LIGHT FLUX Meaning and
Definition
-
Light flux is a term used in the field of physics to describe the rate at which light energy flows through a given surface area. It is a measure of the total quantity of light passing through a point in a specific amount of time. The unit of measurement for light flux is the lumen (lm).
Light flux is determined by considering both the intensity and the surface area over which the light is spread. Intensity refers to the brightness of the light source, while surface area refers to the size of the area on which the light falls. Thus, light flux can be understood as the product of intensity and surface area.
Light flux is an important parameter used in various applications, such as illuminating systems and radiometry. It is particularly crucial in lighting design, as it helps determine the amount of light required to illuminate a given space or object effectively. In this context, light flux is often referred to as luminous flux.
Moreover, light flux is used to calculate other photometric quantities, such as luminous intensity and luminance. These measures help provide a more comprehensive understanding of the light characteristics and enable accurate comparisons between different light sources. Overall, light flux plays a fundamental role in the study of light energy and its practical applications.

Etymology of LIGHT FLUX
The word "light" comes from Old English "lēoht" which means brightness, shining, or illumination. It is related to the Old High German "liuhta" and Old Norse "ljóss".
The word "flux" comes from the Latin "fluxus" which means flow or a state of continual change or transition. It is derived from the verb "fluere" meaning to flow. "Flux" was originally used in English to refer to the flow or discharge of natural substances like water or bodily fluids.
When the terms "light" and "flux" are combined, "light flux" refers to the flow or circulation of light energy or the rate at which light is radiated or emitted from a source.
