Background technology

Fluorescent lamp is as light source, and is more energy-conservation than conventional incandescent, therefore is widely used in industry and domestic lighting, and accessories such as the lamp socket supporting with it, lamp bracket and lamp box have formed standard.Along with the development of new-type light source led, it is inevitable that its application at lighting field has become.LED lamp type and traditional fluorescent lamp greatly differ from each other at present, therefore it need be designed to the fluorescent lamp shape, but present LED fluorescent lamp, generally manufacture an integral body with body, when body damages, also to scrap even the LED light emitting module is intact thereupon, cause the wasting of resources easily.

The utility model content:

For this reason, the purpose of this utility model is to provide a kind of Novel LED fluorescent lamp pipe, can dismantle between the circuit board of this fluorescent tube heat dissipating housing, lampshade and welding LED, has great convenience for the user installation, and can be recycled, and has avoided waste.

For achieving the above object, the utility model is mainly by the following technical solutions:

A kind of Novel LED fluorescent lamp pipe includes heat dissipating housing (1), lampshade (2), lamp holder covers (3) and is welded with LED and the circuit board of power supply (5) (4), circuit board (4) is electrically connected with electrode (301) on being fixed on lamp holder lid (3), heat dissipating housing (1), lampshade (2) is semicircular arc, the two is combined to round tubular, wherein the lower end arranged outside of heat dissipating housing (1) has draw-in groove (101), the inboard is provided with draw-in groove (103) and screw (102), draw-in groove (101) and draw-in groove (103) extend axially along heat dissipating housing (1), both sides, lampshade (2) upper end are provided with hooked hand (201), may be stuck in by this hooked hand (201) in the outer side bayonet slot (101) of heat dissipating housing (1), realize fixedlying connected of lampshade (2) and heat dissipating housing (1).

Described heat dissipating housing (1) is made by aluminium base sheet material.

Described lampshade (2) is made by transparent material.

Compared with prior art, the utility model directly replaces fluorescent tube to use, and need not more

Compared with prior art, the utility model directly replaces fluorescent tube to use, and need not to change miscellaneous part in the fluorescent lamp device, and dismounting and installation are all very convenient; Simultaneously the led circuit plate is fixed in the heat dissipating housing, and and heat dissipating housing between form bigger cavity, thereby the heat that produces when making LED luminous can be exhaled by heat dissipating housing rapidly, thereby reduce the temperature of LED fluorescent tube.

Description of drawings:

Fig. 1 is a structure assembling schematic diagram of the present utility model.

Fig. 2 is along the axial schematic diagram of fluorescent tube among Fig. 1.

Fig. 3 is the utility model circuit board LED distribution schematic diagram.

Identifier declaration among the figure: heat dissipating housing 1, draw-in groove 101, screw 102, draw-in groove 103, lampshade 2, hooked hand 201, lamp holder lid 3, electrode 301, circuit board 4, LED lamp 401, power supply 5.

The specific embodiment:

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

See also shown in Figure 1ly, Fig. 1 is a structure of the present utility model assembling schematic diagram.The utility model provides a kind of Novel LED fluorescent lamp pipe, and this LED fluorescent tube is installed in the existing fluorescent lamp device, and it is mainly used in the replacement traditional fluorescent lamp tube.Wherein the utility model mainly includes heat dissipating housing 1, lampshade 2, Cap casing 3 and is welded with LED and the circuit board of power supply 54, and described circuit board 4 is electrically connected with electrode 301 on being fixed on lamp holder lid 3.

As shown in Figure 2, Fig. 2 is along the axial schematic diagram of fluorescent tube among Fig. 1.Heat dissipating housing 1 of the present utility model, lampshade 2 are semicircular arc, the two is combined to round tubular, what wherein heat dissipating housing 1 adopted is that the manufacturing of heat dispersion good metal aluminium forms, its lower end arranged outside has draw-in groove 101, the inboard is provided with draw-in groove 103 and screw 102, and above-mentioned draw-in groove 101 and draw-in groove 103 extend axially along heat dissipating housing 1; Described lampshade 2 adopts transparent material to make, and it has certain elasticity, and both sides, lampshade 2 upper end are provided with hooked hand 201, may be stuck in by this hooked hand 201 in the outer side bayonet slot 101 of heat dissipating housing 1, realize fixedlying connected of lampshade 2 and heat dissipating housing 1.
