Abstract：Remote phosphor LED is a promising technical solution for the heat dissipation in LED devices . In this paper , the phosphor conversion layer is prepared by UV curing of resin mixture composed of red and yellow phosphor .A simple white LED demo device is fabricated with this phosphor conversion layer to study the influences of composition of the phosphor layer , the distance between the chip and phosphor layer and the input electric current on the performance of the white LED device .It is found that the composition of phosphor layer does affect the color rendering index and color temperature , but the distance between the chip and the phosphor conversion layer and input electric current have little influence on optical property . In this paper , the blinding light from the LED chip is also eliminated with light scattering agent .The results of this work could be a reference for structure design of new white LED devices .
