The above objects, features and effects of the present disclosure can be understood by the exemplary embodiments with reference to the accompanying drawings. However, the present disclosure is not limited to the exemplary embodiments described herein, and may also be applied and modified in various forms. Rather, exemplary embodiments of the present disclosure, which will be described later, are provided to further clarify the technical spirit of the present disclosure and to further fully convey the technical spirit of the present disclosure to those skilled in the art to which the present disclosure pertains. Therefore, the scope of the present disclosure should be construed as not being limited by the exemplary embodiments described later. Meanwhile, in the following exemplary embodiments and the accompanying drawings, like reference numerals denote like parts.

In addition, terms such as "first" and "second" in the present specification have no limiting meaning and are used for the purpose of distinguishing one component from another component. Further, when a portion such as a film, a region, or a member is referred to as being "over" or "on" another portion, this includes not only a case where the portion is directly on the other portion but also a case where another film, a region, a member, or the like is interposed between the portions.

Referring to fig. 1, two rear combination lamps RCL1, RCL2 are mounted on both sides of the rear portion of a vehicle 500. Two rear combination lamps RCL1, RCL2 are installed in the vehicle 500 having a rear door at the rear of the main body BD. In the present exemplary embodiment, two rear combination lamps RCL1, RCL2 may be mounted in the vehicle 500 in which the trunk door TK is mounted on the main body BD.

In the present exemplary embodiment, the two rear combination lamps RCL1, RCL2 may have a structure in which the two rear combination lamps RCL1, RCL2 are installed at different positions in the vehicle 500 but correspond to each other. Therefore, the structure of one rear combination lamp RCL1 of the two rear combination lamps RCL1, RCL2 installed at the rear left side of the main body BD will be described below, and the description of the structure of the other rear combination lamp RCL2 installed at the rear right side of the main body BD will be omitted.

Rear combination lamp RCL1 includes a first rear lamp module 100 and a second rear lamp module 300. The first rear lamp module 100 is mounted on a side portion of the rear of the main body BD to output information related to the travel of the vehicle 500 as light rearward from the vehicle 500, thereby providing the information to a driver of a following vehicle.

In the present exemplary embodiment, the entire illumination region of the first rear lamp module 100 includes a first main illumination region 101, a second main illumination region 102, a third main illumination region 103, and a fourth main illumination region 104.

In the present exemplary embodiment, when the first main illumination region 101 is illuminated, the position of the rear of the vehicle 500 may be notified to the driver of the vehicle behind; when the second main illumination zone 102 is illuminated, the brake of the vehicle 500 may be notified to the driver of the following vehicle; when the third main illumination region 103 is illuminated, the driver of the following vehicle may be informed of the steering of the vehicle 500; and when the fourth main illumination zone 104 is illuminated, the driver of the following vehicle may be informed of the reversing of the vehicle 500.

As described above, in the present exemplary embodiment, the entire illumination area of the first rear lamp module 100 includes the first to fourth main illumination areas 101, 102, 103, 104 informing the above-described specific information, but the present disclosure is not limited to the configuration of the illumination area of the first rear lamp module 100. For example, in another exemplary embodiment, a plurality of first main illumination regions 101 may be provided such that the plurality of first main illumination regions may be integrally driven together with each other. And in still another exemplary embodiment, the second main illumination region 102 may be divided into two illumination regions, and the two illumination regions are driven independently of each other to inform the driver of the following vehicle of different traveling information of the vehicle 500.

In the present exemplary embodiment, the second rear light module 300 includes a first sub illumination region 301, a second sub illumination region 302, and a third sub illumination region 303. In the present exemplary embodiment, the first sub illumination region 301 may be integrally driven together with the first main illumination region 101, and the first sub illumination region 301 may inform the driver of the vehicle in the rear of the vehicle 500 of the position. The second sub illumination region 302 may be integrally driven together with the second main illumination region 102, and the second sub illumination region 302 may inform a driver of the following vehicle of the braking of the vehicle 500. The third sub illumination region 303 may be integrally driven together with the third main illumination region 103, and the third sub illumination region 303 may inform the driver of the following vehicle of the steering of the vehicle 500.

The first rear lamp module 100 includes a light source as a component, and illuminates in a self-luminous manner. However, the second rear lamp module 300 does not include a light source as a component, and the second rear lamp module 300 receives light from the light source provided in the first rear lamp module 100 and illuminates in a non-self-luminous manner. Therefore, a power supply line for supplying power to rear combination lamp RCL1 composed of first rear lamp module 100 and second rear lamp module 300 is mounted on main body BD of vehicle 500 in which first rear lamp module 100 is located. The installation of a power line on the TK of the backup box door can be omitted.

Hereinafter, the structures of the first and second rear lamp modules 100 and 300 will be described in more detail with reference to fig. 2 and 3.

