Abstract
A light-emitting assembly is provided in different embodiments. The light-emitting assembly comprises: a substrate (22); first light-emitting components (31) arranged on the substrate (22) along a first line and emitting first light of a first colour; second light-emitting components (33) arranged on the substrate (22) along a second line and emitting second light of a second colour, wherein the first line runs laterally next to the second line; and multiple optical waveguides (44) for guiding the light, which are arranged over the light-emitting components (31, 33), extend in the direction from the first line to the second line, and cross the first line and the second line.

A light-emitting assembly comprising:
- a substrate,
- first light-emitting components which are arranged on the substrate along a first line and emit first light of a first color,
- second light-emitting components which are arranged on the substrate along a second line and emit second light of a second color, wherein the first line runs laterally next to the second line,
- a plurality of rod-shaped optical waveguides for guiding light, which are arranged over the light-emitting components, extend in a direction from the first line to the second line and intersect the first line and the second line, and
- an edge body which (i) is formed in one piece with the optical waveguides, (ii) is arranged on the substrate, (iii) protrudes from the substrate in vertical direction, (iv) surrounds the light-emitting components in lateral direction, and (v) is transparent or translucent.
A light-emitting assembly comprising:
- a substrate,
- first light-emitting components which are arranged on the substrate along a first line and emit first light of a first color,
- second light-emitting components which are arranged on the substrate along a second line and emit second light of a second color, wherein the first line runs laterally next to the second line, and
- a plurality of rod-shaped optical waveguides for guiding light, which are arranged over the light-emitting components, extend in a direction from the first line to the second line and intersect the first line and the second line,
- wherein the light-emitting assembly comprises one of the following additional features:
- i) interspaces extending from one of the rod-shaped optical waveguides to another one of the rod-shaped optical waveguides extend along the first or second lines, and the interspaces are free of a potting material and/or of scattering particles, wherein light generated by the light-emitting components can exit from the light-emitting assembly through the interspaces in an unhindered manner;
- ii) light, which is generated by the light-emitting components and is not coupled into the optical waveguides, propagates between the optical waveguides in an unhindered manner along a vertical direction;
- or
- iii) light, which is generated by the light-emitting components and is not coupled into the optical waveguides, propagates in regions between the optical waveguides in an unhindered manner along a vertical direction and is mixed with the light mixed by the optical waveguides during and after passing through the optical waveguides.
A light-emitting assembly comprising:
- a substrate,
- first light-emitting components which are arranged on the substrate along a first line and emit first light of a first color,
- second light-emitting components which are arranged on the substrate along a second line and emit second light of a second color, wherein the first line runs laterally next to the second line, and
- a plurality of rod-shaped optical waveguides for guiding light, which are arranged over the light-emitting components, extend in a direction from the first line to the second line and intersect the first line and the second line,
- wherein the rod-shaped optical waveguides are spaced apart from one another so that light, which is generated by the light-emitting components and is not coupled into the rod-shaped optical waveguides, can pass the rod-shaped optical waveguides and exit from the light-emitting assembly without being coupled into the rod-shaped optical waveguides.
