Head light for a motor vehicle
First Claim
Patent Images
1. A head light for a motor vehicle comprising:
- a light source for generating a beam of light;
a red light filter for eliminating at least the substantial portion of red light, but not green light or blue light, from the light generated by the light source; and
an electronic beam steering module arranged downstream of the red light filter and comprising one or more electrically controllable liquid crystal layers configured to steer the filtered light beam in different directions depending on a received control signal without mechanical movement, wherein the electronic beam steering module has a performance wavelength which lies between the wavelength of green light and the wavelength of blue light such that the electronic beam steering module is specifically configured for steering the light filtered by the red light filter.
