A luminous flux of 1 lm is evenly distributed on a surface of 1 square meter, which produces an illumination of 1 lux. Candlepower (candlepower) is the earliest unit to define luminous intensity, and it is basically abandoned now. At first, a one-foot-long candle was made from one pound of white wax and burned. Surface horizontal radiation is the solar radiation energy projected onto a horizontal surface per unit area per unit time, usually in w/m². Surface horizontal radiation consists of two parts: direct radiation and scattered radiation, that is, surface horizontal radiation = direct radiation + scattered radiation. But in. What is the difference between the light source units lux and lx? Both are lux, the unit of illumination, the universal lux (legal symbol lx) illumination unit, 1 lux is equal to the luminous flux of 1 flow (lumen, lm) evenly distributed on an area of 1㎡.
