Kind Code:
A
Abstract:
To provide a connection structure capable of connecting a plurality of light guide bodies in portions other than end faces.SOLUTION: A first light guide body 20 and a second light guide body 30 respectively comprise refraction control parts 27 and 37 for emitting propagated light in a light emission direction L in a portion of side faces. The first light guide body 20 comprises a first connection part 22 which is bent in a first direction as being closer to one end, and the second light guide body 30 comprises a second connection part 32 which is bent in a second direction as being closer to the other end. The first light guide body 20 and the second light guide body 30 are connected in the first connection part 22 and the second connection part 32 in such a manner that the first connection part 22 is disposed at a side of the first direction and that the second connection part 32 is disposed at a side of the second direction. A connection plane 42 is configured in the light emission direction L to form an angle for suppressing leakage of light propagated inside of the first light guide body 20 and the second light guide body 30 with respect to a length direction.SELECTED DRAWING: Figure 3
