The entrance angle, in the context of reflective tape, is a crucial factor that determines the effectiveness of the tape in reflecting light. It refers to the angle at which a beam of light enters the tape. The entrance angle is calculated with a perpendicular line from the tape being considered as “0” degrees.
When light hits the reflective tape at a perfect right angle, like the shape of a T, the entrance angle is considered to be “0” degrees. As the angle deviates from the perpendicular, the entrance angle increases or decreases accordingly. For example, if the light hits the tape at a slanted angle, the entrance angle will be greater than “0” degrees.
The entrance angle is significant because it directly affects the tape’s ability to reflect light back to its source. When the entrance angle is closer to perpendicular, the tape reflects light more efficiently, resulting in better visibility. On the other hand, if the entrance angle deviates significantly from perpendicular, the tape’s reflective performance may be compromised, leading to reduced visibility.
Understanding the entrance angle is crucial when selecting and installing reflective tape, as it ensures optimal performance in various lighting conditions. By considering the entrance angle, one can choose the appropriate tape that will provide maximum reflectivity at the desired viewing angles.
