[0029] See also Figure 1 and Figure 2 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 or a taillight, and can be controlled to generate at least two lighting light shapes. The lighting light shapes are, for example, but not limited to, low light light shapes and high light light shapes. The vehicle lamp device includes an outer frame 1, a light shape frame body 2, a light emitting unit 3, a light distribution cover 4, and a heat dissipation unit 5.

[0030] The outer frame 1 is formed by stacking two F-shaped frames 11 front and back to define an installation space 10 (see FIG. Figure 3 ).

[0031] See also Figure 2 , Figure 3 and Figure 5 The light-shaped frame 2 is made of opaque material, installed in the installation space 10, and surrounds and defines six scattering domains 20 that penetrate from front to back and are arranged in an F shape. The light-shaped frame 2 includes six frame parts 21 arranged in an F shape and respectively defining the scattering domains 20, six horizontal shading plates 22 respectively arranged in the frame parts 21, and six vertical shading plates 23 respectively protruding on the top surfaces of the horizontal shading plates 22. Each of the horizontal shading plates 22 separates the corresponding scattering domain 20 into a first light-shaped area 201 and a second light-shaped area 202 spaced apart from each other.

[0032] In the six frame parts 21 of the present embodiment, two of the frame parts 21 are arranged horizontally on the top side, and five of the frame parts 21 are arranged vertically. The two adjacent first light-shaped areas 201 of the two horizontally arranged scattering domains 20 are connected (such as Figure 4 ), and the two adjacent second light-shaped areas 202 are also connected. The upper and lower adjacent second light-shaped areas 202 of the two upper and lower adjacent scattering domains 20 are connected to the first light-shaped area 201 (such as Figure 3 ). However, in other embodiments of the present invention, the adjacent first light-shaped areas 201 of the scattering domains 20 adjacent to each other in the transverse direction may not be connected, and the adjacent second light-shaped areas 202 may not be connected. The adjacent second light-shaped areas 202 of the scattering domains 20 adjacent to each other in the vertical direction may not be connected to the first light-shaped area 201.

[0033] See also Figure 2 , Figure 3 and Figure 6 , the light-emitting unit 3 is arranged at the rear side of the outer frame 1, and covers and shields the rear opening of the installation space 10. The light-emitting unit 3 includes six light-emitting parts 31 corresponding to the scattering domains 20 respectively. Each of the light-emitting parts 31 has a first light-emitting module 311 located at the top and emitting light toward the first light-shaped area 201 of the corresponding scattering domain 20, and a second light-emitting module 312 located at the bottom and emitting light toward the second light-shaped area 202 of the corresponding scattering domain 20. Each of the first light-emitting modules 311 has a plurality of first light sources 313, and a first reflector 314 for reflecting the light emitted by the first light sources 313 forward toward the corresponding first light-shaped area 201, and the first reflector 314 has a first opening 315 facing forward. Each of the second light-emitting modules 312 has a plurality of second light sources 316, and a second reflector 317 for reflecting the light emitted by the second light sources 316 forward toward the corresponding second light-shaped area 202, and the second reflector 317 has a second opening 318 facing forward. In this embodiment, the number of the first light sources 313 of each of the first light-emitting modules 311 is greater than the number of the second light sources 316 of each of the second light-emitting modules 312, but the implementation is not limited to this. In addition, in other embodiments of the present invention, each of the first light-emitting modules 311 can also be provided with only one first light source 313, and each of the second light-emitting modules 312 can also be provided with only one second light source 316.

[0034] See also Figure 2 , Figure 3 and Figure 5The light distribution cover 4 is arranged on the front side of the outer frame 1 and covers the opening arranged on the front side of the installation space 10. The light distribution cover 4 includes six lens portions 41 respectively corresponding to the scattering domains 20 and capable of allowing light to pass outward. Each of the lens portions 41 has a first lens area 411 and a second lens area 412 connected up and down. The first lens area 411 corresponds to the first light shape area 201 of the corresponding scattering domain 20, and the second lens area 412 corresponds to the second light shape area 202 of the corresponding scattering domain 20.

[0035] The details of the horizontal shading plate 22 and the vertical shading plate 23 of the light-shading frame 2 are as follows. Each of the horizontal shading plates 22 protrudes forward from the corresponding rear edge of the frame portion 21 to the front edge of the frame portion 21, and leans forward against the junction of the first lens area 411 and the second lens area 412 of the corresponding lens portion 41. Each of the vertical shading plates 23 protrudes upward from the top surface of the corresponding horizontal shading plate 22 into the corresponding first light-shading area 201, and partially shields the bottom of the first opening 315 of the corresponding first reflector 314, so as to block part of the light reflected forward to the corresponding first light-shading area 201, and ensure that the light shape projected forward from the light distribution cover 4 meets the regulatory requirements.

[0036] In this embodiment, the lens curvatures of the first lens area 411 are all different, and the lens curvatures of the second lens area 412 are all different. However, in other embodiments of the present invention, the lens curvatures of the first lens area 411 can also be designed to be partially the same or all the same, and the lens curvatures of the second lens area 412 can also be designed to be partially the same or all the same. In implementation, the lens curvatures of the first lens area 411 and the second lens area 412 can be designed according to the light form pattern that the lens portion 41 of the light distribution cover 4 is predetermined to form, and are not limited to the drawings.

[0037] The heat dissipation unit 5 is mounted on the light emitting unit 3 and includes six heat dissipation portions 51 respectively corresponding to the light emitting portions 31. Each heat dissipation portion 51 is disposed on the first light emitting module 311 and the second light emitting module 312 of the corresponding light emitting portion 31, wherein each heat dissipation portion 51 has a portion sandwiched between the first light emitting module 311 and the second light emitting module 312 of the corresponding light emitting portion 31. Since disposing the heat dissipation portion 51 on the light emitting unit 3 is a prior art and there are many ways to do so, it will not be described in detail.

