Abstract
The invention provides an LED fluorescent lamp. The LED fluorescent lamp comprises a lamp tube, lamp caps at the two ends of the lamp tube, electrode needles on the lamp caps, and a circuit board inside the lamp tube. The circuit board is provided with elastic metal sheets connected with the electrode needles, the inner ends of the electrode needles are inserted in the elastic metal sheets in a penetrating mode, and the elastic metal sheets are attached to the circuit board. The LED fluorescent lamp is simple and convenient to assemble, and saves the labor cost. The electrical safety is high, and the phenomenon that the potential safety hazards are caused when a conventional electrode needle is connected with the circuit board through a wire, the lamp caps press the wire, and then the wire is broken, or the wire is damaged manually and makes contact with a metal case can be avoided.
Description
Technical field
The invention belongs to lighting technical field, relate to a kind of LED light-emitting device, more specifically say the syndeton relating in particular in LED fluorescent tube.
Background technology
At present in LED industry, method of attachment for LED fluorescent tube input AC operating voltage, generally adopt insulation electric rubber cover wire to connect input, its method of attachment is by two wires that color is different, is welded on respectively on the power supply terminal (L, N) of tube lamp holder and PCB circuit board.
This type of production technology operation of prior art is more, and during manufacturing cost, production capacity is low.And lamp holder inside is a vision dead zone in assembling process, insulation rubber wire is easy to the place of combination between lamp holder and aluminium groove the insulating cement pick up of wire is broken, and causes wire to be connected with metal shell.To user and product producer, all can bring the possibility of electric shock like this, have certain potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention is: the deficiency existing for the LED fluorescent lamp of above-mentioned prior art, a kind of LED fluorescent lamp is provided, and the inner of electricity level pin is closely connected with the metal clips on circuit board.
The technical scheme that the present invention is directed to the problems referred to above and propose is: a kind of LED fluorescent lamp, comprises fluorescent tube, the lamp holder of lamp tube ends, the electrode needle on lamp holder, and the circuit board in fluorescent tube; It is characterized in that: on described circuit board, be provided with the metal clips being connected with electrode needle.
Wherein, intert in metal clips the inner of described electrode needle.Described metal clips adopts surface installation technique to be mounted on circuit board.
Further, described circuit board is inserted on the aluminium groove in fluorescent tube.Described electrode needle is fixed on lamp holder through Shooting Technique.Described lamp holder is arranged on the two ends of fluorescent tube by screw.
Compare with the LED fluorescent lamp of prior art, adopt the advantage of technical solution of the present invention as follows.
1. the assembling of this LED fluorescent lamp is simple and convenient, saves labour turnover.
2. electrical security is high, avoids conventional electrode needle to use in the connection procedure of wire and circuit board, and lamp holder is pushed down wire, makes wire breakage or wire artificial damage contact brought potential safety hazard with metal shell.

Figure comprises: LED, fluorescent tube 1, lamp holder 2, electrode needle 3, circuit board 4, metal clips 5, aluminium groove 6.
The specific embodiment
In order to further illustrate principle of the present invention and structure, existing by reference to the accompanying drawings to a preferred embodiment of the present invention will be described in detail.
A kind of LED fluorescent lamp of the present invention, for the input connection structure of inputting the working volts alternating current of LED fluorescent lamp, adopts metal insert form, is different from traditional insulation rubber wire and connects power supply mode.
On the lamp holder 2 of new a kind of LED fluorescent lamp of the present invention, newly designed the electrode needle 3 of conduction, lengthened the length of electrode needle 3 the inners in lamp holder 2, electrode needle 3 is fixed on lamp holder 2 through Shooting Technique.The inner of two electricity level pins 3 is closely connected with the metal clips 5 of binding post (L, N) conduction on PCB circuit board 4 in fluorescent tube 1 respectively, plays electric action.
The invention of this structure, makes the assembling production process of LED fluorescent lamp simple, has improved on the one hand production production capacity, has saved labor hour; Solved on the other hand in the assembling process of LED fluorescent lamp, conductive connecting is damaged, the life security hidden trouble bringing.
A kind of LED fluorescent lamp of the present invention, comprises fluorescent tube 1, the lamp holder 2 at fluorescent tube 1 two ends, the electrode needle 3 on lamp holder 2, and the circuit board in fluorescent tube 14; On circuit board 4, be provided with the metal clips 5 being connected with electrode needle 3.
Several improvements of a kind of LED fluorescent lamp of the present invention are: the metal clips 5 of the conduction arranging on PCB circuit board 4, adopts electronic circuit surface installation technique SMT technique to be close on PCB circuit board 4; The inner that electrode needle 3 is positioned at lamp holder 2 lengthens; After LED fluorescent lamp has been assembled, intert in metal clips 5 inside the inner of electrode needle 3, elasticity clamping.
As shown in Figure 1, by metal clips 5 pasters (by Reflow Soldering), on the PCB of LED fluorescent lamp circuit board 4, PCB circuit board 4 plug-in mountings are fixed on above the aluminium groove 6 in fluorescent tube 1.
As shown in Figure 2, lamp holder 2 is screwed in to the two ends of fluorescent tube 1, metal clips 5 is aimed in the inner of the lengthening of the electrode needle 3 on lamp holder 2, and the inner of electrode needle 3 is interted 5 li of metal clips.
As shown in Figure 3, the electrode needle 3 of lamp holder 2 just communicates with the circuit of PCB circuit board 4 like this, plays electric action.
The effect that this invention embodies after implementing: the assembling of LED fluorescent lamp is simple and convenient, saves labour turnover.Electrical security is high, avoids the electrode needle 3 on conventional lamp holder 2, and with wire, with in PCB circuit board 4 connection procedures in fluorescent tube 1, lamp holder 1 is pushed down wire, makes wire breakage or wire artificial damage contact brought potential safety hazard with metal shell.
This structure is applicable to the LED fluorescent lamp of single-ended and both end power supplying form.
Foregoing; it is only preferred embodiment of the present invention; not for limiting embodiment of the present invention; those of ordinary skills are according to main design of the present invention and spirit; can carry out very easily corresponding flexible or modification, therefore protection scope of the present invention should be as the criterion with the desired protection domain of claims.
