But if only LEDs with higher light efficiency are available, a dimmable circuit of the type described above must be used
If no dimmable wiring is installed, it may be possible due to the elapsed time between the motor vehicle headlamps or components inside the motor vehicle headlamps (light modules of the motor vehicle headlamps or Even within the individual optical modules) there is too much deviation in brightness

Embodiment Construction
[0042] First refer to figure 1 . figure 1 A flow chart showing a four-step method for regulating the luminous flux radiated by a motor vehicle lighting device 1 comprising at least one light source 2 for generating light and The optical unit 3 assigned to the at least one light source, wherein the main radiation axis 4 is assigned to the at least one light source, said optical unit 3 has at least one light coupling surface 5 ( image 3 ), the at least one light coupling surface is illuminated with light, and substantially all the light is coupled into the optical device 3 via the at least one light coupling surface.
[0043] If non-uniformly bright light sources are used in motor vehicle lighting, the motor vehicle, for example, can produce a non-homogeneous or non-uniformly bright light distribution. Light sources, for example designed as LEDs, which are used, for example, in motor vehicle light modules can therefore produce different luminous fluxes. This can lead to the ...

The invention relates to a method for adjusting a beam of light produced by a motor vehicular illumination device. The motor vehicular illumination device comprises at least one light source for generating light and at least one optical system for allocating the light source. The optical system is configured behind at least one light source in the direction of a main irradiation axis and is provided with at least one light coupling surface. Through the light coupling surface, all light is mainly coupled into the optical mechanism through the light coupling surface. The method comprises the following steps of a, acquiring an actual value of illumination strength; b), comparing the actual value with a preset objective value; c), calculating the relative position between at least one light coupling surface and at least one light source according to a method of equalizing the actual valve with the objective value; and d), placing at least one light coupling surface and at least one light source in the relative position by means of movement of at least one light coupling surface and at least one light source relative to each other.
