or arrangement of the light-emitting elements in the second light source module 132 can be arbitrarily changed or modified.
[0119] As described above, according to an embodiment of the present invention, the first lens portion 140 may include a lens plate 143 forming lenses (the first guide lens 141 and the first auxiliary lens 142 described above) on the front of the substrate portion 120 on which the light source portion 130 is mounted. In the lens plate 143, the first guide lens 141 and the first auxiliary lens 142 may be formed as a single unit and arranged adjacent to each other in a direction perpendicular to the optical axis.
[0120] The lens plate 143 may include: a first guide lens region 143a, which is equipped with a first guide lens 141 corresponding to the first region 101; and a first auxiliary lens region 143b, which is equipped with a first auxiliary lens 142 corresponding to the second region 102.
[0121] The lens plate 143 of the first guiding lens region 143a can be configured such that it forms a stepped arrangement from the outermost side toward the second region 102, corresponding to the light-emitting element of the first light source module 131. For example, the first portion of the lens plate 143 forming the first lens 1411, the second portion of the lens plate 143 forming the second lens 1412, and the third portion of the lens plate 143 forming the third lens 1413 can be formed with a stepped arrangement between them, thus allowing them to be arranged in a stepped manner. Therefore, it can be implemented such that the second portion protrudes forward relative to the first portion, and the third portion protrudes forward relative to the second portion. Furthermore, the first auxiliary lens region 143b is adjacent to the third portion and forms a stepped arrangement with it, so that the lens plate 143 of the first auxiliary lens region 143b can protrude forward relative to the third portion. Although described later, the lenses formed in the first guide lens region 143a (i.e., the first lens 1411, the second lens 1412, and the third lens 1413) are formed in different sizes, and the first light source module 131 is formed on the same plane. Accordingly, the first light source module 131 should have its focal length adjusted to be the same according to the focal point of the lens shape. For this purpose, the lens plate 143 of the first guide lens region 143a can form a step.
[0122] The first auxiliary lens region 143b may be equipped with the first auxiliary lens 142 corresponding to the second region 102, and as described above, may be configured to form a step at the end of the first guide lens region 143a (specifically, the third portion).
[0123] The first auxiliary lens region 143b may be equipped with the first auxiliary lens 142 so as to form the same plane and correspond to the light-emitting element of the second light source module 132.
[0124] The first auxiliary lens 142 can be formed with the same lens shape on the same plane as the lens plate 143. The first auxiliary lens 142 can be positioned coaxially with the optical axis of the light-emitting element of the second light source module 132. Since the outermost light-emitting element in the second light source module 132 is located on the upper side of the substrate portion 120 compared to other light-emitting elements, the outermost first auxiliary lens 142 can be positioned higher than the other first auxiliary lenses 142, thereby allowing the optical axis to be located at a higher position. For example, the first auxiliary lens 142 can include a fourth lens 1421, a fifth lens 1422, and a sixth lens 1423 corresponding to the fourth light-emitting element 1321, the fifth light-emitting element 1322, and the sixth light-emitting element 1323. Accordingly, the fourth lens 1421, the fifth lens 1422 and the sixth lens 1423 can be formed on the same plane using the same lens, and the fourth lens 1421 and the fifth lens 1422 can be formed at the same horizontal position, and the sixth lens 1423 can be located on the upper side than the fourth lens 1421 and the fifth lens 1422.
[0125] As described above, the first lens portion 140 can be arranged on the front side of the light source portion 130, the first guide lens 141 can be provided on the front side of the first light source module 131 in the first region 101, and the first auxiliary lens 142 can be provided on the front side of the second light source module 132 in the second region 102.
[0126] The first guide lens 141 can be configured to adjust the position and light emission range of the pattern displayed on the road surface by means of its lens shape. Specifically, the first guide lens 141 has different lens designs for each corresponding light emission element, thereby adjusting the position or light emission range of the pattern displayed on the road surface. Furthermore, the first guide lens 141 can be positioned coaxially with the optical axis of the light emission element of the first light source module 131. It can also be configured such that its size increases from the outermost side to the first auxiliary lens 142 side. For example, the first guide lens 141 can include a first lens 1411, a second lens 1412, and a third lens 1413 corresponding to the light emission elements of the first light source module 131 (specifically, the first light emission element 1311 to the third light emission element 1313).
