Abstract
The utility model provides a power vacant-type LED (light-emitting diode) power supply, mainly aiming at solving the problems that the existing power pipe has poor heat radiating performance, and the pipe pin has great stress; and the existing power vacant-type LED power supply has poor heat radiating performance and cannot work in a high-temperature and high-humidity environment. The power vacant-type LED power supply comprises a circuit board, a power supply box body and a power supply box cover; the power supply box body comprises a power supply box body side wall and a power supply box body bottom plate; the circuit board is fixedly arranged on the power supply box body bottom plate; the power pipe is electrically connected with the circuit board and is fixedly arranged on the power supply box body side wall; a vacant unit is independently and vertically arranged on the circuit board and has the working temperature of minus 40 DEG C-100 DEG C. According to the utility model, the power pipe is adopted to be arranged on the power supply box body side wall, namely the problem of heat radiating is solved, and also the problem of pipe pin stress is solved; and the vacant unit can be replaced independently, and an air duct can be formed through the vertical arrangement, thereby being beneficial to air flow ventilation so as to take heat away, and further improving the heat radiating effect.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to the vacant type LED power supply of a kind of power.
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.
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.
Summary of the invention
The present invention provides a kind of power vacant type LED power supply, has solved mainly that existing power tube heat dispersion is poor, pin stress is big; The existing vacant type LED power supply heat sinking of power poor performance, the problem of working in the hot and humid environment again.
Concrete technical solution of the present invention is following:
The vacant 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, 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; 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 ℃.
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.
Description of drawings
Fig. 1 is the structural representation of the vacant 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.
