Remote phosphor technology for white LED applications: Advances and prospects

Remote phosphor technology for white LEDs provides new encapsulation construction, which separates the blue chip and color converting materials at a large distance. This technology could potentially reduce the working temperature of phosphors and solve the thermal quenching problems and enable us to fabricate flat panel lighting source with enhanced lighting quality. Therefore, remote phosphor technology has drawn a great of attentions from both of the scientific and industrial communities. White LED applications with remote phosphor technology will be further developed into be more functional, high-performance and intelligent. In this review, we summarize the recent advances in remote phosphor technology for white LED with emphasis on the encapsulation structures, devices evaluation as well as the novel down conversion materials. The prospects of remote phosphor technology are also presented.
