[0023] A new type of automotive LED lamp, referring to Figure 1 - Figure 2 , includes a lamp board and a heat dissipation base 1 connected to the lamp board. The lamp board includes a substrate 21, and encapsulation shells 22 are respectively arranged on the front and back surfaces of the substrate 21. First heat dissipation tubes 23 and second heat dissipation tubes 24 are respectively attached to both sides of the substrate 21. A light-emitting element 25 is arranged on the substrate 21. A first heat dissipation opening 26 and a second heat dissipation opening 27 are respectively arranged at intervals on each encapsulation shell 22. When the two encapsulation shells 22 are encapsulated on the substrate 21, the two first heat dissipation openings 26 are communicated to form a light projection opening for the light-emitting element 25 to project light, and at least 1 / 3 of the substrate 21 is exposed from the light projection opening.

[0024] Further, an installation groove 3 is recessed inward on the encapsulation shell 22, and the second heat dissipation opening 27 is located at the bottom of the installation groove 3.

[0025] Further, the second heat dissipation opening 27 is a strip-shaped hole, and decorative plates 4 are respectively arranged on both sides of the strip-shaped hole.

[0026] Further, the light-emitting element 25 is located at the upper end of the substrate 21, and the upper end surface of the second heat dissipation tube 24 is lower than the lower end surface of the light-emitting element 25.

[0027] Further, the horizontal height of the upper end surface of the first heat dissipation tube 23 is greater than the horizontal height of the upper end surface of the second heat dissipation tube 24, and the upper end surface of the first heat dissipation tube 23 is flush with the upper end surface of the substrate 21.

[0029] Further, both the first heat dissipation tube 23 and the second heat dissipation tube 24 are copper heat conduction tubes.

[0030] The working principle of the present utility model is as follows:

[0031] Figure 1 For a new type of automotive LED lamp after assembly, when the light-emitting element 25 generates heat during operation, the heat can be dissipated from the light projection opening formed by surrounding the first heat dissipation opening 26, or from the second heat dissipation opening 27, and at the same time, it can also be dissipated from the heat dissipation base 1. During the whole process, since at least 1 / 3 of the substrate 21 can be exposed through the light projection opening, the contact area between the substrate 21 and the air is greatly increased. By utilizing the air circulation, the heat can be dissipated from the substrate 21 in time, preventing the heat from accumulating on the substrate 21, thereby effectively avoiding the influence of the temperature rise caused by heat accumulation on the service life of the light-emitting element 25; on this basis, the present application also has the first heat dissipation tube 23 and the second heat dissipation tube 24 attached to both side portions of the substrate 21. The heat on the substrate 21 can be quickly transferred to the first heat dissipation tube 23 and the second heat dissipation tube 24 and then dissipated through the first heat dissipation tube 23 and the second heat dissipation tube 24 to prevent the heat from accumulating on the substrate 21. Taking the example that both the first heat dissipation tube 23 and the second heat dissipation tube 24 are provided with two, in order to prevent the second heat dissipation tube 24 from affecting the light projection range of the light-emitting element 25, the upper end surface of the first heat dissipation tube 23 must be lower than the lower end surface of the light-emitting element 25, and the first heat dissipation tube 23 and the second heat dissipation tube 24 are preferably arranged in parallel with each other. As Embodiment 1, both the first heat dissipation tube 23 and the second heat dissipation tube 24 can be selected as copper heat conduction tubes to be realized.

[0032] While the present application has the first heat dissipation tube 23 and the second heat dissipation tube 24 attached to both side portions of the substrate 21, it also has the first heat dissipation opening 26 and the second heat dissipation opening 27 provided on the encapsulation shell 22. The second heat dissipation opening 27 exposes a part of the substrate 21, which can accelerate the dissipation of part of the heat on the substrate 21. In addition, the first heat dissipation opening 26 and the second heat dissipation opening 27 of the present application surround to form a light projection opening for the light-emitting element 25 to project. The setting of the light projection opening can expose at least 1 / 3 of the substrate 21 and accelerate the dissipation of the heat on the substrate 21; with such a design, the present application improves the heat dissipation performance of the automotive LED lamp through various combined heat dissipation methods.

[0033] Based on the above technical solutions, the installation groove 3 of the present application is integrally formed and recessed inward, and the second heat dissipation port 27 is arranged at the bottom of the installation groove 3. This setting can reduce the thickness of the package shell 22 and also accelerate the heat dissipation on the substrate 21. As an example 1, the second heat dissipation port 27 can be set as a strip-shaped hole, and decorative plates 4 are respectively arranged on both sides of the strip-shaped hole. This setting can improve the overall aesthetics.

[0034] In the above technology, the heat dissipation seat 1 has a conventional structure, generally including structures such as heat dissipation fins and fans cooperating with each other. This is a mature technology in this technical field, and its working principle will not be elaborated herein.
