[0037] Reference below Figure 1-Figure 5 The single-cup direct-emission integrated heat dissipation structure of a vehicle lamp according to an embodiment of the utility model is described.

[0038] like Figure 1-Figure 5 As shown, the single-cup direct-emission integrated heat dissipation structure of a vehicle lamp includes an integrated heat dissipation lamp frame 100, a metal upper cover 310, a metal lower cover 320, a lampshade bracket 410 and a lamp cover 420, and the above components constitute the overall outline of the lamp.

[0039] Specifically, the integrated heat dissipation lamp holder 100 is installed in the lamp holder of the passenger car, and the integrated heat dissipation lamp holder 100 is provided with installation holes for easy installation by the staff. The integrated heat dissipation lamp holder 100 has a hollow structure formed inside and is provided with a direct-light mounting seat 110, a lamp cup mounting seat 120 and a drive board mounting seat 130. The direct-light mounting seat 110, the lamp cup mounting seat 120 and the drive board mounting seat 130 are connected in sequence to ensure that the air in the direct-light mounting seat 110 can flow to the drive board mounting seat 130.

[0040] One end of the lampshade bracket 410 is connected to the integrated heat dissipation lamp holder 100 and covers the direct lamp mounting seat 110 and the lamp cup mounting seat 120, and the other end is open. The lamp cover 420 is installed at the opening of the lampshade bracket 410. The lampshade bracket 410 serves as a support for the lamp cover 420, which can prevent the lamp cover 420 from directly contacting the integrated heat dissipation lamp holder 100, and prevent the heat of the integrated heat dissipation lamp holder 100 from being transferred to the lamp cover 420 to accelerate the aging of the lamp cover 420.

[0041] The upper and lower ends of the drive board mounting base 130 are provided with a metal upper cover 310 and a metal lower cover 320, which are used to assist the integrated heat dissipation lamp holder 100 in dissipating heat. After the metal upper cover 310 and the metal lower cover 320 are directly connected to the integrated heat dissipation lamp holder 100, the heat of the integrated heat dissipation lamp holder 100 can be transferred to the metal upper cover 310 and the metal lower cover 320, thereby accelerating the heat dissipation of the integrated heat dissipation lamp holder 100.

[0042] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the direct-light mounting seat 110, the lamp cup mounting seat 120 and the driving board mounting seat 130 adopt an integrated structure. Specifically, the integrated structure of the three can improve the structural strength of the integrated heat dissipation lamp holder 100, and the integrated structure has better uniformity, which can improve the heat transfer efficiency between the direct-light mounting seat 110 and the driving board mounting seat 130.

[0043] In some embodiments of the present invention, the integrated heat dissipation lamp holder 100 is made of die-cast aluminum structure. Specifically, die-casting can obtain higher structural strength, and the density of metal aluminum is small, so as the structural material of the integrated heat dissipation lamp holder 100, the weight of the integrated heat dissipation lamp holder 100 can be effectively reduced.

[0044] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, a direct light board 210 is provided on the side wall of the direct light mounting seat 110 , and the back side of the direct light board 210 is in contact with the side wall of the direct light mounting seat 110 , and the heat generated by the direct light board 210 during operation is transferred to the direct light mounting seat 110 .

[0045] Specifically, the back plate of the direct light board 210 fits with the direct light mounting base 110 over a large area, and the heat generated by the direct light board 210 can be transferred to the direct light mounting base 110, which has a higher heat transfer efficiency and accelerates heat extraction.

[0046] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a lamp cup 220 is provided on the side of the lamp cup mounting seat 120 close to the direct lamp mounting seat 110, and a high-low beam switching mechanism 230 is provided above the lamp cup 220. Specifically, the high-low beam switching mechanism is a technical solution well known to those skilled in the art, and the high-low beam switching mechanism is not the main invention of the utility model, and will not be described in detail in this embodiment.

[0047] In some embodiments of the present invention, Figure 2-Figure 4As shown, the driving board mounting seat 130 is provided with a lamp bead driving board 240 and a light-emitting element 250. The light-emitting element 250 is arranged toward the side of the lamp cup 220. The driving board mounting seat 130 is provided with a fixing plate 131 with a hollow structure. The light-emitting element 250 is fixedly installed on the fixing plate 131, and the lamp bead driving board 240 is installed on the other side of the fixing plate 131 and is spaced a certain distance apart.

[0048] Specifically, the fixing plate 131 is located in the middle of the driving plate mounting seat 130, and the lamp bead driving plate 240 is arranged above the fixing plate 131. A certain distance is spaced between the lamp bead driving plate 240 and the fixing plate 131 to prevent the heat and hot air flow generated by the light emitting element 250 below the fixing plate 131 from affecting the lamp bead driving plate 240. The fixing plate 131 adopts a hollow structure to enable the heat generated by the light emitting element 250 during operation and the heated air to flow to the upper area through the hollow fixing plate 131.

[0049] In a further embodiment, Figure 3-Figure 5 As shown, a heat conductive grille 132 is provided on one side of the fixing plate 131, one side of the heat conductive grille 132 is close to the hollow part of the light emitting element 250 and the lamp bead driving plate 240, and a heat dissipation fan 260 is provided on the other side. The heat dissipation fan 260 is used to dissipate the heat accumulated in the driving plate mounting base 130.

[0050] Specifically, the heat conducting grille 132 is disposed on one side of the area above the fixing plate 131, and the heat dissipation fan 260 can discharge the hot air in the area above the fixing plate 131 and accelerate the heat dissipation of the driving plate mounting seat 130. The air flow formed by the heat dissipation fan 260 in the integrated heat dissipation lamp holder 100 continuously discharges the heat of the integrated heat dissipation lamp holder 100 to the outside, thereby reducing the operating temperature of the lamp set, allowing the lamp set to maintain stable operation and prolonging its service life.

[0051] In some embodiments of the present invention, Figure 1-Figure 5 As shown, the side walls of the driving board mounting seat 130 adopt a hollow structure. Specifically, the side walls of the driving board mounting seat 130 all adopt a hollow structure to accelerate air flow and assist the heat dissipation fan 260 in heat dissipation.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the side walls of the metal upper cover 310 and the metal lower cover 320 are hollowed out. Specifically, the metal upper cover 310 and the metal lower cover 320 are hollowed out in the area corresponding to the fixing plate 131, and the top of the cover is sealed.

[0053] In a further embodiment, the metal upper cover 310 and the metal lower cover 320 are both made of metal aluminum.

[0054] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
