Abstract

A module for a video wall is disclosed. In an embodiment a module includes a carrier, a plurality of components comprising at least one light-emitting structural element arranged on the carrier and an optical element, wherein the components are arranged at a prespecified lateral distance in relation to one another, wherein a retaining recess is formed between at least two components, wherein the retaining recess comprises at least two component recesses of two components which are arranged next to one another, wherein a retaining pin is fastened in the retaining recess, wherein the retaining pin is connected to the optical element, and wherein the optical element is configured to influence light irradiation onto the components and/or light emission from the components.

First claim

The invention claimed is:

1. A module for a video wall comprising:
a carrier;
a plurality of components comprising at least one light-emitting structural element arranged on the carrier; and
an optical element,
wherein the components are arranged at a prespecified lateral distance in relation to one another,
wherein a retaining recess is located between at least two components,
wherein the retaining recess comprises at least two component recesses of two components which are arranged next to one another,
wherein a retaining pin is fastened in the retaining recess,
wherein the retaining pin is connected to the optical element, and
wherein the optical element is configured to influence light irradiation onto the components and/or light emission from the components.

2. The module according to claim 1 , wherein the retaining recess extends into the carrier.

3. The module according to claim 1 , wherein the retaining pin is connected to the retaining recess in a force-fitting and/or interlocking manner.

4. The module according to claim 1 , wherein the retaining recess is arranged in corner regions of four components which are adjacent to one another, and wherein the retaining recess is formed by at least component recesses of the four components.

5. The module according to claim 1 , wherein the component recesses are configured in form of bevels of the components.

6. The module according to claim 1 , wherein the carrier comprises a circuit board with electrical lines and/or electrical circuits, and wherein the components are arranged on the circuit board.

7. The module according to claim 1 , wherein the module comprises a plurality of retaining recesses, wherein a plurality of retaining pins are inserted into the retaining recesses, wherein the retaining pins are connected to the optical element, and wherein the optical element covers the components.

8. The module according to claim 1 , wherein the optical element comprises at least one shading element for at least one structural element, and wherein the shading element is configured to reduce irradiation of light onto the structural element.

9. The module according to claim 8 , wherein the at least one shading element is arranged in a manner inclined at an angle not equal to 90° with respect to a plane of the structural element.

10. The module according to claim 8 , wherein the shading element comprises metal.

11. The module according to claim 1 , wherein the optical element comprises at least one radiation-guiding element for the electromagnetic radiation of at least one structural element, and wherein the radiation-guiding element comprises a lens.

12. The module according to claim 11 , wherein the radiation-guiding element is formed from plastic.

13. The module according to claim 1 , wherein the component comprises an arrangement of a plurality of light-emitting structural elements which are arranged in a grid, and wherein one structural element comprises at least one light-emitting element.

14. The module according to claim 1 , wherein the components are at a lateral distance of less than 0.8 mm.

15. The module according to claim 1 , wherein the retaining pin comprises a diameter which is less than one millimeter.

16. The module according to claim 1 , wherein the optical element comprises at least one shading element for at least one structural element, wherein the shading element is configured to reduce irradiation of light onto the structural element, wherein the optical element comprises at least one radiation-guiding element for the electromagnetic radiation of at least one structural element, and wherein the radiation-guiding element comprises a lens.

17. A module for a video wall comprising:
a carrier;
a plurality of components comprising at least one light-emitting structural element are arranged on the carrier; and
an optical element,
wherein the components are arranged at a prespecified lateral distance in relation to one another,
wherein a retaining recess is located between at least two components,
wherein the retaining recess comprises at least two component recesses of two components which are arranged next to one another,
wherein a retaining pin is fastened in the retaining recess,
wherein the retaining pin is connected to the optical element,
wherein the optical element is configured to influence light irradiation onto the components and/or light emission from the components,
wherein the retaining recess extends into the carrier,
wherein the retaining recess is arranged in corner regions of four components which are adjacent to one another, and
wherein the retaining recess is formed by at least component recesses of the four components.

18. A module for a video wall comprising:
a carrier;
a plurality of components comprising at least one light-emitting structural element are arranged on the carrier; and
an optical element,
wherein the components are arranged at a prespecified lateral distance in relation to one another,
wherein a retaining recess is located between at least two components,
wherein the retaining recess comprises at least two component recesses of two components which are arranged next to one another,
wherein a retaining pin is fastened in the retaining recess,
wherein the retaining pin is connected to the optical element,
wherein the optical element is configured to influence light irradiation onto the components and/or light emission from the components,
wherein the retaining recess extends into the carrier,
wherein the retaining recess is arranged in corner regions of four components which are adjacent to one another,
