Description

Technical Field

[0001] This invention relates to a vehicle lamp, and more specifically, to a vehicle lamp capable of achieving an optimal beam pattern while realizing a slim design. Background Technology

[0002] Typically, vehicles are equipped with various lights to facilitate the identification of objects around the vehicle when driving at night and to signal the vehicle's status to other vehicles or pedestrians.

[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 various lights are stipulated by regulations to ensure that each light fully performs its function.

[0004] Recently, in addition to the basic function of vehicle lights in assisting safe driving by ensuring driver visibility, the aesthetic aspects that consumers perceive through improved exterior design have also had a significant impact on their decision to purchase a vehicle.

[0005] To this end, research is being actively conducted to enable vehicle lighting fixtures to form optimal beam patterns while having a slimmer profile.

[0016] The first lens portion may further include an additional reflective portion that reflects light emitted from the plurality of guide modules, causing a portion of the light to travel toward the second lens portion, thereby expanding the beam pattern along one side.

[0017] The additional reflective portion may be configured to extend forward from the lower part of the ejection portion of each of the plurality of guide modules.

[0018] The emission portion of each of the plurality of guiding modules can be arranged to form a single column along a direction parallel to the column formed by the plurality of light sources.

[0052] Hereinafter, the present invention will be described with reference to the accompanying drawings, which are used to describe vehicle lighting fixtures, based on embodiments of the present invention.

[0053] Figure 1 and Figure 2 This is a perspective view showing a vehicle lamp according to an embodiment of the present invention. Figure 3 This is a plan view illustrating a vehicle lamp according to an embodiment of the present invention. Figure 4 yes Figure 3 A cross-sectional view of line A-A'. Figure 5 yes Figure 3 A cross-sectional view of line B-B'.

[0054] Reference Figures 1 to 5 According to an embodiment of the present invention, a vehicle lamp 1 may include a plurality of light sources 1000, a first lens portion 2000 and a second lens portion 3000. The example described is based on the case where the X-axis represents the vehicle width direction as left and right, the Y-axis represents the driving direction as front and back, and the Z-axis represents the vehicle height direction as up and down. However, it is not limited to this. According to the installation direction or position of the vehicle lamp 1 of the present invention, the actual directions represented by the X-axis, Y-axis and Z-axis may be changed.

[0055] In an embodiment of the present invention, the vehicle lamp 1 is described as an example of a headlight used to ensure the driver's forward visibility when the vehicle is driving at night or in a dark place such as a tunnel. However, it is not limited to this. The vehicle lamp 1 of the present invention can be used not only as a headlight, but also as a taillight, brake light, daytime running light, turn signal light, fog light, reversing light, position light and other lamps installed on the vehicle. The vehicle lamp 1 of the present invention can be used for any one of the above-mentioned uses, or it can be used for two or more uses at the same time.

[0056] When the vehicle lamp 1 of the present invention is used as a headlight, in order to avoid glare to the driver of a vehicle in front, such as a vehicle ahead or an oncoming vehicle, at least one of the following can be generated: a low beam pattern that ensures a wide field of vision at close range in front of the vehicle by illuminating light downwards based on a cutoff line of a predetermined shape, and a high beam pattern that ensures a long field of vision at far range in front of the vehicle by positioning at least a portion above the cutoff line. Typically, the low beam pattern is formed together with the high beam pattern to simultaneously ensure a wide field of vision at close range in front of the vehicle and a long field of vision at far range in front of the vehicle.

[0057] Hereinafter, in the embodiments of the present invention, as Figure 6 As shown, the following example will be used for explanation: The vehicle lamp 1 of the present invention forms a high beam pattern P with at least a portion located on the upper side, based on the cutoff line CL, and with... Figure 6 The high beam pattern P is illustrated by taking the light beam pattern formed by light shining onto a screen located at a set distance in front of the vehicle as an example.

[0058] The high beam pattern P can be formed by multiple pattern areas PA created by light emitted from each of multiple light sources 1000, and depending on the position of the vehicle in front, at least one of the multiple light sources 1000 can be turned off to create a shadow area to avoid glare for the driver of the vehicle in front.

