Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to an LED front combination headlight for engineering machinery and agricultural machinery. Background Technology

[0002] Construction machinery and agricultural machinery (such as tractors, combine harvesters, and agricultural transport vehicles) are the core representatives of non-road mobile equipment. They often operate continuously day and night, in extremely harsh environments, and under complex and ever-changing working conditions. Their lighting systems, especially the front combination headlights, are not only related to work efficiency and operational safety, but are also key components to ensure all-weather, all-time construction and agricultural operations.

[0003] Currently, the internal optics and structural design of many LED headlight combinations remains relatively rudimentary. The arrangement of functional modules (such as high beam modules, low beam modules, and turn signal modules) often only meets basic optical distribution requirements without deep integration or spatial optimization. This stacked or dispersed layout directly results in a non-compact structure and unreasonable arrangement of the lamp, easily leading to excessively high local temperatures within the lamp and significant light decay. This, in turn, affects the light output and operational reliability of the LED headlight combination under long-term harsh operating conditions, reducing its lifespan. Utility Model Content
