Abstract

A vehicle lighting assembly is provided herein. The assembly includes a housing including a light permeable portion and a photoluminescent portion. A first light source and a second light source are each located inside the housing. Light emitted from the first light source is outputted from the housing via the light permeable portion and light emitted from the second light source excites the photoluminescent portion to generate a visible light that is outputted from the housing.

Claims (29)

1. A vehicle lighting assembly comprising:

a housing including a light permeable portion and a photoluminescent portion; and

a first light source and a second light source each located inside the housing;

wherein light emitted from the first light source is outputted from the housing via the light permeable portion and light emitted from the second light source excites the photoluminescent portion to generate a visible light that is outputted from the housing;

wherein the housing is divided into a first compartment that is at least partially defined by the light permeable portion and a second compartment that is at least partially defined by the photoluminescent portion; and

wherein the first light source is at least one of a stop light and a rear vehicle light; and wherein the visible light generated by the photoluminescent portion illuminates a license plate.

2. The vehicle lighting assembly of claim 1 , wherein the first light source is located inside the first compartment and the first compartment is configured to internally reflect light such that wayward propagating light contained within the first compartment and originating from the first light source is eventually redirected toward the light permeable portion.

3. The vehicle lighting assembly of claim 1 , wherein the second light source is located inside the second compartment and the photoluminescent portion is substantially Lambertian; and wherein the second compartment is configured to internally reflect light such that wayward propagating light contained within the second compartment and originating from at least one of the second light source and the photoluminescent portion is eventually redirected toward the photoluminescent portion.

4. The vehicle lighting assembly of claim 1 , wherein the light permeable portion is metalized to have a metallic outer appearance while still allowing light emitted from the first light source to be transmitted therethrough.

5. The vehicle lighting assembly of claim 1 , wherein the photoluminescent portion includes a photoluminescent structure coupled to a light dispersing optic; wherein the photoluminescent structure is configured to perform an energy conversion on light emitted from the second light source, thereby producing the visible light; and wherein the visible light has a different wavelength than the light emitted from the second light source.

6. A vehicle lighting assembly configured as an exterior trim piece located on a rear portion of a vehicle and positioned above a license plate, comprising:

a housing including a first compartment having a light permeable portion and a second compartment having a photoluminescent portion; and

a first light source located in the first compartment and a second light source located in the second compartment;

wherein light emitted from the first light source is outputted from the housing via the light permeable portion and light emitted from the second light source excites the photoluminescent portion to generate a visible light that is outputted from the housing;

wherein the first light source is at least one of a stop light and a rear vehicle light; and wherein the visible light generated by the photoluminescent portion illuminates the license plate.

7. The vehicle lighting assembly of claim 6 , wherein the first compartment is configured to internally reflect light such that wayward propagating light contained within the first compartment and originating from the first light source is eventually redirected toward the light permeable portion.

8. The vehicle lighting assembly of claim 6 , wherein the photoluminescent portion is substantially Lambertian; and wherein the second compartment is configured to internally reflect light such that wayward propagating light contained within the second compartment and originating from at least one of the second light source and the photoluminescent portion is eventually redirected toward the photoluminescent portion.

9. The vehicle lighting assembly of claim 6 , wherein the light permeable portion is metalized to have a metallic outer appearance while still allowing light emitted from the first light source to be transmitted therethrough.

10. The vehicle lighting assembly of claim 6 , wherein the photoluminescent portion includes a photoluminescent structure coupled to a light dispersing optic; wherein the photoluminescent structure is configured to perform an energy conversion on light emitted from the second light source, thereby producing the visible light; and wherein the visible light has a different wavelength than the light emitted from the second light source.

11. A high mount stop lamp comprising:

a housing including a light permeable portion and a photoluminescent portion; and

a first light source and a second light source each located inside the housing;

wherein the first light source is a rear-vehicle light and outputs light via the light permeable portion; and

wherein the second light source excites the photoluminescent portion to generate a visible light that illuminates a license plate below the high mount stop lamp.

12. A high mount stop lamp of claim 11 , wherein the housing is divided into a first compartment that is at least partially defined by the light permeable portion and a second compartment that is at least partially defined by the photoluminescent portion.

13. A high mount stop lamp of claim 12 , wherein the first light source is located inside the first compartment and the first compartment is configured to internally reflect light such that wayward propagating light contained within the first compartment and originating from the first light source is eventually redirected toward the light permeable portion.

14. A high mount stop lamp of claim 12 , wherein the second light source is located inside the second compartment and the photoluminescent portion is substantially Lambertian; and wherein the second compartment is configured to internally reflect light such that wayward propagating light contained within the second compartment and originating from at least one of the second light source and the photoluminescent portion is eventually redirected toward the photoluminescent portion.

15. A high mount stop lamp of claim 11 , wherein the light permeable portion is metalized to have a metallic outer appearance while still allowing light emitted from the first light source to be transmitted therethrough.

16. A high mount stop lamp of claim 11 , wherein the photoluminescent portion includes a photoluminescent structure coupled to a light dispersing optic; wherein the photoluminescent structure is configured to perform an energy conversion on light emitted from the second light source, thereby producing the visible light; and wherein the visible light has a different wavelength than the light emitted from the second light source.
