Description

Technical Field

[0001] The utility model relates to the technical field of LED vehicle lamps, in particular to a precision decoding LED vehicle lamp. Background Technique

[0002] LED vehicle lamps have the characteristics of high luminous efficiency, high color rendering, and long service life, and have been widely used in commercial lighting, indoor lighting, and automotive lighting.

[0003] During the long-term use of LED vehicle lamps, the LED lamps will generate heat, gradually increasing the heat inside the vehicle lamps. Whether the heat generated by the operation of the lamps is more or less, or the resulting temperature increase is more or less, the heat dissipation process is a slow process and cannot meet the heat dissipation situation when the heat is large or the temperature is high.

[0004] These previous heat dissipation structures and methods lead to extremely poor heat dissipation efficiency. If the heat dissipation situation cannot be met, the driving circuit will overheat and enter thermal protection, ultimately resulting in a decrease in the working current, causing the vehicle computer to fail to decode and the vehicle computer to display a fault code. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a precision decoding LED vehicle lamp, which solves the problem that these previous heat dissipation structures and methods lead to extremely poor heat dissipation efficiency. If the heat dissipation situation cannot be met, the driving circuit will overheat and enter thermal protection, ultimately resulting in a decrease in the working current, causing the vehicle computer to fail to decode.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: A precision decoding LED vehicle lamp includes an installation shell and a support plate fixedly connected to the top of the installation shell. A light-emitting component is fixedly installed inside the installation shell. A heat dissipation mesh frame is fixedly installed on the top of the support plate. A cover plate is fixedly installed on the top of the heat dissipation mesh frame through bolts. A connecting plate is fixedly installed at the bottom of the inner cavity of the heat dissipation mesh frame. An annular cover is fixedly installed inside the heat dissipation mesh frame. An electric fan is fixedly installed on the top of the connecting plate and inside the annular cover.

[0007] Preferably, a blade opening is provided on the top of the cover plate.

[0008] Preferably, a decoder mounting seat is fixedly installed on one side of the heat dissipation mesh frame by opening an opening.

[0009] Preferably, a connector is fixedly installed on one side of the decoder mounting seat.

[0010] Advantageous Effects

[0011] The utility model provides a precision decoding LED vehicle lamp. Compared with the existing technology, it has the following

[0012] Beneficial effects:

[0013] While the utility model emits bright light through the light-emitting component, the light-emitting component will supply power to the electric fan through the support plate and the connecting plate, so that the electric fan is energized to rotate and blow air. The air blown by the electric fan will be discharged through a plurality of notches on the surface of the heat dissipation mesh frame, so that the inside of the LED headlight can be well ventilated and cooled, effectively preventing the working current from decreasing due to too high temperature inside the LED headlight, which causes the vehicle computer not to decode, and ensuring the normal use of the LED headlight.
