Abstract: A LED lamp string device in which the LED lamp assemblies have roughly the same shining luminance, and its realizing method, based on the said LED lamp string device comprising a plurality of LED lamp assemblies and a power supply module, make decorative covers using different material that have different transparency based on the different luminance classes, let the rate of transparency of said decorative cover correspond with the above-mentioned light-emitting luminance class of said LED luminous bodies based on the inverse relation; Put said decorative covers onto suitable LED luminous bodies respectively based on the said inverse relation so as to make LED lamp assemblies covered with suitable translucent decorative hoods have roughly the same shining luminance.

Abstract: An ornamental LED lamp string assembly comprising lamp subassemblies, ornamental hoods, a power supply unit and conducting wires, said lamp subassembly comprises a shell, a socket sleeve and a light-emitter, the light-emitter is inserted into the socket sleeve and they are inserted, in turn, into the shell; said wires connect output terminals of the power supply unit to all the lamp subassemblies; particularly, said light-emitter are all LED devices of the same specification emitting white or light-yellow light; said hoods comprises monochromatic items at least of two kinds in similar sizes, however, the two kinds of hoods are in different colors. Owing to the fact that said light-emitters are all LED devices of the same specification, their brightness is the same, and power supply efficiency is enhanced, its service life is lengthened.
