[0029] See also Figure 3 , 4 , 5. An embodiment of the vehicle lamp device of the present invention comprises a lens structure 2 located at the front, a light-emitting structure 3 located behind the lens structure 2 at an interval, a light-guiding structure 4 located between the light-emitting structure 3 and the lens structure 2, and a shielding structure 5 located between the light-guiding structure 4 and the light-emitting structure 3.

[0030] The lens structure 2 includes a lens element 21 located at the front. The lens element 21 is a piece of Figure 8 The double convex lens shown is mounted on a lamp holder (not shown) via a lens holder 22. Since the method of mounting the lens element 21 on the lamp holder via the lens holder 22 is common knowledge, the description is omitted here.

[0031] See also Figure 4 , 6 The light-emitting structure 3 includes a circuit board 31 spaced apart behind the lens element 21 of the lens structure 2, a main light unit 32 located in the middle of the circuit board 31 in the left-right direction and capable of generating the main light shape, and two auxiliary light units 33 located on the left and right sides of the main light unit 32, respectively.

[0032] The main light unit 32 includes main light sources 321 arranged in two groups vertically. The number of main light sources 321 in each group is not less than the number of main light sources 321 in the other group of main light sources 321 located below. Specifically, the main light unit 32 includes three main light sources 321 arranged in two groups vertically, and the main light sources 321 are arranged in an inverted triangle with a wide top and a narrow bottom, that is, the group located in the upper part includes two main light sources 321, and the group located in the lower part includes one main light source 321.

[0033] The two main light sources 321 located at the top are arranged side by side and can cooperate to produce the following Fig. 9The main light source 321 located below can produce a low beam light beam P11 as shown. Fig.10 In the present invention, the main light unit 32 can generate the low light beam P11 and the high light beam P12 at the same time, but in other embodiments of the present invention, it can also generate only one of the low light beam P11 and the high light beam P12. Each of the main light sources 321 is an LED chip and has a square light emitting portion.

[0034] Each of the auxiliary lamp units 33 includes a plurality of auxiliary lamp light sources 331 that are divided into a plurality of groups arranged vertically along a grouping direction D11. The grouping direction D11 extends in an arc-shaped manner downwardly toward each other.

[0035] Each group of auxiliary light sources 331 is arranged along an arrangement direction D12 away from the main light unit 32 and tilted downward and transverse to a corresponding grouping direction D11, and presents the following Figure 6 The dotted line represents an imaginary triangle.

[0036] Each group of the auxiliary light sources 331 is divided into several zones along a corresponding arrangement direction D12. The number of the auxiliary light sources 331 in each zone is not greater than the number of the auxiliary light sources 331 in another zone below. Specifically, each group of the auxiliary light sources 331 is divided into three zones in the order of one, one, and two along a corresponding arrangement direction D12 and arranged in a triangle.

[0037] In addition, since the grouping directions are curved downwards and extend toward each other as described above, the two groups of auxiliary light sources 331 of each auxiliary light unit 33 are arranged in a fan shape (or a trapezoidal shape in other embodiments), and the main light unit 32 is located at the center of the circle to which the fan belongs. Among them, an angle A11 between each arrangement direction D12 and a horizontal direction D21 is x degrees, 10≦x≦30, and x can also be an integer between 10 and 30. Each auxiliary light source 331 is an LED chip and has a square light-emitting portion.

[0038] See also Figure 5 , 7 8, the light guide structure 4 can project the light generated by the light emitting structure 3 toward the lens structure 2. The light guide structure 4 includes a light guide element 41, a main light guide unit 42 extending forward from the main light unit 32 and connected to the light guide element 41, and two auxiliary light guide units 43 extending forward from the auxiliary light units 33 and connected to the light guide element 41.

[0039] The light guide element 41 includes a connecting surface 411 connecting the main light guide unit 42 and the auxiliary light guide unit 43 , and a light emitting surface 412 opposite to the connecting surface 411 and facing the lens structure 2 .

[0040] The connecting surface 411 is a plane facing the rear. A distance L11 between the connecting surface 411 and the light emitting surface 412 increases from the center to the left and right sides (see Figure 8 (indicated).

[0041] The light exiting surface 412 is the Petzval focal plane of the lens structure 2. The concept of the Petzval focal plane is explained as follows: parallel light parallel to the optical axis of the lens element 21 will converge to form a focus, and parallel light from different directions will form a plurality of other focuses different from the focus after entering the lens element 21, and the other focuses cooperate with the focus to form the Petzval focal plane.

[0042] The main light guide unit 42 and the auxiliary light guide unit 43 have the same front-to-back length L12 (see Figure 8 The main light unit 42 includes three main light guide members 421 extending forward from the main light source 321 and connected to the connecting surface 411 of the light guide element 41 (see Figure 7 Each of the main light guide members 421 includes a main connecting end portion 422 integrally connected to the connecting surface 411 , and a main light incident end portion 423 opposite to the main connecting end portion 422 .

[0043] The main connecting end 422 of the main light guide member 421 located at the top is roughly in the shape of an arc, while the main connecting end 422 of the main light guide member 421 located at the bottom is in the shape of a trapezoid with a narrow upper base and a wide lower base.

[0044] The end surface of each main light incident end portion 423 faces the corresponding main light source 321 and has a rectangular shape, specifically a square.