[0059] Multiple light sources 1000 can be disposed on a common substrate (not shown) and arranged to form at least one column R1, R2 extending in the left-right direction. In an embodiment of the present invention, the case in which a first column R1 and a second column R2 located below the first column R1 are formed by the multiple light sources 1000 will be described as an example.

[0060] At this point, although the example given is a case where multiple light sources 1000 use semiconductor light-emitting elements such as light-emitting diodes (LEDs), it is not limited to this. Multiple light sources 1000 may use not only LEDs, but also various light sources such as bulbs or laser diodes (LDs). Furthermore, depending on the type of light source, optical elements such as reflectors, phosphors, mirrors, and prisms may be added to adjust the path, brightness, color, etc. of the light.

[0061] Furthermore, the case where multiple light sources 1000 are disposed on a common substrate can be understood as such that the optical axes of the multiple light sources 1000 are arranged parallel to each other.

[0062] In an embodiment of the present invention, the case in which two columns R1 and R2 are formed by multiple light sources 1000 is used as an example for explanation. However, this is only an example to help understand the present invention and is not limited thereto. The number of columns formed by multiple light sources 1000 can be varied according to the light distribution characteristics required in the beam pattern formed by the vehicle lamp 1 of the present invention or the layout of the vehicle lamp 1 of the present invention. The light distribution characteristics can include the position, size, shape, brightness, etc. of the area illuminated by the light.

[0063] Among the multiple light sources 1000, the light source 1100 belonging to the first column R1 and the light source 1200 belonging to the second column R2 can be arranged alternately in a staggered manner along the left-right direction, as described above. Figure 6 As shown, this is to make each of the multiple patterned regions PA staggered from each other.

[0064] In the following embodiments of the present invention, the light source 1100 belonging to the first column R1 among the plurality of light sources 1000 is referred to as the "first light source", and the light source 1200 belonging to the second column R2 among the plurality of light sources 1000 is referred to as the "second light source".

[0065] The first lens section 2000 can be located in front of the multiple light sources 1000 and serves to adjust the path of light so that the light emitted from the multiple light sources 1000 travels to the second lens section 3000 located in front of the first lens section 2000.

[0066] In an embodiment of the present invention, the case in which the first lens portion 2000 is located in front of the plurality of light sources 1000 and the second lens portion 3000 is located in front of the first lens portion 2000 is an example of a case in which the direction of the light irradiated from the vehicle lamp 1 of the present invention is assumed to be in front. According to the installation position or direction of the vehicle lamp 1 of the present invention, the actual direction represented by "in front" can be changed.

[0067] The first lens section 2000 may include a plurality of guide modules 2100 for adjusting the path of light emitted from each of a plurality of light sources 1000, and the plurality of guide modules 2100 may be integrally formed with each other.

[0068] In the embodiments of the present invention, the case in which the first light source 1100 and the second light source 1200 are alternately arranged in a staggered manner along the left and right direction will be described as an example. Therefore, for the multiple guide modules 2100, the case in which the guide module 2110 corresponding to the first light source 1100 and the guide module 2120 corresponding to the second light source 1200 are alternately arranged along the left and right direction will also be described as an example. Hereinafter, in the embodiments of the present invention, the guide module 2110 corresponding to the first light source 1100 will be referred to as the "first guide module", and the guide module 2120 corresponding to the second light source 1200 will be referred to as the "second guide module".

[0069] The first guiding module 2110 may include a first incident section 2111, a first ejection section 2112, and a first transmission section 2113.

[0070] The first incident portion 2111 may include a central surface 2111a with the optical axis of the first light source 1100 as the central axis C11, a protruding surface 2111b protruding from the central surface 2111a toward the first light source 1100, and a reflecting surface 2111c reflecting light incident on the protruding surface 2111b in such a way that the light travels forward.

[0071] The first emission section 2112 can emit light that has been incident on the first incident section 2111 and transmitted through the first transmission section 2113, and can have a forward-protruding shape to focus the emitted light.

[0072] In an embodiment of the present invention, the central axis C11 of the first incident portion 2111 and the central axis C12 of the first emission portion 2112 may be parallel to the front-back direction, and the central axis C11 of the first incident portion 2111 may be set to be spaced upward relative to the central axis C12 of the first emission portion 2112. This is to achieve a slim appearance design while improving light efficiency, and a detailed description of this will be given later.

