Abstract

The invention relates to a method for producing light-guiding LED bodies, in two casting and/or injection molding steps, from a material which is free-flowing before being finally solidified. First, the electronic components, consisting of at least one light-emitting chip and at least two electrical terminals connected to said chip, are coated by means of casting or injection molding, and are then recoated by means of casting or injection moulding, at least in one region, in a larger LED end mold. The present invention provides a method for the production of light-guiding LED bodies, whereby almost all light-emitting diodes produced have the same optical characteristics, and rejection caused by damage of the individual LED electronic elements is avoided.