[0127] As described above, the lens size increases from the first lens 1411 to the third lens 1413. Furthermore, from the first light-emitting element 1311 to the third light-emitting element 1313, the first light-emitting element 1311 to the third light-emitting element 1313 can become increasingly positioned upwards on the substrate portion 120. Since the first guide lens 141 is coaxial with its respective light-emitting element, the first lens 1411 to the third lens 1413 can become increasingly positioned upwards as they move from the first lens 1411 towards the third lens 1413.
[0128] That is, the second lens 1412 may be adjacent to the first lens 1411 and located on the upper side compared to the first lens 1411, and the third lens 1413 may be adjacent to the second lens 1412 and located on the upper side compared to the second lens 1412.
[0129] As described above, the step size of the lens plate 143 in the first guide lens region 143a and the lens size of the first guide lens 141 can be arbitrarily changed or deformed according to the pattern to be realized on the road surface.
[0130] Figure 10 This is an enlarged front view of the substrate portion 120, the light source portion 130, the first lens portion 140, and the baffle portion 160 of the first region 101 in a vehicle guide light 100 according to an embodiment of the present invention. Figure 11 This is a schematic diagram illustrating a pattern formed on the road surface in a vehicle guide light 100 according to an embodiment of the present invention. Figure 12 This is a schematic diagram showing the shape of the guide pattern hole 162 in the baffle portion 160 of a vehicle guide light 100 according to an embodiment of the present invention. Figure 13 This is a diagram showing a pattern formed on the road surface in a vehicle guide light 100 according to a guide pattern hole 162 of a baffle portion 160, according to an embodiment of the present invention.
[0131] Reference Figures 10 to 13 According to an embodiment of the present invention, the baffle portion 160 may be located in the first region between the first guide lens 141 and the second guide lens 151, and may be configured to form a pattern displayed on the road surface and limit glare.
[0132] The baffle portion 160 may be formed with a baffle plate 161 and a guide pattern hole 162.
[0133] The blocking plate 161 may be located between the first guide lens 141 and the second guide lens 151. The blocking plate 161 may be configured to block light emitted from the first guide lens 141 from being exposed outside a predetermined position (guide pattern hole 162 described later).
[0134] The guide pattern hole 162 can be provided on the block plate 161. The guide pattern hole 162 can correspond to the light-emitting element of the first guide lens 141 and correspond to the pattern and size formed on the road surface.
[0135] The guide pattern holes 162 can be configured to correspond to the first light source module 131 (specifically, the light-emitting elements of the first light source module 131). For example, since the first light source module 131 has three light-emitting elements, namely the first light-emitting element 1311, the second light-emitting element 1312, and the third light-emitting element 1313, the guide pattern holes 162 are also provided in the baffle portion 160 as three (specifically, the first guide pattern hole 1621, the second guide pattern hole 1622, and the third guide pattern hole 1623).
[0136] Furthermore, the first guide pattern hole 1621, the second guide pattern hole 1622, and the third guide pattern hole 1623 can be formed adjacent to each other at the same horizontal position on the baffle plate 161. Simultaneously, the length of the guide pattern hole 162 from top to bottom can correspond to the position of the light-emitting element in the first light source module 131. Moreover, the guide pattern hole 162 can create different bright spot areas depending on the position of the light-emitting element.
[0137] For example, in the first guide pattern hole 1621, the first light-emitting element 1311 and the first lens 1411 can be located at the lowermost part of the first guide pattern hole 1621. Accordingly, the light emitted from the first light-emitting element 1311 can have the brightest intensity at the lowermost part of the first guide pattern hole 1621, and the lowermost part of the first guide pattern hole 1621 can become a bright spot area.
[0138] Furthermore, in the second guide pattern hole 1622, the second light-emitting element 1312 and the second lens 1412 can be located in the central portion between the upper and lower sides of the guide pattern hole 1622. Accordingly, the light emitted from the second light-emitting element 1312 can have the brightest intensity in the central portion of the second guide pattern hole 1622, and the central portion of the second guide pattern hole 1622 can become a bright spot area.
