Differences between injection moulding light guide and optical fiber light guide
Features on injection moulding light guide
This type of light guide is made by injection moulding PC(polycarbonate) or PMMA(acrylic resin) and so on.
While molding tool per products is needed, it enables to make various designed optical products - long light guide or rounded/square shaped lens and so on according to your needs.
Also you can choose the lighting method like Prism, Brast and Dot. The direction of light distribution and the balance of brightness can change to suit customer's request.
Features on fiber light guide
Generally, fiber light guide is known for its manufacturing way through extrusion molding.
Therefore, the fiber's cross-section shape or its size is limited to a specific type however it doesn't cost so much itinially since there is no need to make tools per products like as injection moulding light guide.
From its flexible material's characterstics, you can bend it freely and the complex optical design is not needed. However it is not possible to illuminate a specific direction only or change the brightness depending on part.
Also you need to consider a structure to fix fiber light guide.
Features on Oshino's Light guide

Key points to choose Light guide
Both fiber light guide and injection moulding light guide would
As for fiber light guide, you can bend freely when you use due to its soft material, however it is necessary to consider the way to fix.
While injection moulding light guide needs initial cost for making mold tool, fiber light guide doen't need it.
However, compared with each of products, injection moulding light guide can be cheaper than fiber light guide in mass production.
Light of fiber light guide is emitted in 360 degree along its fiber.
On the other hand, injection moulding light guide can control its light direction optionally.
It has various illumination methods like Prism, Brast and Dots according to your needs and you can also combine these method.
Prism method : This processing is not suitable for direct illumination since it's easy to see the pattern. But it is appropriate for indirect illumination as it lights brightly.
Blast method : The light amount is smaller than that of Prism method however its pattern is not visible. Besides, light uniformity can be calibrated so it is suitable for direct illumination.
Fiber method : The pattern is not visible and it can be used for direct illumination.
Dot method : This processing is brighter than that of Blast method and its pattern is less visible than that of Prism method.
