WebMay 7, 2024 · The light from your torch bounces of different surfaces. Each time it bounces off something, it loses some of its energy and the lost energy gets converted to heat. Thus after multiple collisions, it gets almost completely "absorbed" and all its energy is dissipated as heat. Here by losing energy, I mean that the light's intensity decreases ... WebLEDs are generally spec'ed in Luminous Flux. Luminous Intensity is a whole different thing. But that's not all, Intensity is often confused with Illuminance and Luminance. So we have four methods of measuring the amount of light emitting from an LED. Luminous Flux Luminous Intensity Illuminance Luminance
