전력 에서 와트(W) to illum에서ance in lux (lx) calculator and how to calculate.
입력하세요 전력 에서 watts, luminous efficacy in lumens per watt, surface area in square feet / meters or spherical radius in feet / meters and press the 계산 button to get the illum에서ance in lux:
* the predef에서ed luminous efficacy values are typical / average values.
The illum에서ance Ev 에서 lux (lx) is equal to 10.76391 times the 전력 P in 와트(W), times the luminous efficacy η 에서 lumens per watt (lm/W) divided by the surface area A 에서 square feet (ft2)로 나눈 값과 같습니다:
Ev(lx) = 10.76391 × P(W) × η(lm/W) / A(ft2)
The illum에서ance Ev 에서 lux (lx) is equal to the 전력 P in 와트(W), times the luminous efficacy η 에서 lumens per watt (lm/W) divided by the surface area A 에서 square meters (m2)로 나눈 값과 같습니다:
Ev(lx) = P(W) × η(lm/W) / A(m2)
