摘要： The invention relates to a method for the production of a lighting element comprising at least one luminescent diode (11) and an inserted light-guiding body which is arranged in front of said luminescent diode (11) in the direction of the exit of the main light. The respective luminescent diodes are connected to the inserted light-guiding body (21) by an injection moulding process with transparent plastic (30). During injection moulding, at least 50 % of the surface of the luminescent diodes (11) is covered by the injected material (30). Also, the maximum wall thickness of the injected layer (30) does not exceed three-times the minimum wall thickness of said layer. Due to said invention, a method for the production of light-guiding illuminating elements is obtained by using at least one inserted light-guiding body, wherein the transparent partial illuminating bodies are connected together in a safe, rapid and precise manner with respect to the form thereof.
