ity within the range of visible light output (power). The size range of radiation intensity is less than 1W/sr omitted to tens mW / sr range. With the total light output (lumens / W) divided by input power can be calculated at the light efficiency. Light intensity usually photodetector (PD) were measured. PD flow through the reverse leakage current size and light intensity on top of it is proportional. Therefore, if the LED light with the corresponding PD PD simultaneous measurement of the leaka
