从From luxury brands to economical models, interior ambient lights are becoming more and more common as a way to adjust the interior atmosphere and improve the grade, and their appearance structures are becoming more and more diversified. Among various types of ambient lights, fiber optic ambient lights that guide light through optical fibers can be said to be the longest and most widely used type. The most classic examples are related models of Mercedes-Benz and BMW.
Mercedes-Benz S-Class Ambient Light
Fiber optic ambient lights are generally installed in relatively hidden areas inside cars. Their thinness and length are the characteristics of this type of product. Therefore, there are relatively strict technical requirements for the luminous uniformity, brightness, and color consistency of optical fiber products. Optical fiber light guide is mainly realized by side emitting light. The advantage of using it is that as a flexible product, it has a high degree of design freedom. It only needs to be cut and processed to the required length, without complex optical design, which reduces early design and mold costs.
Ambient light flexible optical fiber classification:
At present, optical fibers for ambient lighting are divided into two categories: glass optical fibers and high-performance polymer optical fibers. Glass optical fiber light guide strip is a soft light guide composed of many glass optical fibers gathered into a bundle. The polymer light guide strip is made of special acrylic as the inner layer and fluororesin as the outer layer. The two materials are co-extruded. Polymer light guide strips are generally made of transparent and soft materials such as PS, PE, and TPU.

Kuraray's acrylic-based elastomer, KURARITY™, brings an innovative solution to automotive ambient lighting with its excellent transparency and elasticity. This light guide strip product has excellent flexibility and light-guiding properties, and can realize any design you want and the perfect car interior. Single-layer and core-clad elastomeric lightguides can be made from KURARITY™.
The elastic light guide strip made of KURARITY™ material is jointly developed by Kuraray and Fukuvi Chemical Industry Co., LTD.'s professional molding technology. As long as a single-point LED light source is used, a 3-meter-long light guide strip can be illuminated uniformly and guide the light. The main body of the light strip is milky white. By changing the incident light color of different LEDs, different colors of lighting effects can be achieved.
Highlights:This light guide strip, with a length of three meters, can still make the entire strip emit light evenly when a single LED light source enters the light. The shape of the cross-section can be designed according to the user’s application requirements
