Moreover, when the optical assembly 10 includes the light-shielding portion 425 as shown in FIG. 10, the light-shielding portion 425 is disposed in a region that does not overlap in the vertical direction (V-axis direction) with the opening region 710 of the blocking member 700 and can overlap in the vertical direction with the non-transmissive region 720.

At this time, the lighting module 400 according to the embodiment is arranged to be inclined. Specifically, It can include a radar, a laser, a sound wave, a video sensor, etc., and is arranged behind and / or beside the vehicle.

[0153] At this time, the lighting module 400 according to the embodiment is arranged to be inclined. Specifically, , the upper surface of the optical assembly 10 can be in contact with the blocking member 700, and the upper surface of the blocking member 700 can be in contact with the bottom surface 821 of the mirror member 820.

[0154] Thereby, the illumination module 400 of the optical assembly 10 is arranged to be inclined with respect to the bottom surface 82 1 of the mirror member 820. Specifically, with respect to the direction of the second inner surface IS2 on the first inner surface IS1, the illumination module 400 can be inclined at the first inclination angle A1. Also, with respect to the direction of the fourth inner surface IS4 on the third inner surface IS3, the illumination module 400 can be inclined at the second inclination angle a2 . That is, the illumination module 400 can be inclined in the direction of the fifth inner surface IS5 at the first intersection point P1 of the housing 300. More specifically, the bottom surface 310 of the housing 300 can be inclined as described above, and the illumination module 400 and the optical member 500 disposed on the bottom surface 310 can have an inclined form at the inclination angles within the above-described range . . The bottom surface 310 of the housing 300 can be inclined as described above, and the illumination module disposed on the bottom surface 310 400 and the optical member 500 can have an inclined form at the inclination angles within the above-described range.

[0155] Thereby, the rear view mirror assembly 2000 according to the embodiment can minimize light loss and maximize the amount of light emitted through the mirror member 820, and can control the emission direction of the emitted light and the luminance value of the light corresponding to the emission direction.

[0156] FIG. 18 is a drawing for explaining the emission angle of the light emitted from the rear view mirror assembly according to the embodiment. In the description of FIG. 18, it will be described with respect to the one applied to the left side mirror adjacent to the driver's seat. In the case of the right side mirror adjacent to the passenger seat, the description will be made with respect to the one applied to the left side mirror adjacent to the driver's seat. In the case of the right side mirror adjacent to the passenger seat, the Since the configurations including the optical assembly 10 are symmetric with the same shape to each other, for convenience of explanation, the left side The structure applied to the driver's side mirror will be mainly described.

[0157] Referring to FIG. 18, the rear view mirror assembly 2000 according to the embodiment can provide vehicle information located at the rear side to the driver. For example, in a region overlapping with the optical assembly 10, it can be divided into a first region R1 and a second region R2 with reference to a virtual line L1 extending in a direction perpendicular to the extension direction of the rear view mirror assembly 2000. Here, the first region R1 is the region where the driver 1 is located, and the second region R2 is the region where another vehicle 2 or an object is located at the rear side of the vehicle in which the driver 1 is riding. It may be.

[0158] When another vehicle 2 is located in the second region R2 of the rear view mirror assembly 2000 according to the embodiment, the light emitted from the optical assembly 10 is emitted to the outside through the blocking member 700 and the mirror member 820.

[0159] At this time, the lighting module 400 is arranged to be inclined with respect to the bottom surface 310 of the mirror member 820 as described above. For example, the lighting module 400 is arranged to be inclined in a direction corresponding to the first region R1 where the driver 1 is located. Therefore, the light emitted from the rear view mirror assembly 2000 through the mirror member 820 is emitted in a set direction and can have different luminance values depending on the emission direction.

[0160] For example, the luminance value of the light emitted in the direction of the first region R1 where the driver 1 is located is The luminance value of the light emitted in the direction of the second region R2 where the other vehicle 2 is located may be different. . Specifically, the luminance value of the light emitted in the direction of the first region R1 may be greater than the luminance value of the light emitted in the direction of the second region R2.

[0161] Thus, the rear view mirror assembly 2000 according to the embodiment can provide high-luminance light to the driver 1 located in the first region R1. Also, the rear view mirror assembly 2000 can provide relatively low-luminance light to the other vehicle 2 located on the rear side of the driver 1's vehicle in the second region R2.

[0162] Therefore, the driver 1 can effectively visually recognize the shape of the indicator unit 850. Also, the light emitted from the rear view mirror assembly 2000 in the direction of the other vehicle 2 located on the rear side of the driver 1 can be minimized. Therefore, it is possible to minimize or prevent the driver of the other vehicle 2 from being obstructed in driving by the light.
