扣除蓝光芯片后,激发电流密度由20 A/cm2升至100 A/cm2时,氮化物黄粉LSN:Ce衰减5.3%,商用同波段铝酸盐黄粉YAG:Ce衰减14%,经计算,氮化物黄粉LSN:Ce比现有材料YAG:Ce的光效衰减幅度减少61.9%;氮化物黄粉LSN:Ce(小粒度)衰减8.1%,商用同波段铝酸盐黄粉YAG:Ce衰减23.2%,经计算,氮化物黄粉LSN:Ce(小粒度)比现有材料YAG:Ce(小粒度)的光效衰减幅度减少65.1%。
After deducting the blue chip, when the excitation current density increases from 20 A / cm2 to 100 a / cm2, the attenuation of nitride yellow powder LSN: CE is 5.3%, and the attenuation of commercial same band aluminate yellow powder YAG: CE is 14%. After calculation, the attenuation amplitude of nitride yellow powder LSN: CE is 61.9% lower than that of existing material YAG: CE; The attenuation of nitride yellow powder LSN: Ce (small particle size) is 8.1%, and the attenuation of commercial same band aluminate yellow powder YAG: CE is 23.2%. After calculation, the attenuation range of light effect of nitride yellow powder LSN: Ce (small particle size) is 65.1% lower than that of existing material YAG: Ce (small particle size).
