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㎡. 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. 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.
