Abstract

A display element for an electronic module configured as an optical waveguide arrangement is provided. The display element includes a first optical waveguide part with a first light-receiving surface and a first light-emitting surface. The display element further includes a second optical waveguide part with a second light-receiving surface and a second light-emitting surface. The first optical waveguide part and the second optical waveguide part are arranged opposite one another. A first guide is arranged on an inner side of the first optical waveguide part and a second guide is arranged on an inner side of the second optical waveguide part. The respective inner sides are arranged in relation to one another such that the designation label is configured to be fastened by the first and second guide.

First claim

What is claimed is:

1. A display element for an electronic module configured as an optical waveguide, comprising:
a first optical waveguide part having a first light-receiving surface and a first light-emitting surface;
a second optical waveguide part having a second light-receiving surface and a second light-emitting surface;
a first guide arranged on an inner side of the first optical waveguide part; and
a second guide arranged on an inner side of the second optical waveguide part, the respective inner sides being arranged in relation to one another such that a designation label is configured to be fastened by the first and second guides;
wherein the first optical waveguide part and the second optical waveguide part are arranged opposite one another; and
wherein:
the display module is configured to be placed in a recess of an electronic module having a housing;
the first optical waveguide part with its first light-receiving surface is arranged over a first light source and the second optical waveguide part with its second light-receiving surface is arranged over a second light source within the housing; and
the recess and the display element are configured to be joined together such that the inside of the housing, at the installation location of the display element, is protected from at least one of splash water and temporary submersion.

2. The display element of claim 1 , wherein at least one guide is configured as a slot extending lengthwise along the inner side.

3. The display element of claim 1 , wherein a contact edge for the designation label is on the inner sides.

4. The display element of claim 1 , wherein:
the first optical waveguide part and the second optical waveguide part are connected to a central part; and
an optical waveguide arrangement is configured as one plastic part.

5. The display element of claim 4 , wherein the display element is configured to be placed in a recess of a housing of the electronic module such that the recess is sealed by the optical waveguide arrangement.
