Decorative light guide as high-speed optical interconnect
Aspects of the disclosure include equipment and process schemes for using a plastic decorative light guide of a vehicle as a high-speed optical interconnect. An exemplary method can include forming a decorative light guide from a transparent material. The decorative light guide includes a first insert and a second insert. A light characteristic for optical communication through the decorative light guide is selected based on a current color of the decorative light guide. Light having the light characteristic is injected by a light emitter into the first insert and the light is received by a light receiver from the second insert.
1. A method comprising:
forming a decorative light guide comprising a transparent material, a first insert, and a second insert;
selecting a light characteristic for optical communication through the decorative light guide based on a current color of the decorative light guide;
injecting, by a light emitter, light having the light characteristic into the first insert; and
receiving, by a light receiver, the light from the second insert.
2. The method of claim 1 , wherein the light characteristic comprises at least one of a color, a frequency, a wavelength, and an intensity of the light.
3. The method of claim 2 , wherein the light characteristic is selected such that observable portions of the optical communication through the decorative light guide match the current color of the decorative light guide.
4. The method of claim 2 , wherein the light characteristic is selected from nonvisual light frequencies.
5. The method of claim 2 , wherein the light characteristic is selected from visual light frequencies.
6. The method of claim 1 , wherein the light passes between the first insert and the second insert in a direction parallel to a major surface of the decorative light guide.
7. The method of claim 1 , wherein the first insert and the second insert each comprise a polished transparent material having a surface variation of less than 3 percent.
8. The method of claim 1 , wherein the light emitter defines a portion of a communication hub on the surface of the first insert and the light receiver defines a portion of a control object on the surface of the second insert.
9. The method of claim 8 , wherein the control object comprises one or more of a camera, a display, a rain sensor, an air quality sensor, a driver monitor, a passenger monitor, and a microphone.
10. The method of claim 8 , wherein the communication hub negotiates with the control object to communicate through the decorative light guide using light having the selected light characteristic.
11. A system for providing a high-speed optical interconnect in a vehicle, the system comprising:
a decorative light guide;
a first insert in a first region of the decorative light guide;
a second insert in a second region of the decorative light guide;
a processor configured to select a light characteristic for optical communication through the decorative light guide based on a current color of the decorative light guide;
a light emitter positioned on a surface of the first insert, the light emitter configured to inject light having the light characteristic into the first insert; and
a light receiver positioned on a surface of the second insert, the light receiver configured to receive the light at the surface of the second insert.
12. The system of claim 11 , wherein the light characteristic comprises at least one of a color, a frequency, a wavelength, and an intensity of the light.
13. The system of claim 12 , wherein the light characteristic is selected such that observable portions of the optical communication through the decorative light guide match the current color of the decorative light guide.
14. The system of claim 12 , wherein the light characteristic is selected from nonvisual light frequencies.
15. The system of claim 12 , wherein the light characteristic is selected from visual light frequencies.
16. The system of claim 11 , wherein the light passes between the first insert and the second insert in a direction parallel to a major surface of the decorative light guide.
17. The system of claim 11 , wherein the first insert and the second insert each comprise a polished transparent material having a surface variation of less than 3 percent.
18. The system of claim 11 , wherein the light emitter defines a portion of a communication hub on the surface of the first insert and the light receiver defines a portion of a control object on the surface of the second insert.
19. The system of claim 18 , wherein the control object comprises one or more of a camera, a display, a rain sensor, an air quality sensor, a driver monitor, a passenger monitor, and a microphone.
20. The system of claim 18 , wherein the communication hub negotiates with the control object to communicate through the decorative light guide using light having the selected light characteristic.
