Further, described LED illuminating module is that multiple LED chips are arranged and formed, and by welding or the general mode such as engaging is fixed, and then realize the parallel connection of multiple LED chips.

Further, described drive block is placed in a lamp holder, and the lamp holder of holding drive block is for not entering socket, and another lamp holder is for entering socket; This does not enter on socket inwall to be provided with insulating barrier.

Further, described drive block comprises block and base plate, and block is fixed on base plate and base plate bottom surface has block-shaped protrusion, and the edge of this block, base plate and block-shaped protrusion is with not enter socket inwall suitable, form snap-in structure, thereby realize the fixed structure of drive block.

Further, described insulating barrier is SOI glue-line, and this SOI glue-line and described not enter socket inwall suitable.

The utility model is improved to connected structure by existing lamp holder with being threaded of fluorescent tube, and concrete beneficial effect and advantage are as follows:

1, utilize the guide wall that lamp holder inwall extends to form to peg graft and coordinate with lampshade, and then realize the connected structure of lamp holder and lampshade, realize the convenient object of installing and dismantling;

2, guide wall bends inwards and forms two depressions, and each depression engages with the projection that lampshade inserted terminal coordinates, form the interface arrangment of lamp holder and lampshade, extended guide wall plays positioning function for lampshade simultaneously, effectively prevent the play of lampshade, thereby improve exposure intensity;

3, utilize a hole of leading to the end effectively to reduce the inconvenience in mould is manufactured, obtain face shaping attractive in appearance and form simultaneously.
