Abstract
The utility model relates to an electronic ballast for fluorescent lamp, which is suitable for ordinary florescent lamps. The utility model is characterized in that the two mutual coils of the coupling coil of the utility model, which utilize a foil copper skin, are printed on a printed circuit board; a magnetic rod iron core which is wound with a reactor coil is inserted into the two mutual coils which are arranged on the printed circuit board; the weld spots of the utility model can be reduced, and the production cost of the utility model can be reduced by 10-15%. The utility model has the advantages of long service life, convenient maintenance, and wire saving.
Description
The utility model relates to a kind of electronic ballast for fluoresent lamp, is applicable to conventional fluorescent lamps.
Before the utility model was made, all electric ballast coupling coils had two kinds: separation type and monolithic devices.The former is made up of a three-winding magnet ring and a reactor, makes many, the complex process of printed substrate solder joint, has increased volume and production cost.The latter is produced on reactor and mutual inductor on the same iron core, makes the coiling complex process, gets end of the same name easily wrong, and maintenance difficult.More than in two kinds of electric ballasts, be difficult to keep the symmetry of two mutual inductor induced voltages, electric ballast is shortened useful life.
The utility model is at the problem of above-mentioned existence and provide a kind of two mutual inductors are printed on electric ballast on the printed substrate, reduces production costs to reach, reduced volume, the purpose in prolongation electric ballast life-span.
The purpose of this utility model realizes by following technical measures: make a call to a hole on the electric ballast printed substrate, the hole can just be put the bar magnet iron core into, around the hole, utilize the Copper Foil leather of printed substrate to make two mutual inductors, the bar magnet iron core is vertically put into the hole, and reactor winding is on the bar magnet iron core.
Following the utility model will provide embodiment in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
With reference to diagram, (a) in the circuit diagram, reactor winding N
1Oscillates loop metering function is responded to mutual inductor N by bar magnet iron core M simultaneously
