Furthermore, the theory foundation and analysis method are put forward. We use optical extent to analyze the system. The change of optical extent, caused by arc length of light source and reflective bowl attached the light source, is analyzed in detail. Moreover, the light output by optical extent curve of light source with reflector is measured by experiment. Base on the analysis and experiment, four hypothesis are put forward to construct the true model of light source.
