Improved lamp tube module structure

An improved lamp tube module structure is characterized in that a lamp tube is equipped with at least one DC light-emitting element and a power supply conversion device, the power supply conversion device comprises a first fluorescent lamp simulation module and a second fluorescent lamp simulation module, and the first and second fluorescent lamp simulation modules both possess two power supply input connection ends and are electrically connected with a bridge rectifier. The bridge rectifier is electrically connected with the DC light-emitting element, one of the power supply input connection end of the first or second fluorescent lamp simulation module is equipped with a capacitor electrically, thereby reducing and isolating the interactive influence of the DC components between a stabilizer or other input power supplies and a lamp tube module.
