Abstract
The utility model provides a power tubes and vacant units integrated LED power supply, and mainly solves the problems that a conventional power tube is poor in heat dissipation and large in pin stress; a conventional power tubes and vacant units integrated LED power supply is poor in heat dissipation and can not work in high-temperature and high-humidity environments; and a conventional technology has poor heat conductivity and strength. The power tubes and vacant units integrated LED power supply comprises a circuit board, a power supply box body and a power supply box cover, wherein the power tubes are electrically connected with the circuit board and fixedly arranged on the side wall of the power supply box body; vacant units are independently and vertically arranged on the circuit board; and the side of the baseplate of the power supply box body, which is far away from the circuit board, is completely jointed with a mounted part. According to the utility model, as the power tubes are arranged on the side wall of the power supply box body, the problems of both poor heat dissipation and large pin stress are solved; as the vacant units are vertically mounted on the circuit board, heat dissipation is easy; and the power supply box body which is an integrated piece is uniform in heat dissipation and high in strength.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to the vacant one-piece type LED power supply of a kind of power.
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.
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.
Summary of the invention
The present invention provides a kind of power vacant one-piece type LED power supply, has solved mainly that existing power tube heat dispersion is poor, pin stress is big; The existing vacant one-piece type LED power supply heat sinking poor performance of power is worked in the hot and humid environment again; The problem that prior art heat-conductive characteristic and intensity are relatively poor.
Concrete technical solution of the present invention is following:
The vacant one-piece type LED power supply of a kind of power; 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; Be fixed with power tube on the above-mentioned power pack body sidewall, power tube is electrically connected with wiring board; Above-mentioned 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 ℃; Above-mentioned power supply box plate away from wiring 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.
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, 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.
Description of drawings
Fig. 1 is the structural representation of the vacant one-piece type LED power supply of power of the present invention.
Wherein: the 2-power tube; The vacant unit of 3-; 5-power supply box body.
The specific embodiment
The vacant one-piece type LED power supply of a kind of power; 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; Be fixed with power tube on the above-mentioned power pack body sidewall, power tube is electrically connected with wiring board; Above-mentioned 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 ℃; Above-mentioned power supply box plate away from wiring 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.
