[0039] See also Figure 1 , Figure 2 and Figure 3 An embodiment of the vehicle lamp device of the present invention is suitable for installation on a vehicle (not shown), can be used as a headlight, and can be controlled to produce at least two lighting light shapes. The lighting light shape is, for example, but not limited to, a low light light shape and a high light light shape. The vehicle lamp device includes a first light-emitting unit 1, a second light-emitting unit 2 located below the first light-emitting unit 1, a mounting frame 3 and a heat dissipation unit 4 for clamping and positioning the first light-emitting unit 1 and the second light-emitting unit 2 front and back, and a transparent lampshade 5 and a lamp housing 6 that are assembled front and back and cooperate to define an installation space. The first light-emitting unit 1 and the second light-emitting unit 2 will be arranged and positioned in the installation space via the mounting frame 3 and the heat dissipation unit 4. Because the structure of the lampshade 5 and the lamp housing 6 is not the technical focus of the present invention, it will not be repeated below.

[0040] See also Figure 4 , Figure 5 and Figure 6 The first light-emitting unit 1 includes a first lens module 11 embedded in the mounting frame 3, and a first light-emitting module 12 connected to the heat dissipation unit 4 and located at the rear side of the first lens module 11. The first lens module 11 has four first lens bodies 111 connected in an integral manner and arranged in an F shape. The first light-emitting module 12 has four first light sources 121 respectively located at the rear sides of the first lens bodies 111.

[0041] Each first lens body 111 has a first light-collecting section 112 for converging the light emitted by the corresponding first light source 121 forward, a light-passing section 113 located in front of the first light-collecting section 112 and used to guide the light converged by the first light-collecting section 112 forward, and a first lens section 114 exposed on the front side of the mounting frame 3 and refracting the light from the light-passing section 113 forward. The light-passing sections 113 of two adjacent first lens bodies 111 are connected to each other.

[0042] Each first lens segment 114 has a plurality of first lens portions 115 arranged in multiple rows in a horizontal direction. The first lens portions 115 have different degrees of arc protrusion forward, and the curvature of the left and right arcs is different from that of the upper and lower arcs. The bottom end of each first lens portion 115 arranged on the top will protrude forward relative to the top end of each first lens portion 115 arranged on the bottom, so that a step 116 is formed between the two first lens portions 115 arranged on the top and bottom. The first lens portions 115 of the first lens body 111 can make the light refracted forward and transmitted cooperate to project into the first light shape. In this embodiment, the first light shape is a low beam light shape.

[0043] In this embodiment, the light passage sections 113 of two adjacent first lens bodies 111 are connected to each other, so the light entering the light passage section 113 of each first lens body 111 will not only pass forward from the first lens section 114 on the front side, but will also be scattered to the light passage section 113 of another adjacent first lens body 111 and pass forward from the other adjacent first lens section 114. However, in other embodiments of the present invention, it is not necessary for the light passage sections 113 of two adjacent first lens bodies 111 to be connected, as long as the light refracted and transmitted forward from the first lens portion 115 of the first lens body 111 can be coordinated and projected into the first light shape. In addition, in other embodiments of the present invention, it is not necessary for each first lens body 111 to have the light passage section 113, as long as the light gathered forward by the first light-focusing section 112 can reach the first lens section 114 and refract and pass forward.

[0044] See also Figure 4 , Figure 5 and Figure 6 The second light emitting unit 2 is located below the first light emitting unit 1 and can cooperate with the first light emitting unit 1 to project a second light shape. The second light emitting unit 2 includes a second lens module 21 embedded in the mounting frame 3, and a second light emitting module 22 installed in the heat dissipation unit 4 and located at the rear side of the second lens module 21. In this embodiment, the second light shape is a high light light shape.

[0045] The second lens module 21 has three second lens bodies 211 which are connected and arranged in an integral manner from top to bottom and are arranged together with the first lens body 111 to form a larger F-shape. The second light-emitting module 22 has three second light sources 221 which are respectively located at the rear side of the second lens body 211. Each second lens body 211 has a second light-focusing section 212 for focusing the light emitted by the corresponding second light source 221 forward, and a second lens section 213 which is exposed at the front side of the mounting frame 3 and refracts the light focused forward by the second light-focusing section 212 and transmits it forward. The second light-focusing sections 212 of two adjacent second lens bodies 211 are connected in the same body. The light-passing section 113 of the adjacent first lens body 111 is connected in the same body with the second light-focusing section 212 of the second lens body 211.

[0046] Each second lens segment 213 has a plurality of second lens portions 214 arranged in multiple rows in a horizontal direction. The second lens portions 214 have different forward arc protrusions, and the left and right curvatures of the upper and lower rows are different. The bottom end of each second lens portion 214 arranged on the top protrudes forward relative to the top end of each second lens portion 214 arranged on the bottom, so that a step 215 is formed between each second lens portion 214 arranged on the top and another second lens portion 214 arranged on the bottom.

