le to prevent the accumulation of the layer structure, the combination of electrons and holes is easy again. This, 1mm square chip pass into the external quantum efficiency of up to 350mA current 65.5%, which leads to 1A current efficiency can be as high as 59%.
By the above method and to reduce the forward voltage technology, hope 1mm square chip in the current density 2A/mm2 luminous efficiency can be achieved when the 150lm / W, luminous flux can be achieved 1000lm. This requires that the in
