Light Guiding Bar is a unique Light Guide
product made by Fukuvi, a professional
resin molding company.
The light guiding bar is Fukuvi's original light guiding product, made of transparent resin, that directs the light of an LED source and produces a beautiful and elegant result.
It has excellent heat resistance, flexibility, light uniformity, and can be used in a variety of applications such as automobiles, home appliances, robotics, medical equipment , etc.
It has a two-layer structure that uses acrylic resin for the core layer and a low refractive index material for the cladding layer and uses the difference in refractive index between them to guide the light.
Uniform luminescence of up to 2.5m can be achieved. (When the light source enters from both ends, it conducts light up to 5m.)
In addition to lighting up the entire light guiding bar, it is also possible to achieve localized illumination depending on the design of the surface layer.
We offer a wide variety of thicknesses, as well as, a "hard type" and a "soft type" guiding bar, which can be mixed and matched with the offered optical characteristics and combined to meet your needs.
Since the light of the LED is projected as a linear light source, it is possible to create a beautiful glow along the length of the bar.
Utilizing Fukuvi Chemical's strength in profile extrusion molding technology, we can mold a variety of light guiding bars, including not only circular shapes but also complex shapes and those with reflective layers and directional light emission.
When compared to other products that aim to illuminate along a certain length, such as the more common LED tape, which requires complete replacement once an LED fails along its span, our light guiding bar utilizes only one LED light source, which is at the beginning of the line, and only the faulty light source needs to be replaced, making maintenance easier.
Using acrylic resin with excellent transparency as the core layer, we have developed specifications for three variants with different features.
Soft high-brightness type with excellent luminescence, flexibility and impact resistance
Soft light emission uniform type that suppresses chromaticity changes in white light and has flexibility and impact resistance
Hard type with excellent durability and light emission uniformity
By using a high performance resin for the cladding layer, excellent durability (weather resistance, chemical resistance, and stain resistance) has been achieved.

Meeting to discuss specifications
Our representative (or engineer, as the case may be) will ask you about the details of your request and determine whether our existing product lineup can meet your needs.
Selection from our existing products
Special Order
If there is nothing in our existing lineup that matches your needs, we will create a special order. In some cases, a new mold may be required. We will provide design drawings + mold cost + product price.
Quotation
Estimate (including mold cost)
Ordering of molds - Provision of prototypes
Once the new design is decided on, the mold will be manufactured. It takes about 2 months from mold fabrication to prototype shipment.
Approval of prototype
The customer evaluates the prototype, and if it is acceptable, the initial production will be started after concluding the delivery specifications.
Ordering
Shipment and Delivery
We have developed extrusion molded products with a metal-like texture by using our original metallic tone resin. Standard and custom colors are available. Please feel free to contact us.
