Two magnetic cores, in E shape, be relatively plugged in described supporting bracket, described magnetic core and described bobbin also arrange a safety adhesive tape in its outside after assembling;
At least one coiling group, on the drum stand of winding between the described supporting bracket of described bobbin, described coiling group outside is wound around insulating tape.
Reasonable, LED transformer of the present utility model, is characterized in that,
Described coiling group comprises first, second two groups further, and first, second group coiling described line is separately connected with described PIN pin.
Reasonable, LED transformer of the present utility model, is characterized in that,
The number of turn 180 of described first group of coiling, around to being CCW, be 1UEWF5/ ф 0.125mm with wire gauge lattice, inductance value is 1.410%, Q value >100;
The number of turn of described second group of coiling is 20 circles, around to being CCW, is 1UEWF ф 0.23mm with wire gauge lattice.
Reasonable, LED transformer of the present utility model, is characterized in that,
The model of described magnetic core is EF20, and permeability can reach 40nH/N
2.
Reasonable, LED transformer of the present utility model, is characterized in that,