Referring to fig. 2 and 3, the first rear lamp module 100 includes a first receiving unit 120, a plurality of partition walls 121, a first main light source LS1, a second main light source LS2, a third main light source LS3, a fourth main light source LS4, sub light source LEDs, and a first cover unit C1.

The first accommodating unit 120 accommodates the first to fourth main light sources LS1, LS2, LS3, LS 4. Further, the inner surface of the first receiving unit 120 is coated with a reflective layer, and light emitted from the first to fourth main light sources LS1, LS2, LS3, LS4 may be reflected to the front of the first rear lamp module 100. Therefore, the amount of light output through the first to fourth main illumination regions 101, 102, 103, 104 can be increased.

Each of the plurality of partition walls 121 extends substantially vertically from the bottom of the first receiving unit 120. Accordingly, the internal space of the first receiving unit 120 may be partitioned into a plurality of internal spaces by the plurality of partition walls 121. In the present exemplary embodiment, the plurality of partition walls 121 may be made of a material that reflects light, such as a white mold, so as to prevent light from being mixed with each other in the plurality of inner spaces of the first receiving unit 120 partitioned by the plurality of partition walls 121, to clarify shapes illuminated in the first to fourth main illumination areas 101, 102, 103, 104.

The first to fourth main light sources LS1, LS2, LS3, LS4 are arranged to have a one-to-one correspondence with the first to fourth main lighting regions 101, 102, 103, 104. The first rear light module 100 is lighted using light emitted from the first to fourth main light sources LS1, LS2, LS3, LS4, and a light emitting surface of each of the first to fourth main light sources LS1, LS2, LS3, LS4 may be oriented toward the front of the first rear light module 100.

In the present exemplary embodiment, the first to fourth main light sources LS1, LS2, LS3, LS4 receive electricity through different power lines, and thus, the first to fourth main light sources LS1, LS2, LS3, LS4 may be lighted independently of each other. Further, power supply lines electrically connected to each of the first to fourth main light sources LS1, LS2, LS3, LS4 may be drawn to the outside through-holes defined in the first receiving unit 120 to be electrically connected to an external power supply device.

For example, the first main light source LS1 may be electrically connected to the first power supply line PL 1; the first power supply line PL1 may be drawn out to the outside through a through-hole formed in the first accommodation unit 120; and the first power supply line PL1 drawn out to the outside may be electrically connected to power supply equipment installed in the vehicle, such as a battery and a generator.

The light emitting surface of each sub light source LED faces the second rear lamp module 300, and the sub light source LEDs provide light to the second rear lamp module 300. The sub light source LED is a component provided in the first rear lamp module 100, but the light provided by the sub light source LED is not used to illuminate the first rear lamp module 100, and the light provided by the sub light source LED is used to illuminate the second rear lamp module 300.

In the present exemplary embodiment, the sub light source LED may be fixed to one side portion 122 of the first receiving unit 120 adjacent to the second rear lamp module 300. More specifically, a circuit board PCB may be coupled to the side portion 122 of the first receiving unit 120, and the sub light source LEDs may be mounted on the circuit board PCB.

In the present exemplary embodiment, the second power line PL2 may be electrically connected to a connector (not shown) of the circuit board PCB; the second power supply line PL2 may be drawn out to the outside of the first accommodation unit 120 through a through-hole defined in the first accommodation unit 120; and the second power line PL2 drawn to the outside may be electrically connected to the power supply apparatus. Therefore, the driving of the sub light source LEDs may be performed independently of the driving of the first to fourth main light sources LS1, LS2, LS3, LS 4.

Further, in the present exemplary embodiment, the sub light source LEDs are divided into a plurality of groups, and driving of the sub light source LEDs divided into the plurality of groups may be controlled by a driver (not shown) mounted on a PCB on a circuit board. Therefore, the first to third sub illumination regions 301, 302, 303 may be illuminated independently of each other. For example, in the case of selectively driving only two sub light sources arranged on top of the total of seven sub light source LEDs shown in fig. 2, the first sub lighting region 301 is illuminated, and the second and third sub lighting regions 302 and 303 may not be illuminated.

The first cover unit C1 is coupled to the first containing unit 120 to cover the first to fourth main light sources LS1, LS2, LS3, LS 4. The first cover unit C1 may be made of a material having light transmittance, for example, the first cover unit C1 may be made of Polymethylmethacrylate (PMMA) or Polycarbonate (PC). Accordingly, light emitted from the first to fourth main light sources LS1, LS2, LS3, LS4 may be emitted to the outside through the first cover unit C1.

In another exemplary embodiment, the first cover unit C1 may include an auxiliary cover unit (not shown) covering the sub light source LEDs. In this case, the auxiliary cover unit may have a reflective surface covering the sub light source LED, so that light generated by the sub light source LED is prevented from leaking to the outside through a gap between the first rear lamp module 100 and the second rear lamp module 300 by the auxiliary cover unit.

