Abstract: An electro-optical assembly, in particular a sensor assembly for detecting ambient light, includes a reflection surface, a lens body and an electro-optical component, in particular a light receiver. The component includes a depression having a main lens section, in particular a diverging lens section with a concave interior wall, and a converging lens section with a convex interior wall. The interior wall of the converging lens section is formed in such a way that the rays of the ray path which travel through the converging lens section to the electro-optical component hit the reflection surface in such way that the angle of incidence at the reflection surface is larger or the same as the critical angle of the total internal reflection at the reflection surface. In another aspect a method for detecting ambient light is described.

Abstract: A lens plate (10) for a rain and/or light sensor is proposed. The lens plate (10) has a base body (18), at least one light limitation structure (21), and at least one lens structure (28), the light limitation structure (21) extending into the base body (18) from a lower side (14) of the lens plate (10), a contour (27) of the light limitation structure (21) facing away from the lower side (14) of the lens plate (10) limiting the lens structure (28) circumferentially, and the contour (27) being substantially triangular. Furthermore, a rain and/or light sensor (8) is proposed.

Abstract: An optical assembly for an optical sensor device has a lens plate, a light source, and a light receiving unit. The lens plate includes a lens structure on a side associated with the light source and a light extraction structure on a side facing away from the light source. The lens structure has different local radii of curvature.
