[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] like Figure 1-5 The first embodiment of the present invention is shown. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an LED automobile lamp, comprising a transparent lampshade 1 and an extension shell 11 fixedly connected thereto and serving as a mounting base, the transparent lampshade 1 is provided with a placement cavity 12 inside, a substrate 2 is provided in the placement cavity 12, a plurality of light-emitting bodies 21 are installed through the substrate 2 from front to back, and two rows of heat sinks 22 are provided on the rear surface of the substrate 2, the two rows of heat sinks 22 are respectively located above and below the light-emitting bodies 21, two clamping plates 23 are respectively fixedly provided at the top and bottom ends of the substrate 2, two limiting grooves 13 are respectively provided at the top and bottom ends of the placement cavity 12, each clamping plate 23 is respectively clamped in the corresponding limiting groove 13, two detection probes 3 are respectively located at the edge positions on both sides of the placement cavity 12, and The two detection probes 3 are both located in the gap between the substrate 2 and the transparent lampshade 1. When the substrate 2 is installed in the placement cavity 12, the two clamping plates 23 at the top and bottom of the substrate 2 are respectively clamped in the two limiting grooves 13 at the top and bottom of the placement cavity 12. After the substrate 2 is clamped in, it is fixed with bolts. The heat sink 22 is a plurality of longitudinal fins arranged at intervals and a transverse metal plate connecting the longitudinal fins. One side of the thickness direction of each longitudinal fin is attached to the substrate 2. The heat sink 22 is on the substrate 2 and is located on the upper and lower sides of a row of light-emitting bodies 21, which is convenient for fully dissipating the heat of the light-emitting bodies 21 in use, avoiding heat accumulation in the gap between the substrate 2 and the transparent lampshade 1 and being unable to diffuse, thereby accelerating the generation of water mist. Accelerating the rapid diffusion of heat also helps to avoid the heat in the lampshade from expanding the gap of the lampshade.

[0027] Embodiment 2, as Figure 3 and Figure 4 As shown, two detection probes 3 are arranged at the top of the placement cavity 12, and the ports of the detection probes 3 are connected to the humidity sensor through connecting wires. The humidity sensor is also connected to the power adapter through connecting wires for powering the humidity sensor. Two mounting seats for clamping the detection probes 3 are arranged at the top of the placement cavity 12, and the power adapter is installed in the extension shell 11. The humidity sensor is installed inside the transparent lampshade 1 at the rear side of the substrate 2. The detection probe 3 is located in the gap between the substrate 2 and the transparent lampshade 1, and is close to the inner wall of the transparent lampshade 1, so that the humidity inside the transparent lampshade 1 can be monitored in real time. The detection probe 3 first transmits the detected humidity signal to the humidity sensor, and the humidity sensor transmits a signal after judging the humidity value. A signal receiver that is convenient for the driver to view can be arranged in the car to receive the signal data sent by the humidity sensor. The signal receiver has a warning light for the driver's intuitive judgment, so as to facilitate the driver to promptly inspect the cracks in the headlights and reduce the safety hazards caused by the headlights.

[0028] When the above embodiment is working, a detection probe 3 is installed inside the transparent lampshade 1, and the detection probe 3 is connected to the humidity sensor using a connecting line. The humidity sensor is connected to the power adapter using a connecting line, and a signal receiver is set in the car for the driver to view to receive the signal data sent by the humidity sensor. The signal receiver is equipped with a warning light to facilitate the driver's intuitive judgment. Two rows of heat sinks 22 are set on the rear side of the substrate 2 to fully dissipate the light-emitting body 21 in use, so as to avoid heat accumulation in the gap between the substrate 2 and the transparent lampshade 1 and unable to diffuse, thereby accelerating the generation of water mist. Accelerating the rapid diffusion of heat also helps to prevent the heat in the lampshade from expanding the gap of the lampshade.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
