[0034] Compared with the prior art, the vehicle lamp disclosed by the utility model is provided with the first baffle 210, so that the airflow blown by the heat dissipation fan 300 is all directed to the position of the lamp bead, the heat dissipation effect is improved, the first heat dissipation air duct 221 and the second heat dissipation air duct 231 are arranged towards the first lamp bead 101 and the second lamp bead 102 respectively, more airflow can be directed to the first lamp bead 101 and the second lamp bead 102, the heat dissipation effect of the first lamp bead 101 and the second lamp bead 102 is improved, and the heat dissipation efficiency of the vehicle lamp is ensured.
[0035] In a specific embodiment, the heat sink 200 comprises a second baffle 211 connected to the second side of the substrate, and arranged perpendicularly relative to the first baffle 210, and separates the second side of the substrate into a first heat dissipation area and a second heat dissipation area, and the first lamp bead 101 and the second lamp bead 102 are arranged opposite to the positions of the first heat dissipation area and the second heat dissipation area respectively; the first fin 220 is arranged in the first heat dissipation area, and the second fin 230 is arranged in the second heat dissipation area. The second baffle 211 is used to block the airflow and divide the airflow, the airflow blown by the heat dissipation fan 300 to the first heat dissipation area flows to the first lamp bead 101 under the action of the first heat dissipation air duct 221, the first baffle 210 and the second baffle 211, the airflow blown by the heat dissipation fan 300 to the second heat dissipation area blows to the second lamp bead 102 under the action of the second heat dissipation air duct 231, the first baffle 210 and the second baffle 211, so that the first lamp bead 101 and the second lamp bead 102 have better heat dissipation effect.
[0036] In combination Figure 1 which is a heat dissipation schematic diagram of the prior art, the outlet area of the heat dissipation fan 300 cannot cover the first lamp bead 101 and the second lamp bead 102 located at the end, so that the heat dissipation effect of the first lamp bead 101 and the second lamp bead 102 is general. In combination Figure 2 In the utility model, the airflow blown by the heat dissipation fan 300 can flow to the first lamp bead 101 and the second lamp bead 102 smoothly after being guided by the first heat dissipation air duct 221 and the second heat dissipation air duct 231 and blocked by the first baffle 210 and the second baffle 211, so that good heat dissipation effect is achieved. The lamp beads located between the first lamp bead 101 and the second lamp bead 102 can also be taken away enough heat for heat dissipation.
[0037] Specifically, one end of the first fin 220 and the second fin 230 extends to the first baffle 210 or the second baffle 211 and is fixedly connected thereto, so as to ensure the guiding effect of the airflow.
[0038] In order to avoid affecting the heat dissipation effect of the lamp bead, the first baffle 210 and the second baffle 211 are arranged in a staggered manner with the lamp bead.
[0039] Specifically, the first baffle 210 and the second baffle 211 can be an integral structure and are weldedly connected. The radiator 200 disclosed by the utility model can be prepared by die casting to meet the production requirements. The first baffle 210, the second baffle 211, the first fin 220 and the second fin 230 can be weldedly connected with the substrate.
[0040] In order to guarantee the heat dissipation effect, the air outlet of the heat dissipation fan 300 is arranged opposite the first heat dissipation area and the second heat dissipation area. Further, the air outlet of the heat dissipation fan 300 is symmetrically arranged relative to the first heat dissipation area and the second heat dissipation area to guarantee the uniform heat dissipation effect on the first lamp bead 101 and the second lamp bead 102.
[0041] In combination Figure 2 In some embodiments, each first fin 220 is arranged in parallel, and each second fin 230 is arranged in parallel, which is simple in structure and convenient to produce. In another embodiment, in combination Figure 3 The width of the first end of the first heat dissipation air duct 221 is smaller than the width of the second end, that is, the width of the end of the first heat dissipation air duct 221 close to the heat dissipation fan 300 is smaller than the width of the end away from the heat dissipation fan 300; the width of the first end of the second heat dissipation air duct 231 is smaller than the width of the second end, that is, the width of the end of the second heat dissipation air duct 231 close to the heat dissipation fan 300 is smaller than the width of the end away from the heat dissipation fan 300, so that the airflow blown by the heat dissipation fan 300 can reduce the flow rate when flowing through the first lamp bead 101 and the second lamp bead 102, and can fully exchange heat with the first lamp bead 101 and the second lamp bead 102.
[0042] In order to facilitate the positioning and installation of the lamp panel 100 and the substrate, a positioning protrusion is arranged on the first side of the substrate, and a positioning groove for embedding the positioning protrusion is arranged on the lamp panel 100, and the positioning and assembly of the lamp panel 100 and the substrate can be realized through the embedding cooperation between the positioning protrusion and the positioning groove. Specifically, the lamp panel 100 and the substrate can be connected by bolts or adhesively connected.
[0043] In order to further improve the heat dissipation effect, the heat interface material is filled between the lamp panel 100 and the substrate, and the heat interface material can effectively reduce the thermal resistance and improve the heat conduction efficiency between the lamp panel 100 and the substrate, thereby enhancing the heat dissipation effect.
[0044] In addition, the vehicle lamp further comprises a lamp shell 400, a lamp shade 410, a decorative frame, a module and the like structure, and specific reference can be made to the prior art, which will not be described here.
[0045] The vehicle disclosed by the utility model comprises the above-mentioned vehicle lamp, so it also has the above-mentioned structure and beneficial effects, and other structures refer to the prior art, which will not be described here.