[0045] Each of the auxiliary light guide units 43 extends along an extension direction D31 away from the main light unit 32 and tilted downward, and has an upper and lower width W11 that is transverse to the extension direction D31 and gradually widens along the extension direction D31. Each of the auxiliary light guide units 43 includes a plurality of groups of auxiliary light guide members 431 corresponding to the plurality of groups of auxiliary light sources 331.

[0046] In this embodiment, each of the auxiliary light guide units 43 includes two groups of auxiliary light guide members 431 arranged vertically. The auxiliary light sources 331 of each group are arranged in a triangle. Two groups of auxiliary light guide members 431 adjacent to each other in the same auxiliary light guide unit 43 are arranged in a fan shape (in other embodiments, they can also be a trapezoid).

[0047] The auxiliary light guides 431 of the same group are divided into three zones along a corresponding arrangement direction D12. The number of auxiliary light guides 431 in each zone of the same group is not less than the number of auxiliary light guides 431 in another zone of the same group located downstream (below) along the arrangement direction D12. Specifically, in this embodiment, the auxiliary light guides 431 of the same group are divided into three zones in the manner of one, one, and two, and the matching arrangement forms a triangle as described above.

[0048] Each of the auxiliary light guide members 431 extends forward and backward to be in a columnar shape, and includes an auxiliary connecting end portion 432 integrally connected to the connecting surface 411 , and an auxiliary light incident end portion 433 opposite to the auxiliary connecting end portion 432 .

[0049] The sub-connecting end portion 432 of one of the sub-light guides 431 in the same group is triangular in shape, and the tip thereof extends into between the main connecting end portions 422 of the two upper and lower adjacent main light guides 421. The sub-connecting end portions 432 of the sub-light guides 431 of the other sub-light guides 431 in the same group are trapezoidal in shape, and the width of each of the sub-connecting end portions 432 gradually widens along a respective arrangement direction D12. In this way, the sub-connecting end portions 432 of the sub-light guides 431 in the same group are arranged in a triangle as described above. In addition, the sub-connecting end portions 432 of the sub-light guides 431 of each sub-light guide unit 43 are arranged in a fan shape as described above.

[0050] An end surface of each of the auxiliary light incident ends 433 faces a corresponding auxiliary light source 331 and has a rectangular shape, specifically a square shape.

[0051] The shield structure 5 includes a plurality of plate holes 51, each of which corresponds to the main light source 321 and the auxiliary light source 331. Specifically, each of the plate holes 51 is rectangular. Since the shapes of the plate holes 51, the main light source 321, the auxiliary light source 331, the main light incident end 423 of the main light guide 421, and the auxiliary light incident end 433 of the auxiliary light guide 431 match each other and are rectangular, it is ensured that the light of the main light source 321 and the auxiliary light source 331 is incident from the main light incident end 423 and the auxiliary light incident end 433, and not from other parts of the main light guide 421 and the auxiliary light guide 431.

[0052] See also Figure 6, 7 10. In this embodiment, the main light source 321 and the main light guide 421 can cooperate to produce the following Fig.10 The low light beam P11 and the high light beam P12. The two main light sources 321 located at the top and the corresponding main light guides 421 can cooperate to form the low light beam P11 located at the bottom. The main light source 321 located at the bottom and the corresponding main light guide 421 can cooperate to form the high light beam P12 located at the top.

[0053] Since the main connecting end 422 of the main light guide member 421 located at the top is roughly arched in shape, Fig. 9 The low beam light beam P11 shown in the figure is relatively complete in shape of an arc. Since the main connecting end 422 of the main light guide 421 below is a trapezoid with a narrow upper bottom and a wide lower bottom, it can make Fig.10 The high light beam P12 shown in the figure has a relatively complete trapezoidal shape with a wide upper base and a narrow lower base.

[0054] See also Figure 6 , 7 11. In this embodiment, the auxiliary light source 331 and the corresponding auxiliary light guide 431 of the group located on the upper right side can form a Fig.11 A first turn signal light P21 is shown. Figure 6 , 7 12. In this embodiment, the auxiliary light source 331 and the corresponding auxiliary light guide 431 of the group located at the lower right side can form a Fig.12 The second turn signal light beam P22 is shown located above the first turn signal light beam P21.

[0055] Since the auxiliary connecting ends 432 of the auxiliary light guide members 431 of the same group are arranged in a triangle, Fig.12 The first turn signal light P21 and the second turn signal light P22 are both roughly triangular. Since the auxiliary connecting ends 432 of the auxiliary light guides 431 located on the same side in the left-right direction are arranged in a roughly fan-shaped manner, Fig.12 As shown, the first turn signal light shape P21 and the second turn signal light shape P22 can be matched and superimposed to present a relatively complete fan shape (or an approximate triangle).

[0056] See also Fig.13 This embodiment is suitable for installation on a motorcycle. When the motorcycle body tilts to the right due to a right turn, the first turn light beam P21 can illuminate a dark lighting area R11 between the low light beam P11 and the horizontal direction D21, thereby producing a safe turn lighting effect.

[0057] In summary, the function of the vehicle lamp device of the present invention is that the main lamp light source 321 can generate the main lamp shape of the low lamp light shape P11 and / or the high lamp light shape P12, and the arrangement of the auxiliary lamp light source 331 and the extension of the auxiliary light guide unit 43 can be used to generate the turn lamp shape. Therefore, the present invention provides a solution different from the existing products for the industry or consumers to choose, which can promote the healthy competition development of the industry and promote the welfare of consumers.
