Illuminating running board
A running board of a vehicle is provided herein. The running board includes a housing and a light-producing assembly disposed inside the housing. The light-producing assembly includes a plurality of light sources and a photoluminescent structure configured to luminesce in response to excitation by light emitted from the plurality of light sources, wherein luminescent light escapes the housing via a first light permeable portion and a second light permeable portion.
1. A running board of a vehicle, comprising:
a housing;
a light-producing assembly disposed inside the housing and comprising:
a light source; and
a photoluminescent structure configured to luminesce in response to excitation by light emitted from the light source, wherein luminescent light escapes the housing via a first light permeable portion and a second light permeable portion, wherein the first light permeable portion comprises a bottom portion of the housing and the second light permeable portion comprises a side portion of the housing, wherein light escaping the housing via the bottom portion illuminates a ground area near the vehicle, and wherein light escaping the housing via the side portion provides ambient light.
2. The running board of claim 1 , wherein the housing defines an edge of the running board.
3. The running board of claim 1 , wherein the light-producing assembly is arranged over one of a curved surface and a linear surface.
4. The running board of claim 1 , wherein the light source comprise a printed LED arrangement.
5. The running board of claim 1 , wherein the housing further comprises a light blocking portion disposed between the first and second light permeable portions.
6. The running board of claim 5 , wherein the light blocking portion is configured to internally reflect light inside the housing.
7. The running board of claim 6 , wherein the first light permeable portion, the second light permeable portion, and the light blocking portion each extend the length of the running board.
8. A running board of a vehicle, comprising:
a housing defining an edge of the running board;
a light-producing assembly disposed inside the housing and comprising:
a light source; and
a photoluminescent structure configured to luminesce in response to excitation by light emitted from the light source, wherein luminescent light escapes the housing via a light permeable side portion and a separately disposed light permeable bottom portion to illuminate a ground area near the vehicle.
9. The running board of claim 8 , wherein the light-producing assembly is arranged over one of a curved surface and a linear surface.
10. The running board of claim 8 , wherein the light source comprises a printed LED arrangement.
11. The running board of claim 8 , wherein the housing further comprises a light blocking portion disposed between the side portion and the bottom portion.
12. The running board of claim 8 , wherein luminescent light also escapes the housing via the light permeable side portion to provide ambient light.
13. The running board of claim 8 , wherein portions of the housing are configured to at least one of internally reflect light and have an outward metallic appearance.
14. A running board of a vehicle, comprising:
a housing;
a light-producing assembly disposed inside the housing and comprising:
a light source; and
a photoluminescent structure configured to luminesce in response to excitation by light emitted from the light source, wherein luminescent light escapes the housing via a light permeable side portion to provide ambient light and via a light permeable bottom portion to illuminate a ground area near the vehicle, wherein the light permeable side portion and the light permeable bottom portion are separated by a light blocking portion.
15. The running board of claim 14 , wherein the housing defines an edge of the running board.
16. The running board of claim 14 , wherein the light-producing assembly is arranged over one of a curved surface and a linear surface.
17. The running board of claim 14 , wherein the light source comprises a printed LED arrangement.
18. The running board of claim 14 , wherein portions of the housing are configured to internally reflect light propagating inside the housing.
19. The running board of claim 14 , wherein portions of the housing are configured to have a metallic appearance.
