Abstract
A light-emitting surface element includes a connection device, a light-generating element having at least two electrical connections electrically conductively connected to assigned connection lines on the connection device, and at least one planar light-guiding element formed by injection-molding in a manner at least partly embedding an arrangement composed of connection device and light-generating element in the planar light-guiding element.
Claims9
A light-emitting surface element comprising:
- a connection device formed from a strip material and connection lines arranged on the strip material and has openings at regular distances along a longitudinal extent, through which openings the planar light-guiding surface element projects integrally;
- a light-generating element comprising a light-emitting diode formed as a chip size package and having at least two connections electrically conductively connected to assigned connection lines on the connection device;
- and
- at least one planar light-guiding element formed by injection-molding in a manner at least partly embedding an arrangement composed of connection device and light-generating element in the planar light-guiding element, wherein light from the light-generating element propagates along the planar light-guiding element in a direction perpendicular to the strip material.

A method for producing a light-emitting surface element comprising:
- providing a connection device;
- arranging a light-generating element on the connection device;
- and
- producing a planar light-guiding element by injection-molding in such a way that the light-generating element and the connection device are at least partly embedded into the light-guiding element, wherein the planar light-guiding element projects vertically with respect to the surface of the connection device and in the propagating direction of generated light.
