1. a light source aging test measuring device, comprise testing laboratory (1), measured light (2) and sampler (4) is provided with in testing laboratory (1), it is characterized in that, reference source (6) is provided with in testing laboratory (1), described reference source (6) is arranged on the one or more positions in testing laboratory (1), or described reference source (6) is arranged on testing laboratory (1) outward, by lightguide (15), the light that reference source (6) sends is imported in testing laboratory (1);

  • Described measured light (2) and reference source (6) are electrically connected with program-controlled power supply (3), described program-controlled power supply (3) controls measured light (2) and is lit in the ageing step, the ageing step that described reference source (6) is lit at measured light (2) is in OFF state, and the compare and measure stage of reference source (6) before and after measured light (2) ageing step lights;

    The light that described sampler (4) reception measured light (2) and reference source (6) send, and by optical signal transmission in coupled photometric meter (5), the light signal of reception is input in the host computer (12) be connected electrically by described photometric meter (5), host computer (12) stores and analyzes the optical parametric of measured light (2) and reference source (6), obtains the coefficient of comparisons for correcting measured light (2) measurement result.
