Abstract
The utility model provides a vacancy spaced light-emitting diode (LED) power source which mainly solves the problems that an existing vacancy spaced LED power source has a poor heat dissipation performance, can not work under high temperature and high moisture, has an unreasonably arranged circuit board and can not conveniently be installed or maintained. The vacancy spaced light-emitting diode (LED) power source comprises a circuit board, a power source box body and a power source box cover. A vacancy unit is separate and perpendicularly arranged on the circuit board. A gap less than 5mm is arranged between the circuit board and a base plate of the power source box body. At least three cushion posts are arranged between the circuit board and the base plate of the power source box body. The vacancy spaced light-emitting diode (LED) power source has the advantages that the vacancy unit is vertically installed on the circuit board to form an air channel and thereby the air flow can take away heat and the heat dissipation effect is further strengthened. The gap arranged between the circuit board and the base plate of the power source box can function as an air channel which is beneficial to forming an air flow. With the gap, the vacancy spaced light-emitting diode (LED) power source is convenient to install and maintain.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to a kind of vacant spacing type LED power supply.
Background technology
The vacant unit of existing LED power supply 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.
Existing LED power supply generally is that wiring board is fitted on the power supply box plate, and 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 vacant spacing type LED power supply, has mainly solved existing vacant spacing type LED power supply heat sinking poor performance, works in the hot and humid environment again; Existing vacant 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 vacant 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; Wiring board is provided with vacant unit, and 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 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.
2, in the vacant 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 the vacant spacing type of the present invention LED power supply.
Wherein: the vacant unit of 3-; 5-power supply box body; 8-pad post.
The specific embodiment
A kind of vacant 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; Wiring board is provided with vacant unit, and 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 this 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.
