JRC REFLEX

Retroreflection is a term used to describe the amount of the light reflected from a retroreflective surface or material.

Retroreflection is the same as REFLECTIVITY and also REFLECTANCE The light is measured in Candela Lux per square meter. Retroreflection at specified entrance angles and observation angles are an important part of specifications

Glossary

Angularity

Refers to the degree to which a reflectivesheeting reflects light.

Candela (CD)

The international system (SI) unit of luninous intensity. It is approximately the luminous intensity of a candle flame.

Coefficient of retroflection

Quotient of the coefficient of luminous intensity (R) of a plane retroreflecting surface to its area expressed in candela per lux per square metre (dc/lx/m2) R = R/A

Cube corner reflection

Is the use of cube corner elements to reflect light. Cube corner elements are built into retroreflective sheeting.

Entrance angle

Is the angle formed between a light beam striking a surface at some point and a line perpendicular to the surface at the same point.

Microprismatic

Is the use of cube corner elements to reflect light. Cube corner elements are built into retroreflective sheeting.

Pantone matching system (PMS)

Is an international printing color language providing an accurate method for the selection of color.

Prismatic

Is the use of cube corner elements to reflect light. Cube corner elements are built into retroreflective sheeting.

Retroreflectance

Is a term used to describe the amount of light reflected from a retroreflective surface or material. This light is measured in lux per square meter.Retroreflectance at specified entrance angles and observation angles are an important part of specifications.
