[0013] 3, the cover 5 and the outer frame 6 are assembled so as to fit together in the front-to-rear direction, and are arranged so as to define an installation space capable of accommodating the first light-emitting unit 1, the second light-emitting unit 2, and the heat dissipation unit 4. That is, the first light-emitting unit 1, the second light-emitting unit 2, the mounting frame 3, and the heat dissipation unit 4 are sandwiched between the cover 5 and the outer frame 6 and positioned in the above-mentioned installation space. Here, the specific configuration of the cover 5 and the outer frame 6 is not a feature of the present invention, and therefore, even without further detailed description thereof, it is believed that a person skilled in the art can understand it based on the contents of the present invention.

[0014] Hereinafter, configurations of the first light-emitting unit 1 and the second light-emitting unit 2 of the vehicle lamp device according to the present invention will be described with reference to the drawings.

[0015] The configurations of the first light-emitting unit 1 and the second light-emitting unit 2 of the vehicle lamp device according to the present invention will be described with reference to Fig. 4 to Fig. 8. Here, Fig. 4 is a side cross-sectional view showing the configurations of the first light-emitting unit 1, the second light-emitting unit 2, the mounting frame 3, and the heat dissipation unit 4 in the vehicle lamp device according to the embodiment, and Fig. 5 is an exploded perspective view showing the configurations of the first light-emitting unit 1, the second light-emitting unit 2, the mounting frame 3, and the heat dissipation unit 4 in the vehicle lamp device according to the embodiment. In addition, Figure 6 is an oblique view showing the configuration of the first lens module 11 and the second lens module 21 of the vehicle lamp device according to the embodiment, Figure 7 is a top cross-sectional view showing the configuration of the first light-emitting unit 1 of the vehicle lamp device according to the embodiment, and Figure 8 is a top cross-sectional view showing the configuration of the second light-emitting unit 2 of the vehicle lamp device according to the embodiment.

[0016] As shown in Figures 4 to 6, the first light-emitting unit 1 has a first lens module 11 that is arranged to be fitted into the mounting frame 3, and a first light-emitting module 12 that is arranged to be connected to the heat dissipation unit 4 on the rear side of the first lens module 11.

[0017] The first lens module 11 has a plurality of first lenses 111 arranged in a predetermined first shape as shown in Fig. 5. In this embodiment, the first shape is an F-shape as shown in Fig. 2 and Fig. 5, but is not limited thereto and may be changed according to needs in other embodiments.

[0018] As shown in FIG. 5, the first light emitting module 12 has a plurality of first light sources 121 arranged behind a plurality of first lenses 111, respectively.

[0019] In this embodiment, four first lenses 111 and four first light sources 121 are provided, as shown in Fig. 5. The numbers of first lenses 111 and first light sources 121 are not limited to those described above, and may be changed in other embodiments.

[0020] As shown in FIGS. 4 to 6, each first lens 111 is divided into a first light condenser section 112, a first light guide section 113, and a first lens section 114 in that order from the rear side to the front side.

[0021] The first light collecting section 112 can collect the light emitted by the corresponding first light source 121 in a forward direction.

[0022] 4, the first light guide section 113 is located between the first light collecting section 112 and the first lens section 114 and can guide the light collected by the first light collecting section 112 toward the first lens section 114. The first light guide sections 113 of adjacent first lenses 111 communicate with each other.

[0023] The first lens section 114 allows the light collected by the first light collecting section 112 to transmit in the forward direction.

[0024] 4 to 6, a plurality of first lens portions 115 are formed in the first lens section 114 of each first lens 111, and are arranged in at least one row along the horizontal direction. In this embodiment, the number of rows of the plurality of first lens portions 115 is multiple, that is, a plurality of rows of the first lens portions 115 arranged in the vertical direction are formed in each first lens section 114. In addition, the degree of protrusion of each first lens portion 115 in the forward direction differs, and the lens curvature of each first lens portion 115 measured in the left-right direction differs from the lens curvature of each first lens portion 115 measured in the vertical direction.

[0025] As shown in Figures 4 to 6, two adjacent first lens portions 115 are arranged in the vertical direction, and are configured so that the bottom of the upper first lens portion 115 protrudes forward relative to the top of the other first lens portion 115 below, creating a step 116.

