Abstract
The invention provides a power non-occupation self-control type light-emitting diode (LED) power supply which mainly solves the problems that an existing power tube is poor in heat dissipation performance and large in base pin stress, an existing power non-occupation self-control type LED power supply is poor in heat dissipation performance and can not work in a hot and humid environment, and the power supply is prone to being damaged due to the fact that an adjustment of the power supply to be adapted to the environment can not be achieved in the prior art. The power non-occupation self-control type LED power supply comprises a circuit board, a power box body and a power box cover. A power tube is connected with the circuit board in an electrical mode, and the power tube is fixedly arranged on the side wall of the power box body. A non-occupation unit is independently and vertically arranged on the circuit board, and a control device is arranged on the circuit board. According to the power non-occupation self-control type LED power supply, the power tube is arranged on the side wall of the power box body, and not only is the heat dissipation problem solved, but also the stress problem of a base pin is solved. The installation mode that the non-occupation unit is vertically arranged on the circuit board is adopted, and thus heat dissipation is easy. The control device is additionally arranged. The power supply is prevented from being damaged, and the service life of the power supply is prolonged.
Description
Technical field
The present invention relates to the LED lighting field, especially relate to the vacant automatic control type LED of a kind of power power supply.
Background technology
The power tube of existing LED power supply generally is set directly on wiring board, causes like this heat comparatively concentrated, 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 like this stress of pin, and long-term use easily causes potential safety hazard.
The vacant unit of existing LED power supply is generally positioned on wiring board, and this set-up mode is unfavorable for heat radiation, is not suitable for the normal operation of hot and humid environment.
Existing LED power supply does not all arrange control device, causes like this power supply, can't in time cut off power supply, or reduce power when too high in excess Temperature or humidity, and power supply is damaged.
Summary of the invention
The invention provides the vacant automatic control type LED of a kind of power power supply, solved mainly that existing power tube heat dispersion is poor, pin stress is large; The existing vacant automatic control type LED of power power supply heat sinking poor performance is worked in hot and humid environment again; Prior art can't be done the adjustment that is adapted to environment to power work, causes the flimsy problem of power supply.
Concrete technical solution of the present invention is as follows:
The vacant automatic control type LED of a kind of power power supply, comprise wiring board, power supply box body and power supply lid, above-mentioned wiring board is fixedly installed in the power supply box body, 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 installed on the power supply box plate; Above-mentioned power tube is electrically connected to wiring board, and power tube is fixedly installed on the power pack body sidewall; Above-mentioned vacant unit independently is vertically installed on wiring board, and the operating temperature of vacant unit is-40 ℃～100 ℃; Be provided with on above-mentioned wiring board for when the power supply excess Temperature, or power supply ambient humidity of living in is used for when higher cutting off the electricity supply or reduces the control device of power, control device is electrically connected to wiring board.
Above-mentioned control device comprises temperature sensor and controller, and the said temperature sensor is fixedly installed on the power pack body sidewall, regulates the power output of power supply or closes after the temperature of controller reception temperature sensor or moisture signal.
Above-mentioned control device comprises temperature sensor and on-off controller, and the said temperature sensor is fixedly installed on the power pack body sidewall, and the measurement temperature of temperature sensor or humidity is during higher than the thresholding of on-off controller, the direct powered-down of on-off controller.
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 made, and power tube is completely fixed and be fitted on the power pack body sidewall, namely solve heat dissipation problem, solved again the stress problem of pin.
2, the present invention takes vacant unit setting mounting means is in the circuit board arranged easy heat radiation like this, can carry out independent replacing to vacant unit, is applicable to hot and humid environment, can at-40 ℃～100 ℃, work in 90% humidity environment; When in power supply, humidity was larger, 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, the present invention has set up control device in the vacant automatic control type LED of power power supply, and this control device is used for, reducing power or power supply being cut off when too high in excess Temperature or humidity, has avoided the damage of power supply, has extended the service life of power supply.
