[0028] As shown in Figures 1 and 2, an automotive lamp 10 (hereinafter referred to as "lamp") according to the present invention may include a light source 100 and a substrate unit 200 on which the light source is mounted. For example, the light source 100 may be an LED or a laser, and the substrate unit 200 may be a PCB (Printed Circuit Board). However, the types of the light source 100 and the substrate unit 200 are not limited to those described above. Meanwhile, a plurality of light sources 100 may be provided.

[0029] The lamp 10 may further include an optical fiber 300 that provides a path for the light emitted from the light source 100. According to the present invention, the optical fiber 300 may be configured to receive the light emitted from the light source 100, move the light forward by total internal reflection, and then emit the light to the outside. For example, the diameter of the optical fiber 300 may be 0.25 mm to 4.0 mm, but the diameter of the optical fiber 300 is not limited thereto.

[0030] A plurality of optical fibers 300 may be provided in the lamp 10. As an example, Fig. 1 illustrates 14 optical fibers 300 provided in the lamp 10. In this case, according to the present invention, at least some of the plurality of optical fibers 300 may be provided so as to cross each other. Fig. 1 illustrates a state in which adjacent optical fibers among the plurality of optical fibers 300 cross each other. However, unlike this, the plurality of optical fibers 300 may be provided in parallel without crossing each other.

[0032] That is, the optical fibers 300 are thin and long, which not only weakens their durability but also makes it difficult to maintain an aligned state during the manufacturing process. Therefore, according to the present invention, the optical fibers 300 are attached to the film part 400, which can protect the optical fibers 300 from the outside, and as will be described later, can maintain an aligned state of the optical fibers 300 during the manufacturing process of the lamp 10, thereby improving the productivity of the lamp 10.

[0033] 3 to 5, the film unit 400 may include an upper film 410 provided on the upper side of the optical fiber 300 and a lower film 420 provided on the lower side of the optical fiber 300. Therefore, at least a portion of the optical fiber 300 may be provided between the upper film 410 and the lower film 420.

[0034] In addition, the optical fiber 300 can be bonded to the upper film 410 and the lower film 420, respectively, and can also be bonded to each other between the upper film 410 and the lower film 420. Therefore, the optical fiber 300, the upper film 410, and the lower film 420 can be fixed in a bonded state relative to each other.

[0035] 1 and 3, the lamp 10 may further include a bezel 500 to which the film 400 is fixed. The bezel 500 is configured to support the film 400, thereby protecting the film 400 and the optical fiber 300 from the outside, and may be configured to ensure the overall rigidity of the lamp 10.

[0036] 3 and 4, the lamp 10 according to an embodiment of the present invention may further include a penetrating member 600 that penetrates the film unit 400.

The penetrating member 600 may have various types of structures, such as a hook structure or a screw structure.

[0037] Meanwhile, referring to FIG. 5, in a lamp 10 according to another example of the present invention, a bezel part 500 may have a recessed portion 510 formed therein, and the film part 400 may be inserted into the recessed portion 510.

[0038] More specifically, the bezel unit 500 may include an upper bezel 520 provided on the upper side of the film unit 400 and a lower bezel 530 provided on the lower side of the film unit 400. In addition, indentations 510 may be formed in the upper bezel 520 and the lower bezel 530 in areas where the upper bezel 520 and the lower bezel 530 face each other, and the film unit 400 may be inserted into the indentations formed in the upper bezel 520 and the lower bezel 530. Thus, according to another embodiment of the present invention, the film unit 400 may be fixed to the bezel unit 500 by the indentations 510. To further improve the fixing strength, the upper bezel 520 and the lower bezel 530 may be joined to each other.

[0039] 1, 2, and 6, the lamp 10 according to the present invention may further include a lens unit 700 provided between the light source 100 and the optical fiber 300 to receive the light emitted from the light source 100, and a first bracket 800 provided between the lens unit 700 and the optical fiber 300. In this case, as shown in FIG. 6, the first bracket 800 may be provided in close contact with the substrate unit 200. The light emitted from the light source 100 and incident on the lens unit 700 may then be emitted from the lens unit 700 and incident on the optical fiber 300. In addition, the first bracket 800 may be configured to fix the lens unit 700 and also to fix a second bracket 900, as described below.

[0040] 6, an internal space may be formed between the substrate unit 200 and the first bracket 800, and the lens unit 700 may be provided in the internal space. More preferably, the first bracket 800 may be configured to press the lens unit 700 toward the substrate unit 200. Therefore, according to the present invention, the lens unit 700 provided in the lamp 10 is fixed to the substrate unit 200 and the first bracket 800, so that the alignment between the light source 100 and the lens unit 700 can be maintained.

[0041] 1, 2 and 6, the lamp 10 according to the present invention may further include a second bracket 900 that is provided between the first bracket 800 and the optical fiber 300 and into which the optical fiber 300 is insert-coupled. In this case, the second bracket 900 may be insert-coupled to the first bracket 800. Therefore, according to the present invention, the alignment of the light source 100, the lens unit 700, the first bracket 800, the second bracket 900 and the optical fiber 300 may be maintained.

[0042] Meanwhile, as described above, the upper film 410 and the lower film 420 may be bonded to each other, but in this case, the upper film 410 and the lower film 420 may be made of different materials. Also, the upper film 410 and the lower film 420 may each be made of any one material selected from the group consisting of TPU (Thermoplastic Polyurethane), PETG (Poly Ethylene Terephthalate Glycol), and PVC (Poly Vinyl Chloride).
