Specific details for implementing the invention

[0022] Hereinafter, a vehicle lamp module and a vehicle lamp according to the present invention will be described with reference to the drawings.

[0024] Vehicle lamp module

[0026] FIG. 1 is a vertical cross-sectional view of a vehicle lamp module according to the present invention, and FIG. 2 is a perspective view of a vehicle lamp module according to the present invention. FIG. 3 is a horizontal cross-sectional view of a first example of a vehicle lamp module according to the present invention, and FIG. 4 is an enlarged view of a part of the lens member of FIG. 3. FIG. 5 is a horizontal cross-sectional view of a second example of a vehicle lamp module according to the present invention, and FIG. 6 is an enlarged view of a part of the lens member of FIG. 5.

[0028] Referring to FIGS. 1 and 2, a vehicle lamp module (100, hereinafter referred to as "lamp module") according to the present invention may include a light source (110) that emits light and a bezel member (120) that accommodates the light source inside. The bezel member (120) may be configured to form a space that accommodates the light source (110) while allowing the lamp module (100) to be fixed to another part of the vehicle.

[0029] Additionally, the lamp module (100) may further include a lens member (130) fixed to the front of the bezel member (120). The lens member (130) according to the present invention may be a micro-cylinder lens. It may be configured to have a structure in which a plurality of micro-cylinder lenses are arranged in one direction. That is, the lens member (130) may include a plurality of cylinder lens units (132) that extend in the vertical direction (H) of the lamp module (100) and are arranged in the horizontal direction (W). The width of the cylinder lens units (132) provided in the lens member (130) may be within the range of tens of micrometers to hundreds of micrometers.

[0031] FIG. 3 is a horizontal cross-sectional view of a first example of a vehicle lamp module according to the present invention, and FIG. 4 is an enlarged view of a part of the lens member of FIG. 3. FIG. 5 is a horizontal cross-sectional view of a second example of a vehicle lamp module according to the present invention, and FIG. 6 is an enlarged view of a part of the lens member of FIG. 5.

[0032] Referring to FIGS. 3 to 6, a plurality of cylinder lens units (132) provided in a lens member (130) may include a cylinder incident surface (132a) into which a light source (110) is incident and a cylinder exit surface (132b) spaced forward from the cylinder incident surface (132a). The cylinder incident surface (132a) and the cylinder exit surface (132b) may each have a convex or concave columnar shape.

[0034] As illustrated in FIGS. 3 and 4, according to one example of the present invention, the shapes of the horizontal cross-sections of the plurality of cylindrical incident surfaces (132a) provided in the plurality of cylindrical lens units (132) may correspond to each other or be substantially identical.

[0035] On the other hand, as illustrated in FIGS. 5 and 6, according to another example of the present invention, the shape of the horizontal cross-section of the cylinder incident surface (132a) of some of the plurality of cylinder lens units (132) may be different from the shape of the horizontal cross-section of the cylinder incident surface (132a) of some of the plurality of cylinder lens units (132).

[0036] More specifically, as illustrated in FIGS. 5 and 6, according to another example of the present invention, at least some of the cylinder incident surfaces (132a) of a plurality of cylinder lens units (132) within a lens member (130) may have a concave lens shape. More preferably, each cylinder incident surface (132a) provided in a plurality of cylinder lens units (132) may have a concave lens shape. However, unlike the above, some of the cylinder incident surfaces (132a) of the plurality of cylinder lens units (132) may have a concave lens shape, while other cylinder incident surfaces (132a) of the plurality of cylinder lens units (132) may have a convex lens shape.

[0038] Meanwhile, as shown in FIGS. 1 and 2, an open hole (120a) is formed in the front region of the bezel member (120), and the lens member (130) may have a structure inserted into the open hole (120a).

[0039] For example, the bezel member (120) and the lens member (130) may be formed integrally. In this case, the bezel member (120) and the lens member (130) may have different materials or colors. In this case, the bezel member (120) and the lens member (130) may be manufactured together by a double injection molding method.

[0041] Meanwhile, according to one example of the present invention, the bezel member (120) may include an opaque material, and the lens member (130) may include a transparent material. This may be intended to prevent light from reaching unwanted areas by ensuring that light emitted from the light source (110) is emitted to the outside through the lens member (130) but not emitted to the outside through the bezel member (120).

[0043] On the other hand, unlike the above description, the bezel member (120) and the lens member (130) may each include a light-transmitting material. In this case, the lamp module (100) may further include a light-shielding layer (not shown) provided on the outer or inner surface of the bezel member (120). The light-shielding layer can prevent light from being emitted to the outside through the bezel member (120) having the light-transmitting material.

[0045] Below, the detailed shape of the bezel member (120) is described.

[0046] Referring again to FIGS. 1 and FIGS. 2, the bezel member (120) may include an upper surface area (122) that forms the upper surface of the bezel member (120) and extends in the front-rear direction (A), a lower surface area (124) that forms the lower surface of the bezel member (120) and extends in the front-rear direction (A), and a front connecting area (126) that connects the upper surface area (122) and the lower surface area (124) and forms an open hole (120a). Accordingly, the lens member (130) may be fixed to the lens member (130) in a form inserted into the open hole (120a).

[0047] Additionally, as an example, the bezel member (120) may have a shape in which the vertical width (H) between the upper surface area (122) and the lower surface area (124) decreases as it moves forward.

[0049] Meanwhile, according to the present invention, the left-right direction (W) thickness of the portions provided on the left and right sides of the open hole (120a) among the portions surrounding the open hole (120a) in the front connection area (126) may be thinner than the up-down direction (H) thickness of the portions provided on the upper and lower sides of the open hole (120a) among the portions surrounding the open hole (120a) in the front connection area (126). As described below, the lamp module (100) according to the present invention may have a structure in which a plurality of them are arranged in the left-right direction (W). As described above, when the left-right direction (W) thickness of the portions provided on the left and right sides of the front connection area (126) is relatively thin, the connectivity of the light-emitting surfaces formed by the two lamp modules (100) that are provided adjacent to each other in the left-right direction (W) may be improved.

[0050] On the other hand, unlike the above, the front connection area (126) is provided to surround the upper and lower parts of the opening hole (120a), and the opening hole (120a) may be open in the left and right directions. This can be understood as the front connection area (126) being formed only on the upper and lower parts of the opening hole (120a). In this case, when viewing the lamp module from the front, the proportion of the part occupied by the lens member (130) in the left and right directions may be increased. Therefore, as described later, when the lamp modules are arranged in multiple left and right directions, the connectivity of the light-emitting surface formed by each lamp module may be further improved.

[0052] Vehicle lamps

[0054] According to the present invention, a vehicle lamp (10) may include a plurality of lamp modules (100), and the plurality of lamp modules (100) may be arranged in a left-right direction (W). The description of the lamp module (100) provided in the vehicle lamp (10) according to the present invention is replaced by the description of the lamp module according to the present invention as described above with reference to FIGS. 1 to 6.

[0055] Meanwhile, in the vehicle lamp (10) according to the present invention, the bezel members (120) provided on two vehicle lamp modules (100) adjacent to each other in the left-right direction (W) may be provided to be in contact with each other. In this case, the connectivity of the light-emitting surface formed by each lamp module (100) may be improved.

[0057] Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto, and it is obvious that various implementations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the claims described below by those skilled in the art to which the present invention belongs.
