[0019] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Please refer to the following: Figures 1-5 This utility model discloses an LED vehicle light with an exposed copper plate, comprising: a lamp body, a copper substrate 3 exposed on the outside of the lamp body, LED beads 9 welded to both sides of the copper substrate 3, and a bridge rectifier 5 welded to one end of the copper substrate 3. The lamp body includes aluminum parts A1 and B2. The copper substrate 3 is fixedly bonded between aluminum parts A1 and B2. The same end of aluminum parts A1 and B2 is fixedly connected by screws. Both aluminum parts A1 and B2 have heat dissipation vents 7 at the ends below the LED beads 9. A pin fan 6 is connected to one end of the bridge rectifier 5 at the copper substrate 3. Two high-brightness white LED beads 9 are used and welded to the copper substrate 3 to ensure the stability of the electrical connection and thermal conductivity.

[0023] Among them, the copper substrate 3 is exposed on the outside between aluminum parts A1 and B2. The bottom end of the bridge rectifier 5 is welded with double pins 11, which are fixedly connected to the inside of the base 10. The base 10 is made of high temperature resistant engineering plastic, and the double pins 11 are made of copper alloy. The base 10 is limited and snapped to one end of aluminum parts A1 and B2. Aluminum parts A1 and B2 are located on the outside of one end of the base 10 and are sleeved inside the back cover 12. Aluminum parts A1 and B2 are both provided with air inlets 8 on one side of the bridge rectifier 5. The air inlets 8 are connected to the heat dissipation vents 7. The end of aluminum part A1 near the bridge rectifier 5 is provided with a mating hole 13 that is opposite to aluminum part B2. The pin fan 6 is model 13510. Its heat dissipation structure: The lamp body is made of aluminum alloy (aluminum parts A1 and B2), and the exposed copper substrate 3 outside the lamp body is made of copper. It works with aluminum parts A1 and B2 to directly conduct heat dissipation to the outside (copper has a high thermal conductivity, which is conducive to rapid heat conduction). A 3510 pin fan 6 (16,000 RPM) is used to increase air convection (Yushi 3510 dual ball bearing fan: diameter 35mm, voltage available in 5V, 12V, and 24V, using dual ball bearings, with good stability and long service life, suitable for occasions requiring heat dissipation such as automotive LED headlights).

[0024] Assembly process: The light source board (copper substrate 3, LED beads 9 and bridge rectifier 5) of the LED is soldered and tightly bonded to the main body of the aluminum parts (aluminum parts A1 and B2) with thermally conductive silicone, so that the two sides of the copper substrate 3 are exposed between aluminum parts A1 and B2. Then, aluminum parts A1 and B2 are fixed with external screws.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