The second rear lamp module 300 includes a second receiving unit 130, a first partition wall 131, a second partition wall 132, a light receiving unit 200, a light direction changing unit 250, and a second cover unit C2.

In the present exemplary embodiment, the second accommodation unit 130 accommodates the light-direction changing unit 250, and each of the first and second partition walls 131 and 132 extends substantially vertically from the bottom of the second accommodation unit 130. Specifically, the first partition wall 131 is located at an interface between the first sub lighting region 301 and the second sub lighting region 302, and the second partition wall 132 is located at an interface between the second sub lighting region 302 and the third sub lighting region 303.

The inner space of the second receiving unit 130 may be partitioned into a plurality of inner spaces by the first and second partition walls 131 and 132. Further, the first and second partition walls 131 and 132 are made of a material that reflects light, such as a white mold. Accordingly, it is possible to prevent the lights from being mixed with each other in the inner space of the accommodating unit 130 partitioned by the first and second partition walls 131 and 132, thereby further clarifying the shapes illuminated in the first to third sub lighting regions 301, 302, 303.

The light receiving unit 200 receives light from the sub light sources LED of the first rear lamp module 100. The second rear lamp module 300 outputs light using light received by the light receiving unit 200 from the sub light source LED.

In the present exemplary embodiment, the light receiving unit 200 may include a sidewall SW coupled to a side of the second receiving unit 130 adjacent to the sub light source LED, and may define an opening LD in the sidewall SW through which light passes. When the second rear lamp module 300 is separated from the first rear lamp module 100, the opening LD may have a shape opened to the outside.

In another exemplary embodiment, the light-receiving unit 200 may be further defined by opening the entire portion of the second receiving unit 130 facing and adjacent to the sub light source LED, and in yet another exemplary embodiment, the light-receiving unit 200 may be further defined by forming a portion of the second receiving unit 130 facing and adjacent to the sub light source LED with a material that transmits light.

In the present exemplary embodiment, the light receiving unit 200 may further include a lens plate LP and a lens LS. The lens plate LP may be coupled to the sidewalls SW to face the sub-light sources LED. The lens plate LP may be made of a material having light transmitting properties, for example, the lens plate LP may be made of plastic, glass, or silicone such as Polymethylmethacrylate (PMMA) or Polycarbonate (PC).

The lens LS is disposed on the lens plate LP, and in the present exemplary embodiment, the lens LS is integrally formed with the lens plate LP such that the material of the lens LS may be the same as that of the lens plate LP. In the present exemplary embodiment, each lens LS may condense light provided by the sub light source LED.

When the lens LS disposed on the lens plate LP is defined as a lens array and the sub light source LEDs disposed on the circuit board PCB is defined as a sub light source array, the lens array is located between the sub light source array and the opening LD, and the lens array faces the sub light source array. Therefore, the amount of light leaking to the vicinity of the opening LD can be minimized by the lens LS, thereby increasing the amount of light received through the opening LD.

The light-direction changing unit 250 converts the traveling direction of the light received by the light receiving unit 200 to output the light to the outside. In the present exemplary embodiment, three light direction changing units 250 may be provided to correspond one-to-one to the first sub illumination region 301, the second sub illumination region 302, and the third sub illumination region 303. Although the three light-direction changing units 250 in the second rear lamp module 300 have been arranged at different positions, the three light-direction changing units 250 may have structures corresponding to each other. Therefore, description will be made taking, as an example, the light-direction changing unit 250 arranged at a position corresponding to the first sub lighting region 301 among the three light-direction changing units 250, and description of the remaining light-direction changing units will be omitted.

The light-direction changing unit 250 includes a light-guiding member LGP, a reflecting member RF, and a diffusing member DF. In the present exemplary embodiment, each of the light guiding member LGP, the reflecting member RF, and the diffusing member DF is illustrated in a plate shape, but in another exemplary embodiment, at least any one of the light guiding member LGP, the reflecting member RF, and the diffusing member DF may also have a sheet shape or a film shape.

Hereinafter, the configuration of the light direction changing unit 250 will be described in more detail as follows with reference to fig. 4.

Further referring to fig. 4, light received by the light receiving unit 200 is provided toward the light direction changing unit 250, and the light direction changing unit 250 changes the traveling direction of the provided light, and the light whose traveling direction is changed by the light direction changing unit 250 is output to the outside through the second cover unit C2.

More specifically, light is incident into the light guiding member LGP through the incident surface S1 of the light guiding member LGP, and the traveling direction of the light incident on the light guiding member LGP is changed by the light guiding pattern LG defined on the rear surface of the light guiding member LGP. Further, the light, the traveling direction of which is changed by the light guide pattern LG, exits to the outside of the light guide member LGP through the exit surface ES of the light guide member LGP.

