Abstract:
The present invention provides an instrument and method for measuring total luminous flux of luminous elements, which forms an approximately uniform spatial intensity distribution by simultaneously lighting a plurality of luminous elements for measurement in an integrating sphere when comparing a total luminous flux standard lamp with the luminous elements to measure the total luminous flux of the luminous elements, thus not requiring spatial mismatch error correction.
