luminous flux output 输出光通量
High-purity imported aluminum reflector is used to effectively improve the reflectivity and ensure the output of luminous flux.
采用高纯度进口铝反射罩，有效提高了反射率，并确保了光通量的输出。
At the same time, the leakage current was minimum and light output was maximum. Then the leakage current increased and luminous flux reduced for green LED.
同时，两种LED的反向漏电也最小、光通量最大，随后绿光led的反向漏电增加较快且光通量衰减较快。
