Noun1.luminous flux unit- a measure of luminous flux per unit area light unit- a measure of the visible electromagnetic radiation lm,lumen- a unit of luminous flux equal to the amount of light given out through a solid angle of 1 steradian by a point source of 1 candela intensity radiatin...
Consequently, the synthesized beam can be projected almost in the same direction and the light beams can be synthesized without losing the light quantity independently of a polarized state.吉田 和司
The SI unit of luminous flux is the lumen (lm). The lumen is defined in relation to the candela which is the unit of luminous intensity as 1 lm = 1 cd ⋅ sr That is, when the luminous angle of a light source is one solid angle and the luminous flux is 1 lumen, its luminous ...
The SI unit of luminous flux is the lumen (lm). 流明(lumen,符号lm)是 光通量 的国际单位。 ParaCrawl Corpus It is therefore the only value that gives the actual luminous flux of a light source reliably. 因此,流明是表示光源实际光通量的唯一可靠数值。 ParaCrawl Corpus Free Online Onlin...
