Abstract:
    A light flux test device of LED applying narrow optical beam standard light source is prepared as connecting power supply to light source and making light source be lightened, arranging narrow beam standard light source at internal surface of integrating-sphere with no any blocking in sphere, leading light to be tested to micro-multichannel spectrograph by optical fiber passing through narrow light hole then carrying out spectral energy distribution analysis and furthermore calculating out light flux.
