How Does Retro Reflective Tape Work ?

Many people in life wonder how retro reflective tape can reflect light, because it does not look eye-catching and will reflect very eye-catching light when illuminated. The reflective part of the reflective tape is made of glass beads with high refractive index. The reflective glass beads are the core material for the production of reflective fabrics, reflective films, reflective coatings and other new optical functional composite materials. It has the characteristics of returning to light, and This produces a strong retro-reflective effect and does not require an external power source. It can be widely used in roads, ports, mines, fire protection, traffic safety and other fields. As a safety sign, it greatly improves people's safety and reliability.

At present, glass beads have several specifications with refractive index greater than N1.9, N1.93, and greater than N2.2. The inspection range is 150 mesh to 500 mesh (available in grades). The product has good fluidity, good color, and high spherical shape. Transparency is higher than 95%.

Principle of reflection:

Reflective material products use high-refractive-index glass beads with aluminum on the rear surface as the retroreflector, which has extremely strong retroreflection performance, and can reflect 85% of the light directly back to the light source. The reflective brightness caused by retroreflection, The driver can clearly see pedestrians or obstructive targets at night with light sources or under poor vision, ensuring the safety of both parties.

The last thing to remember is that the more concentrated the beam, the more your eyes need to be aligned with the light source, so that when the light is reflected back, you can see it. As you approach the traffic lights, you will notice that the tape no longer lights up. This is because the angle from the light to the tape to your eyes becomes too large. In other words, the relationship between light and eyes can make a big difference. If you put the lamp close to the head, the reflectance will not change when you get close. Kunshan Yuhuan reflective tape uses advanced processing machines and strict quality control. There are special quality inspectors for quality inspection, and it can be shipped only after it is qualified. Provide you with a large amount of high-quality reflective tape.