[0073] The first transmission section 2113 can reflect light incident on the first incident section 2111 at least once and transmit it to the first emission section 2112.

[0074] like Figure 7As shown, the first transmission section 2113 may include: a primary reflecting surface 2113a, which reflects the light L1 incident on the first incident section 2111 and traveling forward, causing it to travel in a downward direction; and a secondary reflecting surface 2113b, which reflects the light reflected by the primary reflecting surface 2113a, causing it to travel forward toward the first emission section 2112. The primary reflecting surface 2113a is formed to gradually tilt from the rear end toward the front end along a direction close to the central axis C12 of the first emission section 2112 (i.e., downward in front). The secondary reflecting surface 2113b is the same as the primary reflecting surface 2113a, and is formed to gradually tilt from the front end toward the rear end along a direction close to the central axis C11 of the first incident section 2111 (i.e., upward in rear).

[0075] Furthermore, the secondary reflecting surface 2113b is positioned closer to the first emission portion 2112 than the primary reflecting surface 2113a, so that the light reflected by the primary reflecting surface 2113a is reflected toward the first emission portion 2112.

[0076] At this time, the first transmission unit 2113 may make at least one of the primary reflection surface 2113a and the secondary reflection surface 2113b consist of a plurality of reflection regions A1, A2, A3 having different reflection characteristics from each other. The different reflection characteristics of each of the plurality of reflection regions A1, A2, A3 can be understood as at least one of the angles or curvatures being formed to be different from each other, so that at least one of the light travel direction or the light concentration is different from each other.

[0077] In an embodiment of the present invention, the case in which the secondary reflective surface 2113b of the first transmission section 2113 includes multiple reflective regions A1, A2, and A3 with different reflective characteristics will be described as an example. This is because, when the secondary reflective surface 2113b has a planar shape, as shown by the dashed arrow, a portion of the light reflected by the secondary reflective surface 2113b will travel in a direction deviating from the first emission section 2112 and cause light loss. Therefore, it is necessary to ensure that the light reflected by the secondary reflective surface 2113b passes through the first emission section 2112 and proceeds to the second lens section 3000 with as little loss as possible, thereby improving light efficiency.

[0078] The second guiding module 2120 may include a second incident section 2121, a second ejection section 2122, and a second transmission section 2123.

[0079] Similar to the first incident part 2111, the second incident part 2121 may include: a central surface 2121a with the optical axis of the second light source 1200 as the central axis C21, a protruding surface 2121b protruding from the central surface 2121a toward the second light source 1200, and a reflecting surface 2121c reflecting the light incident on the protruding surface 2121b so that it travels forward.

[0080] The second emission section 2122 can emit light that has been incident on the second incident section 2121 and transmitted through the second transmission section 2123, and can have a forward-protruding shape to focus the emitted light.

[0081] In an embodiment of the present invention, the central axis C21 of the second incident portion 2121 may be set to be spaced downward relative to the central axis C22 of the second emitting portion 2122. This is to achieve a slim appearance design while improving light efficiency, and a detailed description of this will be given later.

[0082] like Figure 8 As shown, the second transmission section 2123 may include: a primary reflecting surface 2123a, which reflects the light L2 incident on the second incident section 2121 and traveling forward, causing it to travel in a downward direction; and a secondary reflecting surface 2123b, which reflects the light reflected by the primary reflecting surface 2123a, causing it to travel forward toward the second emission section 2122. The primary reflecting surface 2123a is formed to gradually tilt in a direction close to the central axis C22 of the second emission section 2122 (i.e., the upper front side) as it moves from the rear end to the front end. The secondary reflecting surface 2123b is the same as the primary reflecting surface 2123a, and is formed to gradually tilt in a direction close to the central axis C21 of the second incident section 2121 (i.e., the lower rear side) as it moves from the front end to the rear end.

[0083] Furthermore, the secondary reflecting surface 2123b can be configured to be closer to the second emission portion 2122 than the primary reflecting surface 2123a, so that the light reflected by the primary reflecting surface 2123a is reflected to the second emission portion 2122.

