LED LAMP STRING DEVICE IN WHICH THE LED LAMP ASSEMBLIES HAVE ROUGHLY THE SAME SHINING LUMINANCE, AND ITS REALIZING METHOD

摘要

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. The current invention overcomes shortcoming of ragged luminance of LED luminous body in LED lamp assemblies, and enhances beauty of said LED lamp string assemblies; enriching colors of light emitted by said LED lamp string device; if LED lamp string device use LED luminous bodies having the same electrical specifications, the abnormal damage problem of the above LED luminous bodies also can be avoided effectively.
