AI Technical Summary
Existing rail vehicle headlights suffer from poor sealing, poor heat dissipation, and difficult maintenance. In particular, integrated headlights require the entire structure to be disassembled for repair when a malfunction occurs, which is costly and inconvenient.
It adopts a split headlamp structure, with the lens and lamp body designed separately. The lens is sealed to the headgear with an adhesive layer, and the lamp body is installed inside the headgear. The internal space of the headgear is used for heat dissipation. The beam is adjusted by a combination of adjusting bolts and springs. Copper pillars provide support and heat dissipation. The lens and headgear are fixed with structural adhesive.
It achieves excellent sealing and heat dissipation, simplifies the maintenance process, and only requires opening the inner panel for inspection, preventing moisture from entering the lamp body, and has an aesthetically pleasing appearance while reducing maintenance difficulty.
