Abstract

A light assembly is provided that includes a holder and multiple light pipes. The holder extends along a longitudinal axis between a first end and a second end. The holder includes multiple ridges that spiral around the longitudinal axis. The holder includes multiple channels. Each channel is defined between two of the ridges. The light pipes each include a light transmissive interior region. Each of the light pipes is disposed in one of the channels of the holder. The light pipes each have an attachment end that is configured to receive light from a light source. Each light pipe is further configured to transmit the light through the interior region for at least a length of the light pipe.

First claim

What is claimed is:

1. A light assembly comprising:
a holder extending along a longitudinal axis between a first end and a second end, the holder including multiple ridges that spiral around the longitudinal axis, the holder including multiple channels, each channel defined between two of the ridges;
multiple light pipes that each include a light transmissive interior region, each of the light pipes disposed in one of the channels of the holder, the light pipes each having an attachment end that is configured to receive light from a light source, each light pipe further configured to transmit the light through the interior region for at least a length of the light pipe before the light is emitted from the light pipe; and
a lens extending parallel to the longitudinal axis of the holder and configured to receive at least some of the light emitted from the light pipe, the lens formed of a light transmissive material such that the light from the light pipes that impinges upon the lens is transmitted through the lens and illuminates a surrounding environment.

2. The light assembly of claim 1 , wherein the light assembly includes at least three light pipes that wrap around the holder in a repeating sequence, the light pipes each configured to emit light from the respective interior region to illuminate a corresponding axial zone perceivable by an observer, the axial zones aligned parallel to the longitudinal axis in the repeating sequence.

3. The light assembly of claim 2 , wherein the repeating sequence includes a repeating pattern of a first light pipe, a second light pipe, and a third light pipe such that the second light pipe is between the first and third light pipes, the light emitted from the second light pipe illuminating a second axial zone that is between a first axial zone that is illuminated by light emitted from the first light pipe and a third axial zone that is illuminated by light emitted from the third light pipe.

4. The light assembly of claim 1 , wherein the lens receives light from each of the light pipes at different locations along a length of the lens.

5. The light assembly of claim 1 , further comprising one or more light sources optically coupled to the attachment ends of the light pipes, the one or more light sources configured to generate light at different times such that the corresponding light pipes receive light at different times and emit the light at different axial locations along the longitudinal axis of the holder to create a dynamic lighting effect that provides an appearance of a single light source physically moving parallel to the longitudinal axis of the holder.

6. The light assembly of claim 1 , wherein the ridges spiral around the longitudinal axis of the holder with a uniform profile, the multiple light pipes received in the channels being equally spaced apart from each other along the length of the holder between the first and second ends.

7. The light assembly of claim 1 , wherein each of the ridges extends between adjacent light pipes and prohibits light emitted from one of the light pipes from being received by an adjacent light pipe.

8. The light assembly of claim 1 , wherein the light pipes are fiber optic cables, the light transmissive interior region of each of the light pipes including multiple glass strands commonly held within a cladding layer.

9. The light assembly of claim 1 , wherein the light pipes are composed of a solid acrylic material.

10. A light assembly comprising:
a holder extending along a longitudinal axis between a first end and a second end, the holder including multiple ridges that spiral around the longitudinal axis, the holder including multiple channels, each channel defined between two of the ridges;
multiple light pipes that each include a light transmissive interior region, each of the light pipes disposed in one of the channels of the holder, the light pipes each having an attachment end that is configured to receive light from a light source, each light pipe further configured to transmit the light through the interior region for at least a length of the light pipe before the light is emitted from the light pipe; and
a shroud surrounding a first portion of a perimeter of the light pipes and the holder along a length of the holder, the shroud configured to at least one of absorb or reflect light emitted from the light pipes along the first portion of the perimeter that impinges on the shroud, wherein light emitted from the light pipes along a remaining portion of the perimeter not surrounded by the shroud is not absorbed or reflected by the shroud and illuminates a surrounding environment outside of the shroud.

11. The light assembly of claim 1 , wherein the ridges extend radially from a center point of the holder, the thickness of the ridges increasing with increasing radial distance from the center point such that the thickness at an outer edge of each ridge is greater than at an inner region of the respective ridge more proximate to the center point, the channels defined between the ridges having a smaller diameter between the outer edges of the ridges than between the inner regions of the ridges.

12. A light assembly comprising:
a connector that includes a housing and multiple light sources held within the housing;
multiple light pipes that are each elongated between an attachment end and a distal end, the attachment end of each light pipe being coupled to the housing and optically coupled to one of the light sources, the light emitted by the light sources being received by the corresponding light pipe at the attachment end and transmitted through the light pipe via internal reflection towards the distal end; and
a holder that is elongated along a longitudinal axis between a first end and a second end, the holder having multiple ridges extend radially outward from a center point of the holder, the ridges spiraling around the longitudinal axis along the length of the holder between the first and second ends, the holder including multiple channels that are each defined between two of the ridges, each channel configured to hold one of the light pipes therein.

13. The light assembly of claim 12 , wherein the light assembly includes three light pipes that wrap around the holder in a repeating sequence, the repeating sequence including a repeating pattern of a first light pipe, a second light pipe, and a third light pipe such that the second light pipe is between the first and third light pipes, light emitted from the three light pipes illuminating corresponding axial zones perceivable by an observer, the axial zones aligned parallel to the longitudinal axis in the repeating sequence such that the light emitted from the second light pipe illuminates a second axial zone that is between a first axial zone illuminated by light emitted from the first light pipe and a third axial zone illuminated by light emitted from the third light pipe.

14. The light assembly of claim 13 , wherein the light sources are configured to generate light at least one of at different times or of different colors or intensities such that the axial zones are illuminated at least one of at different times or by different colors or intensities of light, creating a dynamic lighting effect.

15. The light assembly of claim 12 , further comprising a lens extending parallel to the longitudinal axis of the holder, the lens formed of a light transmissive material such that light emitted from the light pipes that impinges upon the lens is transmitted through the lens and illuminates a region of a surrounding environment.

16. The light assembly of claim 12 , wherein the ridges
