• F21Y 2107/10 on concave supports or substrates, e.g. on the inner side of bowl-shaped supports
• F21Y 2107/20 on convex supports or substrates, e.g. on the outer surface of spheres
• F21Y 2107/30 on the outer surface of cylindrical surfaces, e.g. rod-shaped supports having a circular or a polygonal cross section
• F21Y 2107/40 on the sides of polyhedrons, e.g. cubes or pyramids
• F21Y 2107/50 on planar substrates or supports, but arranged in different planes or with differing orientation, e.g. on plate-shaped supports with steps on which light-generating elements are mounted
• F21Y 2107/60 on stacked substrates
• F21Y 2107/70 on flexible or deformable supports or substrates, e.g. for changing the light source into a desired form
• F21Y 2107/80 on articulated supports or substrates
• F21Y 2107/90 on two opposite sides of supports or substrates