[0038] When the vehicle lamp device of the present invention is installed on a vehicle and used as a headlamp, it can be controlled to switch between a low beam mode and a high beam mode, so the light distribution cover 4 is designed to be able to adjust the light penetrating forward into the low beam light shape and the high beam light shape.

[0039] When switched to the low beam mode, the second light source 316 of the light emitting portion 31 will be controlled to emit light, and the second reflector 317 will reflect the light generated by the second light source 316 forward toward the second light shape area 202 .

[0040] Since the second light-shaped areas 202 of the uppermost left and right adjacent scattering domains 20 are connected, the light passing through each second light-shaped area 202 will not only penetrate the second lens area 412 of the corresponding lens portion 41, but will also scatter into another connected second light-shaped area 202, and penetrate the second lens area 412 of another left and right adjacent lens portion 41. Since the adjacent second light-shaped areas 202 of any two upper and lower adjacent scattering domains 20 are connected to the first light-shaped area 201, the light passing through each second light-shaped area 202 will not only penetrate the second lens area 412 of the corresponding lens portion 41, but will also scatter into the first light-shaped area 201 connected below, and pass forward from the first lens area 411 corresponding to the first light-shaped area 201. With this design, in addition to making the light distribution cover 4 shine as a whole and present an F-shape, the light passing forward from the light distribution cover 4 will also cooperate to form the required low-beam light shape.

[0041] When switched to the high beam mode, the first light source 313 and the second light source 316 of the light-emitting portion 31 are controlled to emit light together, the first reflector 314 will reflect the light generated by the first light source 313 forward toward the first light shape area 201, and the second reflector 317 will reflect the light generated by the second light source 316 forward toward the second light shape area 202.

[0042] Since the first light-shaped areas 201 of the uppermost left and right adjacent scattering domains 20 are connected, and the second light-shaped areas 202 are also connected, the light passing through each first light-shaped area 201 and each second light-shaped area 202 will not only penetrate the first lens area 411 and the second lens area 412 of the corresponding lens portion 41, but will also be scattered into another first light-shaped area 201 and another second light-shaped area 202 that are connected, and will respectively penetrate the first lens area 411 and the second lens area 412 of another left and right adjacent lens portion 41. Since the adjacent second light-shaped areas 202 of any two scattering domains 20 that are adjacent to each other are connected to the first light-shaped area 201, the light passing through each second light-shaped area 202 will not only penetrate the second lens area 412 of the corresponding lens portion 41, but will also be scattered to the first light-shaped area 201 that is connected below, and will be transmitted forward from the first lens area 411 corresponding to the first light-shaped area 201. With this design, in addition to making the light distribution cover 4 shine as a whole and present an F-shape, the light transmitted forward from the light distribution cover 4 will also cooperate to form the required high light shape.

[0043] During implementation, in other embodiments of the present invention, when switching to the low beam mode or the high beam mode, it is also possible to drive one of the first light-emitting module 311 and the second light-emitting module 312 of each light-emitting portion 31 to emit light, so as to make the light penetrating the light distribution cover 4 form the required low beam light shape or the high beam light shape; or it is possible to drive one of the first light-emitting module 311 and the second light-emitting module 312 of a part of the light-emitting portion 31 to emit light, and drive both the first light-emitting module 311 and the second light-emitting module 312 of the remaining light-emitting portion 31 to emit light, so as to make the light penetrating the light distribution cover 4 form the required low beam light shape or the high beam light shape.

[0044] In this embodiment, the number of the scattering domains 20, the light-emitting portion 31, and the lens portion 41 is six, and they are arranged in the shape of the English letter F. However, in other embodiments of the present invention, the number of the scattering domains 20, the light-emitting portion 31, the lens portion 41, and the heat dissipation portion 51 is not limited to this, and the predetermined shape formed by the arrangement is not limited to the F shape, but can also be other uppercase English letters, lowercase English letters, Korean Hangul, Japanese Hiragana or Katakana, numbers or other special symbols. For example, it may be an O shape or a star shape, and the required number of the scattering domains 20, the light-emitting portion 31, and the lens portion 41 is set according to the actual requirements of the predetermined shape.

[0045] In addition, in the present embodiment, the first light-shaped area 201 and the second light-shaped area 202 of each scattering domain 20 adopt an up-down spacing design, which can be changed to a left-right spacing design, or a radial inside-outside spacing design according to the actual requirements of the predetermined shape, and the positions of the first light-emitting module 311 and the second light-emitting module 312 of each corresponding light-emitting portion 31, and the positions of the first lens area 411 and the second lens area 412 of each corresponding lens portion 41 are adjusted accordingly.

[0046] In summary, in the vehicle lamp device of the present invention, the first light-emitting module 311 and the second light-emitting module 312 of the light-emitting portion 31 can respectively emit light toward the first light-shape zone 201 and the second light-shape zone 202 of the corresponding scattering domain 20, and the light passes through the first light-shape zone 201 and the second light-shape zone 202 and respectively transmits light toward the first lens zone 411 and the second lens zone 412 of the corresponding lens portion 41. Regardless of making the first light-emitting module 311 emit light at the same time, or / and making the second light-emitting module 312 emit light at the same time, light transmits light from the lens portion 41. In addition to making the light distribution cover 4 illuminate as a whole and present the predetermined shape, the transmitted light cooperates to form the required low light beam shape and high light beam shape, so the purpose of the present invention can be achieved.

[0047] The above are only embodiments of the present invention and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
