Description
Technical field
The utility model relates to electric component technical field, relates in particular to a kind of transformer and is provided with the driving power of this transformer, a kind of driving power that can effectively reduce the transformer of electromagnetic interference and be provided with this transformer specifically.
Background technology
Along with the development of LED lamp lighting technology, LED is applied in a lot of occasions such as household electrical appliance, general lighting, street lamp.The driving power of existing LED lamp, the same with the power supply of other applications, generally comprised transformer and circuit board, transformer has played very important effect.
Transformer is as at driving power; the particularly main electronic original part in the circuit of LED driving power; transformer often can produce certain electromagnetic interference when work; it is electromagnetic wave; electromagnetic wave can affect the normal work of whole driving power and other parts components and parts, is unfavorable for the work of driving power.
Because electromagnetic wave can affect the work of whole driving power, therefore need to remove this electromagnetic wave as far as possible, present common way is, also needs to increase other element and controls, and so just increased the production cost of driving power.Therefore electromagnetic interference, how to remove transformer on the basis that does not increase production cost becomes those skilled in the art makes great efforts the direction of research.
Therefore,, for above deficiency, the utility model provides a kind of driving power that can effectively reduce the transformer of electromagnetic interference and be provided with this transformer.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to solve transformer in existing driving power when work, often can produce certain electromagnetic interference; affect the normal work of whole driving power and other parts components and parts; removing electromagnetic interference need increase other element and control, and has improved the problem of production cost.
(2) technical scheme
In order to solve the problems of the technologies described above, the utility model provides a kind of transformer, and this transformer comprises iron core, in the center pillar outer felt of described iron core, is wound with winding, is provided with the isolation strip for electromagnetic wave absorption in described winding.
Further, described isolation strip is Copper Foil.
Further, described winding comprises armature winding and secondary winding, and described Copper Foil is arranged between described armature winding and secondary winding.
Further, in described winding, be also provided with insulating tape.
Further, the adjacent setting of described Copper Foil and insulating tape.
The utility model also provides a kind of driving power, and this driving power comprises above-mentioned transformer.
(3) beneficial effect
Technique scheme tool of the present utility model has the following advantages: transformer of the present utility model by being provided with isolation strip in winding, isolation strip adopts Copper Foil, because copper strips can absorb the electromagnetic wave of interference, earth terminal by wiring board discharges, thereby reduced the electromagnetic wave producing, the impact that makes circuit avoid electromagnetic wave to bring, also reduced product radiation, without increasing more electronic component, the production cost of transformer is reduced greatly, can be applied to widely in all types of drive circuits, can effectively guarantee the stability of product operation simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment transformer.
In figure: 1: iron core; 2: winding; 3: isolation strip.
Embodiment
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope that the utility model is protected.
As shown in Figure 1, a kind of transformer that the utility model embodiment provides, this transformer comprises iron core 1, in the center pillar outer felt of described iron core 1, is wound with winding 2, is provided with the isolation strip 3 for electromagnetic wave absorption in described winding 2.Due to the characteristic of copper, copper has the effect of shielding and electromagnetic wave absorption, and therefore, preferably, described isolation strip 3 is Copper Foil.
Because copper strips can absorb the electromagnetic wave of interference, earth terminal by wiring board discharges, thereby reduced the electromagnetic wave producing, the impact that makes circuit avoid electromagnetic wave to bring, has also reduced product radiation, without increasing more electronic component, the production cost of transformer is reduced greatly, can be applied in various drive circuits, be mainly used in driving power, electricity-saving lamp, especially in LED driving power.
In order to reach better effect, in described winding 2, be also provided with insulating tape, conventionally, the adjacent setting of described Copper Foil and insulating tape, when producing winding 2, Copper Foil and insulating tape are wound between the coil of winding together, can play the effect that reduces electromagnetic interference, also can play the effect of insulation simultaneously.
Common, described winding 2 comprises multiple armature windings and multiple secondary winding, and described Copper Foil is arranged between described armature winding and secondary winding.Certainly, also can be located at as required in armature winding and/or secondary winding.
The utility model also provides a kind of driving power, and this driving power comprises above-mentioned transformer.
In sum, transformer of the present utility model by being provided with isolation strip in winding, isolation strip adopts Copper Foil, because copper strips can absorb the electromagnetic wave of interference, earth terminal by wiring board discharges, thereby reduced the electromagnetic wave producing, the impact that makes circuit avoid electromagnetic wave to bring, also reduced product radiation, without increasing more electronic component, the production cost of transformer is reduced greatly, can be applied to widely in all types of drive circuits, can effectively guarantee the stability of product operation simultaneously.
Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of the each embodiment technical scheme of the utility model.
