60W LED corn lamp lighting
By the formula of L = d2Φ/(dA·cosθ·dΩ) defined amount, unit of candela per square metre (CD/m2).
dΦ - from a given point of yuan transmission and contain the given direction within the solid Angle d Ω spread of luminous flux (lm);
dA - including a given point of the beam cross-sectional area (㎡);
θ -- the Angle between the normal of the beam cross section and the direction of the beam.
The intensity of illumination refers to the amount of energy in the unit area that receives the visible light, or as the illumination, the unit Lux (Lux or Lx).A physical term used to indicate the intensity of light and the amount of surface area being illuminated.
Calculation method for the luminous flux incident on the bin contains point d Φ divided by the surface of the shang dA yuan area, unit for lux(lx)，1lx=1lx/㎡.
