HI Sascha, The geometry lighting is controlled by the normals on the geometry, perhaps you haven't attached any. See the osggeometry example.

Thanks Paul. I have maybe one further question. I have a High grid replaced by a Geometry object of Triangles. The only difference is that the Geometry has no shade and the light is worse. What methods in OSG available to set this settings for Geometry objects? Thanks.

Using these two methods, you need to iterate over the Drawables stored in your Geode. For each one, dynamic_cast it to a Geometry. Once you've done that, you can setColorArray() on the Geometry to replace the entire color array, or you can getColorArray() to get a reference to the existing color array and tweak individual colors within it.
