Abstract
We propose electrospun-nanofiber diffusing films to enhance the angular color uniformity (ACU) of remote-phosphor-converted light-emitting diodes (RPC-LEDs). Poly(vinylidene fluoride) electrospun nanofibers/acrylic composite films with different nanofiber thicknesses are investigated. An optimal composite film is obtained based on the balance between the ACU enhancement and luminous flux reduction, which can be applied to RPC-LEDs with different correlated color temperatures (CCTs) to enhance the ACU with a small luminous-flux loss, particularly at higher CCTs. Therefore, the composite films can effectively enhance the ACU of RPC-LEDs while maintaining a high luminous flux.
