Abstract:
1. A columnar structure located on a transparent substrate having an inside and an outside, comprising: at least one emitting element, a light-guiding element, a dielectric element, and a conducting element; wherein the at least one emitting element of the columnar structure is a column that conducts and/or emits a particle flux; wherein a butt-end surface of the columnar structure faces the inside of the substrate and contacts it either immediately or indirectly; wherein the other butt-end of the columnar structure allows passage of emission exciting particles inside the column; wherein a portion of the lateral surface of the columnar structure is coated with a material that reflects the flux of particles propagating within the columnar structure; and wherein particle penetration also takes place through a part of the lateral surface of the column.
