Abstract
The invention provides an inductor heat-radiating type light-emitting diode (LED) power supply. The inductor heat-radiating type LED power supply mainly solves the problems that an existing inductor is large in calorific value and big in size, and the prior art is not reasonable in structure. The inductor heat-radiating type LED power supply comprises a circuit board, a power supply box body and a power supply box cover. The circuit board is fixedly arranged in the power supply box body and is fixedly arranged on the bottom board of the power supply box body. An inductor is arranged on the side wall of the power supply box body, and is electrically connected with the circuit board. The inductor is formed by winding fine wires with a diameter smaller than 0.01mm. The power supply box cover is U-shaped, and comprises a power supply box cover top cover and side covers symmetrically arranged on two sides of the top cover, a plurality of strip-shaped holes used for radiating heat are respectively formed in the top cover and the side covers, and inserting type groove holes used for leading out power lines are further formed in the side covers. The fine wires with the diameter smaller than 0.1mm are adopted, and effective area is increased, and the size of the inductor is reduced. The duty ratio of the power supply box cover is reasonable in design, and the inductor heat-radiating type LED power supply is high in strength, beneficial for being processed, and low in cost.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to a kind of inductance heat dissipation LED power supply.
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 supply lid structure setting of existing LED power supply is comparatively unreasonable, is unfavorable for heat radiation, also may cause foreign material to fall in power supply, thereby cause the generation of the problems such as power supply short circuit.
Summary of the invention
The invention provides a kind of inductance heat dissipation LED power supply, mainly solved existing inductance caloric value large, volume is large; The problem of prior art unreasonable structure.
Concrete technical solution of the present invention is as follows:
A kind of inductance heat dissipation LED power supply, comprise wiring board, power supply box body and power supply lid, above-mentioned wiring board is fixedly installed in the power supply box body, and 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 supply lid is U-shaped, comprises that the power pack caping covers and be symmetricly set in the limit lid at top cover two ends, and above-mentioned top cover and limit cover a plurality of bar holes that are useful on heat radiation all are set, and the limit covers the slotting formula slotted eye that also is provided with for extracting power supply cord; The width of above-mentioned bar hole is less than 3mm; The above-mentioned bar hole gross area with account for power pack caping capping long-pending more than 60%.
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, power supply lid dutycycle provided by the invention arranges rationally, and intensity is high, is beneficial to processing, and cost is low.
