Illumination device i.e. headlight, for passenger car, has reflector comprising elastically deformable partial areas in upper area and made from fiber-reinforced composite material, where partial areas are connected with actuators

The device (1) has a parabolic reflector (2), and a lighting unit (3) attached to the reflector and emitting light beams (L) that are reflected by the reflector. The reflector comprises elastically deformable partial areas (11) in an upper area, where the partial areas are connected with piezoelectr...

More Information
Summary:The device (1) has a parabolic reflector (2), and a lighting unit (3) attached to the reflector and emitting light beams (L) that are reflected by the reflector. The reflector comprises elastically deformable partial areas (11) in an upper area, where the partial areas are connected with piezoelectric-actuators (12) that are controlled by a control device (8). The reflector is made from fiber-reinforced composite material e.g. carbon fiber-reinforced or glass-fiber reinforced plastic, where the actuators are arranged in direct proximity of a middle axis of the reflector. Die Erfindung betrifft eine Kraftfahrzeug-Beleuchtungsvorrichtung (1), mit wenigstens einem Leuchtmittel (3) und wenigstens einem Reflektor (2), wobei der Reflektor (2) zumindest bereichsweise (11) elastisch verformbar oder verstellbar ausgebildet ist, derart dass durch gezielte, zumindest bereichsweise Verformung oder Verstellung des Reflektors (2) unterschiedliche Lichtverteilungen erzielbar sind. Es wird erfindungsgemäß ist vorgeschlagen, dass der Reflektor (2) zumindest bereichsweise aus einem faserverstärkten Verbundwerkstoff gebildet ist, um hierdurch eine leichte Verformbarkeit des Reflektors (2) zu erreichen.
