Background technology
At present, traditional be applied on the lighting devices such as backlight, electronic energy-saving lamp, illuminating lamp the choking-winding structure usually as depicted in figs. 1 and 2, it is to be made of di-iron trioxide ferrocart core and the manual coiling of enameled wire loop.When big current work, the temperature of magnetic core reach 55 ℃ or more than, externally can produce bigger leakage inductance or stray field, the choking-winding of manual coiling simultaneously is big in manpower demand, and, because brightness that the leaking of leakage inductance makes the lifetime of lamp, the EMI of product disturb causes lamp greatly and starting speed and noise can't reach desirable requirement.
The utility model content
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, provide a kind of anti-current strength big, energy-conservation, durable, the life-span is long, anti-electromagnetic interference performance is good, can reduce temperature rise, and can reduce its occupation space and external form fineness, the choking-winding that is used for lighting device with low cost.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme: design a kind of choking-winding that is used for lighting device, comprise shell with uncovered storage tank, be provided with coil and magnetic core in this uncovered storage tank, described magnetic core is the clavate magnetic core, described coil is a spiral coil, and this spiral coil is on the clavate magnetic core; The electrode pin at described spiral coil two ends stretches out outside the shell from the notch of storage tank.
Further, described spiral coil and clavate magnetic core are assembled into one, the outer surface of spiral coil is adhesively fixed by bonding agent shell medial surface corresponding with it, be respectively equipped with insulating trip between the two ends of clavate magnetic core and its corresponding shell medial surface, described insulating trip is adhesively fixed on respectively on two end faces of clavate magnetic core, can adjust the anti-electric current effect and the current strength of choking-winding by the thickness that changes insulating trip.
Preferably, described shell is cube or rectangular-shaped lid shape shell, and the uncovered storage tank of its inside also is a cube or rectangular-shaped.This shell can adopt ferrite or ferrocart core punch forming.
Preferably, described spiral coil adopts enamelled wire institute coiled.
Preferably, described clavate magnetic core is square or the circular rod magnetic core, and its material can be selected ferrite or ferrocart core for use.
Preferably, described choking-winding integral body is parallel or vertical setting.
The beneficial effects of the utility model are embodied in: electric current is through coil when power supply opening, then coil produce electromagnetic induction can well usefulness work, can resist the interference of EMI electromagnetic interference and other electronic building bricks and the operating efficiency of raising choke, also can prevent leaking of the electromagnetic field of choking-winding own, thereby more energy-conservation and durable, and prolonged useful life; Simultaneously, can also bear the process of hard intensity peak current, and problem of temperature rise has also obtained solution (＜30 ℃).In addition, be applied in when can improve electric property on the lighting device, also reduced the volume of choking-winding widely, oversimplify operation technique and improved the circuit object and touched fail safe.