[0047] The second lens portion 214 of the second lens body 211 can cooperate with the first lens portion 115 of the first lens body 111 so that the light refracted and transmitted forwards can cooperate and be projected to form the second light shape.

[0048] In this embodiment, the second light-focusing segments 212 of two adjacent second lens bodies 211 are connected to the same body, so the light focused forward by the second light-focusing segment 212 of each second lens body 211 will not only pass forward from the second lens segment 213 on the front side, but will also be scattered to another adjacent second light-focusing segment 212 and pass forward from another adjacent second lens segment 213.

[0049] The light passing section 113 of the adjacent first lens body 111 is connected to the second light focusing section 212 of the second lens body 211, so the light passing through the light passing section 113 of the first lens body 111 will not only pass forward from the first lens section 114 on the front side, but will also be scattered to the second light focusing section 212 of the adjacent second lens body 211 and pass forward from the adjacent second lens section 213.

[0050] However, in other embodiments of the present invention, it is not necessary for the second light-focusing sections 212 of two adjacent second lens bodies 211 to be connected, and it is not necessary for the light-passing section 113 of the adjacent first lens body 111 to be connected to the second light-focusing section 212 of the second lens body 211, as long as the light emitted from the second lens portion 214 of the second lens body 211 can cooperate with the light emitted from the first lens portion 115 of the first lens body 111 to be projected into the second light shape.

[0051] In the present embodiment, the first light shape is a low light light shape, the second light shape is a high light light shape, the number of the first lens bodies 111 of the first light-emitting unit 1 is four, and the predetermined shape arranged therein is the letter F of the English letter, the number of the second lens bodies 211 of the second light-emitting unit 2 is three, and the other predetermined shape arranged with the first lens body 111 is a larger letter F of the English letter, but during implementation, in other embodiments of the present invention, the types of the first light shape and the second light shape can be interchanged, and the number of the first lens body 111 and the first light source 121, as well as the number of the second lens body 211 and the second light source 221 are not limited to the above embodiments, and can be increased or decreased as required by the predetermined shape to be arranged.

[0052] In addition, the predetermined shape is not limited to the English letter F, but can also be other uppercase and lowercase English letters, Korean Hangul, Japanese Hiragana or Katakana, numbers or other special symbols. For example, it can be an O shape, the number 7, or a star shape.

[0053] Furthermore, in implementation, in addition to being used to extend and enlarge the predetermined shape (F-shape) formed by the arrangement of the first lens bodies 111 as disclosed in the design concept of this embodiment, in another embodiment of the present invention, the first lens bodies 111 can be arranged in coordination to form a predetermined shape, and the second lens bodies 211 and the first lens bodies 111 can be coordinated to form another predetermined shape. For example, the first lens bodies 111 can be arranged to form an O-shape, and the second lens bodies 211 and the first lens bodies 111 can be coordinated to form a Q-shape, etc., but the implementation is not limited to the above-mentioned embodiments.

[0054] See also Figure 4 , Figure 5 , Figure 7 and Figure 8In this embodiment, the lens curvatures of the first lens portion 115 are partially the same and partially different, and the lens curvatures of the second lens portion 214 are also partially the same and partially different, so the light transmitted from the first lens portion 115 can be coordinated to be projected into the first light shape, and the light transmitted from the second lens portion 214 can be coordinated with the light transmitted from the first lens portion 115 to be projected into the second light shape. However, in other embodiments of the present invention, the lens curvatures of the first lens portion 115 can be the same or different, and the lens curvatures of the second lens portion 214 can be the same or different, as long as the light transmitted from the first lens portion 115 can be coordinated to be projected into the first light shape, and the light transmitted from the second lens portion 214 can be coordinated with the light transmitted from the first lens portion 115 to be projected into the second light shape.

[0055] In summary, the vehicle lamp device of the present invention, through the structural design of the first lens body 111 arranged into the predetermined shape, and the design of the first lens portion 115 of the first lens body 111 that can make the light penetrating forward cooperate and project into the first light shape, the first light-emitting unit 1 can emit light as a whole to present the predetermined shape, and can also project the required first light shape forward.

[0056] Furthermore, through the structural design of the second lens body 211 that cooperates with the first lens body 111 to be arranged into the other predetermined shape, and the design that the light emitted from the second lens portion 214 of the second lens body 211 can cooperate with the light emitted from the first lens portion 115 of the first lens body 111 to project the second light shape, the second light-emitting unit 2 and the first light-emitting unit 1 can emit light as a whole and present the other predetermined shape, and can also project the required second light shape forward, so that the purpose of the present invention can be achieved.
