High efficient light emitting devices with additiona scattering layer and reflecting medium for white lig generation
Multiexcitation of phosphors, additional scattering layer around the chip and special re- flecting medium were proposed to improve the luminous efficiency and color properties of LED devices. LED devices with an n-UV Ga(In)N chip as well as blue GaN chip and multiexcited phosphors were developed...
