광속이란 무엇인가요?

Luminous Flux, also known as luminous power, is a fundamental concept in the lighting industry that quantifies the perceived power of light. It specifically measures the total amount of visible light emitted by a light source or light fitting. Luminous flux is measured in lumens (lm), which is the unit of measurement for this quantity.

주목해야 할 한 가지 중요한 차이점은 광속은 가시광선과 비가시광선을 모두 포함하여 광원에서 방출되는 전자기 복사의 총 전력을 측정하는 복사 광속과 다르다는 점입니다. 광속은 다양한 파장의 빛에 대한 사람의 눈의 다양한 감도를 고려하여 빛의 인지된 밝기를 정확하게 표현합니다.

The human eye’s sensitivity to different wavelengths is described by the luminous function, a mathematical representation that characterizes the eye’s response to each wavelength. By incorporating the luminous function, luminous flux provides a more accurate measurement of the power of 가시광선 as perceived by the human eye.

Luminous flux solely focuses on the total amount of visible light emitted by a source and does not consider the directionality or distribution of the light. Therefore, it provides a measure of the total light output, but not information about how the light is distributed.
