Through the three-layer lamp layout of upper, middle and lower, multi-dimensional warning coverage in the vertical direction is formed, which is suitable for different height operation environments, the layered design precisely controls the irradiation range of each lamp, avoids the light cross interference of the upper and lower lamps, and reduces the glare influence on the driver or surrounding personnel.

[0069] Referring to the drawingsFigure 6 As to the mounting structure of the lamp, the mounting structure further comprises a support frame 25, the support frame 25 is L-shaped, one end of the support frame 25 is connected with the vehicle body 27, and the shell 18 is mounted at the other end of the support frame 25. The support frame 25 is mounted at the front side of the vehicle, and two support frames 25 are provided and extend outward. The support frame 25 is mounted at two top corners of the vehicle head and extends outward, thereby ensuring the driving lighting requirement. The support frame 25 is a hollow pipe, and the support frame 25 is provided with a power supply wire for connecting the shell 18. The support frame 25 provides a wire channel, thereby avoiding that the exposed wire is eroded by the field mud. The driving lighting lamp 26 is mounted on the support frame 25, and the driving lighting lamp 26 is directed to the front side. The driving lighting lamp 26 is additionally provided at the outer end of the support frame 25, thereby expanding the lighting function without increasing the independent support frame.

[0070] The above only describes the preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and replacements can be made, and these improvements and replacements should also be considered as the protection scope of the present application.
