Patterned phosphor-in-glass films with efficient thermal management for high-power laser projection display

Recently, high-performance color converters excitable by blue laser diode (LD) have been sprung up for projection display. However, thermal accumulation effect of is a non-negligible problem under high-power LD irradiation. Herein, we developed novel opto-functional composite (patterned CaAlSiN3: Eu2+ phosphor-in-glass film-Y3Al5O12: Ce3+ film@Al2O3 plate with aluminum “heat sink”) via management methodology combining “phosphor wheel” and sink” the lighting source This new design makes it effective to transport generated phonons away reduce ionization process, yield stable high-quality white light brightness 4510 lm @ 43 W, luminous efficacy 105 lm/W, correlated temperature 3541 K, rendering index 80.0. Furthermore, film-converted system was also successfully designed, showing more vivid than traditional LED-based projector. work emphasizes importance upon high power irradiation, hopefully facilitates development LD-driven
