Retroreflection occurs when surfaces return the directed light to its source. This is why retroreflective materials appear brightest to observers located near the light source – a driver and the vehicle headlights, for example, The report the pedestrian who wears reflective garment can be protected by car accidents about 90% proves the importance of the reflective effectiveness.
Each glass bead works as follows : An incoming light beam refracts as it passes through the front surface of the glass bead and reflected off a mirrored surface behind the bead again. The beam then passes back through the front surface, and returns toward the light sources.
Cube Corner Reflection
Cube corners are retro-reflective lens elements like glass beads. Each?cube?corner has three mutually perpendicular refractive surfaces. An incidental light ray is refracted on each of the three surfaces and returned to its source parallel to its initial direction. It functions like a ball bounced into the corner of a room.
