Description
In the study, we analyzed and clarified the effect of green (Y,Gd)BO3:Tb3+
phosphor on chromatic homogeneity and optical performance of multi-chip
white light emitting diodes (MCW-LEDs). Thereby there is a solution to get
the best luminous efficiency. In addition, (Y,Gd)BO3:Tb3+ is known as one
of the factors that has a significant impact on lighting performance, so it
needs to add the (Y,Gd)BO3:Tb3+ phosphor in the structure of LEDs to
combine with the yellow phosphor YAG:Ce3+ to receive the best results.
Therefore, the concentration and size of (Y,Gd)BO3:Tb3+ should be choose
carefully so that the presentation of MCW-LEDs would be more incredible.
The results show that when the concentration of green-emitting
(Y,Gd)BO3:Tb3+ phosphor tends to increase, it also helps the color
homogeneity and the lumen efficiency of MCW-LEDs with the average
correlated color temperature (CCT) of 5600 K-8500 K become better.
