Abstract
The utility model provides a power spacing type light emitting diode (LED) power supply and mainly solves the problems of low heat dissipation performance and big pin stress of the conventional power tube and unreasonable circuit board design and inconvenient assembling and maintenance of the conventional power spacing type LED power supply. The power spacing type LED power supply comprises a circuit board, a power supply box body and a power supply box cover, wherein the circuit board is fixed in the power supply box body; the circuit board is fixedly arranged on a bottom plate of the power supply box body; power tubes are fixed on the side wall of the power supply box body and are electrically connected with the circuit board; and a gap which is less than 5 mm is formed between the circuit board and the bottom plate of the power supply box body. According to the power spacing type LED power supply, the problems of heat dissipation and pin stress are solved by arranging the power tubes on the side wall of the power supply box body; and the gap which is formed between the circuit board and the bottom plate of the power supply box body can serve as an air channel for the convenience of forming an air flow and the assembling and maintenance of the power spacing type LED power supply.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to a kind of power spacing type LED power supply.
Background technology
The power tube of existing LED power supply generally is set directly on the wiring board, causes heat comparatively concentrated like this, 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 the stress of pin like this, and long-term the use is prone to cause potential safety hazard.
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 power spacing type LED power supply, has solved mainly that existing power tube heat dispersion is poor, pin stress is big; Existing power spacing type 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 power spacing type LED power supply; Comprise wiring board, power supply box body and power supply lid, said wiring board is fixedly set in the power supply box body, and said power supply box body is " U " type or " L " type; Comprise power pack body sidewall and power supply box plate, wiring board is fixedly set on the power supply box plate; Be fixed with power tube on the said power pack body sidewall, said power tube is electrically connected with wiring board; Be provided with gap between said wiring board and the power supply box plate less than 5mm.
Be provided with at least three pad posts between wiring board and the power supply box plate, the length of pad post equates with the gap less than 5mm.
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 pad post of power supply is 4, and each fills up post and is symmetrical set, and the distance between wiring board and the power supply box plate is 3mm, and the length of pad post is 3mm.
The invention has the advantages that:
1, 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 processed, and power tube is completely fixed and be fitted on the power pack body sidewall; Promptly solve heat dissipation problem, solved the stress problem of pin again.
2, in the power spacing type 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.
Description of drawings
Fig. 1 is the structural representation of power spacing type LED power supply of the present invention.
Wherein: the 2-power tube; 8-pad post; 5-power supply box body.
The specific embodiment
A kind of power spacing type LED power supply; Comprise wiring board, power supply box body and power supply lid, said wiring board is fixedly set in the power supply box body, and said power supply box body is " U " type or " L " type; Comprise power pack body sidewall and power supply box plate, wiring board is fixedly set on the power supply box plate; Be fixed with power tube on the said power pack body sidewall, said power tube is electrically connected with wiring board; Be provided with gap between said wiring board and the power supply box plate less than 5mm.
Be provided with at least three pad posts between wiring board and the power supply box plate, the length of pad post equates with the gap less than 5mm.
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 pad post of power supply is 4, and each fills up post and is symmetrical set, and the distance between wiring board and the power supply box plate is 3mm, and the length of pad post is 3mm.
