Abstract

A dual graphic label for an input element of a control device for selectively displaying a first graphic information and a second graphic information includes a first light source, a second light source, an optical masking shield, a light conducting body, and a display face. The optical masking shield has a light blocking surface with a light permeable area in a shape of the first graphic information. The light conducting body has a surface with a light diffusion area in a shape of the second graphic information. The first light source emits a first light ray and the second light source emits a second light ray. The optical masking shield is arranged between the first light source and the light conducting body, and the light conducting body is arranged between the display face and the optical masking shield.

First claim

The invention claimed is:

1. A dual graphic label for an input element of a control device for selectively displaying a first graphic information and a second graphic information, the dual graphic label comprising:
a first light source configured to emit a first light ray;
a second light source configured to emit a second light ray;
an optical masking shield comprising a light blocking surface with a light permeable area in a shape of the first graphic information;
a light conducting body comprising a surface with a light diffusion area in a shape of the second graphic information;
a light guiding unit arranged between the second light source and the light conducting body, the light guiding unit being configured to guide a light ray from the second light source to the light conducting body;
an opaque carrier comprising a casing having an outer surface comprising the optical masking shield, wherein the light permeable area in the shape of the first graphic information comprises a hollow cutout in the outer surface of the opaque carrier in the shape of the first graphic information, the outer surface also comprising a slot into which the light guiding unit is insertable so as to couple the light guiding unit with the light conducting body;

and
a display face,
wherein
the optical masking shield is arranged between the first light source and the light conducting body, and the light conducting body is arranged between the display face and the optical masking shield,
the first light ray travels from the first light source to the light permeable area of the optical masking shield, to the light conducting body, and to the display face to illuminate the display face with the shape of the first graphic information, and
the second light ray travels from the second light source to the light conducting body, through the light diffusion area, and to the display face to illuminate the display face with the shape of the second graphic information.

2. The dual graphic label according to claim 1 , wherein the surface of the light conducting body comprises a smooth area that surrounds the light diffusion area.

3. The dual graphic label according to claim 1 , wherein the first light ray and the second light ray illuminate so that the shape of the first graphic information illuminated on a first portion of the display face overlaps with the shape of the second graphic information illuminated on a second portion of the display face.

4. The dual graphic label according to claim 1 , wherein the color of the first light ray and the color of the second light ray are the same.

5. The dual graphic label according to claim 1 , wherein the color of the first light ray and the color of the second light ray are different.

6. The dual graphic label according to claim 1 , wherein the light diffusion area faces the light permeable area.

7. The dual graphic label according to claim 1 , further comprising a controller configured to selectively energize the first light source and selectively energize the second light source.

8. The dual graphic label according to claim 1 , wherein the light diffusion area comprises an etched area.

9. The dual graphic label according to claim 1 , wherein the light diffusion area comprises a light diffusion sheet.

10. The dual graphic label according to claim 1 , wherein the display face comprises a smoked optical element selected from the group of a smoked sheet and a smoked lens.

11. The dual graphic label according to claim 1 , wherein the display face comprises light ray scattering elements.

12. An input element of a control device comprising:
a dual graphic label according to claim 1 ; and
an input element configured to receive a user input.

13. The input element according to claim 12 , wherein the input element comprises a mechanical button arranged inside the dual graphic label and configured to receive an actuation by the user when the display face is pushed.

14. The input element according to claim 12 , wherein the input element comprises a capacitive touch sensor arranged inside the dual graphic label and configured to detect an actuation by the user when the display face is pushed.

15. A faceplate for a vehicle, the faceplate comprising:
at least one input element according to claim 12 ,
wherein the input element comprises:
a dual graphic label configured to selectively display a first graphic information and a second graphic information of the vehicle, and
an input unit configured to receive a user input.

16. A vehicle comprising:
at least two components; and
a faceplate according to claim 15 arranged inside the vehicle, the faceplate having at least one input element,
wherein each at least one input element is configured to:
selectively display a first graphic information of one component of the vehicle and a second graphic information of another component of the vehicle, and
receive a user input regarding the one component.
