In an embodiment of the present invention, an automotive LED lamp with good heat dissipation performance is provided, which includes a base 100 and a lamp body 200. The lamp body 200 is fixedly connected to the base 100. The lamp body 200 includes: connecting seat 210, LED carrier plate 220 and lamp pearl paster 230. One end of the connecting base 210 is fixedly connected to the base 100. One end of the LED carrier 220 is fixedly connected to one end of the connecting socket 210. The LED carrier 220 is provided with a ventilation slot 221 and a mounting hole 222. A heat dissipating copper pipe 223 is detachably disposed in the mounting hole 222. The side surface of the LED carrier 220 is further provided with a vent 224. The lamp bead patches 230 are symmetrically arranged on two side surfaces of the LED carrier 220. One end of the lamp bead patch 230 is fixedly connected to the surface of the connecting base 210.

The ventilation grooves 221 and the ventilation holes 224 in the LED carrier 220 can increase the permeability of the LED carrier 220, and enhance the air fluidity in the LED carrier 220. Air can flow from the ventilation slots 221 and the ventilation holes 224, thereby removing heat from the LED carrier plate 220. The heat dissipation copper pipe 223 is installed in the installation hole 222 of the LED carrier 220, so that the installation is convenient, and the installation hole 222 can effectively fix the heat dissipation copper pipe 223. The side wall of the heat dissipation copper pipe 223 contacts with the wall of the LED carrier 220 and absorbs heat on the LED carrier 220, so as to effectively reduce the temperature of the LED carrier 220.

In other embodiments of the present invention, the ventilation groove 221 penetrates through the LED carrier 220, the connecting socket 210 and the base 100. The two ends of the ventilation groove 221 are opened and longitudinally penetrate through the LED car lamp main body, air at two ends of the LED car lamp can form convection, and therefore air fluidity in the ventilation groove 221 is enhanced, and the heat dissipation effect is improved.

In other embodiments of the present invention, the ventilation slot 221 is communicated with the mounting hole 222, and the heat dissipating copper pipe 223 is partially exposed in the ventilation slot 221. Because part of the surface of the heat dissipation copper pipe 223 is exposed in the ventilation groove 221, the heat dissipation of the surface of the heat dissipation copper pipe 223 is facilitated. After the heat dissipation copper pipe 223 absorbs the heat of the LED carrier 220, the temperature of the heat dissipation copper pipe itself will rise. When air flows in the ventilation groove 221, the air is in contact with the surface of the heat dissipation copper pipe 223 exposed in the ventilation groove 221, and the heat of the heat dissipation copper pipe 223 can be absorbed and taken away, so that the heat dissipation copper pipe 223 is cooled, and the heat absorption effect of the heat dissipation copper pipe 223 on the LED carrier plate 220 is improved.

In other embodiments of the present invention, the base 100 includes a heat dissipation housing 110 and a heat dissipation fan 120. The heat dissipation housing 110 is fixedly connected to the connecting base 210. The heat dissipation fan 120 is detachably installed in the heat dissipation housing 110 and faces the ventilation slot 221. Specifically, when the cooling fan 120 blows air, the flowing speed of the air in the ventilation slot 221 can be increased, and the faster the air flows, the more heat is taken away by the air, so that the cooling effect is enhanced.

In other embodiments of the present invention, a heat conducting plate 225 is disposed on the LED carrier 220, one side of the heat conducting plate 225 is fixedly connected to the surface of the LED carrier 220, and the other side is fixedly connected to the bead patch 230. Specifically, in the present embodiment, the thermal conductive plate 225 is a graphene thermal conductive plate 225. Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms, and has excellent heat conduction characteristics. The lamp bead patch 230 is powered on to emit light to generate heat. Due to the excellent thermal conductivity of the graphene thermal conductive plate 225, the heat generated by the lamp bead disk 230 is rapidly conducted to the periphery through the graphene thermal conductive plate. The heat is not easy to accumulate in the lamp bead patch 230, so that the situation that the lamp bead patch 230 is burnt due to overhigh temperature caused by that the heat is not emitted in time is effectively avoided.

In other embodiments of the present invention, a wire outlet 111 is formed on a side surface of the base 100, and the cable of the heat dissipation fan 120 extends out of the wire outlet 111. In this embodiment, the wire outlet 111 is a hole drilled in the side surface of the base 100, and a cable passes through the wire outlet 111 to be connected to an external power supply component, so as to take electricity from the outside and drive the lamp bead patch 230 and the rest of the heat dissipation components to work.

In other embodiments of the present invention, a plurality of heat dissipation fins 112 are circumferentially disposed on the peripheral side surface of the housing, and the distance between the heat dissipation fins 112 is 0.5mm to 0.8 mm. The thickness of the heat dissipation fins 112 should not be too large or too small, and if the thickness is too large, the distance between the heat dissipation fins 112 will be reduced, which is not favorable for the heat dissipation of the heat dissipation fins 112; if the thickness is too small, the deformation resistance of the heat dissipation fins 112 is reduced, and the heat dissipation fins are easily bent when receiving impact or impact. In this embodiment, the thickness of the heat dissipation fins 112 is 2mm, the distance between the heat dissipation fins is 0.6mm, and the depth of the heat dissipation fins 112 is 3mm to 5 mm. The bottom of the heat sink fins 112 is connected to the middle of the heat sink housing 110, which is beneficial to heat conduction of the heat sink housing 110.

In other embodiments of the present invention, the LED carrier 220 and the base 100 are both provided with rounded corners 300. In this embodiment, the rounded corner 300 is disposed on the LED carrier 220 and the base 100, so as to facilitate the insertion and removal of the lamp body 200.

In other embodiments of the present invention, the connection holder 210 is provided with a boss 211 and a sealing rubber ring 212. The number of the bosses 211 is plural and all disposed on the side surface of the connection seat 210. The sealing rubber ring 212 is sleeved on the connecting seat 210. In this embodiment, the boss 211 and the sealing rubber ring 212 both serve as a fixing and limiting function during installation.

In other embodiments of the present invention, the LED carrier 220 is made of copper, and the connecting socket 210 and the base 100 are made of aluminum alloy. Copper has excellent thermal conductivity, so the LED carrier 220 can conduct heat quickly, and has an effect of dissipating heat in time. Aluminum alloy density is little and intensity is high, uses connecting seat 210 and base 100 that the aluminum alloy made, and frivolous small and exquisite just has stronger anti deformability, runs into general collision or impact, and all be difficult for taking place deformation.
