Probation day2

This morning,I learned abt integrating sphere which we can place the lights inside. The point is that we need to adjust the position of the light to make sure the inspection pot is in the shadow.

Along with it , there is another machine, combined with 3 parts,A AC power source, a DC power source and a machine shows the specific data of the inspected light.

Combine with these 2 investments, we can get all specific data of the lights in system. The datas include electric data and light data.
