Housing
The headlamp housing has the following tasks:
-
Carrier of all headlamp components (cable, reflector, etc.)
-
Fixing on the vehicle body
-
Protection against exterior influences (humidity, heat, etc.)
-
Thermoplastics are used as housing material.
reflector
The main functional objective of the reflector is to capture the largest possible share of the luminous flux radiated by the bulb and direct it towards the road. There are a variety of different reflector systems available to enable headlamp designers to meet this requirement as efficiently as possible.
Projection Module
Projection modules are frequently used in modern headlamps due to their precisely calibrated beam path and high luminous flux. Due to different lens diameters, lighting functions and mounting possibilities, these modules can be used in a variety of different headlamp concepts.
Cover lenses
Cover lenses with dispersion optics have the task of deflecting, scattering or focusing the luminous flux collected by the reflector in such a way that the required light distribution, such as the cut-off line, is produced. This previous standard concept has now almost been completely replaced by non-patterned systems.