[0026] Each first lens portion 115 can cause light transmitted in a forward direction to become a first light pattern.

[0027] In this embodiment, the first light guide sections 113 of adjacent first lenses 111 communicate with each other, so that the light that enters the first light guide section 113 of each first lens 111 can not only transmit forward through the corresponding first lens section 114 on the front side, but also travel to another adjacent first light guide section 113 and transmit forward through the corresponding first lens section 114. Of course, this is not limited thereto, and in other embodiments, as long as the light refracted and transmitted forward by the first lens portion 115 of each first lens 111 can be projected to form the first light pattern, the first light guide sections 113 of adjacent first lenses 111 do not need to communicate with each other.

[0028] Furthermore, in other embodiments, the first light guide section 113 may not be required in each first lens 111, as long as the light collected by the first light collecting section 112 can reach the corresponding first lens section 114 and be refracted and transmitted in the forward direction.

[0029] As shown in Figures 4 to 6, the second light-emitting unit 2 has a second lens module 21 that is arranged to be fitted into the mounting frame 3, and a second light-emitting module 22 that is arranged to be connected to the heat dissipation unit 4 on the rear side of the second lens module 21.

[0030] As shown in FIG. 5, the second lens module 21 has a plurality of second lenses 211 that are connected together in the vertical direction and arranged in a predetermined second shape together with the plurality of first lenses 111 in the first lens module 11. In this embodiment, the second shape is an F-shape larger than the first shape as shown in Figures 2 and 5, but is not limited thereto and may be changed according to needs in other embodiments.

[0031] As shown in FIG. 5, the second light emitting module 22 has a plurality of second light sources 221 arranged behind the plurality of second lenses 211, respectively. In this embodiment, three second lenses 211 and three second light sources 221 are provided, as shown in Fig. 5. The numbers of second lenses 211 and second light sources 221 are not limited to those described above, and may be changed in other embodiments.

[0032] 4 to 6, each second lens 211 has a second light collecting section 212 for collecting light emitted from the corresponding second light source 221 in a forward direction, and a second lens section 213 exposed from the mounting frame 3 and through which the light collected by the second light collecting section 212 transmits in a forward direction. The second light collecting sections 212 of adjacent second lenses 211 communicate with each other, and in adjacent first lenses 111 and second lenses 211, the first light guide section 113 of the first lens 111 and the second light collecting section 212 of the second lens 211 communicate with each other.

[0033] 4 to 6, a plurality of second lens portions 214 arranged in the horizontal and vertical directions are formed in the second lens section 213 of each second lens 211. The second lens portions 214 protrude forward to different degrees, and the lens curvatures measured in the left-right direction of the second lens portions 214 in each row arranged in the vertical direction are different.

[0034] As shown in Figures 4 and 6, two adjacent second lens portions 214 are arranged in the vertical direction, and are configured so that the bottom of the upper second lens portion 214 protrudes forward relative to the top of the other second lens portion 214 below, creating a step 215.

[0035] Each second lens portion 214, together with the first lens portion 115 of each first lens 111, allows light transmitted in the forward direction to be projected as a second light pattern. In this embodiment, the second focusing sections 212 of adjacent second lenses 211 are connected to each other, so that the light focused by the second focusing sections 212 of each second lens 211 can not only transmit forward through the corresponding second lens section 213 on the front side, but also transmit forward through the second lens section 213 adjacent to it.

[0036] In addition, since the first light guide section 113 of the adjacent first lens 111 and the second light collecting section 212 of the adjacent second lens 211 are connected to each other, light that enters the first light guide section 113 of each first lens 111 can not only pass forward through the corresponding first lens section 114 at the front, but can also travel to the second light collecting section 212 of the adjacent second lens 211 and pass forward through the corresponding second lens section 213. Of course, this is not limited to the above, and in other embodiments, as long as the light refracted in the forward direction and transmitted by the second lens portion 214 of each second lens 211 can be projected to form the second light pattern together with the light refracted in the forward direction and transmitted by the first lens portion 115 of each first lens 111, the second light-concentrating sections 212 of adjacent second lenses 211 do not have to be connected to each other, and the first light guide section 113 of adjacent first lenses 111 and the second light-concentrating sections 212 of adjacent second lenses 211 do not have to be connected to each other.