[0084] At this time, similar to the first transmission section 2113 described above, the second transmission section 2123 may be composed of at least one of the primary reflection surface 2123a and the secondary reflection surface 2123b, which are composed of multiple reflection regions A1, A2, A3 with different reflection characteristics, so that the light reflected by the second reflection surface 2123b can be emitted through the second emission section 2122 with as little loss as possible.

[0085] like Figure 9As shown, the first guide module 2110 and the second guide module 2120 described above can be arranged such that the first emission portion 2112 and the second emission portion 2122 form a single column along the forming direction (i.e., the left-right direction) of at least one column R1, R2 where a plurality of light sources 1000 are arranged. Thus, light emitted from the first light source 1100 belonging to the first column R1 and the second light source 1200 belonging to the second column R2 can be emitted through the first emission portion 2112 and the second emission portion 2122 forming a single column, thereby achieving a slim appearance design. Furthermore, due to the high light concentration of the first incident portion 2111 and the second incident portion 2121 having a total internal reflection (TIR) ​​structure, light efficiency can be improved.

[0086] In other words, although the TIR structure has high light concentration, it is difficult to achieve a thin design due to its relatively large size. However, in the embodiments of the present invention, since the light incident on the first incident part 2111 and the second incident part 2121 is emitted through the first emission part 2112 and the second emission part 2122 forming a single column by the primary reflection surfaces 2113a, 2123a and the secondary reflection surfaces 2113b, 2123b, the result is that not only can the light efficiency be improved due to the high light concentration, but a thin appearance design can also be achieved.

[0087] As described above, light incident on the incident portions 2111, 2121 of each of the plurality of guide modules 2100 is transmitted by the transmission portions 2113, 2123 to the emission portions 2112, 2122 which are spaced apart from the incident portions 2111, 2121 in the vertical direction and then emitted. Since the emission portions 2112, 2122 of each of the plurality of guide modules 2100, 2110, 2120 form a single column, a slim appearance design can be achieved.

[0088] At this time, as Figure 9 As shown, optical patterns 2131 and 2132 can be formed in at least one emission portion 2112 and 2122 of the plurality of guide modules 2100, and are used to control, for example Figure 6 The shape of at least one of the multiple patterned regions PA shown.

[0089] For example, in the emission section of one of the multiple guide modules 2100, the optical pattern 2131 can be formed to extend in the vertical direction and can be arranged in the horizontal direction. In this case, the size of at least one pattern region in the multiple pattern regions PA in the left-right direction can be controlled.

[0090] Furthermore, in the emission section of another of the plurality of guide modules 2100, the optical pattern 2132 can be formed to extend in the horizontal direction and can be arranged in the vertical direction. In this case, the size of at least one pattern region in the plurality of pattern regions PA in the vertical direction can be controlled.

[0091] In other words, if the direction in which any one of the multiple guide modules 2100 forms an optical pattern 2131 is different from the direction in which another guide module 2100 forms an optical pattern 2132, the dimensions of the different directions of the corresponding pattern regions in the multiple pattern regions can be controlled, thereby forming an optimal beam pattern.

[0092] In an embodiment of the present invention, an example is given where the optical pattern formed in the emission portion of any one of the plurality of guide modules 2100 has a different formation direction from the optical pattern formed in the other emission portion. However, the present invention is not limited thereto. Depending on the light distribution characteristics of each of the plurality of pattern regions PA formed in the vehicle lamp 1 of the present invention, the direction in which at least one of the plurality of guide modules 2100 forms an optical pattern can be varied.

[0093] In addition, such as Figure 10 As shown, the first lens section 2000 may further include an additional reflective section 2200, which reflects light L3 emitted from at least one of the plurality of guide modules 2100, causing a portion of it to travel in a forward direction, and is formed to extend forward from the lower part of the emission sections 2112, 2122 of the plurality of guide modules 2100 of the additional reflective section 2200.

[0094] That is, the additional reflective part 2200 can reflect light emitted from at least one of the first emission part 2112 and the second emission part 2122 so that a portion of the light is reflected in the forward direction, such as... Figure 11 As shown, the light reflected by the additional reflector 2200 can form an extended region E that causes the upper end of the far beam pattern P to extend upward.