[0139] Furthermore, in the third guide pattern hole 1623, the third light-emitting element 1313 and the third lens 1413 can be located at the uppermost part of the third guide pattern hole 1623. Accordingly, the light emitted from the third light-emitting element 1313 can have the brightest intensity at the uppermost part of the third guide pattern hole 1623, and the uppermost part of the third guide pattern hole 1623 can become a bright spot area of light.
[0140] According to an embodiment of the present invention, the guide pattern hole 162 can be formed into various shapes depending on the shape of the pattern formed on the road surface. For example, such as Figure 12 (a) The guide pattern hole 162 can be formed as an inverted trapezoidal opening. Accordingly, a pattern can be formed on the road surface as shown in the diagram. Figure 13 The guiding pattern of (a). And, as... Figure 12 (b) The guide pattern hole 162 can be formed as a plurality of gradually decreasing openings in an inverted stepped shape. Accordingly, a pattern can be formed on the road surface as shown in the figure. Figure 13 The guiding pattern of (b). And, as... Figure 12 (c) The guide pattern hole 162 can be formed as a plurality of gradually decreasing openings in the shape of a boomerang. Accordingly, a pattern can be formed on the road surface as shown in the diagram. Figure 13 (c) is the guide pattern.
[0141] Figure 14 This is a schematic diagram of the second lens portion 150 in a vehicle guide light 100 according to an embodiment of the present invention.
[0142] Refer to together Figure 14 And the previous ones Figures 2 to 5 As described above, according to an embodiment of the present invention, the second lens portion 150 may have a structure that is spaced apart from the first lens portion 140 and mounted on the front of the housing 110. Furthermore, the second lens portion 150 may include a second guide lens 151 and a second auxiliary lens 152, which may be integrally arranged adjacent to each other on the same plate.
[0143] The second guide lens 151, as part of the first region 101 arranged in the second lens portion 150, can be arranged in front of the baffle portion 160 in front of the first guide lens 141.
[0144] The second auxiliary lens 152, as part of the second region 102 arranged in the second lens section 150, can be arranged in front of the first auxiliary lens 142.
[0145] Therefore, observing the first region 101, it can have a structure in which the first light source module 131, the first guide lens 141, the baffle portion 160, and the second guide lens 151 are stacked in that order. Observing the second region 102, it can have a structure in which the second light source module 132, the first auxiliary lens 142, and the second auxiliary lens 152 are stacked in that order.
[0146] The second lens portion 150 may be formed with exit surfaces 151a and 152a and incident surfaces 151b and 152b. Specifically, incident surface 151b and exit surface 151a may be realized in the first region 101, and incident surface 152b and exit surface 152a may be realized in the second region 102.
[0147] In this invention, the emission surfaces 151a and 152a of the second lens portion 150 can be formed as raised emission surfaces protruding upwards, downwards, leftwards, and rightwards. That is, the emission surface 151a of the second guide lens 151 in the first region 101 and the emission surface 152a of the second auxiliary lens 152 in the second region 102 can be similarly formed as raised emission surfaces protruding upwards, downwards, leftwards, and rightwards.
[0148] Furthermore, in this invention, the incident surfaces 151b and 152b of the second lens portion 150 can be implemented in different forms in the second guide lens 151 and the second auxiliary lens 152. Specifically, the incident surface 151b of the second guide lens 151 can be formed as a planar incident surface, so that the light passing through the baffle portion 160 can be flipped up and down to illuminate the road surface. Furthermore, the incident surface 152b of the second auxiliary lens 152 can be formed as a convex incident surface protruding along the length direction (lateral) to diffuse the light and satisfy the light distribution requirements. Here, the length direction (lateral) refers to the left-right length direction when viewing the lamp from the front, that is, the horizontal direction perpendicular to the length direction of the vehicle body.
[0149] Figure 15 This is a combined cross-sectional view showing the position of the first light-emitting element 1311 in a vehicle guide light 100 according to an embodiment of the present invention. Figure 16 This is a combined cross-sectional view showing the position of the second light-emitting element 1312 in a vehicle guide light 100 according to an embodiment of the present invention. Figure 17 This is a combined cross-sectional view of the position of the third light-emitting element 1313 in a vehicle guide light 100 according to an embodiment of the present invention.
