Increasing LED lights brightness can be broadly divided into two types, one is to increase chip itself, the amount of light emitted; Another method is the effective use of the light generated by the chip, increasing the exposure of the light irradiation to the expected direction. The former is trying to improve the luminous efficiency of the chip active layer, as well as to improve the chip shape to increase the external light extraction efficiency, or chip, large-scale use of high current de...Continue reading
