Abstract
A split electronic ballast is characterized in that inductive coils, a pulse transformer, a capacitor and related electronic components which have low calorific power are arranged in an internal circuit board to form an internal circuit; a multi-column plug is communicated with the internal circuit; a triode, a rectifying diode, a rectifying circuit and related partial electronic components which all have high calorific power and are easily damaged are arranged on an external circuit board to form an external circuit; a multihole socket is connected with the external circuit; and the multi-column plug matches with the multihole socket. When the split electronic ballast with the structure is used, the internal circuit is arranged on lamps and fixedly connected with the lamps, and the external circuit is additionally provided with radiating hoes before encapsulated and connected with the internal circuit through the multi-column plug; and when some electronic components of the triode and the rectifying diode which are arranged in the external circuit are damaged, only the external circuit needs to be changed. The utility model overcomes the defect that once any one of the damaged triode, the rectifying diode or a diode of the prior electronic ballast is damaged, the whole electronic ballast is invalidated due to inconvenient maintenance.
Description
Technical field
The utility model relates to the device that a kind of light fixture is used, especially a kind of electric ballast of light fixture.
Background technology
Present prior art, a kind of electric ballast comprise that pulse transformer, inductance coil, triode, rectifier diode, resistance, diode and electric capacity constitute.Pulse transformer, inductance coil are the heating less elements, and triode, diode, resistance are in the course of the work, and most of caloric values are bigger, and when heat can not get distributing effectively, Yin Gaowen and fragile caused electric ballast integral body to scrap.Existing problems are: useful life is short, and maintenance is inconvenient.
Summary of the invention
The purpose of this utility model is: the electric ballast of a kind of minute body structure is provided, and it is long service life not only, and easy to maintenance.
The utility model is achieved in that the electric ballast of a kind of minute body structure, comprise pulse transformer, inductance coil, triode, rectifier diode, resistance, diode and electric capacity, its special character is: the inductance coil that caloric value is little, pulse transformer, electric capacity and associated electronic components are installed in and constitute built-in circuit on the internal circuit board, and a multicolumn plug and built-in circuit are connected;
Big, the flimsy triode of caloric value, rectifier diode, rectification circuit and relevant portions of electronics element are installed in and constitute outer circuits on the external circuit board, and a porous socket is connected with outer circuits; The multicolumn plug cooperates with porous socket.
The utility model is the electric ballast of a kind of minute body structure, owing to adopt such structure, in use, built-in circuit is installed on the light fixture and is fixedly connected with light fixture, but outer circuits adds louvre when encapsulation, be connected with built-in circuit by the multicolumn plug; When indivedual electronic components of the triode in the outer circuits, rectifier diode damage, only need to change outer circuits and get final product.Overcome in the prior art, when damaging, caused because of keeping in repair inconvenience because of one of triode, rectifier diode and diode, and whole defective of scrapping.
Description of drawings
Fig. 1 is the schematic diagram of this usefulness utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1.The electric ballast of a kind of minute body structure, comprise pulse transformer T, inductance coil L, triode, rectifier diode ST, resistance, diode and electric capacity, inductance coil L, pulse transformer T, electric capacity that caloric value is little, and other electronic component diode is installed on the internal circuit board 1 and constitutes built-in circuit, and a multicolumn plug 4 is connected with built-in circuit;
Big, the flimsy triode of caloric value, diode, rectifier diode ST, rectification circuit, resistance reach partition capacitance and are installed in the outer circuits of formation on the external circuit board 2, and a porous socket 3 is connected with outer circuits; Multicolumn plug 4 cooperates with porous socket 3.
