 the detection mechanism of the actual some non- integrating sphere probe frosted films, some   LED Bulb  with frosted Flakes , but whether there is selective absorption or absorption spectrum size is unknown ; various testing organizations within the sphere of the actual location of the different probes ,

 some flat, some Goals outer recess ; but the test results show that the front position of the probe type , and non -destructive optical 10mm twisted little effect on the measurement results .

② Pre-Shot Stabilization: warm-up with electronic instruments need stability , like the photoelectric spectroscopy system should also be used with the measured light flux quite light for 20 minutes of Pre-shot stability, calibration and measurement was carried out , the actual this operation may be performed a lot of people did not pay attention .

( 8 ) the position of the temperature probe

  LED Flexi Strip

Temperature probe should avoid direct sunlight , close to the mask at the back of the block . And the distance from the measured light uniform , i.e., center of the sphere of radius R, the distance to be 1 /3. For temperature -sensitive such as traditional fluorescent lamps , energy saving lamps and a variety of LED lights, ambient temperature measurement requirements of 25 ℃ (± 1 ℃).
