Description
Technical field
The technical field of the utility model lighting, in particular a kind ofly take the fluorescent tube that the LED light emitting diode is light source.
Background technology
Increasingly mature and universal along with LED LED driving power technology, make the properties of product of LED illuminating product better, existing LED fluorescent tube has substituted traditional fluorescent material fluorescent tube gradually, and the LED fluorescent tube driving power source adopts Switching Power Supply mostly, and Integration Design, be about to each core: fuse+wave filter+PFC+rectification+high frequency transformation+rectification output is integrated in a circuit board.At present, for the Layout Problem of fuse, the general way that jointly is arranged in the same circuit board with other components and parts of driving power that adopts, be irrational in fact, often increased the difficulty that the LED fluorescent tube is safeguarded.Reason is: the LED fluorescent tube breaks down in number of times, and driving power breaks down and causes the situation of whole LED fluorescent tube cisco unity malfunction to be in the great majority, and wherein because the excessive situation of blowout that causes of electric current accounts for many parts.Traditional fuse and driving power circuit plate integrate, in the time of inspection, need to take out power supply is whole, and then the investigation trouble point, cumbersome, operation is inconvenience also.Therefore, prior art has yet to be improved and developed.
The utility model content
The purpose of this utility model is to provide a kind of LED fluorescent tube that is easy to Inspection and maintenance, but whether the very first time is understood fuse intact, thereby the scope of greatly having dwindled queueing problem, trouble point has shortened maintenance time, be convenient to realize modularized processing, easy to operate.
The technical solution of the utility model is as follows: a kind of LED fluorescent tube that is easy to Inspection and maintenance, include the lighting tube plug at lampshade, LED lamp pearl and substrate thereof, LED driving power, two ends, it is characterized in that, fuse is separately set in arbitrary lighting tube plug, fuse one end connects external power, and the other end is connected with the LED driving power.Further, described lighting tube plug can be opened, and fuse is fixed on separately in the cavity volume of lighting tube plug, and fuse one end connects contact chip, and contact chip connects external power, and the fuse other end is connected with the LED driving power by wire.Particularly, on described lighting tube plug, have groove, fuse directly is nested and is fixed on the fuse carrier member, the fuse carrier member assembly in the groove of lighting tube plug.After the fuse carrier member that will fill fuse is inserted the groove of lighting tube plug, the two ends of a fuse contact jaw that is insured is clamped, and then connecting ejector pin and contact chip, forms electric pathway.Described LED driving power is equipped with the sleeve pipe encapsulation.
Fuse adopts the mode of plug and play, by the fuse carrier member, is separately set in arbitrary lighting tube plug, inserts in the groove of lighting tube plug, after insertion, the fuse two ends are connected with the contact chip in lighting tube plug, during taking-up, only the fuse carrier member need to be pried open, just fuse can be taken out.
The beneficial effects of the utility model: the utility model is arranged in separately lighting tube plug inside to fuse, only need to pry open the fuse carrier member on lighting tube plug, take out the fuse carrier member, the very first time just can understand that whether fuse is intact, thereby greatly dwindled the scope of queueing problem point, even can, by changing intact fuse, check and whether can fix a breakdown, make the LED fluorescent lamp from new normal operation.Greatly shortened the waste of maintenance time and energy.The cloth holding fuse, in the lamp holder position, increases cost limited separately, can not affect the performance of LED driving power, is convenient to realize modularized processing, easy to operate.

The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
Fig. 1 is the part partition schematic diagram that the utility model fuse is arranged in separately lamp holder LED fluorescent tube.Include: lampshade 1, LED lamp pearl and substrate 2 thereof, LED driving power 3, sleeve pipe 4, lighting tube plug 5, fuse 6, contact chip 7, radiation shell 8, fuse carrier member 9, fuse contact jaw 10, thimble 11.Wherein, lampshade 1, LED lamp pearl and substrate 2 thereof, LED driving power 3, sleeve pipe 4, lighting tube plug 5, radiation shell 8 etc. all with routine techniques roughly the same, LED driving power 3 cores of circuit aspect generally are divided into: insurance+wave filter+PFC+rectification+high frequency transformation+rectification output, also belong to routine techniques, LED driving power 3 is equipped with 4 encapsulation of special sleeve pipe.Main improvement is, have groove on lighting tube plug 5, fuse 6 directly is nested and is fixed on fuse carrier member 9,9 assemblies of fuse carrier member are in the groove of lighting tube plug 5, as need check fuse 6 behaviours in service, only need pry open the fuse carrier member 9 on lighting tube plug 5, can know that whether the state that judges fuse 6 is intact.Wherein fuse contact jaw 10 1 ends are connected with thimble 11, and the other end is connected with contact chip 7, and contact chip 7 connects LED driving power 3.Like this, when the fuse carrier member 9 that will fill fuse 6 is inserted the groove of lighting tube plugs 5, the two ends of fuse 6 contact jaw 10 that can be insured is clamped, and then connecting ejector pin 11 and contact chip 7, forms electric pathway.
Fig. 2 is the fuse part schematic diagram that the utility model fuse is arranged in separately lamp holder LED fluorescent tube.Fuse 6 one ends connect external power source by contact chip 7; the other end is connected with LED driving power 3 by wire; like this when value that the electric current over insurance silk 6 that flows through LED driving power 3 circuit is set; fuse 6 will fuse; thereby cut off the electricity supply; avoid large electric current to continue other components and parts are caused to damage, effectively protected the LED driving power 3 of back.Like this, for because fuse 6 blows the fault produced, can directly pry open the fuse carrier member 9 of lighting tube plug 5, take out its interior fuse 6 that is nested, just can be checked through easily the behaviour in service of fuse, and all whole LED driving power 3 will be pulled out to inspection without each resembling in the past.
Fig. 3 is that the utility model fuse is arranged in separately lamp holder LED fluorescent tube driving power source circuit diagram.This circuit diagram is a kind of circuit diagram representative in LED switch drive power supply, from circuit diagram, we can see the operation principle of whole LED driving power, owing to being routine techniques, therefore do not elaborate, but the crucial position that is the fuse place: the F1 that the left superscript of Fig. 3 shows is the position at first entered in external power.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or convert, all these improvement and conversion all should belong to the protection domain of the utility model claims.
