| 发明名称 | Optical sensing device for detecting ambient light in motor vehicles comprising a prism structure having a plurality of prisms designed to direct rays of a specific ambient light beam | ||
| 摘要 | An optical sensor device for the detection of ambient light is adapted to be coupled to a pane (10), in particular to a windshield of a vehicle. The optical sensor device has a sensor unit which includes at least one light receiver (22) for ambient light and a lens plate (12) for directionally coupling an ambient light beam (26) out of the pane (10) onto the light receiver (22). The lens plate (12) has a surface (18) facing the light receiver (22) and oriented substantially parallel to the pane (10) in the coupled condition of the optical sensor device. The surface (18) includes a prism structure (20) having a plurality of single prisms (24) which are designed to direct the rays of a specific ambient light beam (26) defined by a principal direction (A) and an aperture angle onto the light receiver (22). | ||

| 主权项 | 1. An optical sensor device for the detection of ambient light, which is adapted to be coupled to a pane (10), comprising a sensor unit which includes at least one light receiver (22) for ambient light and a lens plate (12) for directionally coupling an ambient light beam (26) out of the pane (10) onto the light receiver (22), the lens plate (12) having a substantially planar first surface (16) facing the pane (10) and a second surface (18) facing the light receiver (22) and oriented substantially parallel to the pane (10) in the coupled condition of the optical sensor device, wherein the second surface (18) includes a prism structure (20) having a plurality of single prisms (24) which are designed to direct the rays of a specific ambient light beam (26) defined by a principal direction (A) and an aperture angle onto the light receiver (22), wherein the single prisms (24) include inclined surfaces that focus the rays of the ambient light beam (26) onto the light receiver (22), the single prisms (24) further including surfaces adjacent to the inclined surfaces, the surfaces adjacent to the inclined surfaces being oriented respectively parallel to the rays of the ambient light beam (26). | ||
