Abstract
The utility model relates to a mini-sized common mode filter for an LED lamp. The mini-sized common mode filter comprises a magnetic core, an enameled wire and pins. The magnetic core is made of materials of high permeability. The mini-sized common mode filter has the advantages of being small in size.
Description
Technical field
The utility model relates to the small-sized common-mode filter of a kind of LED lamp.
Background technology
Common-mode filter possesses low differential mode noise signal and suppresses interference source, is difficult to distortion in high speed signal.It is good that noise suppresses countermeasure, and high common mode noise suppresses and hang down the characteristics of differential mode noise signal inhibition.
At present, common-mode filter is made up of magnetic core, enamelled wire and stitch, and magnetic core adopts FERRITE CORE.Because the factor of magnetic core, in order to obtain bigger inductance value, need to increase the volume of magnetic core, so, just make the volume of whole common-mode filter increase, load at some small sizes (as the LED lamp) is difficult to assemble, and therefore, the volume that need reduce common-mode filter reaches user demand.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model provides the small-sized common-mode filter of a kind of LED lamp, the utlity model has the little characteristics of volume.
The realization the technical solution of the utility model is as follows:
The small-sized common-mode filter of LED lamp comprises magnetic core, enamelled wire and stitch, and described magnetic core is the magnetic core that high-permeability material is made.
Adopted such scheme, magnetic core is the magnetic core that high-permeability material is made, because the magnetic permeability of magnetic core improves, therefore the volume that can dwindle can reach required big inductance quantity requirement, after the volume-diminished of magnetic core, the volume of whole common-mode filter also dwindles thereupon, so, just can assemble the common-mode filter of small size in the LED lamp.
Further, describedly make the magnetic core that magnetic core is permalloy.The magnetic core that adopts this material to make, its volume can be contracted to long 10mm, and wide 10mm in the high 10mm, possesses very big inductance value for a short time in reduced volume, to reach the required filter action of LED lamp.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Embodiment
With reference to Fig. 1, the small-sized common-mode filter of LED lamp of the present utility model comprises magnetic core 1, enamelled wire 2 and stitch 3, and enamelled wire 2 is wound on the magnetic core 1, and described magnetic core is the magnetic core that high-permeability material is made.The described high-permeability material of making magnetic core is permalloy.The length of magnetic core is 10mm, and wide is 10mm, and height is 10mm.
