Abstract
A light diffuser for a vehicle headlamp having a plurality of light sources that each is arranged inside a reflector is provided. The light diffuser is capable of representing a light-dark boundary of the low beams generated by the light sources without interruption, and is capable of diffusely scattering the daytime running lights emitted by the light sources so as to generate a homogenous exit of light for the light sources.
Claims14
A light diffuser for a vehicle headlamp having a plurality of light sources is arranged inside a reflector, wherein:
- the light diffuser is capable of representing a light-dark boundary of low beams generated by the light sources without interruption, and
- the light diffuser is capable of diffusely scattering daytime running lights emitted by the light sources, so as to generate a homogenous exit of light for the light sources.
A vehicle headlamp that comprises light sources arranged in a form of a matrix, wherein the light sources are suitable for emitting a daytime running light or a low beam via respective reflectors, and that comprises a light diffuser, wherein:
- the light diffuser is capable of representing a light-dark boundary of the low beams generated by the light sources without interruption, and
- the light diffuser is capable of diffusely scattering the daytime running lights emitted by the light sources, so as to generate a homogenous exit of light for the light sources.
A method for distributing light for a vehicle headlamp that comprises light sources, wherein the light sources are suitable for emitting a daytime running light or a low beam via respective reflectors, and that comprises a light diffuser, wherein:
- the light diffuser is capable of representing a light-dark boundary of the low beams generated by the light sources without interruption, and
- the light diffuser is capable of diffusely scattering the daytime running lights emitted by the light sources, so as to generate a homogenous exit of light for the light sources, the method comprising:
- emitting the daytime running lights in a first area of the vehicle headlamp, and
- emitting the low beam lights in a second area of the vehicle headlamp.
