“…On another way, the LO of the W_LEDs can be improved significantly by co-doping the green Ce0.67 Tb0.33 MgAl11 O19: Ce, Tb phosphor to the phosphor compounding as shown in [4]. For the purpose of improving the CRI of the W-LEDs, authors in [5,6] proposed to mix the red phosphors to the high CRI multi-chip W-LEDs [7] used green (Ba, Sr) 2SiO4: Eu2+ and red CaAlSiN3: Eu2+ phosphors with various packages W-LEDs to enhance the CRI and [8] showed the missing red component in phosphor-converted W-LEDs for improving its optical properties.…”

In this study, we investigate the effect of concentration of the red Y2O3:Eu3+ phosphor on the Color Rendering Index (CRI), Color Quality Scale (CQS) and Lumen Output (LO) of the 7000K in-cup packaging white LEDs (IPW-LEDs). The physical model of the 7000K IPW-LEDs is conducted by Light Tools software. By varying the concentration of the red phosphor from 0% to 0.36%, we use the Light Tools software to investigate the CRI, CQS, and LO of the 7000K IPW-LEDs. From the research results, it can be observed that the CRI and CQS can be increased to 85 and 71, respectively. However, the LO has a decrease in the increasing trend of the red phosphor concentration. This paper provides the new recommendation for the manufacturing of the IPW-LEDs.