The reflection member RF has a reflection surface S2 facing the light guide member LGP. The reflecting member RF reflects light leaking through the rear surface of the light guiding member LGP toward the light guiding member LGP. Further, the light reflected by the reflection member RF may be incident on the light guide member LGP again and output to the outside through the first to third sub-lighting regions 301, 302, 303.

The diffusion member DF faces the reflection member RF via the light guide member LGP. The diffusion member DF contains particles that reflect light, such as titanium dioxide, or includes a concave-convex pattern on its surface. Accordingly, the light may be diffused by the diffusion member DF, and thus, the luminance of the light output from each of the first to third sub-lighting regions 301, 302, 303 may be uniform.

In another exemplary embodiment, the light-direction changing unit 250 may further include an optical sheet. For example, the light-direction changing unit 250 may further include a light-condensing sheet having a prism pattern. In this case, a light-condensing sheet may be disposed between the second cover unit C2 and the diffusion member DF to condense light emitted from the diffusion member DF in the front direction, thereby increasing the luminance of each of the first to third sub lighting regions 301, 302, 303 in the front direction by the light-condensing sheet.

A process of changing the path of the light emitted from the sub light source LED by the above-described configuration of the light receiving unit 200 and the light direction changing unit 250 will be described in detail as follows.

The first light L1 is generated from the sub-light source LED. After that, the first light L1 is incident on the lens LS, and the first light L1 is condensed by the lens LS, and thus the second light L2 is defined.

After that, the second light L2 is incident into the light guiding member LGP through the incident surface S1 of the light guiding member LGP. The light incident on the light guiding member LGP is totally reflected inside the light guiding member LGP and thus the third light L3 is defined.

After that, the third light L3 is reflected from the light guiding pattern LG, and its proceeding direction is changed to be emitted to the outside through the exit surface ES of the light guiding member LGP. The third light L3 is diffused by the diffusion member DF and thus may define a fourth light L4.

The second cover unit C2 is coupled to the second receiving unit 130 to cover the light-direction changing unit 250 received in the second receiving unit 130. The second cover unit C2 may be made of the same material as the first cover unit C1 to have light transmittance. Therefore, the light, the traveling direction of which is changed by the light direction changing unit 250, may be emitted to the outside through the second cover unit C2.

Referring to fig. 5, a cross-section of a first rear lamp module 100 and a second rear lamp module 301 of a rear combination lamp RCL1-1 for a vehicle according to another exemplary embodiment of the present disclosure is shown. More specifically, fig. 5 shows a cross-section of a portion of the rear combination lamp RCL1-1 where the first rear lamp module 100 and the second rear lamp module 301 are connected to each other, and a position of the cross-section of the rear combination lamp RCL1-1 shown in fig. 5 may correspond to a position of the cross-section taken along the line I-I' of the rear combination lamp (RCL 1 in fig. 2) shown in fig. 2.

Meanwhile, the rear combination lamp RCL1-1 according to the present exemplary embodiment includes the same components as the above-described rear combination lamp (RCL 1 in fig. 2) except for the configuration of the light receiving unit 201 and the reflecting member RF-1. Therefore, in describing fig. 5, the above-described components are denoted by reference numerals, and repeated description of the components is omitted.

In the present exemplary embodiment, the reflecting member RF-1 has a shape coated on the inner surface of the accommodating unit 130. For example, the inner surface of the accommodating unit 130 may be coated with a material containing particles (such as titanium dioxide) to reflect light to realize the reflecting member RF-1, or the inner surface of the accommodating unit 130 may be coated with a white paint to realize the reflecting member RF-1.

In the present exemplary embodiment, the light receiving unit 201 may include a sidewall coupled to a side of the second receiving unit 130 adjacent to the sub light source LED, and defining an opening LD through which light passes in the light receiving unit 201. That is, when comparing the configuration of the light receiving unit (200 in fig. 3) shown in fig. 3 with the configuration of the light receiving unit 201 shown in fig. 5, the lens plate (LP in fig. 3) and the lens (LS in fig. 3) may be omitted as components of the light receiving unit 201.

Therefore, even if no lens is provided in the light receiving unit 201, the sub light source LEDs are aligned in the opening LD, and when the separation distance between each sub light source LED and the light receiving unit 201 is adjusted in consideration of the beam angle of the light output from each sub light source LED, the amount of light leaking to the outside during the movement of the light from the sub light source LED to the light receiving unit 201 can be minimized.

As described above, although the present disclosure has been described with reference to the exemplary embodiments, it will be understood by those skilled in the art that various modifications and changes may be made to the present disclosure without departing from the spirit and scope of the present disclosure described in the scope of the appended claims.
