LED illumination is because having the advantages such as energy-saving and environmental protection, life-span length, and the reinforcement of people's energy-conserving and environment-protective consciousness in addition, is used by increasing people gradually, and in room lighting field, LED fluorescent tube has been applied to various occasions gradually widely.The structure of existing LED fluorescent tube is generally that PC cover adds aluminium radiator, on the aluminium radiator of a strip, fix an aluminium base, then on aluminium base, fix several LED lamp pearls, then PC cover is fixed on aluminium radiator, then aluminium base is connected with power supply, this class LED fluorescent tube manufacturing cost is high and lighting angle is little, assembling trouble.

Summary of the invention

It is a kind of simple in structure that the utility model provides, and cost is lower and assembling is simple, the fluorescent tube that lighting angle is larger.

For reaching this object, the utility model by the following technical solutions:

A kind of fluorescent tube, comprise pipe and the lamp holder matching with described pipe two ends, on the inwall of described pipe, be symmetrically arranged with the flange that axially runs through pipe, the bottom surface of described flange is connected with lamp plate assembly, the width of described lamp plate assembly is less than close-fitting in the cavity between 20mm and bottom and the inwall of described pipe radiator, and the flange place at the two ends of described pipe is connected with respectively power supply.

Wherein, the vaporific heat-conduction plastic pipe that described pipe is injection moulding integrated molding.

Wherein, described heat-conduction plastic pipe two ends are symmetrically arranged with respectively the external screw thread matching with described lamp holder.

Wherein, the outer circumference surface of described lamp holder is metal shell.

Wherein, described lamp plate assembly comprises aluminium base and the uniform welding LED lamp pearl on described aluminium base, and the width of described aluminium base is less than 20mm.

Wherein, the length of described aluminium base is less than the length of described heat-conduction plastic pipe.

Wherein, described radiator is the length that aluminium extruded type section bar and length equal described aluminium base.

Wherein, in the cavity of described aluminium extruded type section bar, be provided with rib.

Wherein, align with described aluminium base one end in one end of described power supply, and the other end aligns with one end of described heat-conduction plastic pipe.

The beneficial effects of the utility model: the utility model comprises pipe and the lamp holder matching with described pipe two ends, on the inwall of described pipe, be symmetrically arranged with the flange that axially runs through pipe, the bottom surface of described flange is connected with lamp plate assembly, the width of described lamp plate assembly is less than close-fitting in the cavity between 20mm and bottom and the inwall of described pipe radiator, and the flange place at the two ends of described pipe is connected with respectively power supply.Lamp plate assembly directly snaps fit onto in pipe, lighting angle is become in large and light emitting region and there is no dark space, the radiator matching with lamp plate assembly bottom, heat can be shed in time, power supply and pipe clamping and lamp holder and pipe threaded engagement, make assembling simple, and the utility model is simple in structure, cost is lower and assembling is simple, and lighting angle is larger.
