Any test circuit corresponding to that of figure 1 can be used to make the measurement of EBLF The luminous flux of a lamp is usually measured with an integrating photometer For ratio measurements of lumious fluxes a suitable illuminance meter is sufficient as there is a close ralationship between luminous flux and illumination at a fixed point

燈泡的光通量測量通常都是用一體式光度計來測量. 對於光通量測量的比率, 合適的照度計即可測量, 因為光通量和照度在某一點上來說有著極為相近的關系. |
