  • Hybrid illumination system for head-up display
    Patent number: 8436952
    Abstract: A head-up display including a hybrid illumination system is provided. A light mixing unit provides a substantially homogenous light source to a reflective display unit. A concentrating optics unit collects ambient light and directs it towards the light mixing unit. At the same time, an electrically-powered light source emits light which is directed towards the light mixing unit. One or more optical elements direct the ambient light and the light source light into the light mixing unit for homogenization. A condensing unit receives the homogenized light mixture and outputs the condensed light to a polarizing beam splitter. A reflective display modulates the light from the polarizing beam splitter with information from a source of electrical information signals back towards the polarizing beam splitter. A projection unit projects the modulated light to create an image on a windshield.
