Abstract
The utility model relates to an LED (light-emitting diode) lamp tube. The LED lamp tube comprises an LED lamp housing constituted by connecting a semi-circular aluminum tube with a semi-circular PC (polycarbonate) cover, wherein a PCB (printed circuit board) is fixed in a narrow PCB clamping groove arranged outside the aluminum tube, LED chips on the base board are uniformly distributed and arranged in a single row, a constant-current driving power supply is built in the aluminum tube, and lamp caps with buckles for fixing are connected at the two ends of the LED lamp housing. The PCB clamping groove comprises a T-shaped part and a reverse T-shaped part; lamp cap clamping grooves are respectively stamped at the two ends of an arc top part of the aluminum tube; and the input end of the constant-current driving power supply is connected with the lamp caps, and the output end of the constant-current driving power supply is connected with the PCB.
Description
Technical field
The utility model technology relates to a kind of lamp tube structure, especially relates to a kind of shell mechanism LED fluorescent tube.
Background technology
The structure diversification of current LED lamp, make the LED lamp obtain development widely in lighting field, nature can be pursued safety, simple to operate and economical and practical, more people are accepted and use the LED lamp, but, LED fluorescent tube assembling procedure in the market is more loaded down with trivial details, cost of labor is higher, LED fluorescent tube as the patent No. 201120140010.7, lamp holder has fixedly increased assembly process and difficulty with screw, when keeping in repair repeatedly, also there will be the screw stripped thread to cause the loosening phenomenon of lamp holder, and existing LED fluorescent tube draw-in groove position is near the tube wall on aluminum pipe flat transverse both sides, cause the width of adopted pcb board all to be greater than 19mm, problems has brought higher material cost and cost of labor.
The utility model content
In view of the existing problem in front, the utility model provides a kind of LED fluorescent tube, particularly has the LED fluorescent tube that constriction shape PCB draw-in groove designed and carried the snap fit lamp holder.
A kind of LED fluorescent tube, comprise: semicircular aluminum pipe and semicircle PC cover connect and compose the LED lamp housing, pcb board is fixed in the constriction shape pcb board draw-in groove of aluminum pipe, the width of described pcb board is less than 19mm, LED chip on this pcb board is for being uniformly distributed setting, within constant-current driving power supply is built in aluminum pipe, what LED lamp housing two ends connected is to carry the fixing lamp holder of snap fit.Described pcb board draw-in groove is that " fourth " font forms with reverse " fourth " font, and the draw-in groove width is less than 19mm; Lamp holder draw-in groove of each punching press of Fen De two ends, described aluminum pipe arc top; The input of described constant-current driving power supply is connected with lamp holder, and output is connected with pcb board.
As can be seen from the above technical solutions, the utility model technology has the following advantages:
Carry the fixedly assembling simple and fast of lamp holder and LED tube housing of snap fit, reduce cost of labor, the design of constriction shape pcb board draw-in groove can make the LED fluorescent tube can adopt width to be less than the pcb board of 19mm, thereby reduces the consumption of pcb board material, has reached the effect of saving material and cost of labor.

The specific embodiment
Refer to Fig. 1, Fig. 2, Fig. 3, be depicted as the structure chart of the utility model one embodiment, in the present embodiment, the LED fluorescent tube, comprise: semicircle aluminum pipe 3, semicircle PC cover 2, pcb board 4, LED chip 5, constant-current driving power supply 6, lamp holder 1 forms, the fixed edge 201 of semicircle PC cover 2 covers the identical LED lamp housing that connects and composes of draw-in groove 302 with the PC in semicircle aluminum pipe 3, pcb board 4 is arranged on the outer pcb board draw-in groove 303 of aluminum pipe 3, pcb board draw-in groove 303 is that " fourth " font forms with reverse " fourth " font, this shape can steadily fixedly be placed in top pcb board 4, LED chip 5 is welded on pcb board 4, and be uniformly distributed, what LED lamp housing two ends connected is to carry the fixing lamp holder of snap fit 1, snap fit 101 in lamp holder 1 coincide and is connected and fixed with the lamp holder draw-in groove 301 in aluminum pipe 3, the input that constant-current driving power supply 6 is built in constant-current driving power supply 6 within aluminum pipe 3 is connected with lamp holder 1, output is connected with pcb board 4.
The utility model technology provides the LED fluorescent tube, and compared with prior art, manufacturing procedure is simple, assembles easyly, saves the pcb board material, has advantages of the material of saving and cost of labor.
The detailed introduction of above a kind of LED lamp tube structure that the utility model technology is provided, for one of ordinary skill in the art, thought according to the utility model technology, all will change in specific embodiments and applications, in sum, this description should not be construed as the restriction to the utility model technology.
