What is brilliance of light?

The brilliance of light, also known as luminance or brightness, is a measure of the intensity of light emitted or reflected from a surface. It is the amount of light that is visible to the human eye and is determined by the properties of the light source and the reflective or transmissive properties of the surface.

The unit of measurement for brilliance is the candela per square meter (cd/m²), which represents the amount of light that falls on one square meter of surface. A higher value of brilliance means that the surface appears brighter and emits more light.

The brightness of light can vary based on several factors such as the distance between the source and the surface, the angle of incidence, the reflection coefficient (the proportion of light reflected by the surface), and the color and temperature of the light source.

The concept of brilliance is important in various fields such as optics, lighting design, photography, and display technology. It plays a crucial role in determining the visual quality of an image or a display and has applications in areas such as entertainment, art, architecture and more.
