radiant flux
Radiant flux, also known as radiant power, refers to the total amount of energy emitted by a light source per unit of time. It is measured in watts (W) and represents the flow of radiant energy, which can include visible light, infrared, and ultraviolet radiation. Understanding radiant flux is essential in fields like photometry and optics, as it helps quantify how much light is produced by a source.
In practical applications, radiant flux is crucial for designing lighting systems, evaluating the performance of LEDs, and assessing the energy output of solar panels. By measuring radiant flux, engineers and scientists can optimize light sources for efficiency and effectiveness in various environments.