[0095] In other words, each of the multiple pattern regions PA of the high beam pattern P can be composed of a basic region B and an extended region E, wherein the basic region B is formed by light emitted from the first emission section 2112 and the second emission section 2122 and directly incident on the second lens section 3000, and the extended region E is formed by light reflected by the additional reflector 2200, thereby improving the field of vision distance in front of the vehicle.

[0096] In an embodiment of the present invention, the case in which the curvature of the additional reflective portion 2200 gradually increases as it moves toward the front end is described as an example. However, this is only an example to help understand the present invention, and the present invention is not limited thereto. Depending on the path of the light reflected by the additional reflective portion 2200, the additional reflective portion 2200 may be formed to have the same curvature as a whole, and one part and another part of the additional reflective portion 2200 may also be formed to have different curvatures from each other.

[0097] like Figure 12 As shown, the vehicle lamp 1 according to the present invention can be configured such that at least one of the plurality of guide modules 2100 is tilted at a predetermined angle with reference to the reference line G parallel to the optical axis Ax of the second lens portion 3000.

[0098] That is, a guide module located close to the optical axis Ax of the second lens section 3000 among the multiple guide modules 2100 can be configured such that the central axis C12 of the emission section is parallel to the reference line G. However, a guide module located relatively far from the optical axis Ax of the second lens section 3000 among the multiple guide modules 2100 can have its central axis C12 tilted at a predetermined angle with reference line G in the direction close to the optical axis Ax of the second lens section 3000. This is to prevent light loss caused by light emitted from a guide module farther from the optical axis Ax of the second lens section 3000 failing to enter the second lens section 3000. Depending on the size of the second lens section 3000 or the position of each of the multiple guide modules 2100, the direction and angle of the tilt of the central axis of the emission section of each of the multiple guide modules 2100 can be varied with reference line G.

[0099] exist Figure 12 In this paper, the central axis C12 of the first ejection portion 2112 of the first guide module 2110 among the multiple guide modules 2100 is used as an example. However, this is only for the purpose of understanding the present invention. The present invention is not limited thereto. The central axis C22 of the second ejection portion 2122 of the second guide module 2120 can also be applied similarly.

[0100] At this time, Figure 12 In order to ensure that the light emitted from the plurality of guide modules 2100 enters the second lens section 3000 with as little loss as possible, the example described is that at least one of the emission portions of the plurality of guide modules 2100 is tilted at a predetermined angle to the optical axis Ax of the second lens section 3000. However, in addition to this, it is also possible to make at least one of the emission portions of the plurality of guide modules 2100 asymmetrically formed on both sides with the central axis as a reference, so that the light emitted from the plurality of guide modules 2100 enters the second lens section 3000 with as little loss as possible.

[0101] In an embodiment of the present invention, the case in which the emitting portion of at least one of the plurality of guide modules 2100 is formed asymmetrically with respect to the central axis is illustrated by the following example: with respect to the central axis, the curvatures of the two sides are different from each other. This is so that the guide module that is laterally spaced further from the optical axis Ax of the second lens portion 3000 in the plurality of guide modules 2100 will refract the emitted light at a larger angle, so that the light emitted from the guide module that is laterally spaced further from the optical axis Ax of the second lens portion 3000 in the plurality of guide modules 2100 can also enter the second lens portion 3000.

[0102] Furthermore, in the vehicle lamp 1 of the present invention, such as Figure 13 As shown, any one of the multiple guide modules 2100 forms the distance between the light source and the emission part in the front-to-back direction in a different manner from each other.

[0103] That is, with the optical axis Ax of the second lens portion 3000 in the plurality of guide modules 2100 as a reference, the guide module located further to the side can be formed such that the distance between the light source and the emission portion is longer. In the embodiment of the present invention, since the plurality of light sources 1000 are disposed on a common substrate, the increased distance between the plurality of light sources 1000 and the corresponding light sources in the plurality of guide modules 2100 and the emission portion of the guide module can be understood as the emission portion being located relatively in front.

