Ba[MgSUB2/SUBAlSUB2/SUBNSUB4/SUB]EuSUP2+/SUP phosphor for enhancing the optical quality of the 6600K CPW-LEDs

摘要

Compared with conventional lamps, LED-based light sources have a superior lifetime,efficiency, and reliability, which promise significant reductions in power consumption andpollution from fossil fuel power plants. In this paper, we proposed and investigated theeffect of the concentration of Ba[Mg2Al2N4]Eu2+conversion phosphor on the CCTdeviation (D-CCT) and lumen output (LO) of the 6600 K conformal-packaging whiteLEDs (CPW-LEDs). For this purpose, we used the Light Tools and Mat Lab software toinvestigate this problem. From the research results, we can state that the concentration ofthe red phosphor has a significant effect on the optical quality of the 6600 K CPW-LEDs.The D-CCT can be decreased from 4700K to 2500K, and the LO can be increased from600 lm. to 1200 lm. This research can provide the new recommendation for LEDs industryat this time.
