Abstract
A lamp tube module structure is configured with at least one DC light-emitting element and a power conversion apparatus in a lamp tube, where the power conversion apparatus comprises a first fluorescent lamp simulation module and second fluorescent lamp simulation module, the first fluorescent lamp simulation module and second fluorescent lamp simulation module respectively have two power input connection ends, and respectively in electric connection with a bridge rectifier in electric connection with said DC light-emitting element. One of the power input connection ends of the first fluorescent lamp simulation module and/or second fluorescent lamp simulation module is configured to electrically connect a capacitor adapted to reduce and isolate the interaction influence of an electric ballast or other kinds of input power sources on a DC component of said lamp tube module.
