Abstract

A window for a vehicle is provided herein. The window includes a light guide disposed between an outer panel and an inner panel. A light source is optically coupled with the light guide and is configured to direct excitation light towards a luminescent structure. The luminescent structure luminesces in response to receiving the excitation light. A controller is configured to illuminate the light source when an electronic device having an application thereon is in operation.

Claims (31)

1. A window for a vehicle, comprising:

a light guide disposed between an outer panel and an inner panel;

a light source optically coupled with the light guide and configured to direct excitation light towards a luminescent structure, the light source disposed within a seal surrounding the periphery of the outer and inner panels; and

a controller configured to illuminate the light source when an electronic device having an application thereon is in operation; and

first and second light-blocking layers disposed on opposing sides of the light guide, the first light-blocking layer disposed between the light guide and the inner panel and the second light-blocking layer disposed between the light guide and the outer panel wherein the light source emits excitation light in the UV spectrum and the first and second light-blocking layers block light in the UV spectrum from transmission therethrough.

2. The window for a vehicle of claim 1 , wherein the window is a front quarter window.

3. The window for a vehicle of claim 1 , wherein the luminescent structure comprises at least one luminescent material configured to convert the excitation light in a non-visible spectrum received from the light source into a visible, converted light.

4. The window for a vehicle of claim 1 , wherein the luminescent structure defines a first set of indicia and a second set of indicia.

5. The window for a vehicle of claim 4 , wherein the light source is configured to emit varied wavelengths to luminesce the first set of indicia and the second set of indicia independently.

6. The window for a vehicle of claim 1 , further comprising:

an indicia disposed on an interior side of the light guide, the symbol configured to indicate a turn signal status when the turn signal corresponding to a common side of the vehicle of the indicia is initiated.

7. A light system for a vehicle, comprising:

a light source optically coupled with a light guide, the light guide directing light towards a luminescent structure first and second indicia defined by a luminescent structure;

an electronic device in wireless communication with the light source; and

first and second light-blocking layers disposed on opposing sides of the light guide, the first light-blocking layer disposed between the light guide and an inner panel and the second light-blocking layer disposed between the light guide and an outer panel.

8. The light system for a vehicle of claim 7 , wherein the luminescent structure is substantially non-visible in an unexcited state.

9. The light system for a vehicle of claim 8 , wherein the indicia luminesce while the vehicle is being used for commercial purposes.

10. The light system for a vehicle of claim 7 , further comprising:

a seat sensor, wherein the light source is deactivated when the seat sensor detects that a seat of the vehicle is occupied indicating an incoming passenger has entered the vehicle.

11. The light system for a vehicle of claim 10 , further comprising:

a navigation system, wherein the light source is illuminated as the navigation system detects that the vehicle is approaching its destination through a location sensing routine stored in memory of a controller electrically coupled with the light source.

12. The light system for a vehicle of claim 7 , wherein the light guide has a tapered core, wherein a thicker first portion is disposed proximately to the light source and a thinner second portion is disposed further from the light source than the first portion.

13. A light system for a vehicle, comprising:

a light source optically coupled to a light guide;

an indicia defined by a luminescent structure that luminesces in response to receiving excitation light from the light source; a controller configured to activate the light source based on an initiation of an application on an electronic device; and first and second light-blocking layers disposed on opposing sides of the light guide, the first light-blocking layer disposed between the light guide and an inner panel and the second light-blocking layer disposed between the light guide and an outer panel.

14. The light system for a vehicle of claim 13 , wherein the controller includes one or more wireless communication transceivers for altering characteristics of the light source.

15. The light system for a vehicle of claim 14 , wherein the controller associated with the wireless communication transceiver is configured to store information about the electronic device.

16. The light system for a vehicle of claim 13 , wherein the indicia is arranged to indicate one of a left turn and a right turn when in a luminescent state.

17. The light system for a vehicle of claim 13 , wherein the indicia luminesce in a first state when the electronic device performs a first function and in a second state when the electronic device performs a second function.

18. The light system for a vehicle of claim 13 , wherein the luminescent structure is substantially non-visible in an unexcited state.

19. The light system for a vehicle of claim 13 , wherein the light guide includes optics that are configured to direct an excitation light emitted from the light source towards the indicia.
