The utility model provides an integral distance type LED (Light-Emitting Diode) power source for heat radiation, which mainly solves the problems that the prior art has defects of poorer heat conduction property, poorer strength and unreasonable structure, and the conventional LED power source circuit board is unreasonable to arrange and inconvenient to mount and maintain. The distance type LED power source for the heat radiation provided by the utility model comprises a circuit board, a power source box body and a power source box cover; one side of a bottom board of the power source box body, which is far away from the circuit board, is entirely adhered to a part to be mounted; the bottom board of the power source box body and a side wall of the power source box body integrally form an insulating heat conduction box; the power source box cover is U-shaped; and a gap which is less than 5 mm is arranged between the circuit board and the bottom board of the power source box body. The power source cover body provided by the utility model is an integrated part and has uniform heat radiation and high strength. The power source box cover has the advantages of reasonable arrangement of duty ratio, high strength and low cost, and is good for machining. According to the LED power source provided by the utility model, the gap is arranged between the circuit board and the bottom board of the power source box body, can be used as an air duct so as to be good for forming an air flow, and enables the LED power source to be more conveniently mounted and maintained.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to a kind of one heat radiation spacing type LED power supply.
Background technology
The existing power supply box body is generally the split part, cause the intensity of power supply box body lower like this, and the each several part heat dispersion is inconsistent, is unfavorable for heat radiation; Simultaneously, does not generally handle existing power supply box body bottom, and it is not tight to cause power supply bottom and mounted piece to be fitted, and is unfavorable for the heat conduction.
The setting of existing power supply lid structure is comparatively unreasonable, is unfavorable for heat radiation, also possibly cause foreign material to fall in the power supply, thereby cause the generation of problems such as power supply short circuit.
In the existing LED power supply, generally be that wiring board is fitted on the power supply box plate, this mounting means at first is unfavorable for heat radiation, and secondly, also comparatively complicated when installing and fixing, unreasonable structure wastes time and energy.
Summary of the invention
The present invention provides a kind of one heat radiation spacing type LED power supply, and it is relatively poor mainly to have solved prior art heat-conductive characteristic and intensity; The prior art unreasonable structure; Existing LED power circuit plate is provided with unreasonable, the problem of installation and maintenance inconvenience.
Concrete technical solution of the present invention is following:
A kind of one heat radiation spacing type LED power supply; Comprise wiring board, power supply box body and power supply lid; Above-mentioned wiring board is fixedly set in the power supply box body; Above-mentioned power supply box body is " U " type or " L " type, comprises power pack body sidewall and power supply box plate, and wiring board is fixedly set on the power supply box plate; Above-mentioned power supply box plate away from circuit board one side be mounted the position and fit the insulating heat-conductive box that power supply box plate and power pack body sidewall are formed in one fully; Above-mentioned power supply lid is the U type, 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 and also is provided with the slotting formula slotted eye that is used 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%; Be provided with gap between above-mentioned wiring board and the power supply box plate less than 5mm; Be provided with at least three pad posts between above-mentioned wiring board and the power supply box plate, the length of pad post equates with the gap less than 5mm; Above-mentioned wiring board is fixedly set on the power supply box plate through screw, and screw passes the power supply box plate successively and is fixedly connected with wiring board with the pad post again, and the pad post is provided with and the suitable internal thread of screw external screw thread.
The invention has the advantages that:
1, power supply box body provided by the invention is an integral piece, and heat radiation is even, and intensity is high; Simultaneously, the box body back is handled, make its with mounted piece between contact closely, be beneficial to the heat conduction.
2, power supply lid dutycycle provided by the invention is provided with rationally, and intensity is high, is beneficial to processing, and cost is low.
3, in the LED power supply provided by the invention, be provided with the space between wiring board and the power supply box plate, the air channel at first can be regarded in this space, is beneficial to the formation air-flow, and secondly, installation and maintenance is comparatively convenient.