[0104] At this time, among the multiple guide modules 2100, the distance d2 between the light source and the emission part of the guide module located further to the side with reference to the optical axis Ax of the second lens section 3000 is longer than the distance d1 between the light source and the emission part of the guide module located closer to the optical axis Ax of the second lens section 3000. This is because the size of the pattern area formed by the light emitted from the guide module located further to the side with reference to the optical axis Ax of the second lens section 3000 will be relatively smaller. In order to compensate for this, by increasing the distance between the light source and the emission part, the size of the pattern area can be increased so that a pattern area of ​​appropriate size can be formed.

[0105] Figure 14 This is a front view showing the second lens portion according to an embodiment of the present invention. Figure 15 This is a rear view showing the second lens portion according to an embodiment of the present invention.

[0106] Reference Figure 14 and Figure 15 According to an embodiment of the present invention, the second lens portion 3000 can transmit light emitted from the first lens portion 2000 and form as described above. Figure 6 and Figure 11The function of the high beam pattern P shown is illustrated in an embodiment of the present invention, taking the case where an exit surface 3200 with a larger curvature than the incident surface is formed in order to improve the focusing power of the light emitted from the second lens section 3000 as an example. However, it is not limited to this. Depending on the light distribution characteristics of the beam pattern formed by the vehicle lamp 1 of the present invention, the curvature of the incident surface 3100 and the exit surface 3200 of the second lens section 3000 can be modified in various ways.

[0107] In order to allow the light emitted from the first lens section 2000 to enter and exit the second lens section 3000 with as little loss as possible, the following example will be given: the refractive index of the first lens section 2000, i.e., the emission sections 2112 and 2122 of the plurality of guide modules 2100, is larger than that of the second lens section. This is because as the refractive index of the first lens section 2000 increases, the second lens section 3000, which has a relatively thinner design, can be used.

[0108] Furthermore, in embodiments of the present invention, at least one of the incident surface 3100 and the emission surface 3200 of the second lens portion 3000 may be formed such that a portion of its area has a curvature different from that of another portion of its area. However, this is not a limitation. Depending on the light distribution characteristics of the beam pattern formed by the vehicle lamp 1 of the present invention, the curvature of the incident surface 3100 and the emission surface 3200 of the second lens portion 3000 may be varied in various ways.

[0109] The second lens portion 3000 described above can form an incident optical pattern 3110 in at least a portion of the incident surface 3100 and an emitted optical pattern 3210 in at least a portion of the emitted surface 3200.

[0110] In an embodiment of the present invention, the case in which the second lens portion 3000 forms an incident optical pattern 3110 on the entire incident surface 3100 and an emitted optical pattern 3210 in a portion of the emitted surface 3200 will be described as an example. This is because when the emitted surface 3200 forms an emitted optical pattern 3210 on the entire incident surface, the beam pattern formed by the vehicle lamp 1 according to the present invention is difficult to have sufficient brightness.

[0111] At this time, the incident optical pattern 3110 can be formed to extend vertically and be arranged horizontally, and the emitted optical pattern 3210 can be formed to extend horizontally and be arranged vertically. However, this is only an example to help understand the present invention. The present invention is not limited thereto. Depending on the light distribution characteristics required for the beam pattern formed by the vehicle lamp 1 of the present invention, the direction of the incident optical pattern 3110 and the direction of the emitted optical pattern 3210 can be the same or different from each other.

[0112] In an embodiment of the present invention, the incident surface 3100 is formed with an incident optical pattern 3110 as a whole so that the beam pattern formed by the vehicle lamp 1 of the present invention has an appropriate width in the left-right direction, and so that the light emitted from the plurality of guide modules 2100 is mixed to have uniform brightness.

[0113] Furthermore, in an embodiment of the present invention, the emission optical pattern 3210 is formed in a portion of the emission surface 3200 so that the beam pattern formed by the vehicle lamp 1 of the present invention has sufficient brightness to ensure a field of view.

[0114] As described above, the vehicle lamp 1 of the present invention, while using the incident portions 2111 and 2121 with high light concentration, can achieve a slim appearance design by forming the emission portions 2112 and 2122 of each of the plurality of guide modules 2100 into a single row.

[0115] Those skilled in the art to which this invention pertains should understand that this 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 limiting embodiments. The scope of this invention is not limited by the foregoing detailed description, but by the claims. All modifications or variations that can be derived from the meaning, scope, and equivalent concepts of the claims should be interpreted as being included within the scope of this invention.
