In the use of the LED, people pay attention to the maximum luminous power of the LED, namely, the energy saving effect of the LED. When the energy-saving effect of the LED is judged by the traditional scheme, the average illumination, the illumination uniformity and the like of the LED are generally measured, and then the luminous power and the energy-saving effect of the LED are judged according to the measurement result. However, the method does not fully consider the properties of the LED, which easily causes the problem of large error of the judgment result of the energy-saving effect of the LED. Therefore, the conventional scheme has the problem of large error when judging the energy-saving effect of the LED.
