Abstract
The invention provides an inductance power integrated type light-emitting diode (LED) power source which mainly solves the problems that an existing inductor is large in calorific value and big in size; an existing power tube is bad in heat dispersion and big in base pin stress; and heat conductivity performance and strength are bad in the prior art. The inductance power integrated type LED power source comprises a circuit board, a power box body and a power box cover, wherein an inductor is arranged on the side wall of the power box body, the inductor is electrically connected with the circuit board, a power tube is electrically connected with the circuit board, one side, far away from the circuit board, of a base plate of the power box body is completely attached to a installed part, and the base plate of the power box body and the side wall of the power box body form an integrated insulation heat conduction box. According to the inductance power integrated type LED power source, fine lines are adopted, the diameter of each fine line is smaller than 0.1mm, accordingly effective area is enlarged, and the size of the inductor is decreased. Moreover, the power tube is arranged on the side wall of the power box body, and thus not only is the problem of heat dissipation solved, but also the problem of base pin stress is solved. The power box body is of an integrated part, heat dissipation is uniform, and strength is high.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to the one-piece type LED power supply of a kind of electric inductance power.
Background technology
The inductance of existing LED power supply generally takes thick line to be wound around (wire diameter is generally greater than 1mm), can cause like this Kelvin effect of inductance to increase, and the inductance heating is large; In order to address this problem, the technical staff adopts the mode of dwindling wire diameter, but after dwindling wire diameter, fine rule is more difficult fixing after winding, even can line pressure is disconnected.
The power tube of existing LED power supply generally is set directly on wiring board, causes like this heat comparatively concentrated, is unfavorable for heat radiation; In order to address this problem, the technical staff adopts the set-up mode perpendicular to wiring board, but has increased like this stress of pin, and long-term use easily causes potential safety hazard.
The existing power supply box body is generally the split part, cause like this intensity of power supply box body lower, and the each several part heat dispersion is inconsistent, is unfavorable for heat radiation; Simultaneously, does not generally process existing power supply box body bottom, causes power supply bottom and mounted piece to be fitted not tight, is unfavorable for the heat conduction.
Summary of the invention
The invention provides the one-piece type LED power supply of a kind of electric inductance power, mainly solved existing inductance caloric value large, volume is large; Existing power tube heat dispersion is poor, pin stress is large; The problem that prior art heat-conductive characteristic and intensity are relatively poor.
Concrete technical solution of the present invention is as follows:
The one-piece type LED power supply of a kind of electric inductance power, comprise wiring board, power supply box body and power supply lid, above-mentioned wiring board is fixedly installed in the power supply box body, above-mentioned power supply box body is " U " type or " L " type, comprise power pack body sidewall and power supply box plate, wiring board is fixedly installed on the power supply box plate; Be provided with inductance on above-mentioned power pack body sidewall, inductance is electrically connected to wiring board; Above-mentioned inductance is by the fine rule coiling of diameter less than 0.01mm; Above-mentioned inductance is fixed on the power pack body sidewall by screw, be provided with the insulating radiation elastomeric pad between above-mentioned inductance one side and power pack body sidewall, above-mentioned inductance opposite side is disposed with the insulating radiation elastomeric pad, fixedly compressing tablet and hold-down nut, fixedly compressing tablet is provided with the flange that is used to the screw guiding near the insulating radiation elastomeric pad; Above-mentioned power tube is electrically connected to wiring board, and power tube is fixedly installed on the power pack body sidewall; Above-mentioned power supply box plate away from circuit board one side be mounted the position and fit fully, the insulating heat-conductive box that power supply box plate and power pack body sidewall are formed in one.
The invention has the advantages that:
1, the present invention has adopted the fine rule of diameter less than 0.1mm, adopt simultaneously the insulating heat-conductive cushion to be carried in coil two ends, then used the fixedly compressing tablet that turns over time with ring-type that it is fixed, increased effective area, dwindled the volume of inductance, volume can be down to original 1/5.
2, the present invention adopts power tube is arranged on the power pack body sidewall, and then pin is connected with wiring board, because the power pack body sidewall is that heat sink material is made, and power tube is completely fixed and be fitted on the power pack body sidewall, namely solve heat dissipation problem, solved again the stress problem of pin.
3, power supply box body provided by the invention is integrated part, and heat radiation is even, and intensity is high; Simultaneously, the box body back is processed, make its with mounted piece between contact closely, be beneficial to the heat conduction.
