Abstract

A warning indicator system for a vehicle side-view mirror includes light sources disposed to emit light in patterns and/or colors visible through a partially light-reflective surface. One or more processors are operatively configured to actuate the light sources in predetermined sequences defining a stealth mode, a pursuit mode, and a traffic advisor mode. The partially light-reflective surface may be a light transmitting substrate having a coating of a reflective substance provided in a thickness allowing at least a partial transmission of light therethrough. The light sources may be printed light-emitting diodes (LEDs). Disposing the light sources in desired patterns to emit desired colors on actuation in a predetermined sequence allows configuring the side mirrors to emit visible light signals indicative of the stealth mode, a pursuit mode, and a traffic advisor mode.

Claims

1. A warning indicator system for a vehicle side-view mirror, comprising:

a transparent conductive layer;

a plurality of printed light-emitting diodes (LEDs) printed on the transparent conductive layer to define a plurality of designs;

one or more photoluminescent portions deposited on the transparent conductive layer to provide, in combination with light emitted by the plurality of printed LEDs, one or more light colors;

a conductive layer disposed to provide an electric charge to the plurality of printed LEDs; and

one or more processors operatively configured to actuate the plurality of printed LEDs in a plurality of predetermined sequences providing, in combination with the one or more photoluminescent portions, a plurality of visible light patterns and/or colors indicating at least a pursuit mode and a traffic advisor mode.

2. The system of claim 1, further including a partially light-reflective surface comprising a light transmitting substrate having a coating of a reflective substance disposed on one side thereof, the coating having a thickness allowing at least a partial transmission of light therethrough.

3. The system of claim 2, wherein the reflective substance comprises a reflective element or compound selected from one of silver, aluminum, indium, chromium, nickel, alloys thereof, or acrylic.

4. The system of claim 2, wherein the plurality of printed LEDs is disposed adjacent the reflective coating whereby at least a portion of the light emitted by the printed LEDs passes through the reflective coating and the light transmitting substrate.

5. The system of claim 4, wherein the one or more photoluminescent portions each comprise a phosphor dye interposed between the reflective coating and the printed LEDs to alter a color of light emitted by the printed LEDs.

6. The system of claim 1, wherein in stealth mode the printed LEDs are not actuated.

7. The system of claim 1, wherein in pursuit mode the one or more processors are configured to actuate in sequence a first printed LED design emitting light of a first color and a second printed LED design emitting light of a second color that is the same as or different from the first color.

8. The system of claim 1, wherein in traffic advisor mode the one or more processors are configured to sequentially actuate one or more printed LED designs to provide a traffic warning.

9. The system of claim 8, wherein the one or more printed LED designs are configured as one or both of a chevron and an arrow.

10. A warning indicator system for a vehicle side-view mirror, comprising:

a light-transmitting substrate having a coating of a reflective substance disposed on one side thereof, the coating having a thickness allowing at least a partial transmission of light therethrough;

a transparent conductive layer;

a plurality of printed light-emitting diodes (LEDs) suspended in a random diode ink and printed on the transparent conductive layer to define a plurality of LED designs;

one or more photoluminescent portions deposited on the transparent conductive layer to provide, in combination with light emitted by the plurality of printed LEDs, one or more light colors;

a conductive ink layer disposed to provide an electric charge to the plurality of printed LEDs; and

one or more processors operatively configured to actuate the plurality of printed LEDs in one or more predetermined sequences to emit light through the one or more photoluminescent layers in a plurality of visible light patterns and/or colors indicating at least a pursuit mode and a traffic advisor mode.

11. The system of claim 10, wherein the reflective substance comprises a reflective element or compound selected from one of silver, aluminum, indium, chromium, nickel, alloys thereof, or acrylic.

12. The system of claim 10, wherein the one or more photoluminescent portions each comprise a phosphor dye interposed between the reflective coating and the printed LEDs to alter a color of light emitted by the printed LEDs.

13. The system of claim 10, further including a stealth mode wherein the printed LEDs are not actuated.

14. The system of claim 10, wherein in pursuit mode the one or more processors are configured to actuate in sequence a first printed LED design emitting light of a first color and a second printed LED design emitting light of a second color that is the same as or different from the first color.

15. The system of claim 10, wherein in traffic advisor mode the one or more processors are configured to sequentially actuate one or more printed LED designs to provide a traffic warning.

16. The system of claim 15, wherein the one or more printed LED designs are configured as one or both of a chevron and an arrow.

17. The system of claim 10, including a housing holding the light-transmitting substrate.

18. A vehicle including a side-view mirror comprising the system of claim 10.
