Headlamp is the essential product in the vehicles. Nowadays, the consumers are asking increasingly demanding requirements in their needs. This paper is to present assembly tolerance reference for headlamp photometric performance that installs the led projection module through photometric analysis. The projection module was installed the one unit that assembled the four unit parts. The four parts are light-source, reflector, light-shield and projection lens. The tolerance in the assembly module is an inevitable trouble. It makes a quality problem of lamp product. And so, the projection module needs an establishment of the tolerance reference. This paper studied how to keep the tolerance of the each unit part to satisfy the photometric regulations.

This Study provides development of the virtual driving simulation and evaluation of the headlamp performance in a digital road environment. There are a lot of Obstacles on the road such as pedestrians, signal plates, tunnels, intersection and curved road. For road safety, These have to be considered by Engineers to prevent car accident in advance. This paper studied how to evaluate the light distribution performance on the road such as Glare, Evenness, Brightness and so on. Virtual driving simulation is helpful to predict the problem of the Headlamp and make the period of the headlamp development short.
