Abstract
A motor vehicle headlight (80) comprises at least two modules (70) for light production, the radiation characteristics of at least one of the modules (70) being adjustable in a reference system associated with the headlight. Preferably, modules (70) of the headlight (80) have different radiation characteristics and the irradiation characteristics of at least two of the modules (70) overlap to form an adjustable radiation characteristic of the headlight (80).
Claims12
A motor vehicle headlamp, having at least two modules for light generation, an emission characteristic of at least one of the at least two modules being capable of moving in a reference system associated with the headlamp,
- wherein emission characteristics of the at least two modules are superimposed to give an emission characteristic of the headlamp;
- wherein each of the at least two modules has a light source and a module optical unit, said light source containing at least one light-emitting diode chip, said module optical unit being formed, at least in places, as at least one of the following optical elements:
- CPC, CEC, CHC, truncated-pyramid optical unit, and truncated-cone optical unit;
- wherein said module optical unit is in the form of one of a reflector and a solid body, the reflector having a light entry opening, a light exit opening, and side surfaces connecting the light entry opening to the light exit opening, the solid body having a light entry surface, a light exit surface, and side surfaces connecting the light entry surface to the light exit surface;
- and
- wherein at least one of said light entry opening and said light entry surface in an associated one of the at least two modules is a maximum of twice as large as a total radiation output surface of the at least one light-emitting diode chip of the associated one of the at least two modules.