[0150] As mentioned above, refer to Figures 15 to 17The base plate portion 120, the light source portion 130, the first lens portion 140, the baffle portion 160, and the second lens portion 150 are integrated into a housing 110, and these can be divided into a first region 101 and a second region 102 by a dividing member 111. Accordingly, the vehicle guide light 100 can be divided into a portion that forms a guide pattern on the road surface (first region 101) and a region that realizes the light distribution of the vehicle (second region 102), and both functions can be achieved with a single structure.
[0151] As described above, the first region 101 can have a structure in which the first light source module 131, the first guide lens 141, the baffle portion 160, and the second guide lens 151 are stacked in that order. The second region 102 can have a structure in which the second light source module 132, the first auxiliary lens 142, and the second auxiliary lens 152 are stacked in that order.
[0152] Furthermore, since the vehicle guide light 100 is installed on the vehicle at a downward tilt of approximately 5 to 15 degrees (preferably around 10 degrees), it can emit light towards the road surface. In this regard, the second region 102 of the vehicle guide light 100 functions as an auxiliary light for the vehicle, while the first region 101 functions as a guide light.
[0153] Specifically, observe the light emission of the first light-emitting element 1311 in the first region 101, such as... Figure 15 The light from the first light-emitting element 1311 of the first light source module 131 can be output from the lower side of the substrate portion 120 to the first lens 1411, which has the smallest lens and is coaxial with the position of the first light-emitting element 1311. The first lens 1411 receives the light output from the first light-emitting element 1311 and directs the light towards the lowermost part of the baffle portion 160 (specifically, the first guide pattern hole 1621), so that it can be output from the convex emission surface through the planar incident surface of the second guide lens 151.
[0154] The light emitted from the second guide lens 151 through the first light-emitting element 1311 can achieve the brightest pattern on the road surface closest to the vehicle (see reference). Figure 11 (b)
[0155] Furthermore, in the first region 101, the emission of light from the second light-emitting element 1312 is specifically observed, such as... Figure 16The light from the second light-emitting element 1312 of the first light source module 131 can be output from the central position of the substrate portion 120 to the second lens 1412, which has a lens larger than the first lens 1411 and smaller than the third lens 1413 and is coaxial with the position of the second light-emitting element 1312. The second lens 1412 receives the light output from the second light-emitting element 1312 and directs the light toward the central portion of the baffle portion 160 (specifically, the second guide pattern hole 1622), so that it can be output from the convex emission surface through the planar incident surface of the second guide lens 151.
[0156] The light emitted from the second guide lens 151 via the second light-emitting element 1312 can achieve the brightest pattern on the road surface farther from the vehicle compared to the pattern formed by the first light-emitting element 1311 on the road surface (see reference). Figure 11 (c)).
[0157] Furthermore, in the first region 101, the emission of light from the third light-emitting element 1313 is specifically observed, such as... Figure 17 The light from the third light-emitting element 1313 of the first light source module 131 can be output from the upper side of the substrate portion 120 to the third lens 1413 of the first guide lens 141, which has the largest lens and is coaxial with the position of the third light-emitting element 1313. The third lens 1413 receives the light output from the third light-emitting element 1313 and directs the light towards the uppermost part of the baffle portion 160 (specifically, the third guide pattern hole 1623), so that it can be output from the convex emission surface through the planar incident surface of the second guide lens 151.
[0158] The light emitted from the third lens 1413 via the third light-emitting element 1313 can achieve the brightest pattern on the road surface, farther from the vehicle than the pattern formed by the first light-emitting element 1311 on the road surface (see reference). Figure 11 (d)
[0159] Therefore, the final pattern formed on the road surface can be formed by focusing the light emitted from the first light-emitting element 1311, the second light-emitting element 1312, and the third light-emitting element 1313. Figure 11 (a)
[0160] The embodiments of the present invention have been described above with reference to the accompanying drawings. Those skilled in the art will understand that the present invention can be implemented in other specific forms without altering the technical concept or essential features. Therefore, the embodiments described above are exemplary in all respects and should be understood as not being limiting.
