Abstract

A light-emitting element includes at least one flat light emitter having a first electrical contact portion formed on a side surface, and a housing partially surrounding the side surface of the flat light emitter, the housing including a second electrical contact portion formed on an inner surface of the housing and configured to mate with the first electrical contact portion.

Claims (24)

1. A light-emitting element, comprising:

at least one flat light emitter having a side surface, an edge region, a first conductive surface element arranged on the side surface, and an element with an upper side and a lower side; and

a housing having a second conductive surface element arranged on an inner surface of the housing,

the flat light emitter is received in the housing such that it surrounds the side surface of the flat light emitter at least partially,

the inner surface of the housing facing the side surface of the light emitter with the first and second conductive surface elements forming an electrical contact there between, and the flat light emitter is held in the housing by cooperation between the side surface of the light emitter and the inner surface of the housing,

wherein the first conductive surface element extends over the edge region of the flat light emitter from the upper side of the element of the flat light emitter to the side surface of the flat light emitter so that a contact surface formed on the upper or lower side of the element is extended to the side surface of the flat light emitter via the first conductive surface element to make contact with the second conductive surface element, and

wherein an entire surface of the lower side and an entire surface of the upper side of the flat light emitter are not covered by the housing.

2. The light-emitting element as claimed in claim 1 , wherein the element of the flat light emitter is a glass element.

3. The light-emitting element as claimed in claim 1 , wherein the first conductive surface element is fastened on the side surface of the flat light emitter and the second conductive surface element is fastened on the inner surface of the housing by bonding, welding or soldering.

4. The light-emitting element as claimed in claim 1 , wherein, in order to form the electrical contact, a second electrical contact surface is formed on the inner surface of the housing, said inner surface facing the side surface of the flat light emitter.

5. The light-emitting element as claimed in claim 1 , wherein the electrical contact is formed by spring-mounted contact elements.

6. The light-emitting element as claimed in claim 1 , wherein the housing is in the form of a frame.

7. The light-emitting element as claimed in claim 1 , wherein, in order to form a holder for the flat light emitter in the housing, the housing and/or the flat light emitter has/have a latching mechanism.

8. The light-emitting element as claimed in claim 1 , wherein, in order to form a holder for the flat light emitter in the housing, the housing has an inner surface, which is conical and/or the side surface of the flat light emitter is conical.

9. The light-emitting element as claimed in claim 1 , wherein the flat light emitter has an organic light emitter or is in the form of such an organic light emitter.

10. The light-emitting element as claimed in claim 1 , wherein the element of the flat light emitter is a substrate glass or a covering glass.

11. A light-emitting element, comprising:

at least one flat light emitter having a side surface, an edge region, a first conductive surface element arranged on the side surface, and an element with an upper side and a lower side; and

a housing having a second conductive surface element arranged on an inner surface of the housing,

the flat light emitter is received in the housing such that it surrounds the side surface of the flat light emitter at least partially,

the inner surface of the housing facing the side surface of the light emitter with the first and second conductive surface elements forming an electrical contact there between, and the flat light emitter is held in the housing by cooperation between the side surface of the light emitter and the inner surface of the housing,

wherein the first conductive surface element extends over the edge region of the flat light emitter from the upper side of the element of the flat light emitter to the side surface of the flat light emitter so that a contact surface formed on the upper or lower side of the element is extended to the side surface of the flat light emitter via the first conductive surface element to make contact with the second conductive surface element, and

wherein an entire surface of the lower side of the flat light emitter is exposed, and

wherein the element of the flat light emitter comprises a substrate glass and a covering glass and wherein lateral dimensions of the covering glass are smaller than lateral dimensions of the substrate glass so that the covering glass and the substrate glass do not terminate flush with one another at their edges.
