Abstract
The utility model discloses an improved type electronic ballast. The improvement is that the winding of an output electrical inductance is composed of the parallel winding of three lead wires. A lengthen magnetic core is arranged in the center of the inductance. The best wire diameter of the wires is 0.21 mm. The length of the magnetic core is 25-40 mm. The improved type electronic ballast increases the induction quantity, decreases the thickness of the winding, decreases vortex flow and corresponding heating value, improves heat dissipation conditions with the temperature rise higher 10 DEG C than environmental temperature when used in 40W lamp, and has the advantages of simple structure, low cost and easy application.
Description
The utility model belongs to the improvement to existing electric ballast, specifically a kind of modified model electric ballast.
Existing electric ballast is when being used for the bigger fluorescent lamp of power (for example 40W), its outputting inductance is often overheated because of the bigger appearance of electric current, and temperature can be elevated to 100 ℃, causes inductance framework to feel like jelly, be out of shape, when serious even burn, influence applying of operate as normal and electronic fluorescent lamp.
The purpose of this utility model is to design a kind of modified model electric ballast, to overcome above-mentioned shortcoming.
The utility model comprises rectifier, high-frequency generator and outputting inductance, it is characterized in that the winding of outputting inductance is formed by three lead coilings arranged side by side, and the lengthening magnetic core is equipped with at the inductance center.
Design of the present utility model has increased the inductance value of inductance, under the situation of same inductance value, reduced the thickness of winding, improved heat dissipating state, eddy current and corresponding caloric value have been reduced, under the identical situation of power, its temperature is only high about 10 ℃ than room temperature (25 ℃), and simple in structure, cost is low, and is easy to implement.
The utility model has following accompanying drawing:
The outputting inductance schematic diagram that Fig. 1 has improved
Fig. 2 modified model electric ballast operation principle schematic diagram
Below in conjunction with accompanying drawing the utility model is elaborated.
The induction structure schematic diagram of Fig. 1 for having improved in the utility model comprises magnetic core M, skeleton and winding, and magnetic core M adopts the lengthening magnetic core, is greater than the length of skeleton usually, for example be chosen as 25～40mm.Because the full-length of magnetic core is 20mm,, also can be processed into other suitable length specially so the column magnetic core butt joint that can to adopt two length be 20mm forms.The also more common skeleton of skeleton will be grown, and for example can be designed to the long skeleton of 20～30mm, and its endoporus can be 5～20mm.The magnetic core owing to extended increases inductance value, thereby has reduced the thickness of winding when inductance is identical, has improved radiating condition.
Another feature of the present utility model is that winding is not common single line structure, but is formed by three lead S coilings arranged side by side, can be between 0.1～0.3mm through the footpath, and to the 40W fluorescent lamp, the best line of lead S directly is 0.21mm.Three-way and around effect fairly obvious, when not adding magnetic core, adopt the solid wire of diameter 0.41, to the 40W fluorescent tube, the temperature rise of inductance L can reach 90 ℃ (30 ℃ of ambient temperatures); Do not add magnetic core equally, three in the lead of employing diameter 0.21, the temperature rise of inductance L is only high 10 ℃ than ambient temperature (30 ℃).
Three-way and around, adopt the lengthening magnetic core simultaneously, winding thickness is reduced, increased inductance value, reduced temperature rise, improved radiating condition, saved the consumption of copper conductor simultaneously, reduced cost, improved the reliability of electric ballast work.
The utility model all can use the connection that hot filament and no hot filament are arranged, and all can reduce the mistake high temperature rise of inductance L.
