1. Lighting requirements
Lighting is a requirement for active vehicle safety and is controlled by national mandatory standards and must be followed. High beam, low beam and steering are completed by light design, while the front position lamp does not need to be strictly considered due to its wide requirements.
The following aspects affect the light distribution performance of the turn signal:
Problems when using lighting fixtures:
When using lighting fixtures, the light pattern must be stable and cannot jump when the vehicle is driving. If the light pattern jumps, it means that the reflective bowl (or lens) is not tightened or the light source of the bulb is loose. The main factor causing the reflective bowl to be not tightened is the lamp housing.
2. Exhaust structure introduction
Review the professional exhaust structure design plan to avoid the problem of causing water ingress to the headlights in the aftermarket.
Function of exhaust hole ribs:
Prevent rain from entering the protected structure. Protect the protected structure from being hit as little as possible and not easy to fall off when hit (the rib height cannot be too high, which will make assembly difficult, and cannot be too low, which will not play a protective role).
Why is there an exhaust structure? What are the general requirements for exhaust structures?
The exhaust mechanism should be designed at the appropriate position of the lamp to improve the heat exchange inside the lamp. For exhaust pipes that do not use glue, they should withstand a pull-off force of 1kgf. The exhaust pipe should be easy to install, and there should be some protective mechanisms to prevent rain from directly falling, splashing, and falling off.
Choice of exhaust structure position
Positions prone to water mist Positions that are easy to install Positions that are easy to make air circulation inside the lamp
