Light assembly, vehicle design element, rear view device and door finisher

1. A system comprising a light assembly for a 360° illumination of a design element, configured for a vehicle design element, comprising:

one or more light pipes, wherein each light pipe comprises a core;

one or more light sources, disposed at least partially within an interior of the system, wherein,

each light source is configured to emit light based on at least receiving electrical power from an electrical power source, and

each light source is arranged adjacent to and directed towards at least one of the one or more light pipes such that the emitted light results in reflected light propagating within the core and diffuse light exiting the one or more light pipes; and

a lens substantially enclosing the interior, the one or more light pipes and the one or more light sources, wherein

the lens, having an inner surface and an outer surface disposed opposite the inner surface, is provided with a continuous transparent and/or translucent coating on the outer surface, and

the one or more light sources receiving electrical power from the electrical power source, the continuous transparent and/or translucent coating is at least partially permeable to at least some of the diffuse light which is passed through the lens;

wherein the continuous transparent and/or translucent coating comprises a metal, an alloy or a conductive metalloid, providing a chromium or chromium-based reflective coating, and

wherein two or more light pipes or two end portions of one light pipe are provided to at least partially overlap, providing at least one region of overlap to substantially close a loop, to provide a homogenous illumination of at least one 360° illumination window when the one or more light sources receive electrical power from the electrical power source.

2. The system of claim 1 , further comprising

a cladding, optics, a plurality of screen printed dots, a paint or a further coating on the one or more light pipes for providing a diffuse, homogenous light output from the one or more light pipes.

3. The system of claim 2 , wherein

each light pipe comprises a cladding surrounding its core such that the emitted light is at least partly reflected by the cladding to propagate within the core,

with the cladding being made from a material selected from the group consisting a fluoropolymer, fluorocarbon polymer and substituted polymer, and

wherein the cladding has a different refractive index compared to the core of each light pipe.

4. The system of claim 1 , wherein each light pipe is flexible and cylindrical.

5. The system of claim 1 , wherein

the light from the one or more light sources is output from the one or more light pipes with a substantially uniform luminance, and

the light from the one or more light pipes is color stable.

6. The system of claim 1 , further comprising:

at least one mask providing the illumination window, with the mask being located between the one or more light pipes and the lens and provided by the continuous transparent and/or translucent coating.

7. The system of claim 6 , wherein the at least one mask provides the illumination window with varying transmission levels, with the window being less transmissive in each region of overlap for providing the homogenous illumination of the illumination window.

8. The system of claim 1 , wherein

the width of the illumination window and mask is not greater than the width of each light pipe, and

the illumination window has an at least partly circular and/or oval shape.

9. The system of claim 1 , further comprising

at least one gasket located at the inner part of the system, between the one or more light pipes and the at least one mask.

10. The system of claim 1 , further comprising

a plurality of small contact areas provided between the one or more light pipes and the coating, a reflector and/or the at least one mask in order to contain light within the core of the one or more light pipes.

11. The system of claim 10 , wherein the plurality of small contact areas is formed

by applying a velvet film,

by providing a velvet surface finish, or

by grain or sand blast of molded or casted parts, the at least one mask, the one or more light pipes, or the at least one reflector.

12. The system of claim 10 , further comprising:

at least one mask providing the illumination window, with the mask being located between the one or more light pipes and the lens and provided by the continuous transparent and/or translucent coating,

wherein the plurality of small contact areas is applied on the mask.

13. The system of claim 10 , wherein

the one or more light sources comprise at least one of an incandescent light source, a light-emitting diode (LEDs), an organic light-emitting diodes (OLED), or a LASER diode, and

the one or more light sources or each light source is located on a circuit board.

14. The system of claim 1 , wherein,

the at least one characteristic of the one or more light pipes is determined by the amount of light pipes, the amount of regions of overlap, the location of each region of overlap, shape and/or dimensions of each region of overlap, or the shape or dimensions of each light pipe, and

the at least one characteristic of the one or more light sources determined by the amount of light sources, the type of each light source, or the location or orientation of each light source.

15. A vehicle design element comprising the system of claim 1 .

16. A rear view device of a vehicle comprising the system of claim 1 .

17. A door finisher for automotive doors comprising the system of claim 1 .

18. The system of claim 1 , wherein a translucency of the continuous transparent and/or translucent coating depends on at least one characteristic of the one or more light pipes or the one or more light sources, and the transparent and/or translucent coating.

19. The system of claim 18 , wherein the at least one characteristic of the transparent and/or translucent coating is determined by at least one of the cladding, the optics, the screen printed dots, or a plurality of contact areas.
