## Abstract

Disclosed is a device for transporting light, comprising at least two light pipes and at least one connection part, the at least two light pipes and the at least one connection part are molded with same material as a single component, each connection part includes two constitution parts for connecting to two adjacent light pipes, each constitution part has a larger polygonal base, a smaller polygonal base and at least three surfaces connecting the larger polygonal base to the smaller polygonal base, two larger polygonal bases of the two constitution parts connect to the two adjacent light pipes and two smaller polygonal bases of the two constitution bases connect to each other, wherein for each constitution part, at least one surface, whose inner faces incident direction of light within its connecting light pipe, inclines towards the larger polygonal base.

## Claims

### Claim 1

A device for transporting light, comprising at least two light pipes and at least one connection part, the at least two light pipes and the at least one connection part being molded with same material as a single component,
wherein each of the at least one connection part includes two constitution parts for connecting to two adjacent light pipes of the at least two light pipes, each of the two constitution part has a larger polygonal base, a smaller polygonal base, and at least three surfaces connecting the larger polygonal base to the smaller polygonal base,
wherein two larger polygonal bases of the two constitution parts connect to the two adjacent light pipes; and two smaller polygonal bases of the two constitution bases connect to each other,
wherein for each constitution part, at least one surface, whose inside faces incident direction of light within its connecting light pipe, inclines towards the larger polygonal base.

### Claim 2 (depends on 1)

The device of the claim 1, wherein the two constitution parts are symmetric in shape.

### Claim 3 (depends on 1)

The device of the claim 1, wherein surfaces of the at least one connection part are high gloss mirror surfaces.

### Claim 4 (depends on 1)

The device of the claim 1, wherein for each constitution part, all surfaces incline towards the larger polygonal base.

### Claim 5 (depends on 1)

The device of the claim 1, wherein number of the at least one connection part is more than two, and the at least one connection part forms two rows of connection parts.

### Claim 6 (depends on 1)

The device of the claim 1, wherein the larger polygonal base and the smaller polygonal base are rectangles in shape.

### Claim 7 (depends on 1)

The device of the claim 1, wherein the at least two light pipes have a gentle curving bend.

### Claim 8 (depends on 1)

The device of the claim 1, wherein the at least two light pipes have a sharp prismatic fold.

### Claim 9 (depends on 1)

An electronic device, wherein the electronic device has a light source, and light transporting device and an indicator panel, the light transporting device transports light from the light source to the indicator panel, wherein the light transport device has a structure as claimed in claim 1.
