The second experiment is to fabricate white light LED from red and green phosphors pumped by blue light LED. The blue light LED we used in our experiment has the wavelength range between 450 and 452.5 nm, and the chip size is 17 mil *14 mil. There are two kinds white light LED we fabricated in the experiment. There are three blue light LED chips bonded in single package of both kinds package. The different of the both packages is mixed phosphor of encapsulation. One of the experimental devices was encapsulated YAG phosphor mixed silicone to fabricate white light. The other is red and green phosphor mixed encapsulation. The compared and focused parameter was luminous efficiency. YAG phosphor pumped white light has the luminous efficiency 72 lm/W, CRI 70, CIE(0.32, 0.33), CCT 5622°K at the operating current 60mA. On another hand, red and green phosphor pumped white light LED has the luminous efficiency 55 lm/W, CRI 90, CIE(0.31, 0.32), CCT 6479°K at the operating current 60mA. We fabricated the red and green phosphor pumped white light LED, and proved that it could has much higher CRI under similar compared conditions, CIE xy and CCT.
