Planar optical member and daylighting device

A planar optical member comprising:

• a planar structure body comprising:
• a plurality of linear bodies formed of optically transparent materials which are arrayed substantially in parallel, and
• a plurality of binding members which are arranged in a direction which intersects with the plurality of the linear bodies and which bind the plurality of the linear bodies in a state of being arrayed substantially in parallel, the plurality of binding members fixing the plurality of linear bodies such that the plurality of linear bodies do not individually rotate,
• wherein the linear bodies comprise
• a reflective surface, which reflects light which is incident to the linear bodies along a direction which intersects with a length direction of the linear body, and
• a refractive surface which refracts the light,
• in at least a part of the planar structure body,
• orientations of the reflective surfaces of at least some of the linear bodies out of the plurality of the linear bodies substantially match, and
• orientations of the refractive surfaces of at least some of the linear bodies out of the plurality of the linear bodies substantially match, and
• some of the linear bodies out of the plurality of the linear bodies comprise a linking section configured to integrally links the linear bodies which are adjacent to each other.

A daylighting device comprising:

• a planar optical member;
• and
• a support member which supports the planar optical member,
• wherein external light is taken in through the planar optical member,
• wherein the planar optical member comprises:
• a planar structure body which comprises:
• a plurality of linear bodies formed of optically transparent materials which are arrayed substantially in parallel, and
• a plurality of binding members which are arranged in a direction which intersects with the plurality of the linear bodies and which bind the plurality of the linear bodies in a state of being arrayed substantially in parallel, the plurality of binding members fixing the plurality of linear bodies such that the plurality of linear bodies do not individually rotate,
• wherein the linear bodies comprise
• a reflective surface, which reflects light which is incident to the linear bodies along a direction which intersects with a length direction of the linear body, and
• a refractive surface which refracts the light,
• in at least a part of the planar structure body,
• orientations of the reflective surfaces of at least some of the linear bodies out of the plurality of the linear bodies substantially match, and
• orientations of the refractive surfaces of at least some of the linear bodies out of the plurality of the linear bodies substantially match.
