The invention relates to a lighting structure (100) based on light-emitting diodes, a method for making such a structure and its uses. The structure comprises a first dielectric element (1a) with a substantially flat main surface (12a) associated with a first electrode (2a); a second dielectric element (1b) with a substantially flat main surface (12b) associated with a second electrode (2b) which is opposite the first electrode and in a different plane; at least one first light-emitting diode, called first LED (4), comprising a semiconductor chip (4) including, on first and second opposite sides, first and second electrical contacts (41, 42); the first electrical contact being electrically connected to the first electrode, the second electrical contact being electrically connected to the second electrode, at least the first element transmitting at least partly a radiation included in the ultraviolet, called UV, or the visible light.
