Abstract
The utility model provides a spacing type LED power supply, and mainly solves the problems that the existing LED power circuit is unreasonable in arrangement and inconvenient to mount and maintain. The spacing type LED power supply includes a circuit board, a power supply box body and a power supply box cover, wherein the circuit board is fixedly arranged in the power supply box body, the power supply box body is U-shaped or L-shaped, at least three cushion pillars are arranged between the circuit board and a bottom plate of the power supply box body, and the length of each cushion pillar is smaller than 5mm and is equal to that of the interval. In the spacing type LED power supply provided by the utility model, the interval is reserved between the circuit board and the bottom plate of the power supply box body, can serve as an air channel to facilitate airflow generation firstly, and then is more convenient to mount and maintain.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to a kind of spacing type LED power supply.
Background technology
LED is because numerous advantages such as environmental protection, life-span length, photoelectric efficiency height; Use in every profession and trade in recent years and be able to fast development, the driving power of LED has become the focus of attention, in theory; The service life of LED is more than 100,000 hours; But in actual application,, LED is very easily damaged because the design of driving power and type of drive selection are improper.
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 spacing type LED power supply, mainly solved existing LED power circuit plate be provided with unreasonable, the problem of installation and maintenance inconvenience.
Concrete technical solution of the present invention is following:
A kind of 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, 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 set on the power supply box plate; 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 clearance height 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:
In the 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 spacing type LED power supply of the present invention.
Wherein: 5-power supply box body; 8-pad post.