[0037] In this embodiment, as described above, the first light pattern is a low beam, the second light pattern is a high beam, and the first light unit 1 has four first lenses 111 and four first light sources 121, each of which is arranged to form an F shape of the English alphabet. In addition, the second light unit 2 has three second lenses 211 and three second light sources 221, each of which is arranged together with the four first lenses 111 to form a larger F shape. However, the present invention is not limited thereto, and in other embodiments, for example, the first light pattern may be a high beam and the second light pattern may be a low beam, and the numbers of the first lenses 111, the first light sources 121, the second lenses 211, and the second light sources 221 may be changed according to needs and designs, and the arrangement method thereof may be changed from the above-mentioned F shape to, for example, other uppercase and lowercase letters of the English alphabet, Japanese hiragana and katakana, Korean hangul, numbers, or special symbols. For example, when arranging the above-mentioned components in an O-shape, a star shape, or the number 7, the number and arrangement of the first lenses 111, first light sources 121, second lenses 211, and second light sources 221 will be determined according to the shape.

[0038] Furthermore, in this embodiment, as described above, the plurality of second lenses 211 are arranged to extend the F shape of the English alphabet arranged by the plurality of first lenses 111, but in other embodiments, the plurality of first lenses 111 can be arranged to form a predetermined shape, and the plurality of second lenses 211 can be arranged to form another shape together with the plurality of first lenses 111. For example, the plurality of first lenses 111 can be arranged to form the O shape of the English alphabet, and the plurality of second lenses 211 can be arranged to form the Q shape of the English alphabet together with the plurality of first lenses 111.

[0039] 4, 5, 7, and 8, in each first lens 111, some of the first lens portions 115 have the same lens curvature while the other first lens portions 115 have different lens curvatures, and in each second lens 211, some of the second lens portions 214 have the same lens curvature while the other second lens portions 214 have different lens curvatures. Therefore, the light pattern of the light projected from the multiple first lens portions 115 can become a first light pattern, and the light pattern of the light projected from the multiple second lens portions 214 can become a second light pattern together with the light pattern of the light projected from the multiple first lens portions 115.

[0040] Of course, the present invention is not limited to this, and in other embodiments, as long as it is possible to realize that the light pattern of light projected from the multiple first lens portions 115 becomes a first light pattern, and the light pattern of light projected from the multiple second lens portions 214, together with the light pattern of light projected from the multiple first lens portions 115, becomes a second light pattern, the lens curvatures of the multiple first lens portions 115 may be the same or different, and the lens curvatures of the multiple second lens portions 214 may be the same or different.

[0041] In summary, the vehicle lamp device of the present invention has a configuration of multiple first lenses 111 arranged in a predetermined first shape, and the first lens portion 115 of each first lens 111 can cause the light transmitted forward to become a first light pattern, so that the first light-emitting unit 1 can not only emit light of a desired shape, but also project a desired light pattern (first light pattern).

[0042] Furthermore, by configuring the multiple second lenses 211 to be arranged in a predetermined second shape together with the multiple first lenses 111, and by making the light transmitted forward by the second lens portion of each second lens 211 form a second light pattern together with the light transmitted forward by the first lens portion 115 of each first lens 111, not only can the first light-emitting unit 1 and the second light-emitting unit 2 both emit light of a desired shape, but they can also project a desired light pattern (second light pattern).

[0043] As a result, the vehicle lamp device according to the present invention can emit light in a desired shape when viewed from the front, thereby producing a new visual effect and improving the aesthetic appearance of the display.

[0044] Although numerous specific details are set forth above to facilitate a thorough understanding of the present invention, it will be apparent to one of ordinary skill in the art that one or more other embodiments may be practiced without the specific details.

[0045] Although the preferred embodiments and modified examples of the present invention have been described above, the present invention is not limited to these, and is intended to encompass all modifications and equivalent configurations as various configurations falling within the spirit and scope of the broadest interpretation.
