Being removable between described lamp holder and the described fluorescent tube is connected.

Described lamp holder is that lamp holder is connected on the described fluorescent tube by screw with removable connection between the described fluorescent tube.

Described lamp holder is to be provided with internal thread in lamp holder with removable connection between the described fluorescent tube, is being provided with external screw thread on the outer wall on the described fluorescent tube, and both are by being threaded.

Described lamp holder is to be provided with bayonet lock in lamp holder with removable connection between the described fluorescent tube, establishes " L " shape slot in described lamp tube ends, is connected by bayonet lock between described lamp holder and the fluorescent tube.

Described fluorescent tube is made of glass.

As to improvement of the present utility model, described fluorescent tube is made up of two semicircles, and one of them semicircle is made by aluminium alloy, and another semicircle is made by transparent plastic, and both connect by the mode of clamping.

As to further improvement of the utility model, on the outer wall of the described semicircle of making by aluminium alloy, be provided with several heat sink strips.

Described fluorescent tube is made of transparent plastic.

The utility model can also be designed to all-plastic and make, and wherein half is a pellucidity, and second half is an opaque state.

But the utility model will be with being movably arranged in the fluorescent tube of the pcb board plug of LED lamp, and be connected being removable between lamp holder and the described fluorescent tube, and like this, that the utility model just has is simple in structure, I﹠M advantage easily.
