Abstract

The utility model provides a power vacant spacing type LED (Light Emitting Diode) power supply. The power vacant spacing type LED power supply mainly solves the technical problems that the present power tube is poor in radiating property and big in pin stress, the present LED power supply is poor in radiating property and cannot work under a high-temperature high-humidity environment, and the present LED power supply circuit board is unreasonable in arrangement and inconvenient in mounting and repairing. The power vacant spacing type LED power supply comprises a circuit board, a power supply box and a power supply box cover, wherein a power tube is fixedly arranged on a side wall of the power supply box; a vacancy unit is independently and vertically arranged on the circuit board; a space less than 5mm is arranged between the circuit board and a base plate of the power supply box; and at least three cushion pillars are arranged between the circuit board and the base plate of the power supply box. The radiating problem and the stress problem of the pin are both solved by the power vacant spacing type LED power supply; the vacancy unit is vertically mounted on the circuit board, thereby being easy to radiate; and the space is arranged between the circuit board and the base plate of the power supply box, thereby being convenient in mounting and maintaining.

Description

The vacant spacing type of power LED power supply

Technical field

The present invention relates to the LED lighting field, especially relate to the vacant spacing type of a kind of power LED power supply.

Background technology

Existing power tube 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.

Existing vacant unit is generally positioned on the wiring board, and this set-up mode is unfavorable for heat radiation, is not suitable for the operate as normal of hot and humid environment.

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 the vacant spacing type of a kind of power LED power supply, has solved mainly that existing power tube heat dispersion is poor, pin stress is big; Existing LED power supply heat sinking poor performance is worked in the hot and humid environment again; 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:

The vacant spacing type of a kind of power 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 tube is electrically connected with wiring board, and power tube is fixedly set on the power pack body sidewall; Above-mentioned vacant unit independently is vertically installed on the wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃; 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 pad post of above-mentioned 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, the present invention takes mounting means is in the circuit board erect in vacant unit, is provided with like this to be prone to heat radiation, can carry out independent replacing to vacant unit, is applicable to hot and humid environment, can be at-40 ℃～100 ℃, and operate as normal in 90% humidity environment; When humidity in the power supply was big, dew can flow down along the wiring board of erectting; Simultaneously, erect setting and can form the air channel, be beneficial to airflow and take away heat, further improved radiating effect.

3, in the vacant spacing type of the power provided by the invention LED power supply, 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.
